Product catalog summary

Overview
The document provides an in-depth analysis of the metering and mixing systems by Hilger u. Kern / Dopag Group, specifically for the production of rotor blades used in wind energy turbines. It emphasizes the growing significance of wind power in global electricity generation and the necessity for precise production parameters to enhance system longevity.

Key Requirements for Metering and Mixing Systems

Adherence to exact mixing ratios.
Flexibility in output rates.
Quick achievement of operational conditions.

Production Processes
The document details three primary production processes in rotor blade manufacturing:

Vacuum-supported infusion for fiber matting impregnation.
Bonding of rotor blades or segments.
Surface coating of rotor blades.

Technical Specifications

Flow rates depend on mixing ratio and viscosity, ranging from 2 to 60 l/min.
Volumetric mixing ratios range from 100:5 to 100:100.
Material supply options include circular pipelines, original containers, and pressure vessels.
Viscosity ranges from 1 mPas to 500,000 mPas.
Material characteristics include unfilled, filled, and abrasive options with a MOHS hardness of 7.
Standardized power supply at 3 × 400 V / 50 Hz with a maximum air inlet pressure of 6 bar.
Dimensions and weight vary across systems.

Silcomix Metering and Mixing Systems
These systems are tailored for processing liquid silicone rubber (LSR) and are applicable in industries such as automotive, electronics, and medical.

Piston pump systems (silcomix P20, L200, H200) handle fixed mixing ratios of 100:100.
Electronic systems (silcomix V200) manage mixing ratios from 100:100 to 100:10.

Material Balancing System
The document introduces a material balancing system that minimizes material waste during drum changes, leading to significant cost savings.

General Information
The document provides technical data on metering and mixing systems for rotor blade production, focusing on liquid silicone rubber (LSR) products used across various industries.

Types of Metering and Mixing Systems

Piston Pump Metering and Mixing Systems: Models silcomix P20, L200, and H200 process LSR with a fixed mixing ratio of 100:100, using piston pumps for direct material supply and homogeneous mixing.
Electronic Metering and Mixing Systems: Model silcomix V200 processes LSR with mixing ratios from 100:100 to 100:10, utilizing electronic volume counters for precise metering and mixing.

Material Balancing System
A newly developed system reduces material waste in 200-liter drums from 4% to 1%, offering potential savings between €3,350 and €31,150 annually, depending on part shot weight and drum change frequency.

A deviation of less than 1% of the mixing ratio can not only be achieved with the compomix I, but the output rate can also be modified during production. Depending on the system configuration, magnetically-coupled, leakage-free axial piston pumps are used, which due to the principle of construction present no internal leakage during changes in rotational speed. Additionally, they are hermetically sealed at the drive end which is important when feeding hy groscopic hardeners. The metering system range for the processing of unfilled infusion resins combines highly accurate metering pumps with...

gluem x The reliable bonding of both halves of the rotor blades is a fundamental aspect of the performance of a rotor blade. With the gluemix the adhesive used for bonding is provided via gear pumps. During the processing of high-viscosity, stable products, the metering of the A-component is carried out via a specially designed gear pump that is integrated directly into the follower plate for use with 200 litre size containers (FIP technology). Thus the gear pump is positioned closer to the medium to be delivered, allowing higher volumes and delivery pressures in comparison with other follower...

gelcom x The gelcomix has been especially developed for processing highly thixotropic materials onto the un treated surfaces of rotor blades. Output rates of up to 5 l/min can be achieved with gear metering pumps, which are also suitable for abrasive fillers. Magnetically coupled axial piston pumps are used for the B-component. The material is supplied from material pressure vessels that are installed on the chassis of this mobile system. With gelcomix technology, materials with viscosities of up to the flow limit cannot only be applied but the mixing ratios are also adjust able within a wide...

General Information In the next few years, the proportion of electricity generated worldwide by wind power will steadily increase. However, effective conversion to this technology will only be possible if the systems involved can be assured of a long life span. That presupposes that production-related parameters are adhered to precisely during production. Automated Metering and Mixing Systems for the production of rotor blades must fulfill the following requirements: • Exact compliance to the specified mixing ratio • Highly flexible output rates • Rapid attainment of working conditions For the...
