What do you need to know if you want to learn about hydropower installation? 5

You have to know a little bit about everything, because plumbers are similar to generalists, requiring you to be knowledgeable but not proficient, for example, plumbers, electricians, painters, carpenters, masons, welders have a point, it is recommended that you buy an electrician primer to read.

Communicate with people. Ability to work collaboratively with others.

Basic knowledge of hydropower.

What are the basic common sense of hydropower installation? What issues need to be paid attention to in hydropower installation? The necessity of water and electricity decoration is needless to say, it not only affects the convenience of daily life in the future, but also relates to the safety of the owner's home, especially the circuit installation, people first look at the common problems of circuit installation:

All household appliances control lines and routes must wear PVC pipes. , the route goes from the wall. The same power circuit cable should be laid in the same pipeline, the cable diameter should be appropriate, and the number of conduits should ensure that the cross-sectional area of the pipe shall not exceed 40% of the cross-sectional area of the PVC pipe.

The bending degree of the cable should not exceed 90 degrees, and the pipe should be connected when it exceeds 90 degrees. When the wire is threaded, the height must be separated, and all the wires are threaded. The connector is sturdy and reliable, and the insulation performance can be excellent (the resistance value is exceeded.

Reasonable layout of the route. The fixed position of the socket switch must meet the regulations, that is, the power switch is 1200-1300mm from the ground, and the power socket is 300-450mm from the ground. The direction of each line is clear and orderly.

When designing the waterway, we should first consider what are the tap water appliances, such as: electric water heaters, clothes machines, toilets, washbasins, kitchen sinks, etc., and they should be placed in the first place, what is the installation method, and whether it is necessary to boil water.

In order to prevent repeated renovation of the waterway, it is necessary to make it clear before the design plan that natural gas or household water heater is used for bathing. In addition to the washbasin, cloth basin, toilet, clothes machine, etc., the part of the embedded drainage outlet in the bathroom also needs to be connected to one more to go out, and it is convenient to connect the washing ground. After clarifying the location of the washing machine, you can choose to ensure the drainage pipe of the washing machine to the inside of the wall, which is more beautiful and generous.

After the renovation of water and electricity, the irrigation test should be done. The connections of all water pipes should be strong, reliable, and have better sealing characteristics. When handing over the restaurant, kitchen, bathroom water outlet to check to see whether the water flow is normal, such as slow water discharge should immediately let the property company through, decoration will carry out maintenance on the water outlet, to prevent the floor tile parquet concrete falling into the water outlet caused by blockage.

1.Before construction, there must be electrical water supply and drainage design and construction drawings, so as to facilitate the later acceptance. It is also necessary to pay attention to the acceptance after the hydropower transformation, taking into account that the height of the cassette should be on the same horizontal line, and it cannot be tilted inside and out, otherwise it will conflict with other positions.

2.A certain size should be selected for the threading pipe. For example, the thickness should allow the wire to penetrate in, and there must be enough space to dissipate all the heat generated by the wire when passing through the high current, and it is strictly forbidden for the wire to block the wire pipe.

3.Different voltages should have different circuits, and it is strictly forbidden to wear lines with different signals in another line pipe, and it is strictly forbidden to intersperse wires directly on the ground without protective measures, such as in the wall, in the floor, under the floor or on the ceiling.

4.The interface of each line should be smooth, and the connecting plate connection should be firm. The interface box of the power supply inlet box should be protected by a protective ring (lock nut).

Basic common sense: The design of the circuit section must be determined after careful consideration of the possibility, feasibility, and usability. No one wants a room full of wires, and circuit design should be flexible.

Attention problems: 1. Acceptance of hydropower materials Acceptance of hydropower materials* is planned to be carried out immediately after the materials arrive at the site. Therefore, it is very necessary to agree on the acceptance time so as not to affect the construction progress.

2.Water before electricity The order of installation works is to discharge the water pipe first, and then discharge the wire pipe. In addition to meeting the functional requirements, the process arrangement in this way also takes into account the difficulty of construction.

It is important to pay attention to one point, the simplest installation method, but also to pay attention to the arrangement and combination, but also to pay attention to the conversion of the pipeline, but also to pay attention to the quality, but also to pay attention to the signs of installation. Pay attention to the layout, but also pay attention to the style, but also pay attention to the quality, but also pay attention to the environmental treatment, but also pay attention to the launch, pay attention to the time problem.

To put it bluntly, hydropower engineering is a technical job and a university question. Hydropower installation is a very important part of home decoration, which is directly related to the potential safety hazards of the family, so we must have a detailed understanding of the basic knowledge of hydropower installation before doing hydropower installation. Doing a good job of family protection measures is another way to protect the family without filial piety.

Let's learn the basics of hydropower installation together!

1. Circuit installation.

1. Before the installation of hydropower, it is necessary to mark the electrical appliances (strong and weak current) on the drainage design and construction drawings.

