Description

Technical Field

[0001] The invention relates to a hydraulic training device, which is mainly used for performing functional tests on various hydraulic components and can conveniently form a distributed luminous electro-hydraulic control system. Background Art

[0002] There are currently two solutions for hydraulic training equipment in the prior art: one is to use traditional hydraulic oil as the experimental medium, supply oil to the training equipment through a hydraulic oil pump, and perform related actions through hydraulic components for demonstration, and the hydraulic components used also rely on hydraulic oil to work. For example, Chinese patent CN201420509848.2 discloses a flexible hydraulic system training platform, in which the transmission medium used in the training platform is traditional hydraulic oil. In this technical solution, the system is connected through a hose quick-plug connector, so when plugging and unplugging the connector, a certain degree of oil leakage will occur; at the same time, when the component fails or the component seal ages, accidental oil leakage will also occur. This leads to a harsh environment in the experimental site, inconvenient operation, and difficult cleaning and maintenance, which reduces the enthusiasm and initiative of students in practical learning. In addition, the flammability of the oil will bring safety hazards, and the discharge and improper treatment of waste oil will pollute the environment; as well as the waste of hydraulic oil and the increase in the cost of purchasing hydraulic oil. The other is to use water as the experimental medium. For example, CN201911319607.5 discloses a multifunctional environmentally friendly water hydraulic teaching experimental table. Although it solves the two major shortcomings of hydraulic oil, flammability and pollution, this solution has great limitations due to the rustiness and freezing of water. Since water is easy to rust, more expensive materials need to be used to prevent rust, thereby increasing costs; at the same time, because water is easy to freeze at low temperatures, it is easy to freeze the components, making the maintenance of the equipment more cumbersome.
