Abstract
A crude oil sampler comprises a piston-type sampling head and an electrically-driven push rod, wherein the electrically-driven push rod is connected with a piston rod of the piston-type sampling head via a forwardly/reversely-connected bolt, and is electrically connected with a micro computer controller. By adopting the crude oil sampler provided by the utility model, the shortcoming in the conventional sampler adopting hydraulic pressure as power that the hydraulic oil is mixed with the sampling oil is overcome; the sample is authentic, objective and fair; and the sampling level of crude oil is improved.
Description
Technical field
The utility model relates to a kind of crude oil pipeline ST, is used for the online sampling that crude oil pipeline is carried.
Background technology
No matter be domestic production or the external ST of introducing at present; Its sampling method all is power with hydraulic pressure; The promotion sampling cock moves reciprocatingly and reaches the sampling purpose; Because piston can be moved to the sample cavity direction, then the pressure of back hydraulic cavities must be greater than sample cavity pressure, and the method makes the hydraulic oil as power mix in sample cavity with the ducted sample oil of get; Thereby make institute's sample thief lose representativeness, this phenomenon mainly is due to wearing and tearing and O type circle aging of piston and plunger shaft.
Summary of the invention
The purpose of the utility model provides a kind of crude oil pipeline ST, and overcoming original is the technological deficiency that the hydraulic oil that exists of the ST of power and institute's sample thief oil mix with hydraulic pressure.
The purpose of the utility model realizes as follows: this crude oil pipeline ST, comprise the piston type sampling head, and other has an electric pushrod, and electric pushrod is connected with the piston rod of piston type sampling head.Piston type sampling head and reciprocating thrust unit electric pushrod be for dividing a body structure, thereby can to avoid with hydraulic pressure be the contaminated product phenomenon that the one-piece construction of power causes.
Be connected through forward and reverse coupling bolt between the piston rod of electric pushrod and piston type sampling head.
Electric pushrod is electrically connected with microcomputer controller.
During work by microcomputer controller by the program of inserting in advance; Send the direction of motion instruction and to electric pushrod required power supply is provided simultaneously to electric pushrod on request; Electric pushrod is pressed the instruction of microcomputer controller; Push away before doing or the motion of post-tensioning, the piston that the connection through forward and reverse coupling bolt promotes the piston type sampling head moves reciprocatingly, thereby reaches the sampling purpose.Forward and reverse coupling bolt is except that playing the effect that connects electric pushrod and piston type sampling head; Also play the effect of adjustment piston type sampling head movement travel simultaneously; Owing to adopt electric energy to be used as power, there is not other medium in the novel sampling head, definitely guaranteed the authenticity of institute's sample thief.
It is the hydraulic oil and the oily defective of mixing of institute's sample thief that the ST of power exists with hydraulic pressure that the utility model has overcome original, has guaranteed the authenticity of institute sample thief, and objective and fair has improved the level of crude oil sampling.
