Thrust section wear preventor
View Patent ↗A thrust section for use above a motor preferably includes a housing, a thrust shaft, a thrust runner connected to the thrust shaft, a thrust bearing connected to the housing, and a motor lead guard. The motor is preferably positioned above a pump assembly. The thrust runner and thrust bearing prevent upward movement of the shaft.
1. A thrust section for use above a motor, wherein the motor is positioned above a pump assembly, the thrust section comprising:
a housing;
a thrust shaft;
a thrust runner connected to the thrust shaft;
a thrust bearing connected to the housing;
a motor lead connector; and
a motor lead guard configured to protect the motor lead connector against contact with the thrust shaft.
2. The thrust section of claim 1 , wherein the thrust section is adapted to connect between a coiled tubing connector and the motor.
3. The thrust section of claim 1 , wherein the motor comprises a motor shaft and wherein the thrust shaft is coupled to the motor shaft.
4. A submersible pumping system comprising:
a motor;
a power cable connected to the motor;
a pump assembly below the motor;
a seal section between the pump assembly and the motor; and
a thrust section above the motor.
5. The submersible pumping system of claim 4 , wherein the thrust section comprises:
a housing;
a thrust shaft;
a thrust runner connected to the thrust shaft; and
a thrust bearing connected to the housing.
6. The submersible pumping system of claim 4 , the thrust section further comprising a motor lead connector that connects the power cable to the motor.
7. The submersible pumping system of claim 4 , the thrust section further comprising a motor lead guard.
8. The submersible pumping system of claim 4 , wherein the thrust protector is adapted to connect between a coiled tubing assembly and the motor.
9. The submersible pumping system of claim 4 , wherein the thrust shaft is coupled to a shaft in the motor.
10. A submersible pumping system comprising:
a motor having a motor shaft;
a pump assembly below the motor; and
a thrust section above the motor, the thrust section comprising:
a thrust shaft;
a thrust runner connected to the thrust shaft;
a thrust bearing connected to the housing;
a motor lead connector; and
a motor lead guard configured to protect the motor lead connector against contact with the thrust shaft.
11. The submersible pumping system of claim 10 , wherein the thrust section is adapted to connect between a coiled tubing connector and the motor.
12. The submersible pumping system of claim 10 , wherein the thrust shaft is coupled to the motor shaft.
13. A submersible pumping system, comprising:
a motor;
a pump below the motor;
a seal section between the motor and the pump; and
means for protecting the motor from up thrust.
