Abstract
The utility model relates to a full-seal corrosion resisting pump. An annular plastic spacer sleeve is arranged in the interior of a pump body in order to prevent liquid which is transported from leaking from the position of a pump shaft, and the pump shaft and the liquid are separated. The full-seal corrosion resisting pump not only can prevent leakage, but also can solve the air-corrosion problem of the pump shaft and a liquid wheel. The full-seal corrosion resisting pump has strong self-suction capability. Before the full-seal corrosion resisting pump is used, suction water is not needed to be poured. The full-seal corrosion resisting pump can be used for the industries of petroleum and chemical fertilizer, electroplating, foodstuffs and beverage, etc.
Description
The utility model belongs to liquid capacity-changing mechanical
Requirement for the corrosion free pump of carrying corrosive liquids is:
One, energy self-priming, it is easy to use to start shooting, without water;
Two, withstand corrosion, the corrosion of promptly all kinds of acid, alkali, salt solution;
Three, do not have leakage, do not have cavitation erosion;
Four, reliable performance, cost are low, easy to maintenance.
But the corrosion free pump that prior art provided can not satisfy above condition fully, as, existing centrifugal corrosion free pump, pump shaft, hydraulic fluid wheel rotate in the solution of being carried, no matter adopt the sealing of rubber ring or asbestos packing, still adopt the mechanical sealing of dynamic and static ring assembly, the liquid of being carried all can leak from pump shaft.Special when containing the granular mechanical admixture in the solution, pump shaft, the hydraulic fluid wheel damages and is exceedingly fast.And must make full of liquid in the pump when using, the emptying air, otherwise will cavitate.
The purpose of this utility model is to be to make a kind of energy self-priming, nothing leakage, does not have cavitation erosion, the whole-sealed corrosion-resistant pump that cost is low.
Technological points of the present utility model is to adopt the annular plasticity spacer and the pump housing to form a hermetic sap cavity, the hydraulic fluid wheel is separated with the pump housing, the liquid of being carried can only be flowed in hermetically sealed sap cavity, solved the sealing of corrosion free pump, the damage problem of pump shaft and hydraulic fluid wheel.
The utility model has figure
Fig. 1 is the whole-sealed corrosion-resistant pump schematic representation
Fig. 2 is a whole-sealed corrosion-resistant pump A-A sectional drawing
As an embodiment of the present utility model as shown in the figure.
Whole-sealed corrosion-resistant pump provided by the utility model, the pump housing (3) that a liquid entering hole (1) and liquid outlet (2) are arranged, an annular boss (4) is arranged on the pump housing, a groove (5) is arranged on annular boss, its position is between liquid entering hole and liquid outlet, an annular plasticity spacer (6), on the annular plasticity spacer all U-groove bevels (14) and liquid islocation plate (15) are arranged, the annular plasticity spacer and the pump housing are combined to form a hermetically sealed sap cavity (7), the outside of annular plasticity spacer has pump shaft (8) to take turns (9) and be connected support (10) with hydraulic fluid, end cap (11) is arranged before and after the pump housing, boss (12) is arranged on the end cap, the pump housing, annular plasticity spacer, front and rear cover is linked together by screw (13).Having a liquid islocation plate (15) that matches with pump housing groove (5) its objective is on the annular plasticity spacer separates liquid entering hole and liquid outlet.Annular plasticity spacer can be according to the different chemical character of conveying liquid, different corrosivity apolegamy different materials are made, and the hydraulic fluid wheel is to be linked together by support and pump shaft, rotate with pump shaft and oppress annular plasticity spacer, just its distortion is restored and change sap cavity volume.Infusion process reaches by changing the sap cavity volume.
Annular plasticity spacer can be made with nontoxic rubber when using in food_beverage industry.
The spacer that when oils liquid is carried, preferably uses oil resistant rubber to make.
To acid, alkali, the conveying of salt class I liquid I the time, spacer preferably selects acid and alkali resistance, salt rubber to make.
