ZF Hydraulic & Pneumatic Parts Co., Ltd

1 efficient, high pressure under the steady rotation: special pressure control mechanism and force balance mechanism, the cam ring is supported on three points, increase pressure to rotate with the performance, but also under 140bar can play an efficient performance.

2 no vibration, no noise: adopting several kinds of sound insulation, vibration of new institutions, especially reliable rotation of the cam ring stability. A control piston, a piston is formed by special three points supporting, reduce the vibration of rotating cam ring, no noise.

3: a new sensitive response, high precision of the cam ring control mechanism, a cam ring without displacement, thus improve the reaction sensitivity to start, stop, load changes will not change the precision.

4 sensitive characteristics, flow rate stability: a new pressure balance type pressure control mechanism, under high pressure flow can also be highly smooth.

5 rotate with high efficiency, reduce energy loss : the new mechanism to reduce the loss of energy, especially the high wheel out of the state, the more obvious the energy loss is reduced.

The 6 maintenance, easy maintenance: pressure adjustment mechanism and flow adjustment mechanism is placed on the same side, will put the maintenance and adjustment.

Pump with high working pressure, can reach 275Bar, such as the use of reduced working pressure, but also can extend the working life of the pump! High volumetric efficiency, which increases productivity, reduces heating and reduces operating costs for hydraulic equipment. Mechanical efficiency is high, thus reducing the energy consumption. Wide speed range, speed range is 600-- --2800rpm, can optimize the working state, reduce noise. Anti-pollution ability is strong, denison oil pump is the use of double-lip structure of the blade, with a strong anti-pollution ability, long service life. Suitable for hydraulic medium viscosity range, can start at low temperature and high temperature operation, can provide high pressure, low noise, and high volume efficiency.

Vane pump according to the different working principle, can be divided into centrifugal pump, axial pump and mixed flow pump three categories. (1) centrifugal pump. According to its basic structure and form characteristics, it is divided into single-stage single-suction centrifugal pump, single-stage double-suction centrifugal pump, multi-stage centrifugal pump and self-priming centrifugal pump. (2) axial flow pump. According to the direction of the spindle can be divided into vertical pump, horizontal pump and inclined pump; According to the blade adjustable Angle can be divided into fixed, semi-adjustable and fully adjustable type. (3) mixed flow pump. According to the structure, it is divided into volute type and guide vane type.

Generally speaking, the application environment of walking equipment such as construction machinery is often very harsh. The foreseeable situations include sharp temperature difference, long load cycle, dirty and messy environment, changeable terrain and other emergencies. To cope with so many challenges, users need reliable, efficient, durable, low maintenance rate of the machine, otherwise, frequent failure will not only cost expensive maintenance costs, but even delay the project or lead to production halt.
