Problems needing attention in hydropower transformation

Matters needing attention in waterway reconstruction?

1. Confirm all hydropower plans and construction personnel licenses, including drainage plans and water intake systems, and investigate the water supply system. In addition, pay attention to whether the personnel have Class A and Class B licenses. ?

2. Confirm all kinds of PVC pipes used to determine whether the pipes are used according to regulations. For example, PVC pipes have atmospheric pipes A, B and E, and cannot be mixed. ?

3. Pay attention to the construction method of metal pipe for hot water. There are two common combinations of metal pipe atmosphere for hot water, one is single tooth type and the other is pressure welding type. The single tooth type should be careful not to be too deep, the depth of tooth pattern should be controlled well, and the water stop should be wound reliably. When crimping, the crimping type shall not be over-pressured. If you press it too hard, it will sink in and cause water seepage.

4. Pay attention to the reliability of each joint. If there is a bent pipe, pay attention to the proper angle of the bent pipe to avoid warping, and avoid scalding when baking the PVC pipe.

5, the pipeline should be fixed to avoid excessive vibration in subsequent use.

6. Confirm the diameter and slope of the water pipe to be used. The slope of the drainage pipe depends on the pipe diameter. The smaller the pipe diameter, the greater the drainage slope. When erecting water pipes, it is necessary to confirm the appropriate pipe diameter and slope in advance. ?

Matters needing attention in circuit transformation?

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. Circuit design should also pay attention to its flexibility, and sometimes it cannot be too "comprehensive". Summarize a simple principle: consider connecting a patch panel in a place where electrical plugs are concentrated in the future, and the effect is often better than setting a wall-full socket;

2, the location of the socket is very important, often the socket is located directly behind the bedside table, resulting in the cabinet can not be against the wall. It is generally not wrong to make the socket as well as possible, but if the socket is left in an inappropriate position, it may conflict with the furniture placement or electrical installation in the later period. Students should remember; ?

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

4. Some kitchen sockets are convenient to switch, which avoids the inconvenience of unplugging the rice cooker frequently in the future.
