The positive displacement blower, which moves gas or air, is perhaps the most underappreciated part of your hydrovac truck. They are usually highly effective. Why mend something that isn’t broken in the first place? This can only be answered by hydrovac contractors who offer hydrovac services in Colorado.

This mentality is frequently what costs vacuum truck owners a lot of money. Positive displacement blowers, like any other piece of machinery, are subject to wear and tear if not properly maintained. When it fails, work effectively comes to a halt.

Of course, you should always read the operating instructions to make sure you know what to do if your blower breaks down. 

How to keep your positive displacement blower in good working order

1. Overhung Load

Excessive overhung load is a typical and often overlooked cause of drive shaft spinning equipment failure, so keep an eye out for it. A positive displacement blower’s rotors are an important component.

The drive shaft bearing, which bears the weight of side loading, suffers the most damage from excessive overhung load. This can be transmitted to the gears via the rotors. Massive wear and strain, as well as possible gear and bearing failure, are the ultimate results. In other words, your positive displacement blower could be permanently ruined.

Excessive drive shaft loading is another thing to watch out for. This can cause the rotors to collide, causing the blower to shudder and grind to a halt.

2. Lubrication 

Lubrication is required for any machinery to function properly. Bearings and timing gears in positive displacement blowers must be kept greased at all times. There’s also the risk of using too much or too little lubricant, so study the handbook to determine the appropriate levels.

The manual and hydrovac contractors will also tell you how much oil you need and what viscosity and quality of lubrication is optimal for the blower. Putting the wrong kind of oil in a gasoline-powered car, for example, might cause catastrophic damage. Synthetic lubricants are recommended for your blower’s gears and gear end bearings as a general rule.

3. Tension

Over-pressure concerns caused by a defective relief valve in your blower can significantly harm the rotors. Over-pressure can cause rotors to collide with one another, the cylinder, and possibly the blower’s head plates. To avoid having to pay the price later, ensure the relief valve is the right size and properly installed. You might also install a pressure release valve to ensure that there are no difficulties with over-pressure.

4. Vibrations

Smooth vibrations should be produced by your blower. When you have too much, you know something is amiss. Perhaps something within has fallen loose. A bouncing element in your blower could cause all of its components to fail. Consider a rattling stone in a container. Something is wrong if you hear or feel an unpleasant sound or vibration. Stop the equipment and inspect it right away.

5. Employee Education

While service facilities are always open, it may take some time for your broken blower to be repaired and returned. Routine maintenance requires time as well. It’s usually a good idea for staff who will be managing this critical piece of equipment to understand how each component of the blower works. This can save time and money since an employee who understands how the blower works is more likely to maintain it properly.

To wrap

A blower is not a particularly difficult piece of machinery. All you have to do is keep your eyes and ears open for anything unusual, and your blower will offer consistently excellent results. Before putting your blower to work, give it a daily check.
