Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of pump and regulates the choma device by adaptivity.
Background technique
Pump refers to and controlled by prime mover, orders about medium motion, the energy conversion device that is the pressure medium energy by the transformation of energy of prime mover output, and it is mainly used to transport liquid, comprises water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc.; The liquid that also can carry liquid, gaseous mixture and contain suspended solids.By working principle, classify, pump case is divided into positive displacement pump, impeller pump and jet pump.Impeller pump is to drive the liquid at high speed revolution and mechanical energy is passed to carried liquid by impeller.The impeller of impeller pump is arranged in pump case, and is fastened on pump shaft, and pump shaft is moving by the motor straight tape splicing.
Pump is the impeller type multistage pump device of core the most with the adaptivity seal arrangement, and traditional main mode of water pump control ring seal has following two kinds in the market:
The one, the closely spaced choma structure of highi degree of accuracy, mainly be applicable to the water pump that minor axis hangs down load.As Chinese patent application (application number: 200620106723.0) disclose a kind of mouth-ring seal structure of centrifugal pump/vane wheel, the water intake cooperation place of impeller and the pump housing is provided with the cavity consisted of the pump housing and stator, be provided with an O RunddichtringO in this cavity, reason due to pressure difference, the one O RunddichtringO leans against on the pump housing and impeller port ring, and be and be slidably matched, thereby greatly reduced the rotatable parts impeller that cuts off high and low nip and the gap between the fixed component pump housing, improved the whole work efficiency of centrifugal pump.
The 2nd, adopt outside framework oil seal as lip, be applicable to the high-power pump of large flow.As Chinese patent application (application number: the combined sealing structure that 201220301948.7) discloses a kind of spatial guide blade body formula twin-stage Under Water Pumps, there is pump shaft, along pump shaft, once be provided with from top to bottom connecting pipe component, spatial guide blade body, secondary impeller, stage casing and first stage impeller; Connecting pipe component and pump shaft link together, spatial guide blade body and connecting pipe component are fixed, stage casing is connected with the spatial guide blade body, impeller is fixed on pump shaft, and by seal ring, sealed between secondary impeller and spatial guide blade body or stage casing, offer the impeller backflow equalizing orifice of through-hole form on secondary impeller near root along the axial direction of pump shaft, this through hole is connected with the cavity of spatial guide blade body; Be provided with O-ring seals being provided with between spatial guide blade body and pump shaft between the sealing of in-flow single end face word balancing machine, multiple skeleton-type oil seal, bearing support and spatial guide blade body.
Although these above-mentioned structures can play the effect of sealing to a certain extent, but it is when operation, in the water flow process that impeller absorption subordinate stator provides, current can be done the motion that refluxes by the gap of impeller and stator joint, the loss of build-up of pressure is larger, the manufacturing efficiency of pump and quality of product are all lower, and install the requirement of size also higher.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, proposed adaptivity for a kind of pump and regulated the choma device, its technical problem to be solved is: existing pump is large by the adaptivity seal arrangement pressure loss, installation to size require high, manufacturing efficiency and quality of product low.
The purpose of this utility model can realize by following technical proposal: adaptivity is regulated the choma device for a kind of pump, and pump comprises rotating shaft and be set in impeller and the stator in rotating shaft, and it is characterized in that, described stator is plugged on the choma of described impeller; This adaptivity is regulated the choma device and is comprised head part and the Adjusting ring be set in successively on impeller port ring; Form an airtight chamber between described head part and impeller port ring and stator; Described Adjusting ring be arranged in described chamber and and described impeller port ring between be drive fit; There is the reflux liquid that can make the impeller port ring place produce between described head part and impeller port ring and enter the opening one in chamber.
During pump operation, the driven by motor rotating shaft is rotated, thereby drive, is set in the impeller High Rotation Speed in rotating shaft, impeller can absorb the current that stator provides, and in this process, in stator, can produce high pressure, under the effect of high pressure, the current of absorption can produce at the impeller port ring place reflux liquid.The stator that this pump is regulated the choma device by adaptivity is plugged on the choma of impeller, form an airtight chamber between head part and impeller port ring and stator, the reflux liquid produced is from opening one enters in chamber, due to Adjusting ring can along with impeller together High Rotation Speed form and to get rid of the liquid structure, a large amount of reflux liquids are thrown out of, can be not directly by the gap of impeller and stator joint, do not entered in the inner chamber of stator, thereby the pressure restraining farthest higher level's volute space produced is in the chamber formed by head part and impeller port ring and stator, effectively reduce the loss of pressure, improved the efficiency of pump.Simultaneously, regulate the effect of choma device by adaptivity by this pump, reduced to a great extent the requirement of pump to installation dimension, facilitated and manufactured and install.
In above-mentioned pump is regulated the choma device by adaptivity, described adaptivity is regulated the choma device and is also comprised the end part be set on impeller port ring; Part of the described end is arranged in chamber and by described chamber and is divided into chamber one and chamber two; Described opening one is connected with described chamber one; Described Adjusting ring is arranged in chamber one; There is the opening two that can make described chamber one and chamber two be connected between part of the described end and impeller port ring.In the pump operation process, after the reflux liquid that the impeller port ring place produces enters chamber one by opening one place, most of along with Adjusting ring is thrown out of, a very little part is entered in chamber two by opening two places, in the inner chamber that enters stator by the gap between impeller and stator, realizes refluxing.Effect by end part is divided into chamber one and chamber two by chamber, has both realized that the pressure restraining that higher level's volute space is produced of maximum possible, in chamber one, had reduced the loss of pressure.Chamber one and chamber two is interconnected and has guaranteed that impeller not there will be stuck phenomenon in rotation process, has improved the mechanical efficiency of pump integral body simultaneously.
