Abstract

The invention belongs to the field of engineering equipment, and specifically relates to a plunger pump and a combined pump. The plunger pump comprises a cylinder body and a plunger carrying out reciprocating movement in the cylinder body, wherein a plunger rod of the plunger carrying out the reciprocating movement is one of the components of a lead screw pair, and the plunger rod is capable of receiving a torque and carrying out the reciprocating movement in the cylinder body; the plunger rod is a nut of the lead screw pair; a key slot is formed in the nut; a guide key is arranged in the keyslot; a guide sleeve is arranged on the nut; a guide key slot is formed in the guide sleeve; the guide key slides in the guide key slot; the plunger and a bolt I are arranged at the upper end of the nut; a key and a press plate II are arranged on a screw rod of the lead screw pair; a gear and a bolt II are arranged on the screw rod; the guide sleeve is fixed to the inner wall of the cylinder bodythrough a location pin; a plunger hole is formed in the top of the cylinder body; and the plunger and the cylinder body form fit through the lead screw pair, and realize suction-in and pumping-out formortar or concrete. The plunger pump and the combined pump are simple in structure; and compared with an existing rotor with a cam structure, of a wet spraying machine, the plunger pump and the combined pump are low in cost and convenient to repair.

Description

technical field [0001] The invention belongs to the field of engineering equipment, in particular to a plunger pump and a combined pump. Background technique [0002] The rotor of the wet spraying machine using the cam structure in the existing pulse-free spraying and grouting technology has high cost, and the plunger rod is prone to bending, which makes the rotor unable to work and affects the construction progress. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above technical difficulties and provide a plunger pump with simple structure and convenient maintenance and operation. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A plunger pump, comprising a cylinder body and a reciprocating plunger in the cylinder, the plunger rod of the reciprocating plunger is one of the components of a screw pair, so that the plunger rod can reciprocate in the cylinder . ...
