Precautions for hydropower installation Knowledge of hydropower installation

Pay great attention to the installation of water and electricity, because this is a hidden project. Once you don't pay attention to it, it will be very troublesome to change it after installation, so the precautions for water and electricity installation can not be ignored. So what are the precautions for hydropower installation? Come with us to get to know it!

Matters needing attention in hydropower installation

A, waterway installation matters needing attention

1. When designing waterways, we should first consider what water appliances are available, such as water heaters, washing machines, toilets, washbasins and kitchen sinks. Where to put it, how to install it, and whether hot water is needed.

2. In order to avoid repeated transformation of waterways, it is necessary to determine whether to use gas or electric water heater for bathing before design.

3. In addition, there are washbasins, mops, toilets and washing machines. The position of the reserved water outlet in the bathroom should be taken out one by one to facilitate water collection and floor washing in the future.

4. After determining the position of the washing machine, you can consider making the drainage pipe of the washing machine in the wall, which is more beautiful. 5. After waterway reconstruction, pressure test should be carried out.

6 All water pipe joints shall be firm and reliable with good sealing performance.

7. Check the drainage pipes in the kitchen and bathroom when closing the house to see if the water volume is normal. If the drainage is slow, the property should be dredged in time, and the drainage outlet should be protected during decoration to avoid cement falling into the drainage outlet during tile laying, resulting in blockage.

The most important thing is that the floor drain of the washing machine cannot be sealed by deep water. The disadvantages of deep-water sealed floor drain are slow launching, fast drainage speed and large quantity of washing machine. Can not meet the requirements of deep-water sealed floor drain, which will lead to water overflow.

Second, the circuit installation matters needing attention

1. When installing wires, all wires must pass through PVC pipes. The wire lines in the same pipe should be the same, and the wire size should be appropriate. The cross-sectional area of the pipeline should be less than 40% of the cross-sectional area of PVC pipe.

2. Where there is no internal corner on the ceiling and there is a wall with variable diameter, the wires should go through the wall.

3, wire bending should be less than 90 degrees, more than 90 degrees with pipe fittings. The strength of the wire must be threaded separately. Reasonable line layout

4. The position of the switch socket shall be 1200- 1300MM from the ground, and the socket shall be 300-450MM from the ground. The position must meet the requirements.

5. If the indoor area is more than 40 square meters, the air conditioning line shall be laid with 4 square millimeter BV copper core.

6, three-phase plug electrical appliances, to install reliable grounding wire.

Bian Xiao concluded: The above are the matters needing attention in water and electricity decoration and the knowledge of water and electricity installation. I hope it will help everyone.
