Anonymous users2024-02-08What are the basic knowledge of plumbers.
1. Before construction, be sure to make layout drawings for electrical, water supply and drainage;
2. It is forbidden to lay wires directly in the wall, in the floor and on the ceiling;
3. The installation of lamps and lanterns should be carried out after the painting is completed;
4. Lines with different voltages, different circuits, and different signals are strictly forbidden to wear in the same conduit;
5. The switch of lamps and electrical equipment must be installed on the "phase wire";
6. It is forbidden to use the mobile switch at the head of the bed;
7. The interface of each line should be smooth and the connecting plate should be firm;
8. The water supply pipe can be PP-R pipe, copper pipe, etc.;
9. The installation position of sanitary appliances should be accurate, and the installation of supports and brackets should be smooth and firm;
10. The conduit should be selected with qualified products, not only that the soup wire can be penetrated, but also that there should be enough clearance to dissipate the heat generated when passing through a large current.
11. For the water supply pipeline, it is necessary to strictly test whether each part is connected tightly and firmly, and whether the direction is correct, and at the same time, the water pressure test must be done before it can be buried after testing the water for a period of time. The pressure test index is generally suitable.
12. The cross-section of the drainage pipe should have sufficient slope, and the connection between the various periods should be tight to ensure that there is no leakage.

Anonymous users2024-02-071. Before construction, there must be electrical, water supply and drainage design and construction drawings.
2. It is strictly forbidden to lay the wire directly in the wall, on the floor, under the floor or on the ceiling without any protection.
3. Lines with different voltages, different circuits, and different signals are strictly forbidden to wear in the same conduit.
4. The installation of lamps and lanterns should be carried out after the painting is completed. Install lamps and lanterns on the brick-concrete structure, it is strictly forbidden to use wooden wedges, and use hooks, bolts or expansion bolts. There should be no less than 2 bolts to secure the fixture. Tung field lamps shall not be installed on combustible components.
5. The opening and closing of the lamp and electrical equipment must be installed on the "phase line", otherwise after the switch is dropped, the lamp off and the electrical equipment will still be live, which is easy to cause electric shock.
6. There are two power systems.

Anonymous users2024-02-05The installation of water and electricity is part of the basic decoration, and it is a hidden project belonging to the living room, so it must be paid attention to when decorating. When we decorate water and electricity, we must first understand, so that we will not be blind when we supervise the staff, so let's understand the basic knowledge of water and electricity installation.
1. The pipeline of the water pipe is slotted, before the slotting, we must first play the line according to the drawings, the general regular pipeline slotting route is generally parallel or perpendicular, the pipeline of the flat walking line is generally controlled at 60-90cm high, and the pipeline on the wall must be vertical, and the depth is controlled at 4cm.
2. Waterway pipeline installation, most of the current decoration is the use of PPR pipes, the pipes are divided into cold water pipes and hot water pipes, and the hidden pipes cannot use galvanized iron pipes, and the construction personnel should inform the owner to discuss the location of the water area.
3. The supervision of the waterway pipeline, the supervision of the waterway pipeline is very important, which is related to the potential safety hazards in the future.
4. Conduit, when wiring the circuit, the conduit should be used, because the wire can not be crowded with the conduit, we must reserve enough space, the wire will generate heat when passing through the high current, if the conduit is too crowded, the heat is difficult to dissipate, which will lead to safety problems.
5. It is forbidden to connect wires in the conduit, and there can be no wiring in the conduit. It is one of the most basic basic knowledge of hydropower installation, so when decorating, it is necessary to avoid the joints of the wires, and generally wire in the junction box in the switch, socket and lamphead box.
After moving in later, it is very troublesome if there is a problem with water and electricity decoration. Therefore, it is still necessary to check the water and electricity in the early stage.
It is a small "rigid wire". The wire is too soft,,, head is bent by hand "pliers", bent a little more, "I don't know what to type for you, you can't tell me?? People turn high hydropower", skills,,, if you can't wear it, turn the wire a few times, turn the hand with a little force to wear, "the wire is small but if you want it to turn, yes, hold the main wire about 15-20cm with both hands, if you can't turn it,, bolt I didn't say", wire and wire joint, steel wire head bend 360 degrees, use pliers to pliers, don't be too big, first tie a wire to go, tie other wires on this wire, the text is not easy to describe, I can't understand it, I can't ,,, pull the wire, so I use pliers to clamp the master, eat a full meal, and pull the ......, the force is small and there are two, not enough to add people,,, but ......Be careful,,, don't pull the wire off,,, then pull it white. >>>More
