Description
Technical Field
The utility model relates to a plunger pump, concretely relates to plunger pump of zero leakage.
Background
The plunger pump is a hydraulic pump which uses 1 crankshaft to directly push a plunger to do reciprocating motion through a connecting rod slide block or an eccentric shaft to realize liquid suction and discharge, mostly adopts a valve type flow distribution device, and is mostly a constant displacement pump. The working principle is that the rotation of the crankshaft drives the piston to do reciprocating motion, so as to realize liquid suction and liquid discharge. The plunger pump is a common conveying device in chemical machinery, and is mostly used for conveying media such as various additives. Because the plunger and the transmission part of the existing plunger pump are contacted with the conveying medium in the conveying process, after the existing plunger pump is used for a period of time, the problem of leakage of the conveying medium exists due to various reasons, such as poor sealing caused by the loss of activity of the packing seal of the transmission part, and the like.
Disclosure of Invention
The utility model aims at providing a zero plunger pump that leaks.
In order to solve the problem existing in the background art, the utility model discloses a technical scheme be: the utility model provides a zero leaks plunger pump, includes crank, connecting rod, plunger pump body and plunger, its characterized in that: the plunger pump body is divided into an inner ring and an outer ring by a non-magnetic isolating ring, the plunger consists of a magnetic piston and a permanent magnet, and the permanent magnet is fixed on the connecting rod and is positioned at the inner ring of the plunger pump body; the magnetic piston is positioned on the outer ring of the plunger pump body and forms magnetic coupling drive with the permanent magnet, a piston ring is arranged between the outer end of the magnetic piston and the inner wall of the plunger pump body, and the piston ring is fixed on the magnetic piston through a piston ring positioning sleeve; the outer ring of the plunger pump body is provided with an oil inlet pipe and an oil outlet pipe on two sides of the plunger.
The connecting rod and the sealing of the plunger pump body adopt a three-petal sealing ring.
And a blank cap is arranged outside the linear bearing at the right end of the connecting rod.
The utility model discloses a change the structure of the plunger pump body and plunger, will carry the transmission position branch of medium and plunger pump to separate with the non-magnetic separation ring, isolated the contact of carrying the medium to the transmission position to realize carrying medium zero leakage in transportation process.

Detailed Description
The invention is further described below with reference to the drawings and the specific examples.
From fig. 1, the utility model relates to a zero-leakage plunger pump, including crank 3, connecting rod 2, plunger pump body 1 and plunger, plunger pump body 1 is divided into inner circle and outer lane by non-magnetism isolating ring 14, and non-magnetism isolating ring is the drum that non-magnetism material made, the plunger comprises magnetic piston 4 and permanent magnet 5, and permanent magnet 5 is fixed on connecting rod 2, and is located the inner circle of plunger pump body 1; the magnetic piston 4 is positioned on the outer ring of the plunger pump body and forms magnetic coupling drive with the permanent magnet 5, a piston ring 7 is arranged between the outer end of the magnetic piston and the inner wall of the plunger pump body 1, and the piston ring 7 is fixed on the magnetic piston 4 through a piston ring positioning sleeve 6; the outer ring of the plunger pump body is provided with an oil inlet pipe and an oil outlet pipe on two sides of the plunger, and the oil inlet pipe and the oil outlet pipe are provided with check valves.
The connecting rod 2 and the plunger pump body 1 of the utility model are sealed by a three-petal sealing circle 13; a blank cap is arranged outside a linear bearing at the right end of the connecting rod and used for preventing air disturbance caused by movement of the connecting rod.
The utility model discloses a working method:
when the crank 3 moves to drive the connecting rod 2 to move leftwards, the permanent magnet 5 on the connecting rod also moves leftwards, the permanent magnet 5 drives the magnetic piston 4 to move leftwards in a magnetic coupling mode, due to the action of the one-way valve, the cavity on the right side of the pump body of the plunger pump is used for vacuum oil absorption, conveying media enter the cavity on the right side of the pump body of the plunger pump from the right oil inlet pipe, meanwhile conveying media in the cavity on the left side of the pump body of the plunger pump gradually flow out from the left oil outlet pipe under the action of the magnetic piston 4, finally the cavity on the right side of the pump body of the plunger pump; when the crank 3 moves to drive the connecting rod 2 to move rightwards, the permanent magnet 5 on the connecting rod also moves rightwards, the permanent magnet 5 drives the magnetic piston 4 to move rightwards in a magnetic coupling mode, due to the action of the one-way valve, the cavity on the left side of the plunger pump body is used for vacuum oil absorption, conveying media enter the cavity on the left side of the plunger pump body from the left oil inlet pipe, meanwhile conveying media in the cavity on the right side of the plunger pump body gradually flow out from the right oil outlet pipe under the action of the magnetic piston 4, finally the cavity on the left side of the plunger pump body is filled with the conveying media, and the conveying media in; the above process is repeated.
The utility model discloses owing to set up the non-magnetism nature cage washer between connecting rod and permanent magnet and magnetic piston, the transmission position that non-magnetism nature cage washer will carry medium and plunger pump is separated, like this in whole transportation process, carries the medium and only flows in the outer lane of the plunger pump body, and the utility model discloses a transmission part is located the inner circle of the plunger pump body to realize carrying medium zero leakage in transportation process.
The embodiment of the utility model only is the description of going on the implementation way, and not right the utility model discloses the design and the scope are injectd, do not deviate from the utility model discloses under the prerequisite of design idea, engineering technical staff is right in the field the various variants and the improvement that technical scheme made all should fall into the utility model discloses a protection scope.
