1. Structure of Sucker Rod Abrasion-proof Coupling Description

Sucker rod abrasion-proof couplings are class supporting tools of pumping well, it applied to eccentric wear oil pump, especially the oil pump and directional deflecting well in which the eccentric wear is above the neutral point. If the eccentric wear is below the neutral point, it can be used together with the nylon centralizer to get a better eccentric wear prevention result.

The core technology is to coat AOC-160 alloy powder on the surface of sucker rod coupling. The coating which is thicker than 0.25mm is wear resistant, corrosion resistant and low friction. Wear resistance is 10 times of normal coupling and it reduces 3 times of abrasion.

2. Main Features of Sucker Rod Abrasion-proof Coupling

  • Simple structure

  • Convenient operation

  • Long service life

  • Low cost

Q:What are the installation requirements of the card sleeve joint?
The ends of the pipe shall be flush. The pipe should be flush in sawing grinding wheel and other tools, and burr cleaning and high pressure air blowing after use.When installing, the coaxiality of pipe and joint body should be kept as far as possible. If the pipe deflection is too large, it will cause sealing failure.The pre assembly force should not be too large. The inner blade of the clamping sleeve is just inserted into the outer wall of the pipe, and the clamping sleeve should not be deformed obviously. When the pipeline connection, and then according to the specified tightening force assembly. The tightening force of the phi 6-10mm card sleeve is 64-115N, Phi 16mmr 259N, Phi 18mm is 450N. If the sleeve is badly deformed at pre assembly, it will lose its sealing effect.(2) prohibit adding sealant and other fillers. In order to obtain better sealing effect, the sealant is coated with sealant, and the sealant is poured into the hydraulic system, causing the hydraulic components, such as damping holes, blocked and so on.(3) when connecting the pipe, the pipe should have enough deformation allowance to avoid the tensile stress of the pipe.(4) when connecting the pipeline, it should be avoided to be subjected to lateral force; the lateral force will cause the seal to be too lax.
Q:Joint type of pipe joint
NPT is the abbreviation of National (American) Pipe Thread, an American Standard 60 degree taper pipe thread, used in North America. National standards refer to GB/T12716-1991PT is the abbreviation of Thread Pipe, is a 55 degree taper pipe thread sealing, belonging to the Whitworth family, for the European and Commonwealth countries. Commonly used in water and gas pipe industry, taper regulations of 1:16. national standard is available on the GB/T7306-2000G is a 55 degree non thread sealing pipe thread, belonging to the family of Wyeth thread, marked G for cylinder threads. National standards refer to GB/T7307-2001In addition, the 1/4, 1/2 and 1/8 marks in the thread refer to the diameter of the thread size, in inchesYes, my wife usually refers to the size of the thread by one point, one inch equals 8, and 1/4 inches is 2, so by analogy
Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Four, flexible pipe joint internal structure and KRJ internal structure is slightly different, flexible pipe joint no retreat or small platform, and the latter is large return platformFive, flexible pipe joints, standard clamp type flexible pipe joints, disassembly can be worn down, shoulder type flexible pipe joints can not be.Note: some units in the market now confuse the two products with the aim of selling high priced products at lower prices so that they can make more profit margins. To ask for the data parameters of the drawing, to judge whether it is a flexible pipe joint or a flexible pipe joint.
Q:Do you need adhesive for the sleeve joint of PVC wire pipe?
The Construction Code stipulates that this is true, but it is rarely used in general decoration.
Q:Silicone gasket, rubber gasket, water pipe joint which is good?
More suitable for food grade high water pipe, especially high temperature resistance, high temperature water pipe is best to use silica gel gasket
Q:Can the pressure vessel pipe joint adopt G thread? Why?
1 、 pressure vessel pipe joints do not use G thread, because G thread is not sealed enough.
Q:Air conditioning outdoor units, pipe joints, frosting, or even icing
Find the right size of the six angle wrench, facing the cut-off valve, counterclockwise turn on the valve, clockwise turn off the valve.
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
One foot (25.4mm) is divided into eight parts, 1/4, that is, 2/8 is two in charge, 1/8 is 1 in charge, 3/8 is 3 in charge, 1/2 is 4 in charge, in order to calculate nominal diameter
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
As the master of the world pipe joint wellock, stainless steel NPT thread pressure they can do 200-760BAR, and different pressure according to different sizes
Q:How to distinguish between flared pipe joint and welded pipe joint
Therefore, it is widely used in refining, chemical, light industry, textile, national defence, metallurgy, aviation, ship and other systems. It is also suitable for various hydraulic transmission lines such as mechanical engineering, machine tools, equipment, etc..
