Refrigeration Compressor Compressor Principle Refrigerator Compressor House Decoration Precautions Home Decoration Precautions The globe valve is used to cut off the flow of the medium. The globe valve is suitable for frequently opened occasions. The sealing parts of the globe valve are the disc and the valve seat. In order to make the globe valve close tightly, the mating surface of the disc and the valve seat should be grinding or using gaskets. The sealing surface can also be inset with bronze, stainless steel and other corrosion-resistant and wear-resistant materials. The disc and stem of the globe valve are connected with each other, so that the disc and stem are closely fitted. The lifting of the disc of the globe valve is generally controlled by the stem. The upper part of the stem of the globe valve is the handwheel, and the middle part is the thread and packing sealing section. The role of the packing is to prevent the internal medium of the valve body from leaking along the stem.

First, what is the ability and characteristics of refrigeration compressor compressors determines the capacity and characteristics of the refrigeration system. In a sense, the design and matching of the refrigeration system is to reflect the capabilities of the compressor. Therefore, the refrigeration industry in the world has invested a lot of energy in the research of refrigeration compressors, and new research directions and research results are emerging. The technical and performance levels of compressors are changing with each passing day. There are many kinds of compressors. According to different working principles, refrigeration compressors can be divided into fixed displacement compressors and variable displacement compressors.
Second, the refrigeration compressor maintenance matters needing attention 1. Always check the motor for debris and even conductive objects, whether the coil is damaged, the stator, the rotor friction, otherwise the motor will start to burn out;
2. Pay attention to the hygienic of the constant temperature and humidity test chamber compressor and its equipment and environment. Periodically clean the ash on the condenser of the compressor. Because too much dust accumulates, it will lead to overpressure or non-refrigeration of the equipment.
3. Observe whether the oil level in the oil sump of the fuselage and the oil in the oil injector are lower than the tick marks. If it is low, add in enough time (check with the dipstick to stop);
4. Carefully check the operating sound of the air cylinders and moving parts at each level of the constant temperature and humidity test box to determine whether it is working properly according to “listeningâ€, and stop the inspection if abnormal sound is found;
5. The lubrication machine used for precipitation filtration. Compressor oil in winter and summer should be used differently.
6. If the water-cooled compressor can not immediately enter the water if water is cut off, avoid cracks in the cylinder due to uneven cooling and heating. After parking in winter, the cooling water should be drained to avoid freezing at the cylinder, etc. Suddenly hot and cold can be, manufacturers suggest that it is best to put in the standard laboratory, equipped with air conditioning, the temperature can be constant at 25-28 degrees constant is appropriate.
7. Feel the temperature under normal conditions such as the suction and exhaust cutting cover at the cross guide of the high and low temperature alternating humidity guide test chamber.
8. Check whether the temperature and flow of the cooling water in the constant temperature and humidity test chamber are normal.
9. Check whether the compressor is vibrating and whether the anchor bolts are loose or fall off.
10. Pay attention to whether the indicated values ​​of the pressure gauges, oil pressure gauges and lubricating oil pressure gauges at all levels of the constant temperature and humidity test chamber, the gas reservoir and the cooler are within the specified range;
11. Check the supply of lubricating oil in the constant temperature and humidity test chamber and the lubrication system of the moving mechanism. (Some compressors have plexiglass baffles on the side of the crosshead guide of the fuselage, and you can see the crosshead motion and the lubricating oil directly. Supply conditions); cylinders, packing can be used for one-way cutting oil inspection, you can check the oil injector to the cylinder of oil;
12. Pay attention to the temperature rise of the motor, the bearing temperature and voltmeter, and the indication of the current meter is normal. The current must not exceed the rated current of the motor. If it exceeds, check the cause or stop the machine.
13. Is there abnormal sound in the process of temperature rise of the motor;
14. Check whether the pressure regulator or load regulator of the constant temperature and humidity chamber is safe and sensitive.
15. Clean the refrigeration system regularly, especially the copper tube and bottle body. Check Freon's balance regularly;
16. Gas tanks, coolers, oil-water separators should always release oil and water.
Xiao Bian concludes: The above introduced the precautions for refrigeration compressor maintenance and hoped to help everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.
If the refrigeration system is compared to the human body system, the refrigeration compressor is one of the most important components in the refrigeration system and is the heart and heart of the vapor-type refrigeration system. It sucks cryogenic low-pressure refrigerant gas from the suction pipe, and drives the piston through the motor to compress it, so as to realize a refrigeration cycle. Next Xiaobian to introduce what are precautions refrigeration compressors and refrigeration compressor maintenance.
