The invention provides a screw pump vibration control structure and method. The screw pump vibration control structure comprises a machine body, a screw, a mass balancing device and an acquisition and analysis system; a vibration sensor is arranged on the machine body, and the vibration sensor is used for monitoring vibration of the machine body; the screw is arranged in the machine body in a penetrating manner, the machine body is further provided with a rotating speed sensor, and the rotating speed sensor is used for monitoring the rotating speed of the screw; the mass balancing device is arranged at the vacant end of the screw, and the mass balancing device is used for adjusting the mass of a counter weight; and the acquisition and analysis system is in communication connection with the vibration sensor and the rotating speed sensor. According to the screw pump vibration control structure, whether a screw pump resonates or not can be known through analysis of the acquisition and analysis system, mass adjustment and resonance elimination are carried out by adjusting the mass balancing device at the vacant end of the screw, so that the screw pump reaches a good running state, and the screw pump is more convenient to adapt to the system by adjusting the design of the screw pump.
Description
technical field [0001] The invention relates to the technical field of screw pumps, in particular to a vibration control structure and method for screw pumps. Background technique [0002] The screw pump is a kind of pump that uses the rotation of the screw blade to make the water body spiral upward in the axial direction. Among them, the three-screw pump has a main screw and two driven screws. When the driving screw rotates, it drives the driven screw that engages with it to rotate together. The volume of the screw meshing space at one end of the suction chamber gradually increases, and the pressure decreases. or drive functions. The three-screw pump has the characteristics that the flow rate is basically not affected by the outlet pressure, and is often used as a drive pump for lubricating oil systems with stable flow requirements in ship power plants. [0003] In the prior art, the type of installation base and vibration isolator is generally determined according to the...
