RH quantitative volumetric lathe pressurized thin oil fitting grease distributor central lubrication system

●The RH3 type checking volumetric distributor is suitable for volumetric lubrication system. When the system is pressurised, oil is stored, and when the system is depressurised, oil is injected. The product can deliver lubricant to each lubrication point according to the specified oil injection volume specification and quantitatively.

●This kind of detected volumetric distributor has four forms: two oil outlets, three oil outlets, four oil outlets and five oil outlets. The product is widely used in printing, plastics, packaging, machine tools and other machinery and equipment lubrication system.

Working Principle

●1st>>The oil which sent by the lubrication pump is injected by the main pipe A

●2nd >>umbrella-shaped two-way valve B is pushed upward and through the passage C flows into the piston chamber F.

●3rd>>Under the action of the pressure oil, the metering piston moves downward and the spring G is compressed and accumulated, and the oil is stored and start metering.

●4th>>When the oil pressure in the main pipe A is released(pressure released),the umbrella valve B moves downward due to the pressure, and spit the exit E,so that the metering oil in the piston enters the oil pipe H through the discharge port E, and the oil is delivered to the lubrication station.

●5th>>the signal pin protrudes when metered,and retracted when supply oil to the lubricator station
