Introduction to maintenance and repair measures for arc gear pumps

1. There is no looseness in the arc gear pump piping and joints. Turn the YCB series arc gear pump by hand to see if the YCB series arc gear pump is flexible.
2. Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the center line of the oil mark. The lubricating oil should be replaced or replenished in time.
3. Unscrew the water plug screw of the arc gear oil pump body and pour water (or grout).
4. Jog the motor and see if the motor is turning correctly.
5. Start the motor. When the YCB series arc gear pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. After the appropriate pressure is displayed, gradually open the gate valve and check the motor load.
6. Try to control the flow and head of the YCB series arc gear pump within the range indicated on the sign to ensure that the YCB series arc gear pump runs at the highest efficiency point to obtain the maximum energy saving effect.
7. During the operation of the arc gear pump, the bearing temperature should not exceed the ambient temperature of 35C, and the maximum temperature should not exceed 80C.
8. If you find that the arc gear pump has abnormal sound, stop it immediately and check the cause.
9. When the arc gear oil pump is to be stopped, first close the gate valve and pressure gauge, then stop the motor.
10. During the first month of operation, the arc gear pump will change the lubricating oil after 100 hours, and then change the oil once every 500 hours. 12. Frequently adjust the packing gland to ensure that the drip leakage in the packing chamber is normal (to drip) It is appropriate).
11. Regularly check the wear of the bushing, and replace it when it is worn out.
12. When the arc gear pump is used in the cold winter season, after parking, the screw plug of the lower part of the pump body should be unscrewed to release the medium to prevent freezing cracking.
13. The arc gear oil pump is to be deactivated for a long time. It is necessary to disassemble the pump completely, dry the water, and apply the grease to the rotating parts and joints, and keep them in a safe place.
