A kind of critical piece effect of single-suction slurry pump of the present invention is as follows respectively：
First oil sealing 20 and the second oil sealing 21 for realizing the main shaft 11 of rotation sealing, due to the first oil sealing 20 and second
There is the oil films of two oil sealing cutting edges control between oil sealing 21 and main shaft 11, this oil film has fluid lubrication characteristic, in oil body table
Under the action of the tension of face, the rigidity of oil film makes oil film form a new lunar surface with air contact jaw just, it is therefore prevented that working media
Leakage.
Cooling down component solves the problems, such as the cooling down of main shaft 11, the horizontal direct-connected mortar pump work of single suction of the invention
Before, oily window cover 29 need to be first passed through toward pouring into cooling oil in oily window 28, when work, the heat of main shaft will pass to cooling oil,
To make cooling oil temperature increase, at this point, external coolant liquid flows into cooling tube 30 from connector 32, cooling tube 30 will and cooling oil
Temperature difference is generated, cooling oil temperature will be further reduced, to achieve the purpose that cooling main shaft 11.
The sealing for acting as realizing main shaft 11 of seal assembly, since 11 surface of main shaft is in the case that microcosmic very uneven
It is whole, it can only be partly bonded with oil immersion asbestos packing 41, so there are small gap between oil immersion asbestos packing 41 and main shaft 11,
Just as labyrinth, by the way that the sealing structures such as filler baffle ring 40, packing ring 42 and stuffing box 44 are arranged, make working media in labyrinth
Repeatedly shut off, to reach good sealing function.
Shaft coupling 12 is for linking together main shaft 11 and motor shaft.
A kind of course of work of single-suction slurry pump of the present invention is specific as follows：
Before a kind of single-suction mortar pump startup of the present invention, transported grey slurries are filled into pump case 6 by inlet tube 4
Shaft coupling 12 is connect by body with motor, and motor delivers torque to main shaft 11 by shaft coupling 12, to 8 high speed of impeller
Rotation, mortar liquid also rotate therewith, and under the influence of centrifugal force, mortar liquid is thrown to outer rim from 8 center of impeller and obtained
Energy enters pump case 6 to leave 8 outer rim of impeller at a high speed, and in pump case 6, mortar liquid slows down due to being gradually expanded for runner,
Part kinetic energy is changed into static energy again, finally with higher pressure current inlet/outlet pipe 5, is sent to needing place.Liquid is by impeller 8
When center flows to outer rim, certain vacuum is centrally formed in impeller 8, since the pressure at 8 center of impeller is less than at pump intake
Pressure, liquid are just continuously pressed into impeller 8, and impeller 8 constantly rotates, and liquid constantly will be inhaled into and be discharged, to reach
To the purpose of work.
By the above-mentioned means, a kind of this slurry pump of single-suction slurry pump of the invention is simple in structure, safe and reliable；Purposes
Extensively, it is not required to diversion, is easy to start, power is big, and lift maximum is up to 47m；Overcurrent part wearing piece is hot investment casting part, is not required to
Machining is conducive to select high-hardness in this way, substantially prolongs a kind of use of this slurry pump of single-suction slurry pump of the invention
Service life；The impeller 8 of the present invention uses backward bent vane double shrouded wheel, is lost without the undercurrent of blade to top, and efficiency is higher, because
This reduces energy loss, greatly improves working efficiency under the premise of guaranteeing to convey mortar；Compared to gear, belt wheel
Connection type, the present invention in shaft coupling 12 reduce energy loss, improve transmission efficiency；The present invention has cooling down group
Part can effectively reduce 11 temperature of main shaft, be allowed to adapt to worse working environment；It is set between stuffing box 44 and axle sleeve 37
It is equipped with oil immersion asbestos packing 41, not only acts as sealing function, also there is good rebound, good lubricity, better corrosion resistant
Corrosion further extends the service life of the present invention.
