Embodiment Construction

[0021] Such as figure 1 As shown, the present invention will be further described below through specific embodiments.

[0022] 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.

[0023] 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...

Abstract

The invention discloses a linear motor driving type plunger pump provided with multiple motion units. When a servo controller drives a linear motor to reciprocate in a special motion plan, plungers at one end are in water absorption working conditions, a suction valve in a corresponding integrated flow distribution valve is opened, and fluid is sucked into working medium from a total water suction pipe of a system through a flow guiding channel inside a cylinder body; and plungers at the other end are in a water discharging working condition, a delivery valve in the corresponding integrated flow distribution valve is opened, and the fluid is discharged from the working medium from a total water outlet pipe of the system through the flow guiding channel inside the cylinder body. When multiple linear motor motion units are in coordinated operation, the linear motor motion units respectively operate by being staggered for 90 degrees in phase difference according to a triangular wave motion curve, so that formed combined flow of the system can reach a stable value. The linear motor driving type plunger pump system is applicable to a hydraulic system with seawater, freshwater, mineral oil and the like as a working medium and has a broad application prospect in the fields of naval vessels, deep sea exploration and the like.

Description

technical field [0001] The invention relates to a multi-movement unit linear motor-driven plunger pump, belonging to the pump category, suitable for hydraulic systems using seawater, mineral oil, etc. as working media, and has broad application prospects in the fields of ships, deep-sea exploration, and the like. [0002] technical background [0003] With the enlargement of ships and the diversification of ship functions, especially for the special working conditions of military ships, the operation vibration and vibration resistance performance of ship hydraulic pumps, small mechanical noise and fluid noise, and sufficient shock resistance , good corrosion resistance and abrasion resistance, reliable sealing structure and sealing performance have put forward special requirements. [0004] At present, the most common hydraulic pump structures used on ships are axial piston pumps and crankshaft-connecting rod piston pump structures driven by turbine-worm reducers. However, t...
