Abstract
This invention relates to double eccentric flexible pumps, which comprises main shaft, left eccentric wheel, right eccentric wheel, left crush wheel, right crush wheel, left transmission tube, right tube band wheel and pump wheel. The invention is characterized by adopting two eccentric wheels to Drive two transmission tubes for work with high efficiency and small vibration and suitable for Medicine, foods, chemicals transmission.
Description
Technical field:
The present invention relates to a kind of electromechanical assembly of conveyance fluid, it is a kind of new peristaltic pump, promptly a kind of novel peristaltic pump.
Background technique:
Existing peristaltic pump is to adopt duplex bearing (or three bearings) extruding wheel, when carrying liquid, and the driven by motor main axis rotation, ring rotates with main shaft in the extruding wheel, and the extruding wheel outer shroud contacts with delivery hose is intermittent, and to same direction squeezing tube, fluid is transferred out endlessly.This peristaltic pump efficient is not too high, and extruding wheel is more serious to the delivery hose wearing and tearing, and the volume of pump is also bigger, and can only be used for the single tube suction, since uneven, thus certain vibrations are arranged, also influential to parts life-span.
Summary of the invention:
The present invention can solve the deficiencies in the prior art preferably, and it provides a kind of double eccentric wheel type hose pump, can drive two flexible pipes simultaneously and aspirate transportation work, has improved transfer efficiency greatly, has reduced mechanical shock.
Realize a kind of double eccentric wheel type hose pump of the present invention, comprise main shaft, left eccentric wheel, right eccentric wheel, left extruding wheel, right extruding wheel, left delivery hose, right delivery hose, pump housing shell and belt pulley etc., described left and right eccentric wheel is connected on the main shaft, described left and right extruding wheel is connected on the left and right eccentric wheel, described left and right eccentric wheel, left and right extruding wheel, left and right delivery hose and main shaft are installed in the pump housing shell, it is characterized in that the extruding wheel of peristaltic pump adopts two eccentric wheels.
As improvement of the present invention, described double eccentric wheel type hose pump is characterized in that driving simultaneously two delivery hoses and aspirates transportation work.Adopt two-tube work, improved working efficiency greatly, increased pressure.Because left and right eccentric wheel is fixed on the main shaft by 180 degree symmetries, has solved dynamically balanced problem, has reduced the vibrations of the pump housing.
As a further improvement on the present invention, described double eccentric wheel type hose pump is characterized in that left and right left extruding wheel is separately fixed on the left and right eccentric wheel, and is fricton-tight between them.Extruding wheel in this device can adopt rolling bearing, and when contacting with the delivery hose extruding owing to extruding wheel, tightr each other and fricton-tight, therefore, delivery hose is difficult for being worn, and has improved the working life of delivery hose greatly.
Further improve again as of the present invention, described double eccentric wheel type hose pump, the material that is transferred that it is characterized in that double eccentric wheel type hose pump does not contact the pump housing, and therefore no matter being transferred material has severe corrosive or receptance also can not corrode and the corrosion parts, has improved parts life-span.The pump housing need not sealing in addition, so easy processing, easily manufactured, with low cost.
Further improve again as of the present invention, described double eccentric wheel type hose pump is characterized in that main shaft one end can directly connect motor, also can connect motor by speed changer again.This double eccentric wheel type hose pump volume is little, simple in structure, easily realize automation.
Realize a kind of double eccentric wheel type hose pump of the present invention, have efficient height, vibrations are little, easy to manufacture, volume is little, cost is low, purposes is wide, automaticity is high advantage.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a structural representation of the present invention.
Embodiment:
As shown in Figure 1 to Figure 3, realize a kind of double eccentric wheel type hose pump of the present invention, comprise main shaft 1, left eccentric wheel 2, left extruding wheel 3, left delivery hose 4, right eccentric wheel 5, right extruding wheel 6, right delivery hose 7, pump housing shell 8, belt pulley 9 etc.Left side eccentric wheel 2, right eccentric wheel 5 are connected on the main shaft 1 and maintain static, and left extruding wheel 3, right extruding wheel 6 are separately fixed on left eccentric wheel 2, the right eccentric wheel 5.A left side extruding wheel 3, right extruding wheel 6 can adopt ball bearing, and promptly bearing inner sleeve is fastened on the eccentric wheel motionlessly, and bearing outside directly pushes delivery hose 4 and 7, and contact is tight and fricton-tight between them.Main shaft 1, left eccentric wheel 2, left extruding wheel 3, left delivery hose 4, right eccentric wheel 5, right extruding wheel 6, right delivery hose 7 all are installed in the pump housing shell 8.The main shaft 1 of double eccentric wheel type hose pump can directly be connected with motor by belt pulley 9, is rotated by driven by motor.Motor also can be connected with the main shaft 1 of double eccentric wheel type hose pump by axle connection or speed change gear.
In Fig. 3 embodiment's structural representation, motor can adopt microcomputerized control, stepless speed regulation.The transporting velocity of double eccentric wheel type hose pump, available stream value numeral shows.Left side delivery hose 4, right delivery hose 7 can adopt the manufacturing of import silicone rubber material, and specific use should meet the sanitary standard of biochemistry, medical domain use.
This kind peristaltic pump has transfer efficiency height, vibrations are little, simple in structure, easy to manufacture, cost is low, volume is little, purposes is wide advantage.Being particularly suitable for aspects such as medicine, food, chemical industry, breed and family carries some to have medium receptance, thickness, severe corrosive, that have ablation, that purity requirement is high and that contain certain granules shape material.
Claims (5)
