What if the maintenance pressure of Roots blower is low?

Roots blower is a centrifugal fan commonly used in the industrial field, which is widely used in air compressors, gas conveying equipment, etc. However, in the process of using Roots blower, we sometimes encounter the problem of low maintenance pressure. This article will focus on this topic, introduce the reasons and solutions for low maintenance pressure of Roots blower.

1、 Introduction

Roots blower is an important industrial equipment, which is widely used in various industries.

However, in the process of use, we sometimes encounter the problem of low pressure, which brings troubles to work efficiency and production schedule.

Therefore, understanding the causes and solutions of low maintenance pressure of Roots blower is of great significance for normal operation of equipment and improvement of production efficiency.

2、 Cause analysis

1. The fan impeller is damaged

The impeller of Roots blower is a rotating part of the blower. If the impeller is damaged or deformed, the pressure of the blower will drop.

Common causes of impeller damage include wear, corrosion, fatigue, etc.

When the impeller is damaged, it needs to be replaced or repaired in time to restore the normal operation of the fan.

2. Excessive air inlet resistance

Excessive inlet resistance of Roots blower will also lead to pressure reduction.

The reason for excessive air inlet resistance may be the blockage of air inlet, failure of air inlet valve or pipeline leakage.

During maintenance, it is necessary to carefully check the air intake system, clean the blockage, replace the failed valve or repair the leakage problem to restore the normal air intake flow.

3. Excessive exhaust resistance

Excessive exhaust resistance of Roots blower will also lead to pressure drop.

The reason for excessive exhaust resistance may be that the exhaust pipe is blocked, the exhaust valve is invalid, or there are too many elbows at the fan outlet.

During maintenance, it is necessary to check the exhaust system, clean the blockage, replace the failed valve or optimize the layout of the exhaust pipe to reduce resistance.

4. The running speed of the fan is unstable

The unstable running speed of Roots blower will also lead to low pressure.

The unstable running speed may be caused by motor fault, transmission system problem or control system failure.

During maintenance, it is necessary to check the motor, transmission system and control system, and carry out corresponding maintenance or adjustment to ensure that the operating speed of the fan is stable.

3、 Solution

1. Timely repair the impeller

When the impeller of Roots blower is damaged, it needs to be repaired or replaced in time.

When repairing the impeller, welding, heat treatment and other methods can be used to ensure that the structure and performance of the impeller return to the normal level.

If the impeller cannot be repaired, it is necessary to replace the impeller in time and select the appropriate impeller model and material to ensure the normal operation of the fan.

2. Clean the air intake system

When the intake resistance of Roots blower is too large, it is necessary to carefully check the intake system and clean the blockage.
