Description

Technical Field

[0001] The utility model relates to the technical field of liquid level detection, in particular to an anti-wave device for an oil level gauge. Background Art

[0002] The oil level gauge is a device that measures the oil level in the bearing oil tank of the unit. For example, the FINE brand oil level gauge used by our company is Figure 1 As shown in the figure, the oil level gauge is divided into two parts, separated by the mounting plate. The lower part is immersed in the oil. To provide access to the measuring area, a float is installed. The float floats on the surface of the liquid and is connected to a magnetic ball via a connecting rod. The magnetic ball's range of motion is within the upper part of the oil level gauge. The upper part of the oil level gauge is marked with graduations, and each graduation corresponds to a magnetic flap. When the magnetic ball reaches a certain graduation, the corresponding magnetic flap flips under the influence of the magnetic ball.

[0003] An air guide hole 1 is located at the top and bottom of the probe's measuring section. These holes are designed to utilize the principle of communicating vessels, ensuring that as the external liquid level fluctuates, the internal level also fluctuates until the internal and external levels are aligned. Therefore, when the liquid level fluctuates, a certain amount of oil and air will flow into or out of the oil level gauge through these holes. If this flow is particularly rapid, the oil level gauge reading will fluctuate dramatically. The speed of this flow, in other words, represents the instantaneous flow rate. According to the equation flow rate Q = SV (where the cross-sectional area S is proportional to the hole diameter, and the instantaneous flow velocity V during fluctuations is assumed to be constant), a larger hole diameter results in a greater instantaneous flow rate and, consequently, a greater instantaneous change in the oil level reading. When the unit is operating, the large shaft in the bearing oil sump rotates, stirring the oil, causing fluctuations in the oil level gauge reading and potentially triggering false alarms. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an oil level gauge anti-wave device, so that the alarm of the oil level gauge caused by liquid level fluctuation will no longer occur.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an oil level gauge wave-proof device, including a sleeve arranged on the oil level gauge probe measuring part, the sleeve is tightly arranged on the outside of the probe measuring part, and an air guide groove corresponding to the upper air guide hole is provided on the sleeve.

[0006] Preferably, the sleeve is provided with a plurality of air guide grooves corresponding to the upper air guide holes, and the opening sizes of the plurality of air guide grooves are different.

[0007] Preferably, the upper end of the sleeve is provided with a flange for fixedly connecting to the oil level gauge mounting plate.

[0008] The utility model provides an oil level gauge anti-wave device. This device does not pose a safety risk to personnel or equipment during installation. After installation, the fluctuation of the oil level gauge during operation of the unit is significantly alleviated, and no false alarm caused by fluctuation has occurred during operation so far. This prevents false alarms of the oil level gauge caused by oil level fluctuations during operation of the unit, reduces the workload of operation monitoring personnel, and is conducive to the safe operation of the unit.

[0015] like Figure 3-4 As shown, an oil level gauge wave-proof device includes a sleeve 2 mounted on the oil level gauge's probe measuring part. The sleeve 2 is tightly mounted on the outside of the probe measuring part, and an air guide groove 3 corresponding to the upper air guide hole 1 is provided on the sleeve 2.

[0016] Preferably, the sleeve 2 is provided with a plurality of air guide grooves 3 corresponding to the upper air guide holes 1, and the opening sizes of the plurality of air guide grooves 3 are different. A plurality of air guide grooves 3 of different sizes are provided, and the air guide groove 3 of the required size can be selected according to actual conditions to be aligned with the air guide holes 1 for installation.

[0017] Preferably, the upper end of the sleeve 2 is provided with a flange 4 for fixedly connecting to the oil level gauge mounting plate. The flange 4 is provided to facilitate the connection of the device with the original equipment.

[0018] When using, Figure 5 As shown, the air guide groove 3 blocks the original air guide hole 1, making the opening of the communicating vessel smaller and reducing oil level fluctuations. The sleeve 2 blocks the lower air guide hole 1 and opens a small groove at the upper air guide hole 1, making the upper air guide hole smaller and reducing liquid level fluctuations caused by excessive instantaneous flow.
