Once the pump has been placed in its seating location, the weight of the sucker rods on the pump pushes the rubber element outward until contact with the tubing wall is made. two hold down rods, two washers & … All three companies offer a plethora of matching tools and accessories. 54th Southwestern Petroleum Short Course, 2007, 45-59. 11AX. This pump has the hold-down at the top of the barrel, so the entire barrel and standing valve of the pump extend below the pump seating nipple. Additionally, a pump with tighter fit tolerance/waste space, smaller pump diameter, increased stroke length, adequate downhole separation, and properly designed pump gas anchor should be considered along with properly placing the pump intake above or below the perforations as discussed in Sucker-rod lift. Organization for Standardization (ISO), Geneva, Switzerland. Paper 16 presented at the 2000 Southwestern Petroleum Short Course, Lubbock, Texas 12–13 April. This condition normally occurs because of inadequate pump spacing as the fluid level pumps down or because the pump has inadequate compression ratio/excessive waste space for the seating depth for the designed pumping parameters. API Spec. polished stainless steel. The last normal operating problem is caused by solids entering the pump. Tubing pumps are so named because the working barrel of this pump is coupled with the production-tubing string. First step is to determine the exact model for your hot rod, download the Rod Tops Measuring Guide (PDF). Muth, G.M. Black Gold Pump & Supply, Inc. © All rights reserved. Williams, B.J. These slick hold down clamps securely hold your lines (brake, wiring, gas or cable) in place. The pump designation is part of API Spec 11AX and describes the main specifications of an API subsurface pump. As this occurs, system control should be adjusted to continue producing as required, without overpumping by running the pump more often. Slippage in sucker-rod pumps takes two forms: static and dynamic slippage. Comes with gasket as pictured. 11AX, Subsurface Sucker Rod Pumps and Fittings, eleventh edition. Washington, DC: API. The pump manufacturer typically machines or obtains subcontract pump components for future assembly of the pump by a pump shop. • Static slippage is the dominant factor and occurs only during the upstroke of the pump; it is caused by the pressure differential across the plunger-barrel fit. This length then should be used in the barrel-length determination. Downhole sucker-rod pumps are a key component of a sucker-rod lift type of artificial lift system. Example: 20-125-RHBC-10-4-2-2. New cables are recommended with each new top. The Don-Nan Top Seal prevents a stuck pump scenario caused by solids accumulation around the hold-down. covers the length range for various pump types. Tight clearances (less than 0.003 in.) In the past, tighter fit tolerances (< 0.003 in.) If sand is an issue, nonstandard accessories such as a top seal can be used to prevent a stuck pump. This page discusses each of these components. This type of pump is ideal for medium depth, sandy wells. 11AX. This type of arrangement is great with sandy wells (especially shallow ones with a depth of less than 5,000 feet), due to the fluid’s whirling motion created during operations in the area at the pump’s top. An overpumping condition is indicated when there is a fluid pound more than one-quarter of the way down on the downstroke because of insufficient fluid in the well to charge or fill the downhole pump. [1]. – Watson, B. The ends of the cables hold the top to the frame. Hold Down Cables: A pair of cables, one on each side, thread through pocketed hems on the main top sides. 2001. These clamps are for a 1/2 inch single line. Because the pump displacement is greater than the well capacity, the system will require some type of well control to prevent constant operation and overpumping of the well. ed. 1-3940 $18.00 _____ 1955-1957 chevy battery hold down.

Separator 3: 2 – 3/8 Poor Boy Separator & Top Hold-down; The reached results with the selection of three separators are due to the dependence of Pdmax with a 21. 11AX was modified to add not only new sizes and types of pumps with new quality, inspection, and tolerance requirements, but also standardized, widely used pump-component materials. This was required to determine if there were recommended allowable loads that could be subjected to rod pumps of different types, sizes, and metallurgy. ; N = pumping speed, spm; and D = diameter of the pump plunger, in. It is recommended that the length of the plunger is increased 1 ft/1,000 ft of well depth, up to a 6-ft maximum length. There are seven major components for downhole rod pumps: standing and traveling valves, plunger, barrel, seating assembly, pull tube or valve rod (for insert pump), and the fittings that hold the assembled pump together. This is the "X-type" barrel. 95 $30.50 $30.50. The types of pumps, sizes, and component materials that are included in the API standards are based on the best industry practices that meet widespread industry needs.

However, these items should be selected with care and used only after the best production effort has been thoroughly tested with standard components. 29 List List Price $30.36 $ 30 . Top valve acts as check valve to keep sand out of pump. 1999. The top hold down rod pump (where the pump is below the seating nipple) is more commonly used as it is resistant to sand sticking and is typically easier to remove from the well when removal is required. differential pressure across plunger, psi, Nominal tubing size (from 1.9- to 4.5-in. They are not visible after installation. − Rod (Insert) Pumps, 3-types: based on where the hold-down is located (top or bottom) & whether the barrel is Stationary or Traveling. 11AX. Richardson, Texas: SPE. Other indications of overpumping are if the pump volumetric efficiency is less than 70% or if a downhole fluid-level survey shows that the normal operating fluid level is at or very near the pump intake. Stuck pumps In AGIBA application stuck pumps which existed only in the Bottom Hold-Down type. In the early 1990s, an industry task group analyzed the stresses that react on a downhole rod pump. Hold Down Cables: A pair of cables, one on each side, thread through pocketed hems on the main top sides. Notice the standing valves turbulence when you have your pound much lower in the stroke. [1] Using the surface stroke length vs. the downhole Sp length, and designating this length as the rounding factor, may provide sufficient barrel length to accommodate the spacing length some operators or pump shops suggest. may result in excessive leakage by the pump. These Water Pumps are an exact reproduction with the smooth casting correct for the MB. Abstract or Worlcat, Use this section to provide links to relevant material on websites other than PetroWiki and OnePetro. There is a wide range of plunger (or pump-bore) sizes standardized by the industry. 11AX. This group developed the burst, collapse, and axial-loading equations to determine these limits and the associated maximum recommended setting depth for sucker-rod lift pumps, [4] published in API RP 11AR. Insert pumps are installed by running in hole with the rod string. Solutions include using different types of pumps designed to handle fines and solids, such as three-tube pumps or soft-packed plungers, and using harder materials or coatings for the pump components. 47th Southwestern Petroleum Short Course, 2000, 117-36. surface stroke, a 48-in.-long plunger with a steel rod string and a designated 2 7/8 × 1½-in. ... manitou 4wd track rod end complete assembly 415/485mm long 27/30mm cone f22 inner thread (oem 601217) price: ... manitou merlo perkins top radiator hose price: €88.00 exc vat .
