Embodiment Construction

[0018] Such as figure 1 As shown, the present invention provides a tilting pad bearing that can monitor the residual axial force of the pump on-line, including the tilting pad bearing, and the tilting pad bearing includes six arc-shaped pads. The tilting pad bearing is provided with a test element and a display instrument electrically connected to the test element. A hole is opened on the back of the tilt pad bearing, and the test element is placed in the hole. The test element includes a measuring Pressure components and temperature measuring components.

[0019] Specifically, the load cells are the top load cell 3 placed on the back of the top arc-shaped tile 1 and the bottom load cell 4 placed on the back of the bottom arc-shaped tile 2 . And the two load measuring elements are symmetrical to the center of the tilting pad bearing. Correspondingly, there are two temperature-measuring elements, which are placed on the back of the arc-shaped tile adjacent to the load-measuri...

Abstract

The invention discloses a tilting pad bearing capable of monitoring residual pump axial force on line. The tilting pad bearing comprises a tilting pad bearing, wherein the tilting pad bearing is provided with a testing element, and a display instrument electrically connected with the testing element; a hole is formed in the back surface of the tilting pad bearing; the testing element is positioned in the hole; and the testing element comprises a pressure measuring element and a temperature measuring element. The bearing and a method can be used for instantly measuring and monitoring a numerical value of residual pump axial force on line under various scene working conditions.

Description

technical field [0001] The invention relates to a tilting pad bearing for testing the residual axial force of a pump, and is especially suitable for the tilting pad bearing which can monitor the axial force on-line. Background technique [0002] Tilting pad bearings are composed of 3-5 or more arc-shaped pads. When each pad is working, it can automatically swing with the change of the load of the rotor, forming multiple oil pockets around the journal. Tilting pads not only have a large load-bearing capacity, low power consumption, but also can withstand radial loads in all directions. Pumps using tilting pad bearings have a certain residual axial force when they stop running. In order to better monitor the axial force, direct or indirect detection methods are generally used. [0003] Direct measurement is by pasting the pressure (pull) strain gauge on the tilting pad bearing block, the electrical signal received by the pressure (pull) strain gauge is continuously transform...
