Abstract
A stroke regulating mechanism of metering pump consists of worm wheel, worm gear, regulating stem and eccentric wheel. It is featured as connecting eccentric wheel with link lever and setting bush between them, firm - joining L form shaft with regulating stem below the regulating stem to use L form shaft to regulate stroke of metering pump.
Description
(1) technical field
The present invention relates to the stroke control mechanism of metering pump.
(2) background technique
Metering pump is the requirement by technological process, realizes the indispensable universal machine of Flow-rate adjustment and accurate measurement.Its main feature is the measuring accuracy height, can regulate by technological requirement by on-stream realization flow, and application area is wider, and row pressure is higher, adopts packing box seal.The stroke control mechanism of present domestic metering pump mainly is a N profile shaft structure, but the processing technology complexity of N type bent axle needs to adopt special machine tooling, to guarantee its precision, the processing cost height; In addition, N type bent axle bears cyclic loading, easily produces faults such as eccentric wear, fatigue fracture inefficacy, has influenced the working life and the reliability of pump.
(3) summary of the invention
In order to overcome part processing difficulty in the prior art, easily to produce wearing and tearing, deficiency that reliability is not high, the stroke control mechanism of the metering pump that the invention provides that a kind of parts machining process is simple, good stability, wearing and tearing is little.
The technical solution adopted for the present invention to solve the technical problems is: the stroke control mechanism of metering pump, comprise worm gear, worm screw, adjustable lever and eccentric wheel, described eccentric wheel connects connecting rod, has lining between described connecting rod and the described eccentric wheel, adjustable lever below and the affixed L profile shaft of described adjustable lever, offer skewed slot on the described L profile shaft, in the described skewed slot guide is installed, be inserted with latch in the described guide, described L profile shaft is with axle sleeve outward, and described axle sleeve is bearing in the pump body by bearing.The periphery symmetry of described axle sleeve is offered two grooves, and an eccentric wheel with breach is placed on the described axle sleeve by the groove on described breach and the described axle sleeve, and described latch passes groove and the described eccentric wheel on the described axle sleeve.
Further, described axle sleeve is outside equipped with outstanding support ring, and connecting rod is arranged on the support ring.
Further again, the bearing of described supporting sleeve is an angular contact ball bearing.
The beneficial effect of the stroke control mechanism of metering pump of the present invention mainly shows: 1. adopt the L profile shaft to regulate the stroke of metering pump, the processing technology of L profile shaft is simple, and force-bearing situation is able to obvious improvement, is difficult for producing wearing and tearing.2. increase supporting ring and be used for bearing connecting rod, connecting rod produces connecting rod with regard to not descending because of conducting oneself with dignity and lining misaligns, the gap is inhomogeneous, the problem of eccentric wear.3. the axially locating of angular contact ball bearing is good, can prevent the play of axle sleeve and worm screw, worm gear effectively and produces wearing and tearing.
(4) description of drawings
Fig. 1 is a sectional arrangement drawing of the present invention.
Fig. 2 is the three-dimensional erection drawing of stroke control mechanism of the present invention.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described.
Embodiment one
With reference to Fig. 1,2, the stroke control mechanism of metering pump, comprise the L profile shaft 5 that adjustable lever 4, adjustable lever below and described adjustable lever 4 are affixed, offer skewed slot 13 on the described L profile shaft 5, in the described skewed slot 13 guide 7 is installed, be inserted with latch 8 in the guide 7, the described L profile shaft 5 outer axle sleeves 6 that are with, described L profile shaft cover 6 is bearing on the bearing 12.The periphery symmetry of described axle sleeve 6 is offered two grooves 14, and is offered eccentric wheel 3 jaggy and be placed on the described axle sleeve 6 by the groove 14 on described breach and the described axle sleeve, and latch 8 passes groove and the described eccentric wheel 3 on the described axle sleeve; Described axle sleeve 6 is connected with worm screw 11, worm gear 10, and eccentric wheel 3 connects connecting rod 1, has lining 2 between connecting rod and the described eccentric wheel.
Motor drives 6 rotations of L profile shaft cover by worm screw 10, worm gear 11 parts, drive places the eccentric wheel 3 on the L profile shaft cover 6 to rotate synchronously, 1 swing of eccentric wheel 3 drive link, and connecting rod connects crosshead, rotatablely moving of eccentric wheel 3 is changed into the to-and-fro motion of crosshead.When adjusting adjustable lever 4 moved axially, guide 7 and straight pins 8 in the skewed slot 13 of L profile shaft also moved thereupon, also produced simultaneously by the eccentric wheel 3 that is connected with straight pin 8 to move radially, and throw of eccentric is changed.In the middle of the running of pump,, change the flow of pump like this, reach the purpose that metering is carried by adjustment stroke.
Embodiment two
With reference to Fig. 1,2, be outside equipped with outstanding support ring 9 in axle sleeve, connecting rod 1 is arranged on the support ring 9.Supporting ring 9 is in order to bearing connecting rod 1.All the other mode of executions are identical with embodiment one.Connecting rod 1 descends because of deadweight in the course of the work, causes connecting rod 1 and lining 2 gap inequalities, and insufficient lubrication produces eccentric wear, easy serious problems such as inefficacys, the supporting ring wearing and tearing of connecting rod and connecting rob bushing afterwards is set is able to obvious improvement.
Embodiment three
With reference to Fig. 1,2, the bearing of supporting sleeve is an angular contact ball bearing.All the other mode of executions are identical with embodiment one.The axially locating of angular contact ball bearing is good, can prevent that axial float from exceeding scope of design, has guaranteed the position degree of worm screw 10 with worm gear 11, has prevented worm screw 10 and the eccentric wear that worm gear 11 produces because of axial float is excessive, has improved reliability of products.
Embodiment four
With reference to Fig. 1,2, the bearing of supporting sleeve is an angular contact ball bearing.All the other mode of executions are identical with embodiment two.The axially locating of angular contact ball bearing is good, can prevent that axial float from exceeding scope of design, has guaranteed the position degree of worm screw 10 with worm gear 11, has prevented worm screw 10 and the eccentric wear that worm gear 11 produces because of axial float is excessive, has improved reliability of products.
