I. Introduction of centrifugal blower
Centrifugal blower is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine.
The two-row large-spacing cupola with the latest design and conforming to the “three modernizations” standard is a kind of cupola commonly used in the domestic foundry industry. When the distance is large, the bottom coke burns to form two independent combustion zones. By extending the superheating zone, the hot metal superheating distance and the intense burning of the bottom coke are increased, the furnace condition is stable, the molten iron temperature is high, and the quality of the molten iron is good.
According to the air supply temperature, it is divided into two structures: cold air and furnace hot air. Different smelting requirements are achieved by adopting different temperature air supply. Furnace hot air type uses dense rib furnace heat exchanger to heat the physical heat in the furnace gas into the furnace cold air. The hot air temperature is about 180-250 ℃. It has the advantages of not occupying the workshop production area, compact structure, convenient operation and small thermal inertia. Features.
2. Installation steps and instructions for centrifugal blower
1. Preparation before installation of centrifugal blower
(1) Before installing the equipment, be sure to pay attention to the corresponding position of the pneumatic conveying pipeline, and do a good job of the foundation of the centrifugal fan according to the relevant dimensions. The foundation is often the most critical part of the correct installation of the equipment.
(2) After we lay the foundation, we need to conduct a more comprehensive inspection of this equipment. As for whether all parts of the equipment can be tightly connected, and whether the corresponding transmission system is flexible, etc., once found, adjust it immediately, and don’t be careless.
2. Installation steps of centrifugal blower
(1) During the installation process, all parts of the machine should be cleaned to ensure that no debris appears.
(2) When installing, the corresponding air outlet pipe cannot be placed on the centrifugal fan. When we need to connect, we should pay attention to the natural fit, and there can be no other force.
(3) When installing the manual crank, make sure that the corresponding equipment will not be collided or too tight. Immediately after the discovery, the machine cannot be allowed to operate in the fault.
(4) Trial operation of such equipment is also very important as part of the installation process. We need to ensure that the equipment must operate in the pipe network, and there needs to be a regulating valve in the pipe network. When starting the machine, the valve needs to be closed, and when the machine is running normally, the valve can be gradually enlarged.
(5) Pay attention to the sound when the centrifugal blower is in trial operation, and be sure to control the amount of material when conveying materials. There must be no overloading of the motor. When there is an abnormal sound, it needs to be stopped immediately.
(6) is to check the operating environment of the equipment to avoid some flammable and explosive items appearing in the space where the machine is running. These are security risks.
When we install related equipment, we must follow the above order or the instructions provided by related manufacturers. For the device itself, if the installation order is incorrect or some details are not in place, there may be problems, and there will be some impact on the use of the device in the future. This is what we need to pay attention to.
