For the owner's demand for hydropower, the designer should consider the order of safety → environmental protection → energy conservation → practical → effectiveness in accordance with the specific conditions of the house, to meet the owner's needs to the maximum, but not to meet the owner's needs unconditionally. . Specific attention to the following points: 1, the owner requires the relationship between the total power consumption and the total power load of the house. With the continuous improvement of people's living standards, the total capacity of household appliances is getting larger and larger, while the original design capacity of some houses is generally constant, and some old homes have a small design capacity. 2. The effect of the owner’s required hydropower pipeline on the structure of the house or the entire hydropower system. Hydropower pipelines play an important role in the function of the house. Some owners, in order to pursue functions, but also do not understand the structure of the house and the entire hydropower system, can easily request some influence on the structure of the house and the entire hydropower system. 3. Whether the effect required by the owner is the same as the actual use effect after completion. Since the owners do not understand the decoration generally, it is impossible to consider the overall layout of the house when making the request. It may not be reasonable to consider some of the requirements that appear to be good on the whole. In addition, with the application of new technologies and new materials in the home improvement of water and electricity, those technologies and materials that are inadequate in terms of safety, environmental protection, and energy saving are gradually being eliminated. Designers should always pay attention to changes in this area. For example, the distribution system changed from the original three-phase four-wire system to three-phase five-wire system, energy-saving lamps should be widely used in the home, the Ministry of Construction to promote the application of energy-saving environmental protection and drainage materials and sanitary ware. The circuit should be designed with accurate position, reasonable control and moderate illumination. At present, there are many electrical appliances in the home, and the position of the outlet connected to each appliance must be calculated accurately when it is designed. Otherwise, it is not easy to expose the end of the socket and it is not safe; the control of the circuit should be reasonable. For example, the living room chandeliers adopt sub-control switches and the stairs adopt dual control. Switches, etc., not only save energy, but also economical and practical; indoor lighting to moderate, too dark, bad vision, too bright, causing light pollution, and wasting energy. The construction of hydropower should be cautious. The management of materials in the building materials market is not standardized. Do not plan to purchase electricity, water, electricity, water, electricity, water supply, etc., and don’t plan to purchase electricity. In order to purchase regular products, you must carefully inspect the product's production license and business license. , test reports, 3C certification and other information is complete, and to open an official invoice. In the hydropower construction process, the following points are mainly noted: 1. Do not damage the original wire piping or plumbing piping when grooving or drilling. When the electrical conduit is laid, it is necessary to thread the conduit. Do not bury the wire directly on the ground or in the wall. This is not only unsafe, but it cannot be repaired once it is damaged. After the plumbing pipe is applied, the plumbing pipe must be pressure tested. After the pipe is qualified, the next process is performed to prevent the pipe from leaking and causing damage. 2, the kitchen and bathroom, etc. need to do waterproof parts, after the completion of the water must be closed water test, after passing qualifying. 3, wire connectors must be tinned, kitchen and bathroom fittings recommended to do waterproofing, joints can be used high-pressure self-adhesive tape and black tape for dressing. 4. Lamps with a weight of more than 3 kilograms must be fixed on bolts or embedded hooks. It is forbidden to use wooden wedges to fix them; the metal shell of lamps with installation height less than 2.4 meters must be protected grounded, and the toilet must use waterproof sockets. Hydropower construction mainly pays attention to four aspects. 1, the design should be reasonable. The direction of the water circuit should be reasonable, safe, practical and protective. 2, the material to be qualified. Hydropower materials should be regular brand products. 3, construction should be standardized. All wires must be piped, elbows must be used at the joints, and the ground must be handled as specified. 4, acceptance should be rigorous. All hydropower construction techniques must be in place and meet the construction specifications. Circuit construction must be standardized, for example, the diameter of 16mm line pipe wears up to 3 lines; strong and weak wires to distance more than 50cm, to avoid signal interference; concealed line tube to be fixed firmly, otherwise the wall is easy to crack. The acceptance check of hydropower should be meticulous . The acceptance inspection of hydropower projects mainly includes the inspection during the construction process and the inspection of the delivery. Check during construction. For those processes that will have a serious impact on the entire process if the construction fails, it must be checked after it is completed. Such as kitchen and bathroom waterproof, buried underground water and electricity pipelines, after the construction of the floor tiles found that water is not qualified, the wiring pipeline is not connected, plumbing pipeline is not connected or water leakage, it can only be reworked. There are six main contents of inspections. 1. The wire conduit should be unblocked, and the conduit wire should be drawn back and forth by hand. It should be able to twitch so that the damaged wire can be replaced later. 2. Check the socket wire sequence with the electric pen or socket detector. It must be left zero and right fire on the ground. 3. Check the switch wire sequence with the electric pen. The switch must control the fire wire. 4. Check the test button of the leakage protector or check the leakage protector with the socket detector. The operation must be flexible. 5, using the insulation resistance meter to detect the insulation resistance of the loop is not less than 0.5M ohms. 6, open the main valve, hand touch to the drainage pipe joints to be tight, no water leakage, drainage should be smooth. Acceptance inspection must pay attention to the preservation of the water circuit construction drawings, and require the drawings and the actual to be consistent with each other, because the drawings are the basis for future maintenance, but now most owners ignore this.
