How to accept hydropower, and whether there is a senior hydropower supervisor

1. When accepting, not only the construction party or the supervisor can be present, but the construction party, the owner and the supervisor must be present at the same time to accept the water and electricity of the home, and the owner can sign the next step of construction after passing the acceptance.

2. Acceptance tools are generally prepared by the supervision or construction party, including pressure test pumps, flow wrenches, raw material belts, plugs, jacks, pressure gauges, water tanks, connecting hoses, ammeters, etc., the owner can bring their own tape measure, small notebook, small flashlight, etc., to facilitate the measurement and recording of various data on site.

3. In addition to the acceptance of waterways and circuits, the acceptance can also be divided into material acceptance, wiring inspection, voltage test inspection and other project acceptance. Let's take a look at how to do the acceptance step by step.

4. Material acceptance includes pipeline inspection of waterways and circuits, and whether the materials and lists belong to the same brand and model; whether the line pipe is damaged; length of use, etc. The wiring inspection must see whether the wiring of the clear water circuit meets the specifications, including the distance, location, and direction of the water pipes, as well as the distribution of wires. Suppression and electrical test inspection, the waterway inspection must be carried out to suppress the water test, and the circuit inspection needs to use the ammeter to test whether there is a problem in each channel.

Finally, there is the inspection of other details, such as the condition of the drainage pipe, the slope of the drainage, the location of the wire box, etc.

Precautions for the acceptance of water and electricity in new houses.

1. It is taboo to bend and bend in hydropower transformation. Generally, when laying line water pipes, we should try to pursue vertical, and if it is really not possible to bend, we should also install a junction box in the middle, which is an important one of the precautions for hydropower acceptance.

2. Don't forget to do the suppression test and water seepage test. In the process of hydropower acceptance, we should conduct pressure tests and water seepage tests on water pipes and drainage pipes respectively.

3. The leakage test is very important when accepting hydropower, which has the most direct impact on our life safety.

The acceptance of water and electricity decoration is very cumbersome, and there are many things to pay attention to, so we must calm down and check it well, only in this way will there be no mistakes! Of course, if you want the hydropower transformation to be successful, in addition to the acceptance to give the accident, the supervision during the construction is also sloppy.

As the saying goes, "If you don't accept it after completion, all the decoration will be done in vain". Therefore, we can see the importance of supervising the acceptance of the project.

So, what are the deficit items inspected by the supervision and acceptance project? What are the criteria? Below, I will explain the details of supervision and acceptance from the part of hydropower acceptance.

1. Supervise and accept the waterway.

1. First of all, the easiest step, open the faucets everywhere to check how the water quality is. If there is rust on the valve, then part of the water pipe needs to be replaced; The interfaces between the faucet and the water pipe should also be checked for leakage and blockage. During the whole inspection process, the water outlet can be larger, so that the water pressure and drainage speed can be tested by the way.

2. Check the water meter. Check whether the water meter will be empty when the water is closed again, and of course, the valve tightness. If there is an empty phenomenon, it means that there is a water leak somewhere, which should be investigated section by section.

3. If the outer diameter of the water pipe is less than 25mm, the pipe clamp needs to be set up during installation, which is to avoid the bending of the water pipe under bad pressure when the water pressure is large. Generally speaking, it is fixed with a pipe clamp at 100mm of the angle valve.

4. The connection of all pipeline joints and valves must be tight, and no leakage is allowed, and it is recommended to set a little slope for long-term use of the pipeline.

5. Different specifications of pipes have different functions. For hot water pipes, it is recommended that you use PPR pipes; If you have cold water, it is recommended to use PVC pipes. If it is a PPR pipe with hot melt process, there is no problem to go to the ground; If you want to use the silk mouth process, you must go to the roof.

6. When installing hot and cold water pipes, the hot water pipes are installed above the cold water pipes horizontally; Vertically, the hot water pipe on the left and the cold water pipe on the right. The distance between the two tubes is controlled by about 15 cm.

2. Supervise and accept the circuit.

1. First of all, use an electric pen to detect whether the panel of the socket is live. Switches, sockets and main switches throughout the house can be tested, and the detection method is also very simple. You only need to turn on and off the lights several times frequently, and the socket can see the power on and wiring, 2. Power off test.

Generally, the main electric gate of the commercial house is around the entrance door, what we want to check is whether the circuit and socket are completely powered off in the state of pulling the gate, and if there is leakage, it can be checked by powering off the power district by area.

3. Check whether the use of the meter is normal. When the meter is installed, it is generally 10A single-phase electricity. If the current is unstable, it should be repaired in time.

4. Look at the wiring. Wiring is the most important step in the acceptance of the circuit, and the direction must be clear and reasonable, so as to avoid the occurrence of electrical accidents before the pinning. And all wires must be threaded through PVC pipes.

The owner must let the supervisor put more snacks on this piece, they are hidden projects, and it will be too late to find out after the decoration!

1.Check the hydropower laying lines.

Compare the construction drawings to see if there is any laying of water and electricity pipelines according to the lines on the drawings, and the construction drawings must correspond to the actual site conditions, so as to avoid bursting the water pipes when drilling on the ground or wall after the pipeline is buried in the later stage.

2.Acceptance of hydropower materials.

Compare the decoration contract, check whether the brand and model of the wire and water pipe are consistent, and if the materials are found to be inconsistent, ask the decoration company to replace the materials.

3.Power on and water.

When the water pipe and the wire pipe overlap, the wire pipe should be placed on the water pipe to avoid the water pipe leakage will affect the wire and cause potential safety hazards. There is no joint in the conduit, and the wire should be a loose wire, which is convenient for later maintenance and replacement.

4.Socket potential check.

Check whether the number and position of the water and electricity switches are consistent with those on the design drawings.

