Oiling Spraying System

Description

The SYRO Oil Spraying System is one of the most innovative products that we can offer as a supplier of the fibre cement industry. Due to its veritable efficiency and therefore very low oil consumption it actually revolutionizes the oiling of steel moulds/templates in the fibre cement and wood cement production. And this all without any negative influences on the release of your fibre cement or wood cement pressure panels, plates or slides from the used steel moulds/templates. Compared to common oiling methods the oil consumption is much lower with the SYRO Oil Spraying System!

 

 

Advantages on a glance

  • Very low oil- or release agent consumption.For the production of fibre cement or wood cement pressure panels, plates or slides sensational 4 g/m2 to 8 g/m2 are enough with the SYRO Oil Spraying System, and not 15 g/m2 to 30 g/m2 as with common oiling methods. Due to individually adjustable spray valves almost every spraying picture and any quantity of g/m2 can be set.

  • Highly economical efficiency

  • Very fast Amortisation
  • Ecologically harmless
  • Easy installation and operation.Even smallest areas of 200 x 50 mm can be spray coated and there are no constraints for the maximum width. The SYRO Oil Spraying System maybe used for any coil or mould widths. Due to an initiator mechanism even moulds with a high throughput speed of 1 to 3 m/s can accurately be spray coated. Our system is very flexible and we can offer a wide range of different nozzle sizes especially for oils with less viscosity. Only diesel or oils containing huge amount of greases and saponifications may not be used in order to not obstruct the nozzles of the spray valves!
  • flexible System
  • highly efficient and precise
  • easy operation and maintenance

Application

The SYRO Oil Spraying System is primarily used for the efficient coating of running steel or aluminium coils in the steel moulds/plates production and for the coating of all kind of steel moulds in the fibre cement or wood cement pressure plates manufacturing and in the concrete roof tile production.


Spray Bars

The spray nozzles are assembled on two spray girders made out of 3 precision steel tubes. The spray bar consists of two horizontally spray girders, which are assembled on two racks mounted on the ground. One spray girder is for the oiling from above the other one for the oiling from beneath. The required distance to the throughput level is pre-installed factory-made. The air and oil supply happens separately for the above and bottom spray girder. Below the bottom spray girder an oil drip pan is installed.

 

 


Spray Valves

The spray valve basically consists of body, valve with needle and flat stream cap with collar ring. There are 3 separate inlets for the oil, the spray air and the control air.

 
The spray valve works pneumatically and is opened and closed by a needle that is controlled by the control air. Depending on the needle stroke, the outlet diameter and the flow rate of the valve is adjusted. With the adjusting screw it is possible to adjust the needle stroke in order to either increase or decrease the oil flow rate. The spray width of each valve is approximately 100 mm.

 
The switching-on of the control air opens the spray valve by lifting the piston with the needle against the needle spring. The oil starts to flow out the valve and is atomized by the spray air if it is opened as well. If the control air is switched-off the needle spring closes again the valve with the needle.

The spray valve is self-cleaing as the needle foraminates the entire valve head if the valve is closed. Eventually adhered dust particle are ejected this way and the spray valve is neither bordering nor jamming.

The spray air is switched-on before the valve opens and is switched-off after the valve has closed again. This way the spray stream starts immediately and on the other hand the spray valve is blown out after it has been closed again. Oil drops are so avoided after the spraying.


Spray Chamber

The spray chamber encloses the entire spray bar and has the goal to avoid any oil mist. With time accumulated oil within the spray chamber is collected by a drip pan and can be discharged at any time.
The spray chamber is a mould construction from which the top can be easily removed, so that the spray valves are freely accessible. Further the chamber consists of two slits for the steel template throughput, which are variably closable with strips.

Optional: Electrostatic Suction with Filter

Additionally to the spray chamber that already very efficiently avoids the environment from being polluted by aerosol it is possible to complete the SYRO oil spraying system with an electrostatic suction device.
