The standard operation of a screw compressor unit is an important step to ensure the unit works well and has a long service life. Below lists are the steps: 1. Refrigerant gas charged. The  screw compressor unit  needs to charge refrigerant on site. The refrigerant quantities and type must be in accordance with the regulations. Before charging, the quantities of refrigerant should be enough. In these cases, when the refrigerant charge is insufficient, it will lead to insufficient cooling capacity. When the refrigerant charge is too large, it will not only increase the cost but also have a negative impact on the operating energy consumption. 2. Operation of the screw compressor unit After the finished refrigerant is charged, we need to power on to operate and set the unit. During operation, bellows need to notice. (1) Check if all valve on the compressor unit is opened completely. Especially the discharged valve. (2) For water-cooled or water chiller unit, please open the conde...

oil return efficiency   Compressor oil is very important for the crankshaft in refrigeration equipment. Under the serious disability of oil, the compressor could wear down within a few hours. 1.  Compressor oil is very important for the crankshaft.  Under the serious disability of oil, the compressor could wear down within a few hours. 2. So during the installation of a split system, we should  pay attention to the copper pipe. If the compressor is higher than the evaporator, the copper loop is a must. The suction line should be as short as possible, as little welding as possible, etc. 3. After all copper welding is done and during the machine commissioning, we should  calculate oil return speed. How many time does it start to return after the compressor start? We must guarantee oil return is on time, so the whole system could run in good condition during its service life.   For more, please feel free to contact us!
