Abstract
The utility model is a diesel pump which combines the diesel engine with the centrifugal pump, the characters are that a catheter is arranged on the outlet of the water pump and communicated to the suction pipe of the diesel engine, an unidirectional check valve is provided on the outlet of the water pump, and a step valve is arranged at the suction pipe of the diesel engine; the air in the water pump can be discharged through the charging process of the diesel engine without filling water, and the inspiration, the exhausting, and the pumping water process can be completed at the same time, the evacuation is complete and the pumping process is fast.
Description
The utility model belongs to the agricultural machinery and implement technical field, the self-priming pump that particularly a kind of diesel engine, centrifugal water pump combine.
Water pump is a kind of requisite agricultural machinery and implement in agricultural production, is mainly used in the water that extracts in underground water or the river course and carries out the soil irrigation.Now the rural area generally all is to adopt Ordinary Centrifugal Pumps, and this kind centrifugal pump mainly is made up of the blade in intake pipe, outlet pipe and the pump housing, the operation of drawing water of the high speed rotating by blade.The diversion but this kind water pump must be annotated before drawing water could run well behind the air in the emptying pump housing, brings very big trouble to use.Particularly in remote districts or underground water when dark, need a large amount of diversions of filling, just can run well, use inconvenience.
Notification number is 2373596 model utility, a kind of water pump elbow, the patent No. is 99220882, proposes for addressing this problem, and main structure is conduit that links to each other with manual picotan of design on elbow, be provided with an one-way sealing valve in the elbow, the seldom diversion of only need annotating during use gets final product emptying, carries out work, but when water level is dark, not diversion but still need are annotated, and the emptying effect is undesirable, the tired lock of operation.
The diesel pump that provides a kind of diesel engine, centrifugal water pump to combine is provided the purpose of this utility model, utilizes the breathing process of diesel engine to come air in the emptying water pump.
The utility model is achieved in that
Diesel pump, mainly be made up of diesel engine, centrifugal water pump, link to each other by belt between the two, water pump is provided with outlet pipe, the upper end-hole place of this outlet pipe is a water outlet, it is characterized in that: above-mentioned outlet pipe also communicates with the sucking pipe of diesel engine by a conduit; The water outlet of water pump is provided with one and ends valve unidirectional time, and the sucking pipe of diesel engine is provided with a stop valve; On the catheter port at outlet pipe place, also be provided with an air valve.
After the utility model adopts above structure, can utilize the breathing process of diesel engine to come the interior air of emptying water pump, the diversion of need not annotating, air-breathing, exhaust, pump process is disposable finishes, emptying thoroughly, draw water rapidly, only need to get final product several seconds evacuation of air, opening, closing automatically and finish of while valve has effect simple and practical, easy for operation, do not influence any performance of diesel engine and water pump, during groundwater abstraction, inhale journey and can reach 8 meters.
Accompanying drawing is a kind of structural representation of the present utility model;
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
In the accompanying drawing, 1 is that diesel engine, 2 for temporary storage, 10 for float valve, 11 is manual-lock valve for air valve, 9 for ending valve, 7 for unidirectional time for stop valve, 8 for air-strainer, 6 for conduit, 5 for outlet pipe, 4 for water pump, 3.
As shown in drawings, the utility model is a kind of diesel pump, mainly is made up of former diesel engine 1, centrifugal water pump 2, and diesel engine 1 is provided with the sucking pipe that has air-strainer 5; The main structure of water pump 2 comprises: the pump housing, blade and outlet pipe 3, suction sleeve, blade pass are crossed belt and are linked to each other with diesel engine 1, and the upper end-hole place of outlet pipe 3 is a water outlet.On the water outlet of water pump 2, be provided with one and end valve 6 unidirectional time, be communicated with a conduit 4 ending for this unidirectional time on the outlet pipe 3 of valve 6 bottoms.Above-mentioned conduit 4 adopts rubber to make, and the other end communicates with the sucking pipe of diesel engine 1.Be provided with a stop valve 7 on the sucking pipe of air-strainer 5 bottoms, this stop valve 7 is the baffle plate that can close sucking pipe; This baffle plate is provided with the rotatingshaft in an inclined to one side center of circle, and rotatingshaft is provided with a handle outward.On conduit 4 ports at outlet pipe 3 places, also be provided with one and can only and can stop the air valve 8 that water passes through, but this air valve 8 mainly is made up of the cortex closure plate that a waterstop that is blocked on the suction sleeve reaches closure catheter for closing 4 by air; When pump housing internal memory had air, air valve 8 was in open mode, when in the pump housing when suction sleeve enters water, the water slug waterstop, drive closure plate closes ducts 4.
For increasing Security, also has a temporary storage 9 at conduit 4 medium positions, this temporary storage 9 is the closed container that is provided with float valve 10 in, can be installed on the frame of diesel engine 1, the suction port of container is positioned at the container bottom, the air outlet is positioned at container top, after part water enters conduit 4, enter again in the temporary storage 9, float valve 10 is closed under the water buoyancy function, and in container, anti-sealing enters diesel engine 1 by conduit 4 with water storage temporarily.
A manual-lock valve 11 also can be set on conduit 4.
Working procedure is as follows: start diesel engine 1, after working well, handle with sleeve makes stop valve 7 close the air inlet of air-strainer 5, and this moment, diesel engine 1 can only suck the pump housing and the interior air of suction sleeve by conduit 4.On the outlet pipe 3 unidirectional time simultaneously ends valve 6 and is in closed condition, and it is unimpeded that the air valve 8 on the conduit 4 then keeps.Blade is high speed rotating under the drive of diesel engine 1.Along with the minimizing of the pump housing and air-breathing inner air tube, and form vacuum gradually, simultaneously under the effect of blade, water is constantly lifting in suction sleeve, after water enters outlet pipe 3 from the pump housing, the water slug waterstop that rises, thus drive closure plate closure catheter for closing 4, air valve 8 is closed, water ends valve 6 by unidirectional time and flows out from water outlet, and water pump 2 runs well and draws water.After above-mentioned air valve 8 was closed, because the getter action of diesel engine 1 makes the baffle plate on the stop valve 7 overturn along rotatingshaft, thereby opens the path of air-strainer 5, diesel engine 1 was by air-strainer 5 air-breathing, normal operations.
If careless manipulation, part water flow in the conduit 4, will enter in the temporary storage 9 by float valve 10 automatic closure catheter for closing 4, prevent that diesel engine 1 from intaking.When machine needed stall, the water in the manual-lock valve 11 on the closure catheter for closing 4, the pump housing and suction sleeve still can keep former water level, can not fall after rise.
