Embodiment Construction
[0020] Such as figure 1 As shown, the present invention will be further described below through specific embodiments.
[0021] A multi-motion unit linear motor-driven plunger pump consists of two parts: a mechanical system and an electrical control system. The mechanical system mainly includes integrated distribution valve 1, cylinder body 2, plunger 3, end ball bearing 4, linear motor 5, cylinder barrel 6, cylinder barrel support flange 7, base 12, and cylinder body support base 13. The electrical control system mainly includes servo controller, driver, acquisition card, industrial computer, position feedback device, water cooler, etc.
[0022] The multi-motion unit linear motor-driven plunger pump consists of eight sets of linear motor units 5 arranged in two layers, each linear motor is driven by a corresponding driver, and the servo controller outputs control signals with a certain phase difference to the eight drivers. Thus, the linear motor mover is driven to drive the...
