Description
Technical field:
The utility model belongs to pump type seal technical field, relates to a kind of liquor pump cyclic sealing gasket, particularly one and is provided with multi-sealed line structure, can reduce gas-liquid and leak, effectively improve the cyclic sealing gasket of lift value.
Background technique:
Liquor pump is the device of the energy mechanical energy of prime mover being converted to flow of fluid; Liquor pump before activation, first in pump case, fill the liquid be transferred, after startup, prime mover rotarily drives liquid pump and rotates, liquid pump impeller High Rotation Speed, and impeller drives interlobate liquid to rotate simultaneously, liquid is thrown to impeller outer edge from impeller central under the influence of centrifugal force and is obtained energy, and so that leaving impeller outer edge enters volute pump case at a high speed, liquid flows into discharge conduit with higher pressure, is transported to height and the place of needs; When liquid flows to outer rim by impeller central, define certain vacuum in impeller central, the pressure due to storage tank ullage is greater than the pressure of liquor pump ingress, and liquid is just pressed in impeller continuously; Therefore, if the connection part of liquor pump ingress has gas-liquid leakage phenomenon, so the degree of vacuum at pump intake place reduces, reduce liquor pump external and internal pressure poor, shorten the lift (lift is that the unit weight liquid pumped of pump is from pump housing inlet to the increment of pump housing outlet port energy) of liquid, result liquid just can not be transported to the place of needs.In the prior art, be directly connected and fixed between the liquid inlet place end face of liquor pump and liquid input tube road end face by bolt, the contact in face and face makes sealing effect not good, causes gas leakage and reduces pull of vacuum, thus reducing the lift of liquid; Therefore, seek to design a kind of liquor pump cyclic sealing gasket very with practical value, be arranged between the liquid inlet of liquor pump and liquid input tube road, ensured that liquid inlet is with between sealing gasket and efficient sealedly between sealing gasket with liquid input tube road to be connected, and reduces gas-liquid and leaks respectively, sealing gasket is arranged circular seal line, the tightness of the further increase pump housing, improve pump housing work lift and working efficiency, the structural design of sealing gasket is simply ingenious, easy for installation, be convenient to batch production.
Summary of the invention:
Goal of the invention of the present utility model is the shortcoming overcoming prior art existence, a kind of liquor pump cyclic sealing gasket of design is proposed, not good with the joint sealing solving existing liquor pump entrance and liquid input tube road, gas-liquid is leaked and is caused lift to shorten, the problem that useful work reduces, the sealing of effective reinforcement pump liquid pump intake joint, improves output power, increases lift value.
In order to realize foregoing invention object, the agent structure of the liquor pump cyclic sealing gasket that the utility model relates to comprises sealing gasket base, cylinder, boss, bolt passing hole, the first inner ring seal line, the second inner ring seal line, the first outer ring seal line, the second outer ring seal line, cylindrical and inner circle, the thickness of the sealing gasket base of circular plane structure is 2-5mm, the outside diameter of sealing gasket base is 1-3 times of interior circular diameter, the inner circle edge of sealing gasket base has integrated thickness to be the cylinder perpendicular to sealing gasket base of 2-5mm, the internal diameter of cylinder is identical with the interior diameter of a circle of sealing gasket base, and cylinder heights is 10-50mm, one end near sealing gasket base on cylinder is provided with the integrated boss around cylinder border, and the height of boss is 1/7 of cylinder heights, and thickness is 1/3 of boss height, sealing gasket base evenly offers the identical bolt passing hole of 4 diameters on the position of cylindrical, sealing gasket base upper surface is provided with the first inner ring seal line and the second inner ring seal line of the convex concentric with cylinder, spacing between first inner ring seal line and boss external diameter is more than or equal to the spacing between the first inner ring seal line and the second inner ring seal line, sealing gasket base lower surface is provided with the first outer ring seal line and the second outer ring seal line of the convex concentric with annulus, first outer ring seal line is identical with the first inner ring seal linear diameter, second outer ring seal line is identical with the second inner ring seal linear diameter, first inner ring seal line, second inner ring seal line, first outer ring seal line and the second outer ring seal line are the identical triangular hill structure of cross-sectional structure.
The utility model compared with prior art, adopt the sealing gasket of plastic body, increase the tightness of liquor pump inlet connection, the top and bottom of sealing gasket disk all arrange potted line structure, realize impeller be connected with intake pipe between close contact, effectively improve sealing effect; Its simple and ingenious structure, materials are scientific and reasonable, and preparation cost is low, use good energy-conserving effect, are convenient to batch production, and applied environment is friendly.
