Pressure Setting in Water Systems

Pressure setting equipment is used to stabilise the water system at a defined pressure level to prevent vaporisation and overpressure in the system. Commonly used pressure setting equipment are expansion tanks, make-up pumps, and pressure setting tanks. These fixed pressure equipment is generally set in the heat source, heat station, refrigeration station and independent water system, its role v principle and calculation method is the same, but the size of the equipment capacity differences.

1、Expansion tank pressure setting

The point of using expansion tanks for pressure setting is that the system pressure is stable and the equipment is simple. The management workload is low. The disadvantage is that the tank should be placed at the highest point of the system, occupying a certain space. The building has to bear the load of the tank and the water. Expansion tanks are a common way of setting pressure in small and medium-sized hot water heating systems and air-conditioning water systems.

2、Charge pump pressure setting

The main equipment for make-up water pumping is the make-up water tank and the make-up water pump. Easy matters, good results, but to limit the number of electrical energy, is currently the main way to set the pressure of the Muantong air-conditioning water system. In recent years with the progress of frequency converter and automatic control technology, configuration of frequency converter governor of the charge water pump pressure fixing method is widely used, Beite in most of the water treatment equipment can be in accordance with customer requirements to increase the frequency converter and control cabinet.

The pneumatic tank is a cylindrical steel pressurised container, which is connected to the dry pipe of the circulating water pump inlet of the heating or air conditioning system to achieve constant pressure.

Pneumatic tank pressure setting

The pneumatic tank is equivalent to a low level closed expansion tank, which regulates the amount of water in the system and achieves constant pressure. The fixed pressure water replenishment device is a new type of water supply equipment that has emerged in recent years. It mainly consists of an expansion tank, a pump, an automatic control cabinet, pipes, valves and monitoring instruments. At present, Beite can supply a full range of products.
