More Information
Summary:A negative pressure control device of vortex compressor comprises a negative pressure cavity formed on the side of the upper frame holding the fluid on the discharge side of the vortex compressor and the lubricating oil from the lubricating oil storage tank, a by-pass pipeline connecting the negative pressure cavity with the suction side of the vortex compressor and a negative pressure control part opening and closing selectively the by-pass pipeline. The invention can reduce pressure difference between inner part and outer part of the small negative cavity to prevent the lubricating oil overleaking from the negative cavity.
