Novel buffering oil cylinder for hydraulic pump station

The invention relates to a novel buffering oil cylinder for a hydraulic pump station. The novel buffering oil cylinder for the hydraulic pump station is characterized in that two oil lines are respectively arranged on two sides of the oil cylinder, namely an oil inlet line which is placed in a non-rod cavity and an oil line which is placed in the rod cavity; the two oil lines are respectively composed of two pairs of branch lines, namely and respectively, a first inner branch line and a first outer branch line, a second inner branch line and a second outer branch line, wherein inner oil inlets of the first inner branch line and the second inner branch line are respectively formed in two sides on the inner wall surface of the cylinder above a piston, and the inner oil inlets of the first outer branch line and the second outer branch line are respectively formed in the cylinder cover at left and right ends of the piston. According to the novel buffering oil cylinder for the hydraulic pump station, the buffering distance can reach below 10mm, the piston is adopted to replace a traditional cylindrical cone body to cover the oil port, one oil port is designed to be arranged on the inner wall of the cylinder, and the piston is utilized to close the oil port. Due to the facts that the cylinder and the piston are a pair of parts matched accurately, and the distance between the cylinder and the piston is small, oil lines can be shut down instantly, processing is easy, and therefore buffering stroke is small, and buffering effect is good.
