Problems solved by technology

[0003] However, in some occasions, it is not possible to provide power on site. First, it is restricted by safety protection and is not allowed to use electricity on site, such as explosive dust and gas environments; Power supply is provided at a considerable distance. At this time, the hydraulic system needs to set the actuator at the construction site, and set the hydraulic pump at a place far away from the construction site to connect the power supply, which requires a long hydraulic pipeline. The problem is: 1. The longer the hydraulic pipeline, the greater the pressure loss, which cannot meet the load requirements of the actuator; road damage

Abstract

The invention discloses a pneumatic oil pump which comprises an oil inlet, an oil compressing port and an oil pipe connecting with the oil inlet and the oil compressing port. A driving mechanism of the oil pump is a pneumatic device, i.e. the oil pipe between the oil inlet and the oil compressing port is divided into two hydraulic pipes which are communicated with each other end to end, and each hydraulic pipe is provided with two same check valves. The conducting direction of the check valves is from the oil inlet to the oil compressing port; a tee coupling is arranged between the two check valves on each hydraulic pipe; and the two tee couplings on the two pipes are connected with oil cavities at two ends of a pneumatic reciprocation cylinder. Adopting the technical scheme, the pneumatic oil pump utilizes pneumatic pressure to obtain continuous high-pressure hydraulic oil, can conveniently adjust the pressure to realize automatic pressure control of a system, does not need a power supply, realizes safe application, meets requirements of different construction places, is widely superior to various hydraulic transmission systems, and has compact structure and convenient use.

Description

technical field [0001] The invention belongs to the technical field of pneumatic and hydraulic transmission, and relates to a power device of a hydraulic system. More specifically, the invention relates to a pneumatic oil pump. Background technique [0002] In a hydraulic transmission system, a hydraulic pump needs to be installed, and the hydraulic pump should be as close as possible to the hydraulic actuator. The driving device of the hydraulic pump is an electric motor, which needs to be supplied with power. [0003] However, in some occasions, it is not possible to provide power on site. First, it is restricted by safety protection, and it is not allowed to use electricity on site, such as explosive dust and gas environments; The power supply is provided at a considerable distance. At this time, the hydraulic system needs to set the actuator at the construction site, and set the hydraulic pump at a place far away from the construction site to connect the power supply, w...
