XX- line of portable
X-ray units is designed to the principle of low cost and high reliability,
which is characteristic in convenient to carry, easy to operate, and highly
automated. X-ray tube and HT coil are all produced by DNDT which guarantees
system consistency and keep this unit have a longer service life.
Weight is further
reduced with the using SF6 insulation and Forced cooling fan, prolongs X-ray tube
life, makes this unit suitable for construction site, field work and high above
the ground work..
Control unit is designed
with microprocessor control and frequency conversion technique. With functions
of fully automatic warm-up program, fault display, over voltage and mis-start
protection, the stability and service life are much improved

1) Standard:Â API 11AX
2) API and ISO certified
3) Type:Â Tubing Pump
4) Photo
5) Description
The workover process of tubing pump is: firstly the barrel being connected to the tubing is directly run into the well at desired depth and then the plunger is run into the barrel with the sucker rod.
Â
6) Working Principle
Â
In the upper stroke, the plunger is on the bottom of the tubing pump. Because the hydraulic pressure from the uper tubing, both up and traveling valves will close, When the plunger go up, the stationary valve open and oil will go through the pump, since the bottom pressure is higher than the uper pressure, then the fluid will be forced to go through the stationary valve and flow into the tubing.
In the down stroke,the traveling valve open and the presure drive the oil go into the plunger from the side holeof the extractor, then go into the tubing.
Â
7) Structure
The subsurface sucker rod pump is consist of tubing coupling, extension nipple, barrel coupling, barrel, traveling valve, plunger, extractor, stationary valve.Â
