The universal crusher is used in places with flammable and explosive gases to avoid accidents caused by some flammable and explosive substances. The universal crusher is widely used for ventilation, dust removal, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings. Ventilation and pulverizer for boilers and industrial furnaces; Cooling and ventilation in air conditioning equipment and household appliances; Drying and grain selection; The wind source in the wind tunnel and the inflation and propulsion of the hovercraft.
But when the transported gas contains flammable and explosive substances, dust, smoke, or volatile substances, the motor short circuit, circuit failure, sparks, etc. generated by the friction between the crusher impeller and its components during the operation of the crusher can ignite the transported substance or gas, causing serious accidents. Therefore, the selection of a universal crusher is particularly important. Next, Bian Xiao will introduce some precautions when choosing a universal crusher.
How to choose a universal crusher?
The selection of crusher model should be based on the actual situation of the factory, and try to choose a crusher model that matches the original window size. The crusher should be kept at a certain distance from the wet curtain (installed on both sides of the factory gable as much as possible) to achieve good ventilation effect. The exhaust side should be as far away from nearby buildings as possible to avoid affecting nearby residents.
Crusher air pressure: refers to the resistance that needs to be overcome during the process of conveying such a large amount of air, and refers to the pressure rise. However, the selection of fans in China is generally full pressure, while fans in foreign countries are generally pushed up. External residual pressure=total pressure of the crusher - resistance of each processing section of the air cabinet. The resistance of the return air duct is generally calculated at 7-8Pa/m, and the 90 degree elbow is calculated at 10Pa/piece.
From the perspective of a fan, a universal pulverizer is no different. It is all driven by an electric motor to rotate the fan blades and generate wind power. The different functions of the pulverizer are determined by the location of its installation. The former is located at the rear end of the boiler, blowing air towards the flue outside the boiler, generating negative pressure on the furnace and guiding the flue gas, hence it is called a pulverizer; On the contrary, the latter is located at the front end of the boiler, blowing air into the boiler, hence it is called a drum crusher.
