Abstract
The utility model relates to an alkali pump commonly used in the industry, which is composed of a pump body, a pump shaft, pump leaves, etc. An axial clearance adjusting mechanism is arranged to adjust the distances between the pump leaves and a sealing cover, so that the defects that because corrosive media are conveyed, the clearance increases, the power lowers, etc. are eliminated, and the service life of the alkali pump is extended.
Description
The utility model relates to industrial alkali pump commonly used.
At present, the alkali pump of industrial use 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 using after a while, efficient can descend greatly, the frequent accessory that need more renew, if seriously corroded, also need to change again pump, cause very big loss to enterprise.
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.
The purpose of this utility model is to realize like this, alkali pump is that the pump housing is arranged, parts such as pump leaf, pump shaft are formed, it is characterized in that: the rear portion of described alkali pump is provided with pump cover, and on pump cover, have and adjust bolt and lock bolt, the inside of pump cover is embedded with high temperature resistant bearing, and the bearing of anti-the high humidity adopts interference fit with pump shaft.Also be provided with sealing cover between described pump leaf and bearing, sealing cover is fixed by bolts on the bearing cap, and has the cooling liquid inlet on bearing cap, and cooling liquid can be carried out forced cooling to bearing by inlet.
Fig. 1 is the structural representation of the utility model alkali pump.
1, the pump housing 2, pump leaf 3, sealing cover 4, cooling liquid inlet 5, bearing 6, pump shaft 7, adjustment bolt 8, pump cover 9, lock bolt
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.Through running after a while, because reason for corrosion, the spacing between pump leaf 2 and the sealing cover 3 strengthens, and the power 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, and adjusting the rotation of bolt 7 clockwise directions, adjusts bolt 7 and props up the pump housing 1, driving pump cover 8 moves backward, because pump cover 8 is embedded with high temperature resistant bearing, and high temperature resistant bearing is interference fit with pump shaft 6, thereby drive pump shaft 6 moves backward.That is to say,, 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 adjusting bolt 7.By the cooling liquid inlet 4 that on bearing cap, is provided with, cooling liquid forcibly is transported in the bearing 5, can prevent the faults such as aging, fatigue that bearing 5 brings owing to high temperature operation effectively, the working life of improving alkali pump.
Claims (2)
1, alkali pump is to have the pump housing (1), pump leaf (2), pump shaft parts such as (6) to form, and it is characterized in that: the rear portion of described alkali pump is provided with pump cover (8), and has adjustment bolt (7) and lock bolt (9) on pump cover (8).
2, alkali pump according to claim 1 is characterized in that: also be provided with sealing cover (3) between described pump leaf (2) and the bearing (5), sealing cover (3) is fixed on bearing (5) and covers, and has cooling liquid inlet (4) on bearing cap.
