TB medium pressure transparent blower with strong dust suction for powder particle conveyingWorking principle:
When the impeller rotates, the wind vane pushes the gas forward and outward due to the centrifugal forceexerciseThus forming a series of spiral movements. The air between the impeller blades accelerates and rotates in a spiral shape, squeezing the gas outside the pump body into the side groove (sucked in through the suction port). When it enters the side channel, the gas is compressed and then returns to accelerate and rotate between the impeller blades again. When air passes through the impeller and side groove along a spiral trajectory, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, further increasing the pressure of the gas passing through the side channel. When the air reaches the connection point between the side groove and the discharge flange (the side channel narrows at the outlet), the gas is squeezed out of the blades and discharged from the pump body through the outlet muffler.

Explosion proof medium voltage fanStructural Description
2.1 The explosion-proof structure of the electric fan has Ex dI, Ex dIIAT4, and Ex dIIBT4.
2.2 The protection level of the main body shell of the electric fan is IP55.
The cooling method of the electric fan is IC411.
2.4 The insulation level of the electric fan is F level, and the stator winding has a large temperature rise margin and a long service life.
The 2.5 electric fan has a cylindrical shaft extension, which is driven by a coupling or gear.
2.6 The stator winding of the electric fan adopts high-strength enameled round copper wire, which is vacuum pressurized and immersed in paint to form a complete whole. The winding and insulation have good electrical, mechanical, moisture-proof performance and thermal stability.
2.7 The rotor of the electric fan adopts a cast aluminum structure, and the rotor has undergone dynamic balance verification. The motor runs smoothly, with low vibration and noise.
2.8 The stator and rotor blades of the electric fan are made of high-quality electrical silicon steel sheets with high magnetic conductivity and low loss, resulting in low motor loss and high efficiency.
2.9 The bearings for the electric fan are selected as low vibration and low-noise bearings for the motor. Double sided sealed bearings are used for machine seat sizes 160 and below, and waveform spring washers are installed at the shaft extension end to provide moderate pressure against the bearings and effectively suppress the vibration and noise generated during motor operation. For machine seat sizes 180 and above, inner and outer cover structures are used, and retaining rings are used for axial fixation at the bearing locations to effectively prevent axial movement of the motor rotor.
For the safe and reliable operation of electric motors, the bearing structure of motors with a base size of 180 and above is equipped with an oil injection device. For motors with a base size of 250 and above, a position for bearing temperature monitoring sensing elements is reserved.
2.10 Motor fan and fan cover: Motors with a base size of 280 and below use anti-static plastic fans, which have low rotational inertia and low loss. Motors with a base size of 315 and above use cast aluminum or steel plate welded fans, which are lightweight and strong. The entire series of fans are connected to the shaft with critical connections, ensuring reliable operation. The wind cover is made of steel plate structure, which provides a large ventilation area while preventing the intrusion of foreign objects of a certain size, ensuring smooth air flow.

Explosion proof and heat-insulating medium pressure fanInstallation and usage requirements:

1. Understand the specifications, form, inlet and outlet positions, and corresponding installation dimensions of the fan, as well as the power requirements for the motor used
2. Before installation, carefully check whether the fan blades and casing have been damaged or deformed due to transportation, and check whether the bolts are firm. Otherwise, they should be repaired before installation and use
3. The smoke exhaust outlet and smoke exhaust fan should be equipped with interlocking devices. When any smoke exhaust outlet is opened, the smoke exhaust fan can automatically start
Before starting the fan, first check the smoke exhaust fan and whether there are any objects inside the fan and pipeline that hinder rotation; Check if the electrical circuit is intact
5. After installation, regularly inspect all components of the fan and check if the bearing lubrication is sufficient to ensure that the fan can start and operate normally at any time
6. The rotation direction of the impeller must match the arrow roof fan head mark on the air duct

TB medium pressure transparent blower with strong dust suction for powder particle conveyingMaintenance needs:
1) When setting up the fan, it should avoid environments with high dust, corrosive gases, high humidity, direct sunlight, and wind and rain. The ground around the fan should be kept clean. The fan is equipped with an electric motor that has high requirements for the surrounding environment. Often, its performance may be reduced due to the aforementioned reasons, so special attention should be paid.
2) When the fan is installed indoors The structure of the house should be spacious and have doors that are wide and high enough to facilitate the movement and transportation of fans.
3) There must be sufficient space around the fan for operation Personnel can walk freely and meet the needs of daily maintenance and upkeep.
4) The installation location of large fans Consider leaving space for the placement of components such as the casing, rotor, intake box, and regulating door, as well as for assembly, disassembly, maintenance, and other operations. The fan adopts belt drive, and the space for motor alignment and pulley replacement also needs to be considered.
5) When determining the layout of the fan Not only should the installation space of the fan itself be considered, but also the layout space for inlet and outlet pipelines, valves, wiring of the prime mover, oil supply devices, cooling devices, and connecting pipelines for oil and water should be reserved
6) When setting up multiple wind turbines at the same location The mutual spacing and layout between fans should be fully considered to avoid mutual influence during fan operation
7) For large and heavy fans Should be equipped with lifting devices such as cranes and electric hoists; Small and medium-sized fans are equipped with general lifting devices according to their purposes, such as frequent replacement of impellers.

Explosion proof blowerSuitable for places where explosive gas mixtures are present:
