Different types of compressors for high and low temperature damp heat test devices often have an impact on price. When choosing, we should choose low-energy refrigeration compressors as much as possible. Now China is paying more and more attention...
View detailsThe motor cooling system tests the condenser. Under normal conditions, the first half of the heat pipe is very hot, and its temperature has a slow and slow gradual decline in the balance of power. The heat sensitivity of the second half of the hea...
View detailsIf the outer frost layer of the vertical ultra-low temperature refrigerator is too thick or excessively dusty, it can be caused because the external temperature of the evaporator is mostly lower than 0 °C, resulting in low heat transfer efficiency...
View detailsThe power supply switching of the control system of the transformer cooling system of the semiconductor refrigeration temperature control station uses the imported dual power automatic switching device. Its main function is automatic switching bet...
View detailsThe compressor of the -120 degree ultra-low temperature refrigerator is a complex component that runs at high speed. In order to ensure sufficient lubrication of the moving parts of the compressor crankshaft, bearings, connecting rods, pistons, et...
View detailsThe function of the compressor in the multi-stage refrigeration small temperature control station system is to draw the refrigerant vapor of the evaporator and increase its temperature and pressure, which is discharged into the condenser. In the c...
View detailsThe failure of the low temperature circulation device frosting is mainly because the compressor return air temperature is too low, which may be that the throttle valve liquid refrigerant supply is in a normal state in the low temperature circulati...
View detailsMotor testing chiller oil quality may be one of the main reasons affecting crankshaft wear. If the engine oil is used in the chiller refrigeration system, the engine oil that does not meet the requirements and is of poor quality may cause cranksha...
View detailsThe injection molding machine cooling system lubricating oil needs to pay attention to the type of compressor when selecting. The compressor has three types: piston type, screw type and centrifugal type. The first two kinds of lubricating oil are ...
