Water Sealed Vacuum Pump Creates Continuous Movement
Doubling as both a vacuum pump and a gas compressor, water sealed vacuum pumps are versatile. Water is used as a source of energy in order to compress the gas. A vacuum is created as water is pumped through a cylinder-shaped rotor. As the pump spins as a result of the vacuum, the process of gas compression begins.
The main function of a water sealed vacuum pump, also commonly referred to as a liquid ring vacuum pump, is to create a vacuum of continuous movement. The water is forced through one end of the pump. The seal that is created separates pressurized gas from liquid until it escapes out of the pump. The liquid seal that is created is there to maintain the vacuum’s negative pressure. This vacuum attempts to remove all atmosphere (or as much atmosphere as possible) from an enclosure. It is impossible to create a complete vacuum, a space in which no atmosphere is present.
The main advantage of the most commonly used, as well as the most preferred vacuum in industry is that its simple design manages combustible gases through the process of isothermal compression. This is done safely, making it advantageous. The biggest disadvantage of its simplistic design is its absorption of a lot of power when in use.
The water sealed vacuum pump was first patented to Lewis H. Nash in 1941. They were first manufactured by Nash Engineering Company. In today’s world, water sealed vacuum pumps are normally actuated and powered by an induction motor. In addition to water, an oil or other solvent may be used when creating a vacuum pump.
Water sealed vacuum pumps are extremely reliable, that is why they are so popular and so widely used. They are used for vacuum forming molded paper pulp products such as egg cartons, soil remediation, petroleum refining, vacuum distillation and in vapor recovery systems.
