Motor protector (electronic thermal relay) available

ZLDB motor protector (electronic thermal relay) is based on the principle of metal resistance voltage effect to realize various protections of the motor. It is different from the principle of metal resistance thermal effect of thermal relay, and is also different from the core-type motor protector (electronic thermal relay) current transformer. Principle of magnetic effect.

The advantage is

1, the volume is small, easy to achieve interchange with thermal relays.

2. There is no thermal relay which is prone to thermal fatigue and the technical parameters are difficult to recover the initial state. The protection parameters are stable and the repeatability is good.


3, with a variety of protection features and long life and other advantages. Widely used in petroleum, steel, metallurgy, textile, chemical, cement, mining and other industries.

Sharpening Machine is simply a device for cutting tools, a metal cutting tool that is used to trim high speed steel. Some of the tools used to trim cemented carbides and other superhard materials.
The characteristics of sharpening grinder:
The sharpening tool is simple and convenient, and the sharpened blade is in a straight line. Compared with manual grinding, the blade strength is increased, and the service life and processing capacity of the blade are increased. The machine has the fuselage, worktable, slide, reducer composed of six electrode, grinding head, electrical appliances, each part has the advantages of compact structure, reasonable layout and beautiful appearance, smooth cutting grinding processing, suitable for all kinds of straight edge tool!