5.Circuit acceptance.

First, check whether the wiring of the electrical box is reasonable, whether the main switch of the home circuit is clearly classified, and do not use the same leakage switch for the whole house circuit.

Strong current acceptance: 500V insulation resistance meter is used to test the insulation resistance value of each circuit, and the insulation resistance value of each circuit is generally not less than a megaohm for normal.

Weak current acceptance: test whether the 8-core signal of the network is smooth and whether there is an incorrect connection.

6.Waterway acceptance and pressure test water.

The pressure test is to check the impact of water pressure on water pipes and other materials, and to ensure the performance of water pipes and the tightness of their installation.

7.Sewer deodorization treatment.

Most of the peculiar smells in the kitchen and bathroom are not done well in the trap to prevent odors, and if they are not installed, they should be rectified by the decoration company.

Hydropower acceptance is the process of checking and confirming whether the hydropower system meets the relevant standards and specifications after the renovation or construction of the house is completed. The following are the general water and electricity limb spring acceptance steps and precautions:

Check the hydropower engineering drawings: Before acceptance, check the hydropower engineering drawings to confirm whether the installation location and wiring meet the design requirements.

Check the wires and trunking: Check whether the wires are properly laid, whether the joints are firm, and whether the trunking that meets the specifications is used.

Check the sockets and switches: Check whether the sockets and switches are firmly installed, whether the wiring is correct, and whether they meet the safety requirements.

Check the fixtures and lighting system: Check that the fixtures are installed securely, the bulbs meet the specifications, and the lighting system is functioning properly.

Check the water pipes and valves: check whether the water pipes are installed correctly, whether there is leakage, and whether the valves are opened and closed normally.

When the new house is accepted, water and electricity are one of the important contents, because it is related to the safety of electricity. How to accept hydropower? Let's take a look.

1. Water acceptance process.

1. Pressure test. 1) Open the water inlet valve, slowly fill the water from the lowest outlet of the pipeline, fully discharge the gas in the pipeline, and tighten the pressure test pump switch.

2) Close the main water inlet valve, slowly increase the pressure of the pipeline, and observe whether the joint and plug leak after the pressure is raised to the specified test pressure.

3) Welded pipes such as PPR, aluminum-plastic PPR, and steel-plastic PPR should be kept for more than 30 minutes, and non-welded pipes such as aluminum-plastic pipes and galvanized pipes should be kept for 4 hours. At the end of the test time, the pressure drop does not exceed that to pass.

2. Water pressure relief.

After confirming that the pressure test is qualified, connect the pipe end to the water distribution parts, supply water at the working pressure, open the water distribution parts in batches, and test whether the water outlets are unblocked.

Second, the electrical acceptance process.

1. Inspection. Check whether the intercom and emergency call button of the house are normal, whether the doorbell is normal, the safety of the safety socket, the number and safety of the TV broadband socket, including the bathroom, kitchen, living room, bedroom, etc.

2. The safety of the electrical circuit switch box.

The safety and convenience of electrical circuits, according to the regulations, the number of residential circuits in each set should not be less than 5, the switch in the switch box is installed firmly, can be changed to check, whether there is looseness. Each branch switch in the switch box should be clearly marked. If it is not clear or unclear, it is corrected immediately during the renovation.

3. The electric pen tests the socket panel.

Use an electric pen to test whether there is a point in the plugging of the leather seat panel, whether there is a problem with all the switches, sockets and main electric valves in the house, pull the socket switch in the middle and lower main switch box, the indicator light is off, and frequent testing several times proves that the switch, the wiring is good, and the socket is safe.

4. Pull valve power-off test.

If the switch and meter are outdoors, check whether they can control the indoor lamps and sockets indoors, and whether the indoor power is completely cut off after the switch is pulled; If there are openings indoors, they should also check whether each branch line is fully controlled separately.

5. Check whether the meter is powered on.

At present, the installation of electricity meters is mostly 10 (40)A single-phase energy meters, and whether the operation is normal. Fast or slow should be reported for repair. The number of meters used because during construction, workers may be using your energy, and the money should not be paid by the owner.

<> "How to Conduct Acceptance of Hydropower.

Everyone should understand that it is very important for us to rent water and electricity, and he has a lot to do with the comfort and safety of home life in the future. So, how to carry out the acceptance of hydropower? Today, I will take you to learn more about it.

1. Preparation.

Hydropower acceptance is related to safety issues, so certain tools are needed during acceptance, such as electric pens, simple pressure testing tools, etc., including pressure pumps, wrenches and other tools, everyone needs to be ready, and it will be more convenient when accepting.

2. Waterway acceptance.

The acceptance of the waterway should first test the pressure of the water pipe to ensure that the water flow can flow normally, and then check whether the hot and cold water pipes, valves and the layout of each space of the water pipe are reasonable, so that it will be convenient when it is used. Finally, the hot and cold water pipes should be hot on the left and cold on the right, and the color of the water pipes should be different, so that it is easy to distinguish them when they are repaired in the future.

3. Circuit acceptance.

Compared with the acceptance of the waterway, the circuit is more complicated, after all, it involves a much wider range. The circuit is accepted to see if the location of the socket and lamp in the house meets the needs we want, and it is too high and too low will affect the convenience of our use. In addition, the strong and weak conduits in the circuit should be seen to see if they are separated, and the colors should also be distinguished.

Finally, when accepting, see if there is a problem with the light switch in the house, pull down the switch to see if the indicator light is off, and if there is a problem, you must respond in time.

4. Acceptance of detailed circuits.

Like the doorbell in the house, the light strip of this acre of some details of the circuit, we have to see if there is no circuit in advance, don't wait for the later stage to install Xunqiao old these things can't be helped, after pulling the circuit, we also have to use a voltage detector to check whether it is energized.
