Product Overview of Fire Pneumatic Water Supply Equipment

The company's series of constant pressure water supply equipment generally consists of three parts. The water supply capacity of the constant pressure water supply equipment is determined by the pump unit, and the coordinated operation of the system is controlled by the control cabinet. The main function of the air pressure accumulator is to store energy and maintain pressure, cope with a small amount of water supply and normal leakage, and is also an indispensable part of automatic control. When a large amount of water is used, the pressure of the pipe network drops, and the water pump automatically starts to supply water. To be precise, the water supply equipment without the energy accumulator is a set of pumping station equipment that automatically adjusts the pressure and flow, and generally cannot be automatically turned on and off. There are two kinds of air pressure accumulators with their own characteristics, one is the diaphragm air pressure tank, the compressed gas and the water are separated by the diaphragm and do not contact during operation, so that the gas volume can be maintained for a long time without reducing. The other is the automatic gas supply tank, which continuously and freely supplies gas during operation to supplement the reduction of gas leakage due to dissolution. There are more than 7-8 ways of supplementing qi since the previous practical application.

Due to the different working characteristics, constant pressure water supply equipment is divided into two categories, one is called air pressure automatic water supply equipment, and the other is called frequency conversion speed regulation automatic water supply equipment. They have their own characteristics, all belong to the tower-free water supply equipment, and have been widely used in many fields such as P&G, production, fire water supply, water hammer and so on.

According to the needs of flow and head, the product can be equipped with 1-4 or more pumps to run in parallel. If only one pump is assigned, it is called the base pump or the main pump, and the other is called the auxiliary pump. When the flow demand is small, only the base pump is turned on, and when the flow demand is large, one or more auxiliary pumps are started. According to the different control procedures, you can choose the vertical operation mode in which the base pump is fixed and the auxiliary pumps are automatically alternately alternated, or the operation mode in which the basic pump and auxiliary pumps are alternately alternated at the same time (each pump is both the base pump , is also a catch pump), in case the standby pump is not used for a long time and rusts and gets stuck.

Product Features of Fire Pneumatic Water Supply Equipment

1. Automatic speed regulation and constant pressure water supply, the water supply pressure can be adjusted in an appropriate range according to needs, and is not limited by the parameters of the pump series;

2. It can prevent accidents such as high-pressure pipe burst caused by the pump running at a small flow rate;

3. It can realize the function of low-speed inspection and test machine of fire pump;

4. The frequency converter has a perfect detection function, and the soft start and soft shutdown of frequency conversion have little impact and have high start-up reliability;

5. It can realize a set of equipment for fire fighting, living and production, multi-constant pressure water supply, and automatic control;

6. Equipped with a communication interface (RS485 free port) to interface with the building BA system to realize networking;

7. High starting point and high reliability design, absorbing the application design experience of variable frequency constant pressure water supply equipment in the past ten years, and optimizing the control system scheme and main circuit switchgear.

Product use of fire-fighting pneumatic water supply equipment

It is suitable for the occasions where the water source of the municipal pipe network is directly extracted for the fire water supply; it is suitable for the occasions where a set of water supply equipment is used for living and fire fighting; it is suitable for the occasions where there are special requirements for the fire water supply pressure, fire inspection and other aspects; it can improve the fire protection Practical use of water.
