Vacuum Truck Sale

When looking for a vacuum truck sale to purchase one of these powerful vehicles, it is important to know how to recognize if the truck has been properly equipped. In its most basic form, a vacuum truck has a powerful pump that suctions air through a hose and then a tank in order to collect debris and deposit it into the tank just as a household vacuum operates. Of course, these trucks are very large in comparison and can be dangerous if problems occur and be costly to repair. So it is it important to correctly equip a vacuum truck to ensure safety.

Here are some of the problems that could occur if a vacuum truck lacks the right safety equipment.

  • Implosion – Implosion occurs when the holding tank collapses from a buildup of high negative pressure that can happen when the pump removes so much air or the suction hose gets blocked with the pump running. The negative pressure buildup will eventually cause an implosion and damage the tank.
  • Explosion – During unloading, the pump reverses to allow pressure to build up in the tank for easy debris removal. If pressure exceeds tank capacity because of a blockage, an explosion could happen.
  • Pump Damage – The pump can extract large amounts of air in seconds and yet is a very delicate part of the equipment. The vanes can easily be damaged if debris gets through the tank and into the pump, which would be very costly to repair or replace.
  • Overfilling – The holding tank can only hold a limited amount of solid and liquid debris; beyond that capacity, any excess can reach the pump and cause damage. As the tank fills, performance decreases which causes the pump to work harder to get air past the debris.

To protect the equipment and ensure a safe operation, there are several safety features that are built in.

  • Primary Shutoff – This on-and-off device provides the main protection to the pump from debris; it is located farthest from the inlet port at the top of the tank. This location allows debris to lose velocity when entering the tank and allows gravity to keep it from getting into the device. It has a floating ball that automatically closes the hole when the tank fills to prevent debris from reaching the pump.
  • Secondary Shutoff – This is a secondary line of protection from incoming debris as there are times when small particles and moisture still gets past the primary shutoff because of the powerful suction created by the pump. It serves as an additional level of pump protection.
  • Vacuum/Pressure Relief – These are two separate safety vales located at the top part of the holding tank. The vacuum valve opens up when the negative pressure exceeds safe levels to prevent an implosion. The pressure valve opens up when the pressure exceeds safe levels to prevent explosion.
  • Oil Catch Muffler – Removing massive amounts of air generates a lot of noise and oil, which requires the use of an oil catch muffler. It serves two purposes: dampening the noise generated by the pump to tolerable levels and catching the oil that is used to lubricate the pump in order to prevent spilling.

When looking for a vacuum truck sale, knowing how one should be properly equipped to operate safely is vital. Applying this knowledge to a vacuum truck should ensure safe operations and effective, productive usage!
