pu foam machine EMM078-A20
1. Summarization
The EMM078 series High Pressure machine is that our company follows the international’s advanced technological products, The Main parts are imported from foreign countries, technical and safety performance of the equipment has reached the advanced level of the same product of the same period abroad.
When developing the EMM series high pressure machine, Technology with the "best practices" "plug and play", all of the machine’s parts and module are installed at one frame, component’s pipes short, pressure small, precise at the temperature control, optimization of the control technology, improve the equipment’s reliability and the production’s quantity.
The EMM078-A20 High pressure machine has 1 POLY. barrel and 1 ISO. barrel, and two metering units drive
by independence motors, through changing the metering pumps output to change the pumps output. This kind of machine is specially used in the polyurethane pouring products.
2. Main parameters and descriptions for the equipment
2.1 Type: EMM078-A20
2.2 Suitable foaming system: soft foam, hard foam, simi-hard foam
2.3 Suitable material viscosity (22°C):
polyol : max. 800-6000 mPs
isocyanate: max. 5-200 mPs
2.4 Pouring output: 50~300g/s (1:1), with ratio range adjustable 5:1~1:1
2.5 Pouring program time: 0.5~99.99sec
2.6 Inject the quantity of the procedure:
Manual inject: 9
Automatic inject: 99
2.7 Metering unit: Measurement accuracy≤0.5%
Component material | POLY. | ISO. |
Quantity | 1 | 1 |
metering pump type | A2VK12 (12cc/rev) (Gelanrex ) | A2VK12 (12cc/rev)
|
Shift motor | 5.5 | 5.5 |
Speed(RPM) | 1450 | 1450 |
pump sealing lubricating | Magnetic coupling (Maintenance-free) | Magnetic coupling (Maintenance-free) |
All the parts such as Shift motor, Gear metering pump, Bracket, Coupling is using to metering the components’ flowout.
2.8 Working pressure limit and control system
Both polyol and isocyanate side working pressure are allowed in a range of 6~22Mpa. Whenever the working pressure exceeds the range, the pouring operation will be stopped automatically and an alarm message of < working pressure abnormality > will be displaying on control panel at the same time.
The limit pressure of the metering pump is pre-settled as 25Mpa and with mechanical & electrical safety protection:
--- Mechanical protection: the relief valve function open whenever pressure reach 25Mpa,
--- Electrical protection: the metering unit emergency stop, audio alarm, and a message of <pump over pressure> display on panel screen.
The POLY. metering pump inlet pressure protection is pre-settled as 0.25Mpa, and the ISO. metering pump inlet pressure protection is pre-settled as 0.15Mpa. Whenever the inlet pressure lower than the preset value, the metering unit emergency stop, audio alarm, and a message of <pump pre-pressure too low> display on panel screen.
2.9 Components’ flow output control and testing units
Bases on the pump’s flowout and the components’ mixing inquery, set two parameters in the pouring course; the two metering units are drived by two independence motors , through change variable high-pressure displacement of the metering pump’s flow out to control the metering pump’s output.
2.10 Component filter:
Two components furnished with filter separately, and the filters’ precision is 330μm. Rotate the axle of the filter and fixed blowdown regularly.
l Out of the filter with digital pressure switch to protect the metering pump.
