Abstract
The utility model relates to a ring type displacement pump, the device are including the motor and the pump body of equipment in the frame, wherein utilize the bent axle tip of bearing equipment in the pump body to peg graft in the axle sleeve of driving disk, and the quiet dish of adorning on the pump body admittedly has a ring shape platform at least, and the quiet bottom of the dish portion of platform both sides processing has medium sunction inlet and discharge port, inhales, arranges and keeps apart through the baffle of installing in circular platform opening slide between the mouth, and the ring shape platform equipment of quiet dish is in the corresponding ring shape intracavity of driving disk. The component has simple shape, easy processing, small volume, light weight, lower manufacturing cost and stable operation, and can obviously improve the service life and the working efficiency.
Description
The utility model relates to a kind of rotarydisplacement pump, particularly a kind of ring type displacement pump.It is applicable to conveying gas or liquid and other medium.
Existing displacement pump mainly is divided into two big classes.One class is a reciprocating pump, generally based on reciprocating pump, is characterized in that manufacturing process is simple, manufacture cost is lower, has become a kind of comparatively widely displacement pump of current application.But because of having reciprocating member in its structure, so galloping is unsuitable for running up, and easily damaged parts is more, and the life-span is low.Another kind of is drum pump, mainly contains vane pump, rolling piston pump, screw pump and vortex pump etc.Be characterized in running steadily, simple in structure, few easy workout part, the life-span is long.But because its manufacturing process complexity, the special construction of some component also must utilize special device to process, so its application area is extensive not as good as reciprocating piston pump.
The purpose of this utility model provides a kind of ring type displacement pump, and its member simple shape, easily processing, volume is little, in light weight, manufacture cost is lower, and running steadily can obviously improve working life and working efficiency.
The purpose of this utility model is achieved in that this device comprises the motor and the pump housing that is assembled on the frame, the crankshaft end of wherein utilizing bearing pack to be contained in the pump housing is plugged in the axle sleeve of Moving plate, the quiet dish that is packed on the pump housing has a ring platform at least, the quiet tray bottom of platform both sides is processed with medium suction port and floss hole, inhale, arrange between the mouth and isolate by the dividing plate that is installed in the circular platform open slideway, the ring platform of quiet dish is assembled in the corresponding annular cavity type of Moving plate.
Because the utility model adopts bent axle to drive Moving plate and rotates around quiet dish axle center in quiet dish, form the variation of pump housing internal volume, so the task of finishing fed sheet of a media by the suction port and the floss hole of quiet dish is so that it removes the running with rotary pump is steady, outside the low advantage of noise, specific volume is little mutually with vane pump, in light weight, and because of relative velocity between running gear much smaller than vane pump, so surface friction drag is little, few easy workout part, long service life.Compare with the plug pump that rolls, under the situation of same capacity, its volume only is the 60-70% of rolling piston pump, and weight is also light.This device major part simple shape, processing easily is so its manufacture cost is lower than screw pump and vortex pump.Therefore, the utility model is easy to utilize.It can satisfy the performance requirement of air pump, water pump, oil hydraulic pump, vacuum pump, can make various working pumps.
Below in conjunction with accompanying drawing the utility model is further described.

Describe concrete structure of the present utility model in detail according to Fig. 1-7.This device comprises parts such as the motor 1 that is assembled in frame 14, the pump housing 13, bent axle 7, quiet dish 11, Moving plate 12.Wherein bent axle 7 utilizes bearing 5,6, locking nut 3, gland 4 to be packed in the pump housing 13, and an end of axle joins by coupling 2 and motor shaft.The other end of bent axle 7 is plugged in the axle sleeve of Moving plate 12, and the ring platform of the annular cavity type of Moving plate 12 and quiet dish 11 fits together.Quiet dish 11 utilizes end cap 9 to be packed on the pump housing 13.Ring platform on the quiet dish 11 has one at least, the quantity of its ring platform is specifically determined according to pump performance, quiet tray bottom in ring platform both sides is processed with medium suction port 17, floss hole 15, the ring platform of inhaling, arranging between the mouth is provided with open slideway 16, and, isolate and inhale, arrange mouth by being installed in the dividing plate 8 in this open slideway.The open slideway position of dividing plate 8 is installed concentrates the homonymy (as shown in Figure 2) that is set in parallel in quiet dish, or disperse to interlace to be arranged on the angled position of Jing Panshang (as shown in Figure 4).The required pump performance of its main foundation requires and decides.The media discharge mouth 15 of slideway both sides, the position of suction port 17 are provided with corresponding thereupon.When discharge medium is compressible fluid, floss hole 15 dress one-way valves, otherwise do not adorn one-way valve.The quantity of the annular cavity type of Moving plate 12 looks the quantity of ring platform of quiet dish 11 is corresponding to be determined.The length of dividing plate 8 should be decided (as shown in Figure 7) with adjacent two ring spacings on the Moving plate 12.Be processed with two separate spaces on the end cap, be with a floss hole 10 on one of them separate space, be with a suction port on another separate space.This floss hole communicates with floss hole 15 on the quiet dish 11, and the suction port on suction port and the quiet dish 11 communicates with the suction port 17 on the quiet dish 11.
During work, motor 1 drives bent axle 7 and rotates, and the Moving plate 12 that drives axle head rotates around the axle center of quiet dish 11, the internal ring wall of Moving plate 12 annular cavity types is contacted with the internal surface of quiet dish 11 ring platforms, the external annulus of Moving plate 12 annular cavity types contacts with the outer surface of quiet dish 11 ring platforms simultaneously, dividing plate 8 in the open slideway then contacts with the inside and outside ring wall of its annular cavity type in Moving plate 12 whole rotation processes all the time, forms the volume of a pair of variation.Present embodiment adopts the Moving plate 12 of two annular cavity types, the quiet dish 11 of two ring platforms, so just form the volume of two pairs of variations, by that analogy, then can form corresponding variable volume, reaches the revolution flow of desired pump.
