High quality and high standard excavator hydraulic pump, strong factory strength, complete factory assembly line, professional engineers, to ensure the high quality of production, but also to provide a very strong after-sales service.
This pump made in iron alloy . it is high weight so that it can withstand the high pressure . in this way it will have a long warranty.
this pump is common in the market , so that the price is good , and my pump is factory outlet,the price will cheaper than others .
The gear pump of a wheeled excavator (wheel excavator) is a key power element in its hydraulic system. Its working principle and function are as follows:
1. Working principle
The core of the wheel excavator gear pump is to achieve oil suction and oil pressure through the periodic change of the volume between the teeth when a pair of meshing gears rotate. The specific process is:
1. Oil suction: The active gear (driven by the engine) drives the driven gear to rotate in the opposite direction. On the side where the gear is disengaged (the oil suction chamber), the tooth groove volume increases to form a local vacuum, and the hydraulic oil in the tank is sucked into the tooth groove under the action of atmospheric pressure;
2. Oil pressure: The gear continues to rotate, and the oil in the tooth groove is brought to the meshing side (the oil pressure chamber). At this time, the gear enters the meshing, the tooth groove volume decreases, and the oil is squeezed out, and hydraulic oil with a certain pressure is output (usually medium and low pressure, adapted to the needs of wheel excavator walking, steering and other actions).
The whole process relies on the precise matching of the gear, the pump body and the end cover to form a sealed space, and the conversion of mechanical energy to hydraulic energy is completed through volume changes.
2. Main functions
1. Provide hydraulic power: provide pressure oil for the key actions of wheel excavators, including:
- Travel system: drive the wheel side motor to realize the whole machine forward, backward or steering;
- Auxiliary actions: such as boom lifting, bucket flipping and other light operation actions (in some wheel excavators, the gear pump may cooperate with the main pump to share the load);
- Steering system: provide power for the hydraulic steering cylinder to achieve flexible steering (wheel excavator steering relies on hydraulic power assistance, and gear pumps are a common power source).
2. Adapt to the characteristics of wheel excavators: gear pumps have a simple structure, low cost, strong anti-pollution ability, suitable for complex environments where wheel excavators often operate on unpaved roads, and easy maintenance.
3. Optimize system efficiency: as a medium and low pressure pump, it can be responsible for low-load actions such as walking and steering alone, avoiding excessive power consumption of the main pump (if any), and improving the fuel economy of the whole machine.
In short, the wheel excavator gear pump is a "hydraulic power source" that drives walking, steering and some operation actions. With its structural advantages, it adapts to the working conditions of wheel excavators and ensures flexible operation of the whole machine.
