slurry pump sleeve worn to what extent should be replaced?

    Role is to protect the shaft sleeve, the filler into friction with the shaft and sleeve friction filler. So bushings are vulnerable parts of a centrifugal pump. Bushings wear to what extent should replace it? This problem is a lot of use of units is often overlooked, the following Shijiazhuang Pump Works to provide you with the most simple test method:

   Friction and stuffing the outer sleeve between the filler makes several different shades of ring wear marks appear on the outer sleeve. These will affect the wear scar axial seal tightness, resulting in lower pressure centrifugal pump outlet during operation.
    Wear sleeve available micrometer or vernier caliper to measure the diameter size, the measured dimensions compared with the standard OD checks. Generally, the depth of the circumferential outer annular sleeve of the wear scar may not exceed 0.5mm.
For serious wear Heavenly recommendations should be replaced slurry pump pump bushings to ensure axial seal tightness.
