Double Travelling Valve Oil Well Tubing Pumps
Double travelling valve tubing pump description:
Tubing pump models: THM and THC
Subsurface sucker tubing pump is applied to pumping crude oil from oil well with pumping unit and sucker rod.
Through sucker rod,tubing pump is descent to certain depth of oil. When pumping unit drives sucker rod to move up and down, sucker rod drives plunger of subsurface sucker rod pump move up and down in tubing barrel and pump crude to surface.
Main accessories
1. Pump barrel assembly: the body of pump barrel is made of high-quality carbon steel, and inner core is adopted rotary type and high-strength chrome-plated technology, Surface roughness less than 0.4, abrasion and corrosion resistant and long working life.
2. Plunger: the plunger is made of high-quality carbon steel, and the surface is chrome-plated or metal-sprayed which are abrasion resistance and corrosion resistance. According to customer’s requirement, we can manufacture plunger with sand trap and any length of plunger.
3.Accessories: up and down travelling valve assembly and standing valve assembly are made by high-quality carbon steel. Valve ball 9Cr18Mo, valve seat 6Cr18Mo (or high-strength carbolic metal) the material has the quality of high-strength, corrosion resistance and impact resistance.
Features
1. Well tubing pump's capacity is large and durable.
2. Simple structure and easy operation is a main feature.
