How to maintain the fully enclosed refrigeration and heating cycle device

During the operation of the fully enclosed refrigeration and heating cycle device, care should be taken to avoid some factors that cause no cooling or no heating
.

For example, the equipment environment is not ventilated, there are many ash layers on the surface of the equipment, the refrigerant is missing, the refrigerant is insufficient, and the filter is blocked.
Pay attention to these details during operation, and do a good job in maintenance to make the equipment operate effectively for a long time
.

The fully enclosed refrigeration and heating cycle device can be connected to the liquid inlet and liquid outlet of the reactor, and the heat transfer medium enters from the liquid inlet
.

After startup, the air in the system can be exhausted, and after the desired temperature is set, the system can operate automatically
.

In the process of process control, according to the temperature, explosion-proof and size of the materials in the reactor, the control system is designed according to the different characteristics and requirements of the customer's site, so as to meet the temperature required for the cooling and heating control of the heat transfer medium or the reaction material
.

There are temperature restrictions on the use of the refrigeration compressor of the fully enclosed refrigeration and heating cycle device
.

Exceeding or falling below this temperature will affect the use effect and service life
.

Then, if the compressor suction temperature is too high or the condensing temperature is too high, attention should be paid to it
.

And can not run under the condition of insufficient refrigerant, otherwise it will affect the heat dissipation of the motor winding and accelerate the aging of the insulating material
.

The power supply of the equipment is generally three-phase four-wire
.

If there are unconventional items that need to be distinguished, prepare power supply, zero connection, grounding and other circuits in advance to ensure tight connections
.

The surface temperature of the casing of the fully enclosed refrigeration and heating cycle device exceeds the normal range, mainly because the suction temperature of the refrigeration system is too high, and the excessively high hot steam enters the compressor.
The temperature of the casing is increased, and even the lubrication of the moving parts will be affected, and the wear will be accelerated.
In severe cases, the bearing will hold the shaft
.

In addition, it will cause the exhaust gas temperature to rise
.

　　The method to determine whether the temperature of the fully enclosed refrigeration and heating cycle device is abnormal is to touch it by hand.
If it is found that the temperature is abnormal during use, it needs to be dealt with in time
.
