Abstract
The utility model relates to a slurry conveying pump which is composed of a driving mechanism and a pump body. The utility model is characterized in that a diaphragm can make a piston of a piston pump separated from a cylinder, so that the utility model can produce the variation of the volume and can produce the high pressure to realize the conveying operation of the fluid and the semifluid; the utility model can not produce the relative slide friction and the pollution. The pump is suitable for pumping the wet grout, the slurry, various chemical solutions, the food pulp, the sewage mud. The pump has the advantages of simple structure, convenient manufacture, low required precision, easy repair, and low cost. The utility model can not easily be damaged and the utility model is an ideal slurry conveying pump.
Description
The utility model relates to a kind of pump, particularly a kind of pump of carrying slurries.
Present slurries transfer pump mostly is to adopt piston back and forth to aspirate, and this pump piston and cylinder body are made complicated, the precision prescribed height, in use very easily wearing and tearing again cause slurries to leak, service behaviour instability and befouling environment cause the cost of production maintenance cost to rise.
Task of the present utility model is to design a kind of do not have wearing and tearing, nothing leakage and slurries transfer pump easy to maintenance, in order to overcome the deficiency of existing slurries transfer pump.
Task of the present utility model can realize by following proposal:
The utility model is made up of driving mechanism and the pump housing two parts, and drive wheel, ratio wheel, crankshaft and piston bar are arranged on the driving mechanism, and driving mechanism has casing outward, and motor or diesel engine are housed above the casing, and footing is arranged below, and there is the pump housing in the left side.The slurries inlet is arranged on the pump housing, feed liquor list internal valve, barrier film, piston, cylinder body, output slurries one-way valve and slurries outlet, the barrier film outer is contained between casing and the cylinder body, casing is fitted together by left side and piston (4) external diameter circular hole of a size and cylinder body, and the cylinder body corresponding positions is equipped with corresponding circular hole.Be characterized in that ring is installed on the piston in the barrier film, the outer is installed on the shell between cylinder body and the casing, and its material is the promptly old inferior peace of polyoxymethylene, PPO PPO modification or polyimide PI.
The utility model has the advantages that the cylinder-piston suction that changes the slurries transfer pump is for to aspirate every the membrane bowl type piston, thereby simple in structure, easy to make, precision prescribed is low, not fragile, repair easily, cost is low, is applicable to the mortar conveying, slurry transportation, various chemical liquids will be carried, and the food slurries are carried and the sewage sludge suction, are a kind of desirable slurries transfer pumps.
Below in conjunction with accompanying drawing the utility model is done detailed description further.
Fig. 1 is an overall structure partial sectional view of the present utility model.
As Fig. 1, drive wheel, ratio wheel, bent axle (9) and piston rod (8) are arranged on the driving mechanism, driving mechanism has casing (11) outward, and motor or diesel engine (10) are housed above the casing (11), and footing is arranged below, and there is the pump housing in the left side.Slurries inlet (1), feed liquor one-way valve (2), barrier film (3), piston (4), cylinder body (5), output slurries one-way valves (6) and slurries outlets (7) are arranged on the pump housing, barrier film (3) outer is contained between casing (11) and the cylinder body (5), and casing (11) is fitted together through barrier film (3) and cylinder body (5) by left side and piston external diameter circular hole of a size.Be characterized in that ring is installed on the piston (4) in the barrier film (3), the outer is installed on the shell between cylinder body (4) and the casing (11).
The working principle of this pump is: motor or diesel engine (10) are done power and are driven drive wheel by the vee belt, drive wheel drives ratio wheel, ratio wheel drives piston rod (8), piston (4) and barrier film by the bent axle on it (9) and moves reciprocatingly, realize the volume-variation of pump, thereby realize the output of slurries.After the piston (4) of pump moves to the summit of volume minimum, because the motion of bent axle (9), when piston (4) and the interior hoop left of barrier film (3) are the motion of volume maximum point, volume strengthens gradually, the interior generation of pump negative pressure is then exported slurries one-way valve (6) and is closed, feed liquor one-way valve (2) is opened, in the slurries inflow pump that aspirate; Diminish when being the left-hand motion to volume when bent axle (9) drives piston (4) and barrier film (3), produce malleation in the pump, then feed liquor valve (2) cuts out, and liquid valve (6) is opened the output of finishing pump.Feed liquor one-way valve (2) and fluid one-way valve (6) are and are covered with a semi-round ball cross reinforcing bar on the ball admittedly.
Claims (3)
1, a kind of slurries transfer pump, form by driving mechanism and the pump housing two parts, drive wheel is arranged on the driving mechanism, ratio wheel, bent axle (9) and piston rod (8), driving mechanism has casing (11) outward, motor or diesel engine (10) are housed above the casing (11), footing is arranged below, there is the pump housing in the left side, it is characterized in that having on the pump housing slurries inlets (1), feed liquor one-way valve (2), barrier film (3), piston (4), cylinder body (5), output slurries one-way valves (6) and slurries outlets (7), barrier film (3) outer is contained between casing (11) and the cylinder body (5), casing (11) is fitted together by left side and piston (4) external diameter circular hole of a size and cylinder body (5), and cylinder body (5) corresponding positions is equipped with corresponding circle hole.
2, transfer pump according to claim 1 is characterized in that ring is installed on the piston (4) in the barrier film (3), and the outer is installed between cylinder body (5) and the casing (11).
3, transfer pump according to claim 1, the material that it is characterized in that barrier film (3) are that polyoxymethylene, PPO PPO modification or polyimide PI are old imines.
