Application scope and characteristics:
Greentech International (Xihu (West Lake) Dis.) Co., Ltd is the professional vacuum pump supplier. 2BE1 series water ring vacuum pumps and compressors are the products with high efficiency and economic power, which are manufactured by our company integrating with the advanced technology of the imported products from Germany.
These series products adopt CHINAMFG and single action structure and have many advantages, such as, compact structure, convenient maintenance, reliable running, high efficiency and economic power.
The main characteristics of 2BE1 series products:
All the bearings are the imported products with the brand name of CHINAMFG orNTN for ensuring the precise orientation and the high stability during the working of the pump.
The material of the impeller is QT400 nodular iron or stainless steel for ensuring the stability when the pump works under the rigorous condition and can extend the lifetime of the pump.
The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE1 series pumps.
The shaft bushing is made of stainless steel to improve the lifetime of the pump 5 times than the normal material.
The V-belt pulley (when the pump is driven by the belt) is used the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.
The coupling is used to drive the pump directly. The flexible part connecting the 2 half coupling is made of polyurethane that makes the pump more reliable.
The unique design to set the separator above the pump saves the space and decreases the noise efficiently.
All the parts are cast by the resin sands that make the pump surface very smooth. It is not necessary to cover the surface of the pumps with putty and gives out the heat efficiently.
The mechanical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.

How Do Vacuum Pumps Affect the Performance of Vacuum Chambers?
When it comes to the performance of vacuum chambers, vacuum pumps play a critical role. Here’s a detailed explanation:
Vacuum chambers are enclosed spaces designed to create and maintain a low-pressure environment. They are used in various industries and scientific applications, such as manufacturing, research, and material processing. Vacuum pumps are used to evacuate air and other gases from the chamber, creating a vacuum or low-pressure condition. The performance of vacuum chambers is directly influenced by the characteristics and operation of the vacuum pumps used.
Here are some key ways in which vacuum pumps affect the performance of vacuum chambers:
1. Achieving and Maintaining Vacuum Levels: The primary function of vacuum pumps is to create and maintain the desired vacuum level within the chamber. Vacuum pumps remove air and other gases, reducing the pressure inside the chamber. The efficiency and capacity of the vacuum pump determine how quickly the desired vacuum level is achieved and how well it is maintained. High-performance vacuum pumps can rapidly evacuate the chamber and maintain the desired vacuum level even when there are gas leaks or continuous gas production within the chamber.
2. Pumping Speed: The pumping speed of a vacuum pump refers to the volume of gas it can remove from the chamber per unit of time. The pumping speed affects the rate at which the chamber can be evacuated and the time required to achieve the desired vacuum level. A higher pumping speed allows for faster evacuation and shorter cycle times, improving the overall efficiency of the vacuum chamber.
3. Ultimate Vacuum Level: The ultimate vacuum level is the lowest pressure that can be achieved in the chamber. It depends on the design and performance of the vacuum pump. Higher-quality vacuum pumps can achieve lower ultimate vacuum levels, which are important for applications requiring higher levels of vacuum or for processes that are sensitive to residual gases.
4. Leak Detection and Gas Removal: Vacuum pumps can also assist in leak detection and gas removal within the chamber. By continuously evacuating the chamber, any leaks or gas ingress can be identified and addressed promptly. This ensures that the chamber maintains the desired vacuum level and minimizes the presence of contaminants or unwanted gases.
5. Contamination Control: Some vacuum pumps, such as oil-sealed pumps, use lubricating fluids that can introduce contaminants into the chamber. These contaminants may be undesirable for certain applications, such as semiconductor manufacturing or research. Therefore, the choice of vacuum pump and its potential for introducing contaminants should be considered to maintain the required cleanliness and purity of the vacuum chamber.
6. Noise and Vibrations: Vacuum pumps can generate noise and vibrations during operation, which can impact the performance and usability of the vacuum chamber. Excessive noise or vibrations can interfere with delicate experiments, affect the accuracy of measurements, or cause mechanical stress on the chamber components. Selecting vacuum pumps with low noise and vibration levels is important for maintaining optimal chamber performance.
It’s important to note that the specific requirements and performance factors of a vacuum chamber can vary depending on the application. Different types of vacuum pumps, such as rotary vane pumps, dry pumps, or turbomolecular pumps, offer varying capabilities and features that cater to specific needs. The choice of vacuum pump should consider factors such as the desired vacuum level, pumping speed, ultimate vacuum, contamination control, noise and vibration levels, and compatibility with the chamber materials and gases used.
In summary, vacuum pumps have a significant impact on the performance of vacuum chambers. They enable the creation and maintenance of the desired vacuum level, affect the pumping speed and ultimate vacuum achieved, assist in leak detection and gas removal, and influence contamination control. Careful consideration of the vacuum pump selection ensures optimal chamber performance for various applications.
暖通空调系统中真空泵的用途是什么?
在暖通空调(HVAC)系统中,真空泵起着至关重要的作用。下面是详细说明:
暖通空调系统中真空泵的作用是去除制冷剂管路和系统本身中的空气和湿气。暖通空调系统,尤其是依靠制冷的系统,需要在特定的压力和温度条件下运行,以促进热量的传递。为确保最佳性能和效率,必须从系统中排出任何不可冷凝的气体、空气和湿气。
以下是暖通空调系统中使用真空泵的主要原因:
1.除湿:由于系统安装、泄漏或维护不当等各种因素,暖通空调系统中可能存在湿气。当湿气与制冷剂结合时,会导致结冰、系统效率降低以及系统部件的潜在损坏等问题。真空泵通过创造低压环境来帮助去除湿气,从而使湿气沸腾并变成蒸汽,有效地将其从系统中抽空。
2.消除空气和不凝性气体:空气和不凝性气体(如氮气或氧气)可能在安装、维修过程中或通过泄漏进入暖通空调系统。这些气体会阻碍制冷过程、影响传热并降低系统性能。通过使用真空泵,技术人员可以排空空气和不凝性气体,确保系统在设计的制冷剂和压力水平下运行。
3.准备制冷剂充注:在向暖通空调系统充注制冷剂之前,关键是要抽真空,以清除任何杂质,确保系统清洁,为制冷剂的最佳循环做好准备。通过使用真空泵对系统进行抽真空,技术人员可确保制冷剂进入清洁可控的环境,从而降低系统故障的风险并提高整体效率。
4.泄漏检测:真空泵也用于暖通空调系统的泄漏检测。抽空系统后,技术人员可以监测压力是否保持稳定。如果压力明显下降,则表明存在泄漏,技术人员可在向系统注入制冷剂之前查明并修复泄漏。
总之,真空泵在暖通空调系统中起着至关重要的作用,它可以去除湿气、排除空气和不凝性气体、为制冷剂充注做好准备并帮助检测泄漏。这些功能有助于确保最佳的系统性能、能效和使用寿命,同时还能降低系统故障和损坏的风险。
