Characteristic Analysis of KG18-JZ-K5I Speed ​​Switch Product
Ching Ming Festival holiday notice:
Colleagues and colleagues, in order to make it easier for various departments to arrange holiday production and other related work as soon as possible, we hereby notify you of the specific arrangements for the holidays for the Qingming Festival.
April 5, 20018 - April 6, 2018, holiday for two days. It will work normally on Saturday, April 7, 2018 and Sunday, April 8, 2018.
During the holidays, all departments must do a good job in various tasks:
(1) Strengthen the leaders of safe production and other work during the holiday season, strengthen supervision and management, implement various safety measures, and ensure safe production during the holiday season.
(2) It is necessary to do on-duty and security work during the holiday season, strictly on-duty systems, and to have leadership with the class, duty system, on-duty personnel must fulfill their duties, encountered major problems and emergencies, must be the first time to their superiors Please report the report and handle it properly without delay.
(3.) Before leaving the company, do a good job in the dormitory to cut off water, power off, close the doors and windows, lock the door and other related safety work to prevent unsafe accidents.
(4) Be sure to pay attention to safety when going out to play. I wish you all a pleasant holiday!

product description;
Speed ​​switch (commonly known as low-speed switch, speed switch, also known as the rotation sensor, slip protection device). This product can effectively and timely handle the electrical and mechanical faults such as stall, spin, overload, slow turn, belt slipping, drive chain (band) fall off, drive shaft breakage, etc. that often appear in motors and mechanical transmission devices. Can play a role in ensuring production and maintenance of equipment.
KG18-JZ-K5I speed switch (speed sensor) use
Widely used in steel, electricity, chemical, cement, coal, metallurgy, building materials, mining, port terminals, grain warehouses and other industries using conveyor equipment.
working principle
The speed switch is installed next to the driven shaft and the detection shaft is mounted on the shaft. When the motor is running, the driven shaft is driven to rotate by the transmission device, and the detection piece on the driven shaft also rotates accordingly. The rotation detector receives the even interval pulse signal of the detection piece. At this moment, the rotation detector is in the closed state, and the AC contactor is sucked by connecting the self-protection contact of the intermediate relay (see FIG. 3). The main contact of the AC contactor is closed. Turn the motor. When the equipment is stuck, locked rotor, belt slipping, transmission belt off failure, the transmission shaft will slow or stop, at this time the test piece will also slowly turn or stop, RD-II type rotation detector will not receive Evenly spaced pulse signals to the detection plate. In the specified period of time (5 seconds), no rotation signal is received. The rotation detector will be turned from closed to open, the intermediate relay will be disconnected, the AC contactor will be disconnected and shut down in time, and reliable protection equipment (this product will receive the test piece) The rotation signal has nothing to do with the size of the motor.
KG18-JZ-K5I speed switch main features:
1, intelligent, integrated structure, free setup, debugging, simple installation. The response is quicker when replacing an ordinary rotation detector.
2, non-contact detectors, no moving parts, no wear, long life safety, low maintenance costs.
3, two-wire system, relay (or contactor) as a load, can provide isolated passive contact signal to the computer; can also be directly connected in series in the contactor's self-protection contacts for device protection. The relay (or contactor) pulls in during normal rotation.
4. The DH-A slip switch has a wide power supply range and strong drive capability. It can directly drive contactors within 40A.
5, with a status indicator. The indicator is "flashing" when the device is operating normally; the indicator is "on" when it is slowly turned or stopped
Belt slip detection device, slip switch, slip detector, under speed switch, speed detector, belt stall monitor. Skid detection device, skid detector, skid switch New device for linear detection of conveyors, real-time detection of belt speed. It has been widely used in tapes in conveyor systems, providing a reliable operation for the safe operation of belt conveyors. testing method

KG18-JZ-K5I Speed ​​Switch Installation Instructions:
The fixed bracket is first welded to the cross beam of the conveyor; the arm is then connected to the bracket with a pin and a split pin.
After installation, the following requirements should be met:
Slip detection device tape running direction to prevent, touch the wheel from the tape edge 200-300mm
The distance between the sensing surface and the switch gate is preferably 4mm. The sensing point may be the protruding (face) portion (iron type) at the driven wheel, and the concave surface may also be used as the sensing surface. If there is no uneven surface on the side of the driven wheel, a 7mm thick iron plate can be welded on the inner frame of the driven wheel as the sensing surface. Sensing surface area must be larger than the switch sensing surface (factory configured sensing surface)
Note: Some conveyor driven wheels cannot be installed. The installation can be that the tape is tightly connected and no tape or spinning wheel can run out of the tape during the running of the tape. Some installation locations may require on-site production of mounting brackets. In special cases, if it is necessary to adjust the speed of the switch from a new point, after the switch is installed, start the transport. Under the normal speed of the conveyor, adjust the open potentiometer internal potentiometer counterclockwise to adjust the action indicator.
We can't produce water. We're just the porters of nature.
