Overview

The working performance of a two-stage rotary vane vacuum pump consists of two parts: a high-pressure stage and a low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment, and during operation, a large amount of gas inside the container is sucked in and discharged.

Product Details

　　Double stage rotary vane vacuum pumpInstallation method:

1. After unpacking, carefully remove the rotary vane vacuum pump body, spare accessories, and instructions, and keep them safe for future use. Remove the filling material and clean the surface dust and dirt of the pump. Count the quantity according to the packing list.

2. The rotary vane vacuum pump is installed in an indoor environment that is clean, well ventilated, and has sufficient light to meet the requirements of Article 4. According to usage, the pump should be installed in a spacious area for easy operation and maintenance. The external dimensions of the rotary vane vacuum pump are shown in. It can be placed on a solid and flat ground without the need for a special foundation. If it needs to be fixed, additional screws can be added to secure it firmly to the foundation. The size of the anchor screws is shown in. When using rotary vane vacuum pumps close to precision instruments, consideration should be given to adding shock-absorbing devices.

3. The container to be pumped should be connected to the rotary vane vacuum pump using a vacuum hose or flange. If a flange is used for connection, there should be a rubber ring groove on the flange, with the form and size shown in the above figure. The diameter of the pipe connecting the container to be pumped should not be smaller than the diameter of the pump inlet. The pipe should be short and the joints should be few, otherwise it will affect the pumping speed. The air leakage of the pipeline and joints should be small. The amount of gas in the container being pumped should be adapted to the pumping speed of the pump. It is recommended to install a vacuum valve between the pump and the container being pumped to control the gas flow rate. For the pump, it is recommended to install a vent valve (or solenoid valve) to release air during parking, which can prevent oil return and make it easy to start.

4. Connect the power supply according to the voltage and wiring method shown on the motor label, and it is recommended to use a safety device to prevent overload. Determine the direction of rotation of the motor, which should be in the direction of the arrow on the rotary vane vacuum pump. Remove the exhaust plug and install the exhaust hood, or remove the sleeve from the exhaust nozzle. The rotary vane vacuum pump requires the cooler to be connected to a water source.

5. If it is necessary to use a rotary vane vacuum pump to remove toxic and corrosive gases that corrode black metals, gases that cause chemical changes in vacuum oil, and gases that exceed room temperature and have dust, relevant devices such as neutralization, cooling, and filtration should be installed on the intake pipe to cooperate with the use, otherwise it will affect the performance and service life of the rotary vane vacuum pump. When extracting harmful gases to the human body, corresponding pipelines should be installed to direct the exhaust gas outdoors away from the work area for treatment.

Note: Be careful during installation to prevent iron filings, dirt, dust, etc. from falling into the rotary vane vacuum pump.

　　Double stage rotary vane vacuum pumpAs a dual stage structure, its working performance consists of two parts: a high-pressure stage and a low-pressure stage. Its suction port is connected to a vacuum container or vacuum equipment, and during operation, a large amount of gas inside the container will be sucked in and discharged. When the equipment obtains vacuum, the high-pressure stage exhaust valve plate will be closed, and the gas sucked in by the high-pressure stage will be transferred to the second stage and sucked in and discharged through the second stage, so that the vacuum equipment can obtain a certain vacuum. The technical parameters of this pump are 6 × 10-2pa. Depending on the user's usage, a vacuum booster pump can be equipped. This pump can be used as the front stage pump. Due to the enhanced pumping force of the booster pump, the front stage pump can continuously extract, allowing your equipment to obtain higher vacuum. This pump is suitable for use in metallurgy, chemical industry, electric light source vacuum, vacuum coating, food packaging, medicine, vacuum forming, electronics, drying and other fields.
