What kind of preheating work can avoid the failure of screw chiller

The following is a small knowledge point to ensure the normal, safe and stable operation of the screw chiller. If you want to be a qualified chiller operator, you must continue to learn and absorb a more comprehensive working principle of the chiller and its components, and the chiller Information about operation procedures, daily maintenance of chillers, and other related information can reduce operating costs for companies and improve production efficiency. In order to avoid failure of the screw chiller when starting up, what kind of preheating work should be done before starting up?

　　 1. One of the necessary conditions for starting the screw chiller is voltage.

Therefore, first check whether the voltage is the voltage requirement marked on the nameplate, and check whether the circuit is intact. If the screw chiller is turned on and running, there is a voltage instability or a short circuit caused by a circuit problem, which will directly affect the unit's operation. Safe operation may even burn the screw chiller. Therefore, before starting, it is necessary to ensure that the voltage and current of the screw chiller meet the operating requirements of the unit, so as to reduce the failure rate of the screw chiller and increase the operating power.

　　2. After confirming that the voltage and current meet the startup requirements of the screw chiller, determine whether the water system is normal.

　　 After all, the main function of the screw chiller is to provide low-temperature chilled water to the enterprise. Therefore, not only must the water source be sufficient, but also the water pipes must be trouble-free. For poor water quality or low water flow, companies should do a good job of testing in advance. The integrity of the water system can ensure the safe operation of the screw chiller and avoid various failures.

　　3. The important condition for the screw chiller to produce low-temperature chilled water is inseparable from the credit of the refrigerant.

　　 Observe whether the amount of refrigerant is within the standard range, and judge directly by the high pressure and low pressure values ​​of the high and low pressure gauges on the screw chiller. If the value of the pressure gauge is reset to zero, or the high pressure is too high and the low pressure is too low, it must be checked and eliminated in time before the screw chiller can be started normally to ensure the stable operation of the screw chiller.
