Description

Twin shaft sealing variable capacity water pump
Technical field
The utility model relates to displacement pump, particularly a kind of twin shaft sealing variable capacity water pump.
Background technique
Displacement pump has stable working, constant flow, characteristics that efficient is high, is applied to many fields; But displacement pump exists lift short, and rated pressure is low, and mechanism is complicated, and it is big to take up room, and is unfavorable for the problem of keeping in repair.
For addressing the above problem, a kind of " variable-volume type multi-chamber hydraulic water pump " proposed in CN201111301270.5, its high-speed rotation with transmission shaft is transformed into the low linear velocity of the rotor that dangles and rolls; The rotor that dangles closely contacts with the active chamber inwall; Stopped liquid and returned and rush down, improved lift, again because rolling friction much smaller than sliding friction; Improve working efficiency, reduced wearing and tearing.But this variable-volume type multi-chamber hydraulic water pump exists following problem to be: 1, the guide way volume is excessive, has taken 25% of effective working space, has reduced working efficiency; 2, guide way is the line contact with the contacting between the rotor of dangling, and sealing effect is poor, leaks easily; 3, complex structure, volume is big, cost is high.
Summary of the invention
The technical problem that the utility model will solve provide a kind of simple in structure, volume is little, cost is low, efficient is high, the twin shaft of good seal performance sealing variable capacity water pump.
The twin shaft sealing variable capacity water pump that the utility model relates to comprises the pump housing, on the pump housing, is provided with suction port and exhaust port; Pump housing inner space is an active chamber; Active chamber is one or more, in the pump housing, along center line axis is installed, and eccentric wheel is installed on axis; On eccentric wheel, be set with the rotor that dangles; Be provided with wearing layer at the active chamber inwall or the rotor outer surface that dangles, at eccentric wheel and dangle and be provided with bearing between the rotor, its special way is: in active chamber, be provided with twin shaft head pilot seal dividing plate; Be respectively equipped with the pilot seal hole at active chamber inwall and two spindle nose corresponding positions that dangle on the rotor with described twin shaft head pilot seal dividing plate, described two spindle noses lay respectively in active chamber inwall and the epitrochanterian pilot seal hole of dangling.
Above-mentioned twin shaft sealing variable capacity water pump, described twin shaft head pilot seal dividing plate is the Z type, and is Spielpassung between two spindle noses and the corresponding pilot seal hole.
The utlity model has following advantage:
1, adopt twin shaft head pilot seal dividing plate to realize guiding, sealing, the volume of twin shaft head pilot seal dividing plate improves working efficiency much smaller than the guide way of original employing greatly.
2, be the arc shaped surface sealing between the twin shaft head of active chamber inwall, dangle rotor and twin shaft head pilot seal dividing plate, than the line contact sealing of original employing, sealing area is bigger, and sealing effect is better.
3, simple in structure, volume is little, and is in light weight, cost is low.

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a compensating plate structural representation among Fig. 1;
Fig. 4 is the B-B sectional view of Fig. 3.
Among the figure: the 1-pump housing, 2-wearing layer, the 3-rotor that dangles, 4-twin shaft head pilot seal dividing plate, 5-composite bearing; The 6-exhaust port, 7-eccentric wheel, 8-pilot seal hole, 9-key; The 10-axis, 11-sealing plate, 12-suction port, 13-compensating plate; 14-divides the chamber plate, 15-active chamber, 16-radial pore, shoulder hole 17.
Embodiment
As shown in the figure; This twin shaft sealing variable capacity water pump comprises the pump housing 1, in the pump housing 1, is provided with one or more active chambers 15, and present embodiment is an example with two active chambers; On the pump housing 1, be provided with a suction port 12 and an exhaust port 6; Adjacent active chamber 15 is separated by branch chamber plate 14, on the pump housing 1, sets up axis 10 vertically, on axis, is connected with eccentric wheel 7 through key 9.Corresponding each active chamber 15 is respectively installed with the rotor 3 that dangles on axis 10, and the described rotor 3 that dangles along the circumferential direction is uniformly distributed with.Dangling is provided with composite bearing 5 between rotor 3 and the axis 10, and making between the two can relative movement.In each active chamber 15, be respectively arranged with Z type twin shaft head pilot seal dividing plate 4; Two spindle nose corresponding positions with described twin shaft head pilot seal dividing plate 4 on active chamber 15 inwalls and the rotor 3 that dangles are respectively equipped with pilot seal hole 8; Described two spindle noses lay respectively in active chamber 15 inwalls and the pilot seal hole 8 of dangling on the rotor 3, and are Spielpassung between two spindle noses and the corresponding pilot seal hole 8.Be provided with polymer composite wearing layer 2 at active chamber 15 inwalls.On the rotor 3 that dangles, be provided with the radial pore 16 of through composite bearing 5, corresponding exhaust port 6 places are provided with sealing plate 11 on the rotor 3 that dangles, in case backflow.In the pump housing 1, be positioned at active chamber 15 both sides and be provided with compensating plate 13, along the circumferential direction distinguish a plurality of shoulder holes 17 on the compensating plate 13, shoulder hole 17 small bore end are all towards active chamber 15.
When work; Axis 10 is given transmission of power eccentric wheel 7 and is dangled rotor 3, through twin shaft head pilot seal dividing plate 4 and eccentric wheel 7 actings in conjunction, defines the movement locus of the rotor 3 that dangles; Through axis 10 and the composite bearing 5 between the rotor 3 of dangling; Making dangles can realize relative movement between rotor 3 and the axis 10, become the rotor 3 that dangles and roll thereby the high angular velocity that axis 10 transmits rotated for the low linear velocity of active chamber 15 inwalls, during rolling and active chamber 15 inwall point of contact be negative clearance; Form low, hyperbaric chamber, liquid is sucked, discharges.
