The direct relationship between the inter stage liner, spacing liner, and waiting part liner, as well as the contact point and contact angle with the pump shaft neck globe valve: According to standard regulations, the contact area between the bearing back and the bearing seat should be within 60%

Above, the contact point density on the sliding contact surface at the journal is maintained at 2-4 points per square centimeter, and the contact angle is kept between 60 "and 90". Bracket and base plate. Timely detect the fatigue situation of vibrating support components to prevent a decrease in natural frequency due to a decrease in strength and stiffness.

Gap and vulnerable parts. Inter level bushings, spacing bushings, and precision machined bushings from Dalian Lianghui Machinery ensure appropriate clearance between motor bearings; Adjust the gap between the impeller and the volute appropriately with a pressure reducing valve; Regularly inspect and replace wear-resistant parts such as impeller mouth rings, pump body mouth rings, inter stage bushings, and baffle bushings.
