Abstract
The utility model discloses a large-flow magnesium alloy liquid transferring pump, which belongs to the technical field of magnesium alloy equipment, can be used in magnesium liquid transferring and quantitative casting in the large-flow magnesium alloy preparation engineering required for high lift, and solves the problems that the conventional liquid transfer pump has low flow, low lift, can not be used in the high-lift magnesium alloy smelt engineering, and has short service life. The large-flow magnesium alloy liquid transferring pump is characterized by including a blade, a pump body, a discharge pipe, a feed opening baffle connected with the pump body, a pump shaft, a coupling, a main reinforcing sleeve, an upper bearing seat, a middle bearing seat and a lower bearing seat, wherein the liquid transferring pump is driven by a motor, and is connected to the pump shaft through the coupling; the pump shaft is connected with the blade and fixed through the upper, the middle and the lower bearing seats; a matching clearance C and a matching clearance D are arranged between the blade and the pump body; the size of the clearance C is 25mm to 35mm, and the size of the clearance D is 1mm to 2mm. Through adopting the scheme, the benefits that the flow of the liquid transferring pump is increased, the lift of the liquid transferring pump is improved, and the service life of the liquid transferring pump is prolonged are achieved.
Description
Technical field
The utility model belongs to the magnesium alloy equipment technical field, more specifically says to relate to the big flow magnesium alloy commentaries on classics liquid pump that a kind of magnesium liquid that can be used for high-lift, the big flow magnesium alloy of requirement preparation engineering changes liquid and quantitative casting.
Background technique
The existing blade that changes liquid pump is that concentric type cooperates with the pump housing, and the gap, both sides equates that centrifugal force changes with change in rotational speed; When the big flow of needs, when high-lift magnesium liquid transmits; The centrifugal force that motor produces under the maximum speed that allows can not reach corresponding lift, and in use, flow is low; Lift is low, and it is very short to be used for high-lift magnesium alloy smelting engineering and working life.
Summary of the invention
The purpose of the utility model is: provide a kind of big flow magnesium alloy to change liquid pump, exist flow low to solve the existing liquid pump that changes, lift is low, can not be used for high-lift magnesium alloy smelt engineering and working life short problem.
The technological scheme that the utility model is taked is: a kind of big flow magnesium alloy changes liquid pump, it is characterized in that: comprise blade, the pump housing, discharge nozzle, the material feeding mouth baffle plate that is connected with the pump housing; Pump shaft, coupling, main sleeve, upper bearing bracket, bottom bracket, the step strengthened changes liquid pump by motor driving; Be connected to pump shaft through coupling, pump shaft is connected with blade, and pump shaft is fixed by upper bearing bracket, bottom bracket and step; Be provided with coupling clearance C and clearance D between the blade and the pump housing; The size of clearance C is between 25-35mm, and the size of clearance D reaches the purpose of big flow with the loss amount that reduces to get into pump housing magnesium liquid between 1-2mm.
The utility model changes existing blade and pump housing matching part into eccentric by existing center type, makes in the process of blade rotation at drive motor, and the blade rotation produces centrifugal force; Magnesium gets into pump chamber through the pump housing inlet night; The rotation of vane drive magnesium liquid because the magnesium liquid major part that the pump housing is made in the eccentric entering pump chamber gets into discharge nozzle through discharge port, has only fraction by losing in the space between the blade and the pump housing; Thereby reduced the loss of magnesium liquid, improved the efficient of pump greatly.Thereby the flow that changes liquid pump is increased greatly, therefore can reduce the rotating speed that changes liquid pump, and improve the lift that changes liquid pump, prolonging changes the life-span that liquid pump uses.
The beneficial effect that the utility model reaches is: adopt this programme, reached the flow that increases the commentaries on classics liquid pump, the beneficial effect that improves the lift that changes liquid pump and prolong the life-span of changeing the liquid pump use.

Embodiment
Illustrate further the structure characteristic of the utility model below in conjunction with accompanying drawing.
With reference to Fig. 1,2, big flow magnesium alloy changes liquid pump, it is characterized in that: comprise blade 1, the pump housing 2, discharge nozzle 3; The material feeding mouth baffle plate 4 that is connected with the pump housing 2, pump shaft 9, coupling 6, main sleeve 11, upper bearing bracket 7, bottom bracket 8, the step 10 strengthened; Change liquid pump and driven by motor 5, be connected to pump shaft 9 through coupling 6, pump shaft 9 is connected with blade 1; Pump shaft 9 is fixing by upper bearing bracket 7, bottom bracket 8 and step 10; Be provided with coupling clearance C 12 and clearance D 13 between the blade 1 and the pump housing 2, the size of clearance C 12 is between 25-35mm, and the size of clearance D 13 is between 1-2mm.Equate by existing clearance C 12, clearance D 13, change clearance C 12 into, reach the purpose of big flow with the loss amount that reduces to get into the pump housing 2 magnesium liquid greater than clearance D 13.Motor 5 drives pump shaft 9 and rotates, and guarantees operating steadily of pump through upper bearing bracket 7, bottom bracket 8 and step 10.Blade 1 adopts eccentric to cooperate with the pump housing 2, and magnesium liquid flows out through discharge nozzle 3.Adopt this programme, with existing pump under the working state of equal rotating speed time, flow be the existing pump flow 2-3 doubly, and lift is more than 2 times of existing pump.
