Hidden engineering circuit construction specifications and processes

The hidden project is the most attention-free but also the most problematic part of the renovation process. But just like its name, the “hidden” project, many consumers do not understand even though they have done a lot of homework. Among them, the electrical construction in the hidden project is a detailed introduction for everyone, so that hidden projects are no longer “hidden”.

I. Hidden project circuit construction specifications and procedures

Material selection

The purchase of materials is very important. Although the prices of big brands and small brands are not much different, the quality is very different. Magnolia's engineering consultants advise owners to choose mainstream and cost-effective materials in Shanghai. The wires installed by the original developers in the rough room must be checked before confirming that there are no quality problems. In order to ensure the safety of electricity use, the old and new wires must not be mixed.

Hidden engineering circuit construction specifications and processes

Today's PVC pipe generally has two points and four points. If the conditions permit, it is recommended to use 6-in charge, 4-in charge can only wear 1.5 squares of lighting line, a PVC pipe can only wear 3 wires at most. 6 points of pipe can be used to wear 2.5 square wires, and a maximum of only 2.5 square wires can be worn in a PVC pipe.

Editor's note: The choice of distribution box is also very important during electrical construction. The power main circuit breaker shall be installed in the distribution box of each household, and shall be used for overload short-circuit protection and leakage protection. The leakage current shall not exceed 30 mA.

The hydraulic system of medium and small hydraulic Excavator Spare Parts has a clear trend of changing to a variable system. Because the variable system compensates by increasing the flow rate when the pressure is reduced during the operation of the oil pump, the hydraulic pump power is kept constant, that is, the Excavator spare parts equipped with the variable pump can often fully utilize the maximum power of the oil pump. When the external resistance increases, the flow rate is reduced (the speed is reduced), and the digging force is multiplied; a three-circuit hydraulic system is used. Generate three independent work movements that do not affect each other. Achieve power matching with the slewing mechanism. The third pump is switched on in other working motions and becomes the second independent fast motion of the open circuit. In addition, hydraulic technology is commonly used on excavators, creating conditions for the application and promotion of excavators for electronic technology and automatic control technology.
