SINGLE STAGE ROTARY HIGH VACUUM PUMP
single stage rotary high vacuum pump
A single stage rotary high vacuum pump is a type of vacuum pump that is designed to remove gas molecules from a sealed chamber or system to create a high vacuum environment.
JD VACUUM SERVICE
The pump operates using a rotating mechanism consisting of an eccentrically mounted rotor, vanes, and a stator. The rotor rotates inside the stator, and as it does, the vanes slide in and out of the rotor slots. This action creates expanding and contracting chambers that draw gas molecules into the pump and then expel them through an exhaust port.
Unlike multi-stage pumps, single-stage pumps have a single set of vanes and only one rotor, making them simpler in design and operation. However, they are typically limited to achieving vacuum levels in the range of 0.5 to 0.005 mm/hg.
Single stage rotary high vacuum pumps are commonly used in applications such as analytical instruments, research laboratories, and in the semiconductor and pharmaceutical industries, where a clean and high vacuum environment is required. They are also used in industrial processes where high vacuum levels are needed for manufacturing or processing.
single stage rotary high vacuum pump Specifications
The specifications of a single stage rotary high vacuum pump can vary depending on the specific make and model of the pump. However, some common specifications include:
Pumping speed: This refers to the amount of gas that the pump can remove from a system per unit of time and is typically measured in liters per second (L/s) or cubic feet per minute (CFM).
Ultimate vacuum: This is the lowest pressure that the pump can achieve and is typically measured in Torr or Pascal (Pa).
Power consumption: This is the amount of power that the pump requires to operate and is typically measured in watts (W).
Noise level: This refers to the level of noise that the pump generates during operation and is typically measured in decibels (dB).
Inlet/outlet size: This refers to the diameter of the inlet and outlet ports on the pump and is typically measured in inches (in) or millimeters (mm).
Cooling method: This refers to how the pump is cooled during operation and can include air-cooled, water-cooled, or oil-cooled methods.
Weight and dimensions: These are important considerations for the overall size and portability of the pump, especially if it needs to be transported or integrated into a larger system.
It’s important to note that the specific specifications of a single stage rotary high vacuum pump will depend on the intended application, and it’s recommended to consult with a manufacturer or supplier to determine the most appropriate pump for a given use case.
