Trouble shooting method for water cut off of cooling system driven by wheel motor
Long-term use of the wheel motor to drive the cooling system can encounter any kind of failure. For the wheel-side motor drive cooling system, if there is a water cut problem, it is very dangerous and must be dealt with in a timely and effective manner. If the processing time is delayed, it will cause serious failure of the wheel motor drive cooling system, and even cause the equipment to fail to operate normally. When the wheel motor drive cooling system is used daily, the heat dissipation ...

What are the precautions when choosing an industrial chiller?
An industrial chiller is a refrigeration device that assembles a refrigerator, condenser, evaporator, expansion valve, control system, and switch box on a common base or frame. According to the heat removal method of the unit, it can be divided into water-cooled and air-cooled chillers. The latter adopts heat pump circulation and is welcomed by users. After fully considering the above factors, when choosing a chiller, you should also pay attention to the following point: 1. Generally, 2 to 4 ...
