定义
A specialized screw component designed for metering screws or feeders that precisely controls the flow rate and volume of bulk materials in industrial processes. It features specific geometric parameters (pitch, diameter, flight design) optimized for material characteristics and feeding accuracy requirements.
工作原理
The screw rotates within a barrel or housing, creating a positive displacement action that moves material from the inlet to the discharge point. The screw geometry determines the volumetric capacity, while rotation speed controls the feed rate. Material is conveyed through the progressive cavities formed between screw flights.
材料
Typically manufactured from wear-resistant materials: hardened tool steel (AISI D2H13)stainless steel (304316)or specialized alloys with surface treatments (nitridinghard chrome platingtungsten carbide coating) for abrasive applications.
Pitch
0.5-2.0 times diameter
Length
500-3000 mm
Diameter
20-200 mm
Tolerance
±0.05 mm
Flight Type
Single, double, or variable pitch
Concentricity
<0.02 mm
Surface Hardness
HRC 55-65
标准
ISO 3408DIN 103ISO 9001

常见问题

What factors determine the selection of a metering screw?

Material characteristics (density, flowability, abrasiveness), required feed rate accuracy, process conditions (temperature, pressure), and compatibility with the feeder housing.

How does screw pitch affect feeding performance?

Pitch determines the volumetric capacity per revolution. Smaller pitches provide finer control for precise metering, while larger pitches increase capacity for bulk materials.

What maintenance is required for metering screws?

Regular inspection for wear, cleaning to prevent material buildup, lubrication of bearings (if applicable), and periodic calibration to maintain feeding accuracy.
