How Do Positive Displacement Blowers Work?

The working of positive displacement blowers is similar to rotary vane blowers. Two impellers or rotors are joined using gears surrounded by a blower casing. When the blower is in operation, the blades rotate at the same speed, but in different directions. This causes the blower to trap gas on the inlet, and as the lobes start rotating, push the gas from the outlet. The volume of the gas does not change even if it travels around the periphery of the lobe chamber from the inlet to the outlet. The volumetric flow depends on the speed of rotation and size of the chambers.

Why Invest in Used Positive Displacement Blowers?

Investing in used industrial equipment benefits in many ways. Here are a few pointers regarding the same.

How to Maintain Positive Displacement Blowers?

Taking good care of positive displacement blowers is important to keep them operational, and increase their lifespan. The following are some common ways to maintain your positive displacement blowers. So, let’s take a look at them.

  • The first and foremost important thing is to check whether the blower has enough lubricating oil. The oil should be changed after a specific range of operations. If not, it will cause premature wear on the gears.
  • Next, make sure the blower can handle the required pressure to accomplish the job. If the relief valve on the machine is not enough, there is a high chance of warping of the rotors. This would lead to serious damage if it comes in contact with other parts of the machine. So, choose the blower wisely considering your application requirements.
  • Undoubtedly, dirt is going to accumulate over a period of time as the blower runs. Once it builds up on layers, it can cause excess drag on gears and other moving parts. This may lead to failures or replacements. Therefore, clean the blower after fixed time periods to prevent internal damage.
