What is the cause of refrigerator compressor not working

What is the cause of refrigerator compressor not working Ambient temperature is too low: it is more difficult to recover, the compressor cannot work for a long time, the compressor oil becomes thicker, and the lubrication performance will be worse; PTC starter failure: if the PTC starter is damaged, you can replace it Overload protector failure: failure occurs, replace it; compressor internal failure: determine that the compressor holds the shaft and replace it. We know that the refrigerator is an indispensable appliance in the home. Due to the high frequency of use, it will be prone to some failures after a long time. At this time, we must find the cause and deal with it. The following editor will introduce the reason why the refrigerator compressor does not work. 1. The ambient temperature is too low

a. If the ambient temperature is at (1～10℃), then you need to open the compensation switch at this time, and you need to check whether the magnetic switch is normal: to know that the temperature may be too low, especially for some dual-temperature single-control refrigerators As long as the working time is too short and its refrigerating temperature reaches (1～10℃) degrees, then the temperature will be more difficult to rise in this case, the compressor cannot work for a long time, and the shutdown may be too long , It may cause non-working. b. When the ambient temperature is 0 ℃, then you must stop using the refrigerator: when the temperature is 0 ℃, this time may make the compressor oil thicker, the lubrication performance may be worse; at the same time It is possible that the condensing pressure will also decrease, and the refrigerant will flow into the evaporator. 2. Failure of the PTC starter

You can use a multimeter to measure the PTC starter. At this time, you can see whether its running jack and start jack are normal. If the PTC starter is damaged, you can replace it. 3. Overload protector failure

You can use an ammeter to measure the compressor startup, and also check the running current. If the current exceeds the action of the protector, there may be a malfunction and it should be replaced. 4. Internal fault of the compressor

If the testing of the compressor accessories is normal, but the compressor still cannot be started at this time, then you may have too much starting current during the measurement. At this time, you can judge it as the compressor holding the shaft. In this case It is necessary to replace the compressor.

Why is the air conditioner not cooling

Why is the air conditioner not cooling There are many factors for not cooling, for example: the selected air conditioner does not match the area of the room; improper installation of the air conditioner will cause the air circulation of the air conditioner to be unsmooth; when the indoor temperature is relatively high, the air conditioner cannot be cooled when turned on; It has been aging, or the service life has expired; the air conditioner has not been cleaned for a long time, and the filter surface is covered with dust; and the freon of the air conditioner has been seriously lacking. <img src="{{media url="magefan_blog/Why_is_the_air_conditioner_not_cooling.jpg"}}" alt="" />

What's the matter with air conditioning and cooling without heating

What's the matter with air conditioning and cooling without heating 1.First, it may be because the vents of the indoor unit and outdoor unit are blocked by something, or a lot of dust has accumulated on the filter inside the air conditioner; 2. It may be because the heat blown from the air conditioner is seriously lost; 3 2. It may be because the amount of refrigerant in the air conditioner is too small, which leads to a great reduction in the heat exchange efficiency, so that the air conditioner does not heat. <img src="{{media url="magefan_blog/What_s_the_matter_with_air_conditioning_and_cooling_without_heating3.jpg"}}" alt="" />

Working principle of steam compressor_steam compressor application Working principle of steam compressor After the steam is filtered by the filter, clean steam then enters the host cavity through the intake valve, and the volume of the cavity changes from large to small to compress the steam. The volume of the cavity is changed by the rotor rotating under the drive of the motor. <img src="{{media url="Working_principle_of_steam_compressor_steam_compressor_application.jpg"}}" alt="" />

Single-stage high-speed centrifugal blower This type of steam compressor is a relatively common steam compressor on the market. It can have a large air volume and pressure and can meet the needs of many working conditions. The single-stage high-speed centrifugal blower is designed with a ternary flow theory, and the whole structure of the fan is compact , And the technology is relatively mature. 2.

The difference between centrifugal compressor and reciprocating compressor Centrifugal compressor overview 　　 Centrifugal compressor is also called "vortex compressor", a type of compressor. The structure and operation principle are similar to the centrifugal blower, but it is always multi-stage, which can make the gas obtain higher pressure, larger processing capacity and higher efficiency.<img src="{{media url="The_difference_between_centrifugal_compressor_and_reciprocating_compressor.jpg"}}" alt="" />

Common failure and analysis of centrifugal air compressor 1. Abnormal vibration and noise: ① Misalignment ② The compressor rotor is unbalanced ③ The impeller is damaged ④ The bearing is abnormal ⑤ The coupling is faulty or unbalanced ⑥ The sealing ring is bad ⑦ The oil pressure and oil temperature are abnormal ⑧ There is dirt in the oil Clean, wear out the bearing ⑨ Surge ⑩ The stress of the gas pipeline is transmitted to the casing, which causes misalignment ⑪ There is a machine working near the compressor<img src="{{media url="Common_failure_and_analysis_of_centrifugal_air_compressor.jpg"}}" alt="" />
