What's particular about hydropower installation design?

What's particular about hydropower installation design? First, the waterway part.

1, waterway design should first consider all water-related equipment, such as water heaters, water purifiers, kitchen treasures, water softeners, washing machines, toilets, washbasins, etc. Their locations, installation methods and whether hot water is needed;

2, want to use gas or electric water heaters in advance, to avoid temporary replacement of water heaters, resulting in repeated transformation of waterways;

3. In addition to the washbasin, mop pool, toilet, washing machine and other water outlets, it is best to take out another one to facilitate water collection and floor washing in the future;

4. After the location of the washing machine is determined, the drainage pipe of the washing machine can be considered in the wall, which is beautiful and convenient;

5. After channel reconstruction, there should be a suppression test. Under normal circumstances, the pressure of home improvement projects can reach 8.

6. It is best to have a property on-site suppression test, which can play a supervisory role; Because some decoration teams will cheat the owners in this link. The method is: when pressing, open the "return valve" of the pressing pump to form a loop. Although the pump seems to be working, the pressure in the pipeline is not great, especially for the electric pump, we should pay more attention to it.

7. Pay attention to check whether the drains in the kitchen and bathroom are unobstructed when closing the house. If the drainage is slow, the property should be dredged in time; Protect the drain when decorating, especially when laying kitchen and bathroom tiles, which is most likely to cause cement to fall into the drain and cause blockage;

8. After the kitchen and bathroom floor tiles are laid, check whether the floor drain is unobstructed (the drainage speed after removing the floor drain cover shall prevail, because most deep-water sealed floor drains have the problem of slow drainage);

9. If you want to close the redundant floor drain, you must block the gap between the drain pipe and the floor drain with glass glue or cement to prevent water from overflowing and returning to odor.

10, and another point is particularly important. It is best not to use deep-water sealed floor drain for washing machine floor drain, mainly because deep-water sealed floor drain has a common feature of slow launching, which is used for deep-water sealed floor drain in shower room and other places. Because the displacement is not large, the floor drain can basically meet the drainage demand; However, the drainage speed of washing machine is very fast, which can not reach the drainage speed of deep-water floor drain at all, which directly leads to water overflow;

1 1. In waterway reconstruction, four points should be paid attention to for the cold and hot water supply pipes reserved for installing electric water heaters and faucets in the future:

A, ensure the spacing of 15cm (at present, the spacing between hot and cold water of most electric water heaters and faucets is 15cm, and some are10cm);

B, hot and cold water nozzle height is consistent;

C, cold, hot water nozzle vertical wall, later build by laying bricks or stones wall also should pay attention to don't let bricklayer get crooked (not vertical, later installation will be very difficult);

D, cold, hot water nozzle should be two centimeters higher than the wall, in the wall brick, also should ask the bricklayer to ensure that the wall brick and water pipe nozzle in the same level. If the size is not suitable, install electric water heaters, faucets, etc. In the future, it may be necessary to purchase additional connectors, such as pipe clamps and internal wires, to complete the installation;

12, don't forget that the bathroom floor is waterproof, especially the slotted floor. If the shower area is not a closed shower room, the wall waterproof should be 180 cm high. Be sure to do a 24-hour closed water test before plastering cement, and bricklaying can only be done if there is no problem;

Second, the circuit part.

The design of 1. circuit must be determined after considering the possibility, feasibility and availability in detail. No one wants to pull wires everywhere on the walls and floors of their new home. At the same time, we should pay attention to its flexibility in circuit design. In the future, when the electrical plugs are concentrated, it is often better to connect a patch panel than to set up a full-wall socket.

2, the bedroom ceiling light can consider dual control (bedside and porch);

3. According to the needs of life, the ceiling lamp in the living room can be equipped with a separate control switch (in the porch hall, facing away from the master bedroom door);

4. When the circuit is reformed, the surrounding audio lines should be buried.

5, pay attention to the strong and weak wires can't be in the same pipe, there will be interference;

6. If the living room, kitchen and bathroom are tiled, some positions can be properly considered without slotting wiring;

7. The socket is generally 30CM from the ground and should not be less than 20CM. If the living room uses a low cabinet as a TV cabinet, it can be higher from the ground to avoid the TV cabinet blocking the socket and not leaning against the wall alone. Turnouts are generally off the ground130cm; The decoration designer of Wutang particularly emphasized that it is the most humanized arrangement to let the owner book the furniture first, and then configure the upper, lower, left and right positions of the socket according to the size and plane layout of the furniture.

