The service life of slurry pump is a concern of users. The slurry pump is different from other pumps because it mainly transports abrasion slurry, so the service life is much shorter than that of clean pump. Daily maintenance and maintenance can extend the service life of slurry pump. Slurry pump is an important part of mechanical equipment, its daily maintenance is its basic component, is the key to its application. 1. Daily inspection of slurry pump is a necessary condition
The slurry pump equipment should be carefully checked before daily use.
If there are any abnormal conditions in each part of the slurry pump, it shall be checked and registered frequently.
At the same time, you should keep a detailed record of which parts are prone to problems and which parts need to be replaced.
Attention to regular maintenance is the foundation
When using slurry pumps, various problems can occur, resulting in mechanical repair and permanent damage.
These are maintenance problems.
Therefore, the regular maintenance of slurry pump equipment is necessary, and is still strictly implemented by operators.
Training and assessment of slurry pump operators
Once the slurry pump is used, it is necessary to train each operator.
This operation requires that mechanical operations can be performed in the future. This can reduce operational errors and lead to mechanical hazards.
Four criteria for the detailed protection of slurry pump
1. Before closing the pump outlet valve, open the slurry pump inlet valve.
Then start the pump, and then start the pump outlet valve.
The size and speed of the pump outlet valve shall be controlled by the pump without vibration and the motor shall not exceed rated current.
2. Slurry pump is mainly used for conveying flow.
Therefore, the flow meter should be installed in the operation monitoring system to monitor whether the flow meets the requirements at any time.
In a pipe system with a cyclone, a slag washing system, and a pressure filtration and dewatering system, the outlet of the pipe must be under certain pressure.
Therefore, in this system, pressure gauges should be installed to monitor whether the pressure meets the requirements.
3.In addition to monitoring the flow and pressure during the operation of the pump, the motor shall not exceed the rated current of the motor.
4.Monitor oil seal, bearing and other phenomena at any time, and handle them at any time.
The following points should be noted in the maintenance of slurry pump
(1) the water pressure and water quantity of the shaft seal must comply with the regulations, and the filling degree shall be adjusted or replaced at any time, so as to avoid sealing leakage and replace the mechanical seal in a timely manner.
(2) when replacing the bearing, the bearing components must be free of dust and the lubricating oil must be clear. In the operation of the pump bearing temperature is generally not more than 60 ~ 65 ℃, the highest do not exceed 75 ℃.
(3) ensure the coaxiality of motor and pump, ensure the elastic gasket in the coupling is intact and replaced after damage.
(4) ensure the correctness and reliability of the pump assembly and piping system.
(5) some parts of slurry pump are vulnerable parts. In daily operation, attention should be paid to the loss of worn parts, timely repair or replacement, in the slurry pump damaged parts repair or replacement process, to ensure correct installation, reasonable clearance adjustment to prevent failure.
(6) there is no air leakage in the suction pipe system of slurry pump. In the process of operation, attention should be paid to whether there is blockage. The medium transported by slurry pump is solid particles. Therefore, the baffle set in the pump tank should meet the requirements of slurry pump passing through particles. This reduces the ability of large particles or long fibers to enter the pump body. |
