Technical field
The present invention relates to the pipe mill field, more particularly, relate to a kind of pipe mill Direct Current Governor System.
Background technology
DC motor is divided into two types of separate excitation and self-excitations as the difference of the prime mover in the direct current power dragging system according to its excitation mode.Separately excited DC machine has superior speed adjusting performance, still is widely used in on the higher manufacturing machine of speed governing performance requirement, in manufacturing machines such as large-scale vertical lathe, large-scale pipe mill, pipe mill, drawbench at present.
The variation of the motor speed that separately excited DC machine causes owing to the variation of load in the course of the work is called velocity variations; If load torque remains unchanged, realize the manufacturing machine change in rotational speed by taking artificial measure, be called speed regulation, be called for short speed governing.
The method of separately excited DC machine speed governing generally has several: mechanical means speed governing, electric approach speed governing and the speed governing of mechanical electric fitting method.Mechanical speed governors is realized speed governing by changing the transmission mechanism speed ratio, and electrical speed regulation is then realized speed governing by changing the working point that the electrical control parameter changes the motor operation.The speed governing of mechanical electric fitting method then can come speed governing with better simply electrical control equipment and gear.
In the prior art, what the speed governing of the separately excited DC machine in pipe mill was adopted is the SCR control governing system of resolution element.Because the control point of the Direct Current Governor System of resolution element is many, line length, motor oppositely are abutted against tentaculum and switch, the starting of motor relies on excises high-power resistance step by step and carries out, thus the energy consumption height, unstable properties, the failure rate height, the maintenance cost height can not satisfy the production needs.
Summary of the invention
In view of this, the embodiment of the invention provides a kind of non-insulated track circuit analog meter, to realize improving the purpose of debugging efficiency.
The embodiment of the invention is achieved in that
A kind of pipe mill Direct Current Governor System comprises: digital silicon DC speed regulator, programmable logic controller (PLC), photoelectric encoder and optoelectronic switch;
