Description

Multi-cylinder plunger pump with manual rocker

Technical Field

The utility model belongs to the technical field of water treatment equipment; in particular to a multi-cylinder plunger pump with a manual rocker.

Background

According to the working principle, the pump can be divided into an impeller pump, an injection pump and a positive displacement pump. The impeller pump drives liquid to rotate at high speed by an impeller so as to transfer mechanical energy to the conveyed liquid. The impeller type can be divided into the following according to different impeller and flow passage structure characteristics of the pump: centrifugal pumps, axial flow pumps, mixed flow pumps and vortex pumps. The jet pump uses high-speed jet flow generated by working fluid to eject fluid, and then increases the energy of the ejected fluid through momentum exchange. The positive displacement pump sucks and discharges liquid by periodically increasing and decreasing working volume caused by the movement of a working part, and directly increases the pressure energy of the liquid by the extrusion of the working part, and the positive displacement pump is divided into the following steps according to the different movement modes of the moving part: reciprocating pumps and rotary pumps; the structure of the moving part is divided into: piston pump, plunger pump, gear pump, screw pump, vane pump and water ring pump. For example, chinese patent document CN103982390B discloses an end cam type single-cylinder micro-flow plunger pump directly driven by a servo motor, which is invented by professor zhao tonton, and the main structure of the end cam type single-cylinder micro-flow plunger pump adopts a ball designed in the middle of an end cam to achieve the purpose of a small-flow pump.

The pumps are electrically driven to realize the functions of the pumps, but the pumps cannot be used in outdoor activities, so that a manual plunger pump with high flow and reliable structure needs to be designed according to the conditions.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the utility model discloses but manual rocker multi-cylinder plunger pump is taken and disclosed, the technical scheme of adoption is: the utility model provides a but multi-cylinder plunger pump of manual rocker, includes that rocker, left cam, right cam, plunger jar, a plurality of both ends are equipped with the plunger, water inlet and the delivery port of gyro wheel, the rocker passes through the key and connects left cam and right cam respectively, the terminal surface contour line of left cam and right cam is the same, all designs for sinusoidal to left cam and right cam are installed according to the mode of crest to trough, trough to crest, a plurality of both ends are equipped with the plunger of gyro wheel and are installed between crest and the trough of left cam and right cam, the plunger jar suit is outside the plunger of gyro wheel is equipped with at a plurality of both ends, water inlet and delivery port in plunger jar same one side.

Preferably, the utility model relates to a but manual rocker multi-cylinder plunger pump, the plunger quantity that the gyro wheel was equipped with at both ends is the even number.

Preferably, the utility model relates to a but manual rocker multi-cylinder plunger pump, left cam and right cam terminal surface contour line are n times sine, cosine curve.

Preferably, the utility model relates to a but manual rocker multi-cylinder plunger pump, the rocker is manual gear rocker.

The working principle and the technical effect are as follows:

the utility model discloses the power supply can be artifical manual rocking rod, and what adopt is special mechanical structure, left and right cam structure promptly, and left and right cam terminal surface contour line designs for sinusoidal, and this can realize the continuous change of cam acceleration curve, and the gyro wheel of plunger can not take place the sudden change when last lower dead center and assault promptly. Specifically, the working surfaces of the left and right cams are a pair of continuous mutually cooperating peaks and valleys, and the middle of the left and right cams is a sealing plunger for a plurality of pairs of sliding rollers, i.e. adjacent rollers are arranged to differ by one-half of a period each. Along with the rocker rotates, when the left cam gradually moves to the wave trough from the wave crest, the right cam correspondingly moves to the wave crest from the wave trough, thereby driving a plurality of pairs of linear reciprocating motions of plungers with rollers at two ends, and finishing the functions of water absorption and drainage of the hand-operated plunger pump. According to the characteristics of the cam, the circular rotation of the cam is converted into the reciprocating linear motion of the plunger.

The pump adopting the structure has the greatest advantages that the plunger with the rollers at two ends is always kept between the left cam and the right cam, so that the load born by the plunger is not alternating side pressure but only pushing pressure, and the service life of the plunger is greatly prolonged; because even number of plungers are uniformly arranged on the circumference, the power output stability is good; because of adopting the design of horizontal opposition, so the whole dynamic stress is balanced, the mechanical structure performance is reliable, and the service life of the pump is long; the hand power source is selected, the rocker multi-cylinder plunger pump can be used in outdoor limit environment, and is particularly suitable for outdoor activities.
