Regardless of whether it is home decoration or tooling, hydropower reform is a very important part! If it is not done well during the renovation, it will bring hidden dangers and inconvenience to the occupants in the later period! Therefore, first-class electricians are reminded at the time of hydropower reform . , we must do the following five key points. Let's take a look at the hydropower transformation precautions! I. Notes on hydropower reform 1. When we hand in the house decoration, we must pay attention to signing the contract, we must first lead the master electrician master plan and fixed point! Then proceed to the budget! Generally if the exceed the cost after the completion is not more than 10%, beyond The budget section is not needed! 2. During the transformation of weak electricity, we must pay attention to the use of shielded cables. Most of the strong and weak electricity are piped from the ground, and strong and weak electricity crossover and close parallelism are very common. If you do not use shielded cables, it will cause some interference to the signal. 3. When hydropower is reformed, PVC pipes are generally used! JDG tubes cannot be used! 4, water pressure test This is the most important point that can not be ignored in the test when the pressure is not less than 0.6 MPa, with 15 minutes of static pressure does not fall back to prevail. It also depends on the smooth flow of water, irrigation testing to prevent water pressure and poor water situation. 5, when installing the socket switch, there is no science to say how many must be installed, all of which can be used according to their own needs! After combining the views of the masters, comprehensive and reasonable layout! II. Acceptance of hydropower hidden projects 1. Acceptance of waterway concealment works: 1 The waterproof coating of the kitchen and bathroom walls in the dark coating conforms to the specifications, and the outer surface of the tank is about 20 mm long. 2 The fixed high and low pipe clamps are used for fixing and fixing. The spacing specification is, for example, that the range of thermal melting point is 150-200 mm, and a fixing point needs to be set; if it is a long waterway, every 600 mm, a fixing point needs to be set; The position of the wall must use steel casing. (3) Professional bridges must be used for the crossing of the same plane. The material should be accurately laid, the pipes should be straight, and the axial distortion should be prohibited. 4Hot and hot water pipes and water and electricity pipes are strictly prohibited to be in the same slot. The vertical and horizontal heights of the exposed elbows of the hot and cold water mixing valve are the same, and the spacing should be about 150 mm; the outlet metal wire plugging should be tight and firm; 5 The pressure test record is perfect, and the pressure is in line with the requirements of the East Easy Management: Stop the pressurization after rising to the specified test pressure of 0.9 MPa, and observe whether the joint is seeped; after the pressure is stabilized, the pressure drop within 60 minutes is not more than 0.05 MPa. (National Standard: Test The pressure should be 1.5 times the working pressure and not less than 0.6 MPa). 2. Circuit concealment project acceptance: 1 Use the marble machine to slot, the edges are neat; fixed and use the matching high and low pipe clamps to securely secure, spacing and specification, and it is forbidden to rely on external force to achieve the purpose of viewing and using function; the connection between the casing and the Luokou guard mouth are firmly connected; The bend angle of the 2-wire tube should be >90°, and wrinkles and dead bends are not allowed. 3 wire color separation, and use dedicated WOGO connector; 4 Strict implementation of the "electricity in the water, the water in the next" standard operations; 5 The horizontal distance between water and gas is ≥300mm and the crossover is more than 100mm; 6 Insulated conductors must be matched with hard casing protection, and the reserved lines on the top should be protected by corrugated hoses. The bare wire ends must be protected by wire connectors; the reserved wires should be spiraled; the spacing between strong and weak wires should meet the requirements of the specification; Tube interference with anti-jamming tin foil package. The above is the notice for hydropower reform brought by everyone and the method of acceptance inspection for hydropower concealed projects. After reading this, is there any more understanding of hydropower reform ? Hopefully it can help everyone.
