Abstract
The utility model relates to a multi-spiral screw pump, which relates to the screw pump for transportation of high-concentration and highly-viscosity media of industries of oilfield oil production industries, crude oil transportation industries, chemical industries, paper-making industries, etc. The utility model is mainly provided with a pump casing and a screw which is a multi-spiral screw. The utility model has the advantages of high production efficiency which can be increased by more than 30 %.
Description
The utility model relates to a kind of screw pump that industries such as oil field oil recovery, Crude Oil Transportation, chemical industry, papermaking are carried high dense high viscosity medium that is used for.
Existing screw pump screw rod has two kinds on single, double spiral, and its shortcoming is that efficient is low.
The purpose of this utility model is the high many spiral screw rods pump of a kind of manufacturing efficiency of design.
The purpose of this utility model is achieved in that it comprises pump case (stator) 2 and the screw rod (rotor) 1 that is connected with its conjugation, and we make many spiral screw rods with screw rod, i.e. the screw pump of three or three above spirals.
The utility model has the advantages that the manufacturing efficiency height, generally can raise the efficiency more than 30%.
Accompanying drawing is a generalized section of the present utility model.
Embodiment: pump case 2 liner oil resistants, acidproof, wear-resisting, temperature resistant rubber, the screw rod that is connected with the pump case conjugation is made triple helical, four spiral screw rods.
Claims (1)
1, many spiral screw rods pump comprises pump case [2], it is characterized in that screw rod [1] is many spiral screw rods.
