The air-cooled chiller is a temperature
control device that is widely used in the microchannel reactor industry. Wuxi
Guanya LNEYA has produced a cold and heat source thermostatically controlled
air-cooled chiller for the microchannel reactor industry. If the compressor
fails during operation, it needs to be investigated and solved in time.
To troubleshoot the micro-channel reactor thermostatically controlled air-cooled chiller compressor, first check the circuit part to see if the equipment power supply, voltage, and switch are normal; see if the equipment power supply is powered, the voltage is normal, and the switch contacts are good , Whether the power supply lacks phase. When the equipment is not equipped with an ammeter or a voltmeter, a multimeter or a tester can be used to check the power supply. When the power supply voltage is too low, the compressor cannot be started.
If the compressor of the micro-channel reactor thermostatically controlled air-cooled chiller adopts a piston compressor, whether the big end bearing bush and the curved sleeve of the connecting rod are caught. These may be caused by the excessively high exhaust temperature during the previous operation, or it may be caused by the coking of the lubricating oil, which causes the cylinder and the piston to stick together, which prevents the compressor from starting.
Check the thermostatically controlled air-cooled water chiller differential pressure relay and high and low voltage relay of the microchannel reactor. When the oil pressure of the compressor is abnormal, the compressor can be stopped. At the same time, when the compressor discharge pressure and suction pressure are abnormal, neither of them can be started or the compressor will quickly stop running after it has been started. Check whether the amount of chilled water, cooling water, and water temperature are normal. If the water volume is small and the water temperature is high, it will cause the condensing pressure to rise sharply and the evaporation temperature to drop rapidly. Due to the action of the unit protection facilities, the unit often shuts down quickly.
Check whether the solenoid valves and regulating valves related to the equipment are malfunctioning, and whether they are opened or closed as required. Check whether there is a leakage of working fluid in the temperature sensing bag of the temperature relay, or the adjustment is wrong.
Before use, the corresponding preparations must be done well in order to run efficiently.
