Introdução

This guide will show you how to replace the riser main with the help of a tripod.

The riser main can, alternatively, be replaced using lifting spanners, but a tripod allows the process to be done by two people. Still use caution when using a tripod.

    • Before performing any repairs, perform a water test on the pump by raising and lowering the handle a full 40 strokes. A properly performing pump will yield greater than 10 liters.

    • Remove the hex head bolt from the top of the access door on the pump head.

    • On reassembly, this bolt should be hand-tight.

  45. India Mark II Riser Main (Tripod) Replacement: passo 45, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 45, imagem 2 %32
    • This procedure requires an important communication dialog between the rope operator and the pipe vise operator.

    • The rope operator's job is to pull hard on the rope to take up the slack, and announce that they've "got it," to let the vise operator know that they're holding the weight of the riser main.

    • The vise operator will then announce "loosening," and loosen the pipe vise.

  46. India Mark II Riser Main (Tripod) Replacement: passo 46, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 46, imagem 2 %32 India Mark II Riser Main (Tripod) Replacement: passo 46, imagem 3 %32
    • With the pipe vise loosened, pull the riser main up out of the well.

    • Pull only as high as the tripod vise operator can comfortably reach.

  47. India Mark II Riser Main (Tripod) Replacement: passo 47, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 47, imagem 2 %32 India Mark II Riser Main (Tripod) Replacement: passo 47, imagem 3 %32
    • The pipe vise operator then announces "tightening," and tightens the pipe vise.

    • It is now safe to loosen and remove the tripod pipe vise.

    • Be sure to loosen and then fully remove the tripod pipe vise from the riser main. Sliding it down the riser main will scratch the pipe, creating dangerous sharp grooves and causing rust.

  48. India Mark II Riser Main (Tripod) Replacement: passo 48, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 48, imagem 2 %32
    • Lower the tripod pipe vise down to the bottom of the exposed section of riser main pipe.

  49. India Mark II Riser Main (Tripod) Replacement: passo 49, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 49, imagem 2 %32 India Mark II Riser Main (Tripod) Replacement: passo 49, imagem 3 %32
    • Secure the tripod pipe vise to the riser main pipe and tighten it securely.

  50. India Mark II Riser Main (Tripod) Replacement: passo 50, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 50, imagem 2 %32 India Mark II Riser Main (Tripod) Replacement: passo 50, imagem 3 %32
    • Repeat the lifting procedure: loosen the pipe vise and pull on the rope to raise the riser main another few feet.

  51. India Mark II Riser Main (Tripod) Replacement: passo 51, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 51, imagem 2 %32 India Mark II Riser Main (Tripod) Replacement: passo 51, imagem 3 %32
    • The tripod has an indentation built into its top to guide the riser pipe.

    • As you're raising the riser pipe, guide it into the indentation.

  52. India Mark II Riser Main (Tripod) Replacement: passo 52, imagem 1 %32 India Mark II Riser Main (Tripod) Replacement: passo 52, imagem 2 %32 India Mark II Riser Main (Tripod) Replacement: passo 52, imagem 3 %32
    • Lift the riser pipe until the first coupling clears the pipe vise.

    • You will need to open the pipe vise wider to accommodate the coupling.

    • Once the coupling is through the pipe vise, tighten the pipe vise.

    • Be sure to raise the riser main pipe high enough that you can attach the tripod pipe vise to the section of pipe beneath the coupling.

    • From here we have pictures for loosening a coupling with the tripod?
