Plate heat exchange unit: How to judge whether the plate heat exchange unit is blocked?
Release time:

If the pressure difference between the supply and return water at the primary side or the pressure difference between the inlet and outlet of the secondary side heat exchanger exceeds 0.15 MPa, and the temperature of the secondary water supply is not hot, please check whether the plate heat exchanger unit is blocked.
How to judge whether the plate heat exchange unit is blocked? The plate heat exchange unit is composed of heat exchanger, circulating pump, make-up water pump, electrical control cabinet, filter, base, pipeline, valve, instrument, etc., and can be installed with automatic constant pressure make-up water device, water treatment equipment, water tank, water pump frequency control, temperature control valve, remote communication control, etc., thus forming a complete heat exchange station.
How to judge whether the plate heat exchange unit is blocked?
If the pressure difference between the supply and return water at the primary side or the pressure difference between the inlet and outlet of the secondary side heat exchanger exceeds 0.15 MPa, and the temperature of the secondary water supply is not hot, please check whether the plate heat exchanger unit is blocked.
What is the reason why the system is not hot?
The water supply flow on one side is insufficient, and the system on the two sides is not smooth.
The system has pressure, and the pressure gauge shows 0. What's the matter?
If the needle valve of the pressure gauge is closed, the pressure gauge will always display 0. During the system operation, ensure that the needle valves of all pressure gauges are fully open.
What is the secondary side overpressure?
During the initial operation of the plate heat exchange unit, the secondary temperature is relatively low. After the water supply reaches the fixed pressure value, the pressure of the secondary system will also increase with the increasing temperature. At this time, one is more exhaust and the other is drainage.
How to judge whether the filter of plate heat exchange unit is blocked?
If the temperature difference between the water supply temperature and the return water temperature is large, the high temperature water exceeds 45 degrees, and the low temperature water exceeds 30 degrees, please check whether the filter at the water supply is blocked.
The make-up pump has been running, but the pressure has not increased?
If the make-up pump has been running, but the pressure has not reached the set value, please exhaust the system. Poor water supply is mostly caused by gas gathering in the system.
What is the reason why the frequency converter does not start when the frequency converter does not make up water automatically?
Check whether the transfer switch is in the frequency conversion or automatic position. The frequency converter must be in the frequency conversion or automatic position to work normally.
The above is how to judge whether the plate heat exchanger unit is blocked. I hope it can help you!
