I. Overview of rotary fan products 1. From the perspective of air volume, it belongs to small blower. It belongs to medium pressure blower from the pressure range. It belongs to water treatment aeration blower from main use.
2. The rotary fan consists of the main unit, base, motor, pulley, air chamber, air filter, drip nozzle and other components.
3. The main body of the rotary fan is cast from cast iron, 2 metal rings (or 8 springs), 1 main shaft, 1 rotor, 4 slides, 1 eccentric cylinder, and 2 pump cover. Fan metal ring, rotor, slide, pump cover
The eccentric cylinder is made of wear-resistant castings, and the main shaft is made of 45# steel.
4, the rotary fan 4 sliding blades are embedded in the aliquot of the rotor, the rotary fan shaft is fastened in the center of the rotor, the two ends of the shaft are equipped with bearings and the front and rear pump cover are connected to the eccentric cylinder, at this time the rotor With 4 roots embedded
The sliding piece in the rotor and the inner wall of the cylinder form four spaces of different volumes. During the operation of the rotary fan, the metal ring or the spring pushes the sliding piece to move uniformly along the inner wall of the cylinder, and the rotary fan cylinder is driven by the suction port. Suction port
The air guide groove, the exhaust port and the exhaust port air guide groove. The working process of the rotary fan is composed of three parts: the suction stroke, the compression stroke and the discharge stroke. When the rotary fan rotates, four of the rotor slots are made. Slider reciprocating
Exercise, sucking in, compressing, and discharging air to form a fan.
Second, the working principle of the rotary fan:
1. The rotary fan rotates eccentrically by the rotor biased in the cylinder, and causes the volume change between the blades in the rotor groove to suck, compress and discharge the air. Automatically lubricate with the pressure difference of the blower during operation
The oil is sent to the drip nozzle and dripped into the cylinder to reduce friction and noise while keeping the gas in the cylinder from flowing back.
2. The four sliding blades of the rotary fan are embedded in the halved rotor. The fan shaft is fastened in the center of the rotor. The two ends of the shaft are equipped with bearings and front and rear pump covers connected to the eccentric cylinder. At this time, the rotor and the four Embedded in the turn
The sliding piece and the cylinder in the sub-division form four spaces of different volumes. During the operation of the rotary fan, the metal ring or spring pushes the sliding piece to move uniformly along the inner wall of the cylinder, and the rotary fan air flow passage has a cylinder suction port. Inhale
The air guiding groove, the exhaust port and the exhaust port are composed of air guiding grooves.
3. The working process of the rotary fan is composed of three parts: the suction stroke, the compression stroke and the discharge stroke. When the fan rotates, the four sliding pieces in the rotor slot reciprocate, and the air is sucked in, compressed, and discharged.
. Therefore, the fan is also called a slide fan.
Third, the main purpose of the rotary fan:
Water treatment blast aeration, hospital sewage aeration, vacuum feeding in the printing industry, domestic sewage, industrial aeration, aeration, plastic welding, air supply, burner spray, glass industry
, aquaculture, other equipment that requires gas.
Fourth, the characteristics of the rotary fan:
1. Small volume, large air volume, low noise and energy consumption. The rotary blower adopts the principle of operating compressed air. Although it is small in size, it has large air volume, energy saving and quiet operation. It is unmatched by other types of fans.
of.
2. It runs smoothly and is easy to install. When the small model is in operation, as long as it is properly placed, the vibration is small, and it is not necessary to install an anti-vibration device, which is convenient to install.
3, anti-load changes, stable air volume. For example, if the pressure of the sewage treatment aeration tank changes, the load changes, but the air volume changes little with the pressure change.
4. With an air chamber, the air is stable. All models are equipped with an air chamber to prevent air pulsation and smooth air.
5, excellent material, clever structure, excellent performance. The blowers are all made of high-quality materials, with exquisite structure, sturdy and durable performance, and long-term use failure.
6, the maintenance is simple. Low speed, low wear and long life.
V. Rotary installation 1. Pay special attention to safety when handling the rotary blower. Avoid the bumper and impact of the rotary blower, and do not put the rotary blower up and carry it to prevent the lubricating oil from pouring out of the fuel tank.
2. The fan room should have a venting port and a ventilation fan. The venting port should be placed at the upper and lower sides to facilitate air convection to prevent the temperature in the machine room from being too high and affect the normal operation of the rotary blower.
3, around the inner wall of the machine room is equipped with sound-absorbing materials to reduce noise.
4. The rotary blower should be installed horizontally.
5. The diameter of the gas distribution pipe should not be less than the air outlet diameter of the rotary blower, and pay attention to the inside of the pipe. The air supply pipe should be installed above the water surface to prevent the water in the pipe from causing excessive pressure at the start.
6. Be careful not to knock the check valve down when taking over (the raised portion of the check valve should face up).
7. Please connect the distribution line correctly and note that the motor steering is consistent with the rotary direction of the rotary blower.
8. When two rotary blowers are used alternately, the starter fan should be avoided frequently in a short time. It is hoped that the continuous running time of one rotary blower is not less than 12 hours.
