Product Description

Product Description

 

Level gauge: Level measurement refers to the detection of the height of materials (solid or liquid level) in closed or open containers during industrial production processes; The instrument that completes this measurement task is called a level gauge. Level gauge, also known as "level gauge", "level gauge", "level gauge" refers to "level gauge", "level gauge", "level gauge", "level monitor", "level monitor", etc. Classification is also known as "level meter" or "material level meter". Continuous level gauge: a level gauge that enables real-time continuous monitoring of the height of material in the silo. Material level switch: a switch that controls the height of the material level in the silo through point measurement. Anti rotation material level switch - threaded type

 

 

Operational principle The working principle is to use a permanent magnet motor to drive the rotation of the blades. When the detected material rises to the position of the blades, the rotation of the blades is blocked, and this resistance is transmitted to the detection device in the junction box. The device outputs a switch signal to the outside and cuts off the power to stop the rotation of the blades. When the material level drops, the blade resistance disappears, and the detection device relies on the tension of the spring to restore to its original state. The spring tension is adjusted for different material densities. When the density is high, the spring tension is adjusted to be strong or strong, and vice versa, it is adjusted to be weak or weakest. Installation precautions 1. The wire inlet of the junction box must face downwards, and the cable fixing nut must be locked tightly. 2. When delivering power, it should be confirmed that the power supply voltage is the same as the voltage marked on the resistance rotary switch. 3. The load of the controlled circuit must match the contact capacity of the resistance rotary switch. 4. The rotary switch should be avoided from being installed under the discharge port to reduce material impact on the blades and misoperation; When unavoidable, protective plates can be installed above the blades. When disassembling and installing the adjustable shaft length resistance rotary switch on site, when connecting the steel wire rope joint to the transmission shaft, the locking nut must be coated with oxygen deficient adhesive and then tightened with a wrench. 6. There should be no toxic gases that corrode aluminum alloys on the installation site.

Torque adjustment 1. Users can adjust the torque according to the specific gravity of the tested material. When the specific gravity of the measured object is high, the spring torque can be adjusted to the strong or strongest position, and the sensitivity of the switch is poor at this time; When the specific gravity of the tested material is small, the tension spring can be adjusted to the weak or weakest position, and the sensitivity of the switch is better at this time. 2. Specific method: Open the junction box, take out the torque spring near the porous end, and insert it into the corresponding hole as needed (the hole near the terminal block has the strongest torque). Note: Do not replace the tension spring casually to avoid misoperation.

NO.	Fault phenomenon	Cause analysis	Troubleshooting
1	When the material reaches, the blades still rotate	The blade size does not match the specific gravity of the material	Redetermine blade size
2	Blade deformation or transmission shaft deformation and bending	The material impact force is too strong	Add protective plates or take other protective measures above the blades
3	Blade does not rotate	1. The power supply is not properly connected  2. Motor burnt out	Check the wiring and connect it properly Contact our company to replace the motor

 

Daily maintenance 1. Check whether the transmission shaft and blades are bent, deformed, damaged or loose. 2. Check if the connection between the drive shaft and the blades is secure. 3. Regularly remove materials and debris from the blades and drive shaft.
