excavator hydraulic pump price

Is the higher the filtration precision of the excavator oil filter, the better?   For an engine or equipment, an appropriate filter element should achieve a balance between filtration efficiency and ash holding capacity. Using a excavator oil filter with a high filtration precision may shorten the service life of the filter element due to the low ash capacity of the filter element, thereby increasing the risk of premature clogging of the oil filter element.

hitachi hydraulic pump parts: 1. The composition of the external feedback pressure-limiting variable vane pump: shell, bushing, stator, pump shaft, rotor, flow adjustment screw, control piston, needle roller bearing, slider, pressure limiting spring, pressure adjustment screw; 2. The hydraulic pump is a hydraulic power component in the hydraulic system. Its function is to convert the mechanical energy of the system {internal combustion engine or motor} into liquid pressure, and it is the power source of the hydraulic system. Hydraulic pump can be divided into tooth cooling pump, vane pump, plunger pump according to the structure; 3. There are many different uses of each pump. According to the different circuits, it can be divided into open pump, closed pump and so on. The core principle of hydraulic pump {Pastor's principle}: the liquid pressure is equal everywhere. That is, the pressure in the working pump cavity changes and reciprocates the oil suction and oil discharge. Kyushan got all kinds of Hitachi excavator hydraulic pumps and pump parts for sale， you can send your inquiries with the excavator model numbers you need， we will reply as soon as possible.

Precautions after replacing the new cat 320d hydraulic pump (1) 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.

The main pump type used by the caterpillar excavator hydraulic pump is: variable displacement axial piston pump Main pump maximum flow (L/min): 2×200 Walking hydraulic motor type: variable displacement axial piston motor (with mechanical brake) Rotary hydraulic motor type: axial piston motor (with mechanical brake) Variable piston pumps are divided into two types: axial variable piston pumps and radial variable piston pumps.

How to choose a good quality kobelco sk200 hydraulic pump? Of course, you must choose a reliable company to buy kobelco sk200 hydraulic pump. If you want to choose a hydraulic pump with good quality, you must choose a good company.

When the hyundai 210 excavator hydraulic pump of the excavator is seriously worn, it has a fatal impact on the excavator, so such problems in the excavator must be solved in time. When repairing the hydraulic pump of the excavator, find the cause of the failure from the following three points:

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.
