How to size a chiller for spot welding machine?
Dec 17 , 2021
Spot welding machine is a kind of mechanical equipment. It adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current changes from one When the electrode flows through the other electrode, the two conta...

What causes the high-pressure failure of your water chiller machine? How to solve it?
Dec 22 , 2021
The high-pressure failure of the chiller means that the compressor discharge pressure is too high, which causes the high-pressure protection relay to operate. The compressor discharge pressure reflects the condensing pressure, the normal value should be 1.4~1.8MPa, and the protection value setting is recommended not to exceed 2.0MPa. Because the long-term pressure is too high, it will cause the co...

What are the differences between air-cooled chillers and water-cooled chillers
Jan 06 , 2022
We all know that according to different heat dissipation methods, chillers can be divided into air-cooled chillers and water-cooled chillers. What is the difference between air-cooled chillers and water-cooled chillers? 1. The air-cooled chiller uses copper tubes and aluminum fins to dissipate heat from the condenser. A fan is required to blow the outdoor air through the heat exchange fins and tak...

Reasons and solutions for the internal protection of screw compressors | Oumalchiller.com
Feb 15 , 2022
The compressor is the heart of the chiller, and the normal operation of the compressor is the basis for the normal operation of the chiller. Therefore, if we want to understand the chiller, we must first understand the compressor. Today we will talk about the reasons for the internal protection of the semi-hermetic screw compressor. There is a thermal switch inside the screw compressor. The functi...
