Description

The self-sucking energy-saving water pump

The utility model relates to non-varactor pump, particularly centrifugal priming of pump.

At present, at middle-size and small-size centrifugal pump, in the mixed flow pump (as BA, HB type pump), adopt the starting of filling topping up mostly, in large centrifugal pump, mixed flow pump, then adopt another vacuum pump (as water ring pump) to bleed and draw the liquid starting, the topping up starting will be poured in the pump by other water source water intaking, Pump Suction Nozzle also will have bottom valve, increased suction resistance during work, adopting another pump to bleed then need increase the workload of installation, starting also needs another air pump after the termination of pumping, thus need there be a pump standby for a long time, so the starting problem of centrifugal pump is failed fine solution always.

The purpose of this utility model provides a kind of self-sucking energy-saving water pump that has self-priming apparatus when starting.

The purpose of this utility model realizes by following technological scheme, the self-sucking energy-saving water pump has main shaft, impeller, spiral case, bearing, cartridge housing and base, it is characterized in that on main shaft, having the cam cover of main axis rotation relatively, between cam cover and the main shaft clutch is arranged, have a cylinder block on bearing support, the piston that is driven by the cam cover is arranged in the cylinder block, the suction port of cylinder block has suction valve and connects the pipe of the water outlet of pump spiral case, the exhaust port of cylinder block has expulsion valve and connects the pipe of atmosphere, is connected to one-way valve on the water outlet of pump.

Cam put can be equipped with powered pulley or with the direct-connected flange plate of motor.

Can be equipped with on the main shaft powered pulley or with the direct-connected flange plate of motor.

The lock screw of limited fixed piston position on the cylinder block.

Owing to having had piston and suction, expulsion valve, the air of pump spiral case and suction pipe, discharge tube can having been discharged and water sucted centrifugal pump is started to work, saved the work of pouring water and bottom valve, reach the self-priming purpose, saved energy.

Below, in conjunction with the accompanying drawings and embodiments, self-sucking energy-saving water pump of the present utility model is explained in detail.

Fig. 1 is first kind of embodiment's of the utility model self-sucking energy-saving water pump a front view;

Fig. 2 is the secondary view of this self-sucking energy-saving water pump along A-A face among Fig. 1;

Fig. 3 is second kind of embodiment's of the utility model self-sucking energy-saving water pump a front view.

As Fig. 1 Fig. 2, the self-sucking energy-saving water pump has main shaft 2, impeller 13 is housed on the main shaft, impeller outer has spiral case 14, have bearing 8 and cartridge housing 9 on the main shaft, cartridge housing 9 is contained on the base 17, the main shaft 2 of present embodiment passes through clutch (as jaw clutch by powered pulley 6, friction lamella clutch etc.) drive, powered pulley 6 is fixed on one can be on the cam cover 7 that rotates on the main shaft 2, outside the cam cover 7 bearing 8 is arranged, one side of belt pulley 6 or cam cover 7 has the junction plane with clutch 5, the other end of cam cover has cam, it is between two bearings 8 of main shaft, one cylinder block 10 is arranged on cartridge housing 9, cylinder block 10 can be made one with bearing support 9, also independent is fixed on the bearing support 9 then, piston 21 is arranged in the cylinder block 10, piston is loaded on the bar 18 and (for example uses nut 22 or additive method), one end of bar 18 is pressed on the cam of cam cover 7 by the elastic force of spring 19, the 20th, the lid of holddown spring 19, the top of piston 21 has valve body 23 and valve gap 25, have suction valve disc 24 on the valve body 23 and discharge valve block 28, suction port 26 is arranged on the valve gap 25, it links to each other with the exhaust port of pump spiral case 14 by pipe 11, also have exhaust port 27 on the valve gap 25, exhaust port 27 communicates with atmosphere by managing 12, also has lock screw 29 on the cylinder block 10, it is in order to make piston 21 be parked in upper dead center after the pump starting, to reduce power consumption and wearing and tearing.

Clutch 5 is positioned on the main shaft 2 of powered pulley 6 sides, and available handle 4 is handled, and has link stopper 1 on main shaft 2, and it makes the pressure of spring 3 push away clutch and can oneself disengagement when clutch is combined with belt pulley.When starting, need the then available hand of the throw-out-of clutch position handle 4 of stopping.Clutch 5 can be to move axially spline or flat key with cooperating of axle.

Fig. 3 shows second kind of embodiment (main shaft portion) of the utility model self-sucking energy-saving water pump, be the direct-connected embodiment of pump and motor, be with a shaft coupling 31 on the motor shaft 30, shaft coupling 31 links to each other with cam cover 7 by flange 32, the other end of cam cover 7 is that an end of cam side has junction plane, it can combine with the clutch 5 on axle 2, clutch 5 slides on axle 2, the opposite side of clutch has spring 3, the other end of spring 3 is then fixing by cartridge housing 9, when clutch 5 combined with the cam cover, spring 3 can not thrown off them automatically.

On the cam cover 7 eccentric weight of balancer weight with equilibrium cam should be arranged.

The programmed sequence of operations of self-sucking energy-saving water pump is also very simple, should have an ad hoc pipeline 15 and one-way valve 16 on the exhaust port of pump when pump directly pumps up water for irrigation, it can be direct-connected with the exhaust port of pump, when pump discharge also has waterline, then can be as the bypass of pipeline, but also valve need be arranged on the pipeline, deflate so that when starting, close, during starting, earlier clutch 5 and belt pulley 6 or cam cover 7 are thrown off, starting power engine (motor or internal-combustion engine) rotates cam cover 7, (this moment, main shaft 2 did not change), this moment, piston 21 was by the cam driven move left and right, by managing 11 with spiral case shell and suction line, the air in the discharge tube before the one-way valve sucks cylinder 10 and enters atmosphere through expulsion valve 28 and discharge tube 12, and liquid level rises gradually, make when then moving handle 4 during discharge water in the discharge tube clutch 5 in conjunction with and make main shaft 2 rotations, this moment can be by pump drainage.But the valve of operating pumps outlet and make it proper functioning then, and lock screw 29 is screwed into and makes piston stop going up motion.Also can be belt pulley on the cam cover (7), drive piston 21 by the general kind of drive, and finish air-breathing work.

Certainly, motive power wheel (belt pulley 6 or flange plate 32) can be direct-connected with main shaft, rotate and drive cam cover 7 by clutch, its structure is to be connected with powered pulley 6 or flange plate 32 in the end of main shaft 2, have clutch 5 on the axle 2 between belt pulley (6) or flange plate 32 and the cam cover, the clutch 5 that closes can make the cam cover rotate, and declutch, then the cam cover does not rotate.This moment is when starting, the clutch 5 that closes earlier, and after the priming pump water outlet, declutch again.

Self-sucking energy-saving water pump of the present utility model, needn't pour water starting and use bottom valve, work convenient and time-saving laborsaving, can in very short time, start, as a 4BA13A water pump, inhale under the high situation at 4-6 rice, the water outlet of can in one minute, finding time, simple in structure, cost is low, save bottom valve, pump performance is improved, reach self-priming, purpose of energy saving.
