Abstract
The utility model belongs to oil level indicating devices used for preventing an oil film in a bearing pedestal for a dynamic-hydrostatic oil film bearing from being leaked, and particularly relates to an oil level indicator. A main body of the oil level indicator is a cylindrical shell, wherein a ventilation cover is installed in an upper opening of the cylindrical shell through screw threads, an air release valve is installed on the ventilation cover, the lower part of the wall of the shell is provided with an oil inlet pipe, the bottom surface of the shell is provided with an oil outlet pipe an upper opening of which is an oblique opening, the oil outlet pipe with the oblique opening is caused to extend into the shell, and the wall of the shell is provided with an observation window provided with a transparent partition plate. The oil level indicator not only can avoid the higher liquid level of the oil film bearing of a motor as well as the lubricating oil leakage caused by level fluctuation generated due to negative pressure, eliminate accident potential of motor insulation, which is generated due to lubricating oil leakage, prolong the service life of the motor, but also has stronger operation visibility during application, thus being convenient for operation control and daily maintenance work.
Description
Technical field
The utility model belongs to equipment and adopts moving-static pressure filmatic bearing, prevents the oil level indicating device that the oil film in the bearing seat leaks, particularly a kind of oil level indicator.
Background technology
The main motor of steel plant's flat cold-rolled sheet milling train has adopted moving-static pressure filmatic bearing, in actual the use, because the factors such as liquid fluctuating that liquid level is higher and negative pressure causes in the bearing seat, oil film oil in the bearing seat leaks along the labyrinth seal groove of axle head, the oil product of revealing sticks between the stator and rotor of motor under the circulation wind action of air channel, causes the accelerated deterioration of electrical machine insulation easily.
Summary of the invention
The purpose of this utility model is to provide a kind of oil level indicator, can prevent that not only the lubricating oil that dynamo oil film bearing liquid level liquid fluctuating higher and that negative pressure causes causes from leaking, eliminate because the accident potential that oil leakage produces electrical machine insulation, prolong the serviceable life of motor, and operation has stronger visuality in using, and is convenient to operation control and daily servicing.
The purpose of this utility model is achieved in that a kind of oil level indicator, the body of oil level indicator is a drum shape housing, mouth is installed with ventilating cover by screw thread thereon, vent valve is installed on ventilating cover, bottom on housing wall is being provided with oil inlet pipe, the flowline of tilt port that is suitable for reading is being set on the bottom surface of housing, and the tilt port flowline stretches in the housing, and the inspection window with transparent baffle is being set on housing wall.
The utility model mainly is made up of oil level indicator body, transparent observing window, ventilating cover and vent valve.The indicator inner chamber is provided with the inclined mouth type liquid back pipe, the height of angle liquid back pipe is a little less than the labyrinth seal under the axle head in the installation process, avoid the leakage of the higher generation of actual liquid level of bearing seat, the actual liquid level that forms in bearing seat can be checked by transparent watch window, for preventing that negative pressure has been installed vent valve open in usual to the influence of liquid level in the cavity above ventilating cover.In actual use, because the oil leakage problem that liquid level liquid fluctuating higher and that negative pressure causes causes has obtained solution preferably.
The utility model has prevented that not only the lubricating oil that dynamo oil film bearing liquid level liquid fluctuating higher and that negative pressure causes causes from leaking, eliminated because the accident potential that oil leakage produces motor, prolonged the serviceable life of motor, and operation has stronger visuality in using, and is convenient to operation control and daily servicing.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing, and accompanying drawing is a sectional structure synoptic diagram of the present utility model.
Embodiment
A kind of oil level indicator, as shown in drawings, the body 1 of oil level indicator is a drum shape housing, mouth is installed with ventilating cover 2 by screw thread thereon, vent valve 3 is installed on ventilating cover 2, and the bottom on housing wall is being provided with oil inlet pipe 6, and the flowline 5 of tilt port that is suitable for reading is being set on the bottom surface of housing, tilt port flowline 5 stretches in the housing, and the inspection window 4 with transparent baffle is being set on housing wall.The central horizontal line of tilt port flowline 5 tilt ports is lower than the labyrinth seal groove bottom under the motor shaft end.
Claims (2)
