Resistance position switch is called resistance position switch, resistance position meter, resistance position switch, etc. It is a simple and reliable on-site control device, mainly used to detect the position height of physical materials (powders, particles).The series blocking agent level switch has the advantages of unique sealing design, excellent overload protection function and simple installation method. It is widely used in feed, food, pharmaceutical, chemical, plastic, construction, fertilizer and other fields. As a material control instrument, the rotary cut-off position switch has many advantages, but in the process of long-term use, due to the harsh conditions on the site or the improper installation of the staff, it may not be used normally. There are many reasons for the failure, and the specific part of the problem should be investigated. So, how to correctly check the malfunction of the rotary blocking switch?
Problem solving step 1
The rotating material level switch is a material level measuring instrument. It uses a micro motor as a driving device, and the drive shaft is connected to the clutch. When the material is not in contact, the motor works normally. When the blade contacts the material, the motor stops rotating, and the detector outputs a contact signal to cut off the power supply and stop rotating.Generally speaking, the motor is the most important and easily consumed part of the spin barrier switch. The importance of the spin barrier switch is the same as the heart is important to humans. If the quality is not good or an ordinary motor is used, the life of the rotation blocking switch will be shortened. Therefore, if the cut-off position switch fails, first open the cut-off position switch junction box, remove the power cord, turn on the machine and observe the working status of the motor. When the motor fails, usually when the main shaft does not rotate or the main shaft revolves, the motor will make abnormal noises. The only way to solve this problem is to contact the manufacturer and replace with a new motor. Therefore, when the user purchases the resistance switch, it is recommended to choose the resistance switch of the motor with good quality, high reliability and long life, so as not to disappear due to price temptation. (Note:). The motor is very important to the reliability of the spin intercept position switch. Therefore, the series of resistance position switches use imported motors, micro switches and bearings. At the same time, they pay attention to process details, strictly control the production process and quality inspection, and have higher performance than similar domestic products. reliability.Problem solving step 2In step 1, if the motor works normally, check whether the switch output signal is abnormal. After the switch output signal is switched normally, the circuit board damage can be eliminated. When the switch output signal is not converted normally, the circuit board itself may be damaged, and you need to contact the instrument maintenance personnel to send for repair.Problem solving step 3When the spindle and spindle components are inconsistent in size, the spindle card may be blocked. When the spindle card is blocked, the anti-rotation switch is accompanied by the idling echo of the spindle, which is easy to cause false alarms or shorten the life of the instrument. The solution of this fault requires the manufacturer to replace parts of the correct size and assemble them strictly according to the requirements of the engineering documents to ensure that the parts are fully lubricated.Step 4 solve the problemIf there is no abnormality in the meter itself, it should be confirmed whether the on-site installation is reasonable. First of all, confirm whether the hole size of the mounting plate is appropriate. Secondly, check whether the installation spool and hole positions are different, and whether the bottom plate opening is unreasonable.It is hoped that after reading the above steps, if the blocking agent level switch is abnormal, the user can solve the problem by himself to ensure the normal operation of the production.
