k3v112dt main pump

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.
