The outside diameter of the travelling valve is such as will provide a clearance with the inside diameter of the working barrel, thus providing a fluid packed piston when the rod is reciprocated. Fluid enters the travelling valve through a plurality of intake ports 31, inclined to the longitudinal axis of the valve, as shown in FIG. The pump displacement is determined on the basis of the pumping speed, unit stroke length, and plunger diameter. The minimum plunger length recommended is normally 3 ft. Slippage or leakage can be calculated using the following equation, adapted from the edition of the Petroleum Engineering Handbook. Plunger lengths longer than 6 ft have not shown to be an advantageous, while specialty pumps may have a plunger shorter than 3 ft. This shifts all the boxes up out of their existing wear tracks to rub on fresh tbg.
Installation and Operation of American Turbine Submersible Pumps
Use a permanent or portable derrick of sufficient strength and rigidity to lift the total weight of the pump safely. Rotate the top end of the shaft by hand, observing the ease of rotation. Top Special Column An adjustable top column flange is used with the adjustable tubing tension nut assembly. The complete API designation includes the following:. Baskets Bells Fenders Kickstands Locks Mirrors Racks. Additionally, there are special pump components, such as valve rods, valves, and tubing drains, that are sometimes beneficial in situations in which the capabilities of normal API pumps and components have been exceeded. Continue installation for all of the standard column pieces.
Tubing threads should run up by hand or with light wrench pressure. A standard ice machine oil may be used as a substitute until supply of the specific oil can be obtained. Leave room for a wrench to be applied to the shaft coupling. An American Turbine Pump is a precision machine, and satisfactory operation is dependent to a great extent upon careful and correct installation. Shafting shipped in boxes may become damaged or spring during shipment without apparent damage to the box.
Description: Replace coupling hole covers or pipe plugs in suction adapter. There should not be more than. The bottom extreme should occur when the two shafts are butted together and the thrust bearing in the bottom of the motor is restricting any further downward movement. Perform the following three checks on this section of column before proceeding with the installation:. Locating Plate - applicable for pump and motor.
