Ask for some knowledge about moving equipment

1. Accelerometer (accelerometer) An instrument that measures acceleration. When an object has a large acceleration, the object, the instruments and equipment it contains, and other objects without relative acceleration are all subject to a force that can produce the same large acceleration, that is, a dynamic load. To know the dynamic load, the acceleration must be measured. Secondly, to know the instantaneous spatial position of aircraft, rockets and ships, the acceleration can be continuously measured through inertial navigation (see gyro platform inertial navigation system), and then the velocity component is obtained through integration operation, and then integrated again to obtain the position coordinate signal in one direction. The instrument measurement results in the three coordinate directions are integrated into the motion curve and give the spatial position of the aircraft at each instant. Another example is that in some control systems, acceleration signals are often required as part of the information required to produce control effects. The problem of continuously measuring acceleration also arises here. A device that can continuously give an acceleration signal is called an acceleration sensor.

2. What does keyphaser do? What are the functions? Key phase, the reference position when measuring vibration. 3.What is a pump-out vane? What are the functions? It should be the outlet guide vane of the pump. 4.What are runaway speed and trip speed, and what is their relationship? The runaway speed is to ensure the maximum speed at which the master motor runs when the slave motor reaches full speed, and the trip speed is the trip speed.

Can it be simpler? What is the function and purpose of this instrument installed on the pump?
