The operation method and daily maintenance of the bellows ring stiffness testing machine

Bellows ring stiffness testing machine is widely used in the measurement of the ring stiffness of thermoplastic pipes and glass fiber reinforced plastic pipes with circular cross-sections. It meets the requirements of pe double-arm corrugated pipes, winding pipes and various pipe standards, and can complete the pipe ring stiffness , Ring flexibility, flatness, weld tension and other tests. Let's give you a detailed introduction to the operation method and daily maintenance of the bellows ring stiffness testing machine. 1. The operating method of the bellows ring stiffness testing machine 1. The user is used to do simple tensile tests, compression tests, etc. when purchasing. You only need to bring conventional accessories. For what kind of tension, bending, peeling, etc. Tear and other accessories that are not needed at all, so users must not think that the more they buy, the better, after all, extra money will be charged for those that exceed the conventional configuration. 2. Due to the characteristics of the pipe material, the corrugated pipe ring stiffness testing machine sometimes needs to reach 3 meters in the test space, but often some users choose the 3 meter model when the test space is about 2 meters, which also causes Part of the waste, and the longer the length of sheet metal, screw, etc., the higher the price. 3. The models of this equipment can be roughly divided into digital display type and microcomputer control type. No matter which type of the two equipment, they fully meet the mechanical standards of pipe inspection, but some of the functions and the way of displaying data are different, like For most small and medium-sized enterprises, when the data and functional requirements of the test are not too many and the digital display can meet the situation, there is no need to spend more money to buy a computer-controlled one. 2. Routine maintenance of the bellows ring stiffness testing machine 1. Before the test, the system must be warmed up for more than 20 minutes, so that the temperature drift is small. 2. The buffer oil should be kept clean, and the oil level should be replaced immediately when the height of the oil level is less than two-thirds of the cylinder depth. 3. Before starting the bellows ring stiffness tester, check whether the frictional active part should be filled with lubricating oil. 4. Before holding the test piece, the brake handle must be jammed, and release after adding the test piece. 5. Lubrication is not allowed for the main bearing of the dynamometer. The surface of the friction wheel in the gearbox shall not be refueled or splashed with oil stains. The friction surface shall be clean and the inclined block on the swing arm shall not be violently impacted. 6. After the test of the bellows ring stiffness testing machine is completed, cut off the power supply, and then clean the surface of the testing machine to protect it in time. 7. The tensile machine is maintained twice a month on average. The operator of the instrument should carefully read and understand the maintenance of the instrument, and maintain the instrument so that the instrument is always clean and tidy, and the parts and accessories are complete and safe to ensure the normal operation of the instrument. The above is the relevant introduction of the operation method and daily maintenance of the bellows ring stiffness testing machine, I hope it can bring you help.
