Hydropower general process:
Circuit: Bomb - Slot - Wire Pipe - Wiring - Fix
Waterway: Bomb - Slot - Pipe - Seal Outlet - Pressure
Stretching line: After the electrician has determined the position of the switch, socket, water pipe and wire tube according to our requirements, draw lines manually on the wall. The length of the line shall be no more than 20cm (as far as possible). , take the shortest route, this process requires higher professional knowledge of the workers, this step is the basis for the entire hydropower reform, but also can directly measure the actual number of projects.
Slotting: Use a cutting machine and a hammer to open the slot. This process requires the workers to be skilled in the use of cutting machines in order to cut them strictly in accordance with the line, but also to be careful not to damage other walls.
Pipe: According to the slotted pipe, the same slot is not allowed to double pipe, single pipe does not have many lines, strength and weakness are separated.
Wiring: After laying the wall pipe, all connections are required to be connected. Use insulating tape and do not leak the copper core.
Fixation: Before fixing the pipes in all the wall tanks, circuit modification plans should be issued. The top surface pipes must use elevators to fix the pipes.
General owners should have a simple standard for acceptance of hydropower:
1. Whether electrical products are qualified products that meet relevant standards.
2, the use of fire-retardant dark pipe laying, the conductor should not have knots and kinks in the pipe, so as not to cause the line can not be changed 2 times.
3. It is forbidden to directly bury the wires in the plaster layer.
4, "Fire line into the switch, the zero line into the lamp", socket wiring should meet the "left zero right fire ground on the" provisions.
5, air conditioning and high-power electrical appliances should be set up alone, the line should use 4 square millimeters line.
6, power lines, television lines, telephone lines must not be installed in the same pipeline.
7. The switches and sockets are firmly installed and the position is correct. The cover plate is upright, close to the wall, and there is no gap around. After the installation of electrical engineering, electrical power should be provided, lighting test light, switch control and so on. After the completion of the project, the customer shall be provided with wiring drawings showing the wire specifications and directions.
8. The elbow should not be bent at the turning point of the electric pipe. It must be inserted into the pipe by a spring. The number of elbows under normal conditions should not exceed 3.
9, the color of the wire should also be implemented in accordance with the specification. Should be: red, blue, two-color line, white.
Electrician series of common problems:
1, excessive line joints and improper handling of joints are prominent reasons. Some lines are too long and some joints will be produced when the electrician operates. However, due to the limitation of technical level or lack of sense of responsibility of some electrician masters, it is not easy to wire, insulate and moisture-proof the connectors, and disconnection and short circuit will occur. Prevention Tips: Route to minimize connectors. If wiring is necessary, the distribution line must be well-connected, insulated, and moisture-proof. If conditions permit (under the appropriate engineering quotation), you can also use “涮†or use terminal blocks; the coaxial cable connection of the TV antenna is best. With a splitter or junction box, the telephone line is similar to a TV line.
2. There is no casing for the concealed wiring. The bushing is used to protect the concealed circuit from damage. If the bushing is not used or an inappropriate bushing is used, damage to the circuit during construction or in future use will leave you hidden dangers. Prevention Tips: Use concealed PVC wiring on the concealed wiring of the wall. Pay attention to matching the wire number. Minimize ground traces. In case the cable is to be routed on the ground, considering that it will be under pressure for a long time and it will be affected during construction, it is better to use the inner pipe of the water gas pipe to re-arrange the PVC pipe and fix it so that it does not move.
3. The completed line was damaged by subsequent construction. The common ones are: the wall line is interrupted by an electric hammer, and the floor nail gun penetrates the PVC line pipe or sheath line. Preventive techniques: Make a mark on the well-conceived lines to avoid unintentional destruction by the construction personnel in the next process.
4. Distribution lines do not consider different rated wires have different rated currents. “Little Marathon†causes long-term overload of the line itself. The selection of distribution line wires should pay attention to its rated current.
5, all kinds of different lines go the same line. If the television antenna, the telephone line and the distribution line are threaded into the same casing, the reception of the television and the telephone is disturbed. The TV antenna line and the telephone line are respectively taken out of the casing.
6, as much as possible to reduce the unnecessary joints, the use of the appropriate line pipe, all the attention should be paid to the construction of the line. Plumbing series: Common problems include leakage of water pipes, odors in wash basins and vegetable sinks, small water flow in bathtubs, inconvenience in the use of sanitary ware, and so on.
Water pipe laying precautions:
1. The pipelines are arranged reasonably, laid firmly, horizontally and vertically, and the switches and valves are installed neatly, which is flexible and convenient to use.
2. Hidden project, first close after acceptance, on the one hand you know how much to do, on the other hand know how to do it. For example, do not do waterproofing after slotting. After pressure testing (required to hit 8 pressures), whether there is leakage, whether the effluent is unobstructed, and whether the water meter is operating normally. Water supply pipelines and accessories are not strictly connected. These hidden projects cannot cause problems, problems arise, and maintenance is difficult. Therefore, regular companies pay special attention to this piece. They often have specialized hydropower construction teams responsible for installation. Special equipment testing. Some small companies and decoration teams do not have pressure testing equipment, and they often use tap water instead. The quality is difficult to guarantee. The water pipes should use quality products such as Kinder and Pilsa.
3, kitchen, bathroom to do waterproof, to do 24 hours closed water experiment, do not leak can not do. Re-spreading or installing ware breaks the waterproofing to redo. The shower area is 1.8 meters high.
4, the floor of the bathroom should be tilted to the ground drain, so that water can flow into the floor drain, no water.
5, washbasin, vegetable washing pool and other hot and cold water joints should be installed below, left hot right cold.
6, the bathtub drain outlet should be aligned with the mouth of the water, and leave the access hole, not the bottom wall when the tile is the focus of water. (Leave a spare brick 3-5)
