The user must know that the performance of the heating and cooling cycle system in the Water Chiller Machine For Factory is very important. Then, if the heating and cooling cycle system fails, it will cause the entire heating and cooling cycle system to fail to operate effectively. Therefore, if there is a failure, it needs to be timely Effective solution. How does the Air-Cooled Do chiller Exporter face the failure of the heating refrigeration cycle system?
The heating and refrigeration cycle system unit cannot be started. It is necessary to check whether the heating and refrigeration cycle system unit has high pressure, whether there is a power failure, whether there is oil accumulation of excessive liquid in the body, whether the pressure relay alarm is not reset, and whether the unit is in the alarm state and not reset. Common faults include high oil temperature alarm, high exhaust pressure, motor overload alarm, etc. By checking the control cabinet (manual unit) or console control screen (automatic unit), check the cause of the alarm, eliminate and reset.
Module Air-Cooled HeatPump
Of course, you also need to check whether the heating and refrigeration cycle system has low oil pressure, whether the zero load switch is damaged or the zero load cam is loose. Even when the compressor is in the zero load position, there is no zero load signal input. After starting, the compressor is always in the unloaded state, which will cause the spool valve not to alarm and the compressor cannot start. Check whether the zero load switch of the compressor is flexible and normal. If it is abnormal, it needs to be replaced. Check whether the cam is loose so that the zero load switch cannot be closed. If the cam is misaligned, adjust its position and tighten.
At the same time, it is also necessary to pay attention to the burning or short circuit of the motor winding of the heating and refrigeration cycle system. Check motor, compressor and motor coaxiality is out of tolerance, recalibrate coaxiality.
Check the contactor, intermediate relay and other electrical components in the control cabinet for failure, check the circuit wiring between the control cabinet and the console for errors, check the circuit and check the compressor for wear and burn. After the heating and refrigeration cycle system fails, the related failures of the heating and refrigeration cycle system are resolved in a timely and effective manner according to the solution, so that the heating and refrigeration cycle system operates more efficiently.
