How To Deal With The Repair Of The Bearing Chamber Of The Dispersive Kneader

2022-01-03

In industrial production, the wear and tear of equipment is very common. For example, a kneader is a kind of high-viscosity and ultra-high-viscosity elastoplasticity produced by a pair of cooperating and rotating blades (usually Z-shaped) to produce semi-dry state or rubber-like viscous plastic materials. Equipment for uniform mixing, mixing, kneading, crushing, dispersing, and regrouping into various chemical products.

The kneader is an ideal equipment for kneading, mixing, vulcanizing and polymerizing high-viscosity, elastoplastic materials. The kneader is a special mixing and stirring equipment. The most commonly used one is to use two Z paddles with a side-by-side tangent differential arrangement, that is, one stirring paddle is fast and the other is slow to facilitate shearing. The cutting force and different paddle speeds enable the mixed materials to be quickly sheared, so that the materials can be mixed evenly.

The wear of the bearing position and the bearing chamber of the kneader is generally caused by the dimensional tolerance of the components, the assembly process and the wear problem under the heavy-duty operation environment. Once the wear occurs, it will inevitably cause the kneader blades to run unsteadily and cause vibration or unexpected shutdown.

According to the condition that the kneader shaft has been disassembled and checked off-line, the measures of Cable Lei "Machining Technology" are used to control the concentricity during repair, and at the same time avoid the common problems of thermal stress, deformation, and fracture in repair welding.

The steps for on-site restoration of Sole Carbon Nano polymer materials are as follows:

① Correct the coaxiality of the lathe;

② Degrease the worn parts of the bearing position;

③ Carry out pre-turning and rough treatment on the worn parts of the bearing position;

④Machining and processing the shaft repair surface to make it conform to "Solei Machining Technology";

⑤ Reconcile and apply the carbon nano-polymer SD7101 material, and apply it several times to avoid pores until it is slightly higher than the original size;

⑥The material is cured, heated and cured for 2 hours, and then machined and turned to the original shaft size;

⑦Add 0.03-0.05mm on the basis of the journal size tolerance.

The above is about how to deal with the repair of the bearing room of the kneader. If you want to know more about our company`s dynamics or products, you can consult us.
