Fire water supply equipment is mainly composed of municipal water source or fire pool, fire pump, high fire water tank and pressure regulator device, fire pump adapter and pressure regulator device control cabinet, fire pump control cabinet

The flow of the pump, that is, the amount of water, generally should not be selected too large, otherwise it will increase the cost of buying the pump. Should be selected according to need, such as the user family use self-priming pump, flow should be selected as small as possible;

filter (filter) is an indispensable device on the transmission medium pipeline, usually installed in the pressure reducing valve, pressure relief valve, fixed water level valve, square filter other equipment import end equipment. The filter has a certain specification of the filter cartridge,

Precautions for the use of drainage gas storage tanks: 1. The shell of the gas storage tank should avoid external impact or additional pressure, and avoid corrosive materials from contacting the shell or working in corrosive environment;

Gas storage tank pressure above 1m3/1.0mpa is special equipment, gas storage tank refers to the equipment used to store gas, at the same time plays the role of stabilizing the system pressure, according to the different pressure can be divided into high pressure gas storage tank, low pressure gas storage tank, atmospheric pressure gas storage tank.

Compressed air storage tank is one of the most used equipment in the whole compressed air system. It has a simple structure, can play a stable pipe network system pressure, remove some pollutants, and reduce the compressor frequent start and stop, prolong the life of the compressor, reduce energy consumption, is an indispensable part of the compressed air system.

Due to the good corrosion resistance of the stainless steel gas storage tank, it can resist the erosion of the moisture contained in the compressed air, so as to cause secondary pollution to the compressed air, then the quality of the compressed air will be greatly improved. Its service life can reach more than 100 years (generally about 10 years), greatly saving the use cost.

A pressure vessel is a closed device containing a gas or liquid and bearing a certain pressure. Application scope is defined as: (1) maximum working pressure is greater than or equal to 0.1 MPa (pressure) gas, maximum working temperature is higher than or equal to the standard boiling point of the liquefied petroleum gas and liquid,
