Usage, model and price of explosion-proof three blade roots blower
Literally, it is easy to understand that explosion-proof roots blower is to prevent explosion and other accidents, which requires strict sealing. The manufacturing industry is also relatively complex, and the use of raw materials is higher than that of ordinary three blade roots blower.
1、 Use of explosion-proof three blade roots blower
It is widely used in electric power, chemical industry, steel smelting, cement, pneumatic transmission, sewage treatment and other sectors and industries, and the transmission medium is clean air.
The following is the actual picture of explosion-proof three blade roots blower factory
II Features of explosion-proof three blade roots blower:
1. Explosion proof Roots blower has high volumetric efficiency, large air supply, stable operation, reliable use and relatively stable working characteristics.
2. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan is permanent and can operate continuously for a long time.
3. For forced gas transmission, the flow changes little with the pressure, the outlet pressure is determined by the back pressure, and the transmission gas is not polluted by oil.
4. The selection of bearings is reasonable, the service life of each bearing is even, and the fan oil seal is made of imported fluororubber material, which is high temperature resistant and wear-resistant, so the fan has a long service life and high reliability.
5. The fan has large volume utilization rate, high volume efficiency, simple and compact structure, and flexible installation mode. Easy to use and maintain.
6. Due to the adoption of the three blade rotor structure and the reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise. Pressure and temperature control to provide unit operation protection.
3： What are the model parameters of explosion-proof three blade roots blower
The model parameters of the explosion-proof three blade roots blower are basically the same as those of the ordinary roots blower, but the raw materials and process are different,
The following figure shows the model parameters of explosion-proof three blade roots blower: model
(xqs Roots blower) | Air volume range
（m ³/ min） | Power range
(kw) | Outlet diameter | Fan weight
（KG） | Pressure range | Voltage |
| Sr50T | 0.65-2.13 | 0.75-4 | DN50 | 87-119 | 9.8kp-58.8kp | 380V |
| Sr65T | 0.94-3.00 | 0.75-5.5 | DN65 | 98-145 |
| Sr80T | 2.34-5.22 | 2.2-7.5 | DN80 | 156-200 |
| Sr100T | 3.25-8.05 | 2.2-15 | DN100 | 190-297 |
| Sr125T | 5.35-11.7 | 3-18.5 | DN125 | 285-401 |
| Sr150T | 10.37-27.15 | 7.5-45 | DN150 | 471-706 |
| Sr175T | 19.65-38.67 | 11-75 | DN175 | 601-1090 |
| Sr200T | 27.65-57.14 | 15-90 | DN200 | 975-1490 |
4： Whether the price of explosion-proof roots blower is high:
Since the transmission medium of explosion-proof roots blower is special gas, such as biogas, gas, natural gas and other special gases, explosion-proof three blade roots blower is required to have explosion-proof characteristics. Therefore, when customizing Roots blower, the price factor is generally determined by raw materials and process. Therefore, this Roots blower needs to be customized, and explosion-proof mainly focuses on two aspects: anti-corrosion and sealing
First, raw materials
① Full set of stainless steel: This requires full set of stainless steel, and the casing, body and internal parts are all made of pure stainless steel. It can be imagined that the safety is very high, and the price is also very high.
② The packing seal is to coat a layer of stainless steel on the surface, which is about one centimeter in general, so it is safe and secure. It has many advantages in price and is also widely used.
The second is process:
① The sealing performance is mainly to seal both ends of the rotor bearing and the connection with the oil tank to prevent gas from reacting with the oil in the oil tank, and also to prevent leakage, because special gases such as gas, biogas and natural gas are flammable and explosive.
② Therefore, there is a big difference between the explosion-proof three blade roots blower and the ordinary type in the manufacturing process. The process is relatively complex, and the price will be much more expensive than the ordinary type roots blower.
Conclusion: The factors affecting the price of explosion-proof three blade roots blower are clear at a glance. Roots blower manufacturers will customize according to requirements, with different demands and prices.