2. Do not directly lay unprotected wires in the wall, in the floor, under the floor or on the ceiling.

3. Lines with different voltages, signals and circuits cannot be worn in the same line tube.

4. The installation of lamps and lanterns must be installed after the completion of paint construction, and the switch of the lamps must be installed on the phase line, otherwise after turning off the lights, the electrical appliances will still have electricity, so it is easy to have electric shock accidents. If the lamp uses a screw head, the center spring of the screw head must be connected to the control phase wire.

5. The wire can not be connected in the conduit, even if the length of the wire is not long enough to be wired, the connector of the wire cannot be in the conduit, and can only be wired in the junction box such as switches, plugs, and light boxes.

6. Generally speaking, the protection power system should be adapted. Grounding protection and zero protection can be taken, but the two protection measures cannot be used at the same time, and grounding protection is usually used.

7. The interface of the line must be smooth, and the connecting plate must be firm enough, and the wire can not block the threading pipe.

Second, the installation of waterways.

1. The electric water heater must have a grounding protection device, which can be powered on and started when it is just started.

2. The horizontal drainage pipe should have a certain slope, and the connection between the sockets must be tight to prevent leakage. Fixed pipe brackets and elevators should be reasonable distance from each other.

3. The direction of the installation of the waterway should be accurate, and the installation of the water pipe must be firm. The equipment that needs to be installed in the restroom should be precisely and firmly positioned.

Hydropower decoration is a very important part of the home installation, the decoration of the householder will also attach great importance to this aspect, I believe that water and electricity in our daily life is very important, for the decoration of water and electricity, there are generally professional installations, because there may be leakage in the future, so it is important to find a professional installer. In order to give everyone a better understandingKnowledge of hydropower installation, Let me introduce to you the installation knowledge of home improvement water and electricity, and the precautions for hydropower installation, as well as the ** of hydropower installation.

One. Knowledge of home improvement water and electricity.

1.When installing water and electricity in the home, it is necessary to sell Huai Huai to dig pipes, one is water pipes, and the other is circuit pipes. When the pipeline is excavated, it is best for the householder to check the quality on the spot, ensure the safety of materials and lines, and prevent cutting corners; In addition, it is not possible to connect wires in the pipeline, and it is necessary to ensure the safety of water and electricity in the future.

2.The pipeline materials for hydropower installation are also very important, and there are many kinds of materials used for water pipes, such as PPR pipe pure core is a commonly used pipeline material, and the installation also needs the on-site supervision of the householder, such as the placement of faucets and sockets, where the sockets are installed, how many are installed, can give the best advice to the installers, and the socket needs to be bought, which is also a part of safety to ensure the practicality and safety of the faucet and socket in the future.

3.After the installation of water and electricity is completed, the householder must check the water and electricity pipelines and lines again, pay attention to the safety of water and electricity in the future, and prevent accidents in water and electricity leakage. For example, check the quality of the water pipes and check for leaks in the joints.

Two. What else to pay attention to in the installation of water and electricity.

1.When installing waterways, think about what equipment needs water. For example, kitchen faucets, bathroom basins, toilets, and electric water heaters used in baths, etc., and think about where to install them so that they can be used later.

2.When decorating and closing the house, pay attention to whether each drain can be used normally, and there will be no slow drainage, especially pay attention to the bathroom and kitchen. And the kitchen drain must be bought large, because the washing of vegetables is relatively slow, and the water flow must be smooth; And the most important point in the bathroom is not to use deep water seal floor drain, so that most of them can't go down the water, because the feature of deep water seal floor drain is that the water is very slow; There is also the toilet installation can be installed with cement without digging, it must be installed with silicone, otherwise it is easy to leak, and the pit distance of the toilet and the flushing volume of the toilet should also be considered.

Three. The cost of water and electricity installation.

Regarding the installation of water and electricity, it is also a problem that many householders are concerned about and think about the most, so I will introduce it to you for your reference. Electricity: network cables, TV cables and socket switches, etc., light switches: 12 yuan, sockets:

When it comes to water and electricity installations, we need to keep the budget under control while maintaining quality.

The above is the knowledge of hydropower installation and the precautions for hydropower installation, and the general situation of hydropower installation, I hope to help the householders who want to decorate.

1. Pre-embedding, installation and commissioning of water supply and drainage pipes, external downpipes, and air-conditioning condenser pipes. Meet the requirements of drawings and specifications, and pass the acceptance.

2. Installation and commissioning of heating projects. Meet the requirements of drawings and specifications, and pass the acceptance.

3. Strong electricity: the embedding, installation and commissioning of the electrical part of the design of the excited paper and the lightning protection and grounding of all drawings and sheds meet the requirements of the drawings and specifications. (Note: It also includes the primary and secondary pre-embedding of weak current, ventilation pipe hole and fire weak current, and ensures that the pipeline is unblocked).

4. The installation and commissioning of weak current threading and bridge frame meet the requirements of the drawings and pass the acceptance.

5. The installation and commissioning of fire lineing, pipelines, chain source temperature, etc., meet the requirements of the drawings and pass the acceptance.

6. The installation and commissioning of ventilation and smoke exhaust shall meet the requirements of drawings and specifications, and the acceptance shall be qualified by the lead bureau.
