Application Of Vane Pumps On Aircraft
2020年4月20日The vane pump is usually used as a high-pressure hydraulic pump for automobiles, which can perform braking, boosting, air conditioning and automatic transmission. Although there are also mid-range pressure pumps for soft drink dispensers and espresso machines.
In other words, these pumps have also become an important part of air travel. Without them, today’s modern aircraft will not be able to operate.
How Vane Pumps improve air travel
The vane pump is a rotary pump designed to handle medium and low viscosity liquids. This is a vacuum pump. Although the back pressure has changed (this is called positive displacement), it still sends liquid through its housing at a constant speed at a constant speed.
It is called "constant flow machine", it can obtain good results when dealing with gasoline, fuel oil, alcohol ammonia and liquefied petroleum gas, and it is most commonly used in the automotive industry.
These pumps can self-compensate for tearing and wear, and many different functions depend on it. It has become a key equipment for braking, power steering, automatic transmission and supercharging.
Although it is most commonly used in automobiles, many other vehicles also rely on this pump, including aircraft. There are many different configurations of vane pumps, they are easy to maintain and have good suction.
How the vane pump works
A key thing to note when understanding the working principle of a vane pump is that it will produce a fluid movement-it will not generate pressure. The mechanical action creates a vacuum, which forces the liquid to flow from the reservoir to the pump, and then moves it into the hydraulic system.
As mentioned above, this is done with positive displacement. Although there are many different configurations of vane pumps, the working principle is basically the same.
Each pump is equipped with a circular rotor that rotates in a large circular cavity (called a cam). The centers of these two circles are offset, causing eccentricity (which means they do not share the same center).
The blades are allowed to slide in and out of the rotor, and sealed at all edges to form a blade chamber to complete the pumping work. On the intake side of the pump, the volume of the vane cavity is increasing. These increased-volume blade cavities are filled with fluid driven by the inlet pressure.
The inlet pressure is actually the pressure from the pumping system, usually just atmospheric pressure. On the discharge side of the pump, the volume of the vane cavity decreases, forcing fluid out of the pump. The function of the blade is to expel the same volume of fluid with each revolution.
Unlike other pumps, vane pumps allow fluid to flow quickly through the system. This helps increase the pressure of the fluid. If the fluid is thin, the transmission speed will increase and the pressure will increase significantly.
Application of vane pump on aircraft
Almost all modern aircraft use hydraulic power components. Since they are engine-driven, air-driven and use electric pumps, they cannot run without them.
In smaller, lighter aircraft, the vane pump may only be used to activate the wheel brakes, although in large aircraft such as the Airbus A380-800, the use of these systems is more important (not the brake itself is not important !)
Usually depends on the size of the aircraft, multiple hydraulic systems will work together, and are critical for braking, front wheel steering, extended landing gear, flaps and slats, operating cargo door / loading ramps, and pitch control of the aircraft, etc. Important propeller.
They are also used to control wipers. You may not think that these require a lot of power or pressure, but when the aircraft we are talking about usually travels at a speed of 930 km / h, you will need a lot of power because of the severe weather that blows down from the air at close range .
The advantage of using vane pumps for aerospace for all these purposes is that it can handle thin liquids at higher pressures and compensate for wear through the extension of the vanes.
In this way, you can-the importance of vane pumps on aircraft-a kind of mechanical engineering, although you may never have heard of it before, it can ensure your safety in the air and can be delivered to you in one stop you.
