What is the reason for non condensable gas in the condenser of ultra-low temperature cooling water c
When the ultra-low temperature cooling water chiller is running, it is necessary to pay attention to the gas state generated by the condenser under a certain temperature and pressure. The existence of these gases affects the operation of the ultra-low temperature cooling water chiller. What is the reason? 1. The refrigeration system is not fully drained before charging refrigerant Before the ultra-low temperature cooling water chiller is charged with the refrigerator, the compressor cylinder,...

How to replace the four-way valve of the chilled water machine?
The four-way valve of the chilled water machine needs to be replaced in time after a long period of use, so how to replace it? You can look at the suggestions. When replacing the chilled water machine, you need to remove the connecting pipe connecting the compressor exhaust pipe and the suction pipe first. Because the pipes connecting the condenser and the three-way valve on the four-way room of the refrigerator are relatively close, it is not easy to get from the pipe port. Take it out, so ...

How to replace the four-way valve of industrial refrigeration equipment?
The four-way valve of industrial refrigeration equipment needs to be replaced in time after a long period of use, so how to replace it? When replacing industrial refrigeration equipment, you need to first remove the connecting pipe connecting the compressor exhaust pipe and the suction pipe. Because the pipes connecting the condenser and the three-way valve on the chiller four-way are close, it is not easy to take it out of the nozzle. Therefore, the pipe connecting the compressor discharge p...

How to judge the operating status of the chemical and pharmaceutical constant temperature control sy
Nowadays, many pharmaceutical and chemical industries use LNEYA's constant temperature control system. How to judge its operation status during operation? There should be no noise in the cylinder of the chemical and pharmaceutical thermostatic control system, only the normal and regular sound of the inhalation valve. The condenser cooling water should be sufficient, the water pressure should be above 0.12MPA, and the water temperature should not be too high. There should be no foot heating an...

How to use the reactor thermostat?
The reactor thermostat is generally heated by a resistance wire, cooled by a compressor, and is supplemented with a PID controller to maintain a relatively standard temperature, so as to achieve the purpose of the experiment. The shell is made of metal plate, and the control box is directly installed on the water tank. There are two water inlets and outlets for the condensate pipe next to it, and the water pump is used as the circulating power in the water tank, which solves the problem of un...
