Abstract:
A lubricant pump (14) and a method thereof are disclosed. The lubricant pump (14) includes a pump base (32) and a reservoir housing (30). The pump base (32) and the reservoir housing (30) define a lubricant reservoir for storing lubricant. One or more pump elements (34) extend at least partially into the lubricant reservoir. Heaters (36) are disposed on the pump base (32) proximate the pump elements (34). The heaters (36) are configured to heat the local area surrounding the pump elements (34), to thereby reduce the viscosity of the lubricant at the pump elements (34). The heaters (36) are electrically connected to a thermal switch (38) to control activation and deactivation of the heaters (36). With the lubricant pump (14) and the method thereof, the thermal switch (38) can control the heater (36) based on air temperature rather than the temperature of the lubricant, so the viscosity of lubricant is well controlled.
Abstract:
A desk accessory includes a first panel (12) comprising a back end (12a), a front end (12b), stay means (34) on the front end, and a support (14) that tilts the first panel to a gently inclined position. The support comprises a back portion behind the first panel for supporting desired items, and for providing needed weight to stabilize the first panel in a position conveniently extended over the edge of a desktop. The support also comprises a front portion that supportively engages the underside of the first panel to stabilize it in the substantially extended position. With elbows supported on armrests of a chair, the first panel can be used in a comfortable, laidback sitting posture for reading and writing, for using a laptop computer, or for using a computer keyboard with a wrist rest. A computer keyboard or the laptop computer can also be used comfortably on the back portion of the support while the first panel is being used for reading and writing.
Abstract:
A tank for transporting, storing, and dispensing viscous materials is disclosed having a cylindrical body, and spherical ends. The tank further comprises an ellipsoidal follower device used to force the viscous material through the tank, the follower device having an upper half, and lower half, and a centerline. A plurality of stabilizing fins are rigidly connected to the ellipsoidal follower device at the centerline and extending axially along the tank's inner wall, the stabilizing fins disposed between a periphery of the ellipsoidal follower device and an inner wall of the cylindrical body. The fins serve as an anti-tipping device to maintain the follower in the proper orientation even upon rested in a horizontal position.
Abstract:
An oil pump is provided. The oil pump comprises a shell, a rotor mounting part (11) disposed at an end of the shell, and a rotor mechanism (2) disposed on the rotor mounting part (11). The shell has an inlet (161) and an outlet (162) and defines a low-pressure oil chamber (12) and a high-pressure oil chamber (13) therein. The high-pressure oil chamber (13) and the low-pressure oil chamber (12) are located at the same side of a periphery of the rotor mounting part (11) side by side. An engine cover comprising the oil pump and an engine comprising the engine cover are also provided.
Abstract:
Die Erfindung betrifft eine Förderpumpe für die Zufuhr von Schmierstoff an wenigstens eine Schmierstelle, mit wenigstens einem Antriebsmodul (1 , 6, 6', 18a, 18b) und wenigstens einem Pumpenmodul (3), wobei jedes Antriebsmodul (1 , 6, 6", 18a, 18b) und jedes Pumpenmodul (3) aus einem modularen System gewählt ist, das mehrere Antriebsmodule und/oder mehrere Pumpenmodule umfasst, die jeweils wenigstens einen Anschlussbereich (A) aufweisen. Dabei sind die Anschlussbereiche (A) derart aneinander angepasst, dass das wenigstens eine Antriebsmodul (1 , 6, 61, 18a, 18b) gegen wenigstens ein weiteres Antriebsmodul und/oder das wenigstens eine Pumpenmodul (3) gegen wenigstens ein weiteres Pumpenmodul austauschbar ist.
Abstract:
Die Erfindung betrifft eine Dosierpumpe (1), insbesondere für Schmierstoffe, sowie ein Verfahren zum Langzeitschmieren einer Schmierstelle (16) vorzugsweise über mehrere Jahre. Die Dosierpumpe (1) ist mit wenigstens einem durch eine Betätigungseinrichtung (5) antreibbaren Dosierkolben versehen. Um eine möglichst kompakte Bauweise zu erzielen, weist die Betätigungseinrichtung (5) wenigstens ein Heizelement (8) und ein durch das Heizelement (8) aufheizbares Dehnstoffelement (6, 7) auf. Durch Energiezufuhr an das Heizelement erwärmt sich das Dehnstoffelement und der Dehnstoff dehnt sich aus. Dadurch wird der Dosierkolben (4) bewegt. Die Erfindung betrifft schließlich auch einen Schmierstoffbehälter (18), der an der Dosierpumpe luftdicht befestigbar ist. Durch luftdichte Befestigung wird eine Alterung des Schmierstoffes in der Dosierpumpe vermieden und eine fortlaufende Versorgung der Schmierstellen (16) mit Schmierstoff über die eigentliche Haltbarkeit des Schmierstoffes hinaus ermöglicht.
Abstract:
The invention regards a mobile lubrication pump, comprising: - a motor for driving the pump for producing a pump pressure, - a pressure monitor for measuring the pump pressure, - a motor controller for regulating the operation of the motor, - a data processing unit (DPU) for communicating with the motor controller, and for receiving: 1) input from the pressure monitor, and 2) user input related to: pump capacity and/or lubrication target, and wherein the data processing unit is configured to determine and communicate a motor speed and/or motor torque to the motor controller based on the received input 1) and 2).
