Problems solved by technology

In this way, more valves need to be used in the entire cylinder system, which increases the hydraulic loss and increases the production cost, and the hydraulic oil flows back and forth in the cylinder and the oil tank, which easily leads to the contamination of the hydraulic oil

Abstract

The invention discloses an efficient energy-saving oil cylinder and engineering equipment, and relates to the technical field of hydraulic pressure. The efficient energy-saving oil cylinder comprises a telescopic cylinder, a cylinder body, a fixing rod, a connecting pipe, a first piston sleeve, a second piston sleeve and a third piston sleeve. The first piston sleeve is fixedly connected to the inner side of the cylinder body, the second piston sleeve is fixedly connected to the outer side of the telescopic cylinder, and the cylinder body, the first piston sleeve, the telescopic cylinder and the second piston sleeve jointly define an annular cavity; the third piston sleeve is fixedly connected to the fixing rod, and the telescopic cylinder, the fixing rod and the third piston sleeve jointly define an oil passing cavity. A hydraulic oil channel is arranged in the fixing rod, one end of the hydraulic oil channel is communicated with the oil passing cavity, and the other end is communicated with the annular cavity through a connecting pipe. According to the efficient and energy-saving oil cylinder, use of valves can be reduced, hydraulic loss and production cost are reduced, high efficiency and energy conservation are achieved, use of an oil tank is omitted, and pollution to hydraulic oil can be reduced as much as possible.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a high-efficiency and energy-saving oil cylinder and engineering equipment. Background technique [0002] At present, in the application of the oil cylinder, the oil cylinder is generally connected with the oil tank. When the hydraulic pump pumps the hydraulic oil in the oil tank into the rodless chamber of the oil cylinder, the piston rod of the oil cylinder stretches out. At this time, the rod chamber of the oil cylinder The hydraulic oil in the oil tank returns to the oil tank. When the hydraulic pump pumps the hydraulic oil in the oil tank into the rod chamber of the cylinder, the piston rod of the oil cylinder retracts. At this time, the hydraulic oil in the rodless chamber of the oil cylinder returns to the oil tank. In this way, more valve parts are needed in the entire oil cylinder system, which increases the hydraulic loss and increases the production cost, and the hy...
