Aiming to reduce the time to load a roll to the minimum point, this Double Head Decoiler type drives one of the rolls, as the other one waits as a backup.
When the driven roll is over, the backup roll will be ready to be connected to the driver within a very short period of time. When you connect the new roll to the driver, you will have a long time to load another spare roll. Double head Decoiler is an ideal solution for production plants where production speed and continuity are crucial in serial manufacturing. So usually configured with the S loop straightener, high speed gear machine and H Frame High Speed Press Machine, it`s usually suitable for motor rotor and stator lamination stamping.

Application of explosion-proof switch 
Explosion-proof switches are mainly used in a variety of applications that require a safe, reliable, and easily disconnectable connection. This is especially true for machines and systems that are prone to deflagrable gases, as well as for powering systems; also used in the petrochemical industry; including mills, granaries, paint or ink manufacturers, wood processing plants, cement plants, shipping and sewage treatment.
Explosion-proof switches are also suitable for external electrical equipment, such as motors, pumps, lighting equipment, process control devices used in hazardous manufacturers and factories, or explosive atmospheres that cause flammable gas, vapor, mist gas, or combustible dust.
The above is the introduction of the features and applications of explosion-proof switches. Everyone can find out. Explosion-proof switches are commonly used in the coal mining industry, paint or ink manufacturers, wood processing plants, cement plants, shipping and sewage treatment.
Explosion-proof switch installation method Connect the multimeter to the output lead.
Unscrew the screw on the top of the controller.
The positive and negative pressure difference is added to 0.15 MPa, which can be read from a standard pressure gauge.
Loosen the set screws.
Use a flat-blade wrench and turn the set point clockwise to adjust the hexagonal groove of the screw so that the set value will become small until the switch contact switches at 0.15 MPa.
Adjust the pressure of the calibration table back and forth at 0.6MPa, and check whether the pressure is 0.15Mpa. This value is the lower switching value to be set. Its corresponding upper switching value is between 0.16-0.17MPa.
Tighten the set screws.
Commissioning is complete.
The above is the introduction of explosion-proof switch installation method, we can find out. Explosion-proof switch is mainly used in metallurgy, chemical, petroleum, steel, machinery, refrigeration equipment, refrigeration equipment, water pump differential pressure control, low water level protection differential pressure control, power plants, cement, food, shipbuilding and other industries of gas, steam and water, Oil pressure and other liquid pressure equipment and other industrial equipment supporting agencies, pressure monitoring, alarm, interlock protection, to achieve two automatic control.
