Description

A kind of parallel pump housing of plunger
Technical field
The utility model belongs to pump configuration, and in particular to a kind of parallel pump housing of plunger is used for high-pressure cleaning device.
Background technique
Handheld high-voltage cleaning machine is formed the pressure difference variation of internal water cavity, is generated water suction and gone out by the reciprocating motion of plunger The effect of water.In the comparable situation of power mechanism parameter, the volume of plunger, the volume differences of plunger and cavity, the volume of cavity It is to codetermine water yield.The pump unit as disclosed in CN107061213A and Handheld high-voltage cleaning machine, CN207025945U are public The Handheld high-voltage cleaning machine opened improves water yield by increasing the quantity of plunger.However, being used in actual operation, with plunger The increase of quantity, the load of power mechanism are also improving, and resistance suffered by the operation of power output shaft and transmission shaft also exists Increase, card resistance phenomenon easily occurs, body operation is unsmooth, out the problems such as water unstable;Although can be by with the dynamic of high load Force mechanisms solve, but the volume of high load power mechanism is big, weight is big, can not be with the small-scale structure of Handheld high-voltage cleaning machine Match.
Summary of the invention
It is in parallel to have invented a kind of plunger for the above problem existing for plunger pump of the utility model mainly for jetting machine The formula pump housing is additionally arranged split type plunger monomer on the basis of original integrated pole plug structure, plunger monomer and transmission shaft or Person's bearing is only contacted and is not connected to, and under the action of elastic recovery part, plunger monomer and transmission shaft or bearing, which are formed, contradicts connection; On the one hand the reciprocating motion of plunger monomer is the impetus of transmission shaft, be on the other hand that the two-way rebound of elastic recovery part is made With greatly alleviating the load of transmission shaft, even if multiple groups plunger is arranged simultaneously, body can still be operated normally.
The above-mentioned technical problem of the utility model is carried out by the following technical programs: a kind of parallel pump of plunger Body, including being internally provided with the cylinder body of chamber, being arranged in the indoor plunger mechanism of chamber, transmit kinetic energy and plunger mechanism is driven to carry out The eccentric gearing shaft assembly of straight reciprocating motion, the straight reciprocating motion direction of plunger mechanism is perpendicular to eccentric gearing shaft assembly Axis direction, which is characterized in that the plunger mechanism includes integrated plunger and seperated plunger.
