Yes. The air closer is an important device in the pneumatic conveying and ventilation dust removal network. Its main function is to continuously and timely discharge materials into the unloader or dust collector, while preventing outside air from entering the inclined loader or dust collector. It is widely used in pneumatic conveying of rice milling, flour milling, animal feed, machinery and chemical industry, medicine, tobacco, metallurgy, cement dust removal and other industries. other industrial equipment and unloading the pressure state of the pipeline network.
What is the relationship between calculating the discharge volume of a rigid turbine feeder and the number of revolutions?
Air closer is also known as star unloader, ash discharge valve, fan, rotary feeder. Usuallynt, the structure of the air closer is composed of a rotor wheel with several blades and a shell. It consists of body, joints, reducer, motor, etc. The inlet and outlet flanges are type A and the round flanges are type B. The air shutter is usually installed at the bottom of the dust collector hopper to ensure this. the connection is waterproof and airtight. The upper part must always maintain (store) a certain height of dust.
The air seal is not closed properly
The rigid impeller valve is an important component commonly used in pneumatic conveying systems. As an important accessory in pneumatic conveying equipment, it is necessary for us to summarize the selection basis and model classification of rigid turbine feeders: We can calculate rigid turbine feeders according to their rotation speed and their discharge volumee per turn. Total flow per hour can. get your most ideal selection result.
The speed of rigid turbine feeder can be divided into the following types: 17 rpm, 21 rpm, 25 rpm, 32 rpm, 35 rpm, 43 RPM, 51 RPM, 60 RPM, 65 RPM, 88 RPM. , 134 rpm, 164 rpm and other specifications.
The corresponding single machine speed ratios are: 87, 71, 59, 47, 43, 35, 29, 25, 23, 17 , 11, 9 and so on. we. kind.
The most commonly used rotation speeds and gear ratios are: 21 rpm, 25 rpm, 43 rpm, etc.
Capacity discharge from the rigid turbine feeder (air shutter). ) Calculation method:
V(m3/h)=V1(L/rev)xN(rpm)x60x η（%）
G（T/h）=V（ m3 / h) xρ (T/m3) xK
V: Discharge volume (m3/h)
V1: Rotor volume per revolution (L/rev)
N: Rotor speed per minute (rpm)
η: Rotor volumetric efficiency (%)
ρ: FromMaterial apparent density (T/m3)
K: The correction coefficient is generally 0.7 ~ 0.8
The rotation speed of the rigid turbine feeder directly affects the discharge volume of the unloader, and the rotation speed of the rigid turbine feeder is determined by the motor. Therefore, the motor is also a very important factor to consider when selecting a rigid turbine feeder.
There are two aspects to consider if the air closer is leaking:
1. If the connection between the air closer and the unloader is leaking, check the connection method.Lanpan.
2. Is it because the air closer rotor is worn out, causing a large gap and loose air closing?
3. If the air closer rotor is worn and the gap is large and the air is not sealed tightly, you need to replace the air closer.
