To accurately measure the speed, the drive shaft of the sensor head must be connected to the tail roller shaft via a coupling, ensuring that the drive system rotates in sync with the tail wheel. The speed sensing head is mounted on the tail wheel frame. If belt speed detection is required, a contact wheel should be added to the drive shaft of the speed sensing head, which will rotate along with the conveyor belt. In this case, the speed sensing head should be installed on the beam of the conveyor belt.
It is recommended to use a three-core shielded cable between the sensor head and the protection control box to enhance the detector’s resistance to electrical interference. Additionally, both ends of the cable must have a one-to-one correspondence; otherwise, the system may not function properly. The field equipment control box and the slip protection control box are connected using a four-core cable. Two of the cores are for power supply, while the other two are for relay normally open contacts. These lines must be clearly labeled to prevent miswiring. Once the wiring has been verified as correct, the system can be safely put into operation.
During the operation of the pump, serious failures such as “key rolling,†impeller nut detachment, or even shaft breakage often occur. This is typically caused by corrosion of the carbon steel key in a brine environment, leading to relative rotation between the shaft and the impeller, resulting in severe wear of the impeller hub. The fit between the impeller and the shaft does not meet the required technical specifications. Some impellers are so worn that they have reached the end of their service life.
To address these issues, we have implemented the following maintenance measures. First, we replaced the carbon steel key with a stainless steel key to improve corrosion resistance. For impeller repairs, we used a hub on the rear cover of the impeller. The left-side hub was pressed onto the shaft, and the shaft hole was enlarged to match the outer diameter of the impeller wheel. The front end of the titanium wheel sleeve, which includes a shoulder, should be sized according to the mating length between the impeller and the shaft. The length of the rear cover should be equal to the length from the wheel to the hub, ensuring proper alignment and structural integrity.
