The topological principles of DC circuit breakers are complex and diverse. According to the different key on-off components in DC circuit breakers, DC circuit breakers can be divided into three types: mechanical DC circuit breakers, all solid state DC circuit breakers, and hybrid DC circuit breakers combining mechanical and solid-state switches. DC circuit breakers can also often appear in our lives. In the following, ATO automation will talk about basic information of DC circuit breaker.

Lobe pump is a kind of industrial machinery, which mainly relies on the suction force generated by the rotor when it rotates, and then conveys all the materials that need to be conveyed by different meson to the discharge port by inhalation. Widely used with various industries, lobe pumps can shorten the life of lobe pumps if they are not operated in a standard way during use. The following explains the scope of application and features of the lobe pump as well as precautions for use.

Piston pump from the structure is divided into single cylinder and multi cylinder, its characteristic is relatively high head. The flow rate of the piston pump is determined by the diameter of the pump cylinder, the piston stroke and the reciprocating times of the piston per minute. Piston pump is suitable for conveying oil emulsion without solid particles at room temperature. It is widely used for oil field, coal seam water injection, oil injection, oil production. Chamber press hydraulic press power pump, hydraulic sand, fertilizer plant transport ammonia liquid, etc. If the overcurrent component is stainless steel, corrosive liquid can be transported. In this article, we mainly introduce the definition and application of axial piston pump.

Fiber laser marking machine is a laser with rare earth element doped glass fiber as the gain medium, fiber laser marking machine has become a hot topic in laser physics research in recent years. It is unanimously considered to be a new generation product that has the potential to fully replace solid-state lasers. Fiber laser marker can be developed on the basis of fiber amplifier: the high power density is easily formed in the fiber under the action of pump light, causing the laser working material laser energy level "particle number inversion", when properly added to the positive feedback loop (resonant cavity) can form the laser oscillation output.

Gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically specified conditions, with directional selective reflection properties. The gloss we usually say refers to mirror gloss, so the gloss meter is sometimes called mirror gloss meter. Gloss is quite different from the machining industry's concept of finish or roughness, which is a continuation of the tiny unevenness on a material's surface.

Thermal overload relays are overload relays that apply the principle of current thermal effect and use electrical thermal bimetallic sheets as sensitive components. The electrical thermal bimetal sheet is made by heating and rolling two alloys with large difference in linear expansion coefficient. When heated, the bimetallic sheet bends from the high expansion layer to the low expansion layer. When the current is too large, the element acts due to "heat", so that its linked moving contact cuts off the power supply of the controlled circuit and the protected equipment.

The Diaphragm pump, also known as control pump, is the main type of actuator. It changes the fluid flow with the help of power operation by receiving the control signal output by the adjustment control unit.
