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...

O que é a falta de óleo no frigorífico de temperatura ultra baixa de 120 graus?
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 ...

Como resolver o problema do congelamento do dispositivo de circulação a baixa temperatura?
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 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...

Instruções de esvaziamento e enchimento do aparelho de teste linear de mudança rápida de temperatura
Before starting the linear rapid temperature change tester, check whether the relevant protective measures are in place, such as fire protection, protection, leak prevention and other tools. Check whether the power supply is in place according to the power supply installation and equipment grounding, whether the phase sequence is correct, and whether the grounding is good. Then power on the equipment, and then check whether the relevant valve is open. Otherwise, the circulating pump will be b...

Battery test water cooler common knowledge description
Battery test Water-cooled air intake If there is no superheat, there may be a return air with liquid, and even cause a wet stroke liquid shock to damage the compressor. In order to avoid this phenomenon, a certain degree of suction superheat is required to ensure that only dry steam enters the compressor (the presence of superheat indicates the complete evaporation of the liquid refrigerant due to the nature of the refrigerant). However, the battery test water cooler has too high superheat an...

Como escolher o sistema de controlo da temperatura de arrefecimento e aquecimento?
The price of the refrigeration heating temperature control system is not the main factor. The main purpose is to implement the temperature control technology through the temperature control function. However, it is not the temperature control system of each refrigeration heating temperature control system manufacturer. All are the same, the industry has specialization, the technology of different manufacturers is also different, so users need to choose well, whether the refrigeration heating ...
