Abstract

The invention discloses an energy-saving hydraulic seal experiment table and a method thereof. The experiment table consists of an experimental cylinder, a driving loop of the experimental cylinder and a loading loop, and is characterized in that the experimental cylinder consists of a left cylinder cover, a left guide sleeve, a cylinder barrel, a piston, a piston rod, a right guide sleeve and a right cylinder cover; the driving loop of the experimental cylinder comprises a variable pump, a safety valve, a filter, a solenoid valve, etc; and the loading loop comprises a fixed displacement pump, an overflow valve, a filter, a solenoid valve, an accumulator and a stop valve. The experiment table can conduct experiments on various sealing rings of the piston and the piston rod, carry out online inspection of the sealing performance and the tribological properties of the sealing rings and the manufacturing quality of sealing elements, and perform experiments on a plurality of sealing elements to be detected simultaneously. The experiment table has the advantages of adjustable experiment speed and pressure, and excellent energy-saving effect.

Description

technical field [0001] The invention relates to a test bench for testing the comprehensive performance of hydraulic sealing components, in particular to an energy-saving hydraulic sealing test bench and a method thereof. Background technique [0002] Seals are important elements in hydraulic systems to prevent oil leakage, and their sealing performance and anti-wear performance will have an important impact on the reliability of the entire hydraulic system. At present, there is still a lack of effective technical means for the detection of newly developed sealing components. The commonly used method is: use a general friction and wear testing machine to conduct tribological tests on sealing materials, mainly to test their friction coefficient, wear resistance and other tribological properties. ; Since the friction conditions, mating materials, contact surface conditions, lubrication methods, etc. of this test are very different from the use of sealing elements in the actual ...

Problems solved by technology

At present, there is still a lack of effective technical means for the detection of newly developed sealing components. The commonly used method is: use a general friction and wear testing machine to conduct tribological tests on sealing materials, mainly to test their friction coefficient, wear resistance and other tribological properties. ; Since the friction conditions, mating materials, contact surface conditions, lubrication methods, etc. of this test are very different from the use of sealing elements in the actual hydraulic system, the results obtained by this test can only be used It provides a reference basis for understanding its tribological performance in the actual hydraulic system; and this kind of test cannot understand the anti-leakage performance of the sealing element in the actual hydraulic system, and cannot judge the processing and assembly quality of the sealing element; therefore, if the newly developed If the sealing element is applied in the actual hydraulic system only based on this test, it is likely to cause serious adverse effects on the machine equipment

Although people often directly assemble the sealing components on the tested hydraulic components (such as hydraulic cylinders), and carry out reliability life tests together with them; but the energy loss is high, and because the test device is not mainly for sealing components, the obtained Sealing element performance data is limited

In addition, some sealing element manufacturers even directly apply the newly produced seal products without any testing. On the one hand, this may affect the reliability level of mechanical equipment; Users of sealing elements provide reliable service life data
