Tsurumi Condenser Vacuum Pump Package（Model　ＶＭＡＦ）_Tsurumi Pump

Summary

The Tumi pump's VMF model is a two-stage liquid ring vacuum pump package, designed for simplicity and high efficiency. It operates by sucking and compressing gases, with a motor-driven pump and a separator tank that divides water and gas. The recirculation pump reuses separated water, while a heat exchanger cools it. The pump's innovative design allows for automatic switching between stages based on vacuum range, achieving high compression ratios through dual-stage compression. This ensures optimal performance across various vacuum levels.

Takeaways

• 🛠️ The Tumi pump's condenser vacuum pump, package model VMF, is a two-stage liquid ring vacuum pump package designed for simplicity and efficiency.
• 🌀 The basic structure of the vacuum pump includes a motor, vacuum pump, separator tank, seal water recirculation pump, and a heat exchanger.
• 💧 The vacuum pump sucks in and compresses gases, while the separator tank separates water and gas, which are then discharged from the pump.
• 🔁 The seal water recirculation pump plays a crucial role in recirculating the water that has been separated in the separator tank.
• 🌡️ The heat exchanger is responsible for cooling the seal water, ensuring the system operates at optimal temperatures.
• 🔧 The components are arranged in an optimum manner to achieve high efficiency in the vacuum pumping process.
• 🌀 The operation principle of the liquid ring vacuum pump involves an impeller rotating eccentrically to the casing, creating a crescent-shaped space that compresses and discharges the gas.
• 🔄 The model VMAF has an automatic switching mechanism that adjusts the compression stages based on the vacuum range.
• 📉 In the low vacuum range, gas is compressed by the first stage casing and discharged through a check valve in the bypass line, bypassing the second stage.
• 📈 In the high vacuum range, the check valve closes, and gas that has been partially compressed in the first stage enters the second stage for further compression.
• 🌐 The two-stage compression process allows for achieving a high vacuum and high compression ratio, with the gas eventually being discharged to the separator tank.

Q & A

What type of vacuum pump is the Tumi pump's condenser vacuum pump, package model VMF?

The Tumi pump's condenser vacuum pump, package model VMF, is a two-stage liquid ring vacuum pump package.

What is the basic function of the vacuum pump described in the script?

The vacuum pump sucks in and compresses gases, with the motor driving the pump to achieve this function.

What role does the separator tank play in the vacuum pump system?

The separator tank separates the water and gas that are discharged from the vacuum pump.

What is the purpose of the seal water recirculation pump in the system?

The seal water recirculation pump recirculates the water that has been separated in the separator tank.

How does the heat exchanger contribute to the efficiency of the vacuum pump system?

The heat exchanger cools the seal water, which is crucial for maintaining the system's high efficiency.

What is the significance of the optimum arrangement of components in the vacuum pump system?

The optimum arrangement of components allows for high efficiency in the operation of the vacuum pump system.

How does the gas flow from intake to compression and discharge in the vacuum pump?

The gas enters through the gas inlet nozzle, passes through the side cover and port plate, and then enters the first stage casing for compression and discharge.

What is the operation principle of the liquid ring vacuum pump as described in the script?

In the liquid ring vacuum pump, the impeller rotates eccentrically to the casing, forming a crescent-shaped space that compresses and discharges the gas by volume changes between the blades.

How does the model VMAF handle different vacuum ranges during operation?

Model VMAF automatically switches from first stage compression to second stage compression according to the vacuum range, optimizing the compression process.

What happens in the low vacuum range with the VMAF model?

In the low vacuum range, gas is compressed by only the first stage casing and discharged through the check valve in the bypass line, without compression in the second stage casing.

How is the gas processed in the high vacuum range in the VMAF model?

In the high vacuum range, the check valve closes automatically, and gas compressed to a certain degree in the first stage casing enters the second stage casing, where it is further compressed to atmospheric pressure before being discharged.

What is achieved through the two-stage compression process in the VMAF model?

A high vacuum and high compression ratio are achieved through the two-stage compression process in the VMAF model.
