Daim teb Railway

The railway is one of the most important inventions and means of transportation of mankind. For centuries, mankind has continued to innovate its technology, and the technology of railways and locomotives has not yet reached its peak.

Today, railways around the world have more transport responsibilities than ever before, and the demands placed on locomotive manufacturers and their suppliers are constantly changing. Shorter product cycles and technological innovation, the use of newer, more advanced, lighter, more energy-saving and environmentally friendly materials, and even the ever-changing division of labor require continuous innovation and adaptation.

Hlau Xov Ntxig, self-tapping thread insert and key locking insert are widely used in railways and locomotives as new and innovative fastening technologies. High-speed railways tau tsim tshwj xeeb hauv peb lub teb chaws, thiab high-ceev EMUs yog ua hauj lwm nyob rau hauv coob ntawm tag nrho cov loj railway kab thoob plaws lub teb chaws thiab xa mus rau ntau lub teb chaws. Aluminium alloy tau dhau los ua cov khoom tseem ceeb ntawm cov tsheb thauj khoom vim nws lub teeb yuag thiab zoo sealing zog. Txawm li cas los, qhov muag ntawm cov ntaub ntawv aluminium alloy ua rau tsis muaj zog shear tsis kam nyob rau hauv threaded sib txuas. Kev ua haujlwm ncaj qha ntawm cov xov ntawm cov khoom siv hauv paus tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm kev tsheb ciav hlau sib dhos thiab kev ua haujlwm. Aluminium alloys yuav tsum tau siv cov xov sheaths los xyuas kom meej qhov ruaj khov thiab kev ntseeg siab ntawm kev sib txuas.

Nyob rau hauv ntau yam ntawm domestic EMUs, threaded sheaths yog siv nyob rau hauv ntau yam threaded kev twb kev txuas lug xws li tsheb interiors, sab nrauv suspensions, and under-car hoisting. The main types include wire thread inserts, Yus tus kheej tis xov ntxig, and key locking thread inserts. The CRH1 EMU has a stainless steel body and does not require the use of threaded sheaths; the CRH2 EMU mainly uses steel wire threaded inserts; the CRH3 EMU mainly uses self-tapping threaded inserts, and is also used in some large-diameter pipe connections. Wire thread inserts are used in parts; key locking thread inserts are used in CRH5 EMUs.
