Refrigeration compressors are one of the most important components of the refrigeration system when comparing the refrigeration system to the human body system, and are the core and heart of the vapour refrigeration system. It inhales low-temperature and low-pressure refrigerant gases from the inhaler pipe and compresses them with a piston driven by an electrical operation, thus achieving a cooling cycle. This is followed by a brief introduction to the attention given to refrigeration compressors and to the maintenance of refrigeration compressors。
I. What is a chiller compressor
The ability and characteristics of compressors determine the capacity and characteristics of refrigeration systems. In a sense, refrigeration systems are designed to match the ability of compressors. As a result, a great deal of effort has been devoted to research on refrigeration compressors in all parts of the world, and new research directions and findings are emerging. Compressor technology and performance levels are constantly changing. Compressors are of a wide variety and, depending on the rationale, chillers can be divided into fixed and variable charge compressors。
Ii. Attention to refrigeration compressor maintenance
1. Regular inspection of the presence of miscellaneous and even conductive objects in the electric power plant, damage to the wire, friction of the fixed, rotor, otherwise the electrical motor will burn down
2. To observe the hygiene of the compressors and the equipment and environment of the heating and wet test boxes ... Periodically clean up the ash on the compressor condensers ... Because too much dust accumulates to cause overpressure or non-refrigeration of the equipment
3. To observe whether the lubricant in the oil tank and in the oil-plugs should be filled in a timely manner if it is lower than the tic line (a stop-check of the meter)
Carefully examine the sound of the action of cylinders and motor units at all levels of the hot and wet test tank, identifying its performance on the basis of “hearing”, and immediately suspending if an abnormal sound is detected
5. The lubricant used is subject to sediment filtering. The winter and summer compressor oils are used differently。
6. In the event that water cannot reach the water immediately after a cold compressor has broken off, it is necessary to avoid gas tank cracks due to the cold and heat imbalance ... The cooling water is to be released after the winter stop in order to avoid the fissure of the cylinders, etc.; wind-cooling is as long as the indoor temperature is not too cold and hot, the plant suggests that it would be preferable to leave it in a standard laboratory with air conditioning, with constant temperature at 25-28 degrees。
7. To detect, by hand, whether the temperature is normal at, for example, the venting cap at the cross-track of the high-temperature condensation test box
8. Check the cooling temperature and flow of water in the heating and wet test tanks
9. Checks whether the compressor is vibrating, or whether the snails of the ground are loose and falling
10. Note whether the specified values for pressure tables and lubricating oil pressure tables in the thermostats, gas tanks and coolers are within specified limits
11. Examination of the supply of lubricating oil in hot and wet test boxes, and the provision of oil in the lubricating system of the motor agencies (some compressors have organic glass slabs on the side of the cross-cruiser that can directly see the availability of cross-cruising and lubricating oils); gas cylinders, fillings, which can be used for single-direction testing to check the discharge of oil in the gas tank
12. To note whether the temperature of the electric power, bearing temperature and voltage gauges, current gauges are normal, the current must not exceed the rated electrical current, and if that is exceeded, the cause or the stoppage check
13. Is there any noise during the electric heating process
14. Check the sensitivity of pressure or load adjusters, etc., to safe logging, for example, in the heating and wet tank
Regular clean-up of refrigeration systems, especially copper tubes and bottles. Regularly view freon surplus
16. Gas tanks, coolers and oil-water separators are regularly released。
Synopsis: this is an introduction to the attention given to chiller compressor maintenance, and it is hoped that it will help you. For further information, please continue to focus on the web information platform. The follow-up will be more interesting。
