The inlet and the outlet are not blocked and cut by the displacement of the circumference surface of the ring sheet in the axial direction, the inlet is free from the reaction of the centrifugal force of the ring sheet, fluid can pass through the inlet to the cavity of the cylinder swimmingly, and the volume efficiency is increased.
Description
Ring plate rotating piston pump is the long-pending formula pump of a kind of rotary volume-variable, rotary-piston is the ring plate of the ripple song that rotates in circular cylinder, be positioned at the baffle plate of cylinder groove and ring plate kissing and separate and inhale chamber, row chamber and move back and forth at groove, be mainly used in the conveying of liquid along with the rotation of ring plate.
The ring plate rotating piston pump of CN1044518 number record of state's invention patent application prospectus in August 8 nineteen ninety, the pump housing that has circular cylinder is arranged, the axle of pump is positioned at the center line of circular cylinder and cooperates the waveform ring plate of rotary-piston for being connected as a single entity and rotating with the axis with axle with the bearing of pump in circular cylinder; The ring plate side face of waveform and side convex surface respectively with the side face of circular cylinder and side movingly; Axial circular casing wall across ring plate has groove, and baffle plate and ring plate in the groove match; The circular cylinder side face of groove both sides has leg-of-mutton import, outlet.Along with the rotation of ring plate, baffle plate reciprocally swinging in groove is divided into the suction chamber and the row chamber of variation with the chamber of ring plate both sides, sucks, discharges from outlet from import continuously.But import is the side face at circular cylinder, with the side face of ring plate vis-a-vis, the ring plate of high speed rotating makes liquid produce centrifugal force, the centrifugal power of import is opposite with the direction that liquid flows into, and the inflow that has hindered liquid widely enters inhales the chamber, has reduced the working efficiency and the volumetric efficiency of pump.Next be ring plate at rotary course, make axial displacement in import and exit position and the liquid that comes plug-back to cut to enter and discharge, also influenced flowing and the working efficiency of pump of liquid.
The purpose of this utility model provides a kind of suction smoothness, the improvement that molten long-pending efficient is higher ring plate rotating piston pump.
Ring plate rotating piston pump of the present utility model still has the pump housing with circular cylinder, the axle of pump is positioned at the center line of circular cylinder and matches with the bearing of the pump housing, the ring plate of waveform is positioned at circular cylinder and fixedlys connected with axle and is integral, ring plate side face and circular cylinder side face are movingly, the side convex surface of ring plate waveform and circular cylinder side are movingly, the wall of circular cylinder axially have a groove, groove is equipped with baffle plate, baffle plate breach and ring plate kissing, its structural feature is that the circular cylinder side walls of groove both sides has import, outlet.Facing the wall and meditating in circular cylinder week of groove both sides preferably also has dihedral import, outlet.Like this, the fluid of the cavity of suction, excavationg pump is import, the outlet that has through circular cylinder side walls, is not subjected to the influence of ring plate axial displacement, not by stifled the cutting of ring plate side face axial displacement, makes to suck and discharges smoothness.Particularly be located at the import of circular cylinder side walls, be not subjected to the reaction of ring plate centrifugal force, can make fluid waltz through the cavity that import enters cylinder, improved volumetric efficiency widely.Also still have dihedral import, outlet as facing the wall and meditating, the aperture of import, outlet is increased greatly, reduced the resistance of import, outlet, increased to suck and discharged reliability in circular cylinder week.The protruding side circumferential width of ring plate waveform generally be less than or be approximately equal to the groove circumferential width add import and the outlet circumferential width.In order not allow the import of circular cylinder side walls, the cavity conducting that cylinder is passed through in outlet or the chance that reduces conducting, and making the import of circular cylinder side walls, outlet open timely, close, the protruding side circumferential width of ring plate waveform preferably equals or is slightly larger than the groove circumferential width to add import and outlet circumferential width.
The utility model with compare by technology, the resistance that sucks and discharge reduces widely, has improved the working efficiency of pump; It is smooth more to make fluid flow through import, the outlet of pump, particularly can in time waltz through the cavity that the import inflow pump constantly increases, and reduces cavitation phenomenon, has improved the volumetric efficiency of pump widely.
Accompanying drawing has been represented a kind of structural representation of the utility model ring plate rotating piston pump, and wherein Fig. 1 is main sectional view, and Fig. 2 is the sectional view of its A-A direction.
Example below in conjunction with accompanying drawing further specifies the utility model.This ring plate rotating piston pump has the pump housing with circular cylinder, also has axle, waveform ring plate, baffle plate.The pump housing is made up of body 1 and two end caps 2.The cylindrical cavity of body band, the horizontal top of the cylindrical cavity of body are provided with import 9 and the outlet that is in communication with the outside, and import and outlet the inner are the import and the outlet 7 of dihedral.Two end cap is loaded on the two ends of cylindrical cavity, and with the circular cylinder of body structure, the interior edge face of end cap is the side of circular cylinder.Side face and side walls between circular cylinder upper end import and the outlet have axial groove, and baffle plate 4 is housed in the groove.Baffle plate breach and ring plate kissing, form movingly.Groove end covers at two sides inner surface has import 10, the outlet of rectangle.The other end of rectangular inlet, outlet is at the circumferential surface of end cap and be communicated with 8 with import, the outlet of body respectively.The axle 3 of cylinder pump is positioned at the center line of circular cylinder and matches with the bearing at pump housing end cap middle part.The waveform ring plate 5 of rectangular cross-section is positioned at circular cylinder and fixedlys connected and be integral with axle by its inboard sleeve, ring plate side face and circular cylinder side face movingly, the side convex surface of ring plate waveform and circular cylinder side be end cap inner face movingly.Like this, suck, the fluid of the cavity of excavationg pump is import, the outlet that has through circular cylinder side walls through the import of dihedral and outlet but also a large amount of fluids not only, not by stifled the cutting of ring plate side face axial displacement.This just makes the aperture of import, outlet increase greatly, has reduced the resistance of import export, makes to suck to discharge smoothness.Particularly be located at the import of circular cylinder side walls, be not subjected to the reaction of ring plate centrifugal force, can make fluid waltz through import and enter cavity, improved volumetric efficiency widely.After measured, compare with ring plate rotating piston pump not with the same specification of the import of circular cylinder side walls, outlet, ring plate rotating piston pump volumetric efficiency of the present utility model has improved 45 percent, be 40% by the volumetric efficiency of the ring plate rotating piston pump of technology promptly, and ring plate rotating piston pump volumetric efficiency of the present utility model is 85%.For the protruding side that makes the ring plate waveform do not allow circular cylinder side walls import, outlet conducting or reduce the chance of conducting, the protruding side circumferential width of ring plate waveform is to equal the groove circumferential width to add import and outlet circumferential width.
