Abstract

The invention belongs to the technical field of hydraulic plunger pumps and motors, in particular to a lubricating, cooling and filtering integrated device for hydraulic pumps and motors. It specifically includes manifold, cooler, coarse filter, fine filter, gear pump, one-way valve, relief valve; said manifold is set on hydraulic pump or motor, said coarse filter and said fine filter The gear pump is arranged on the integrated block and connected with the main shaft of the hydraulic pump or motor through a key. The cooler is arranged outside the integrated block and connected to the integrated block through pipelines. The internal oil circuit of the block is connected, and the one-way valve and the overflow valve are arranged on the integrated block. The invention takes hydraulic pumps or motors as the application background, realizes high integration of cooling, lubrication and filtration through the integrated block, reduces the pollution of the external environment, effectively improves the service life of the cooling and filtering device, and is convenient to install and disassemble.

Description

technical field [0001] The invention belongs to the technical field of hydraulic plunger pumps and motors, in particular to a lubricating, cooling and filtering integrated device for hydraulic pumps and motors. Background technique [0002] Most of the existing domestic hydraulic plunger pumps or motors are lubricated with oil. The impurities in the hydraulic oil and the temperature rise will accelerate the wear of key friction pairs. Most of the existing hydraulic plunger pumps or motors use the oil tank shell to dissipate heat. Or externally connected cooling filter pipeline to reduce the pollution of hydraulic oil. With the development of hydraulic systems towards high pressure and large flow, hydraulic plunger pumps or motors have higher requirements on the temperature and filtration accuracy of hydraulic oil. The existing cooling and filtering circuit takes up a lot of space, and most of the hydraulic components are directly in contact with the outside air, the compone...
