Report in WORLD PUMPS JULY 1985, in Roller Pumps forIndustrial Applications one literary composition, the effect of having introduced typical R oller pump is four roller slots, and a roller that adapts with groove is respectively arranged in the groove.But its import and export horn mouth central angle has only about 30 °, can cause enclosed volume also volume fluctuations can take place leaving when importing and exporting like this, and it is unfavorable to bring for the normal operation of pump, and these all are the problems that we need solve.
The purpose of this utility model is for the fluid pressure that makes the roller back side increases, and avoids liquid by rigid extruding.Prevent that simultaneously enclosed volume from leaving the increase when importing and exporting and dwindling, helping the rotor running, the liquid that can not vaporization that makes suction reduces vibrations and noise in the running with regard to outside the excavationg pump.
Another purpose of the present utility model is to be used to carry all kinds of solvents oil, and rotor and roller are in good working environment, improves the life-span of pump.
In order to realize this purpose, the utility model provides a kind of that circular groove, circular groove and liquid outlet communicate, as to be used to carry various liquid novel roller pump that has in pump.Have circular groove on the body during it mainly comprises, this circular groove communicates with liquid outlet; Also can be that the rotor both sides have circular groove, have circular groove on the middle body, this circular groove communicates with liquid outlet; Also can be that the circular groove that respectively has on a circular groove, the middle body on pump cover and the middle body communicates with liquid outlet; Or have on circular groove, the rotor both sides on the middle body and have the circular groove that has on circular groove, the pump cover on circular groove, the middle body and communicate with liquid outlet.Four roller slots are arranged on the rotor, a roller that adapts is respectively arranged in the groove.The effect of circular groove is the pressure of liquid in balanced four roller slots, and makes this pressure equal outlet pressure, to strengthen the power that roller is adjacent to the pump housing.Four rollers of design can be eliminated the fluctuation of enclosed volume.Handing over a section position in pump housing import and export with the pump housing is a changeover portion, and the cross section is enlarged gradually, and this can in time draw the liquid in the pump housing enclosed volume, avoids producing enclosed volume and fluctuates.And the enclosed volume fluctuation ratio of general roller pump is 10%.Because liquid is incompressible, the enclosed volume fluctuation can cause mechanical failure.
Below in conjunction with detailed description and the description of the drawings thereof, structure composition of the present utility model, working principle and advantage thereof are done a detailed introduction to implementing an embodiment of the present utility model.
The accompanying drawing of present embodiment is
The schematic representation of the novel roller pump of Fig. 1.
Fig. 2 is the AA generalized section.
As shown in Figure 1 and Figure 2, the novel roller pump structure shown in the present embodiment is as follows.Novel roller pump is made up of liquid entering hole [1], roller [2], roller slot [3], the pump housing [4], bias axis [5], rotor [6], pump chamber [7], liquid outlet [8], pump cover [9], middle body [10], circular groove [11] [12] [13] [14], enclosed volume [15].
A pump chamber [7] is arranged in the pump housing [4], and liquid in-out mouth [1], [8] are cylindrical hole, and its center line parallel moves down rotor axis, and a rotor [6] is installed above the bias axis [5], and rotor [6] is gone up uniform four roller slots [3], and a roller that adapts [2] is respectively arranged in the groove.Roller [2] is by inside and outside two-layer the composition, and internal layer is that steel cylinder, skin are the cylindrical shape cotton garment.Be designed to four rollers and can not produce the wave phenomenon of liquid enclosed volume [15], help the rotor running, make the liquid that can not vaporization or the rigid extruding of suction, vibrations and noise in the running are reduced.Rotor and motor direct connection are installed, and mechanical seal is adopted in shaft sealing.
Go up both sides at rotor [6] and have circular groove [12] [13], have circular groove [14] on the pump cover [9], also have circular groove [11], circular groove [11] and liquid outlet [8] on the middle body [10] and communicate.Roller has improved under action of centrifugal force and has been adjacent to pump housing pressure like this, thereby pumping pressure is improved.The interior circle of circular groove [11] [12] [13] [14] is the bottom land through roller slot, and the cylindrical of circular groove is in order to guarantee the volume of certain circular groove, to be decided by calculating according to liquid flow velocity, and is fixed to guarantee four fluid pressure weighing apparatuses in the roller slot.
The utility model also can only driven circular groove or only driving circular groove on pump cover on the rotor.If but four concentrated opening on rotor of circular grooves, then the intensity of rotor can reduce.Open on pump cover if concentrate, then must do pump cover greatly, cause whole pump structure inhomogeneous.It is just more attractive in appearance only to have circular groove on pump cover, rotor, middle body.
