摘要:
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).

Fluid pumping system and method comprise a pumping chamber with inlet and outlet ports. The pumping chamber is in thermal communication with a thermal system for alternating the gas temperature inside the pumping chamber between heated and cooled states. A first valve controls a first fluid communication between the pumping chamber and the external environment, and a second valve controls a second fluid communication between the pumping chamber and the fluid container. The pumping chamber and the valves cooperate to generate a vacuum and a negative potential pressure of the gas inside the pumping chamber by the effect of the gas temperature alternation when the gas passes from a heated state to a cooled state and by controlling the first and second fluid communications. The generated vacuum and negative potential pressure inside the pumping chamber enable pumping of the fluid from the fluid container inside the pumping chamber.

An automatic draining system can include a driving mechanism, a first housing coupled to the driving mechanism, a vacuum pump and a bulkhead both coupled to the first housing, an inletting conduit and an outletting conduit both coupled to the bulkhead, a controlling device electrically coupled to the vacuum pump, a draining mechanism electrically coupled to the vacuum pump, and a first conduit and a second conduit both coupled to the first cylinder. The draining mechanism can include a first cylinder coupled to the bulkhead, a piston rod extending through the first cylinder; and a first piston assembly coupled to an end of the piston rod and received in the first cylinder. An end of the first conduit coupled to the first cylinder, the other end inserting into a pre-drained liquid. An end of the second conduit coupled to the first cylinder, the other end communicating with the outletting conduit.

The present invention relates to an apparatus (10) for vacuum processing articles (12). The apparatus comprises a processing region (14) in which articles can be vacuum processed at a processing pressure and a loading region (18) into which articles can be loaded into the apparatus at ambient pressure. A plurality of article carriers (20) are provided for carrying articles from the loading region to the processing region along an enclosed passage (24) so that articles can be vacuum processed. The carriers (20) comprise respective sealing means (26) for sealing against an inner surface of the passage when carrying articles along the passage. The sealing means (26) resist the flow of gas or vapour past the sealing means along the passage from the loading region to the processing region so that articles loaded at ambient pressure in the loading region and carried to the processing region can be vacuum processed at processing pressure.
摘要:
An agricultural sprayer includes a centrifugal pump used for transferring fluid from a nurse tank to fill the sprayer tank. It is sometimes required that the centrifugal pump be primed in order to perform the transfer of fluid and this priming is done by creating a vacuum in a priming line that is connected to a suction line extending between an inlet of the pump and to a discharge line of the nurse tank, with the vacuum being caused by routing a flow of compressed air through a venturi having its throat coupled to the priming line.
