Description
Technical field
The present invention relates to a kind of piston pump technology, in particular a kind of minitype piston that double cylinders are arranged along same axisymmetrical
Pump.
Background technology
For small micro-piston pump, one motor of generally use, and two cylinders are split in motor both sides, it is such as attached
Shown in Fig. 1.In this symmetrical balance-type piston pump, since two connecting rods are superimposed installation, and piston centre and company on transmission shaft
Rod axis overlaps installation, and the axis of both sides cylinder is caused unavoidably to deviate dislocation（That is decentraction）.Since connecting rod is in drive shaft
Line in-plane（As shown in Figure 1）For connecting rod with shown in piston axis such as Fig. 18,9, two connecting rods are superimposed forming position dislocation（Dislocation
Distance A）, two connecting rods misplace 180 degree in symmetrical balance-type piston pump, and piston makees constant speed counter motion, i.e., piston is reversed by two
Resultant force（The resultant force such as air resistance, frictional force）, when two cylinder bores are identical, two reversed resultant forces are equal, and axis 8,9 misplaces
Distance A is that the arm of force of reversed resultant force is poor（Difference is A）, corresponding resultant moment is constituted, and be not zero（A is not equal to 0）, formed another
A form of disturbing moment.In operation, the pump housing is by the synthesis torque for pump（Resultant moment）Reciprocating causes larger shake
Dynamic and noise.
Invention content
It is an object of the present invention to provide a kind of micro-piston pumps of double cylinder coaxial line settings.
To achieve the above object, the technical scheme is that, a kind of double cylinder coaxial lines are symmetrical arranged micro-piston pump,
Its composition includes motor, link assembly, piston, piston ring, check valve, cylinder, casing, end cap and head cover, and the motor turns
