P30 gear pump：technical analysis of high pressure output and efficient flow rate

Whether it is the hydraulic lifting of construction machinery or the precise control of automated production lines, the high-pressure output capacity and high-efficiency flow characteristics of gear pumps play an irreplaceable role. In this article, we will take p30 gear pump as an example and analyze the technical mystery of gear pumps from these two key features.

1. Mechanical mystery of high pressure output

The core of the gear pump to realize high-pressure output lies in its innovative volume change mechanism. When the active gear drives the follower gear to rotate, the gear meshing area forms a sealed working chamber. In the suction chamber, the gears disengage and mesh to increase the volume to form a vacuum, and the liquid is filled under atmospheric pressure; after entering the pressure chamber, the gears re-engage to reduce the volume dramatically, and the liquid is strongly squeezed. This cyclic volume change produces a strong output pressure, enough to drive the hydraulic actuator of heavy construction machinery.

2. Continuous transportation guarantees efficient flow

The high efficiency of the p30 gear pump stems from its continuous and smooth flow output mechanism. In contrast to the pulsating oil supply of piston pumps, at least two pairs of teeth work simultaneously during gear meshing, resulting in uninterrupted fluid delivery. This characteristic brings three core advantages:

(1) Energy saving

By optimizing the tooth parameters, the flow pulsation coefficient of a certain type of pump has been reduced from 8% to 2%, which, together with the double-module asymmetric gear technology, has resulted in 15% energy saving in the hydraulic system of an injection molding machine.

(2) Wide viscosity adaptability

A polar research equipment using low-temperature gear pumps, in the -50 ℃ environment can still be stable delivery of antifreeze viscosity up to 3000 cSt.

(3) High-speed response characteristics

An automated production line application case shows that its commutation response time is 40% faster than that of a vane pump, and productivity is increased by 22%.

3.Innovative applications

In the field of new energy, an electric vehicle hydraulic steering system using lightweight aluminum alloy gear pumps, weight reduction of 40% at the same time, through the teeth of the DLC coating technology to increase the working pressure to 28MPa; in the deep-sea equipment, special stainless steel gear pumps with a double mechanical seal structure, the success of the 3,000-meter depth environment to achieve 6,000 hours of continuous trouble-free operation.

These breakthroughs stem from advances in material science and manufacturing processes, the future, the performance of the gear pump will continue to expand the boundaries for industrial equipment to provide a more powerful “hydraulic heart”.
