Description of the compressor of the high and low temperature damp heat test device

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 to energy conservation and emission reduction, we must also make our own efforts. Doing this, and the loss of machinery is not much of a benefit to us, and the other is to choose less noise, so as not to affect our rest. High and low temperature dam...

Motor cooling system tests the effect of condensing temperature

The 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 heat pipe is greatly reduced compared with the first half. It is because the refrigerant in the second half of the tube has gradually liquefied, and the condensation temperature and the supercooling temperature have been reached. When the motor cooling ...

Reasons for the decrease of heat transfer effect of vertical ultra-low temperature refrigerator

If 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 of the evaporator. Because the vertical ultra-low temperature refrigerator has relatively high humidity, the moisture in the air is easy to frost on the surface of the evaporator, and even freezes, which affects the heat transfer effect of the evapo...

Semiconductor refrigeration temperature control table cooler operation instructions

The 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 between the active and standby working power sources. When the common power failure occurs, it automatically switches to the standby power supply. When both power supplies are normal, the common power supply works and the standby power supply is in stan...

What is the lack of oil in the 120-degree ultra-low temperature refrigerator?

The 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, etc., it is the basic requirement for maintaining the normal operation of the -120 degree ultra-low temperature refrigerator. Therefore, Wuxi Yuze suggested that the 120-degree ultra-low temperature refrigerator manufacturer requires the use of designa...

Multi-stage refrigeration small temperature control compressor description

The 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 condenser, the high pressure superheated refrigerant vapor condenses at the condenser temperature. Then, through the throttling element, the liquid mixture after the natural gas is reduced flows into the evaporator, and the refrigerant liquid absorbs ...

How to solve the frosting of the low temperature circulation device?

The 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 circulation device, but the low temperature circulation device evaporator cannot normally absorb the heat supply refrigerant expansion; It may also be because the evaporator is in a normal working state but the refrigerant supply throttle valve is too large, ...

Motor test chiller compressor causes wear

Motor test chiller compressor causes wear

Motor 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 crankshaft wear. High-speed multi-cylinder compressors have high requirements for the quality and lubrication performance of the motor test chiller oil due to high speed, high load and high exhaust gas temperature. Motor test chiller refrigeration compressor...

How to choose the lubricant for the injection molding machine?

The 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 in direct contact with the compressed refrigerant, and the lubricating oil should be considered. The problem of interaction between the refrigerant and the refrigerant. The lubricating oil used in the centrifugal injection molding machine cooling sys...
