1. The
deep well pump before cleaning according to the rules to unload parts, check the foreign body inside the pump, record and analysis of existing problems.
2. After the cleaning is completed, the measurement of each part size, analysis of wear.
3. Carefully check the valve ball valve seat with no damage and sealing performance test.
4. Wipe the surface of the pump barrel, if necessary, use emery cloth polishing away surface sediments of the pump cylinder, gauge measuring pump barrel diameter of the gas, such as the diameter difference is greater than 0.05mm should be grinding.
5. On the pump cylinder for linear degree detection, if the excessive, the straightening.
6. Check the plunger diameter and roundness, to determine whether to continue to use.
7. Check all parts of the thread and sealing surface with no damage, to determine whether it can continue to use.
8. Any parts that cannot be used should be stored separately and replaced with qualified parts.
9. After the completion of the assembly of three parts of the piston pump cylinder gap pressure test leak loss, whether it meets the requirements of oil well.
10. To test the strength of the pressure, to check whether the leakage, especially in the case of oil leakage.
11. Above content to evaluate the technical status of
deep well pump, and make a good record.
12. Repair, adjust and replace parts according to the above evaluation results, and record the clearance and valve ball valve seat seal.
13. After the assembly of the plunger pump barrel seal pressure test and pressure test.
