As we all know, hydropower installation is a very important part of home improvement. It is directly related to the hidden dangers of family safety. Therefore, it is necessary to make a detailed understanding of the basic knowledge of hydropower installation before doing hydropower installation. This is also for family members. Another kind of protection. Here we introduce: the size of the home water installation and water and electricity acceptance techniques.
Hydropower installation design common size:
In the hydropower installation design process, hydropower is installed in different places, and the required dimensions are also stressful:
1. Basin: 50 cm Shower: 120 cm Toilet: 20 cm Wash basin: 40 cm Mop pool: 75 cm Washing machine: 120 cm Electric water heater: 170 cm Gas water heater: 130 cm Bathtub: 35 cm Mixing valve between hot and cold water : 15cm.
2, kitchen equipment commonly used size: kitchen cabinet operating table height is 810-850mm; front and rear depth 500mm-600mm operating table to the end of the cabinet, the high size is about 550mm, too high is too low is not good; hanging cabinet shower outlet 1100mm.
3. Satellite TV sets the south-facing windows of the living room. The south-western direction is the direct broadcast of live Chinese (entertainment, national language) in Taiwan, and the southeast is CNN, BBC, HBO, and other full English programs. Place specific locations based on personal preferences.
4. The socket position is relatively consistent with the original socket position, generally 300-350mm.
5, dual control switch from the ground 850mm.
6, wall-mounted TV power supply to 1100-1300mm height in the 700 or so, too high to place items more laborious, thickness 300-350mm, range hood height above the stove is a standard height, in case of special circumstances, can be Properly change the distance from the bottom of the machine to 750mm.
Hydropower acceptance skills:
The first step: hydropower acceptance steps and tools
Acceptance tools generally have supervision or construction parties to prepare, tools include pressure test pumps, flow wrenches, raw tape, plugs, jacks, pressure gauges, water tanks, connecting hoses, ammeters, etc., owners can bring their own tape measure, small notebook , small Flashlights, etc., to facilitate the measurement and recording of various data in the field. Material acceptance includes pipeline inspections of waterways and circuits, whether the materials and checklists belong to the same brand and model, whether the conduits are damaged or not, and the length of use. The wiring inspection shall be based on whether the wiring of the clean water circuit complies with the specifications, including the distance, position, and direction of the water pipes, and the distribution of the wires. Pressure and electrical tests are required. Pressure test must be performed on the waterway inspection, and the circuit inspection needs to use an ammeter to test whether there are any problems in each channel. Finally, the inspection of other details, such as the condition of the drainage pipe, the drainage gradient, the position of the wire box, etc.
The second step: the hydropower material inspection must be detailed
The first step in hydropower acceptance is to inspect the material quality of wires and pipes, and secondly to look at the length of use for future settlement. First check whether the brand of the plumbing is the same as the list of decoration materials. For the site interviewed by Xiaobian, all plumbing pipes use Lianpian PPR pipe. Hot and cold water pipes must have clear instructions. Cold and hot water pipes cannot be used as hot water pipes. The wire material must see if the brand of the wire is consistent with the list. In this case, the paved wires used Qingfeng brand wires. Second, the hoses used to wrap the wires are connected to PVC pipes.
The third step: check the layout of the hydropower pipe
The layout of the pipeline is a question from the university. When it comes to hydropower acceptance, it is necessary to see the following points to ensure the safety of water for household use in the future. The wiring of the water pipes firstly requires “horizontal and verticalâ€, and the direction of the pipe should be reasonable. Generally, the left and right pipes and the upper and lower pipes are balanced with an angle of 90 degrees between the pipes. The wire should be a live wire. When checking, the exposed wire can be pulled back and forth. It should be able to twitch flexibly. There must be no joints or kinks in the wire line tube, and the wire should remain arcuate at the bend.
Step 4: Water pressure test and circuit test
The key steps for acceptance of hydropower are to suppress the test water and test circuit usage. These two steps are the key to checking the construction quality. When the acceptance of the waterway starts, the upper water pipe needs to be fully closed and a pressure test should be conducted. The pressure to be suppressed is generally 0.6 MPa and is closed for 24 hours. Check whether there is any leakage in the pipeline. The owner can prepare a newspaper and lay it at the joint of the water pipe. After a period of time, observe whether the newspaper has water traces caused by leakage. The circuit test first checks whether the wiring of the electrical box is reasonable, whether the main switch of the home circuit is classified clearly, and avoid using the same leakage switch in the whole house line. Also check that the leakage switch is flexible.
Editor's summary: Home installation dimensions and hydropower acceptance techniques are introduced here. Hope to help you. For more information, please follow this website.
