Wear-resistant ceramic pipe to how to reduce the micro-motion wear measures? Wear-resistant ceramic pipe manufacturers for you in detail.
The physicochemical process under the condition of levy wear is very complex, and it is unrealistic to formulate a universal prevention method. Should be based on the specific friction vice involved in the wear mechanism and the influence of factors, to take appropriate measures. The protective measures that can be taken are described below.
(1) Optimize the structural design In order to minimize the occurrence of micromotion wear, consideration should be given to the structural design to reduce the relative motion and the composite effect of positive and tangential forces.
Under the premise of overall consideration of structural performance, economy, structural replacement, ease of installation, etc., the overall structure of wear-resistant ceramic pipe should be selected as far as possible in the design instead of bolting, flange connection, keying and so on.
Increasing the positive force in the contact area can increase the static friction, so that the amplitude of the micro-movement decreases, reducing the micro-movement wear of wear-resistant ceramic pipe. This can be achieved by increasing the compression force on the same contact surface, increasing the number of rivets or screws, or reducing the contact area under the same pressure and increasing the specific pressure between the contact surfaces. Increasing the tight-fitting surplus to 25~30um can effectively prevent the occurrence of micromotion wear.
In the micro-motion phenomenon is unavoidable, should minimize the contact area stress concentration.
In addition, the use of damping devices to reduce or eliminate vibration, improve lubricant delivery, reduce the geometric deviation of the surface, with a spherical surface instead of a cylindrical surface, completely exclude prismatic keys and half-moon keys, etc., are from the structure to prevent micromotion of wear and tear effective measures.
