Inclined shaft type hydraulic transformer and voltage transformation method

Abstract

The invention relates to an oblique axle type hydraulic transformer. A hydraulic transformer reconstructed according to the prior oblique axle type hydraulic pump / motor is different to realize continuous voltage transformation of between 0 and 120 degrees under the condition of unchanging a structure of a shell. A transition plate is arranged between a rear cover and the shell; the rear end of a rotating rod is connected with an actuating mechanism or an angle is adjusted manually so as to achieve the aim of changing pressure. The invention puts forward a concept of using the transformation ratio of the hydraulic transformer by stages so as to fully utilize the function of voltage transformation which can be realized by the prior hydraulic transformer and utilize parts of mature elements of the hydraulic pump / motor.

Description

technical field [0001] The invention relates to a new type of hydraulic component, in particular to an inclined-axis hydraulic transformer capable of step-by-step voltage transformation. Background technique [0002] At present, the invention patents and utility model patents on hydraulic transformers are basically about how to overcome the defects of throttling during the voltage transformation process of hydraulic transformers, including the invention patents and utility model patents proposed by domestic and foreign universities such as Achten University and Zhejiang University in China. The new patent enables the hydraulic transformer to fully realize its variable voltage range from zero to positive infinity. [0003] The inventions of Achten University and Zhejiang University are mainly to change the distribution plate and the back cover of the hydraulic transformer. They have one thing in common, that is, the high pressure port is led to the center through the distribu...

Problems solved by technology

However, this change will also introduce another problem, that is, with the increase of the rotation angle of the valve plate, the matching angle of the notch between the rear end surface of the valve plate and the rear cover will continue to increase, so that the thrust on the rear end surface of the valve plate will continue to increase. increase, and then the supporting force continues to decrease, which eventually leads to an increase in internal leakage of the transformer, a decrease in transformation efficiency, and even loss of transformation capability

Therefore, this kind of hydraulic transformer has limited voltage transformation capability, which limits the application range of hydraulic transformers.
