Note: Shrinkfitting a steel mud pump liner
Objective:
Shrink fitting a steel liner into a cylinder to create a mud pump liner used in the oil industry
End Product:
mud pump
Equipment:
Ambrell 250 kW, 10 kHz induction heating system, equipped with a remote workhead containing one 53.6μF capacitor. An induction heating coil designed and developed specifically for this application.
Materials:
Steel cylinder 10.625” (27cm) OD with a 2.625” (6.6cm) thick wall and 21.75” (55.2cm) long, liner 5.5” (14cm) OD and 26.375 (67cm) long
Temperature:
900 ºF (482 ºC)
Frequency:
7.8 kHz
Testing:
An eleven-turn helical coil is used to heat the cylinder. The cylinder is placed inside the coil and power is applied for 10 minutes to reach the temperature of 900 ºF (482 ºC). Once the temperature is reached the steel liner slides easily into the cylinder and the assembly is cooled to create the shrink fit
Benefits:
Induction heating provides:
-
Faster heat cycle
-
Increases production rate versus furnace systems
-
No preheat cycle or controlled cooldown required, reduces energy cost
-
Even distribution of heating
