Refrigeration control system compressor failure caused by oil pressure
If there is no oil pressure in the refrigeration control system, check the oil pump piping system connection for oil leakage or blockage. If the connection is loose, the joint should be tightened. If it is blocked, the oil pipeline should be cleared. Then check whether the compressor of the refrigeration control system is too large due to the opening of the oil pressure regulating valve or the valve core is detached. If the hydraulic pressure regulating valve of the refrigeration control syst...

Discrimination of power battery integration test system
Using the degree of superheat to judge whether the opening degree of the integrated test system of the power battery is appropriate, and using a thermometer to measure the difference between the temperature of the return pipe and the evaporating temperature (ie, the actual superheat) and the standard superheat (between 5-8 ° C) Check to see if the adjustment is appropriate. Using the suction pressure of the compressor as the saturation pressure in the evaporator, the table looks for an approx...

The reason why the cooling water circulator needs the main water circulation
The supplement of the water cycle is directed to a water-cooled cooling water circulator, and the air-cooled cooling water circulator does not have this problem. The water-cooled cooling water circulator needs cooling water during normal operation. The cooling circulating water is the most important part of the whole water-cooled cooling water circulator. However, the water-cooling system of the water-cooled cooling water circulator is in the process of normal operation. What is the main reas...

View detailsEnergy Conservation is Crucial for Developing Ultra Low Temperature Recirculating Chillers
With the continuous development of chemical, refrigeration and pharmaceutical industries, environmental pollution is put on the agenda earlier. As an editor of which is the industrial chiller, I can say that except for corresponding to the environmental protection theme, we apply environmental friendly ultra low temperature recirculating chillers for the equipment, increasing the efficiency constantly. So what should be done specifically?Industrial chiller units lower the condensing temperatu...
View detailsExplanation Protection for Air Cooled Precision Chiller
The places where need air-cooled precision chiller indicate they have high demanding for operating accuracy. Therefore, the protection settings have to work out. Then, which kind of protection for air-cooled precision chiller should be done?Discharging temperature protector should be installed on the air-cooled precision chiller in order to protect the compressor when it works with negative high stressing or without enough refrigerants. The temperature detected in the position of 10cm between...
View detailsThe Reasons of Frosting on Ultra low Temperature Recirculating Chillers
Frosting will appear when many users take advantage of ultra low temperature recirculating chillers, while some are not. It is confusing and whether it is relevant to refrigeration.First of all, why does ultra low temperature recirculating chillers frost? To sort it out, we can turn our eyes on the reasons of direct-cooling ultra low temperature recirculating chillers. The frost is a white crystal of vapour which will congeal on the surface of ultra low temperature objects.The air will frost ...
View detailsThe Noise Analysis of Precision Chiller
Generally speaking, even the most sophisticated refrigerating equipment will also have some trouble when used for a long time. If the noises present in the precision chiller after prolonged use, I am sure that it appears some faults. So let's go deeper to see where these noises are from.The noise of compressorThe compressor is in the core position of the inner structure of the precision chiller. In general, compressors include screw and stroll, you can pick up one as what you need. Once the c...
View detailsHow to Debug the Expansion Valve of Low Temperature Freezer?
The effective operation of low temperature freezer is relevant to the needed refrigerating effect. It is crucial to correct expansion valve if better cooling effect is wanted. So, how to debug the expansion valve of low temperature freezer?During the operation of low temperature freezer, the smaller the opening is, the less the volume of fluid transmission and pressure are,and vice versa. Based on the thermodynamic property of refrigerating fluid, the corresponding temperature varies as the p...
