Product Description

Product Description

2XZ-4 rotary vane vacuum pump is double stage high speed oil sealed rotary vane vacuum pump (in the following called “the pump” for short).

Its pumping principle is as same as that of 2X type pump .Rotors are eccentrically mounted within the cylindrical housing of the stators and vanes are fitted freely inside the respective slots of the rotor. When the rotor rotates at high speed, vanes in the rotor slot are urged outwards by centrifugal force as well as by spring force so as to keep close contact at their tips with the stator wall throughout rotation.

Thus the inlet port and outlet port on the stator are separated by them. The volume of the space leading to the inlet port expands progressively and periodically with gas filling the space through inlet pipe, meanwhile the volume of the space leading to the outlet port diminishes progressively and periodically to compress the gas previously sucked .By means of gas pressure and oil pressure exhaust valve on the outlet port is opened to expel gas out of the pump through the valve, then vacuum is obtained at the intake side of the pump .

Double stage pump is the arrangement of 2 CHINAMFG pumps in series .When the intake pressure is higher, both stages of the pump may exhaust simultaneously ,while at lower suction pressure gas is first expelled out from first stage to second stage ,then from second stage exhausts to the open air .

Product Application

1. The pump is 1 of the basic equipment to exhaust a sealed vessel. It can be used either independently as main and can also be served as for pump for booster pump diffusion pump and molecular pump or as holding pump for a vacuum system and as a pre-pumping for different kinds of the pumps. So that is can be applied in electro-vacuum industries, vacuum flask manufacturing, vacuum welding and as an accessory to those fine gauges or CHINAMFG where vacuum is required .It is more suitable for laboratory use because of its small size ,less weight and quiet operation.

2.The pump is allowed to work continuously for many hours at a stretch under atmospheric temperature of 5ºC-40ºC and intake pressure below 1230pa.While the pumped gas containing moisture of a relative humidity of more than 90% gas-ballast valve should be open.

3. Whit the inlet port widely opened to atmosphere the pump is not allowed to work more than 1 minute.

4.The pump is not suitable for pumping over-oxidized, poison, explosive and corrosive gas as well as gases which react chemically with the pump oil contain particles of dust.

What Are the Main Components of a Rotary Vane Pump?

A rotary vane pump consists of several key components that work together to create a pumping action. Here’s a detailed explanation of the main components:

– Rotor: The rotor is the central rotating element of the rotary vane pump. It is typically made of a durable material such as stainless steel or cast iron. The rotor is connected to a drive mechanism, such as an electric motor, which provides the rotational power.

– Vanes: The vanes are sliding elements that are inserted into radial slots in the rotor. They can be made of various materials, including carbon, graphite, or synthetic materials. The number of vanes in a rotary vane pump can vary, but typically there are multiple vanes evenly spaced around the rotor. The vanes are crucial for creating a seal against the stator walls and for generating the pumping action.

– Stator: The stator is the stationary part of the rotary vane pump. It forms the pump chamber and provides the housing for the rotor and vanes. The stator is typically cylindrical in shape with an eccentric bore that accommodates the rotor. It is commonly made of materials such as cast iron or stainless steel to ensure durability and resistance to wear.

– Inlet and Outlet Ports: The rotary vane pump has separate inlet and outlet ports. The inlet port allows the entry of gas or fluid into the pump, while the outlet port facilitates the discharge of the pumped medium. These ports are strategically positioned on the pump housing to enable the flow of the medium in and out of the pump.

– Seals: Seals are essential components of a rotary vane pump as they prevent leakage and maintain the integrity of the pumping system. The primary seal is formed between the vanes and the stator walls, ensuring that gas or fluid is contained within the pump chamber during the pumping process. Additional seals may be present at the inlet and outlet ports to prevent any leakage at these points.

– Lubrication System: Rotary vane pumps often require lubrication to minimize friction and wear between the rotating components. Lubrication is typically achieved by introducing a small amount of oil or lubricant into the pump chamber. The lubricant helps reduce friction between the vanes and the stator walls, ensuring smooth operation and extending the lifespan of the pump.

– Exhaust Valve: Some rotary vane pumps feature an exhaust valve, also known as an anti-suckback valve. This valve is located at the outlet port and prevents the reverse flow of gas or fluid back into the pump when it is not in operation. The exhaust valve helps maintain the integrity of the vacuum or pressure created by the pump.

– Drive Mechanism: The drive mechanism provides the rotational power to the rotor, enabling the pumping action. In most cases, an electric motor is used as the drive mechanism, although other power sources such as hydraulic or pneumatic systems can also be employed.

– Base or Mounting Plate: The base or mounting plate provides a stable platform for the rotary vane pump. It is typically made of sturdy materials such as cast iron or steel and is designed to support the weight of the pump and provide a secure attachment point for installation.

– Control and Monitoring Devices (Optional): Depending on the specific application, rotary vane pumps may be equipped with control and monitoring devices. These can include pressure sensors, flow meters, temperature sensors, and control panels that allow for the regulation and monitoring of pump performance.

– Safety Features (Optional): Some rotary vane pumps may include safety features such as overpressure relief valves or automatic shutdown mechanisms to prevent damage to the pump or the system in case of abnormal operating conditions.

In summary, the main components of a rotary vane pump include the rotor, vanes, stator, inlet and outlet ports, seals, lubrication system, exhaust valve, drive mechanism, base or mounting plate, as well as optional control and monitoring devices and safety features. These components work together to create a continuous pumping action and ensure the efficient operation of the rotary vane pump.
