Many friends don't pay much attention to the renovation of water and electricity during the renovation process. This is a big mistake. If the hydropower project is not handled well, there are many safety hazards for our future life. Therefore, Xiaobian today brings you 20 experienced electrician's tears to summarize the hydropower acceptance techniques, so that we have a safe living environment. What are the precautions for water and electricity acceptance? 1. The hydropower transformation process should determine the fixed-point positioning, determine the location where construction is required, and mark the cassettes of each point with the eye-catching signs in combination with the design drawings to determine the position of the cassette. (In general, the height of the cassette needs to be the same as the position of the socket, sometimes encountering multiple cassettes together. At this time, it should be noted that the distance between the cassettes needs to be kept at least 10 mm and the position of the nozzle is determined. Mark out) 2. Slotting is the wire trough and water pipe trough that need to be wired. It should be noted that the width of the trough and the trough can be determined according to the materials to be used. (The principle to follow when slotting is: 1 the principle of the shortest line; 2 can not destroy the principle of the original strong electricity; 3 can not destroy the principle of waterproofing. It should be noted that the horizontal and vertical, uniform size, the depth and width of the groove At least 4 mm wider than the material used) 3, the kitchen is equipped with small lights. Generally, the home kitchen is only equipped with a ceiling lamp. But Xiao Bian here suggests that it is best to install a light on the gas stove and sink. Range hoods and gas stoves are usually on the same side. Some range hoods are equipped with spotlights, but some are not. When this happens, it is best to consider installing one above. 4. Leave a few wires in the bathroom. If some of the home bathrooms are heating and want to do air conditioning, it is necessary to leave 5 to 6 2.5 square wires more than the light. 5. Plan the room water potential according to the furniture. The placement of the furniture affects the location of the water and electricity in the room, as well as the number of switches, outlets, reserved cables and TV line interfaces. 6. The places to pay attention to when wiring and piping are: to ensure the smoothness of the line and pipeline, to use the elbow as little as possible, and to test after wiring; for example, when laying the cable and telephone line, you must test it. If it is not found to be unobstructed during wiring, then it will have to be re-applied after the demolition, which will cause unnecessary losses. By the same token, the water pipes should be checked for smoothness when wiring. 7. After the completion of the hydropower wiring, it must be tested for pressure. If the problem is found, it can be repaired in time. If the problem is found after other projects are completed, it is very troublesome to repair it again. 8. The whole house switch is in the same horizontal position. It is best to have the house in the same horizontal position, or the same level and the same level. Except for special sockets, such as refrigerators and air conditioners. The color of the phase and neutral lines in the circuit transformation should be the same for each room. It is best to indicate the color of the fire, neutral and control lines in the decoration contract. The yellow-green color is generally a protection line. 9. After the wiring of the line is completed, it is necessary to seal the slot. The main purpose is to fix the cassette and the tube. The requirements for the fixing of the cassette should be the same as the wall surface, and should be on the same horizontal line; the tube should be fixed once every one meter. 10, generally speaking, the family bathroom and the kitchen are a shared water heater, so you must first think about the installation position of the water heater when installing. The position of the electric water heater is generally fixed on the load-bearing wall; if the situation is special, it is not fixed on the load-bearing wall. To fix the bracket, also ensure that the top layer has enough position to make the bracket. Bathroom waterway installation. When installing the bathroom waterway, pay attention to the installation position of the washbasin, toilet, bathtub and washing machine. If you need hot water pipe, you must think ahead. The draining of the floor drain must be done well. If there is no water, the water will return. How to carry out hydropower acceptance? 1. Hydropower acceptance steps and tools Acceptance site: the owner of the construction supervision must be present At the time of acceptance, it is not only the construction party or the supervisor is present. The construction party, the owner and the supervisor must be present at the same time to check and accept the water and electricity of the home. After the acceptance is passed, the owner can sign the next step. Acceptance tools: size tools are indispensable Acceptance tools are generally prepared by the supervisor or the construction party. The tools include pressure test pump, flow wrench, raw material belt, plug, jack, pressure gauge, water tank, connecting hose, ammeter, etc. The owner can bring their own tape measure and small notebook. , small flashlights, etc., convenient to record and record various data in the field. Acceptance process: acceptance step by step In addition to the water and circuit acceptance, the acceptance can be divided into material acceptance, wiring inspection, pressure test and other project acceptance. Let's take a look at how the acceptance is done step by step. Material acceptance includes pipeline inspection of waterways and circuits, whether materials and lists belong to the same