Description
Technical field
The present invention relates to a kind of eccentric adjustable plunger pump.
Background technique
Plunger pump is widely used at food, medicine and the field such as biochemical, predominant use is quantitative filling and carries liquid, existing filling liquid and transfer pump are mostly roller type, adopt electronic circuit to control constant-delivery pump automatic transport, the general rotating speed that adopts electronic circuit control mechanism center rest, roller rolls Elastic plastic-rubber pipe, just can realize the liquid conveying that flow velocity in pipe equals rolling speed, this mode of movement is reliable and stable, but the fatigue damage that also exists plastic pipe repeatedly to roll.
Meanwhile, this conveying is to carry out adjust flux by speed governing, and the amount that is relatively applicable to conveying material is generally very little, is also inconvenient to regulate the liquid-conveying amount of single, often can not meet need to larger feed flow application.Therefore, design both can be passed through circuit adjustment transporting velocity and frequency, and mechanically the plunger pump of step-less adjustment single quantity delivered will have better use value again.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, a kind of eccentric adjustable plunger pump is provided, this pump both can pass through circuit adjustment transporting velocity and frequency, and step-less adjustment single quantity delivered mechanically again meets the demand of various application occasions.
For overcoming the deficiencies in the prior art, the present invention takes following technological scheme:
A kind of eccentric adjustable plunger pump, comprise adjustable eccentric roller and plunger pump, it is characterized in that: adjustable eccentric roller comprises big column and small column, between large small column, be loose fit, small column can be filled in big column, small column connect machine shaft and the axis of the two parallel but do not overlap, big column is provided with adjustable countersunk head locking nut, screw front end is conical surface, and screwing screw can make screw front end conical surface extruding small column surface, realizes the abundant locking of large small column; Plunger pump comprises plunger, cylinder body and return spring, and plunger is pumped by the effect of eccentric roller and return spring, and cylinder body lower end is provided with takes over mouth.
Described plunger pump is provided with base plate and lock nut is fixed cylinder body, avoids cylinder displacement in plunger upward and downward process.
Described plunger pump is also provided with ripple gum cover for dustproof and waterproof.
Unclamp the relative position of countersunk head locking nut between can flexible rotating adjusting size cylinder and the angle between large small column mark line, locking nut again, plunger stroke that just can pilot plunger pump, realizes Flow-rate adjustment, if again in conjunction with electronic circuit speed governing, can meet wide range of traffic and carry needs.
The eccentric wheel rotation that plunger pump drives large small column to form by machine shaft, produce the coupled columns extruding on surface beyond the Great Wall, when unclamping, lean on return spring elastic force drive plunger return, realize the to-and-fro motion of plunger, the adapter mouth connecting tube of plunger pump cylinder body lower end, exterior arrangement has the delivery pipeline system of one-way valve to realize the quantitative unidirectional conveying of liquid.
The rotating speed of adjusting machine shaft can pilot plunger reciprocating frequence.
The relative position of adjusting size cylinder can change eccentric degree, thus the each to-and-fro motion stroke size of pilot plunger, and ripple gum cover, for dustproof and waterproof, plays protective separation effect to plunger and spring.
When the mark line of large small column is positioned at the both sides of machine shaft and when into a line, the eccentric wheel cylindrical center of circle that machine shaft axle center and large small column form overlaps, so, the effect of not pushing plunger, even at this moment energising rotation, quantity delivered is also zero.
Unclamp screw, rotation adjusting size cylinder mark line is in the same side of machine shaft and to directly, locking nut again, at this moment plunger reaches range lower dead centre state, the rotation of energising rear motor rotating shaft band movable eccentric wheel, plunger is followed upwards and is upheld under spring force effect, so that arrives plunger range upper dead center state.At this moment machine shaft continues driven rotary, plunger is again by downward Compress Spring progressively, to finally reaching again plunger lower dead centre state, machine shaft continuously rotates, the eccentric wheel that drives large small column to form, repeatedly push, unclamp plunger, realize the range to-and-fro motion of plunger, this eccentric state has maximum fluid quantity delivered.
As feed flow that need be between maximum and minimum, mark line that can adjusting size cylinder, in mutual plumbness, is at this moment the plunger stroke lower dead centre of plunger stroke placed in the middle, arrives plunger motion stroke upper dead center after machine shaft driven rotary.
Unclamp screw, can two of mark lines, to any position locking nut in the middle of straight state, obtain required plunger stroke by adjusting size cylinder, reagents is carried.
Compared with prior art, beneficial effect of the present invention is:
Fully application taper fit, easily fills and also easily takes apart, and before screw, pointed cone extruding small column surface, promotes the cooperation between cylinder and small column, is convenient to unclamp or lock;
Regulate convenient and simplely especially, can regulate easily and grope best eccentric vibrating position, the best that reaches plunger pump is used state;
Simple and reasonable durable, cost is lower, can realize the adjustable continuously of plunger stroke by the relative position of step-less adjustment machinery, so convenient practicality; Motor speed-regulating in conjunction with electronic circuit can the large-scale reagent Flow-rate adjustment of convenient realization be carried.
