Fire constant pressure water supply equipment is a new type of variable frequency constant pressure water supply equipment, consisting of three parts: water pump unit control equipment and pressure boosting and stabilizing equipment. The water supply capacity is determined by the water pump unit, and the coordinated operation of the system is controlled by the control system. The main function of the pressure boosting and stabilizing equipment is to store energy to cope with small water supply and normal pipeline leakage. It is also an indispensable part of automatic control. When a large amount of water is used, the network pressure drops, and the water pump automatically starts to supply water.

Fire constant pressure water supply equipment is a new type of variable frequency constant pressure water supply equipment, consisting of three main parts: water pump unit control equipment and pressure boosting and stabilizing equipment. The water supply capacity is determined by the pump unit, and the coordinated operation of the system is controlled by the control system. The main function of the boosting and stabilizing equipment is to store energy and maintain pressure, cope with small amounts of water supply and normal pipeline leaks, and is also an indispensable part of implementing automatic control. When a large amount of water is used, the pressure in the pipeline decreases and the water pump automatically starts to supply water.

1. The fire constant pressure water supply equipment fully absorbs the application design experience of fire water supply equipment in recent years. The entire product is specially designed and manufactured by our company in strict accordance with the GA30.2-2002 standard, and is a mature and standardized product with industry advantages.
2. The supporting electrical control cabinet of the fire constant pressure water supply equipment adopts domestic and international high-quality branded electrical appliances, ensuring the safety and reliability of the product. This product has high cost-effectiveness and is an ideal fire water supply equipment.
3. The fire constant pressure water supply equipment has two functions in control: manual and automatic. When operated manually, it can test the operating status of each fire pump.
4. The fire constant pressure water supply equipment has complete and reliable fault protection and alarm functions. The control system has short circuit, overcurrent, phase failure, and phase sequence protection functions. The PLC can detect motor faults and insufficient water supply capacity of the fire pump, and provide alarm signals. It can also achieve automatic inspection at fixed intervals, accept and process various fire signals, and remotely transmit fire operation condition signals to the fire control center.
5. The fire constant pressure water supply equipment has an advanced and reliable control system, using precise electric valve devices combined with electric contact pressure gauges or remote pressure gauges, controlled by a programmable logic controller (PLC), to ensure that the fire pipe network supplies water at a constant pressure.

Fire constant pressure water supply equipment can be divided into air pressure automatic water supply equipment and variable frequency adjusted constant pressure water supply equipment according to different working modes, each with its own characteristics. Widely used in various fields such as daily life, fire protection, production, and sprinkler systems. According to the different working modes of the equipment, it can be divided into living type, fire-fighting type, sprinkler type, and shared models for living and fire-fighting.

According to different working modes, it can be divided into pneumatic automatic water supply equipment and variable frequency adjustable constant pressure water supply equipment, each with its own characteristics, widely used in various fields such as life, fire protection, production, sprinkler, etc. The water pump is the foundation of the water supply equipment and the fundamental guarantee for the water supply equipment to demonstrate its water supply capacity. The water pump matched with the water supply equipment is universal and can be of various flow rates and suitable lifting programs. According to the flow rate and lifting program requirements, the product can have 1-4 or more water pumps running in parallel. The water pump unit is connected to another set of boosting and stabilizing power supply pressure equipment (water flow pump unit) as a switching operation with the main pump in a small flow range to provide efficiency and further reduce energy.

According to the different working modes of the equipment, it can be divided into living type, fire protection type, sprinkler type, and shared model for living fire protection.

The basic basis for choosing a set of fire constant pressure water supply equipment is the designed water supply flow rate and water supply pressure (water head), and also needs to consider the type of flow variation of the purpose Continuous type - rarely when the flow rate is zero, or when the normal leakage of the pipeline network maintains a certain flow rate, such as in the pressurization system of large hotels, restaurants, industrial and mining enterprises Intermittent type - Water consumption has a long period of low valley time and low or zero flow rate, for example, small office buildings, office buildings, commercial and residential buildings, various residential buildings, and production water use. At the same time, various factors such as changes in flow rate during a certain period of water supply, changes in flow rate in different seasons, and differences in water use in different regions should also be considered Fire water supply equipment and sprinkler water supply equipment should generally choose pneumatic water supply equipment, as it is in a long-term system pressure holding state with no flow rate changes. Pneumatic water supply equipment can cope with general leaks and add a small flow auxiliary pump, so there is no need to start the main pump normally, saving energy.
