Precautions for the Operation of Electro-Hydraulic Servo Universal Testing Machine

Microcomputer-controlled electro-hydraulic servo universal testing machine collector hydraulic servo automatic control , Automatic measurement , Data acquisition, screen display and test result processing are integrated. With the host machine under the oil cylinder as a platform, it is equipped with imported oil pumps, electro-hydraulic servo valves and PC servo controllers to realize multi-channel control and complete the automatic test process. Control , automatic measurement and other functions have the characteristics of good professionalism, high reliability and easy upgrade, and can be continuously enriched and improved with the development of testing machine measurement and control technology and changes in testing standards.

Precautions for the Operation of Electro-Hydraulic Servo Universal Testing Machine : YN6Textile Testing Instruments, Testing Equipment Manufacturer

1.Perform the corresponding test with a suitable jig , Otherwise not only the test will not be very successful, but also the jig will be damaged: The electro-hydraulic servo universal testing machine is usually only equipped with a jig for standard samples.If You want to make non-standard samples, such as stranded steel, lapped steel, etc., must be equipped with proper fixtures, there are also some ultra-hard materials, such as spring steel, etc., need to use special material clips, otherwise the fixture will be damaged;
2 .Cleaning and cleaning: During the test, it is inevitable that some dust will be generated, such as the surface of some parts, but even worse when this dust enters the hydraulicsystem enters, there will be very serious consequences, such as blocking the valve bore and scratching the surface of the piston, so cleaning after each use is very important, and the testing machine must be kept clean;
3. Electro-hydraulic servo universal testing machine hydraulic oil: must regularly check the fluid level of the oil tank and add oil in time, generally the oil should be changed every 2000-4000 hours of operation, but the most important thing is that the oil temperature should not exceed 70℃ and the cooling system must be switched on when the oil temperature exceeds 60°C;
4. Electro-hydraulic servo universal testing machine filter: Filters without a clogging indicator are usually replaced every 6 months. In the case of filters with a clogging indicator, these must be constantly monitored and replaced immediately if the indicator alarms;
5 Accumulator: Some electro-hydraulic servo univesrsal testing machines are equipped with accumulators, and the accumulator must ensure the pressure is in the normal operating state, if it is found that the pressure is insufficient, it must be refilled immediately; only for energy storage6. Periodic inspection of components: All pressure control valves, flow control valves, pump controllers and signaling devices such as pressure relays, limit switches and thermal relays must be inspected regularly Cold copper pipe is broken or leaking;
8. apply lubricating oil regularly to avoid dry friction;
9. The fasteners should be locked regularly: the vibration after the specimen breaks often causes some fasteners to loosen, and regular inspections need to be carried out in order to large losses due to loose attachmentto avoid elements. 10. Other controls: Be vigilant and pay close attention to details to spot signs of accidents early and avoid major accidents. This applies in particular to the initial commissioning of the electro-hydraulic servo universal testing machine equipment. Always be on the lookout for external leaks, contamination, damaged components, and unusual noises from pumps, couplings, etc. YN6Textile Testing Instruments, Testing Equipment Manufacturer
