Description
Technical field
The utility model relates to a kind of sand pump inner bag, belongs to mechanical fitting technical field.
Background technique
Its pump case of existing sand pump mostly is cast iron and casts, and this sand pump life-span is low, and general pump case working life is at about 2 ~ 30,000 cubes.The sand holes of also being cast by cast iron due to pump case are more, easily leak, and also affect sand pump casing working life.Also there is the danger of " fried shell " in using process, cause operator to there is potential safety hazard.And the great sand pump casing of this use amount, not only fabricating cost is high, and also there is a lot of environmentally hazardous factor in manufacture process.Therefore, extremely need one not only environmental protection but also safety, and the device that fabricating cost is low, improve the working life of sand pump.
Summary of the invention
In order to solve the deficiency that above-mentioned prior art exists, the utility model provides a kind of sand pump inner bag, and this sand pump inner bag protects whole pump case, prevents " fried shell ", improves 2 ~ 3 times of pump case working life, and replaceable.
The utility model solves the technological scheme that its technical problem adopts: a kind of sand pump inner bag, its structure is: be equipped with cavity in sand pump casing, the feed-water end flange plate matched with sand pump casing is provided with above cavity, the power end flange plate matched with sand pump casing is provided with below cavity, cavity front end is provided with the waterexit end flange plate matched with sand pump casing, and wherein chamber outer wall is close to the inwall of whole sand pump casing.Power end flange plate on cavity, waterexit end flange plate and feed-water end flange plate are separately positioned on outside the flange plate on sand pump casing, and the flange plate being connected outer end by sand pump casing is fixedly clamped; Whole cavity is synthetic rubber material.
The beneficial effects of the utility model are: it is low that the utility model solves the sand pump casing life-span; on the pump case cast sand holes more, easily to leak, easily " fried shell "; affect the problems such as sand pump casing working life; protection operator safety; improve 2 ~ 3 times of pump case working life; replaceable, reduce the cost repeatedly buying pump case, indirectly protect environment.
