Piston Link Mechanism

Abstract

The invention provides a piston linkage mechanism, which comprises a sludge cylinder piston, a double-acting hydraulic oil cylinder piston rod, a sludge cylinder key and a sludge cylinder key self-locking nut, the sludge cylinder piston and the double The piston rod of the hydraulic oil cylinder is fixed axially and radially by the sludge cylinder key, and the sludge cylinder key is axially locked and sealed by the self-sealing nut.

Description

technical field [0001] The invention relates to the field of link mechanisms, in particular to a piston link mechanism applied to a sludge 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 efficiency and manufacturing cost of the whole...

[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