8, exhaust fan switch, telephone socket should be installed near the bathroom, rather than into the bathroom door wall;

9. Yuba should be installed near the shower room or bathtub, not in the center of the bathroom; Balcony, corridor, cloakroom can consider reserving sockets;

1 1. For the space with mirrors and coat hooks, the lighting near the mirrors should be considered;

12. Telephone lines should be preset in the living room, master bedroom and bathroom according to personal living habits and convenience;

13, a pipe has at most three lines, and remember: before decoration, how to calculate 1 meter should be clear, and it should be calculated according to the pipe, not the line;

14, how to charge the cassette must be explained in advance.

15, the location of the socket is very important, often the socket is behind the bedside table, which leads to the cabinet not being against the wall.

16, some kitchen sockets are convenient to switch, so as to avoid the inconvenience of unplugging the rice cooker from time to time in the future.

17, there is no need to set too many sockets behind the TV. In the future, it is best to connect a patch panel on the side of the TV.

18, the electrical specification requires that PVC pipes must be used for buried pipelines, and panels must be left for testing where there are joints. In practice, for the sake of beauty, many workers choose to block the panel. Let's weigh the pros and cons.

19. It is necessary to increase the capacity of the circuit according to the usage of household appliances, especially if the instant water heater is used, 4 square millimeters of wire must be used.

20, should communicate with workers clear intention, design ideas. And draw the actual circuit transformation route on the wall;

Third, the waterway integration part

1, before the water circuit transformation, you should ask the hydropower transformation company to measure the meters of hydropower transformation according to the elastic line. You should follow them at the scene and see how the line goes when they measure, even if the actual cost exceeds in the future, so that you will have a good idea.

2, water circuit transformation should leave drawings, take photos, it is best to indicate the size, because the installation of bathroom pendants, water heaters, cabinets and so on. In the later stage, punching holes in the bathroom wall is the most involved, which is easy to damage the water circuit pipeline if it is not handled properly.

3. The water circuit renovation is divided into two prices: no slotting and slotting. Some decoration teams subdivide the slotting price into two prices: "non-bearing wall slotting and bearing wall slotting";

4. Hydropower transformation is the biggest concealed project, and it is also the most expensive one among the additional projects. It can't be as much as the workers say, it depends on whether they take the pipe in the conventional way. For example, the deviation of going through the wall will make you walk around the wall. Originally, two pipes with one groove were forced into double grooves;

5. When decorating, you must order the following household appliances: water heater, range hood, gas stove, cabinet treasure, water softener and water purifier. These household appliances are directly related to waterway reconstruction and cabinet design, and their location design is particularly important. Students should know well before hydropower transformation. As for household appliances such as refrigerators, washing machines and microwave ovens, there is no need to buy them in a hurry. Just reserve the location of the socket.

Fourth, the wire construction

1, electrical wires are laid in flame-retardant concealed pipes, and there should be no knots and kinks in the pipes.

2. "The live wire enters the switch, and the neutral wire enters the lamp holder", and the wiring of the socket shall comply with the provisions of "grounding on the left zero and right fire".

3, air conditioning and high-power electrical appliances should be set separately (flame retardant tube processing).

4, the power cord, TV line, telephone line shall not be installed in the same pipe.

5, switch, socket installation is firm, the position is correct, the cover plate is correct, close to the wall, seamless around.

6, the power cord will affect the clarity of the telephone and TV, so the telephone line and TV line should be separated from the power cord.

7. The socket shall be no less than 200mm from the ground ... There shall be wire allowance in the box, and the length shall be 150mm. When wiring, the phase line enters the switch, and the zero line directly enters the lamp holder. Don't connect the phase line of screw cap to the shell. The lighting height from the ground should be 1.3mm, and the switch should not be installed behind the door.

