How to maintain the key components of industrial chiller machine?

(1) Replace lubricating oil

After the GX/GY -65°C ~ -10°C Industrial Refrigerators has been used for a long time, the oil quality of the lubricating oil will deteriorate, and the impurities and moisture in the oil will increase. Therefore, the oil quality should be regularly observed and checked. Once problems are found

Replace in time, and the brand of the replaced lubricating oil must conform to the technical data.

(2) Maintenance of drying filter

Since water and refrigerant are not miscible with each other, if there is water in the system, it will greatly affect the operation efficiency of the unit. Therefore, it is very important to keep the system dry

It is necessary to dry the filter for normal use. Generally, the filter element of the dry filter needs to be replaced regularly.

(3) Regularly calibrate the safety valve

The condenser and evaporator of the refrigeration equipment are pressure vessels. It is required to install a safety valve to prevent the possible harm to human body caused by high pressure. For the sake of safety

The valve needs to be regularly verified for normal pressure relief.

(4) Clean the condenser and evaporator

Generally, since the cooling water is an open circulating circuit, tap water is used for recycling through the cooling tower, so when the quality of the cooling water used is poor

Clean the pipe at least once a year to remove the scale and other dirt in the pipe. The pipe can be cleaned with a special pigging gun or the cleaning agent can be circulated.

1. The solution for non-cooling of water chiller.

The filter screen is blocked. When the filter screen is blocked, the dust on the condenser will accumulate more and more, which will affect the cooling effect of the refrigeration equipment over time. In the long run, it may even lead to the failure of refrigeration equipment. The solution to the clogging of the filter screen of the water cooler: clean the filter screen regularly or irregularly.

The content of coolant is too low, which will cause the equipment to absorb oil and reduce the cooling effect. Solution to low coolant content: check the coolant frequently to see if the coolant level is maintained between high and low, and add coolant in time when the coolant is too low.

Lack of freon. In some early refrigeration equipment using freon as refrigerant, freon will volatilize after a long time of use, thus affecting the refrigeration effect. Freon is added.

The power supply voltage is low or the power of refrigeration equipment is insufficient.

2. What are the components of the refrigeration system?

The refrigeration system is composed of compressor, condenser, throttling component and evaporator.
