Pneumatic conveying or pneumatic transport is a system or a process in order to transfer the bulk materials whatever they are granular or powdered through pipeline using pressured or vacuumed gas (usually air) which is generated by a suitable roots blower or compressor.
Roots blowers are both employed to aerate grit chamber in order to prevent sinking to the bottom of wastewater and blow air to aeration unit for bacteria to live in water treatment units. Number and size of blowers should be selected according to the capacity of the facility.
Roots blowers are employed in chemical and petro-chemical industry for conveying and compressing of many kind of gases that are inert, corrosive and explosive. Besides, the chemical and petro-chemical industry particularly depends on the gas supplying for their processes.
Foods must be clean and healthy. Therefore, both raw materials and finished products should be zero-touch during production. Blowers provides to convey pneumatically both raw materials and finished products like as sugar, salt, flour, grains, milk powder, chocolate etc. by reliable and clean way.
Rotary air blowers are used as supercharging of diesel engine, providing air supply to bubbler systems to Arctic duty vessels and icebreakers, for pneumatic transportation on ships, for maintaining ice-free ports, providing air bubble curtains (creating sound protection) to protect marine life.
Roots blowers are used in mining industry for pneumatic transport of bulk materials and minerals. It is also used in aeration for oxidation processes and other refining applications. And especially big mining areas have wastewater treatment facilities where the roots blowers are employed.
Roots blower is almost used in vacuum systems where large gas loads are pumped in the intermediate vacuum range and/or volumes must be evacuated in a relatively short time. Vacuum systems are used in different manufacturing processes in many industries and areas.
Biogas is primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulfide (H2S), moisture and siloxanes. Biogas is explosive and corrosive. Roots blowers are used to convey biogas through pipes to burner or recirculated to fuel combustion engine-driven machines.
Roots blowers are also used as mobile. Roots blowers are mounted on bulk trailers in order to blow feed, grain or cement from the trailer into bulk hoppers, bins or silos. They are also used to blow feed, grain or cement from hoppers, bins or silos into trailer.
Easy installation, excellent design, problem free operating, low maintenance, endurance against to hard working conditions are some significiant features of Pasifik Blowers.
Because of highly-developed design of Pasifik Blowers that are suitable for extensive range of industrial applications and hard working conditions.
Wide range of our Roots Blowers and accessories are available depending on process parameters and operating environment. Our six models are ready to serve you.
We engineered our machines to outperform and provide you with years of easy upkeep. We deliver more reliable and efficient roots blowers to you thanks to its rigid cast iron casing.
Overheating of most machines is generally undesirable situation. We prevent to overheat thanks to ribbed blower body for high efficiency heat dissipation.
We at Pasifik Blower produce every single parts of our blowers by ourselves. What parts of our blowers you need, we guarantee that we can quickly supply it.
Because the rotors operating non-contact each other and blower housing, no lubrication is required. This feature provides a great advantage in applications that need clean air or gases.
You will find here issues that are most curious about Roots Blower, pressued air or gases, some technical subjects about compressors. How do roots blowers work? What is positive displacement?
Roots Blower is consist of two rotors inside the pump housing. The two rotors are mounted on parallel shafts. Rotors rotate non-contact at the same speed in opposite directions in order to draw air or gas into the blower body. A set of timing gears keeps the rotors in synchronization. Driving air or gas at the inlet side is trapped between the rotors and the casing. The rotating rotors pushes the trapped air or gas to the discharge side against whatever pressure exists in the system.
Driving and Driven Rotor
One rotor is called the “driving rotor” because it is run by an external power supply – generally an electrical motor-, while the opposite rotor is called a “driven rotor” because it is driven by gears connected to the driving rotor.
Once the rotors open to the outlet side, the discharge line equalizes the pressure of the air and is forced out of the blower. The air is unable to come back due to the small amount of internal clearance between the internals of the machine. This process enables the blower to overcome line pressure hence the name positive displacement. Put differently, the volume of air does not change within the device, but is rather displaced from one end of the machine to the other.
The compressors are divided into two parts:
1.Dynamic Compressors
a. Axial Compressors
b. Centrifugal Compressors
2. Positive Displacement Compressors
a. Roots Blowers
b. Reciprocating Compressors
c. Screw Compressors
Air whose density is increased by subjecting it to a pressure greater than atmospheric pressure.
The property of a substance capable of being reduced in volume by application of pressure; quantitively, the reciprocal of the bulk modulus.
Volume flow rate measurements are necessary in many industrial processes to keep track of the amount of material being transported from one point to the next point in a plant.
The volume flow rate is simply defined by the volume of a given substance that flows through something per unit time.
volume flow rate = volume/time
