Aeration fan: The process of forcing air or other gases into water or liquid through conveying equipment and diffusion equipment by using a blower with a certain amount of air and pressure is called blast aeration. The fan with this purpose is called aeration fan.

Characteristics of aeration fan:

(1). Has a certain amount of wind. The purpose of aeration is to increase enough dissolved oxygen in water or liquid to meet the oxygen demand of aerobic organisms.

(2). with enough pressure. The blower aeration process is the transfer process of molecular mass between gas and liquid. To make the gas fully diffuse and contact in the liquid and prevent the suspended matter in the liquid from sinking, the aeration fan must be able to generate sufficient pressure.

The main application areas of aeration fan:(1) aquaculture blast aeration.(2) water treatment blast aeration.

Roots vacuum pump is a commonly used equipment in enterprises. During normal use, we need to understand the structure and transmission mode of the equipment. Below, let us understand together!

1. The overall structure of the pump

The arrangement of the pump body of the Roots vacuum pump determines the overall structure of the pump. At present, the overall structure of Roots vacuum pumps at home and abroad is roughly three:

(1) The intake and exhaust ports of the vertical structure are placed horizontally to make the assembly and connection of the pipeline easier. However, this pump has a high center of gravity and poor stability during high-speed operation, so this type is mainly used for small pumps.

(2) The air inlet of the horizontal pump is at the top and the air outlet is at the bottom. Sometimes, in order to facilitate the installation and connection of the vacuum system pipeline, the exhaust port can be connected from the horizontal direction, that is, the intake direction and the exhaust direction are perpendicular to each other. At this time, the exhaust port can be opened from the left or right, except for one end of the exhaust pipe, the other end is blocked or connected to the bypass valve. The pump structure has a low center of gravity and good stability during high speed operation. Usually, large and medium-sized pumps use this structure.

(3) The two rotor shafts of the pump are installed perpendicular to the horizontal plane. The assembly gap of this structure is easy to control, the rotor is easy to assemble, and the pump occupies a small area. However, the center of gravity of the pump is high, the disassembly and assembly of the gears are inconvenient, and the lubrication mechanism is relatively complicated.

2. Drive mode of pump

The two rotors of the Roots vacuum pump operate relatively synchronously through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling. There are two main types of the layout of the transmission structure: one is that the motor and the gear are located on the same side of the rotor, and the driven rotor is directly driven by the gear at the motor end, so the torsional deformation of the drive rotor shaft is small, and the gap between the two rotors will not change due to the large torsional deformation of the driving shaft, so the gap between the rotors is running the process is uniform. The disadvantages of this transmission mode are: a. there are three bearings on the driving shaft, which increases the difficulty of processing and assembly of the pump, and it is inconvenient to disassemble and adjust the gear; B. the overall structure is uneven, and the center of gravity of the pump is biased to one side of the motor and gear box.

The other is that the motor and transmission gear are installed on both sides of the rotor. This form makes the overall structure of the pump symmetrical, but the torsional deformation of the driving shaft is relatively large. In order to ensure that the rotor has a uniform gap during operation, the shaft should have sufficient rigidity, and the connection between the shaft and the rotor should be tight. This structure is easy to disassemble and assemble, so it is widely used.

roots blower:

Roots blowers are one of the more popular operating ventilators. The original two-leaf Roots blower has been replaced by the current three-leaf, low-noise, environmentally friendly three-leaf blower. Traditional air-cooled, single-tank Roots blowers have gradually developed low-noise, double-tank, water-cooled, oil-cooled Roots blowers and other new products on the market. What issues should be paid attention to in the initial stage of buying a Roots blower, let us take a look:

Let's take a look at the Roots blower: its structure is so simple, it consists of a shell, a wall plate and two three-bladed wheels. Through the action of a pair of synchronous gears, the two impellers rotate in opposite directions and at the same speed, and rely on the tiny gap between the impeller and the impeller to basically isolate the suction cavity and the exhaust cavity, and the impeller rotates to push the casing The volume of gas achieves the purpose of blowing.

Roots blower adopts frequency conversion control, which can accurately control the air volume. Compared with valve control, it is more intuitive and convenient to adjust the air volume of the fan to meet production needs. Due to the use of frequency conversion technology, the motor realizes soft start without the influence of starting current. When the inverter is not used, the motor will start directly, and the starting current is as high as 200 --- 300A, which will adversely affect the motor or the power grid. Now, using the soft start of the inverter, the starting current is not higher than the rated current 46A, which can reduce the impact of the fan outlet pressure on the fan due to the instantaneous increase of the fan outlet pressure, thereby extending the service life of the fan. Blowers and other equipment; because the fan speed is reduced to 60% of the original, the vibration frequency of the fan pipe is greatly reduced, the original basic noise of the fan is reduced, and the mechanical life of the fan, motor and bearing can be extended, and equipment maintenance can be reduced.
