A centrifuge is a mechanical fluid that is driven by mechanical energy to increase gas pressure while delivering gas. Centrifuges are widely used for ventilation, dust removal and cooling of plants, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and air conditioning for boilers and industrial furnaces; cooling and ventilation equipment and household appliances in the air; Drying and selection; wind tunnel sources and hovercraft and promotion. Let the telecom motor factory tell you about the history of the centrifuge.

In 1862, the British Gobert invented the centrifuge, the impeller and the shell are concentric, the shell is brick, the impeller adopts the rear straight blade, and the efficiency is only about 40%, which is mainly used for mine ventilation.

In 1880, a coal mine ventilation volute and a back-bend vane centrifugal fan were designed. The structure of the centrifuge is relatively complete. 1892 cross-flow fan developed in France;

1898, Ireland for the San Siro stadium before the departure of the centrifugal fan, and widely used in the country; in the nineteenth century, the explosion has been applied to mine ventilation and metallurgical industry axial fans, but the pressure is only 100 ~ 300 kPa, the efficiency is only 15 ~ 25% until the rapid development of the 1940s.

In 1935, Germany first adopted boiler pressure and ventilator axial flow fan; 1948, Danish-made axial flow fan blade adjustable dynamic operation; meridian acceleration fan, axial flow fan, diagonal flow fan and cross flow fan;

2002, China explosion-proof centrifuge.

Widely used in petrochemical, machinery and other fields, Lindong explosion-proof centrifugal fan has been successfully developed. The centrifuge is auxiliary for the production equipment of stone processing enterprises. It is mainly used for ventilation and dust removal devices. For example, stone cutting and cyclone and bag filter polishing processes use centrifugal fan to produce on-site dust treatment to ensure clean production environment and protect producers. Health.

Fan is a kind of high-energy-consuming equipment. In a large proportion of stone processing center fan power consumption resources, and the current energy shortage and high-yield and high-efficiency work surface application, energy saving has become a common concern of stone production enterprises, many enterprises Stone production is currently an important task in reducing fan power consumption. In order to reduce the fan power consumption in addition to improving the efficiency of the fan itself, it is most important to adjust the reasonable selection of the fan. Because of the stone production load, most of the fans adjust the flow according to the host load as the technology and time change.

At present, the energy-saving adjustment methods for wind turbine processing enterprises are relatively old. When the throttle is throttled, the flow of the fan is mainly adjusted by the regulating valve or the throttle baffle. When the throttle is over 50% at low load, the energy is wasted due to the existence of throttling loss. very serious. If the fan speed is adjusted, the throttling loss can be canceled and the fan can always work in the effective area, which saves a lot of energy. It can be said that adjusting the operating speed of the fan is an effective way to save energy. Reflects the new trends in the current building materials industry.
