Dear all,
We are having sand mills with a motor capacity of 30 HP. As the sand settles during shutdown, it requires a huge initial torque to start the sand mill. Presently, it is having star-delta starter.
The motor loading percentage in delta is around ~ 50 percent. The sand mill runs for a...
"The second thread I referenced above has the math to determine the discharge temperature of an oil-flooded screw compressor and it is pretty messy. There is a lot to it, but trying to fix a gas temperature problem by cooling the intake air or cooling the air on the outside of the fin-fan cooler...
Dear all,
During last summer we have faced frequent issues of discharge Air temperature high in Rotary screw oil lubricated single stage air compressors(Rated Pressure 8 bar,500 CFM, 75 KW) because of summer heat.
Can we use air conditioned (cooling coil)dehumidified space to reduce suction...
Hello everyone,
I have to select a pump giving Q flow and maintaining P line pressure. How to calculate the head required for the pump. The pump rated head minus TDH responsible for line pressure?
I have below questions. Please help
What will be the line pressure P at the delivery of a...
Dear all,
PDP is the dew point temperature at that particular compressed air pressure. But how do we know the dryer is delivering moisture free air by seeing the PDP (degree celsius) in dryer HMI.
Also please explain me how the PDP value is measured in a dryer?
Thanx in advance.
Hello,
I have the source (air receiver) pressure more than 7 bar. I have connected a 1 inch regulator in between receiver and machine. I have observed 7 bar pressure at the regulator and set that to 6.5 bar. Now I started the machine (which consumes 40 cfm) and I observed the pressure at...
Thanks for your reply :)
The application is we are required to maintain high Rh and low temperature in glass fiber forming.
The water header spray pressure is constant.

Any different beahviour during winter and summer season?
I have seen a Water spray Air Handling Unit used for cooling and humidification and cleaning of air. Cleaning is done when the air passes through the sprays.
Air handling unit consists of air filters, sprays,a pump to circulate the water to the spray header,a heat exchanger to cool the spray...