8. The connection method is: If the socket is on the upper part of the wall, slot the wall vertically upwards, and install decorative corner lines on the top of the wall; If it is in the lower part of the wall, slot vertically downward to the bottom of the skirting board. The depth of the groove is about15 mm. Put the wire and conductor into the protective sleeve, lie in the groove on the wall, smooth it with cement mortar and fix it in the wall. If the original socket is retained, it should be reinstalled in the original location; If it is not retained, it should be filled with bricks and leveled with cement mortar. When installing the skirting board, the wires along the ground are located inside the bottom of the skirting board. When installing the decorative wire, the wires along the top corner are hidden in the decorative corner line.

9. PVC pipes are required for laying electrical lines and concealed pipes, and PVC trunking must be used for laying open wires. Avoid wall cracks caused by gouging during construction and damage to wall structure. When laying, it should be changed according to the number of wires in the pipe. There should be no more than four wires in the same tube. It is forbidden for wires to occupy all the space in the pipe. Air conditioning, lighting and sockets should be controlled by branches, generally at least four ways. Lighting all the way, air conditioning all the way, three or four sockets. The advantage of this is that once a line has a short circuit or other problems, the power outage range is small and will not affect the normal work of other lines. The distance between the power cord and the telephone line and TV line should be more than 50 cm, and the pipeline should be fixed with the structure. Junction boxes shall be installed at all switches, sockets and lights.

10, the grounding protection should be *, and the insulation resistance between wires and wires to ground should be greater than 0.5MΩ.

1 1. When laying wires through pipes, there shall be no joints or kinks in the pipes.

12. Fix the wire sleeve with wire clamp or inner wedge with iron wire.

13, the power cord head in the ceiling is protected by hose.

14, two-color line separation. Facing the power socket, the left hole is connected to the zero line and the right hole is connected to the phase line; For sockets with grounding holes, the grounding holes should be directly connected to them.

15. In the past, insulating tape, waterproof tape and capping were mostly used in the market. According to the person in charge of Wutang Decoration Engineering Department, Wutang Decoration took the lead in using the wire connector-German WAGO connector, which is safer and more convenient, achieving a high improvement from vision to quality, and truly embodying the safety of concealed works.

Verb (abbreviation of verb) pipeline installation

1, reasonable pipeline layout, firm laying, horizontal and vertical, smooth installation of switches and valves, flexible and convenient use.

2. The water supply pipeline and accessories are closely connected, and there is no leakage in the water pressure test. The water outlet is unobstructed and the water meter runs normally.

3, drainage pipes should be smooth, no blockage, no leakage, the bottom of the bathtub should be higher than the drainage bend, floor drain grate should be slightly lower than the ground.

4. It is best not to use deep water seal for the floor drain of washing machine, because the water flow is too slow to meet the needs of washing machine.

5, water reform project should pay attention to the direction of the pipeline. The load-bearing wall in the house is not allowed to be slotted, and the surface of the wall with insulation layer is easy to crack after being slotted.

6. Except the water outlet of washbasin, toilet, washing machine, etc. It's best to pick them up one by one. It's convenient to mop the floor after picking up the water.

7. Cement is not allowed to install toilets and wash basins.

8. The spacing between water pipes and electrical conduits should be at least150-200mm.

What is the focus of aviation battery design? Aircraft battery plate is thin, the electrolyte density is high, the internal resistance is low, the utilization coefficient of active substances is high, the starting efficiency is good, and it has the advantages of portability compared with weight and volume. The disadvantage is short service life, which is usually only 1/5 to110 of ordinary batteries. Aircraft batteries are equipped with heating or heat preservation devices to ensure normal operation in low temperature environment. Nickel-cadmium battery has been used in aerospace for a long time because of its long life. SAFT is a large battery supplier in the aviation industry, providing high-tech batteries for many civil and military aircraft. It recently signed a contract with Korea Aviation Industry Corporation to provide maintenance-free nickel-based batteries for its two military models.

What should be paid attention to in the geomantic design of Yangzhai? The geomantic omen of Yangzhai lies in whether it is auspicious to sit in the right direction, whether it is auspicious to stand in the right direction, and whether it is fierce to be angry. Therefore, there is a cloud in ancient books: the disaster of the early stars and the stars. The sitting direction in the geomantic omen of Yangzhai is not the door of the suite, but the entrance of the building.

