Description

Technical Field

[0001] The utility model relates to a vibration monitoring device for a process motor in an oil and gas module, and particularly to a running vibration monitoring system for a process motor in an oil and gas module. Background Art

[0002] As a key power device in offshore engineering equipment, the running stability and reliability of the process motor in the oil and gas module are crucial to the performance of the overall equipment. In the offshore engineering environment, the marine environment is complex and changeable, and various natural forces such as waves and tides, as well as internal factors such as rotor imbalance and system resonance, will cause the vibration of the motor. The anti-vibration support, as an important support structure, can reduce the impact of external vibration on the motor and ensure the normal operation of the motor.

[0003] At present, most process motors have a large structure and generate large vibrations during operation. The existing supports only play a supporting role and have a single function; resonance occurs between the support and the motor, shortening the service life and affecting the running accuracy of the motor, forming a vicious cycle. The current anti-vibration design of the support mainly uses the installation of damping springs, and the anti-vibration effect is limited; if the elastic coefficient of the spring is too small, the supporting force applied under load will be insufficient, and if the elastic coefficient is too large, it will not be able to play the role of shock absorption and filtering of ground undulations, making the selection difficult. At the same time, the existing shock absorption structure cannot monitor the vibration situation of the motor in real time. Summary of the Invention

[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a running vibration monitoring system for a process motor in an oil and gas module that improves the shock absorption ability and can monitor the running vibration situation of the process motor in the oil and gas module in real time.

[0005] A running vibration monitoring system for a process motor in an oil and gas module of the utility model includes an anti-vibration support for supporting the process motor. The anti-vibration support includes a bottom plate, and the bottoms of four spiral springs arranged vertically are respectively fixed at the four corners of the bottom plate. The tops of the spiral springs are fixed on a top plate; a pressure sensor is placed in the middle of the top wall of the top plate; a circular magnetic sheet is pasted in the middle of the bottom surface of the top plate; a disc spring is fixed in the middle of the bottom plate, and the top of the disc spring is fixed on the bottom surface of the top plate. An electromagnetic coil is arranged inside the disc spring. The height of the electromagnetic coil is lower than the height of the disc spring, and the central axis of the electromagnetic coil coincides with the central axis of the magnetic sheet; the pressure sensor is connected to the signal input end of a computer through a data line, and the signal output end of the computer is connected to the control module of the electromagnetic coil.

[0006] Advantages of the present utility model: The combination of the helical spring and the disc spring improves the shock absorption ability, expands the available elastic coefficient range of the spring, and reduces the difficulty of type selection; the electromagnetic damping generates a reaction force to offset the vibration force, achieving active control of shock absorption; the disc spring is detachable, adapting to different usage requirements, with a wider application range, and being convenient for replacement and maintenance, and the device can monitor the vibration condition of the process motor during operation in real time.

[0010] The present utility model will be described in detail below with reference to the drawings and specific examples.

[0011] As shown in the drawings, a vibration monitoring system for the operation of a process motor of an oil and gas module according to the present utility model includes a shock isolation support for supporting the process motor 8. The shock isolation support includes a bottom plate 4, and the bottoms of four helical springs 3 arranged vertically are respectively fixed at the four corners of the bottom plate. The tops of the helical springs 3 are fixed on the top plate 2; a pressure sensor 1 is placed in the middle of the top wall of the top plate 2; a circular magnetic sheet 5 is pasted in the middle of the bottom surface of the top plate 2; a disc spring 7 is fixed in the middle of the bottom plate 4, the top of the disc spring 7 is fixed on the bottom surface of the top plate 2, and an electromagnetic coil 6 is arranged inside the disc spring 7. The height of the electromagnetic coil 6 is lower than the height of the disc spring 7, and the central axis of the electromagnetic coil 6 coincides with the central axis of the magnetic sheet 5.

[0012] The pressure sensor 1 is connected to the signal input end of the computer 9 through a data line, and the signal output end of the computer 9 is connected to the control module of the electromagnetic coil 6.

[0013] The working principle is as follows:

[0014] When this device is in use, place the four supports on the four corners of the oil and gas module process motor 8 respectively. When the oil and gas module process motor 8 operates, vibrations are generated. The pressure sensor 1 detects the vibrations of the shock-absorbing supports, converts the detected vibration conditions into the force on the shock-absorbing supports, and transmits the force on the shock-absorbing supports to the computer through a data cable. The computer calculates the electromagnetic force required to counteract the force on the shock-absorbing supports, outputs a signal to the control module of the electromagnetic coil 6, the electromagnetic coil is energized, and controls the current parameters according to the required electromagnetic force magnitude. The electromagnetic coil 6 generates an induced electromotive force, thereby generating an electromagnetic force opposite to the relative movement direction of the force on the shock-absorbing supports, counteracting the force on the shock-absorbing supports, and the disc spring 7 and the helical spring 3 undergo elastic deformations, enabling the system to reach a balanced state. To enable the system to reach a balanced state, the pressure sensor 1 monitors the vibration conditions of the support top plate in real time and externally feeds back to the computer 9, and the computer calculates the electromagnetic force of each electromagnetic coil 6 respectively, realizing the active control of the vibration of the oil and gas module process motor.
