Abstract
A well pump breaking tool for mounting on a well pump stand. The tool used in conjunction with a well pump stripping tool. The stripping tool cutting elongated slots along the length of a pump barrel surrounding a pump plunger. The well pump breaking tool is used when the pump plunger becomes seized inside the surrounding barrel due to contamination in the fluid which is pumped. The tool breaking the slotted barrel thereby releases the plunger so it may be reused.
Claims6
A well pump breaking tool for engaging an upper and lower elongated slot cut along the length of a barrel of a well pump, the barrel surrounding a hollow plunger, the well pump breaking tool comprising:
- a base plate;
- first and second vertical arms mounted on opposite sides of the base plate and extending upwardly therefrom;
- a well pump support mounted above the center of the base plate and between the first and second arms, the support having a pointed protuberance extending upwardly therefrom, the lower slot of the barrel received on top of the protuberance, the barrel and plunger resting thereon;
- first and second bolt collars mounted on top of the first and second vertical arms, the collars angled downwardly toward the center of the base plate;
- first and second adjustment bolts received in the first and second collar;
- and
- first and second well pump jaws having pointed end portions, the jaws attached to the adjustment bolts, the pointed end portions of the jaws received in the upper slot of the barrel, by threading the adjustment bolts downwardly the pointed end portions apply pressure on opposite sides of the upper slot until the barrel is broken along the length of the upper slot thereby releasing the hollow plunger from the barrel.
A well pump breaking tool for engaging an upper and lower elongated slot cut along the length of a barrel of a well pump, the barrel surrounding a hollow plunger, the well pump breaking tool comprising:
- a base plate;
- first and second vertical arms mounted on opposite sides of the base plate and extending upwardly therefrom;
- a horizontal strap, the ends of the strap attached to the top of the first and second vertical arm;
- a well pump support mounted above the center of the base plate and between the first and second arms, the support having a pointed protuberance extending upwardly therefrom, the lower slot in the barrel received on top of the protuberance, the barrel and plunger resting thereon;
- first and second bolt collars mounted on top of the first and second vertical arms, the collars angled downwardly toward the center of the base plate;
- first and second adjustment bolts received in the first and second collar;
- first and second well pump jaws having pointed end portions, the jaws attached to the adjustment bolts, the pointed end portions of the jaws received in the upper slot of the barrel, by threading the adjustment bolt downwardly the pointed end portions apply pressure on opposite sides of the upper slot until the barrel is broken along the length of the upper slot thereby releasing hollow plunger from the barrel;
- and
- a third adjustment bolt threadably received through the center of the base plate and attached to the bottom of the well pump support, by threading the third adjustment bolt upwardly and downwardly the well pump support is adjusted vertically on top of the base plate for receiving different sizes of well pumps.
