Nowadays, technology has changed quite fast, so does the vacuum pump technology. Many new concepts have been emerging to cater to their needs to accomplish the particular needs of the pump and the industry. However, dry screw vacuum pump technology has been used in many applications for many years since it has come into existence. These include variable pitch screw chemical dry pumps. But, a properly designed pump ensures that it’s cost-effective, safe, and reliable. A dry screw vacuum pump doesn’t need oil or water to work as sealing or lubrication in the vacuum process. Further, this dry vacuum pump eliminates the generation of pollution and also a high maintenance cost. Principle Of Operation These vacuum pumps use two screw rotors that rotate in the opposite direction. That further blocked the medium between the screw chambers and cylinder chambers by forcing it to move in the gas discharge side. Moreover, the advanced screw design leads to lower energy consumption than the primary design. It also helps in reducing the heat emission. Vacuum Booster On the other hand, the vacuum booster contains a metal chamber containing a diaphragm and valve. A rod passes through the center of the chamber and finally connects to the cylinder’s piston from one side and through the pedal with the other. Test Required For Vacuum Booster The basic test required to check the performance of the vacuum booster is mentioned below.
Booster Function Test: The first thing to do is to check the pedal and vacuum booster while driving your vehicle. You can do this through a simple step, just turn off the engine and apply the brake pedal with minimum pressure. Booster Vacuum Supply Test: By turning off the engine, press the brake pedal until it depletes the booster reserve. Then using a cone-shaped adapter, disconnect both hose and booster and connect to the vacuum gauge. Again start the engine and check the functioning of the vacuum gauge. In short, while checking the booster’s performance, you should first turn down the engine to get better access to your vehicle engine. Further, remember that the booster is used when high performance is required while the screw pump is used at moderate performance.
