screw pump

A screw pump is a special type of positive displacement pumps that has two or more intermeshing screws rotating axially to deliver fluids.

Machinery and other production methods, screw pump system is characterized by a higher system efficiency, a study of its great significance.

In the light of the frequent breakdown and badly lifting efficient of using conventional screw pump recovering viscous crude.

The viscosity of the higher pulp categories, sticky paste and of the transmission fluid, the proposed optional screw pump.

This article mainly analysis the surface driven screw pump system.

Twin-screw pump is outside the mesh of the screw pump, which uses mutual engagement, and do not touch the two screws for pumping liquids.

The utility model belongs to the torque testing device of the screw pump well on an oilfield pump recovery wellhead.

And centrifugal pumps compared with single-screw pump do not need to install the valve, while the linear flow of traffic is stable.

Twin-screw pump as a positive displacement pump, pump room exhaust inhalation chamber should be strictly separated.

Screw pump has its unique advantages and is widely used in transporting the sticky liquid sludge in ship.

At present, the screw pump is widely used in exploiting crude oil with high viscosity, high sediment concentration or high gas content.

The utility model discloses a downhole well washer of the oil well which solves the problem of the washing of a screw pump well.

This paper is focused on the design of a high-powered surface direct-driven screw pump systems to enhance the oil extraction efficiency.

The submersible twin screw pump, an emerging and high efficient method of artificial lift, is underdeveloped and there is no mature theory.

Screw pump can transport lubricants, fuel transportation, oil and transport all kinds of polymers, used for conveying sticky liquid.

This paper presents the main factors on choosing a screw pump and details methods for selecting this kind of pumps.

The equal wall thickness hollow screw pump rotor is mainly applied to the transport of viscous liquid.

Twin-screw pump can be divided into internal and external bearing bearing two forms.

In this paper, it introduced the screw pump in aspect of present situation and development trends and working principle.

Firstly, starting with working principle of single screw pump, the force on stator of single screw pump is analyzed.

Studying for screw pump's displacement and volume efficiency and Pump efficiency, giving the formula.

Taking stator of single screw pump as the object studied, the using live is studied in this paper.

Analysis screw pump system, get the mechanical model of rod string, deduct and calculate undertaking load of rod string.

This pump is mainly comprised of 4-pole submersible electric motor, protector, connecting mechanism and special screw pump assembly.

Because the exist of sand, the components of screw pump will be sheared slowly, the lifespan of screw pump is usually 10~12 months.

Applications of screw pump have made great progress since recent years.

G is strictly prohibited without the media-type screw pump under air operation, so as to avoid damage to the stator.

and high-speed screw pump suitable for high sand content and high oil viscosity must be used.

According to the serious rubber latex break and block in the imported centrifugal pumps, the new-type double screw pump is developed.

Single screw pump has become a main approach of pumping emulsion matrix by its advantages.

Company production of some products gear pumps, screw pump has achieved export.

In comparison to the beam pumping unit, the screw pump single well investment cut down 100000 yuan.

Screw pump features: the loss of small screw pump, good economic performance.
