Abstract
The utility model relates to a high-temperature sulfuric acid pump, and in particular to a centrifugal pump which is used for conveying a high-temperature strong-corrosion acid medium, which mainly aims at solving the problems that of the prior centrifugal pump for conveying the high-temperature strong-corrosion acid medium that the sealing effect is poor and the hot impact and the mechanical impact always lead to the damage, and comprises a pump body, wherein the pump body is provided with a pump suction inlet and a pump outlet, an impeller is arranged inside the pump body, the impeller is installed on a pump shaft, the pump shaft is installed on a bearing bracket through a bearing, the bearing bracket is fixed on a pump block through a suspension bracket, the pump shaft is connected witha motor through a coupler, the pump body, an isolation plate and a stuffing box are split from the back surface of the impeller, stuffing is arranged inside the stuffing box, the impeller adopts a structure of a front and a rear flow passages, an auxiliary impeller is arranged behind the isolation plate inside the pump body, and the auxiliary impeller is installed on the pump shaft; and a protection shell is installed outside the pump body, stuffing is arranged between the protection shell and the pump body, and the protection shell is fixed on the pump block. The high-temperature sulfuric acid pump has the advantages that the sealing effect is good; in addition, the protection shell is arranged outside the pump body, so that the protection shell can protect the pump body, and the servicelife of the pump can be prolonged.
Description
Technical field:
The utility model relates to a kind of centrifugal pump of carrying the high temperature strong corrosion acid medium.
Background technique:
The centrifugal pump sealing effect of existing conveying high temperature strong corrosion acid medium is poor, and sour sometimes leakage can cause environmental pollution and influence production safety; Make (being commonly called as metglass) because this centrifugal pump is many by high silicon cast iron again, often cause damage, thereby shorten the working life of pump because of thermal shock and mechanical shock.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of good sealing effect, and heat shock resistance and mechanical shock ability are strong, the high temperature sulfuric acid pump of long service life.
Above-mentioned purpose is achieved in that it comprises the pump housing, Pump Suction Nozzle and pump discharge are arranged on the pump housing, impeller is arranged in the pump housing, impeller is contained on the pump shaft, pump shaft is contained on the bearing bracket stand by bearing, bearing bracket stand is fixed on the pump seat by suspension strut, pump shaft is connected with motor by coupling, the pump housing, dividing plate and Stuffing box are from impeller back side subdivision, filler is arranged in the Stuffing box, and the pump housing, dividing plate and Stuffing box constitute the working room of pump, unlike the prior art be that impeller adopts forward and backward double flow channel structure, at the pump housing internal partition rear sub-propeller is arranged, sub-propeller is contained on the pump shaft; Protective case is housed outside the pump housing, between the protective case and the pump housing filler is housed, protective case is fixed on the pump seat, plays protection and supporting effect.
The utility model has the advantages that because impeller adopts forward and backward double flow channel structure sub-propeller is arranged, when pump work, can play the motive sealing effect,, help production safety and environmental protection so good sealing effect can prevent the acid leakage to liquid at pump housing internal partition rear; Because protective case is housed outside the pump housing, filler is housed again between the protective case and the pump housing, the pump housing is played a protective role, thus the working life of prolongation pump.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
