Operation steps of chemical low temperature heating unit

The chemical low temperature heating unit is a kind of equipment that can provide constant cold source and heat source to the reactor.
It uses the principle of mechanical refrigeration to achieve rapid cooling, and can quickly heat and refrigerate.
It is equipped with laboratory equipment such as reactors and evaporators
.

1.
It should be operated and managed by special personnel, and the abnormality should be stopped in time to find out the cause and eliminate the fault.
It is strictly forbidden to run the unit with a fault and it has reached the working state after adjustment
.

2.
Special attention is that users should not arbitrarily change the set operating parameters.
Changes may cause unnecessary effects on the product, not to mention the effect, if other failures occur
.

3.
The main circuit power switch of the equipment cannot be disconnected during normal use to maintain the normal operation of the compressor oil heater
.

Frequent operation of each switch is strictly prohibited
.

　　4.
The condenser and evaporator should be cleaned at least once every two years
.

This extends the life of the product and stabilizes the effect
.

　　5.
Check whether the fastening bolts of the power connection are loose
.

Whether the high and low pressure values ​​of the refrigeration/heating system are normal, whether the running current of the compressor and the insulation resistance of the unit are normal
.

　　6.
Whether the drying filter and the sight glass are normal, if the outlet of the filter is frosted, it indicates that the filter is dirty and blocked, and the filter screen needs to be cleaned
.

　　7.
Whether the compressor lubricating oil is normal, if the oil level is lower than 2/3 of the sight glass during operation, add lubricating oil.
If there is dirt or deterioration, replace the lubricating oil, and clean or replace the oil filter.
Also replace the filter drier cartridge
.

The chemical low-temperature heating unit has many characteristics.
It adopts fully automatic mode, automatic heating and cooling, which can reduce energy consumption.
It is a widely used equipment at present.

.

When using it, pay attention to the requirements and strictly follow the operation steps, otherwise problems will easily occur
.

In addition, maintenance work is also very important
.
