1? The layout of other facilities should first consider whether it is floor heating, ceiling, water purification system, backwater system, etc. It should be installed at home, the water heater should be electrically heated or gas heated, and the distribution of hot and cold water pipes is left-cooled or cold and hot left-cooled (generally cold and hot left-cooled), which will have a certain impact on the layout of hydropower. The original water and electricity can't be used any more? Or just do breakpoint conversion? Breakpoint transformation: under the condition that the original cable can meet the general use requirements, it will be slightly increased or shifted according to the position of furniture and so on. ) locate the switch socket at home. The switch socket is not fixed, the socket may not be enough, and the plug-in circuit is chaotic. The bedroom light can be turned off before going out. In addition, pay attention to the position of weak current, and the switch socket should not be blocked. Therefore, attention should be paid to the layout of other facilities when the fixture is reformed.
2? Selection of design materials for hydropower renovation of lamps About materials in hydropower renovation of engineering: the panels of switch sockets and household switch sockets are basically 86-type, that is, the panel size is 86mm? *? 86mm. The amperage of the socket is 10A and 16A, while the two-hole socket is only 10A, so once the two-hole socket is 10A, three hole socket is generally separated and equipped with switches, which is suitable for high-power appliances such as air conditioners and cabinets. It should be noted that the traditional five-hole socket cannot plug in two plugs at the same time, and it is necessary to buy a five-hole socket with a misplaced position or a "large spacing". Water pipes, most of the water pipes used now are ppr pipes, but some developers have made pb pipes in advance. The required pipe diameter should not be less than the original pipe fitting standard to ensure the water output and water supply pressure. Neither hot water pipe nor cold water pipe can be mixed because of their different wall thickness and pressure grade. Hot water pipes are usually indicated in red, and cold water pipes are indicated in green. It is also very helpful to choose the design material of fixture hydropower transformation.
3. There are usually two charging methods for hydropower renovation of fixed equipment. One is based on quantity, material cost and labor cost. In this case, the pit money method is to use more materials? Multiple windings. One is the price, the estimated total price, so the way to make money is less material. Take thread as an example. In the first mode, the pipe can be threaded with one thread and multiple materials. In the second mode, a tube may pass through many wires (the total cross-sectional area of the wires in the conduit shall not exceed the inner diameter of the tube). ? 40% of the area).
Hydropower is a complex project, and every builder has different standards. Let's have a look. You'd better check all the points mentioned above. If you find anything unusual, you must ask the foreman carefully. ?
