Abstract
The invention relates to a screw type piston pump. It includes a pump body, a piston and spiral pushing bar, wedge type pushing bar, revertible spiral spring which can push the piston to take movement. The top of the spiral push bar is made to a spiral type bevel surface. A wedge, which can be set a roller on, is made on the bottom of the wedge type push bar. And two bars would match tightly by a fixation centre axis. While the wedge type push bar is axially touring, the wedge or the roller on the wedge would slide or roll on the bevel surface. The piston would be forced to move downwards by the pressure of the spiral push bar. Then, the air and the liquid would be extruded out of the pump body.
Description
Technical background
The present invention relates to the bolt type piston pump, comprising a pump housing, piston and promote each of spiral handspike, the wedge type push rod of piston motion and reply one of helical spring.
Background technique
The piston pressure pump all is to adopt power system to drive the bent axle rotation in the world, and bent axle rotation promotion connecting rod drives piston and moves up and down in the pump housing, absorbs and interior liquid or the gas of the release pump housing, reaches the purpose of lifting liquid or supercharging.
Bent axle rotate to promote connecting rod and drives piston and move up and down in the pump housing, shakes when causing piston to move up and down in the pump housing easily, increases the weight of the wearing and tearing of the piston ring and the pump housing, even causes scuffing of cylinder bore.Simultaneously, because the motion mode of bent axle motion, the vibrations of generation and dry sound are bigger.
Summary of the invention
The invention provides a kind of spiral and promote the rod-type reciprocating pump, make about the motion vertical of piston in the pump housing, avoided piston rocking in the pump housing, alleviated vibrations and dry sound simultaneously.
Bolt type piston pump of the present invention, by a pump housing, a piston and each one and one answer helical spring of spiral handspike, the wedge type push rod composition that promotes piston motion.
Spiral handspike of the present invention is to make the screw type inclined-plane on the top of push rod, and with matching is wedge shaped ejector pin, and a wedge is given prominence in the lower end of wedge shaped ejector pin, on the wedge roller bearing once can be installed, be used to the power of reducing friction, spiral handspike and wedge type push rod pass through fixedly axis, and two bars are closely cooperated.The spiral handspike hypomere is partly made non-cylinder, be stuck in the pump housing every in, like this, wedge shaped ejector pin can only axial rotation, the screw push rod can only move up and down, and can not do axial motion.
The object of the present invention is achieved like this: power system drives wedge shaped ejector pin and makes axial rotation, roller bearing on wedge or the wedge just slides on the screw inclined plane of screw push rod or rolls, owing to be on screw inclined plane, to move, cause spiral handspike to be under pressure, generation moves downward, and drives piston and moves downward, and closes pump housing inlet, open pump housing outlet, squeeze out the gas or the liquid of the pump housing.After wedge or roller bearing moved to the top of screw inclined plane, motion just lost the pressure to screw inclined plane again, replied helical spring and made on the spiral handspike and move, and promoted to move on the piston, sucked gas or liquid.So move in circles, the rotation that the wedge type push rod does not stop, the rotation that wedge on it or roller bearing do not stop, under its pressure effect and under the helical spring effect of answer, what spiral handspike did not stop moves up and down, and drives piston and squeezes out and suck gas or liquid.
The invention described above bolt type piston pump can overcome the rock problem of piston in the pump housing of curved shaft type reciprocating pump, the wearing and tearing that alleviate the piston ring and the pump housing, and no bent axle athletic meeting alleviates the vibrations of pump, and can reach the purpose that promotes liquid or supercharging.Spiral piston pump structure is simple.

Embodiment
As shown in Figure 1, bolt type piston pump of the present invention is made up of the pump housing 1, a piston 2 and the spiral handspike 3 and the returning spring 4 that promote piston 2 motions.Power system drives wedge type push rod 5 and does axial motion, wedge on it or roller bearing 6 move on the screw inclined plane on the spiral handspike 37, because screw inclined plane 7 is inclined-planes, wedge or roller bearing 6 move on screw inclined plane 7, can promote spiral handspike 3, and generation moves downward, spiral handspike 3 promotes piston 2 and moves downward, close the inlet valve 8 of the pump housing 1, open the outlet valve 9 of the pump housing 1, squeeze out gas or liquid in the pump housing.After wedge type push rod 5 was rotated further, and wedge or roller bearing 6 rise to the top of screw inclined plane 7, motion promptly lost the pressure to screw inclined plane 7 again, and returning spring 4 is about to spiral handspike 3 tops and comes up, wedge or roller bearing 6 beginnings motion on the plane 10 of spiral handspike 3.Under the promotion of returning spring 4, spiral handspike 3 drives piston 2 and moves upward, and closes the outlet valve 9 of the pump housing 1, opens the inlet valve 8 of the pump housing 1, and gas or liquid are sucked in the pump housing 1.So move in circles, reach the purpose that promotes liquid or supercharging.
By Fig. 2, Fig. 3 as can be known, there are screw inclined plane 7 and plane 10 in the upper end of spiral handspike 3, and spiral handspike installs and fixes the push rod mesopore 12 of axis 11 in addition, and fixedly axis 11 can slide up and down in push rod mesopore 12.
Outstanding wedge is arranged the lower end of wedge type push rod 3 as can be known by Fig. 1, Fig. 4, Fig. 5, Fig. 6, on the wedge roller bearing 3 can be installed, roller bearing 3 links to each other with wedge with fixing axis 11 by roller bearing axis 13.Fixedly axis 11 is fixed on the wedge type push rod 5 by fixing pin 14.
The hypomere 15 of the spiral handspike 3 among Fig. 1 is made non-cylinder, is stuck in the pump housing in 16, and it can only be moved up and down, and can not do axial motion.
