Embodiment 2

[0012] Embodiment 2. A lead screw piston pump is composed of two single-cylinder lead screw piston pumps as described in embodiment 1 and combined to form a double-cylinder lead screw piston pump.

[0013] In the working state, when the piston is at the bottom of the cylinder, the lead screw pulls the piston upwards through the screw nut, and when it touches the upper limit switch, the screw nut moves down through the main shaft commutator and reciprocates.

Abstract

The invention belongs to pumps, more precisely, it is a lead screw piston pump. Lead screw piston pump consists of motor, main shaft commutator, lead screw, screw nut guide rod, connecting support rod, screw nut, piston rod, discharge valve, piston, cylinder block, outlet flange, inlet flange, suction valve, The upper support, the lower support, the lower limit switch and the upper limit switch are composed, wherein the piston and the piston rod are connected with the screw nut as a whole, and the screw nut is engaged with the lead screw. The invention adopts the connection of the piston, the piston rod and the screw nut, and the meshing movement of the screw nut and the lead screw is the power of the pump body, the discharge pressure is strong, the structural moving parts are few, the cost is low, and the power is strong, especially suitable for viscous media and long-distance Transmission, with the characteristics of energy saving and high efficiency.

Description

technical field [0001] The invention belongs to pumps, more precisely, it is a lead screw piston pump. Background technique [0002] At present, the general types of pumps include centrifugal type, diaphragm type, crankshaft piston type, etc. Pumps with various structures are suitable for the transmission of liquid and gaseous media. The transmission capacity of the pump depends on the power of the pump. The capacity of the power source of the traditional structure pump is relatively low, and the transmission capacity of large-capacity, long-distance, and high-viscosity media is poor. Contents of the invention [0003] In view of this, the object of the present invention is to provide a lead screw piston pump with higher power. [0004] The purpose of the present invention is achieved through the following technical measures: a lead screw piston pump, consisting of a motor, a main shaft commutator, a lead screw, a screw nut guide rod, a connecting support rod, a screw nut...
