mini excavator hydraulic pump

Caterpillar excavator filter maintenance 1. The caterpillar oil filters is the core component of the filter. It is made of special materials and is a wearing part, which requires special maintenance and maintenance; 2. When the caterpillar oil filters has been working for a long time, the filter element has intercepted certain impurities, which will lead to an increase in pressure and a decrease in flow. At this time, it needs to be cleaned in time;

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.

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.

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:

Hitachi ex60 hydraulic pump maintenance instructions 1. When the excavator is working and the pump abnormal sound, the excavator vibrates, or the computer board displays a fault code or an alarm, be sure to stop the machine to check whether it is caused by the hitachi ex60 hydraulic pump failure. 2. When the operating environment temperature of the excavator is very low, it is necessary to run the excavator idling for more than 10 minutes after the excavator is started. After the temperature of the excavator rises, load the excavator to ensure that the hydraulic pump of the excavator works normally. 3. The excavator must always pay attention to whether the hydraulic oil temperature of the excavator is too high? Is the water temperature of the excavator too high? ex60 hydraulic parts: hydraulic pump and accessories, pump cylinder plane, plunger, cylinder block, return plate, nine-hole plate, transmission shaft, pilot pump, thrust plate, swing seat (swing assembly), ball dumpling, friction plate, Separator, oil distribution pan, hydraulic plunger pump accessories, lifter, ball joint and other hydraulic pump accessories.

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.
