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,

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.

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,

Closed equipment containing gas or liquid and bearing certain pressure, Its range for maximum working pressure is greater than or equal to 0.1 MPa (gauge pressure) gas, liquefied gas and the highest standard of working temperature is higher than or equal to the boiling point of liquid, volume is greater than or equal to 30 l and internal diameter (non circular cross section refer to the section within the largest geometry) greater than or equal to 150 mm stationary containers and containers;

A pressure vessel is a closed device that holds gas or liquid and bears certain pressure. In order to more effectively implement scientific management and safety supervision, the pressure vessels are divided into three types according to working pressure, medium harmfulness and their role in production in the "pressure vessel safety supervision Rules".
