Failure Analysis of Fracture of Outlet Valve Washer

A R175A diesel engine in the spring before the overhaul of the maintenance of cylinder liner replacement, piston, piston rings, valves and races, connecting rod, the supply of three precision couplings, there are still difficult to start the fault, and barely started after the operation Strenuous, no significant increase in engine speed when fueling the door. The inspection found insufficient pump oil pressure, decomposition pump, found that the valve gasket was significantly scratched, and there is a fracture. Turned out to replace the original valve when the hand with a screwdriver pry out the valve gasket accidentally broken, so that the fuel pump high, low oil collusion, resulting in the failure. Replacement of a new oil valve gasket troubleshooting. As the oil valve gasket installed pressure, reduced diameter, tight hoop in the valve seat, pry easily damaged, therefore, the replacement of the oil valve valve should be replaced at the same time the gaskets.

Die Cutting Machine

Die cutting machine is also known as a beer machine and CNC punching machine, it is mainly used for the corresponding non-metallic materials, sticker, EVA, double-sided adhesive, electronics, mobile phones, pads and other die-cut (full cut or kiss cut), the indentation and bronzing job fit, automatic waste discharge, die-cutting machines use blades, metal molds, steel wire (or steel plates carved into the template) to apply some pressure by stamping version, printed materials or cardboard rolled and cut into a certain shape. Cutting machines are very important equipment in the post press packaging molding process.

Die-cutting Machine Working Principle
Working principle of die cutting machine is to use the steel knife, metal molds, steel wire (or steel plate engraving templates), the pressure applied by embossing version, make the printed materials or cardboard rolled and cut into a certain shape. If the pressure of the entire printed materials cut into a single graphics products, this is called die-cutting; if use the two templates of upper and lower by the mold to heat up to a certain temperature, to leave the bending groove marks is called indentation on the surface of the printed products stamping having a three-dimensional effect of the pattern, or font called bronzing; if use a substrate to multiplex on another substrate, this is called bonded; excluded from inter authentic outside the remaining portion of said above collectively referred to as die-cutting technology for waste; the working principle of the automatic die cutting machine is the feeding machine feeder parts sent the paper to the front and the regulatory and side provisions bit, and then the tooth row send the paper to the die secondary positioning for cutting, after die-cutting and then again from teeth row to the platoon served stripping agencies, after stripping and then enter the delivery section, thus completing a die-cutting job.
