What Are the Reasons for Insufficient Air Output of Screw Air Compressors?

2025-01-07

The air output of a screw air compressor directly affects the operating efficiency of the equipment. When the air discharge volume drops, how should we deal with it? Generally, the first step is to find out the cause of the failure, and then conduct inspections and repairs. Today, we will introduce how to reduce the air discharge volume and solve failure problems.

Intake air filter
First, check the water inlet filter. If the intake air filter is fouled, it will reduce the flow rate. If the suction pipe is too long and the vent pipe is too small, the suction resistance will increase, affecting the air volume. Therefore, the filter needs to be cleaned or replaced regularly. Severe wear of the cylinder, piston, and piston rings will increase the clearance and leakage, affecting the exhaust. So when wear is detected, vulnerable parts such as piston rings should be replaced in a timely manner.
Air valve spring
The force of the air valve spring does not match the gas force well. If the valve plate is too elastic, the valve plate will open slowly, and if the elasticity is too weak, the valve plate will not close in time. This not only affects the air volume of the screw air compressor but also increases the power consumption and affects the service life of the air valve plate and spring.
Maintenance of the air compressor
When using a screw air compressor for a long time, it is necessary to do a good job in the maintenance of the air compressor, that is, some vulnerable parts need to be replaced in advance. For example, the repair kit for the air intake valve of the air compressor.
The air compressor controls the opening of the air intake valve of the cylinder through a solenoid valve, and the screw air compressor sucks in air and enters the loading state. At this time, the air compressor starts to work, but if the air intake valve does not open, the air compressor will not work properly. The accessories of different air compressors vary greatly. Many enterprises do not have a sufficient understanding of the performance of some parts of the air compressor when purchasing it. Some equipment is not suitable for use in cold climates. When this part of the air compressor operates in an unsuitable environment, it will cause frequent failures of the air compressor. This is not a quality problem of the equipment itself but is caused by unprofessional selection.
Therefore, when purchasing air compressor equipment, it is necessary to find a professional screw air compressor manufacturer.

When a screw air compressor is operating, it must have a certain air pressure and sufficient air production volume to ensure stable production. Therefore, we generally recommend choosing a screw air compressor, which has the characteristics of stable performance, low vibration, low noise, economical installation, and low maintenance costs.
