Spring pump screw assembly matters needing attention 1, the assembly should be carefully cleaned screw parts, inspection, damaged parts should be replaced. 2, the drive shaft twenty thousand joints to the assembly, the seal should be checked for damage, the cavity filled with grease. 3, the correct installation of bearings so that the shaft rotation flexible, no jamming phenomenon. 4, shaft seal installation: packing culvert installation, should use the packing gland tight bolt position in the shell installation window, easy to adjust the bolt wrench. 5, the body pressed tight, tighten the nut should be uniform. 6, mechanical seal installation should be careful, friction deputy face should be clean and coated with grease. 7, when installing the stator, smear the rotor with a lubricant, the stator cavity surface, is conducive to the stator installation. 8, installation and assembly, the coupling installation deviation: △ γ ≤ 0.2mm, △ α ≤ 30. Chun Da screw pump disassembly steps 1, screw pump and motor from the emptying medium (to prevent the motor, toxic media wounding) 2, remove the screw pump body. 3, remove the screw pump stator, if necessary, according to the axis of the pump shaft for auxiliary. 4, remove the rotor and the middle shaft. 5, remove the drive shaft and shaft seal. 6, long-term without the screw pump, to make anti-rust treatment, the method is to use non-painted metal surface smear rust, including the shaft surface, packing housing cavity, and lubrication.
TOUGHENED GLASS
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury. Toughened glass is a kind of safety glass.
Toughened glass can be made on customer's request, clear toughened glass, ultra clear toughened glass, colored tinted toughened glass, printed toughened glass, back painted toughened glass, frosted toughened glass, toughened Laminated Glass, toughened Insulated Glass, toughened Vacuum Insulated Glass and so on.
Toughened glass can be used for furniture, buildings, doors, windows, walls, table tops, fence, partitions, railings, balcony, balustrade, shower room and so on.
