Double cylinder and double feed hydraulic piston pump

Abstract

The invention relates to a double cylinder and double feed hydraulic piston pump which comprises a double rod delivering double-acting hydraulic oil cylinder and two sludge cylinders, wherein the twosludge cylinders are separately mounted at two ends of the double rod delivering double-acting hydraulic oil cylinder; the double rod delivering double-acting hydraulic oil cylinder is provided with apiston rod of the double rod delivering double-acting hydraulic oil cylinder; the two sludge cylinders are provided with pistons of the sludge cylinders; the pistons of the sludge cylinders of the two sludge cylinders are separately mounted at two ends of the piston rod of the double rod delivering double-acting hydraulic oil cylinder, wherein the piston rod of the double rod delivering double-acting hydraulic oil cylinder moves back and forth to drive the pistons of the sludge cylinders of the two sludge cylinders at tow ends to move back and forth to be opened and closed by an upper discharge opening one-way valve and a lower feeding port one-way valve arranged at two ends of the two sludge cylinders alternately to finish feeding and discharging, so that materials are pumped by 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 double-cylinder double-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 effici...

[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
