Hydraulic slurry pump

Abstract

The invention discloses a hydraulic slurry pump. The hydraulic slurry pump comprises a hydraulic cylinder body, a slurry pump body, a piston rod, and a connecting block which is arranged between the hydraulic cylinder body and the slurry pump body and used for connecting the hydraulic cylinder body and the slurry pump body. The piston rod is connected in the connecting block in a sliding mode, theleft end of the piston rod is located in the hydraulic cylinder body, and the right end of the piston rod is located in the slurry pump body. A hydraulic piston connected with the left end of the piston rod is connected in the hydraulic cylinder body in a sliding mode, and a slurry piston connected with the right end of the piston rod is connected in the slurry pump body in a sliding mode. A hydraulic end cover is installed at the left end of the hydraulic cylinder body and provided with a reversing valve for controlling the reciprocating motion of the hydraulic piston. A slurry end cover isinstalled at the right end of the slurry pump body and provided with a one-way valve assembly for controlling slurry to get into and out of the slurry pump body. The slurry pump is not only simple instructure but also free of electric control.

Description

technical field [0001] The invention relates to the technical field of mud pumps, in particular to a hydraulic mud pump. Background technique [0002] With the large-scale application of large-scale mechanical equipment, hydraulic drive has been widely used as a very important driving method, and the hydraulic system and its related technologies are becoming more and more mature. Especially in the field of mud pump application technology, the traditional mud pump uses a crank-connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder to pump the mud out. In addition, in the current hydraulic mud pump, the reversing valve that realizes the reciprocating movement of the piston mostly uses an electromagnetic reversing valve and a displacement sensor to control the reversing, and the sensor is controlled by a proximity switch, and the reversing is unstable. Unreliable, complex structure, and inconvenient replacement; the control circuit part of...

Problems solved by technology

Especially in the field of mud pump application technology, the traditional mud pump uses a crank connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder to pump the mud out. In addition, in the current hydraulic mud pump, the reversing valve that realizes the reciprocating movement of the piston mostly uses an electromagnetic reversing valve and a displacement sensor to control the reversing. The sensor is controlled by a proximity switch, and the reversing is unstable. Unreliable, complex structure, and inconvenient replacement; the control circuit part of the reversing device is controlled by a circuit board, because the circuit board is a non-standard part, and it is difficult to manufacture and process, and it is very difficult to repair after damage. It is inconvenient to find the reason, which greatly reduces the production efficiency; if the existing reversing device is continuously powered on for a long time, it is easy to damage small devices, which can meet the requirements of long-term power supply, and also affects the production efficiency to a certain extent
