Einleitung
This guide will show you how to pull the riser main from the well using three lifting spanners.
This procedure requires four people: one on each of the lifting arms, and one to control the pipe vise. Communication is very important throughout this procedure. If the person handling the pipe vise opens it before everyone is ready, the riser main could drop through the vise and be lost down the well.
Werkzeuge
-
-
Place the spacer collar around the pump rod below the raised chain, with the beveled side down, and the flat side facing up.
-
-
-
Lift the pump handle until the base of the chain comes to rest on the spacer collar, and the chain is slack. Hold the handle in this position while the chain is being detached.
-
-
-
Using the two access holes, place an angled socket wrench on the bolt and nut attaching the chain to the pump handle.
-
-
-
Remove the two bolts from the handle side of the pump head.
-
Use one wrench on the bolt and another on the nut beneath. Hold the bolt stationary and loosen the nut.
-
-
-
After removing the two handle side bolts, have your partner support the weight of the handle.
-
Remove the two remaining bolts in the same fashion.
-
-
-
Slightly twist the head flange, until the corners overhang the top of the tank far enough to grab.
-
-
-
Unscrew the chain from the top of the pump rod.
-
Remove the chain.
-
Check the chain for signs of wear or damage.
-
-
-
Screw a T-handle onto the top of the pump rod. Tighten the T-handle up against the jam nut.
-
-
-
Remove the four bolts connecting the tank to the top flange.
-
Use one wrench on the bolt and a second wrench on the nut beneath. Hold the bolt still and loosen the nut.
-
-
-
Have a third person place the pipe vise around the riser main, on top of the top flange.
-
Tighten the pipe vise securely around the riser main.
-
-
-
Secure the pipe vise to the top flange with two bolts and nuts to hold the pipe vise in place.
-
-
-
Insert the rod vise between the riser main and the tank, around the pump rod.
-
Tighten the rod vise onto the pump rod.
-
-
-
Screw the coupling onto the end of the riser main.
-
Use a pipe wrench to tighten the coupling onto the riser main.
-
-
-
Add the other two lifting arms.
-
Ensure three things about the arms:
-
They must be equally spaced around the riser main (120° apart).
-
The arms must not touch each other, the coupling at the top, or the pipe vise at the bottom.
-
The openings should alternate, to keep the riser main secure.
-
-
-
As each person lifts up on their lifting spanner, they announce "got it" to let everyone else know they're holding.
-
Once all three lifters have announced that they've "got it," loosen the vise.
-
-
-
With the vise loosened, lift up the riser main 1-2 feet.
-
Lift only as high as everyone is comfortable.
-
-
-
Tighten the pipe vise, with the following procedure:
-
Announce "tightening."
-
Tighten the vise.
-
Announce "Tight."
-
-
-
Tighten the pipe vise, following the same verbal procedure.
-
Repeat the procedure several times:
-
Once everyone is securely holding the pipe, loosen the pipe vise.
-
Lift the pipe.
-
Tighten the pipe vise.
-
Slide the lifting spanners down to a new position.
-
-
-
Lift the riser main up through the pipe vise, until the coupling clears the jaws.
-
Tighten the pipe vise and move the lifting spanners down to a new position.
-
-
-
Lift the riser main high enough that there is room beneath the coupling for the three lifting spanners.
-
Tighten the pipe vise.
-
-
-
Place the rod vise on the pump rod between the section of riser main.
-
Tighten the rod vise on the pump rod.
-
-
-
Use two wrenches to disconnect the upper section of pump rod from the lower section.
-
Once detached, lift and remove the upper sections of riser main and pump rod together, and set them down.
-
To reassemble your device, follow these instructions in reverse order.
