With the development of gear pump to the direction of high pressure, high speed and high precision, the influence of oil pollution on the wear life of high viscosity stainless steel pump is more and more prominent. Leakage inevitably brings pollution, and pollution wear leads to increased leakage in the oil pump.
In some cases, even trace pollution can produce serious wear on the gear pump, and then increase the pump leakage, volume efficiency and loss of performance.
The wear pollution sensitivity test was carried out on the gear pump wear test device, and on this basis, the interaction between leakage and contamination wear was discussed, which provided reference for reducing the leakage in the gear pump and improving its service life.
(1) Smooth conveying liquid, no pulsation, small vibration, low noise.
(2) have strong self-priming performance.
(3) The correct selection of parts materials, can transport a variety of corrosive media, the use of temperature up to 200℃.
(4) the inner and outer rotor steering is the same, small wear, long service life.
(5) The speed and flow is a linear function, and the speed can be appropriately changed to change the flow of the pump.
(6) Especially suitable for conveying high viscosity medium.