To judge whether a building should be shipped or not, we should use the mysterious space method of three yuan and nine planets to calculate. There are two ways:

Collect mountains and water (the theory of zero gods and right gods), such as the Seventh National Games (1984- 2003), where the zero gods are east and the right gods are west. Therefore, there is water (or road) in the east, which is a financial house, and water in the west is a financial house.

Looking at the mountains and hometown (flying stars in the sky). For example, the seventh building, Yunwangshan Wangxiang, is an east-facing building.

Gate. The gate is very important in the geomantic omen of Yangzhai. In this paper, "door", "main" and "stove" are called three essentials. The door is the road. There is a cloud in "Eight Houses Mirror": "There is a gate at the head of Yang House, and the door is the air outlet, which is so prosperous and bad." There is another cloud: "The house takes the door as good or bad, and the road helps, and the door is divided into noble and low."

Gate selection method is as follows:

1, door match: Gua is a personal divination, which is often called Dong Si Ming and Xi Si Ming. According to this method, the door should cooperate with divination, and open the door on the angry side and all the year round to collect the prosperous gas.

2. Star-to-door: This method is calculated by Kong Xuan's geomantic method. In other words, the stars can turn mountains into evil spirits, and Ding and Cai Xingwang will be guaranteed. Fuxing (Shui) went to the door to see Master Zhenshui make a fortune, and Ding Xing went to the mountain to see Master Zhenshan Wang Ding.

3, zero righteousness: this is also a metaphysical feng shui method. No matter whether the gate is facing the water or the road, zero divination gas can be collected, and Zhenshan can collect correct divination gas on the spot.

What should be paid attention to in cabinet lighting design? The kitchen lighting system should be consistent. When the light is dark or blind, it can be aligned, and people will try to be comfortable and comfortable.

The heating of light should be consistent with the air in the room, and at most close to the opposite area and room temperature.

Third, don't put a single light source in the kitchen. For better kitchen lighting, it should be placed in a kitchen with stray light and light source.

Four lights can be placed in the top cabinet on the bottom floor to increase the shadow of the task time.

Five places are also important. Incandescent lamps or fluorescent lamps with vertical lines should be placed in FR. Left and right, the light from the circular lampshade will be reflected to the console at that time, and then centripetal in the kitchen. It can also be placed in a cupboard, which is superior to indirect lighting, such as a small lamp, which is not only unappreciable, but also shriveled when placed at hand.

Even if the kitchen is completely high and there is no news, the obvious or semi-obvious pendant that can be placed on the ceiling is L, which can not only be a good lighting pendant, but also a good decoration.

What is particular about the design of duplex stairs? To select materials, the solid wood should be painted. The paint brush I bought at 1 is on the steps, and I haven't dropped it yet. Very durable and lasting.

What is particular about the design of shower room? Reasonable stress structure design and smooth and bright lines are "innate" factors, while surface quality, assembly accuracy and movement efficiency of moving parts reflect the "acquired" quality of products.

If consumers decide to buy imported products, they should see clearly the origin and quality, so as to avoid spending more money but not achieving the desired results. Therefore, before buying a brand, we should have a comprehensive understanding of the enterprise and choose products with quality assurance.

1. Vertical corner shower room: square, arc and diamond in appearance, sliding door, folding door and hinge door in structure, with corner entrance or single entrance. The biggest feature of corner entry is that it can make better use of the limited bathroom area and expand the utilization rate. Common square diagonal shower rooms and arc shower rooms make better use of the limited bathroom area and expand the utilization rate.

2. I-shaped shower curtain: When some rooms are narrow in width or have a bathtub, but the householder chooses a shower curtain instead of using the bathtub, I use an I-shaped shower curtain.

3. Bath screen on the bathtub: Many families have installed bathtubs, but they often use showers. In order to take care of both, they can also make a shower screen on the bathtub. It is common to shorten the bathtub into a straight line or fold it completely, but the cost is high and uneconomical. "

What should be paid attention to in the design of lightning rod? The charge carried by an object tends to gather in the sharpest part of the object. People usually design the top of lightning rod very sharp. However, American scientist Moore and others found that although the sharp lightning rod produces a strong electric field, the electric field will soon weaken when it is far away, and the effect is not very satisfactory. If the top of the lightning rod is designed to be spherical, although the electric field nearby is not too strong, the influence range is larger.
