Where is the installation site of the high pressure fan of Shige?

1.The installation location of the high-pressure fan --- of the Lion Song fan must be installed indoors in a place where it is not disturbed by wind and rain.

2.The ambient temperature --- around 40.

3.The relative humidity --- less than 80%.

4.Air quality--- If the air contains acid, alkali and other corrosive or flammable gases, it should not be transported by Tianjin high-pressure fans to avoid danger.

5.Dust protection --- a large amount of dust, powder or fiber and other places should be avoided, such as necessary to use in such occasions, ** install filters, and regularly clean up the dust attached to the filter screen and Tianjin high-pressure fan.

6.Please choose --- use in a well-ventilated place, not in a closed room or closed box.

7.The storage space --- convenient for maintenance or repair, please avoid installing too small a place.

8.Avoid vibration--- please install in a vibration-free place;If the vibration of the site is unavoidable, anti-vibration measures must be installed to avoid damage to the high-pressure fan caused by external vibration.

Easy installation, high reliability, high compression ratio, low bearing operating temperature, no oil and no pollution, easy maintenance, appearance of the impeller edge of the Lion Song high-pressure fan with multiple blades, when the impeller rotates, due to centrifugal action, two blades.

The principle and structure of the Lion Song high-pressure fan:

The high-pressure fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas, which is a driven fluid machine.

Shige high-pressure fan is China's customary abbreviation of gas compression and gas transmission machinery, commonly referred to fans include fans, blowers, compressors and roots blowers, centrifugal fans, rotary fans, water ring fans, but do not include piston compressors and other positive displacement blowers and compressors. Gas compression and gas conveying machinery is a machine that converts rotating machinery into gas pressure energy and kinetic energy, and transports gas out.

The high-pressure fan is mainly composed of fan blades, shutters, window opening mechanism, motor, pulley, air inlet hood, inner frame, casing, safety net and other components. When the machine is turned on, the fan blade is driven by the motor to rotate, and the window opening mechanism is made to open the shutter and exhaust the air. The blinds close automatically when the machine is stopped.

I don't know what kind of high-pressure fan you want, whether it's a high-pressure blower, or a roots blower.

The inlet filter of the high-pressure fan is blocked;

The impeller wears out, and the gap increases too much;

Lion Song high-pressure fan belt is wide and slippery;

Large loss of inlet pressure;

The high-pressure fan duct of Lion Ge caused the ventilation leakage and the lead was shiny.

Performance characteristics of Shige blower:

The essence of the Shige blower is a variable flow constant pressure device. When the rotational speed is constant, the pressure-flow theory curve of the Lion ring blower should be a straight line. The actual characteristic curve is curved due to internal losses.

The pressure generated in the Lionsong ring blower is greatly affected by changes in inlet air temperature or density. For a given inlet volume, the pressure generated at the highest inlet temperature (the lowest air density) is the lowest. For a given pressure and flow profile, there is a power versus flow curve.

When the blower is running at a constant speed, the power required for a given flow rate increases as the inlet air temperature decreases.

When the pipe is sleeved into the air inlet and outlet, please keep the center consistent, and do not connect it under the condition that the slag is reluctant. Ducthoses can be easily connected and vibration-proof preachers can be easily connected and vibration-proof. Please do not add the weight of the pipe directly to the flange surface of the high-pressure fan to prevent deformation.

When the hot air is induced, please use flexible joints to avoid being affected by thermal expansion. Avoid sudden shrinkage, enlargement, bending, etc., which may make the fluid inefficient.

The built-in fan of the high-pressure blower is the main means of heat dissipation inside the box, which will ensure the normal operation of the control circuit. Therefore, if the fan is not functioning properly, it should be protected immediately.

Overheating protection of the inverter module heat dissipation wide row plate The inverter module is the main residual component of heat generation in the high-pressure blower, and it is also the most important and vulnerable component of the high-pressure fan. Therefore, each inverter is equipped with an overheat protection device on the heat dissipation plate.

Brake resistor overheat protection The nominal power of the brake resistor is selected for short runs. So, once the power is on for too long, it will overheat. At this time, it should be suspended and used again after cooling. Or choose a larger power resistor.

The inlet and outlet of the cooling air duct shall not be blocked, and the ambient temperature may also be higher than the allowable value of the high-pressure fan.

1. The inlet temperature of the conveying medium of the Shige fan is usually not greater than 40.

2. The content of particles in the medium shall not exceed 100mg m3, and the maximum size of particles shall not exceed half of the minimum working clearance.

3. The bearing temperature shall not be higher than 95 during operation, and the lubricating oil temperature shall not be higher than 65.

4. The use pressure shall not be higher than the boost range specified on the nameplate.

5. The gap between the impeller and the casing, the impeller and the side plate, and the impeller and the impeller of the Shige fan has been adjusted when leaving the factory, and the gap should be ensured when reassembled.

6. When the Shige fan is running, the oil level of the main oil tank and the auxiliary oil tank must be between the two red lines of the oil level gauge.

7. Check whether the inlet and outlet connection parts have forgotten the solid place, and whether the supporting parts of the piping are complete.

The petrochemical industry focuses on the localization of Shige high-pressure fan products with an annual output of 300,000 tons of synthetic ammonia and 300,000 tons of ethylene plants, and drives the development of large-scale ethylene deep processing, coal chemical and other petrochemical equipment supporting fan products.

Among the high-voltage fans of large-scale thermal power stations in Tianjin, the high-pressure fans supporting the 10,000-kilowatt power station are basically based in China, with a localization rate of more than 85%, and the product level has reached the international level of the late eighties and early nineties. In order to meet the needs of environmental protection, we actively develop flue gas desulfurization devices.

In terms of metallurgy, 4,000 cubic meters of blast furnace supporting Shige high-pressure fan, 450 square meters of sintering supporting fan, energy ** device and other products have a localization rate of 85%.
