WATER COOLED BLOWER

The basic concept is as follows: the process begins with air flowing from the inlet port to the chamber of the element. The timed rotation of the rotors against the chamber wall produces the so-called "air flow direction." These chambers do have ambient pressure.

The machine pressure is changed as soon as the first lobe passes the opening to the pressure side. It's called isochoric compression. The rotors seal each other to the inside, preventing a change of pressure. The output of the theory of compression is as follows. Positive displacement blowers are powered using the isochoric compression concept, also known as external compression. The increase in pressure is achieved by the irregular transport of the gaseous medium (e.g. ambient air) to the device.

By forcing the medium from ambient conditions to a structure with a certain resistance. The blower will work at a controlled output level in order to overcome this resistance.

The rotors are synchronized by a timing ratio of 1:1, which is located at the end of the shafts. Bearings are mounted externally in a compression chamber with an oil lubricated device. The drive shafts have labyrinth-style oil seals, so named because of the labyrinth of grooves that the oil must pass through. The splash lubrication system uses fine oil mist for lubrication.

Heavy Duty Blowers are based closely on the original design of the Roots Styles blower, with its renowned durability and life expectancy.

DESIGN FEATURES

The conservative load-bearing capacity of the larger roller part bearing diameter ensures an extended operating life. Timer life of the gear is also extended by controlled lubrication systems. Computer computed impeller profiles ensure optimum volumetric performance with limited absorbed power without compromising torsional rigidity. The high rigidity of the impeller/shaft allows a higher pressure increase to be achieved than for other devices of comparable scale. The generous diameter of the shaft keeps the drive tension mild. Gear and shaft strength is greatly improved by the use of taper/straight mounted gears that do not need keyways to be positioned.

Setting the gear wheels to achieve the proper timing of the impellers is simplified, a function that encourages field maintenance. Precision ground and hardened steel gears are used to ensure smooth, quiet operation and precise timing of rotating thrusters. A managed lubrication system is provided to ensure efficient operation without energy waste in the gearbox. In the gear case, specially crafted rotary oil seals are used. This function avoids maintenance related to the use of lip seals. Plan and manufacture shall be in compliance with metrical specifications. When used as an exhaust and dust or liquids might be drawn into the machine due to a lack of filtration, closed end rotors should be specified. This minimizes the chance of loss of dynamic equilibrium due to material within the rotors.
