growing in recent years energy prices have meant that more and more people are beginning to ask themselves: How much will operate the camera after purchasing it?
That is why in this article we have decided to further explore the cost of operation of the spray booth.We do not dwell on the issue of cleanliness in the chamber, as well as permanent and periodic servicing expensive equipment, since these issues should be for all users of cameras such as obvious as the periodic cleaning of the dwelling and its repair.
This paper proposes consideration of the problem of power consumption in the operation of painting chambers.
So, what's new in technology painting tanks?Frankly speaking - nothing.Most structural solutions - are known in the market.Let's start with a solution that is very important for all present and future members.It's about the use of inverters.
Suppliers painting tanks are beginning to offer motor control using inverters (frequency converters, then - IF).This is especially true camera large painting of cars, buses, with powerful engines from 11 kW and burners (350kVt).Then the use of such equipment brings concrete and tangible benefits.The principle of this solution is very simple, but in practice the implementation of such a system is not so simple and obvious.The algorithm is given below.
After entering the bus or in the car painting chamber made its preparation for painting.In this phase of the fan at full power is not feasible, since the cabin is required only maintain the operating temperature.In this mode, the drive will automatically reduce the power of the fans up to 30-40% (10-20 thousand m3).With such a burner air passes will consume a moderate amount of fuel.Electric motors will also consume much less power.
Then begins the process of applying the paint.There have required more air (24-26 thousand m3) in order to retain a multiplicity of air exchange in accordance with the instructions.In the painting of the drive motors includes 80-85% of optimum capacity.
Again do not need the full power of electric motors, and thus again saving energy.The burner will operate at lower levels, which also leads to savings in fuel consumption.
If necessary, more power (winters), we have an adequate supply of power, providing peace of mind.
Ventilation mode spray booth after painting is particularly important, especially when it comes to water-soluble paints.In this case, you must bring the maximum amount of air preheated to a temperature of 20-30 ° C.Programmed mode purge the drive includes an electric motor at full capacity (30-35 thousand m3) for maximum air supply.This phase lasts 5-10 minutes, and only in this case, the total power required.
After applying all layers of paint drying phase begins.Again, for this mode requires 50-60% of power ventilators.The level of the air virtually the same as in the color phase.It should also be noted that manufacturers modern painting chambers with inverter technology combined operation of the burner and engines into a single automated process, which enables the camera heat up to 60 ° C in a very short time, resulting in cost savings there.
After the drying process, the phase of cooling.The modern equipment has the cooling mode.In this phase there is no need to use the full capacity of units.IF limits the power of the work up to 30-40%.
IF - expensive devices, the use of which is not always appropriate.Experience and practice shows that by using a 7.5 kW motor and burner 220kW installation costs and the application of the drive will be repaid only after 4-5 years.For motors of 11 kW and 350 kW burner return to be about 18 months due to energy consumption.
course, the more cycles performed in the chamber, the faster the return on the inverters.These relate to the production, carrying out at least 15-20 cycles per week.
