What are the mechanisms of the action of the eye plate and the cutting ring of the concrete pump?
The working principle of the utility model is that the rubber spring is pressed under the action of the pretightening force of the expansion nut, and the cutting ring is tightly jointed with the glasses plate. The cutting ring and the glasses plate belong to a relative motion coupling component, and after the abrasion is generated, the rubber spring can compensate the abrasion amount of the eyeglass plate and the cutting ring by the elasticity of itself, and eliminate the abrasion clearance. When the wear cutting ring reaches a certain degree, the rubber spring compression amount is zero, no pressing force on the cutting ring, screw expansion nut, S tube welding body back tension and compression recovery of rubber spring, then the glasses plate and rubber spring compression, clearance compensation. This method ensures the sealing performance of the glasses plate and the cutting ring well.
Cost reduction function: because of the function of the glasses plate and the cutting ring, they replace the wear between the feed port and the material cylinder, and protect the service life of the two.
The S tube valve is composed of an eyeglass plate, a cutting ring, a rubber spring, a special-shaped nut, a transition sleeve, a sealing member, a size bearing and a S pipe welding body.The glasses plate and the cutting ring mainly play the following roles:The sealing function: they mainly work with spring and rubber, through the pressure self balancing and rubber spring automatic gap compensation, the floating cutting ring has self sealing effect, thereby increasing the conveying pressure s tube valve.
