A digital vacuum regulator is commonly use to control mechanical equipment’s inlet and outlet pressures. A prominent application for digital vacuum controllers is in the drying industry, where heavy machinery requires digital tools to handle stress.
What is a Vacuum Regulator?
A vacuum regulator is a device used to maintain the require vacuum pressure. There are several types of digital vacuum regulator. But the mechanical vacuum regulators mentioned here work according to the principle of balance of forces.
Two types of Vacuum Control
There are two main types of vacuum control devices: vacuum control devices and vacuum breakers. This page attempts to explain the different purposes of each type and how they work.
Type 1: Vacuum Regulators
Vacuum controllers like the Equilibar Vacuum (EVR) series work by regulating the amount of flow between the vacuum pump and the process to control the vacuum process. Now this type is often called a vacuum electronic vacuum regulator valve. The Equilibar EVR holds vacuum pressure stable across varying supply pressures. Traditional vacuum regulators are often sensitive to vacuum supply pressure It is a back pressure regulator. Because the digital vacuum regulator is at the inlet port. But the regulator is turned off to increase the absolute pressure of the system. (or reduce the degree of vacuum)
Type 2: Vacuum Breakers & Vacuum Relief Regulators
Another type of vacuum regulator allows ambient air to enter the vacuum system to control the pressure. This type of regulator is often call a vacuum regulator or digital vacuum regulator. These regulators are pressure-reducing because the pressure regulator is on the outlet port. The regulator opens to increase the absolute pressure of the process. (or reduce the degree of vacuum)
A negative pressure regulator typically uses a spring-loaded diaphragm with atmospheric pressure at the top and process vacuum pressure at the bottom. In this simplified example to the right, the spring pulls the diaphragm up to generate the negative reference pressure. When the process absolute pressure is too low (Vacuum too high), The piston will push the vacuum pressure regulator valve seat down. This allows more air to enter the process. When the absolute pressure of the operation increases (increases the vacuum pressure) to the setpoint, the piston goes back up to limit the airflow.
How Vacuum Regulators Work
The digital vacuum regulator controls and stabilizes pressure through inlet and outlet ports that allow pressurized air to enter or exit the system. But vacuum breakers and controllers work on a similar principle. But in case the controller does not let perspective into the production process. The vacuum switch will work depending on its use. This could mean spending more energy to clear the air passages and adjust the system pressure.
WHAT DOES A Precision Vacuum Regulator DO?
The vacuum control regulator controls the pressure within the system more efficiently than conventional individual valve seats. The spring-loaded diaphragm mechanism controls airflow from the pump or ambient air source for better internal pressure control. An adjustable vacuum controller ensures the operator is operating at the correct pressure. without frequent manual intervention.
