Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pump station technology, and specifically relates to a pressure monitoring device for a hydraulic pump station. Background Technology

[0002] As the power source of a hydraulic system, the hydraulic pump station plays a crucial role in providing stable and reliable hydraulic power to various actuators. In industrial production, the pressure stability of the hydraulic system directly affects the safety and efficiency of equipment operation. Abnormal pressure fluctuations or exceeding limits can not only lead to decreased equipment performance and reduced production efficiency, but also potentially cause safety accidents, resulting in personal injury and property damage. Therefore, real-time and accurate monitoring of the hydraulic pump station pressure is of paramount importance. Hydraulic pump station pressure monitoring devices have emerged to address this need. They collect real-time pressure data from the hydraulic pump station by installing pressure sensors and other monitoring elements, and transmit this data to a monitoring system.

[0003] When installing pressure monitoring devices, technicians typically wrap sealing tape around the threaded connecting pipe at the bottom of the device as a primary means of ensuring a tight seal. However, this traditional sealing method is often ineffective in practical applications and struggles to cope with complex and changing industrial environments. On one hand, the sealing tape may lose its sealing function due to aging, wear, or improper installation; on the other hand, relying solely on tape sealing is too simplistic and lacks a multi-layered protective mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a pressure monitoring device for a hydraulic pump station to solve the problem of insufficient sealing in existing pressure monitoring devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure monitoring device for a hydraulic pump station, comprising a gauge body; a threaded connecting pipe connected to the bottom end of the gauge body; and a sealing assembly further provided on the threaded connecting pipe, the sealing assembly comprising: an adjusting member sleeved on the threaded connecting pipe; the top of the adjusting member being threadedly connected to the threaded connecting pipe; and a sealing member installed at the bottom end of the adjusting member, the sealing member not being threadedly connected to the threaded connecting pipe. During the installation of the pressure monitoring device, the threaded connecting pipe is screwed into the threaded sleeve on the hydraulic pump station. During the screwing process, the threaded sleeve on the hydraulic pump station will squeeze the sealing member, and under the limitation of the adjusting member, will push the sealing member in the opposite direction, thereby achieving a sealing effect. Combined with the sealing tape originally wrapped on the threaded connecting pipe, a double seal is achieved.

[0006] Preferably, the adjusting component includes an adjusting nut screwed onto the threaded connecting pipe and a spring fixed to the bottom end of the adjusting nut. The spring is connected to the sealing component. The position of the spring can be adjusted by adjusting the adjusting nut. During the later upward movement of the sealing component, the spring is squeezed, and the spring's rebound pushes the sealing component in the opposite direction toward the end of the threaded sleeve on the hydraulic pump station. The rebound force generated by the spring at different positions is also different.

[0007] Preferably, the sealing element includes a washer fitted onto the threaded connecting pipe, the washer being fixed to the bottom end of the spring to receive the spring's subsequent rebound force, and a rubber ring being bonded to the bottom end face of the washer, the rubber ring abutting against the threaded sleeve on the hydraulic pump station to achieve a seal.

[0008] Preferably, the bottom end face of the rubber ring is also provided with a groove. The groove is annular and can be easily inserted into the top position of the threaded sleeve of the hydraulic pump station to achieve a seal.

[0009] Preferably, the front surface of the watch body is provided with a protective glass, which is not shown in the figure, and a cleaning component is provided on the protective glass.

[0010] Preferably, the cleaning assembly includes a collar and a scraper fixed to the outside of the collar. The scraper is in contact with the protective glass on the front surface of the watch body. By rotating the collar, the scraper rotates around the center of the protective glass, thereby achieving rapid cleaning of impurities on the protective glass.

[0011] Preferably, a screw hole is provided at the center of the protective glass on the front surface of the watch body, and a limiting nut is screwed into the screw hole. The limiting nut passes through the collar, thereby installing the collar and ensuring that the scraper rotates around the center of the protective glass.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a sealing component is added. During the installation of the pressure monitoring device, the sealing component can automatically achieve a tight fit with the top of the connection area of ​​the hydraulic pump station, simplifying the installation process. At the same time, the sealing effect it creates complements the existing conventional sealing methods, forming a double sealing structure. This double sealing design effectively solves the problem of insufficient sealing in the existing structure, improves the sealing reliability at the connection between the pressure monitoring device and the hydraulic pump station, and ensures the stability of equipment operation.
