Description
Technical field
The present invention relates to a kind of liquid metering device fields, and in particular to a kind of Micro-metering Pumps pump shaft.
Background technology
Metering pump be it is a kind of can meet various stringent technological process needs, flow can be adjusted, for conveying liquid
A kind of specific pump.Because of its power drive and the difference of fluid conveying mode, metering pump is divided into plunger type metering pump, diaphragm type metering
Pump, impeller pump, peristaltic pump etc.
1. plunger type metering pump
Plunger type metering pump plunger is unidirectional in inlet and outlet directly with the media contact conveyed in linear reciprocating motion
Suction liquid is completed under the action of valve.
Plunger type metering pump feature
1) when outlet pressure changes, flow is almost unchanged；
2) energy transfer of highly viscous medium is unsuitable for conveying corrosivity slurry and dangerous chemical product.
3) leakage loss is not avoided that at packing seal.
2. diaphragm metering pump
Diaphragm metering pump reaches conveying liquid by presses against diaphragm, and diaphragm pump has hydraulic diaphragm pump, Mechanical Driven diaphragm
Pump, electromagnetic diaphragmpump etc..
Hydraulic diaphragm pump in in-oil cylinder reciprocating motion, makes intracavitary fluid generate pulsating force by plunger, pushes diaphragm
It agitates back and forth, the purpose of suction liquid is completed under the action of terminal valve.
Mechanical Driven diaphragm metering pump slide bar is directly connected to diaphragm, is directly pushed away when slide bar moves back and forth during work
(drawing) is moved diaphragm and is agitated back and forth, and suction purpose is completed by the check valve keying effect on pump head
Electromagnetic diaphragm metering pump is diaphragm to be pushed to agitate back and forth, under the action of terminal valve to drive by electromagnet
Complete the purpose of suction liquid.
Diaphragm metering pump feature
1) stationary seal, No leakage；
It 2) can transfer of highly viscous medium, abrasion slurry and dangerous chemical product；
3) diaphragm bears high stress, and membrane life is relatively low；
4) 2 megapascal of outlet pressure is hereinafter, flow smaller scope of application；Measuring accuracy is five ± percent, when pressure is from most
It is small to it is maximum when, changes in flow rate is up to 10.
3 impeller pumps
Impeller pump is to be converted to reach transport Stream by means of the periodicity of multiple fixed volumes conveying unit in working chamber
The purpose of body.
Impeller pump feature：
1) service life is long；
2) smooth running, low noise；
3) sealed reliable, since rotor revolution speed is low, sealing surface is not likely to produce high temperature, and abrasion is few.
4 peristaltic pumps
Peristaltic pump is alternately to be squeezed by the elastic delivery hose that pair of rollers pumps and discharge to pump fluid.
Peristaltic pump feature：
1) constant current, precision are high, and flow is adjusted；2) has suction capacity；3) peristaltic pump can generate pulse；
4) peristaltic pump tube is vulnerable part.
In some fine chemistry industries, food processing technology, some composition additions are seldom, but addition required precision is high.
It is small this requires measuring pump discharge, while accurate cut-off, have switching function.Control more than metering pump, pump body structure have standard
Really the metering pump of cut-off switching function only has peristaltic pump, and pump impeller rotation stops, liquid stream cut-off, but peristaltic pump tube is vulnerable part, and
Plunger type metering pump, diaphragm metering pump are to end liquid stream using check valve, and impeller pump effect of shutting off is poor.Therefore, it develops
A kind of simple in structure, good airproof performance, flow are small, have the Micro-metering Pumps of switching function, as shown in Figure 1, Figure 2, Fig. 3, Fig. 4, Fig. 5 institute
Show, be made of motor reducer, the pump housing, pump shaft, end cap, the present invention is Micro-metering Pumps pump shaft.
In view of the above problems, through patent consulting, identical Micro-metering Pumps pump shaft there is no.
Invention content
The technical problems to be solved by the invention are directed to the present situation of the prior art, provide a kind of Micro-metering Pumps pump shaft.
Technical solution is used by the present invention solves the above problems：Micro-metering Pumps pump shaft, such as Fig. 6, Fig. 7, Fig. 8, Fig. 9
It is shown, by splined shaft portion 1, the first cylinder shaft portion 2, the first cylindrical shaft and oblique slot part 3, the first cylinder ring shaft portion 4,
Quantitative slot circular shaft part 5, the second cylinder ring shaft portion 6, the second cylindrical shaft and oblique slot part 7,8 structure of the second cylinder shaft portion
Into, it is characterised in that 1 cross sectional shape of splined shaft portion is spline；First cylinder shaft portion 2,8 section shape of the second cylinder shaft portion
Shape is circle；First cylindrical shaft and oblique slot part 3, the second cylindrical shaft and 7 shape outer end of oblique slot part are cylindrical shaft, internal
For oblique slot；First cylinder ring shaft portion 4,6 shape of the second cylinder ring shaft portion are cylinder annulate shaft；Quantitative slot circular shaft part 5 is cut
Face shape is circular shaft, and circular shaft surface is evenly distributed two quantitative slots；Splined shaft portion 1, the first cylinder shaft portion 2, first circle
Axis of a cylinder and oblique slot part 3, the first cylinder ring shaft portion 4, quantitative slot circular shaft part 5, the second cylinder ring shaft portion 6, second circle
Axis of a cylinder and oblique slot part 7, the second cylinder shaft portion 8 are arranged in order from left to right.
Compared with the prior art, the invention has the advantages that pump shaft is quantified using quantitative slot, accurate measurement has simultaneously
End switching function, cylinder ring sealing, oblique slot choked flow meet requirement.
