Heat exchange station is an important place to achieve heat exchange and distribution in the centralized heating system, and the equipment of heat exchange station mainly includes heat exchanger, circulating pump, make-up pump, water purifier, valve, instrument, etc., the following is an introduction to the function and characteristics of these equipment:
Heat exchanger: Is the core equipment of the heat exchange station, and its function is to achieve heat transfer between the heat medium (such as hot water or steam) and the heated medium (such as water in the secondary network). The common types of heat exchangers include plate heat exchangers, shell and tube heat exchangers, and volumetric heat exchangers, etc.
Circulating pump: Used to drive the water circulation in the secondary network, so that hot water can circulate continuously between the heat exchanger and the user, to achieve the transmission and distribution of heat. The flow rate and head of the circulating pump should be reasonably selected according to the scale, resistance characteristics and other factors of the heating system, so as to ensure the heating effect and the stable operation of the system.
Makeup pump: Used to replenish the water volume lost due to leakage, evaporation, etc., in the heating system, to maintain the stability of the system pressure. The makeup pump is usually controlled by variable frequency, automatically regulating the makeup water flow according to the system pressure, to ensure that the system pressure is within the set range.
Dirt separator: Installed before the inlet of the circulating water pump, it is used to remove solid particles such as impurities, dirt, and rust from the heating medium, preventing these impurities from entering the heat exchanger, water pump and other equipment, causing blockage, wear or corrosion, and ensuring the normal operation and heat transfer effect of the equipment.
Valves: including various types of valves such as shut-off valves, control valves, safety valves, etc.
Shut-off valve: Used to cut off or connect the flow of water in the heating pipeline, facilitating the maintenance and inspection of equipment. Common shut-off valves include gate valves, ball valves, and butterfly valves, etc.
Regulating valve: Used to regulate the flow and pressure of the heating medium to meet the different heating needs of users. The regulating valve usually adopts electric or pneumatic actuator, which can achieve remote control and automatic regulation.
Safety valve: Is a safety protection device for the heating system, when the system pressure exceeds the set value, the safety valve automatically opens to release part of the medium to prevent the system from operating at excessive pressure and ensure the safety of the system.
Instruments: Mainly including thermometers, pressure gauges, flow meters, etc., used to monitor the operating parameters of the heating system, such as temperature, pressure, flow, etc., to provide accurate data for operators to adjust and control the operation state of the heating system in time, and to ensure the heating quality and the safe and stable operation of the system.
Softener equipment: Used to soften the water supplemented into the heating system, removing ions such as calcium and magnesium from the water, preventing scaling in heat exchangers and pipelines, reducing heat transfer efficiency, and affecting the heating effect. Common softener equipment includes ion exchange resin softeners, reverse osmosis softeners, etc.
Distribution box and control cabinet: Used to control and protect various electrical equipment in the heat exchange station, to achieve the functions of equipment startup, shutdown, adjustment and fault alarm, etc. The control cabinet usually adopts automated control system, which can achieve remote monitoring and intelligent management, and improve the operation and management efficiency of the heat exchange station.
The above is the composition and function of the heat exchange station equipment. It is hoped that the above information will help everyone to further understand the heat exchange station equipment, and through reasonable installation and application, give full play to the market value of the heat exchange station equipment.
