doosan excavator hydraulic pump

As one of the "three major parts" (engine, cat 330 hydraulic pump, distribution valve) of an excavator, the "cat 330 hydraulic pump" can be regarded as an energy conversion device more often, which converts the mechanical energy from the engine into hydraulic energy, for The hydraulic system provides a certain flow of pressure oil to drive the hydraulic cylinder and hydraulic motor. It can be said that the hydraulic pump is the power source of the entire hydraulic system.

The cat 312 hydraulic pump is supplied with oil by the main pump driven by the engine. The main pump is divided into an upper pump and a lower pump, both of which are swash plate type plunger pumps. There is a main pump regulator behind each main pump. By changing the effective stroke of the plunger to the main pump, the displacement increases or decreases, that is, the power absorption capacity of the main pump is increased or decreased.

The main business of komatsu pc300 hydraulic pump are: komatsu pc300 hydraulic pump, distribution valve, self-pressure regulating valve, pilot valve, valve block, rotary reducer, rotary motor, rotary solenoid valve group, Komatsu hydraulic oil tank, hydraulic pump assembly, hand oil pump, distribution Valve assembly, grease fitting, rotary reducer, rotary reducer assembly, Komatsu series oil cylinder assembly, hydraulic pump nine-hole disc, etc. The komatsu pc300 hydraulic pump sold by the company have many varieties and specifications. The main function of the Komatsu hydraulic parts is to drive the driving power and working power of the machinery. The structure of the Komatsu hydraulic parts is cumbersome and complicated. The company generally adopts rolling bearings or static pressure. Manufactured by sliding bearings, Komatsu hydraulic parts can only be started mechanically when they are in operation. The rotational inertia of Komatsu hydraulic parts is small, it is more convenient to start and brake, and its adjustment and reversing sensitivity is high.

What should I do if the excavator walks slowly and deviates? - Check the kobelco sk60 hydraulic pump! What should I do if the digging motor does not move and the car is seriously stuck? - Check the hydraulic pump! What should I do if the whole vehicle of the excavator moves slowly or does not move at all when it is serious - check the hydraulic pump!

The doosan excavator hydraulic pump is the power component of the hydraulic system, its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of doosan excavator hydraulic pump generally include gear pumps, vane pumps and plungers.

hitachi hydraulic pump maintenance instructions When the hitachi hydraulic pump of the excavator is first used, pay attention to whether the pump has abnormal noise? Because it is easily affected by air bubbles and dust at the beginning of operation, poor lubrication at high temperature or overloading of conditions, etc., make the hydraulic pump emit abnormal sound. Pay attention to the displayed value of the pressure gauge of the hydraulic circuit of the excavator at any time. Understand the function of each valve inside the hydraulic pump system of the excavator. The speed of the hydraulic pump is also related to the control pressure. The control pressure comes from the valve group, with positive control and negative control. The positive control oil pressure signal comes from the differential pressure, the higher the pressure, the greater the hydraulic pump flow, which is a proportional signal.

Excavator Hitachi ex100 hydraulic pump installation precautions (1) Ensure that the hydraulic oil is very clean The hydraulic oil directly enters the Hitachi ex100 hydraulic pump. If there are impurities in the hydraulic oil, the structures such as the plunger and the distribution plate will be worn, causing damage to the hydraulic pump, and even the hydraulic pump will be scrapped! Therefore, the hydraulic oil filter must be a genuine filter. Generally, the higher the density of the filter, the better the quality of the filter! (2) After the Hitachi ex100 hydraulic pump is installed, there is no hydraulic oil, and it is strictly started. It is necessary to add hydraulic oil to the oil return pipe. (3) Pay attention to the discovery of abnormal phenomena at any time Abnormal sounds, vibrations, or abnormal signals of the monitoring system must have their reasons. When an abnormal phenomenon is found, immediately find the circuit diagram, follow the diagram to find out, and carefully observe whether the abnormal phenomenon is caused by a temporary error. Assess the need for parking. For example, pressure, load, temperature, time, start-up, and stop all include the reasons that may cause abnormal phenomena. Usually, it should be analyzed and discussed item by item.
