A steel strip electrostatic oiling machine is designed for
The electrostatic oiler given by the engineering company ENCE GmbH (ЭНЦЕ ГмбХ) as an example is capable of overall spreading of oil over the top and bottom sides of a horizontally moving strip.
The functional principle of a strip electrostatic oiling machine is that it employs electrostatic forces from knife edge electrostatic charge to spread. The latter disperses the oil to the drops of small diameter when contacting it as a liquid of electrical resistance. The electrostatic oiling procedure, as opposed to high pressure air/liquid nozzle spraying, ensures a more accurate and even layer due to
Steel strip electrostatic oiling system offered by the engineering company ENCE GmbH (ЭНЦЕ ГмбХ) can be used only with electrically
Electrostatic body is made from a steel sheet. Body base has an inclination towards the outlet for residual oil collection into a tray. Entrance doors are provided at both end of the body. The entrance doors are equipped with electrical/mechanical safety interlocking devices and polycarbonate sight holes.
Electrostatic oiler due to its construction can be put out of line if its application is not needed. Electrical motor and chain system together with big heavy duty wheels ensure the oiler
One splash aluminum shear unit is on top of the path, the other is at the bottom. Shearing units will be mounted on the telescopic roller carrier mechanism.
The bottom shearing unit is protected with the polypropylene edges applied to the casing. The tables support the strip when it is charged and run out of the casing and in case of voltage loss.
A servodrive is used for metering pump control. The PLC algorithm creates a line velocity basic signal to secure the proper oil quantity supplied to the shearing unit. The algorithm refers to the line velocity, the shear width and the
Sprinkler doors are equipped with electromechanical high voltage disconnection interlock when open.
The scope of supply includes two solid high voltage power supply units. The power supply is a single solid unit with various output voltage values up to 125 kW. The unit with the plexiglass front panel on top of the main sprinkler body is completely integrated.
PLC software for steel strip oiling system was designed to monitor the oil flow quantity through the oil flow monitoring system. It provides the automatic voltage adjustment to make it most effective with reference to the line velocity and

The control equipment for the oil heating unit is installed in an electric cabinet for easy access. Piping inside the knives creates a heat transfer
The steel electrical control cabinet is NEMA 12 enclosure. It accommodates a PLC, servodrive controls, main circuit breaker and fuses. The electrical cabinet contents are
All control devices are built into the control panel top surface. The control panel has an
Expansion tank column structure is complete with one carbon steel expansion tank. The tank is equipped with a sight glass for level indication. The min. and max. level switches transmit the signal to the transfer pump.
Noncontact immersed heaters perform heating, for which emptying the tanks during cleaning or replacement is not required. The heaters are controlled by thermostats needed to sustain the suitable temperature viscosity of the surface material for ensuring optimal conditions for coating.
The tank filter is used for filtering the oil coming to the tank. Coarse double filters are used for filtering at the proportioning pump inlet as well as for reclaimed material.
The oil tank is installed on the common base with proportioning pumps, filters and oil reclaiming pump. All electric connections are prewired in the connection box.
«Standard» interface signals which are created between the strip oiler and the main controller (central control board) operating on the line are transmitted via analogous and digital Inputs/Outputs.
Apart from steel strip oiling system, ENCE GmbH engineering company (ЭНЦЕ ГмбХ) delivers through its widespread network of the representative offices in Russia (Moscow, N. Tagil, Lipetsk, Cherepovets), Ukraine (Kiev), Uzbekistan (Tashkent), Kazakhstan (Almaty, Atyrau) a broad range of equipment and accessories for sheet rolling, hot galvanizing lines and strip polymer coating:
