Hehe, we are peers, can you look at this line?

Operation and maintenance procedures for cleaning sewage pumps.

Operation method of sewage cleaning pump.

Before starting the sump pump, check that the lubricating oil is above the center line of the oil window, and the outlet valve should be closed.

Start the no-load operation of the pump first, and then open the water inlet valve, and then open the outlet valve.

When shutting down, turn off the motor first, then close the outlet valve, and finally close the water inlet valve.

When the sewage pump is working, the bearing temperature should not exceed 60. It is strictly forbidden to touch the rotating part with your hands.

Sewage pump maintenance method.

When the water dripping at the sealing of the packing exceeds 30 drops per minute, it should be added in time, and the leakage of the sewage pump should be replaced in time to replace the skeleton seal.

When the oil level of the check oil window is lower than the center line 1 2, lubricating oil should be added. 32 oil in winter and 68 oil in summer.

Always check that the motor shaft is concentric with the pump shaft.

Protective cover (net) should be added to the coupling

Check the protective net cover of the equipment, and the anchor bolts must be tightened without loosening.

The following people of maintenance have already said, if your sewage pump is controlled by frequency conversion, I can say that the pump controlled by frequency conversion also has a soft starter, it has achieved smooth starting, reducing the impact of the motor pump, prolonging the life of the motor and water pump, avoiding the water hammer phenomenon in the traditional common water, in addition, if you use frequency conversion control, it has undervoltage, overpressure, overcurrent, overheating protection, in fact, I think that many problems of the frequency conversion control pump will appear on the display of frequency conversionIf there is a frequency conversion, he will set up automatic inspection for you, regular pump change, fault self-diagnosis, motor regular rotation, dormancy and other multi-functions, you just need to see if the motor is hot from time to time, whether there is an abnormal sound, whether the pipeline pressure is the same as usual, you can do it.

Nantong Shipping Vocational and Technical College.

Pump room management system.

1. Running duty.

i. Conduct regular pump room inspections every week

1) Whether the electrical switches and wiring screws are heated;

2) Observe the water supply pressure and running sound;

3) According to the water supply situation, adjust the starting force of the pump in time to ensure the normal water supply.

2. Maintain the control valves once a month.

1) Add butter to the gong rod of each valve to keep it bright and rust-free.

2) Each valve must be operated evenly when moving, and it is strictly forbidden to operate by punch.

3) After the maintenance is completed, carefully check whether the switch position of each valve is correct and whether the water supply is normal.

2. Duty records.

The staff on duty shall make detailed records of the operation of water pumps, fire pumps and water supply pressure.

3. Annual inspection and maintenance.

l Carry out anti-rust treatment for indoor and outdoor pipelines.

2. Carry out indoor and outdoor maintenance of the pump house.

Fourth, the reporting system.

1. Report daily inspection and maintenance to department leaders every month;

2. Report to the department leader in time in case of equipment failure.

I also have jurisdiction over more than 200 pumps, and I don't understand what you mean. For machinery, there are several procedures: operation procedures, inspection procedures, maintenance procedures, and lubrication procedures.

There are no maintenance procedures. In the middle of the regular addition of packing, what age, the clean water pump with packing is OK, the sewage pump with the tray is not good. It's also important to see how high your revs are.

Hello, daily maintenance general content. 1. The water distribution gate and pump gate valve open flexibly and do not leak. 2. The indication of each instrument such as the pressure gauge is correct.

3. The uranium bearing temperature of the water pump is not higher than 70 of the collapsed cherry blossoms. 4. The pump runs smoothly without obvious vibration and noise. 5. The connecting screws are tightened without loosening.

6. Whether the temperature of the Mingmeng pump motor is normal. 7. Check whether the mesh cover is intact for all kinds of sewage pumps and sand discharge pumps in the underground, and must be checked once a day, and the mesh cover should be dealt with in time if it is found to be damaged.

Hello dear, Precautions for the maintenance of the pump disorder: first.

1. The water pipeline must be highly sealed, and check whether the link between the pump and the water pipeline is loose or not. Clause.

Second, the bearing lubricating oil should be added to the bearing body to observe that the oil level should be at the center line of the oil standard, and the lubricating oil should be replaced or replenished in time. After 500 hours of operation of the oil-immersed water pump, the sealed oil should be replaced. The oil in the motor cavity of the water pump should also be changed once a year.

4. Close the gate valve of the outlet pipeline of the pump, the outlet pressure gauge and the inlet vacuum gauge. Clause.

5. Jog the pump motor and try to see if the pump motor is turned correctly. Start the pump motor, when the pump is running normally, open the outlet pressure gauge, if the pressure is suitable, gradually open the gate valve, and check whether the pump motor has a load. Clause.

6. Try to control the flow and head of the pump within the indicated range to ensure that the pump runs at the highest efficiency point, so as to obtain the greatest energy-saving effect. Clause.

7. During the operation of the water pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the maximum temperature shall not exceed 80C. Clause.

8. If you find that the pump has abnormal sound, you should stop it immediately to check the reason. Before stopping the pump, the gate valve and pressure gauge should be closed before the pump motor can be stopped. Clause.

9. Adjust the packing gland frequently to ensure that the drip in the packing room is normal. Clause.

10. Regularly check the wear and tear of the pump shaft sleeve, and replace it in time after the wear is large. Clause.

Ten. 1. If the pump is out of use for a long time, it is necessary to disassemble the pump, wipe off the water, coat the rotating parts and joints with grease, and store them properly. Clause.

Ten. 2. The lubrication of the mechanical seal should be clean and the particles of the non-solid Yuchai file body. It is strictly forbidden for mechanical seals to work in dry grinding conditions. Clause.

Ten. 3. Before starting, the pump motor should be coiled several times to avoid breaking and damage to the sealing ring caused by sudden starting. Clause.

Ten. Fourth, the pump cannot be operated for a long time in the cavitation state. Be sure to prevent the pump from rusting: when the pump is not in use, it should be wiped clean and placed in a ventilated and dry place. If the surface of the electric water pump is damaged and the paint is removed, the rust should be removed in time and the anti-rust paint should be applied to protect it. Clause.

Ten. 5. It is forbidden for the pump motor to run for a long time when the flow rate is running. Regularly check the operation of the pump, and the pump motor is running for a long time with overcurrent. Clause.

Ten. 6. The pump should be supervised by a special person during operation to avoid accidents. Clause.

Ten. 7. The bearing should be refueled every 500 hours of operation of the water pump. The power of the water pump motor is more than 11kw, and it is equipped with a refueling device, which can be directly injected with a high-pressure oil gun to ensure excellent bearing lubrication. Clause.

Ten. 8. After the long-term operation of the pump, when the noise and vibration of the unit increase due to mechanical wear, it should be stopped for inspection, and the vulnerable parts and bearings can be replaced if necessary.

Ten. Nine, do a good job of comprehensive maintenance of the pump generally every two years, to carry out a comprehensive maintenance, the worn parts and poor sealing performance of the components, can be repaired, can not be repaired to all replace, can not be reluctantly used, so as not to bring serious consequences. Hope my answer is helpful to you, <>
