A tube injector with servo electric direct drive to quickly absorb and spray anti-corrosion coating

Abstract

A tube type ejector with the function of quickly sucking and spraying anticorrosive paint through servo electrical direct drive comprises a motor stator, wherein the motor stator is electrified to make a motor rotor move, the motor rotor can drive the long shaft of a linear motor to carry out reciprocating motion upwards or downwards so as to drive a piston to move in an ejection tube; the movement speed of the motor rotor can be controlled by controlling the voltage and the current, servo electrical direct drive can be realized, and therefore, it is realized that the ejection speed is adjustable; in addition, the ejection amount and the ejection distance can be controlled by controlling the movement output force of the motor rotor; when the motor rotor moves upwards, the anticorrosive paint can only be ejected out through a multi-hole cover after passing through a second check valve, and the process of spraying the anticorrosive paint is completed; and when the motor rotor moves downwards, an anticorrosive paint chamber will suck the anticorrosive paint from a paint storage through a first check valve and a flow sensor, and the process of sucking the anticorrosive paint is completed. The tube type ejector with the function of quickly sucking and spraying anticorrosive paint through servo electrical direct drive has the advantages of being controllable in ejection amount and ejection speed, simple in structure, easy and convenient to operate and the like.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion paint sprayers, and in particular relates to a tubular sprayer capable of rapidly sucking and spraying anti-corrosion paint with a servo electric direct drive. Background technique [0002] In recent years, marine strategy has become one of the basic strategies for national development. Some emerging marine projects such as offshore facilities, coastal and gulf structures, and offshore oil drilling platforms have also developed rapidly. For military equipment, such as aircraft carriers and large warships, it has also become the key content of the development of national military basic equipment. For these offshore installations, one of the key issues is the anti-corrosion technology of the equipment casing. [0003] Spraying the anti-corrosion coating on the equipment shell is one of the conventional anti-corrosion methods, which has become an important direction of anti-corrosion technol...

AI Technical Summary

Problems solved by technology

[0005] 1. Relying on air spray coating, it is easy to mix the dirt in the air into the anti-corrosion coating, which reduces the anti-corrosion ability of the coating

[0006] 2. The injection speed is uncontrollable, and it is impossible to implement different injection speeds for different anti-corrosion areas

[0007] 3. The injection volume is uncontrollable, and it is impossible to use different injection volumes for different anti-corrosion areas

[0008] 4. Complex structure and complex operation

[0009] 5. The spraying distance is short and can only be sprayed at close range
