In The Automotive Industry, Hydraulic Vane Pumps Are Essential

The increasing global population has put a lot of pressure on the industrial sector. Industries such as manufacturing, agriculture, mining, and construction are forced to operate at speeds to meet the growing demand of a growing population. Therefore, stakeholders have seen the need to increase productivity while trying to balance the costs involved in increasing production. In line with this requirement, participants in these industries are innovating machines such as automatic and vane pumps that will increase energy production while consuming limited natural resources. So, how do these vane pumps work to increase the efficiency of cars and superchargers?

Vane pump mechanism


The rotary vane pump, or vane pump for short, works on the principle of positive displacement. The pump consists of the installed rotor, outlet, inlet valve and vanes installed in the pump casing. They all converge to the center under the action of spring force. The intake valve is a vacuum safety device. The pump uses an electromagnetic motor. According to the size of the rotor and cylinder, the device can reach a large volume per minute, and can quickly obtain a higher vacuum. The machine uses a special oil to run smoothly and obtain high vacuum and maximum vacuum.


The blades are fixed on a central drive shaft, which allows it to rotate in the chamber. The length of the blade is variable and slides in and out of the chamber to maintain contact with the casing of the chamber. The rotation of the blades creates chambers of different sizes. The fluid is forced to enter through the largest chamber, and then the blades retract as they continue to rotate, thereby reducing the size of the chamber. Then, the fluid is discharged through the discharge port through the smallest chamber. Every revolution in the chamber will discharge a constant volume of fluid.




The design of the system has various advantages in terms of boost efficiency. The pump can process low-viscosity fluids such as LPG, refined fuel, liquid carbon dioxide and refrigerant under high pressure, and can be idling for a short time, and can form a good high vacuum.


As mentioned earlier, the goal is to increase the energy produced while keeping it in balance with the amount of fuel consumed. Rotating blades can self-adjust to maintain internal clearance. This mechanism ensures that very low energy is wasted and generates more electrical energy with limited energy consumption levels. The result is an engine with greater power, greater power, reduced greenhouse gas emissions and higher output.


Relationship with supercharger


In a supercharger, the pressure or density of air increases when it is supplied to an internal combustion engine. This allows more oxygen to enter the engine, burning more fuel and increasing power. For positive displacement pumps (such as vane pumps), the amount of air delivered per revolution is fixed at almost all speeds, so the required power can be maintained.



In the automotive industry, vane pumps are essential. Pumps play an important role in braking systems, automatic transmissions, and brakes other than supercharging.
