Embodiment Construction
[0036] Such as figure 1 , 4 , The fluid injector shown in 5, 6, and 7 includes components such as a fixed iron core 2, a movable part 3, a valve sleeve 4, a valve seat 5, a spring 6, an elastic cylindrical pin 7, and a filter 8.
[0037] Such as figure 1 , 2 , 3, 5, and 6 show the assembly equipment (9), including the ejector rod 13, the ejector rod seat 14, the lifting motor 15, the lifting displacement platform 19, the rotating motor 24, the displacement sensor 25, the displacement controller 27, etc., the described Lifting motor 15 drives the stroke of lifting displacement platform 19 to be greater than the distance between the lower end surface of movable part 3 and the top surface of push rod 13 when the zero point of displacement sensor 25 is set and the sum of the set lift of movable part 3.
[0038] The position of the top surface of the push rod 13 is lower than the lower end surface of the movable part 3 before the zero position of the displacement sensor 25 is se...
