Abstract
An apparatus and a method are shown for removing or moving a viscous fluid such as grease from a first unit such as a bearing e.g. a ball bearing to a second unit via a hose or pipe. According to the method, the apparatus is shown pumping a viscous fluid from an outlet (11) of a first unit (1) to an inlet (10) of a second unit (2) through a hose or pipe (7), a vacuum pump (3) is connected to the hose or pipe (7) and the viscous fluid is moved through the hose or pipe (7) by suction; wherein the hose or pipe (7) comprises an inlet (8) for gas such as air, and the flow of gas through the inlet (8) is controlled by a valve (9).
Claims8
An apparatus for pumping a viscous fluid from an outlet (11) of a first unit (1) to an inlet (10) of a second unit (2) through a hose or pipe (7), a vacuum pump (3) is connected to the hose or pipe (7) and the viscous fluid is moved through the hose or pipe (7) by suction;
- wherein the hose or pipe (7) comprises an inlet (8) for gas such as air, and the flow of gas through the inlet (8) is controlled by a valve (9), wherein the first unit (1) is a bearing such as a ball bearing.
A method for pumping a viscous fluid from a first unit to a second unit through a hose or pipe, wherein the viscous fluid is provided at an outlet of the first unit and the second unit is subjected to a constant vacuum, consequently the viscous fluid is pulled or moved into the hose or pipe,
- wherein a flow of gas is allowed into the hose or pipe between the outlet of the first unit and the inlet of the second unit, wherein the vacuum pump provides a pressure p2 in the second unit of a vacuum of 1000 to 1 mbar/760 to 0.75 Torr.
