Double Cylinder Single Feed Hydraulic Piston Pump

Abstract

The invention discloses a double-cylinder single-feeding hydraulic piston pump. The piston pump comprises a double-bar double-acting hydraulic oil cylinder and two sludge cylinders, wherein the two sludge cylinders are arranged at the two ends of the double-bar double-acting hydraulic oil cylinder correspondingly, the double-bar double-acting hydraulic oil cylinder is provided with a double-bar double-acting hydraulic oil cylinder piston rod, the two sludge cylinders are both provided with sludge cylinder pistons, the sludge cylinder pistons of the two sludge cylinders are arranged at the twoends of the double-bar double-acting hydraulic oil cylinder piston rod correspondingly, one ends of the sludge cylinders are provided with three-way type low-damping double-acting one-way valves, andthe other ends of the sludge cylinders are provided with sludge cylinder connecting end covers. According to the piston pump, the double-bar double-acting hydraulic oil cylinder piston rod moves backand forth to push the sludge cylinder pistons, at the two ends, of the two sludge cylinders to move back and forth, upper discharging opening one-way valves and lower feeding opening one-way valves ofthe three-way type low-damping double-acting one-way valves of the sludge cylinders are alternately opened and closed so that feeding and discharging can be completed, and material pumping is achieved through the reciprocating motion.

Description

technical field [0001] The invention relates to the field of sludge pumps, in particular to an energy-saving and environment-friendly dual-cylinder single-feed hydraulic piston pump. Background technique [0002] Hydraulic piston sludge pump sewage pump is a tool that uses strong pressure to realize mud or sewage transmission. It is an indispensable equipment for engineering production and environmental protection equipment. Hydraulic piston sludge pump sewage pumps currently on the market use hydraulic cylinders as power The cylinder drives the piston movement of the working cylinder, and the inlet and outlet adopt a three-way joint. Two check valves are respectively installed as the inlet one-way check and the outlet one-way check. This structure will inevitably cause the material to pass through during the feeding and discharging process The tee, some elbows and the transmission pipeline are too long, resulting in increased resistance, which affects the operating efficien...

[0002] Hydraulic piston sludge pump sewage pump is a tool that uses strong pressure to realize mud or sewage transmission. It is an indispensable equipment for engineering production and environmental protection equipment. Hydraulic piston sludge pump sewage pumps currently on the market use hydraulic cylinders as power The cylinder drives the piston of the working cylinder, and the inlet and outlet adopt a three-way joint. Two check valves are respectively installed as the inlet one-way check and the outlet one-way check. This structure will inevitably cause the material to pass through during the feeding and discharging process The tee, some elbows and the transmission pipeline are too long, resulting in increased resistance, which affects the operating efficiency and manufacturing cost of the whole machine, and the size of the whole machine is too large to waste resources and on-site installation space; the imported and exported one-way valve is Angle-through type, that is, the inlet and outlet of the check valve are at 90 degrees, and the material is prone to turbulence during the transmission process; there is no cooling system in the cylinder of the working cylinder, and the heat generated during the operation of the equipment cannot be conducted and dissipated in time, resulting in the aging of the piston seal of the working cylinder Failure; the hydraulic cylinder is used as a power cylinder, because the installation position of the reversing device is fixed when the hydraulic cylinder is reversing, the motion inertia and the hysteresis of the reversing valve are extremely easy to cause the piston and the two ends of the cover to collide and cause the cylinder to hit the cylinder