brand and model; whether the pipelines are damaged or not; The wiring inspection must see whether the wiring of the clean water circuit conforms to the specifications, including the distance, position, direction of the water pipe, and the distribution of the wires. Pressure and power test, pressure test must be carried out for waterway inspection, and circuit check should use current meter to test whether there is any problem in each channel. Finally, inspections of other details, such as drainage pipe conditions, drainage slope, wire box position, etc. 2, hydropower material inspection must be meticulous The first step in the acceptance of hydropower is to check the quality of the materials of the wires and pipes, and secondly to see the length of use, so that it can be settled in the future. Water pipe inspection: brand quality should be seen clearly First check if the brand of the water pipe is consistent with the list of decoration materials. At the construction site interviewed by Xiaobian, all the water pipes and tubes used Liansu PPR pipes. Hot and cold water pipes must have clear instructions, and hot and cold water pipes cannot be used as hot water pipes. Check the water pipe for scratches and hoses. These problems have a very important impact on the use of water pipes in the future. If problems are found, the construction party must immediately replace the pipes. Wire and Pipe Inspection: Material usage must be recorded Wire materials should see if the brand of the wire is consistent with the list. In this case, the paved wires are uniformly used with Qingfeng brand wires. Secondly, the wire tube that wraps the wire uses a plastic PVC pipe. Wire inspection needs to be clear. The wires used are reasonable. The wires of the neutral line, phase line (fire line) and ground wire must be different. They should not be mixed. Generally, the neutral line is blue, the phase line is red, and the ground line is It is a yellow-green thin line. To measure the total amount of line pipe, the owner can use the tape measure that comes with it to measure the total length of the pipeline to be laid with the constructor and make detailed records for later settlement of the renovation payment. 3. Hydropower pipeline layout check The layout of the pipeline is a question from the university. When conducting hydropower acceptance, it is necessary to see the following points to ensure the safety of household water use in the future. Water pipe wiring: horizontal and vertical distance requirements The wiring of the water pipe first requires "horizontal and vertical", and the direction of the pipe should be reasonable. Generally, the water pipes on the left and right and the up and down are balanced with the edge of the wall, and the water pipes are at an angle of 90 degrees. The distance between the hot and cold water pipes is generally about 10-15cm, and is laid according to the specifications of “left hot right cold, hot upper and coldâ€. The elbows of the hot and cold water pipes must be in the same plane, above the drain. The distance between the water pipe and the power supply and the gas pipe is exquisite, and the distance between the various pipes must be greater than or equal to 50 mm. Wire wiring: the distribution of strong and weak wires is clear The wire should be a live wire. When inspecting, the exposed wire can be pulled back and forth and should be able to move flexibly. There should be no joints and kinks in the wire tube, and the wire should remain arc-shaped at the bend. A certain distance must be maintained between weak current and strong power to avoid interference during use. All wire connectors should have a 15cm margin for future installation of the wire box panel. 4, water pressure test and circuit test The key step in hydropower acceptance is to suppress the test water and the use of the test circuit. These two steps are the key to checking the quality of the construction. Suppress the test water: the weight of time must know At the beginning of the waterway acceptance, the upper water pipe needs to be completely closed, and the pressure test is carried out. The pressure of the pressure is generally 0.6 MPa and closed for 24 hours. Check the pipeline for leaks. The owner can bring his own newspaper and lay it at the water pipe joint. After a period of time, observe whether the newspaper has water traces caused by leakage. After the water pipe passes through the water, check whether the water pipe is shaking or dripping. If the water pipe is shaken and loose, the construction party must be required to replace the water pipe. Circuit test: check the power usage Circuit test First check whether the wiring of the electric box is reasonable. The main switch of the household circuit is clearly classified. It is forbidden to use the same leakage switch for the whole house line. Also check if the leakage switch is flexible. Connect the loops in the home, check the currents of each loop with an ammeter or an ohmmeter, and the current indicates normal use. It is also possible to determine the use condition by checking the resistance value of the circuit. Generally, the insulation resistance value of each circuit is not less than 0.5 megohms. The above is some related information about the hydropower acceptance introduced by Xiaobian. We must not underestimate these processes and precautions. The concealed project of hydropower acceptance has a great impact on our home life. I hope that Xiaobian’s summary These can bring you help.

The most complete hydropower acceptance technique in history, 20 experienced old electricians summed up their tears.
Hydropower project is a concealed project, which is invisible in our daily life, but if we ignore it, it will bring us a lot of trouble after check-in. It will be complicated to remediate again, so we are inspecting and accepting the decoration. The problem of hydropower engineering should be handled well.
