Flow control or monitoring can be provided optionally but is not considered to be essential to the performance of the machines and set a new standard of automation in this class of machines. A two blade electrostatic oiler for continuous strips is basically made as follows see 1 e 2. The nozzle is designed to pass any particulates in the fluid to prevent clogging.
The orifice dia is about 10 times wider than the conventional slot blade which is virtually self cleaning and mantenance free. Moreover the oil deposited by conventional means is free flowing from the sites of coils severely contaminating storage floors. High Voltage Power Supply – Low-amperage source, typically operated at KV, is used to power electrostatic nozzle. In practice the fluid mist is negatively charged and the metal surface is kept at ground potential connecting it to the mass, which is very easily done due to the presence of large metals structures in every process line.
When it is not possible to fit on the line a standard enclosure many special designs studied for the special job are available. As a first in this field the bells revolutions are electronically controlled.
Electrostatic oilers – Technical specification
The enormous advantage of the electrostatic principle is its more homogenous, constant and reproducible spreading of well measured oil quantities at variable strip widths and speeds, not at least thanks to a specially developed spraying bar. Threading tables are normally driven by air cilynders.
With the most modern electronic generators the same results are obtained employing ma 0.
Electrstatic machines can be moved out of the line, so that production is also possible without oiling. Improves Coil Handling – Reduces telescoping of coils.
Positioning System – Spray header can move on and off line via a variety of retraction mechanisms. The rules of selection are generally flexible and the best type of atomiser fot the application to hand would usually be assed on a one-to-one basis.
Quality Certifications ISO Stay up to date on industry news and trends, product announcements and the latest innovations. In every case the atomisers are connected by means of a special High Voltage cable to a Elecfrostatic generator. Improves Safety and Housekeeping – Precise targeting and control eliminate oildr and reduce hazard and mess of oil runoff from coils, both for rolling mills and their customers.
Electrical charges of the same name repel each other, electrical charges of opposite name attract each other. In both cases oil consumption is well over the theoretical – often even three or four times as much and the uniformity of the coating obtained is very poor. System subassemblies include multiple 3 in. PNEUMODYN airspray units Manufactured again by our Elettrospray Division, these atomisers are a development of conventional electrostatic painting guns and may be used for high output applications typical of Temper or Oildr lines or to coat individual sheets immediately ahead of a press.
Call View Supplier Save Shortlist. Control and instrumentation can be located on coater assembly or remotely. In any case oil flows from the atomiser in form of cuspid wich under the effect of the electrostatic pressure break in tiny droplets forming a curtain of very fine oil mist.
The type of oil can be exchanged quickly. Start Up – Assisted by TDC engineers and designers who remain on-site through successful start-up and operation.
Moreover because of a much lower capacity of the system the energy stored and released in case of a spark is much lower. Therefore at the maximum rated voltage of kV a W power is involved.
The shielded high voltage cables are therefore wery short and do not cross the working site with a great safety advantage. The blade edge is formed as a single plane, externally wetted from a row of holes uniformly spaced along the blades body. Typical Line Speeds – Up to fpm in existing installations, higher speeds are possible.
The system is ideal for application of very low coating weights of DOS or electrstatic products normally required on Tin-plate, Black-plate and Aluminium lines. Compact design fits into most lines without modification to existing equipment.
The provided block and alarm circuits render the use of these generators extremely safe.
Also offers roll coating equipment and coil process line maintenance services. Terronics electrostatic oilers provide a rlectrostatic way to oil steel strip for rust protection, lubrication, or stamping. Special insulating fenders or plates protect the blades against accidental strip impacts.
In such a way a better viscosity control and costant fine automisation of the oil are obtained. Available with a variety of features. Example of special design wlectrostatic enclosures for the Temper mills where very little space is normally available on top of the recoiler, and a very high oil output is requested.
The opposite polarities electrostatic charging system we are now proposing as standard avoids over oiling the strip edges and greatly reduces the escape of oil mist from the enclosure pass line windows.
