Abstract

The invention discloses a multistage plunger hydraulic sludge pump and belongs to the technical field of sludge pumps. The multistage plunger hydraulic sludge pump comprises working cylinders and a power cylinder, wherein each working cylinder is composed of a cylinder body and a plunger, the power cylinder is composed of a cylinder body and a plunger, the working cylinders and the power cylinder are axially connected into a whole through connecting components, plunger rods of the plungers of all the working cylinders and the plunger rod of the plunger of the power cylinder are connected to form a straight rod, each working cylinder is provided with two sludge feed inlets provided with one-way valves and two sludge discharge outlets provided with one-way valves, the power cylinder is provided with a hydraulic oil inlet and a hydraulic oil outlet, the plunger of the power cylinder is pushed to make reciprocating motion through feeding and discharging of hydraulic oil, and the plungers in the working cylinders are driven to make reciprocating motion at the same time. By means of a multistage cylinder formed by connection of multiple single-stage working cylinders, the continuous process that discharging and feeding are conducted through multiple discharge outlets and multiple feed inlets at the same time is achieved, high flow can be realized with a small pipe diameter, feeding time is shortened, and feeding efficiency and discharging efficiency are improved.

Description

technical field [0001] The invention relates to the field of an energy-saving sludge pump, in particular to a low-pressure, high-flow multistage plunger hydraulic sludge pump suitable for sludge treatment construction. Background technique [0002] At present, in the process of sludge treatment, the feed pumps of the sludge dewatering machine include: plunger pumps, diaphragm pumps, screw pumps, vane pumps, gear pumps, etc.; screw pumps are small in size, simple in structure, and can pump high viscosity. The medium with poor fluidity has no shear, no agitation, no turbulent pulsation, and smooth pumping. It is widely used in the feed pump of the sludge dewatering machine; but its wear resistance is poor, the pressure loss is large, and the maintenance frequency is high. , Especially in high-pressure operation, the stator is easy to wear and lose pressure, and the flow rate is small, the power is large, and the energy consumption is high, so the operating cost of the screw pu...
