Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to an online monitoring box low-flow oil detection flow meter. Background Art

[0002] When the online oil monitoring box is used in different detection environments, it will encounter different position detection pressures and flow rates. For example, in large shield machinery, cement plants, hydroelectric power plants, thermal power plants, etc., the pipeline pressure and flow of the hydraulic system are generally relatively large, and their pressures and flows are different. At this time, after the online oil monitoring box device is installed, various pressures and flow rates will appear. Because the flow rate during the monitoring box detection will have a significant impact on the detection, it is necessary to set a range for the monitoring box flow (30-60ml / s) to ensure the stability of the oil detection after the monitoring box is installed in the oil pipeline and to ensure the accuracy of the oil detection. The online monitoring box requires a smaller flow rate to detect oil. Most of the existing flow meters on the market detect water or other solutions. When detecting large flow rates, the volume is relatively large and takes up a lot of space, which is inconvenient to use.

[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an online monitoring box low-flow oil detection flowmeter, which is convenient for monitoring low-flow oil and convenient for application.

[0005] The technical solution of the present utility model is as follows: Provide an online monitoring box low-flow oil detection flowmeter, comprising: an oil chamber seat, a middle cover plate connected to the oil chamber seat, an upper cover plate connected to the middle cover plate, a sensor, a rotor assembly, a main board, an oil inlet interface, and an oil outlet interface; the oil chamber seat and the middle cover plate form an oil chamber, and the middle cover plate and the upper cover plate form an electrical chamber; the oil inlet interface and the oil outlet interface are both connected to the oil chamber; the sensor and the rotor assembly are installed in the oil chamber, and the sensor faces the rotor assembly; the main board is arranged in the electrical chamber, and the main board is electrically connected to the sensor. The rotor assembly comprises: a pin shaft installed on the oil chamber seat and / or the middle cover plate, a rotor sleeved on the pin shaft, and the sensor faces the rotor. Preferably, the oil chamber seat, the middle cover plate, and the upper cover plate are flat.

[0006] Oil enters the oil inlet, impacting the rotor assembly and driving the rotor assembly to rotate. The sensor senses the rotor's rotational speed, which the mainboard then converts into oil flow. In this solution, the oil chamber is formed using an oil chamber seat and a middle cover, while the electrical chamber is formed using a middle cover and an upper cover. This significantly reduces the product's size, facilitating its use in online oil monitoring boxes. Furthermore, the flat design of the oil chamber seat, middle cover, and upper cover allows for a flatter structure, further reducing the product's size and fully meeting the requirements for online oil monitoring boxes.

[0007] Furthermore, the low-flow oil detection flowmeter of the online monitoring box further includes: an aviation plug installed on the middle cover plate or the upper cover plate, and the aviation plug is electrically connected to the main board.

[0008] Furthermore, the two rotor assemblies are arranged in two groups, with the oil inlet facing between the two rotors. With two rotor assemblies, each sensor can detect the rotational speed of one rotor, convert it into flow rate, and then average it, resulting in more accurate monitored data. The two rotors are symmetrically positioned about the extended line of the oil inlet, minimizing errors caused by positional differences.

[0009] By adopting the above scheme, the utility model provides a low-flow oil detection flowmeter for an online monitoring box. In this scheme, an oil chamber seat and a middle cover plate are used to form an oil chamber, and a middle cover plate and an upper cover plate are used to form an electrical chamber, which can fully reduce the size of the product and facilitate its application in an online oil monitoring box. Moreover, the oil chamber seat, the middle cover plate and the upper cover plate are designed to be flat, which can make the structure of the product flat, further reducing the size of the product, thereby fully meeting the application requirements in an online oil monitoring box.
