introduction：1.Increase the seal pressure，Adjust the pressure spring Fuller pump in use，The tongue valve needs to be switched on and off continuously。When the tongue valve is open，That is, when the material is arranged，There is bound to be part of the conveying material of the low-pressure compressed air into the discharge chamber。Because the spiral of the cylinder part is longer，Greater resistance，So this part of the compressed air is not easy to channeling to the hopper。The only way out is through the discharge end 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，To reduce

introduction：intro：This paper introduces several simple methods to identify the advantages and disadvantages of optical cable keyword：Optical cable one、rind：Indoor optical cables generally use polyvinyl or flame retardant polyvinyl，Smooth appearance、light，pliable，Easy peel。Poor quality fiber optic cable skin finish is very poor，Easy and tight sleeve、Aramid adhesion。 Outdoor opticalPEThe sheath shall be of high quality black polyethylene，After forming the cable, the outer skin is smooth、light、Uniform thickness、Free of bubbles。Poor quality fiber optic cables are generally produced from recycled materials，The fiber optic cable has a rough skin，Because there are many impurities in the raw material，A closer look reveals that there are many tiny pits in the fiber optic cable，shop

introduction：Stainless steel wire drawing generally has several effects:Straight silk、Snow striation、Nylon pattern。 A straight line is an uninterrupted line from top to bottom，Generally, the fixed drawing machine parts can be moved before and after。 Snow pattern is the most popular one now，Its made up of a little bit of spec points，The effect can be achieved with worm sandpaper。 Nylon lines are made up of lines of varying lengths，Because the nylon wheel is soft, it can be worn on uneven parts，Reach nylon。 Stainless steel wire drawing is very particular about procedures and processes，Generally cooperate with the wire drawing machine to repair and restore the position of the product scratch and weld，Finally achieve the overall drawing artistic effect。 Cylinder surface one
