⊙ Before use:
1. The selection is correct. The use factor is greater than the condition factor.
2. The installation type is correct.
⊙ In use:
1. Ensure that the vent plug is unobstructed.
2. Operate according to the operating rules, especially the supporting use of the manual is very important.
⊙ After use:
Normal maintenance, timely oil change, keep the environment clean and so on.
Second, what are the precautions for filling lubricants?
1. The product has been filled with lubricating oil at the time of shipment. Please refer to the "Product Instruction" and other random data for oil change and refueling.
2. In order to ensure the quality and effect of lubrication, we recommend the use of imported brands of lubricants when changing the lubricant. For specific grades, please refer to the chapter “Lubricants and Lubricants†in the product manual.
3. Before starting the machine, remove the red plastic plug on the vent plug to ensure smooth discharge of the product and reduce product leakage.
4. The amount of oil can be observed from the oil mirror. The correct oil level should be after the stop cooling. The oil level is in the middle of the oil mirror. Too little lubricating oil will cause the internal parts of the product to accelerate wear; too much lubricating oil will cause the product operating temperature to be too high.
5. Observe that the oil level must be at shutdown and at ambient temperature.
6. Lubricants must not be mixed. Two different grades of lubricants can cause lubricants to react chemically. They can even precipitate, destroy their lubricating properties and affect the service life of the reducer.
Third, why should we remove the rubber seal plug on the vent plug?
During the operation of the transmission product, heat is generated, which causes the oil temperature in the body to rise, the gas to heat and expand, and a certain pressure inside the body. Under normal circumstances, this pressure will be released through the vent plug, if the vent plug is not smooth, it will cause the pressure to rise continuously, so that the oil seal parts and other sealing weak links produce oil leakage, so unplug the rubber sealing plug is very important.
Fourth, the motor frequency is too low will bring what disadvantages?
1. For an ordinary motor, if the frequency is too low, the rotation speed of the rotor of the motor will be reduced and the air volume blown by the fan will be reduced (the cooling air volume will be reduced proportionally to the third power of the motor rotation speed), which will cause the motor cooling conditions to deteriorate and the temperature of each part to increase;
2. Decrease in speed will also affect the efficiency of the motor, resulting in a decrease in the output torque, that is not enough force;
3. Since the electromagnetic torque is proportional to the square of the power supply voltage, the starting torque of the motor is not enough, which makes it difficult to start the motor.
4. Therefore, the stator current increases, the power loss increases, the stator windings overheat, and the motor may be burned if the time is too long.
Note: If the frequency is too high or too low, it will affect the function of the motor, increase the copper loss, damage the bearings, and even burn the motor.
Fifth, on the stepless machine in the debugging process, what issues need attention?
1. The pulley (or sprocket) should be moderately tensioned.
2. It is better to run around 80% of the rated current for each period of testing the motor current. Such as 0.75kW (rated current 2.05A) motor current is about 1.6A.
3. Ensure that the operating frequency is around 50Hz. Because the frequency is too low, the power of the motor will be unfavorable and the service life of the motor will be reduced.
4. Speed ​​as much as possible at the minimum speed of 3 times to ensure maximum life.
5. Can not be too much oil, can not be short of oil, can be determined by oil mirror observation.
6. Pull out the red rubber sealing plug to ensure smooth exhaust.
