It is a kind of heat exchange equipment for cooling fluid. Usually, water  air is used as a coolant to remove heat. It can be divided into tube cooler, plate cooler  air-cooled cooler. Cooler is a kind of heat exchange equipment, usually used in metallurgy, chemical industry, energy, transportation, light industry, food  other industrial fields. It is suitable for different working conditions, such as cooler, condenser, heating, evaporation, waste heat recovery, etc. Therefore, in many types of heat exchanger, cooler  tube heat exchanger still occupy an important position. The installation method of cooler is divided into vertical oil cooler  horizontal oil cooler. The vertical cooler has small installation area  convenient installation. Horizontal oil cooler has the characteristics of small pressure drop  strong water impact resistance. Therefore, vertical  horizontal oil coolers can be selected correctly according to the requirements of different places, space height  performance. Other equipment requirements. 

(1) the water chiller must pass the pressure test before use  drain the internal water before use. 

(2) check whether the pouring  exhaust valves are flexible, easy to use  switch positions,  whether the pressure gauge  thermometer have been installed. 

(3) check whether the foundation  support are firm  whether the bolts are fully tightened. 

(4) when put into use, the cold flow shall be discharged first,  then the heat flow. 

(5) when using cold  hot media, first make sure that the auxiliary pipeline is unobstructed,  then slowly open the outlet valve. After checking that there is no problem, open the intake valve. It must be opened slowly to prevent pressure. During commissioning, please pay attention to the change of the equipment. After the cooler is put into use, the change of temperature  pressure may cause leakage, so it should be checked in time.
