hyundai 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.

1) Function and role of komatsu pc200 hydraulic pump The hydraulic pump is also called the working pump, commonly known as the main pump. The hydraulic pump is an energy conversion device that converts the mechanical energy from the engine into hydraulic energy, providing Supply a certain flow of pressure oil to drive the hydraulic cylinder and hydraulic motor, which is the power source of the entire hydraulic system. The hydraulic pump is mainly composed of shell, cylinder block, plunger, swash plate, valve plate, slide plate, drive shaft, servo piston, PC valve, LS valve, solenoid valve and other accessories. The specific application may be different, and the actual product shall prevail for specific use. 2) Applicable models: PC200-8M0, PC200LC-8M0, PC210-8M0, PC210LC-8M0; HB205-1, HB205LC-1, HB215-1, HB215LC-1, HB205-1M0.

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.

What k3v112dt main pumps do: 1) k3v112dt main pump has high transmission efficiency to give full play to the power and fuel economy of the engine. 2) The hydraulic system and hydraulic components have sufficient reliability under the action of large load changes and sharp vibration and impact. 3) Coordinate lightweight and vibration-resistant coolers to reduce the total heat generation of the system, so that the hydraulic oil temperature does not exceed 80 degrees when the main engine continues to work, or the temperature rise does not exceed 45 degrees. 4) Due to the dust in the excavator operation site, the hydraulic oil is easily polluted. Therefore, the sealing performance of the hydraulic system is better, and the hydraulic components are less sensitive to oil pollution. The entire hydraulic system should be equipped with an oil filter and a dust-proof device. 5) Hydraulic or electro-hydraulic servo control device is adopted, so that the excavator can set up an automatic control system, thereby improving the technical performance of the excavator and reducing the labor intensity of the driver.
