Abstract
A chemical centrifugal pump comprises a mechanical seal stationary ring, a stationary ring holder and a mechanical seal spring. A sealed cavity formed by a pump body and a pump cover is provided with an impeller arranged on the left portion of a shaft. The top portion of the impeller is tightly locked by an impeller nut. A groove on the right portion of the impeller is provided with a mechanical seal moving ring. A shaft sleeve, the mechanical seal spring and a sealed box are successively sleeved on the shaft from inside to outside, wherein the shaft is disposed at the connecting portion between the bump cover and a bracket. The stationary ring holder is sleeved on the left inside the sealed box. The stationary ring holder is provided with a spring holder. The mechanical seal stationary ring is arranged on the left portion of the spring holder. A bearing set is disposed on the shaft inside the inner cavity on the right portion of the bracket. A grease nozzle is arranged above the bearing set. The chemical centrifugal pump of the utility model provides an advanced sealing technique, is suitable for conveying materials having solid contents less than 35%, and exhibits a sealing effect of three to five times higher than a conventional chemical pump. The impeller is designed to be an open type structure. Therefore, the chemical centrifugal pump serves as an advanced and the most desirable device for conveying various materials in the chemical industry.
Description
Technical field: the utility model relates to a kind of chemical centrifugal pump.It is the optimal sophisticated equipment that chemical industry is carried various materials.
Background technique: traditional chemical pump can only be carried the medium of physical property similar water, the seal arrangement weak effect, and the phenomenon of " drip, run, emit, leak " can not be effected a radical cure, not only reduced manufacturing efficiency, befouling environment, and working life is short, so the utilization scope is restricted.
Summary of the invention: the purpose of this utility model will provide a kind of chemical centrifugal pump exactly, and it can overcome the existing problem of above traditional chemical pump.The purpose of this utility model is to realize like this, chemical centrifugal pump, comprise that mechanical sealing static ring, stationary seat, mechanical seal spring form, it is characterized in that: be provided with the impeller of device in the Seal cage that the pump housing and pump cover form at the axle left end, the top of impeller is locked by impeller nut, is provided with mechanical sealing linkage ring in the right-hand member groove of impeller; On the axle of pump cover and carriage connection place, outwards be with axle sleeve, mechanical seal spring, sealed case successively from the lining; The left side in the described sealed case is with stationary seat, is provided with spring seat in the stationary seat, and the left end of spring seat is provided with mechanical sealing static ring, and the bottom righthand side of sealed case is provided with water nozzle; Axle in the right-hand member inner chamber of described carriage is provided with bearing pack, and the top of bearing pack is provided with grease nipple, and the right-hand member below of carriage is provided with outstanding support.The utility model sealing technique advanced person can carry solid content up to the material below 35%; Continuous operation did not under normal circumstances have leakage in 8000 hours, was 3-5 times of traditional chemical pump sealing effect, and impeller design is an open architecture, so can not stop up because of the medium solid content is high, be the optimal sophisticated equipment that chemical industry is carried various materials.
