Description

Technical Field

[0001] This invention belongs to the field of motor interlocking protection technology, specifically relating to a motor interlocking protection device for quantitative control of vibration displacement. Background Technology

[0002] Currently, the mud produced during the brine purification process in brine making adopts a relatively advanced reinjection process into the well cavity. This involves using a plunger mud pump to pressurize the mud and inject it into the well cavity. These mud pumps originated from the oil drilling industry and have high requirements for the particle size of the feed mud. Due to factors such as process materials and equipment maintenance, the mud pump's operating conditions become unstable, leading to increased vibration at the power transmission end, reduced bearing and transmission gear life, and in extreme cases, major accidents such as broken teeth or broken shafts.

[0003] Currently, through inspection and analysis, major accidents are caused by poor feeding and impurities getting stuck in the flow components, resulting in high and low voltage phase crosstalk, which in turn causes a sharp increase in vibration at the power end. In severe cases, it can cause the crankshaft cover bolts to break, and the main shaft and driven crankshaft gears to disengage and make contact. During this period, the motor continues to run without interlocking to stop, which is extremely dangerous. It is not convenient to use interlocking to stop the main motor when the vibration continues to increase to a certain value to prevent extreme accidents. Summary of the Invention

[0008] When using the motor interlock protection device for quantitative control of vibration displacement using this technical solution, the drive motor is started to drive the crankshaft transmission disc to rotate. The crankshaft transmission disc is limited in rotation by the setting of the limit component.

The start and stop of the drive motor are controlled by the sensing component and the positioning component. External equipment is connected by the setting of the external component, and vibration is reduced by the setting of the vibration damping component. This makes it easy to stop the main motor through interlock when the vibration continues to increase to a certain value, thus preventing extreme accidents.

The arc-shaped rail is engaged with the arc-shaped groove, and a fixing screw is provided inside the arc-shaped rail.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The motor interlock protection device for quantitative control of vibration displacement of the present invention utilizes a start-up drive motor to drive the crankshaft transmission disk to rotate. The steel balls are limited by the setting of the partition plate, and the rotation of the crankshaft transmission disk is limited by the setting of the steel balls. When the crankshaft transmission disk rotates, it generates vibration, which is transmitted to the limiting ring. The position of the limiting ring is fixed by the setting of the upper pressure plate and the lower pressure plate. When the limiting ring vibrates, it is sensed by the mutual contact between the pressure block and the second micro switch. The lower pressure plate is installed and limited by the setting of the arc rail. The other end of the vibration is sensed by the setting of the same first micro switch. The first micro switch and the second micro switch are connected by the setting of the connecting wire. The arc rail is stably installed by the setting of the fixing screw. The sensing of the first micro switch and the second micro switch controls the start and stop of the drive motor, so that when the vibration continues to increase to a certain value, the main motor is stopped by interlocking to avoid extreme accidents.
