Complete set of fire sprinkler constant pressure water supply equipment

Product introduction of complete set of fire sprinkler constant pressure water supply equipment:
The complete set of fire sprinkler constant pressure water supply equipment consists of three 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.

Product Introduction of Fire Pressure Water Supply Complete Equipment

Automatic water supply equipment is a new type of tower free water supply equipment, consisting of three main parts: 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.
Automatic water supply equipment can be divided into pneumatic automatic water supply equipment and variable frequency adjustable 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.
Water pump is the foundation of water supply equipment and the fundamental guarantee for water supply equipment to demonstrate its water supply capacity. The water pump that is matched with water supply equipment is universal and can be suitable for various flow rates and lifting programs. According to the needs of flow rate and lifting program, 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) to switch operation with the main pump in a small flow range, providing efficiency and further reducing energy.
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.


Selection criteria for constant voltage variable frequency equipment

The basic basis for choosing an automatic 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 for the purpose.
Continuous type: There are rarely times in a day when the flow is zero, or when the normal leakage of the pipeline network maintains a certain flow, such as in the pressurization system of large hotels, restaurants, industrial and mining enterprises.
Intermittent type: Long periods of low water usage and low or zero flow, such as small 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 system pressure maintaining state for a long time without any changes in flow rate. Pneumatic water supply equipment can cope with general pipe leaks and add a small flow auxiliary pump, so there is no need to start the main pump normally, saving energy.
Both variable frequency water supply equipment and pneumatic water supply equipment can be selected for domestic water supply, each with its own advantages.
The advantages of variable frequency water supply equipment are that it can provide constant pressure water supply and the constant pressure value can be adjusted within a certain range. The constant pressure accuracy is generally less than 0.02 MPa. Variable frequency speed regulation is an efficient and energy-saving method, with an average energy saving of 20% compared to typical pneumatic water supply equipment. In addition, the impact current of variable frequency starting is small, and the pump's impact is also small, resulting in low noise during low-speed operation.
The advantages of pneumatic water supply equipment include relatively low cost, simple control system technology, convenient service, and easy maintenance.

The fully automatic variable frequency speed regulation constant pressure fire water supply equipment is designed and developed in accordance with the national fire protection standard "Code for Fire Protection Design of High rise Civil Buildings" and the Ministry of Public Security fire protection standard "Performance Requirements and Test Methods for Fire Pressure Water Supply Equipment". It has excellent performance, advanced technology, and stable and reliable water supply
