Heat Pump Compressor Troubleshooting

There are various types of compressors used in the heat pump unit and the fully enclosed piston compressor is the most commonly used type. However, when it’s in winter, there most probably are faults of this type of compressor due to frequent heating operations.

Maintenance of screw air compressor

1. Maintenance of intake air filter element. The air filter is a component that filters out air dust and dirt. The filtered clean air enters the compression chamber of the screw rotor for compression. Because the internal clearance of the screw machine only allows particles within 15u to filter out.

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=&quot;magefan_blog/What_s_the_matter_with_air_conditioning_and_cooling_without_heating3.jpg&quot;}}" alt="" />

Compressed air filter classification and applicable occasions

Compressed air filter is a device for filtering and purifying compressed air. Generally, the compressed air filter element is composed of fiber media, filter mesh, sponge and other materials. The solid and liquid particles (drops) in the compressed air are intercepted by the filter material and condensed on the surface (inside and outside) of the filter element.

Discussion on Reasons and Protection of Air Compressor Motor Damage

Air compressor is abbreviated as air compressor. As a general-purpose mechanical equipment, it is widely used in the field of industrial and agricultural production. The problem is that the motor (three-phase asynchronous motor) as the power equipment of the air compressor generally has a higher failure rate than other motors.
