Passed through between the pump housing and pump cover and by axle, described impeller all has blade construction, the described lateral lobe of impeller two for the left and right sides
Piece is distributed for staggered, and maximal clearance is 9mm between the blade of the every side of described blade, between the blade of the every side of described blade
Minimum clearance is 2mm, and the blade of described impeller is the structure pointed to clockwise, and further, double suction sealing ring is located at pump cover
Lower inside and be connected with pump cover, further, 5mm gap, further, key are left between double suction sealing ring and impeller
It is connected positioned at the centre position of axle and with axle, further, axle sleeve is located at the outer surface of axle and is connected with axle, further, axle
There is machine envelope between the pump housing, further, between axle and pump cover there is machine envelope.
Set in the utility model, above the pump housing and an axle is placed in the middle of pump cover, the pump housing and pump cover, one section of connection electricity of axle
Two bearing bodies, two axle sleeves and an impeller are set on machine, axle.Main shaft is fixed on the pump housing by bearings at both ends body and realizes fortune
Turn, so that the operating of impeller, produces kinetic energy, realize the conveying to medium.The impeller for the structure that is in staggered distribution using blade,
It is difficult to result in blockage, realizes the uniform effect of the reliable and stable starching of starching pump.
Beneficial aspects：The utility model is for general pulp pump, optimization design and life-cycle by energy-conservation
Cost Theory is designed, and carries out transformation and optimization to blade wheel structure, both sides impeller is changed to be in staggered distribution, and improves the equal of paper pulp conveying
Evenness, performance is greatly improved.And axle sleeve is provided with outside axle, the service life of axle is improved, by bearing body come fixing axle, makes
Axle is more stablized at work, improves operating efficiency.
