Water ring vacuum pump maintenance and daily maintenance

1. Water ring vacuum pump maintenance

(1) Should always pay attention to the oil level and the cleanliness of the oil, the new pump work 150 hours to change the oil once, after every 2-3 months to change the oil once. If the use conditions are not good, when the vacuum drops, the oil change time can be shortened.

(2) The pump and pump room should be kept dry and clean.

(3) Often pay attention to the temperature of cooling water and oil, the maximum shall not exceed 85 ° C, the inlet temperature of cooling water shall not exceed 30 ° C, the outlet temperature shall not exceed 5 ° C, and the water quality shall be kept clean.

2. Precautions in daily maintenance

(1) Regularly check whether the water ring vacuum pump pipeline and joints are loose. Turn the water ring vacuum pump by hand to see if the water ring vacuum pump is flexible.

(2) Add bearing lubricating oil to the bearing body, observe that the oil level should be at the center line of the oil target, and the lubricating oil should be replaced or supplemented in time.

(3) Screw the water guide plug of the water ring vacuum pump pump body to inject water (or pulping).

(4) Close the gate valve of the outlet pipeline, the outlet pressure gauge and the inlet vacuum gauge.

(5) Click the motor and see if the motor steering is correct.

(6) Start the motor, when the water ring vacuum pump is running normally, open the outlet pressure gauge and the inlet water ring vacuum pump, and gradually open the gate valve after it shows the appropriate pressure, while checking the motor load.

(7) Try to control the flow rate and head of the water ring vacuum pump within the range indicated on the label to ensure that the water ring vacuum pump operates at the highest efficiency point in order to obtain the greatest energy saving effect.

(8) During the operation of the water ring vacuum pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the maximum temperature shall not exceed 80C.

(9) If the water ring vacuum pump is found to have abnormal sound, immediately stop and check the cause.

(10) When the water ring vacuum pump is to stop using, first close the gate valve, pressure gauge, and then stop the motor.

(11) Water ring vacuum pump in the first month of work, after 100 hours to replace the oil, after every 500 hours, oil change once.

(12) Often adjust the packing gland to ensure that the drip in the packing room is normal (it is appropriate to drip out).

(13) Regularly check the wear of the shaft sleeve, and replace it in time after large wear.

(14) When the water ring vacuum pump is used in the cold winter season, after stopping, it is necessary to unscrew the water plug in the lower part of the pump body to put the medium away. Prevent frost cracking.

(15) If the water ring vacuum pump is out of service for a long time, it is necessary to completely disassemble the pump, dry the water, coat the rotating part and the joint with grease, and store it properly.
