Vacuum Pumps

For truck-mounted hydraulic systems, the most common design in use is the gear pump. This design is characterized as having fewer moving parts, being easy to service, more tolerant of contamination than other designs and relatively inexpensive.

This complexity falls to the equipment designer and service technician to understand in order to ensure the piston pump is working correctly with its additional moving parts, stricter filtration requirements and closer tolerances.

Rotary vane: Rotary vane pumps are comprised of a series of vanes that are mounted to a rotor that turns inside a cavity. As the vanes rotate, centrifugal force extends them from their individual slots, forming compression cells that get larger to draw air in from the intake and smaller to push air out the exhaust.

A vacuum pump is a device or device that USES mechanical, physical, chemical substance or physical-chemical strategies to pump air out of a container to get a vacuum.

The air vacuum pump is a venturi-type AC pump that eliminates moisture from air conditioning systems, making it safe and easy to add refrigerant.

Whereby the pump chamber fixed volume of air compression (compression suction port is closed, the exhaust port is formed to open slightly positive pressure), stretching (compressed exhaust port is closed, a negative pressure sucking mouth open), the pumping air intakes with the outside atmospheric pressure difference, at a pressure difference, the gas pressure (suction) into the pump chamber, and discharged from the exhaust port.
