Matters related to hydraulic system pipe of rubber tensile testing machine

The hydraulic system isTension testerAn important component, Jinan Hengsi Shengda Instrument Co., Ltd. has detailed description of the precautions for the hydraulic system pipe of the rubber tensile tester:

Screw rubber into the joint bodyTension testerBefore the hydraulic system oil circuit board or valve body, clean the threads of the joint body, apply sealant or wrap it with polytetrafluoroethylene plastic tape along the thread to improve sealing and prevent leakage from outside the joint. However, it should be noted that the wrapping direction of the sealing belt must be rotated along the thread direction, generally 1 to 2 turns. There are many layers of wrapping, and the joints are prone to loosening during work, which will cause oil leakage.

If a fluid sealant is used as the filler between the threaded buckle and the buckle, the temperature must not exceed 60 degrees Celsius, otherwise it will melt and cause liquid to overflow from the buckle. When tightening, the force should not be too large, especially the joint body of the conical pipe thread. Excessive tightening force will cause cracks and lead to leakage. Also note that rubberTension testerThe joints should be cleaned with kerosene and blown with air.
