Cause analysis of common failures of compressors with heat transfer oil heating system

The energy efficiency ratio of water-cooled chillers is higher than that of air-cooled chillers in terms of supporting heat transfer oil heating system technology. Many people don’t know which is better, water-cooled chillers and air-cooled chillers-in fact everyone has their own age. What I use is good-the air-cooled chiller refrigeration system of the inverter chiller. The condenser plays the role of outputting heat and condensing the refrigerant during the refrigeration process. The high-pressure superheated steam discharged from the refrigeration compressor enters the condenser. All the heat absorbed during the working process, including the heat absorbed from the evaporator, refrigeration compressor and pipeline, is transferred to the surrounding medium water or air to take away the refrigerant. The high-pressure superheated steam is condensed into a liquid. The heat-conducting oil heating system is therefore the chiller.

It is a standard energy-saving equipment. The cooling principle of industrial chillers. The operation of industrial chillers is realized through three interconnected systems. The refrigerant cycle system and the electrical automatic control system. The refrigerant cycle system. The liquid refrigerant in the evaporator. Absorb heat from the water and begin to evaporate. After leak detection, repair it in time.

In fact, how to convert a chiller to a refrigeration unit. Here is an introduction for everyone? Understand the working principle of the refrigerator to better solve operational problems! At the same time, please remember that the water in the water-cooled chiller system must be drained clean and the chiller must be covered with cloth. However, due to the wide application of refrigeration equipment, the requirements of different fields are different, and screw machines are widely used in a large number of cooling needs; Some industrial coolers do not work. Industrial chillers will shut down shortly after startup. High-pressure shut-off action. Pump system failure and low-pressure shut-down action of condensed non-condensable gas. Expansion valve blockage and damage should be cleaned and replaced. User's load is too low to form frequent start and stop industrial cold water The exhaust pressure of the unit is too low, and the refrigerant is insufficient. Check for leaks and replenish the refrigerant. The cooling water temperature is too low. Adjust the flow. Clean and replace the filter element. The exhaust pressure is too high. The refrigerant is pumped out. Air-cooled chillers are different from water-cooled chillers. Water-cooled chillers use water-cooled heat dissipation systems to dissipate heat, while air-cooled chillers use air-cooled heat dissipation systems: it is well known that chillers are equipped with air-cooled heat dissipation systems, which are relatively easy to install, use, maintain, and move.

—Because the cryogenic unit requires a higher compression ratio for the compressor, in most low-temperature fields, the system uses a two-stage compression or cascade compression cycle that is more complicated than single-stage compression...Only in this way can the service life of the refrigerator be prolonged- When using these different types of freezers, it is necessary to carry out regular maintenance and maintenance, especially for some accidents or accidents, which must be properly handled to find out where the problem occurs and take professional maintenance methods. This is conducive to extending its service life-

Analysis of the causes of common failures of compressors with heat transfer oil heating systems. According to different cooling media and cooling methods, the condenser can be divided into three types: water-cooled condenser, air-cooled condenser and evaporative condenser, industrial cooler, liquid reservoir, storage The condenser is installed behind the condenser and directly communicates with the condenser's discharge pipe.

The refrigerant liquid of the condenser should flow into the condenser unimpededly so that the cooling area of

​ ​the condenser can be fully utilized ~ after throttling by a thermal expansion valve or capillary tube It becomes a low-temperature and low-pressure refrigerant that enters the evaporator to complete the refrigerant cycle process.

The refrigeration system basically consists of a compressor. The compressor is a component of the entire refrigeration system and is also the movement of refrigerant compression. If there are replacement valves and pipes, they should be replaced in time. Avoid malfunction of the refrigerator due to leakage. Cold ton means the amount of refrigeration required to freeze a ton of saturated water during freezing hours?

The two types of refrigerators are air-cooled refrigerators and air-cooled refrigerators supporting heat transfer oil heating systems! The chiller is a kind of water-cooled equipment that can provide constant temperature, constant current and constant pressure cooling equipment, and then make appropriate maintenance according to your specific ability to ensure that the industrial chiller re-runs in the shortest possible time. However, we should learn more Air-cooled chillers for better use and maintenance of air-cooled chillers; chillers inject a certain amount of water into the internal water tank of the machine to cool the water through the refrigeration system, and then the circulating water pump inside the machine injects low-temperature chilled water into the equipment to be cooled. The water takes away the heat inside the equipment and then the high-temperature hot water flows into the water tank again for cooling: With the rapid development of various industries, the demand for refrigeration equipment is getting higher and higher-use the refrigerator to clean regularly, so how to clean it If you want to clean the refrigerator thoroughly You should take it out first because some parts are difficult to clean if you don’t take it out... Refilling refrigerant and refrigerating oil after leak detection. Water chiller is one of the important common equipment-condenser condenser is used for output during refrigeration The heat energy and the high-pressure superheated steam discharged from the refrigeration compressor of the condensing refrigerant enters the condenser and all the heat absorbed during the working process, including the heat absorbed from the evaporator and the refrigeration compressor, and the pipeline, is transferred to the surrounding medium water or air. The high-pressure superheated vapor that takes away the refrigerant is condensed into liquid-on the other hand, when the heat load of the evaporator changes, the demand for refrigerant liquid also changes. At that time, the liquid receiver plays the role of regulating and storing the refrigerant.

Analysis of the causes of common failures of compressors with heat-conducting oil heating system. This article mainly discusses the location of the motor and fan of the air cooler.

Is a cooler a machine that achieves a cooling effect through vapor compression or absorption cycle?

The refrigeration range of the chiller is ultra-low temperature refrigeration smaller than deep refrigeration, ordinary refrigeration larger than cold water cooler can be customized into acid and alkali resistant type to meet the special requirements of customers' special processes, or low temperature type to meet the special requirements of customers' special processes for low-temperature coolants! There are still three major shortcomings in China's refrigeration industry. Both types can achieve heat dissipation and cooling effects but their working principles are different.

Although this seems to be a simple step, we still recommend that professionals should clean the refrigerator safely; Please refer to the following methods to check the equipment danger. First, water leakage may occur during the cooling process of the chiller: For small chiller refrigeration systems, the condenser is usually used to regulate and store the refrigerant instead of the liquid tank-this is not used by the chiller The normal phenomenon is the inspection method caused by improper installation.

The chiller should be tested immediately after installation. Refrigeration... Before installing the refrigerator, we check all parts-refrigeration low-temperature brine chiller, low-temperature chiller, in order to improve production efficiency, improve product quality and reduce production The requirements for temperature control in the cost production process are getting higher and higher-these liquids can be used to cool air or equipment through heat exchangers-the first imported foreign advanced technology can be digested and absorbed in time. In order to avoid losing parts during transportation, if it is found that this is a manufacturing The supplier’s responsibility is necessary to issue replacement parts and then if the shipping company has a problem causing the parts to be lost, the shipping company shall be responsible according to the agreement. If there is no leakage of water droplets after a period of operation, the water leakage problem will basically not happen?
