Double-acting variable technology of liquid-gas equipment

Abstract

The invention relates to a double-acting variable technology of liquid-gas equipment, mainly aims to overcome the serious defect that a traditional single-acting variable technology must depend on eccentricity or inclination with large radial destructive force to realize variable, breaks through the usual viewpoint that variable cannot be realized through double action, and adopts a double-acting concentric deformation rail to realize non-radial force variable. Therefore, the defect of radial force of eccentric or inclined variables is overcome, and the important breakthrough of no radial force and no axial force variable is achieved. In the fields of hydraulic pressure, pneumatic pressure, refrigeration, chemical engineering and the like, after the non-radial force variable of fluid equipment needing to be adapted to complex working conditions is realized by utilizing the technology, the machine performance can be greatly improved, the energy can be obviously saved, and the working efficiency can be greatly improved. And the service life of the machine can be obviously prolonged, and the maintenance cost is greatly reduced.

1. Technical field [0001] The invention provides an effective cracking method and innovative technology for the real situation that the vital variable technology is seriously restricted by the radial destructive force in the field of fluid machinery such as hydraulics and pneumatics; Significantly lower costs at higher performance and create technical conditions for improved product competitiveness. 2. Background technology [0002] Hydraulic, pneumatic, refrigeration, chemical and other industries need to use pumps or motors, and many fields of use with changing environments also require variable pumps and variable motors to better adapt to changing working conditions. However, the current variable pump and variable motor must rely on eccentricity or inclination to achieve variable, and the amount of variable is proportional to the amount of eccentricity or inclination; and eccentricity and inclination are both out of balance, as long as there is pressure, it will produce r...

AI Technical Summary

Problems solved by technology

However, the current variable variable pumps and variable variable motors must rely on eccentricity or inclination to achieve variable variables, and the amount of variable is proportional to the amount of eccentricity or inclination; and eccentricity and inclination are both unbalanced states. As long as there is pressure, radial displacement will occur. The greater the variable, the greater the radial force, which will not only seriously affect the dynamic seal, but also aggravate the wear of the moving parts, especially the service life of the bearing will be greatly shortened due to excessive radial load

Although this disadvantage is not significant in low-pressure applications, it is very fatal in high-pressure hydraulic fields
