Abstract
The invention discloses a hydraulic self-adsorption device used in pump, which can be mounted on one end of water pump without self-adsorption function, or mounted on the axle of driving motor of water pump. Said invention is a water annular vacuum pump, which comprises an auxiliary axle, a sliding coupler, an auxiliary key, a sliding key, a water annular wheel, a coupler spring, a frame, a gas chamber, a pressure control valve, a gas extraction tube, a piston, and a hydraulic tube. Wherein, the sliding coupler via auxiliary axle and auxiliary key is connected to the pump axle of water pump to synchronously rotate or stop; the hydraulic tube that through to the outlet of water pump uses the pressure change at the outlet to control the position of sliding coupler; therefore, the sliding coupler will rotate the water annular wheel when the water pump is started; and after the water pump is started, it will depart from water annular wheel without rotating water annular wheel. The invention uses the original power of water pump without additional power; and when the water pump has been started, it will automatically stop.
Description
Affiliated technical field
The present invention relates to a kind of self-priming apparatus, on especially a kind of pump shaft that is contained in water pump, make the water pump that does not have self-absorption function originally realize the self-priming apparatus of self-absorption function, belong to field of fluid machinery.
Background technique
Generally be contained in the above water pump of the water inlet pool water surface, all need to install bottom valve, and full of liquid could proper functioning in inlet pipeline.But bottom valve can increase hydraulic loss when pump working, cause energy waste.Also do not adorn bottom valve and with the vacuum pump diversion of bleeding, make that pump can proper functioning, but vacuum pump is relatively more expensive, and vacuum pump cooperates with the work of water pump, also can increase managerial trouble or increase the automatic expense of controlling.The structure of the pump housing of also changing realizes self-priming, but the hydraulic loss of self-priming structure is all very big.Number of patent application is model utility one Strong self priming pump of CN200320112451.1, self-priming apparatus is contained in the axle head of drive motor, drive reciprocating motion of the pistons by connecting rod and realize air-breathing, scavenging action, though the structure of this self-priming apparatus is simpler than vacuum pump, some problems of narrating have previously also been solved, but rate of fault is than higher, and still there are deficiency in noise and vibration greatly during work.
Summary of the invention
In order to overcome the deficiency of existing self-priming apparatus, the invention provides a kind of new strong self-priming apparatus, the expense that it can make large pump only add half platform minipump just can realize the bleeding function of diversion, and also noise and vibration are little, the functional reliability height.
Technological scheme of the present invention is: according to the principle of Nash hytor, by additional shaft, slip coupling, additional key, slide key, the water ring wheel, annular space on the water ring wheel wheel hub, the coupling spring, housing, air chamber, pressure controlled valve, exhaust pipe, piston and hydraulic control pipeline etc. are formed a water ring type strong self-priming apparatus, be contained in pump shaft one end of the water pump that does not have self-absorption function originally or the axle head of water pump drive motor, its main innovation is: slip coupling links together all the time by the pump shaft of additional shaft and additional key and water pump, with pump shaft rotation synchronously or simultaneously static, the hydraulic control pipeline that communicates with the pump body outlet utilizes the variation of pressure before and after starting mode of pump of pump body outlet, the control slip coupling changes the position, make the position of slip coupling when starting mode of pump, drive the rotation together of water ring wheel, position behind starting mode of pump does not drive the rotation of water ring wheel with the disengagement of water ring wheel.
The additional shaft of strong self-priming apparatus is to be contained in pump shaft one end of the water pump that does not have self-absorption function originally or the axle head of water pump drive motor, static with the pump shaft rotation synchronously or the while of water pump, be to be slidingly matched between additional shaft and the slip coupling, and additional key driven rotary by a loose fit, slip coupling and water ring wheel also are slidingly matched, also pass through the slide key driven rotary of a loose fit, wherein additional shaft and slip coupling are to link together with the pump shaft of water pump all the time, rotation synchronously or simultaneously static, and the water ring wheel just rotates synchronously at the pump shaft of starting mode of pump stage and water pump, and pass through housing, air chamber and exhaust pipe are realized the absorbent function of bleeding to water pump, exhaust pipe has a pressure controlled valve on its circuit, and the outlet of receiving pump body with the hydraulic control pipeline.Before the starting mode of pump, there is liquid in the housing of self-priming apparatus, during starting mode of pump, the water ring wheel makes it to have the ability of bleeding with exhaust by the liquid in the housing, and along with the rotation of water ring wheel, the gas in the pump body sucks housing from exhaust pipe, and from housing, discharge, after the gas in the pump body was drained, water pump just can suct liquid from water inlet pool, made the water pump proper functioning.At this moment the high pressure liquid of exit of pump is known from experience the pressure controlled valve of closing automatically on the exhaust pipe, simultaneously, highly pressurised liquid enters an end of piston by the hydraulic control pipeline, promoting piston and slip coupling moves vertically, make slide key move to the position of the annular space on the water ring wheel wheel hub, be the keyway that slide key has broken away from the water ring wheel, the water ring wheel is no longer rotated with the pump shaft of water pump, thus the excessive power drain when having avoided the water pump proper functioning.When water pump stopped, the pressure of exit of pump reduced rapidly, and the pressure of hydraulic control pipeline and piston one end decreases, and slip coupling relies on the spring force of coupling spring also just to reset.Water pump startup next time repeats said process.
The invention has the beneficial effects as follows, the water pump that adopting the present invention to make does not have self-absorption function originally obtains very strong self-absorption function, and the present invention utilizes first wife's dynamically working of water pump, do not need to dispose in addition power, and after startup work is finished, the present invention can stop power consumpiton automatically, and the present invention also has the Nash hytor reliable operation, rate of fault is low, operational noise is little and vibrate little advantage.
