(Summary description)The compressor is a driven fluid machine that promotes low-pressure gas to high-pressure gas. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle.

Information

The compressor is a driven fluid machine that promotes low-pressure gas to high-pressure gas. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. So what are the reasons for the lack of exhaust? Let's follow the editor of Electric compressor air cooling SEF140 to have a simple understanding!
1. Malfunction of the air intake filter: fouling and clogging, reducing the exhaust volume; the suction pipe is too long and the pipe diameter is too small, resulting in an increase in the suction resistance and affecting the air volume, so the filter should be cleaned regularly.
2. The reduction of the compressor speed reduces the displacement: the air compressor is used improperly, because the displacement of the air compressor is designed according to a certain altitude, suction temperature and humidity, when it is used in a condition that exceeds the above standards When on the plateau, the suction pressure decreases and the exhaust volume will inevitably decrease.
3. The cylinders, pistons, and piston rings are severely worn and out of tolerance, which makes the relevant gaps larger and the leakage volume larger, which affects the exhaust volume. When it is under normal wear, the wearing parts, such as piston rings, need to be replaced in time.
4. The stuffing box is not tight, causing air leakage and reducing air volume. The reason is that the stuffing box itself does not meet the requirements when it is manufactured; secondly, it may be due to poor alignment of the piston rod and the stuffing box during installation, resulting in wear, strain, etc., causing air leakage; generally, lubricating oil is added to the stuffing box. Can play the role of lubrication and sealing.
5. The spring force of the air valve is not well matched with the air force. If the elastic force is too strong, the valve plate will open slowly, and if the elastic force is too weak, the valve plate will not close in time. This not only affects the air volume, but also affects the increase in power and the life of the valve valve plate and spring. At the same time, it will also affect the changes in gas pressure and temperature.
The above is the introduction of Electric compressor air cooling SEF140 editor: about the reasons for the insufficient displacement of the compressor, I hope you can learn more through the introduction of the above editor.
