1, understand the operation process, the concentration of the suspension or material, size, number, quality process requirement.
2, the density of familiar with this position and working principle of the control device for the electric basic knowledge.
3, master the related to this position of medium suspension, related equipment maintenance method, and with basic skills to practice for a simple testing.
4, master this position equipment, open, downtime procedure and time, and failure of the inspection, analysis, prevent and eliminate method.
5, the master this post slurry pump vibration technology, inspection, analysis, prevent and troubleshooting methods.
6, before driving to make the following checks: slurry pump
Check the incoming barrels (pool) in the upper level and incoming screen should be in good condition is not blocked, all parts should be complete, no loose fall off; Whether the lubrication situation of oil is enough, oil well and Shu net, good seal water supply.
7, should first before driving pulley or coupling at least one revolution of the human, such as transfer, it is forbidden to drive.
8, slurry pump pump application, first open seal after water drive motor.
9, slurry pump start normal, the electric current shall not exceed the rating.
10, pay attention to the voice of the motor, vibration, temperature conditions. Pay close attention to bearing and the bearing lubrication condition, found the problem to solve in time.
11, pay attention to the working principle of the seal water supply guarantee.
12, packing to elastic, tight cause overheating or even smoke too loose is leaking, washed out. Suitable firmness to drop 1 ~ 20 drops per minute is advisable.
13 and close contact with related jobs and cooperate, in accordance with the requirements of process control well the right line of shoes.
14, found that when the line capacity is insufficient, should check: triangle is too loose, blade and guard plate gap is too big; Impeller, packing whether excessive wear; Seal water adequacy, found the problem to the stop.
15, parking, for mechanical and electrical equipment and pipeline, valve inspection, found that exception handling in a timely manner.
16, pay attention to check the working condition of packing, leakage should be replaced, add a new packing, to ensure the quality of work, to play the working efficiency of the pump.
17, the use of parking time for equipment maintenance, deal with problems arising from the operation.
18, sanitary equipment and the environment, to do a good job of succession. |
