China Vane Pump , Various Vane Pumps: Main Features
Among the vane pumps used, there are various types of vane pumps, and their main features are also different. The China Vane Pump introduces the main features of different types of vane pumps.
The main features of jbj technology vane pump
All wearable parts are contained in a cassette unit that can be easily removed for inspection and/or replacement without disconnecting the pump from the circuit, greatly reducing expensive machine downtime.
The box contains the rotor, vanes and inserts, cam ring and two covers.
During operation, the rotor is driven by a splined shaft that is connected to the drive unit. As the rotational speed increases, the centrifugal force combines with the pressure generated behind the blades to push the blades outward, where they follow the contour of the cam of the ring with sufficient contact pressure to ensure a sufficient hydraulic seal.
The two opposing pumping chambers formed by the elliptical profile of the cam counteract the radial loads on the bearings, giving them an extremely long life.
The versatility of the BV series pumps makes them suitable for a wide range of industrial applications. In fact, they have a particularly low noise level in addition to proven high reliability and excellent volumetric efficiency under all operating conditions.
This can be achieved by the special profile of the cam ring and the use of a 12-bladed rotor that reduces the amplitude of the supply pressure pulse, thereby reducing the induced vibration.
Fixed displacement high pressure hydraulic vane pump
The two opposing pump chambers formed by the elliptical profile of the cams within the cartridge eliminate radial loads on the bearings, giving them an extremely long life.
The special design of the lip blades makes the BD series pumps particularly suitable for applications requiring high pressure levels and very low noise emissions.
»Three models of single pumps (10 to 227 l / min, 1000 rpm)
» Four models of dual pumps (20 to 385 l / min, 1000 rpm) with input power exceeding 328 kW at maximum pressure and speed.
The BD series pumps are very compact and come with SAE standard hydraulic flanges and shafts. This makes them very easy to install and guarantees their interchangeability with other similar pumps.
Fixed displacement high pressure hydraulic vane pump
The special design of the lip blades makes the HD series pumps particularly suitable for applications requiring high pressure levels and very low noise emissions. In addition, the two opposing pump chambers formed by the elliptical profile of the cam counteract radial loads, significantly reducing vibration and significantly increasing pump life.
In addition to reliability, the HD pump guarantees consistently high volumetric efficiency throughout the entire service period. This avoids having to compensate for the typical efficiency losses of other types of pumps, increasing the truck engine RPM, which results in higher fuel consumption and therefore air pollution. These features, along with extremely low noise levels, make HD pumps environmentally friendly and meet modern ecological needs.
Single pump (11 to 99 l / min, 1000 rpm)
Double pumps (from 22 to 200 l/min at 1000 rpm) with maximum power of over 126 kW at maximum pressure and speed.
These pumps are very compact and offer different types of ISO or UNI standard mounting for direct connection to PTO and SAE standard hydraulic fittings. This, along with the ability to position the inlet and outlet, makes the HD pump very easy to install and ensures interchangeability with other types of pumps.
