What is the degree of wear of the jaw crusher, eccentric shaft and bearing bush of the jaw crusher? What are the quality requirements?

If the shaft wears little, just to repair its geometry, it can be turned on the lathe to bring the journal to the correct geometry and then reduce the bearing inner diameter accordingly. However, after several such treatments, if the journal size is reduced by 5% compared to the original, no turning is allowed, and the new shaft should be replaced.

Jaw crusher is working under the impact load, Pap alloy lining, duration of work on the bush around for about two years, the deadline, you will need to re-cast.

If the eccentric shaft and the bearing bush, the mandrel and the bearing bush are worn, and the top clearance is greater than 1.5 times of the original assembly clearance, it needs to be adjusted or replaced; if the oil groove wears 1.5 mm, the oil groove should be re-opened and adjusted. The gap between the upper cover of the connecting rod head and the eccentric shaft, when worn to more than 1.5 times the assembly clearance, also needs to be adjusted or replaced with a new one.

When the Babbitt alloy on the bearing shell has a deep peeling or a large abrasion, it should be recast. For the quality of the bearing bush, the following requirements are required: the surface of the babbitt alloy should be uniform, dull, silvery white; the surface layer of the babbitt should not have ash, cracks, blisters, shrinkage holes, etc.

Round Open Water Cooling Tower

The whole structure is solid and light;the body and water pond is manufactured with reinforced glass fibre (FRP glass fiber reinforced plastics),never being corrosive. The surface finish is added with ultraviolet inhibitor,which can resist sunshine attack and damage.

All steel and iron material is processed through galvanizing by dipping,Ocorrosion resisting and durable.

Special designed axial-flow type air blower applies belt reduction gear,reducing low noise and sufficient wind; tailor-made water-drop noise
reduction carpet to eliminate water sound.

Apply special design PVC water block curtain (water-stop) to prevents plashing) remarkably; pressure drop loss is slight and splashing loss i under 0.001%.

Special designed water sprinkler with big bore diameter,which won' t cause blocking but the sprinkling effect is very good. It is installed in the tower,so it won' t bee polluted by outside dust and foreign matters.

Apply cellular vacuum molding heat dissipation material, stagger arrangement surface has grooves and the heat exchange effect is especially good.


Water pond applies slant design, easy to wash, containing less water; the operating weight is lower, but the water tank is very big, so it won't absorb air.

The cooling tower support is light and solid, convenient to assembly no matter there is suspension iron rack or not.
