Do you know how to use vane pumps work?
The vane pumps are mechanical volumetric pumps, framed within the category of hydraulic pumps, as well as gear pumps and piston pumps. These types of pumps allow the transformation of mechanical energy into hydraulic. A common feature to all hydraulic pumps is that the system does not generate pressure, but rather it derives from the resistance to flow. In this article we show you some clues to understand how these vane pumps work, their main applications and the advantages that can make for your company respecting to other types of industrial pumps.
Performance of the vane pumps
The performance of vane pumps is based on radial kinematics. Vane pumps are composed of a circular housing, inside within a ring that rotates eccentrically relative to a rotor. The rotor has slots, inside which the vanes are placed, moving radials with alternative movements.
When the engine is running, the increase of the chamber or space enclosed between the paddles, the rotor and the casing creates a vacuum. The atmospheric pressure derived from that vacuum drives the fluid into the pump. When this gap is reduced, the liquid is impelled outwards, through the discharge port.
This stem differs to the vane pump from the gear pump, in which we find two gears coupled inside the pump body. This pair of gears is composed in turn of a driving shaft, driven by the motor shaft, and a driven shaft. When the gear pump is in operation, the drive shaft rotates the driven one by the displacement generated by the contact between the teeth of the shafts and the teeth of the gears.
Types of vane pumps
Within the type of vane pumps, we can differentiate between balanced and unbalanced vane pumps. Unbalanced pumps can be classified into fixed or variable displacement pumps. On the other hand, balanced vane pumps are characterized by a fixed displacement design.
The type of vane pumps is extensive, with different characteristics and features. If you are looking for the most suitable vane pump, it is advisable to have the advice of a specialized manufacturer in this type of industrial machinery, which can adequately evaluate the model that best adapts to the needs of each specific case.
Uses and applications of vane pumps
Vane pumps have very diverse applications, among which we can highlight:
- Transfer of products within the oil, chemical or textile industry
- Water transfer in cooling installations
- Food processing
- Lubrication of machinery
- Oil cleaning in closed circuits or emptying of industrial fryers
- Printing and packaging machines
- Hydraulic circuits for earth moving machines
Vane pumps offer a variable work volume, which can be adapted to the speed of rotation and viscosity. This type of pumps stands out for their ability to transport high viscosity products. Its high resistance to contaminants and chemical agents makes vane pumps indicated to work in corrosive and aggressive environments. Among its main advantages, its long useful life stands out, provided that periodic reviews are made. In addition, its maintenance is quick and easy from the technical point of view.
