Abstract
The utility model relates to a CPN alkali pump. The CPN alkali pump comprises a pump body, pump vanes, a pump shaft, and so on, wherein a bearing box is arranged at the rear part of the CPN alkali pump; an adjusting bolt and a fastening bolt are arranged on the bearing box; a high temperature resistant bearing is embedded in the bearing box; and the high temperature resistant bearing is in interference fit with the pump shaft. The gap between an impeller and a pump cover can be adjusted effectively to make the pump generating negative pressure during operation, thereby effectively prolonging the service life of the mechanical sealing. The CPN alkali pump has the advantages of simple structure and convenient operation, and can greatly lower the cost of enterprises.
Description
Technical field: the utility model relates on the chemical industry pump commonly used, particularly relate to a kind of be used for carrying have the employed CPN alkali pump of certain corrosive liquid.
Background technique: at present, the CPN alkali pump that uses on the chemical industry all is to adopt double shrouded wheel, double shrouded wheel can not be carried the medium of impurity, result in blockage than being easier to, so the alkali pump of present industrial employing front opened impeller is more, but the backflow of front opened impeller is bigger, and its efficient is also lower, so power loss is bigger.This class is carried the pump of aggressive medium, owing to corroded, through use after a while, efficient can descend greatly, and often the accessory that need more renew if serious corrosion also needs to change again pump, causes very big loss to enterprise.So this pump adopts the back half-opened impeller, efficient is unaffected, and the gap between impeller and the pump cover is little, produces negative pressure during operation, effectively raises the working life of mechanical seal.
The purpose of this utility model just provides a kind of alkali pump that can adjust axial clearance mechanism, can reduce because of carrying the wearing and tearing of aggressive medium, to the influence of pump performance.
Summary of the invention: the purpose of this utility model is to realize like this, the CPN alkali pump is that the pump housing is arranged, the pump leaf, parts such as pump shaft are formed, it is characterized in that: the rear portion of described CPN alkali pump is provided with bearing housing, and have on bearing housing and adjust bolt and lock bolt, the inside of bearing housing is embedded with high temperature resistant bearing, and high temperature resistant bearing and pump shaft adopt interference fit.Pump adopts the back half-opened impeller, and efficient is unaffected, and the gap between impeller and the pump cover is little, produces negative pressure during operation, effectively raises the working life of mechanical seal.
Description of drawings: Fig. 1 is the structural representation of the utility model CPN alkali pump.
1, the pump housing 2, pump leaf 3, sealing cover 4, cooling liquid inlet 5, bearing 6, pump shaft 7 is adjusted bolt 8, bearing housing 9, lock bolt
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
In Fig. 1, pump leaf 2 adopts the back open architecture, can carry the medium of impurity, and pump shaft 6 runs up under the drive of motor, and power flows to pump leaf 2, reaches the purpose of fed sheet of a media.During concrete enforcement, the CPN alkali pump is through after a while running, because reason for corrosion, the spacing between pump leaf 2 and the sealing cover 3 strengthens, and the efficient of alkali pump constantly descends, and at this moment, can improve the power of alkali pump by adjusting axial clearance mechanism.Method is that lock bolt 9 is unclamped, adjusting the rotation of bolt 7 clockwise directions, adjust bolt 7 and prop up the pump housing 1, drive bearing housing 8 and move backward, because bearing housing 8 is embedded with high temperature resistant bearing, and high temperature resistant bearing and pump shaft 6 are interference fit, move backward thereby drive pump shaft 6, that is to say, by adjusting bolt 7, just pump leaf 2 can be moved backward, dwindle the distance between pump leaf 2 and the sealing cover 3, thereby reach the purpose that improves alkali pump power.By the cooling liquid inlet 4 that on bearing cap, is provided with, cooling liquid forcibly is transported in the bearing 5, can prevent effectively that bearing 5 is owing to wearing out that high temperature operation is brought, faults such as fatigue, the working life of improving alkali pump.
