Description

Technical Field

[0001] This utility model belongs to the technical field of hubs for servo level gauges, and specifically relates to a wound hub for servo level gauges. Background Technology

[0002] Servo level gauges are instruments used to measure and monitor liquid levels. They mainly consist of a servo system, a sensor, and a controller. By using the servo system, controller, and sensor, they monitor the liquid level and obtain real-time liquid data. They are widely used in the petrochemical, pharmaceutical, and food industries.

[0003] In servo level gauges, the control of the float's ascent and descent is achieved by a controller that drives a hub via sensors and a servo system. The float is connected to a steel wire, which is wound around the hub. The rotation of the hub winds and releases the steel wire, maintaining the float in equilibrium within the liquid. Existing hub technologies, such as... Figure 1 As shown, a spiral groove is provided around the hub to accommodate the steel wire. The spiral groove guides the winding and unwinding of the steel wire and enables precise winding and unwinding. The longer the steel wire wound on the hub, the larger the range of the servo level gauge. However, due to the spiral groove, the amount of steel wire wound is limited. When the required height of the servo level gauge is high, the length of the steel wire cannot meet the usage requirements, so improvement is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a winding hub for a servo level gauge. When the servo level gauge is installed at a high height, the wire is wound in multiple layers inside the wire storage groove, resulting in a longer winding length and a longer release length. This allows it to be used for servo level gauges installed at higher heights.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A wound hub for a servo level gauge, comprising

[0007] A hub body, wherein a retaining ring is fixedly installed on the right side of the hub body;

[0008] A partition ring is fixedly installed in the center of the circumference of the hub body. The partition ring is used to divide the hub body into a measuring part and a cable storage part. A spiral guide groove is provided around the measuring part. A spiral groove connected to the end of the spiral guide groove is obliquely provided around the partition ring.

[0009] As a preferred technical solution, the pitch of the spiral groove is greater than or equal to the pitch of the spiral guide groove.

[0010] As a preferred technical solution, the wheel hub body, the blocking ring, and the partition ring are integrally formed.

[0011] As a preferred technical solution, the wheel hub body is made of stainless steel.

[0012] The beneficial effects of this utility model are:

[0013] When in use, it is suitable for liquid level measurement needs at greater installation heights under the same geometric dimensions. During installation, the wire storage section has multiple layers of winding, while the spiral guide groove has a single layer of winding. When the servo liquid level gauge is installed at a high height, all the steel wire inside the wire storage section is released. The remaining steel wire smoothly transitions through the spiral groove on the baffle ring to the guide spiral groove of the measuring section. Then, the float can be lowered to the designated liquid level measurement area. The steel wire inside the spiral guide groove is wound and released to complete the accurate measurement. It has high measurement accuracy and strong applicability. Attached Figure Description

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 2-4 As shown, this utility model discloses a wound hub for a servo level gauge, comprising:

[0022] A wheel hub body 1, with a retaining ring 11 fixedly installed on the right side of the wheel hub body 1;

[0023] The partition ring 2 is fixedly installed in the center of the circumference of the hub body 1. The partition ring 2 is used to divide the hub body 1 into a measuring part 21 and a wire storage part 22. The measuring part 21 is provided with a spiral guide groove 23 around its circumference. The partition ring 2 is provided with a spiral groove 24 that is inclined around its circumference and connected to the end of the spiral guide groove 23.

[0024] When winding the wire, select a suitable length of steel wire according to the installation height. For example, when the installation height is 200 meters, prioritize winding a suitable length of steel wire into the spiral guide groove 23. The steel wire wound inside the spiral guide groove 23 is the measuring steel wire. The spiral guide groove 23 has a certain groove depth. After connecting the steel wire to the float, it can achieve precise release and winding of the steel wire. When winding, the steel wire will be guided and wound along the inner wall of the spiral guide groove 23 to avoid overlapping and messing up the winding wire. The steel wire wound inside the spiral guide groove 23 is a single layer winding. After the spiral guide groove 23 is fully wound with steel wire, pass one end of the steel wire through the spiral groove 24 and enter the wire storage part 22. Wrap the remaining steel wire around the wire storage part 22. After the first layer of steel wire is fully wound from left to right around the wire storage part 22, start winding the second layer of steel wire from right to left. Repeat this process to achieve multi-layer winding of the remaining steel wire until the steel wire is fully wound.

[0025] After the servo level gauge is installed, the control hub body 1 is rotated and released, and the float moves down until the steel wire wound around the wire storage section 22 is completely released. The float can then move down to the designated liquid level measurement area. For example, when the installation height is 200 meters, a larger range hub is needed to release a longer steel wire to meet the liquid level measurement requirements. Therefore, after the steel wire wound in the wire storage section 22 is released, the float can be placed directly in the designated liquid level measurement area. Through this principle, it can be applied to different range measurements at different installation heights. Under the same geometric dimensions, the applicable height is higher, and the practicality and applicability are improved. When measuring the liquid, the steel wire inside the spiral guide groove 23 is released and wound up through the hub body 1. The spiral guide groove 23 has a single layer of wound steel wire, and the liquid level measurement accuracy can reach ±1.0 mm, with a maximum liquid level measurement accuracy of ±0.4 mm, which is highly accurate.

[0026] The pitch of the spiral groove 24 is greater than or equal to the pitch of the spiral guide groove 23. The inclined spiral groove 24 facilitates the passage of steel wire for winding. The partition ring 2 has a certain thickness and high strength.

[0027] The wheel hub body 1, the blocking ring 11, and the partition ring 2 are all integrally formed; the whole is integrally formed, which has higher strength and is easier to install.

[0028] The hub body 1 is made of stainless steel; this material has excellent corrosion resistance and high strength, meeting the usage requirements of the servo level gauge in various harsh environments.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
