What is the reason why the compressor of the air-cooled chiller cannot be started in the East Leap Refrigeration Analysis?

Air-cooled chiller | Air-cooled chiller refrigeration compressor | Air-cooled chiller failure - The compressor of the air-cooled chiller cannot start because: The compressor is the core component of the air-cooled chiller, if not start, then the whole Taiwan units will not be able to work. Therefore, when the compressor is started, it is necessary to know in detail the data range of various instruments and meters (such as thermometers, pressure gauges, flow meters, voltmeters, ammeters, etc.) during the normal operation of the air-cooled chiller cooling system, so that the data can be based on relevant data. Excluding various abnormal phenomena.

In case the refrigeration compressor of the air-cooled chiller you purchased cannot be started, or it is stopped soon after startup, we should check from the following 6 aspects:
1, first check the main circuit. If the power supply has power, the voltage is normal, whether the fuse has been blown due to the start overload, the air switch is tripped, the switch contacts are good, and the power supply is missing phase. Observe the voltmeter and ammeter when starting, and when the chiller is not equipped with an ammeter or voltmeter, use a multimeter or a stylus to check the power supply. When the power supply voltage is too low, the compressor will not start.
2. For the piston refrigeration compressor, whether the shaft of the connecting rod big head bush and the curved sleeve will hold the shaft. These may be caused by the exhaust gas temperature being too high in the past operation, or it may be the coking of the lubricating oil, which causes the adhesion of the cylinder and the piston to cause the compressor to fail to start.
3, check the differential pressure relay and high and low voltage relays. When the compressor's oil pressure is abnormal (above or below a certain value), the compressor can be stopped. At the same time, when the compressor discharge pressure (high pressure) and suction pressure (low pressure) are abnormal, the compressor will not start immediately or after it has been started.
4, check the amount of frozen water, cooling water, water temperature is normal. If the water volume is small and the water temperature is high, the condensing pressure will rise sharply, and the evaporating temperature will drop rapidly. Because the unit protection facilities act, they often stop quickly.
5, check whether the relevant solenoid valve, regulating valve failure, whether to open or close as required.
6. Check whether there is leakage of working medium in the temperature sensing package of the temperature relay or if the adjustment is incorrect.

These reasons often cause the chiller's refrigeration compressor to fail to start, or start for a few minutes, or stop for more than ten minutes. At this time, we must carefully look for the reasons. We must not force the start before we can identify the reasons, so as not to damage the air-cooled chiller.
