Description
Technical field
The utility model relates to a kind of centrifugal pump.
Background technique
Existing centrifugal pump comprises base, the pump housing, impeller and motor, and the described pump housing and motor are located on base, and described motor is provided with main shaft, and described impeller to be arranged in the pump housing and to be connected with one end of main shaft, and described main shaft is provided with mechanical seal device.Existing centrifugal pump has the following disadvantages: one is because the weight of the pump housing is large, mobile very inconvenient; Two is that existing mechanical seal device easily produces leakage problem, affects environment; Three is existing centrifugal pump impeller structure not science, easily wear phenomenon occurring, affecting its working life when carrying containing during solid medium.
Model utility content
The purpose of this utility model provides a kind of long service life for above-mentioned situation exactly, leakage phenomenon can not occur and be convenient to the centrifugal pump of movement.The purpose of this utility model realizes by following scheme: a kind of moveable centrifugal pump, comprise base, the pump housing, impeller and motor, the described pump housing and motor are located on base, described motor is provided with main shaft, and described impeller to be arranged in the pump housing and to be connected with one end of main shaft, and described main shaft is provided with mechanical seal device, it is characterized in that described base bottom both sides are provided with movable pulley, be convenient to mobile, base right-hand member upper vertical welds a hand push-rod, is convenient to by hand propulsion, described mechanical seal device comprises axle sleeve, machine envelope stationary ring and machine envelope rotating ring is connected in the outer cover of axle sleeve, form friction pair, machine envelope stationary seat is connected at machine envelope stationary ring and machine envelope rotating ring outer cover, machine envelope stationary seat one end is provided with machine envelope washing solution entrance, described machine envelope washing solution ingress is provided with throttle, machine envelope stationary seat seals the relative one end of washing solution entrance to be provided with machine and to seal washing solution with machine and export, the outlet of machine envelope washing solution is connected to pump housing ingress by reflux pipeline, machine envelope rotating ring seals rotating seat by 6-8 flexible compensation springs and machine and is connected, machine envelope rotating seat is socketed in axle sleeve outside, the utility model mechanical seal rinsing liquid is ingress engine envelope washing solution entrance after throttle throttling, dynamic from machine envelope washing solution entrance ingress engine envelope, the friction pair chamber that stationary ring is formed, for friction pair plays cooling, lubrication, the machine envelope washing solution outlet that machine envelope stationary seat opposite side is arranged can make mechanical seal reflux liquid introduce the entrance of the pump housing from here through reflux pipeline, because pump housing entrance is negative pressure, easy realization backflow, ensure that mechanical seal is not because causing mechanical seal leakage when negative pressure pump shaft vibration causes friction pair to depart from, described impeller comprises blade, wheel hub, front shroud, front shroud back blades, back shroud and back shroud back blades, the cross section of described front shroud back blades is the first right-angled trapezium, the hypotenuse of described first right-angled trapezium is positioned at the back side of described front shroud back blades, the cross section of described back shroud back blades is the second right-angled trapezium, the hypotenuse of described second right-angled trapezium is positioned at the back side of back shroud back blades, the quantity of described front shroud back blades quantity and described back shroud back blades is all 24, described front shroud back blades is backward leaning vane, its length is equal, described back shroud back blades is backward leaning vane, described back shroud back blades comprises three groups of back blades, and the length of three groups of back blades is different, due to the quantity of described front shroud back blades and described back shroud back blades is increased greatly, thus decrease containing solid medium from impeller outlet to the leakage rate in impeller inlet direction, reduce containing the wearing and tearing of solid medium to front shroud and back shroud, in addition, due to the setting of hypotenuse in front shroud back blades and back shroud back blades, when MEDIA FLOW is to the back side of described front shroud back blades and described back shroud back blades, the change flowed to is little, therefore, it is possible to stop the generation of whirlpool, thus reduce containing the wearing and tearing of solid medium to described front shroud and described back shroud.The utility model has long service life, leakage phenomenon can not occur and be convenient to the features such as mobile.
