Hydropower installation is a key hidden issue for home improvement, and it is also a concern for most owners. Hydropower is the soul and design center of the whole family. The quality of the installation of hydropower processes also affects the quality of life in the future. The following Xiao Bian tells everyone the knowledge of hydropower installation and water and electricity acceptance. Hydropower engineering installation knowledge 1. Slotting of pipelines: Construction method, first playing the line, and then grooving. Slotting of pipelines must be parallel lines and vertical lines according to requirements (better if there is a comparison of construction plans for hydropower projects). Pipes that are to be routed in parallel must be controlled at a height of 60-90 centimeters (counting from the ground). Pipes with faucets must be vertical. Depth control is 4 cm. After the slot is opened, the person in charge of the construction shall remember the size and position of the slotted pipeline. It is convenient to know the position of the pipe when installing the sanitaryware. 2, water pipeline installation: material requirements, PPR pipe, aluminum plastic pipe. Most users bought plastic tubes three years ago, and more users use PPR tubes in the past two years. The pipeline is divided into cold water pipes and hot water pipes. Hidden pipes eliminate the use of galvanized iron pipes. First of all, through the construction plan construction personnel and the owner to discuss the location and use of water functions. Arrange the water master to drain and install all taps and water positions. If there is a construction drawing, it can be arranged according to the construction drawing. If the waterway function of the construction drawing is not in place for a long time, communicate with the owner to increase the waterway use function. 3. Water pipeline inspection: Water pipeline inspection is very important, which is related to the future water safety hidden troubles. We usually use pressure testing to do pipeline inspections. Pressure test is one of the ways to check leaks in pipelines. First, all the inner wires are staked to death with a gambling head. Use a pressure gauge to suppress (12 pressures for home decoration) test water. Check all pipe fittings after pressure. The second method is to open the floodgates for two days and two nights, and check all joints on the third day. I generally take the former method. 4. Secondary waterproofing: After the water pipeline is installed, all the trunks in the bathroom shall be sealed with cement sand. After the trunking and the ground are dry, clean the floor and the wall again. The water on the wall surface can be used for waterproofing. It is best to make the wall waterproof one meter high. If there is a furniture wall on the back of the kitchen wall, it must be full of walls. Plays a damp-proof role for furniture. If the ground must be filled with slag, it must be filled with water after filling. Fill the slag more than 10 cm with cement sand dry mix slag. Do the secondary waterproof floor and the wall together. (There must be a friend here to ask me, when the ground comes into play, it has been waterproof once, why do it now?). The ground surface has been damaged when the water is used in construction of water and electricity, so it must be done together with the wall. The first time to enter the venue to do waterproofing is to be able to determine that the ground will not leak. After the pipeline is installed, the wall and floor will be re-doed once again to make the floor and wall more effective in waterproof protection. 5. Slotting of electric wire lines: After the construction person in charge consults with the landlord to discuss the functions and requirements of electric power, he shall make a connection with the master electrician and make the parallel and vertical line slots. Place the switch socket box. The socket type is slotted 40 cm from the ground, the hanging air conditioning socket is slotted 2.2 meters from the ground, and the switch is slotted from the ground 1.2-1.4 meters. The bottom of the switch socket is installed and the horizontal line is to be slotted. The kitchen and bathroom rooms must be slotted according to the designed function. 6, wire circuit wiring: timber requirements, 2.5-6 square meters above the copper wire, 16mm above the line tube. Wiring requirements: Most electrician masters did not consider the separation of strong and weak currents, switches, air conditioning sockets, and electrical outlets in the circuit wiring. So slotting also saves a lot of processes. The requirements for strong and weak power cables are 30 cm apart at the bottom of the limit, and the air-conditioning sockets are dedicated to groups of wires of more than 6 square meters, electrical sockets are dedicated to 4 square meters, and switches are grouped with more than 2.5 square meters. The air conditioning line group is more than 2 meters away from the ground. The ground wire of the electric wire group, the switch and the top line of the wall of the lamp line group. The bottom of the switch socket must be installed horizontally and vertically so that the rear panel installation will be evener. Hydropower acceptance skills Although during the mid-acceptance of the renovation project, the hydropower has been pressured and closed, the circuit installation has also been carried out for concealed project acceptance, and the water circuit project has been provided with basic quality assurance. However, the hydropower project also involves the installation of hydropower installation design, electrical fittings, lamps, electrical products, etc. Therefore, the hydropower project after renovation is still one of the focuses of project acceptance. Installation and acceptance of hydropower is mainly to check whether the pipeline is firm, you can open the tap to check the patency of the outlet pipe, and then check the position of the joints and elbows to see if there are drops of water or leakage, use a paper towel to wipe the joints, elbow to see if there is Water leakage phenomenon. In addition, it is also necessary to check whether there is a phenomenon of "flooding" and "backslope" in the room with floor drain. You can turn on the faucet or shower, and after a certain period of time, see whether the flowing water on the ground is smooth and there is no phenomenon of local accumulation of water. In addition to this, it is also necessary to check whether the floor drain, the toilet and the wash basin are clean. Water pipe acceptance: The galvanized pipe has not less than 8 teeth on the hinge, and the raw material is wrapped around more than 6 turns and tightened. No rotten teeth are allowed. Plastic pipe or aluminum plastic pipe Note that the installation of special tools, in strict accordance with the provisions of the operation, the final pressure test (pressure test is greater than 24 hours) These are the information provided by Xiao Bian on hydropower installation knowledge and hydropower installation and acceptance techniques provided by everyone today. We hope to help everyone.

Circuit installation acceptance is mainly through lighting test, switch control to check the lighting, power is normal, the owner can also use electrician professional test pencil to test each socket to see if it is power, and then all the switches are open to check if there is a problem .
