Application of Encom inverter in various lines
Characteristic of modern frequency conversion speed regulation is the high efficiency with no additional slip loss brought by speed regulation but with large speed regulation range, high precision and belongs to stepless speed regulation. ItĄ¯s easy to realize direct and closed-loop control. The inverter is specially suitable for technological alteration for the old equipment as previous mouse cage motor can also be utilized in frequency conversion speed regulation system. It not only remains merits of the previous motor which are simple configuration, reliable and durable and easy to maintenance, but also can reach outstanding power saving effect. Therefore, the inverter is an ideal selection for power saving of blower and water pump.
InverterĄ¯s application to plastic machines
In the process of manufacture of plastic products, itĄ¯s often needed to regulate speed of the production machines due to characteristic of the plastic, various specification of the products and different demand from production craft. The technology of frequency conversion speed regulation has been mature as electric power and electronic technology developed rapidly and the frequency conversion speed regulator has been widely applied in various lines. Its merits of smooth stepless speed regulation, high reliability, high precision, power saving and automated level increasing etc., have raised automated level of plastic machines in certain degree which impelled development of plastic line.
InverterĄ¯s application to paper machines
Papermaking enterprise is the high energy consumption enterprise. To produce a ton paper will consume electric power of above 500 kwh, which is a very large number. And above 50% of the equipment belongs to the load kind of blower and water pump. Basically these equipments utilize valve or baffle to regulate air or liquid flux at present and large amount of energy is consumed for the valve and baffle. To regulate with the inverter, you can reduce loss massively and get very obvious economy profit from power saving, which is worth promoting vigorously by enterprises.
InverterĄ¯s application to power saving of injection molding machine
Injection molding machine is the kind of device which finishes one-time injection molding for the work piece by injecting liquid plastic into cavity of tooling after various plastic is heated, melted, mixed and pressure boosted. Its working procedure process is basically the same which can be divided into 7 sections: locking the tooling, shooting plastic, keeping pressure, melting plastic, cooling, opening the tooling and ejecting pins. Each working procedure demands different pressure and flux, in other words, the processed work piece isnĄ¯t always in max. pressure or flux and its pressure and flux are regulated through adjusting opening angle of pressure proportion valve and flux proportion valve. However, oil pump motor works at constant speed and input power of oil pump in each working process doesnĄ¯t change much. ItĄ¯s not only economic but also practical to realize regulation for pressure and flux by adjusting speed of the motor(oil pump) with the inverter.
Application of frequency conversion speed regulation technology to the boiler
To increase control level for input air of boiler and to reach power saving effect, itĄ¯s the first choice plan to adjust input air in frequency conversion speed regulation mode. You can regulate speed of the blower at any moment according to variation of needed quantity of air with frequency conversion speed regulation mode, which reduce pollution to the environment by the noise(the motor run at speed blow rated one with reduced noise of the wind) and react on enhancing industrial hygienic level in certain degree. Bearing of motor and blower isnĄ¯t easy to damage which prolongs its lifetime for the blower run at speed below rated one long. Heating quantity of the motor reduces, repair reduces, shutdown time reduces and a lot of maintenance cost is saved.
Application of inverter to constant pressure water supply
Constant pressure water supply is the water supply mode of constant outlet pressure when water consumption in water supply network varies. Outlet pressure of the water supply network is decided by customerĄ¯s demand. Traditional constant pressure water supply mode is realized through water tower, top water tank and barometric pressure pot etc. Along with day by day mature and widespread application of frequency conversion speed regulation technology, you can make up of control system by combination of inverter, PID adjuster, single-chip microcomputer and PLC etc. to adjust output flux of water pump so that constant pressure water supply is realized.
Application of inverter to central air conditioner cooling pumps
Adopt compressor to force refrigeration to circulate in order to shift the heat inside construction into cooling agent through cooling medium(generally water), and shift the heat into air by cooling tower. This is basic work principle of central air conditioner. Thereinto energy consumption of cooling pump and freezing pump is about 60% of general energy consumption. All the air conditioning apparatus are designed according to maximum refrigeration quantity of designed operating situation while they work at small load in most of time. Therefore, to use inverter to drive air conditioner will save a large number of energy. |
