centralized operation cargo oil pumping system

It consists of the main pumping system, pumping divertor and glow discharge cleaning (GDC) system.

The Vacuum pumping system of Experimental Advanced Superconducting Tokamak(EAST)

The system efficiency is a primary index for evaluating pumping system. The quality of measured parameters has a great influence on the efficiency of pumping system.

Liquid nitrogen is adopted as protective atmosphere in bell type furnace for which vacuum pumping system are provide also.

The method of calculation for efficiency of pumping system with large variation of water level is studied in this paper.

The aim and the method of mass spectrum analysis for residual gas and the differential pumping system, meanwhile, are introduced.

The safety reliability and system risk estimation formula of electric pumping system are established by means of the safety systematic engineering method.

Different optimal object functions were provided, and the influence of these objective functions on sucker rod pumping system was also discussed based on systematic analysis.

In this paper, the model tests of the wind-powered water -pumping system was conducted and the results of the tests prove that the principle of the system is correct.

Examples have indicated that this model is of practical meaning and of reference value in solving some site problems and in studying reliability of water pumping system in coal mines.

Therefore this new type is not only a better style of pumping system used in onshore oilfield exploiting, but also an ideal equipment for oil production on offshore platform.

It is an important task to increase efficiency of systems and installation freedom between wind turbine and water pump and reduce maintenance for wind pumping systems.

When motors with high or hyper rotating variation are used to drive sucker rod pumping systems, relatively high amplitude fluctuations of motor working rotating speed can take place.

This paper presents the difference equation for calculating displacement of rod string at any position, which is based on the dynamic model of sucker-rod pumping systems.
