How to eliminate the high pressure fault of the cooling water circulation machine

There is a lot of reason for the alarm when the cooling water circulation machine is turned on. Let me introduce the working principle of the cooling water circulation machine.
The cooling water circulation machine is a refrigerant (the refrigerant) that absorbs the heat of the object to be cooled in the evaporator and vaporizes it into steam. The compressor continuously extracts the generated steam from the evaporator and compresses it. The high-temperature and high-pressure steam is sent to the condenser and then condensed into a high-pressure liquid by releasing heat to a cooling medium (such as water, air, etc.), and then enters the evaporator after being depressurized by the throttling mechanism, and vaporizes again to absorb the heat of the object to be cooled, so that it is repeated. Ground cycle. When heating, the refrigerant changes the flow direction of the refrigerant through the four-way valve. The flow direction of the refrigerant is just opposite to that during cooling. The refrigerant first passes through the evaporator, returns to the condenser, and finally returns to the compressor.

The reason for the high-pressure alarm of the cooling water circulation machine is as follows: the parameters are not set well: the reason is that the manufacturer has not tested the machine or damaged it during transportation.

The reason for the high pressure alarm of the cooling water circulation machine is that the pressure controller of the cooling water circulation machine is broken. The pressure controllers used by the manufacturers of the cooling water circulation machines are different. Some manufacturers use electronic pressure controllers, which have small advantages and low prices. . Disadvantages: When the high temperature is too high, it is easy to burn out.

The reason for the high-pressure alarm of the cooling water circulation machine is three : air-cooled cooling water circulation machine, there are obstructions around to block the ventilation, and the machine should be placed in a place with good ventilation effect. If it is running for a period of time, consider whether the wind network has gray. The layer needs cleaning at this time.

The reason for the high-pressure alarm of the cooling water circulation machine is four : the water-cooled cooling water circulation machine adopts a shell-and-tube condenser. It is connected to a cooling tower (cold water tower) for cooling. The cause of the high-pressure alarm: the cooling tower has no water, the cooling tower fan is broken, and the cooling tower pipeline is blocked due to long-term use. The shell-and-tube condenser is used for a long time, the internal pipeline of the condenser is blocked, or the cooling tower is small. The condenser is equipped with a small heat transfer area, etc.
