introduction：(one)、Oil film bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Oil lubrication management： Data show that，The main cause of mechanical failure or early wear，More than half are related to lubrication technology management。Good lubrication management，Guard bearing、Abrasion or sintering of friction moving parts such as gears，Prevent and reduce wear and tear，antifriction

introduction： There are two significant advantages to making a pressure vessel spherical﹕ Under the same internal pressure﹐The stress on the shell of a spherical pressure vessel﹐Only half of the tangential stress on the shell of a cylindrical pressure vessel with the same diameter and wall thickness。therefore﹐Wall thickness of spherical pressure vessel﹐It can be thinned to half the wall thickness of the same diameter cylindrical pressure vessel﹔ At the same volume﹐The spherical pressure vessel has the smallest surface area。therefore﹐Under the same work pressure﹐The weight of the spherical pressure vessel is the lightest in the pressure vessel of the same volume。Spherical pressure vessels are commonly used as storage tanks﹐It is sometimes called a spherical pot。figure Outline of spherical pressure vessel

introduction：The holding pressure is set so that the resin does not produce reflux during cooling，And it can continue to replenish the insufficient space due to the cooling shrinkage of the resin，And get the best mold copy effect。 Keep the pressure set too high，Easy to cause rough edges、Excessive filling of the gate near the stress concentration and other undesirable phenomena，Keep the pressure setting too low，It is easy to cause too much contraction、Size instability and other phenomena。 Pressure maintenance must be accompanied by a pressure holding switch point and a pressure holding time setting to be effective。 Insufficient pressure retention can cause：1.hollow；2.bubble；3.The shrinkage rate increases；4.shaper
