Yuav ua li cas tiv thaiv stainless hlau fasteners los ntawm kev xauv
Fasteners kuj feem ntau hu ua cov qauv hauv kev ua lag luam, thiab yog cov ntsiab lus dav dav rau ib hom kev siv tshuab siv los txuas thiab txuas ob lossis ntau qhov chaw (lossis cov khoom siv) rau hauv tag nrho. Nws yog tus cwj pwm los ntawm ntau yam kev qhia tshwj xeeb, kev siv sib txawv, thiab qib siab ntawm kev tsim qauv, serialization thiab generalization. Fasteners yog cov khoom siv dav siv ntau tshaj plaws thiab yog qhov xav tau zoo.
cov kauj ruam/txoj kev
1. Correct product selection: Before use, confirm whether the mechanical properties of the product can meet the needs of use, such as the tensile strength of the screw and the guaranteed load of the nut. The length of the screw should be selected appropriately, and the 1-2 pitch of the nut will be exposed after tightening.
2. Before use, check whether the threads are rough and whether there are iron filings or dirt between the threads, which often lead to locking.
3. Lubricate the fasteners before use: It is recommended to use butter, molybdenum disulfide, mica, graphite or talc for lubrication. At present, wax dip treatment is generally used for lubrication and anti-locking.
4, pay attention to the use method:
a. The speed and force of the screwing-in should be appropriate, not too fast or too large. Use a torque wrench or socket wrench as much as possible, and avoid using an adjustable wrench or an electric wrench. Excessive speed will cause the temperature to rise rapidly and cause lock-up. Import pump valve
b. In the direction of force, the nut must be screwed in perpendicular to the axis of the screw.
5. The use of washers can effectively prevent the problem of over-tightening.
6. Kev xauv los yog qaug dab peg feem ntau tshwm sim ntawm cov khoom siv hlau stainless, aluminium alloy thiab titanium alloy cov ntaub ntawv. Cov hlau alloys lawv tus kheej muaj cov khoom tiv thaiv-corrosion. Thaum qhov chaw puas lawm, ib txheej oxide nyias yuav raug tsim rau ntawm cov hlau nto. tiv thaiv corrosion ntxiv. Thaum lub stainless hlau fastener yog xauv, lub siab thiab kub generated ntawm cov hniav yuav rhuav tshem cov oxide txheej, ua rau thaiv los yog shearing ntawm cov hlau threads, thiab ces sticking. Thaum qhov tshwm sim no tshwm sim, cov hlau tsis muaj steel fasteners yuav raug kaw tag nrho thiab tsis tuaj yeem muab tshem tawm lossis txuas ntxiv xauv. Feem ntau qhov kev thaiv no _txiav_adhesion_locking tshwm sim hauv ob peb feeb xwb, yog li kev nkag siab zoo ntawm kev siv hom fasteners no tuaj yeem tiv thaiv qhov tshwm sim no.
