A kind of critical piece effect of direct-connected horizontal 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 direct-connected horizontal slurry pump of the present invention is specific as follows:
Before the direct-connected horizontal mortar pump startup of one kind of the invention, transported mortar is filled into pump case 6 by inlet tube 4 Shaft coupling 12 is connect by liquid with motor, and motor delivers torque to main shaft 11 by shaft coupling 12, to which impeller 8 is high Speed 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 is obtained, enters pump case 6 to leave 8 outer rim of impeller at a high speed, in pump case 6, mortar liquid subtracts due to being gradually expanded for runner Speed, and part kinetic energy is changed into static energy is sent finally with higher pressure current inlet/outlet pipe 5 to needing place.Liquid is by leaf When taking turns 8 centers and flowing 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 just by continuously be pressed into impeller 8 in, impeller 8 constantly rotates, and liquid constantly will be inhaled into and be discharged, with Achieve the purpose that work.
By the above-mentioned means, a kind of direct-connected horizontal this slurry pump of slurry pump of the present invention is simple in structure, safe and reliable;With Way extensively, 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, no It needs to machine, is conducive to select high-hardness in this way, substantially prolong a kind of direct-connected horizontal this slurry pump of slurry pump of the present invention Service life;The present invention impeller 8 use backward bent vane double shrouded wheel, without blade to top undercurrent loss, efficiency compared with Therefore height under the premise of guaranteeing to convey mortar, reduces energy loss, greatly improves working efficiency;Compared to tooth It takes turns, belt wheel connection type, the shaft coupling 12 in the present invention reduces energy loss, improves transmission efficiency;The present invention has drop Warm cooling component can effectively reduce 11 temperature of main shaft, be allowed to adapt to worse working environment;Stuffing box 44 and axle sleeve Be provided with oil immersion asbestos packing 41 between 37, not only act as sealing function, also have good rebound, good lubricity, more Good corrosion resistance further extends the service life of the present invention.
