YTRON-Y ByPass system - Incorporation of free flowing powders without a tendency to stick of form lumps such as Silica, Active Carbon, HPMC, Cocoa, Flour, Carbon Black, can be drawn in below liquid level by the negative pressure created by the rotor/stator system. The venturi shaped stator and the negative pressure created by the flow it affects, draws the powder in, dispersing it instantly and homogeneously into the liquid. The formation of lumps is eliminated.
Certain powders with a low bulk density can be sucked directly and dust-free from a bag or other container.
Liquids such as S.L.E.S., concentrates, additives, and pastes can as well be pumped in via the YTRON-Y ByPass tube, directly into the turbulent zone in the YTRON-Y mixing head. They are then quickly and instantly diluted or dispersed into the batch. The mixing efficiency of YTRON-Y remains unchanged.
|
|
YTRON-Y rapidly and homogeneously mixes, without aeration, liquids and moderately viscous products. The standard production range includes five different group sizes, with power ranging from 0,25 kW to 55 kW. This corresponds to vessel sizes of up to several million liters volume.
By selection of the suitable mixing rotor, either gentle mixing or intensive shear is applied to the product, but in all cases the mixing action will be very efficient.
The robust construction means that it does not require bearings or seals in the immersed part and therefore involves no hygienic risc. Hygienic execution with surfaces up to mirror polish are available. The use under ATEX conditions is no problem, providing is has been respected in the engineering phase of the project.
Typical use is in the Food, the Chemical , Pharmaceutical and Construction Industries.
Additional services are the supply of hoists (wall mounted, floor mounted or mobile) with manual, electrical or pneumatic drive.
Optional: Support for fork lift or tackle block.

Turbine Sentry - System Overview
An overview of the complete system and how this system is of benefit to gas turbine operators.
A typical system comprises three parts:
Blade Sentry - Measurement Pyrometer
The non-contact thermometer is mounted through the gas turbine casing and measures the temperatures of individual rotor blades.
Rotor Sentry - Data Acquisition System
The DAS logs individual blade temperature readings taken by the measurement pyrometers, samples and processes the data for use by the data analysis software, Data Sentry.
Data Sentry - Data Analysis Software
This powerful pc-based software utility has all the tools and functions necessary to obtain a complete picture of how efficiently the gas turbine is running, as well as identifying potential problems at an early stage.

One of Allen Gears key assets is the ability to use our extensive knowledge of gear technology and application requirements to provide solutions that achieve the optimum transmission solution for the desired drivers. We achieve this through combining the transmission technologies of parallel shaft, epicyclic and bevel gearing to produce combination gearboxes that best meet the installation and operation requirements.

Grade: N42
size: 2" x 1" x 0.5"
coating: Ni-Cu-Ni
Magnetized through the Thickness 0.5"
Applications: wind turbine or other projects
For years, we have been offering the magnets for wind turbines worldwide. we have a team of technicians with rich experience in the R&D of magnets for wind turbines.
Because of the maximum working temperature, magnets using in Wind turbines are series SH, such as grade 42SH, 45SH and so on
The magnets for wind turbines, usually we offer L-T series for wind generators, Compared to the Conventional Formula and the T-series, the correlative temperature coefficient and weight loss are better. it will well prolong the life twice than usual.
For the details about the L-T series or the magnets, please do not hesitate to contact us or view our PDF Catalogues " special magnets for wind turbine" , we are at your services any time.

CENTRALIGN® is a laser alignment system that uses the inherent high precision of the laser beam as its reference, as opposed to the conventional methods that utilize dummy shafts and piano wires, for the precise adjustment of turbine internal parts. It offers accurate and independent alignment records. CENTRALIGN® improves productivity by shortening the outage time of turbines.
