Industrial gas furnace medium pressure fan for air supply and combustion assistance, through pump blower Due to the frictionless operation of the impeller within the body, no lubrication is required, resulting in the exhaust gas being oil-free. It is an ideal pneumatic conveying gas source for industries such as chemical and food. Using aluminum alloy material to significantly reduce weight and achieve the goal of lightweighting; When in use, the flow rate changes very little with changes in pressure. Special blade design, low noise, long lifespan, suitable for pressure and air flow. In terms of material selection, the rotor, casing, and gear ring have sufficient mechanical strength. Safe operation and long service life are major features of blower products.

Toupu medium pressure fanInstallation precautions;

A、 Installation matters for medium pressure turbine:
The medium pressure through pump fan can be installed at any time in the place of use to supply compressed air or for evacuation. And it can be installed in any horizontal or vertical direction
1. Flat washers and spring washers must be used to tighten screws;
2. Can use rubber buffer to withstand the weight of medium pressure turbine fans, especially high-power medium pressure turbine fans;
3. For certain occasions where noise is required, a silencer can be installed to reduce noise (usually around 5dB), and the silencer should be installed at the end of the inlet or outlet duct;
4. For certain situations where high noise requirements are needed, a layer of soundproofing foam can be added based on the machine's own conditions to meet the on-site noise requirements. For specific information, please consult the manufacturer of medium pressure turbine fans or a professional noise control company;
5. When using sound-absorbing foam, pay attention to the distance between the fan and the box, the ventilation and heat dissipation of the fan, and the use of rubber buffer to bear the weight of the medium pressure fan. For specific details, please consult the manufacturer of the medium pressure ducted fan;
6. The inlet and outlet pipes of the medium pressure ducted fan should be connected using hoses to isolate vibration
7. Apply the roller 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.
9. The filter screens and mufflers 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.
10. The external connection of the inlet and outlet must be made using flexible hoses (such as rubber hoses, plastic spring hoses)

Medium pressure blowerHow to operate:

1、 Prepare
1. Check whether the mechanical and electrical parts are intact. 2. Operate the air brake arm to close the air brakes of two fans.
2、 Start up and operation
1. Close the power switch and activate the explosion-proof switch start button.
2. After starting the operation, check the operation of the fan and make records.
When a malfunction occurs during the operation of the ventilation fan, the power switch should be quickly disconnected, the dispatch room should be promptly reported, and the backup main ventilation fan should be immediately prepared to start. The conversion of the backup main ventilation fan must be completed within 10 minutes.
Before starting the backup ventilation fan, close the air damper, operate the pressure reduction start button, and open the working fan air damper after it runs normally.
三、停止
Under normal circumstances, the compensator stop button can be operated to stop the machine.

2. After receiving the shutdown notice from the technical director of the factory, the reason and duration of the shutdown, as well as the name of the notifier, should be asked and recorded.
3. In case of normal or unexpected shutdown, it is necessary to report to the dispatch room in a quick manner without delay. If the main ventilation fan stops running and ventilation cannot be restored in a timely manner (the conversion is not completed within 10 minutes), the underground power supply must be cut off and the explosion-proof door must be quickly opened to form natural ventilation.
4. Without the approval of the technical leader, the operation of the fan shall not be stopped.

Installation environment for medium pressure turbine:

1. Installation location: It must be installed indoors in a place that is not affected by wind and rain
2. Environmental temperature: below 40 ℃
3. Relative humidity: below 80%
4. Air quality: If there are corrosive or flammable gases such as acids and alkalis in the air, they should not be transported by medium pressure ventilation fans to avoid danger
5. Dust protection: Avoid using in places with large amounts of dust, powder, or fibers. If it is necessary to use in such places, please install a filter and regularly clean the dust attached to the filter screen and inside the medium pressure fan
6. Ventilation and heat dissipation: Please choose to use it in a well ventilated place and not in a sealed room or box
7. Placement space: For the convenience of column maintenance or repair, please avoid installing in overly narrow locations
8. Avoid vibration: Please install in a vibration free location; If the vibration in the venue is unavoidable, anti vibration measures must be installed to prevent the medium pressure turbine from being damaged by external vibrations.

Industrial gas furnace medium pressure fan for air supply and combustion assistance, through pump blowerPerformance parameters:

Among the performance parameters of medium pressure fans, the most important ones are gas flow rate, pressure, conveying power, efficiency, and impeller speed, which must be paid attention to during the selection process. The gas flow parameters of a medium pressure fan represent the volume of gas that the fan can process per unit time, while the pressure of a medium pressure fan refers to the internal gas pressure value during its operation.

The efficiency of a medium pressure fan refers to the ratio between the shaft power of the fan and the actual effective power of the processed gas. The total pressure efficiency of centrifugal fans is about 90%, and in the future development of centrifugal fans, efficiency value will be one of the goals further pursued by researchers.

Installation method of medium pressure fan:

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.
