Problems solved by technology
[0004] The invention provides a reversing device for a lubricating oil flow tester and a lubricating oil flow tester to solve the problems caused by gaps between the annular interfaces in the traditional pneumatic commutator during the introduction and diversion of lubricating oil. The phenomenon of lubricating oil splashing makes it easy for the lubricating oil to splash and drip onto the measuring device, and even leak from various sealing parts

The present invention discloses a commutation device for a slide oil flow tester and the slide oil flow tester. The commutation device comprises an upper support plate fixedly connected into a tester working chamber and a lower support plate which is fixedly connected to the upper support plate through a support rod. The upper support plate is equipped with a rotation shaft which is arranged along the plate surface vertical direction of the support plates and extends between the upper support plate and the lower support plate and a driving mechanism. A part of the rotation shaft between the upper support plate and the lower support plate is sleeved by an oil disk component which is rotated along the rotation shaft to carry out slide oil division and prevent the outward splashing of the slide oil. Multiple plate through joints are uniformly and circumferentially distributed on the upper support plate along rotation shaft. The oil disk component is provided with multiple oil guidance sleeves. The lower support plate is provided with measuring cups for directly taking slide oil from the oil guidance sleeves. The plate through joints, the oil guidance sleeves, and the measuring cups are in one to one correspondence. The oil disk component is connected to an oil return pipe which is arranged on the lower support plat and is used for guiding the shunt slide oil back to an oil tank. The commutation device is applicable to an environment with a large temperature change.
Description
technical field [0001] The invention relates to the field of lubricating oil flow test equipment for a turboshaft engine, in particular to a reversing device for a lubricating oil flow tester. In addition, the present invention also relates to a lubricating oil flow tester comprising the above-mentioned reversing device for the lubricating oil flow tester. Background technique [0002] The turboshaft engine lubricating oil flow tester includes an electromagnetic reversing valve, a cylinder and a reversing device. The design temperature range of the test medium is between 30°C and 100°C. Thermal expansion and contraction may occur during different temperature processes. Repeated temperature changes will affect the sealing of various parts of the commutator. [0003] In the process of lubricating oil introduction and diversion in traditional pneumatic commutators, lubricating oil splashes due to gaps between the annular interfaces, which makes it easy for the lubricating oil ...
