Screw chiller, refrigeration unit, industrial chiller

With the improvement of production process requirements, screw chillers, refrigeration units, and industrial chillers are becoming increasingly widely used in enterprises. It is important to pay attention to the correct commissioning of screw chillers, which is an important link in the normal operation, energy saving, and extended use of refrigeration units

Screw chiller, refrigeration unit, industrial chillerFunction introduction:

The main unit of the screw chiller adopts the advanced third-generation 5:6 asymmetric rotor semi enclosed screw compressor, motor and compressor, integrated, without shaft seal leakage concerns. The combination control program of two or more compressors reasonably balances the load of the head components and extends the unit The compressor adopts star delta voltage reduction starting to avoid impact on the power grid The total number of parts in a screw compressor is only one tenth of that of a reciprocating compressor, with a simple structure, few vulnerable parts, low resistance to wet running, and extremely low failure rate Equipped with an internal oil separator and a three-stage oil filtration mechanism, the best oil and gas separation is achieved. With a wrapped design, the compressor's operating noise can be reduced to the lowest level possible, and the screw compressor can operate with a fault free rate of over 40000 hours

Protective measures during startup:

If a power outage causes the main engine to shut down, due to the failure of the bypass solenoid valve to open, the compressor may reverse under the pressure difference between exhaust and suction. At this time, the suction cut-off valve should be quickly closed If the temperature is low during the season, the electric heater on the oil separator should be turned on first and the oil pump should be started to circulate the oil before starting the machine If the machine automatically shuts down due to a certain protective action, the faulty component must be identified before starting the machine. It is not allowed to start the machine arbitrarily by changing the set value
