ZMM type low frequency heavy load reciprocating friction and wear tester
Brief introduction：The tester is independently developed by Heng Xu test machine and has a re
The tester is independently developed by Heng Xu test machine and has a reciprocating function of low frequency heavy load and large stroke friction and wear test machine. The machine is mainly used on double or single side heavy load reciprocating test, and can realize reciprocating test on end face. It is of practical significance for some heavy wear resistant materials or structures, such as supporting wear plate and side bearing wear. Friction coefficient test of plate, core plate wear plate and so on. The main engine adopts the high strength base and adopts the constant distance reciprocating motion to realize vibration friction. In order to strengthen the vibration of the base under the action of alternating friction force, it is preloaded with no gap guide guide, and the loading unit also adopts self fixed core loading; the machine is attached to the friction performance testing of the elastic side bearing of the standard TB/T 3269-2011 railway freight car.
The general technical parameters are as follows:
Serial number | entry name | Technical indicators |
1 | Tighten force | |
1.1 | Maximum two-way tightening force | 30KN |
1.2 | Loading precision | ±1％ |
1.3 | Loading mode | Automatic loading |
2 | friction coefficient | |
2.1 | Measurement method | Real time acquisition |
2.2 | measurement accuracy | ±2% |
2.3 | Parking protection | Overload automatic parking protection |
3 | Heat dissipation system of sample | |
3.1 | Operation mode | Start the cooling cycle above 25 degrees C |
3.2 | Temperature control precision | ±5℃ |
4 | Vibration frequency | Stepless adjustable |
5 | amplitude | ±15mm |
6 | Host power | about 5kW |
The test machine adopts advanced servo motor technology, elevator technology and modular design. The structure is novel and the specimen is clamped conveniently. Through the multi-function data acquisition unit, the sampled tension / pressure sensor and temperature sensor signal are input to the computer for real-time analysis and processing. It has automatic display and print measurement in the middle, the automatic and the printing. The result and other functions provide convenient, reliable and advanced modern testing means for the manufacturing units and installation units of the side bearing wear plate and the disc wear plate. At the same time, it is also a recommended product for the study of low frequency heavy load reciprocating end friction and wear tester.
Heng Xu test machine is committed to the development and production of a new type of high end friction and wear testing machine. It is directed by "innovation and focus", and aims to "provide high quality and sophisticated testing equipment for the society" as its purpose, and continuously improves product technology. At present, some of the friction and wear testing machines have obtained advanced techniques and related patents. Sharing results, products priced reasonably, cost-effective, and willing to work together with people with lofty ideals to revitalize China, win-win cooperation!
