Summary of the invention
The purpose of this utility model is: a kind of Pendular ring type chlorine gas pump is provided, increases air displacement, make a pump can satisfy the demand of 50,000 tons of/year caustic soda amounts, increase work efficiency, increase the rigidity and the sealing of pump simultaneously, increase the service life.
Technical solution of the present utility model is: this chlorine gas pump comprises the pump housing, impeller, pump shaft and front and rear covers, set up the inlet and outlet mouth on the two ends of the pump housing separately, impeller is installed in the pump housing by front and rear covers through pump shaft, front and rear covers is installed on the pump shaft by the front and back bearings support, connect the front and back bearings gland on the front and back bearings support, front and rear covers connects the pump housing, establishing air inlet on the front and rear covers distributes window and exhaust to distribute window, blade is connected on the impeller blowout patche and constitutes impeller, is positioned at axially to establish one group of air inlet/outlet on the both sides of impeller end face.
In the Pendular ring type chlorine gas pump of the present utility model, the pump housing is installed on the pump platform by the dual-gripper support.
In the Pendular ring type chlorine gas pump of the present utility model, establish the cooling chamber on the front and rear covers.
In the Pendular ring type chlorine gas pump of the present utility model, establish mechanical seal on the front and rear covers.
During work, gas enters pump chamber from the suction port of the pump housing one end, air inlet/outlet by the impeller end face distributes window from the air inlet that both direction flows to front and rear covers, impeller rotates to when air inlet/outlet and communicates the exhaust of front and rear covers when distributing window, gas distributes window by the air inlet/outlet of impeller end face from the exhaust that both direction flows to front and rear covers, is discharged by the relief opening of the pump housing the other end then.
The utlity model has following advantage: 1. be positioned on the both sides of impeller end face and axially establish air inlet/outlet, gas divides to flowing, and prolongs leaf longevity; 2. the dual-gripper support has increased the rigidity of pump, has reduced the vibration of pump, and running has steadily prolonged working life; 3. double mechanical seal, the maintenance operation is briefly convenient; 4. former conjuncted big tegillum is that front and back are covered greatly, has removed the taper tegillum of distributor effect, and impeller no longer needs to grind with the conical surface of tegillum and cooperates, and reduces cost on the one hand, reduces the leakage approach on the other hand; 5. can reduce impeller diameter increasing impeller length by former relatively chlorine gas pump, satisfy the demand of producing 50000 tons of caustic soda amounts per year, improve working efficiency.
