Anti-sand Sucker Rod Pump with Long Plunger and Sand Setting Device
Introduction
Conventional pump caused various problems, such as sand-sticking, sand-burying and low pump efficiency, which probably leads to production stop because of untimely disabled pump. After long and fully investigation, we have developed a new type multifunctional pump with anti-sand and anti-sticking, which can work with sand.
Structure Features and Working Principle
1) Its barrels surface is treated by special process to achieve better wear resistance and corrosion resistance. During pumping, plunger and barrel are fitted with each other in full length, which can prevent sand into barrel. And it can effectively prevent sand from burying the plunger and sucker rod when pumping stops. With this structure, it can avoid serious abrasion between barrel and plunger because of sand. And the hardened surface of plunger and barrel can also keep nondestructive for longs service life. The sand in oil deposits into tail pipe through annual channel.
2) Valve cage of upper oil outlet, with enlarges flow area, is at outside of barrel. The structure can decrease resistance of oil output.
3) The operation and maintenance of the pump are similar to the conventional pump, with easy disassembling and installation.
