Overview

    G-type screw pump is an internal meshing closed-type screw pump, which belongs to rotor type positive displacement pump. Because of its strong adaptability to medium, smooth flow, good suction performance and small pressure pulsation, it can transport various flowable. In addition to the medium, it can also transport highly viscous medium, medium containing hard suspended particles or solid particles, medium containing fiber, good regulation performance, wide range and high efficiency. Therefore, in environmental protection, shipbuilding, petroleum, medicine, Various industries such as daily chemicals, food, brewing, construction, mining, chemicals, printing, paper, power plants, and boilers are widely used.

working principle

    The single screw pump is an internal meshing rotary positive displacement pump. The main working components are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometry of the rotor and stator, several separate sealed cavities are formed respectively. The operation of the medium in each sealed chamber is continuously, uniformly and volume-changed from the suction end to the extrusion end. Due to these characteristics, the single-screw pump is particularly suitable for the following conditions:

    1. Deliver high viscosity media

    2. Transporting media containing solid particles or fibers

    3, requires contact, pressure stability, no cyclical pressure fluctuations

    4, requires a small amount of agitation, does not destroy the inherent structure of the transport

    5, low noise

Model Description

Structure description

Application range:

    Single-screw pump is a general-purpose pump. The flow rate can be changed according to the requirements. The running speed can be high or low. The outlet pressure can be increased with the number of pumps. For each additional stage, the pressure increases by 0.6MPa. Wide range of applications and industries:

    1. Environmental protection: the transportation of industrial sewage, domestic sewage, muddy water containing solid particles and short fibers, especially suitable for oil-water separators, plate and frame presses, etc.:

    2. Shipbuilding industry: transportation of mediums such as wheel bottom cleaning, oil water, oil slag, oil sewage, etc.;

    3. Petroleum industry: transporting crude oil, a mixture of crude oil and water, a mixture of coal gas and water, pouring polymer into the formation, etc., thereby reducing the cost of mechanical oil recovery, mining gas fields, and increasing oil recovery;

    4, medicine, daily: a variety of sticky pulp, emulsion, a variety of ointment cosmetics delivery;

    5. Food canning industry: transportation of various viscous starches, edible oils, honey, syrup, jam, butter, surimi and its scraps;

    6. Brewing industry: various fermented viscous slurries, concentrated distiller's grains, grain slag, various sauces, pulps and mucilage containing solid solids;

    7. Construction industry: spraying and conveying of cement mortar, lime slurry, paint and other pastes;

    8. Mining industry: Groundwater and slurry water containing solid particles in the mine are sent to the ground;

    9. Chemical industry: various suspensions, greases, various colloidal pulps, various adhesives;

    10, printing, paper industry: high-viscosity ink, PVC PVC polymer paste and various concentrations of pulp paper, short fiber slurry transport.

    11. Industrial boilers and power plants: transportation of coal water slurry.
