Transparent medium pressure blowerStructure:
Rotor: composed of shaft, impeller, bearing, synchronous gear, coupling, shaft sleeve, etc.
Impeller: Adopting a gradually opening linear surface for high volume utilization.
Bearing: 3000 type double row radial spherical roller bearings are selected as the positioning end near the coupling end. 32000 type single row radial short cylindrical roller bearings are selected as the free end near the gear end to adapt to the axial displacement of the rotor during thermal expansion.
Synchronous gear: composed of a ring gear and a hub, making it easy to adjust the impeller clearance.
Body: Composed of a casing and left and right wall panels. The left and right wall panels, as well as the bearing seats and sealing parts installed inside the left and right wall panels, can be interchangeable.
Base: Both small and medium-sized fans are equipped with a common base, while large fans are only equipped with a fan base for easy installation and debugging.
Lubrication: The gears use immersion lubrication, and the bearings use splash lubrication. Good lubrication effect, safe and reliable.
Transmission mode: mainly through direct coupling of couplings. If performance specifications require it, the method of variable speed with triangular pulleys can also be chosen. Elastic couplings are selected for the coupling, which can alleviate impact and compensate for a small amount of axis deviation. Large flow fans can also be driven by steam turbines or other means, in addition to electric motors

Usage and maintenance:

1. The fan should be placed in a relatively stable place, and the surrounding environment should be clean, dry, and well ventilated.

2. The rotation direction of the fan impeller must be in the direction indicated by the arrow on the fan casing.

3. When the fan is working, it should be avoided that the inlet and outlet of the fan are sealed to prevent excessive heat generated by the air pump and damage to the air pump caused by motor overcurrent.

4. Except for the two bearings of the motor rotor, there is no direct contact friction in other parts of the fan. The installation method of bearings for this air pump is mainly divided into two categories. The bearing at the end of the class air pump is installed in the pump body between the motor base and the impeller, and this type of air pump does not need to be lubricated normally. The bearings on the second type of air pump end are installed in the middle of the pump cover, and the bearings on this type of air pump end should be regularly lubricated with grease (7018 high-speed grease). Once a month, for air pumps that work continuously in three shifts, the refueling frequency should be increased. The maintenance and upkeep of the bearings on the motor and fan end of this type of air pump are classified according to the type of air pump.

5. The filter screens and silencers at both ends of the inlet and outlet should be cleaned in a timely manner according to the situation to avoid blockage and affect use.

6. The external connection of the inlet and outlet must be made using flexible hoses (such as rubber hoses or plastic spring hoses).

7. Bearing replacement: Bearing replacement must be carried out by personnel familiar with repair work. First loosen the screws on the pump cover, and then disassemble the parts one by one according to the order shown in the diagram. The disassembled parts should be cleaned, and then assembled in reverse order. When disassembling, do not forcefully pry the impeller, use a roller to remove it, and do not miss the adjusting gasket to avoid affecting the clearance that has been adjusted before leaving the factory.

8. It is strictly prohibited for solids, liquids, and corrosive gases to enter the pump body.

Installation method of aluminum medium pressure blower:

1. Use screws to firmly fix it to a horizontal and rigid foundation or base. The basic weight is generally about three times that of the air supply fan as the standard. If the base is uneven, the air supply machine may deform when the bolts are tightened, and special attention should be paid - please install shock absorbers to reduce noise.
2. The air supply fan is usually designed with the shaft in a horizontal state. When the suction port is used in an upward or downward direction, the weight of the impeller and sub shaft is added to the bearing on one side, increasing the load and reducing the bearing life.
When the ventilation duct is not connected to the suction port, please install wire mesh to prevent the inhalation of dangerous or foreign objects.
4. The fully closed external fan cover and the open motor should be at least 20mm away from the wall.

Transparent medium pressure blowerWidely used, including suction, feeding, air suction, air supply, and exhaust, in industrial and agricultural equipment; The medium pressure fan is specifically applied in packaging machinery such as fully automatic gluing and gluing machines, fully automatic box pasting machines, and pressure conveyors in cardboard packaging equipment; The turbo type medium pressure fan is driven by a gear reduction motor; The upper and lower wide rail belts have good paper pressing effect; The roller pressure adjustment adopts a weight type hammer structure, which is simple and convenient; Variable frequency speed adjustment ensures good paper adhesion and smooth drying.
