設計原則

TRIVAC B 幫浦使用注入幫浦腔室的油來密封、潤滑和冷卻幫浦。潤滑系統可在高進氣壓力 (最大 1000 mbar 絕對壓力) 下持續運行。這讓它擁有從大氣壓到極限壓力寬廣的工作能力。製程氣體攜帶的油在油箱中分離。

各式各樣的配件包括各種類型的排氣過濾器，能夠捕捉細油霧，然後再隨製程氣體一起運輸。加裝機油回流系統的選購配件可將過濾後的機油回送到幫浦，讓模組化 TRIVAC B 系統趨於完整。

堅固耐用的設計

TRIVAC B 系列專為延長正常運行時間和高耐用性而設計。內體由數個獨立零件組裝而成，沒有密封部件。零件以定位銷固定以確保零件可輕鬆重複組裝。

防返油閥

TRIVAC B 幫浦配備了一個防返油閥，該閥位於幫浦的入口處。該閥門由油壓進行液壓控制，並在幫浦停止時非常快速地關閉。這可以防止幫浦回壓時真空腔室中的壓力上升。此外，還能讓機油流回腔體的情況降至最低。

整合式通道冷卻

TRIVAC B D16B 至 D65B 的尺寸具備整合式通道冷卻系統並配有額外的風扇，可直接由馬達驅動。此功能可讓 TRIVAC B 在恆定溫度下運作，並具有高水蒸耐受度。

雜音低

TRIVAC B 幫浦的智慧型設計將振動產生的噪音降至最低。所有尺寸均配備低噪音馬達，透過彈性連軸器與幫浦本體相連，以避免工作台產生額外的噪音。

整合式機油幫浦

所有 TRIVAC B 幫浦均配備整合式機油幫浦，確保機油潤滑不受進氣壓力影響。因此幫浦能以 1000 mbar 持續操作。連續潤滑可創造大型的有效儲油槽，即使在最低油位下，幫浦仍可安全操作。

Leybold TRIVAC B oil sealed double stage vane pumps are well known and being used in all areas of vacuum engineering and are equally suited for both industrial production and research applications. The TRIVAC B pumps, used to generate a rough and medium vacuum or as backing pumps in pump combinations with Roots vacuum pumps or high vacuum pumps, have the ability of pumping down from the atmosphere.

The TRIVAC B pump excels with a high vacuum performance by delivering a low ultimate pressure and high water vapor tolerance with an integrated gas ballast. With a low noise level and low vibration, TRIVAC B pumps do not add to the noise in your working environment. The well-proven robust design with low thermal losses and air-cooled design makes the TRIVAC B pumps portable and compact. A comprehensive range of accessories and variants are available to offer a complete solution to meet the requirements of your applications.

The TRIVAC B range is available in six different sizes with an ultimate pressure of 10^-4 mbar and a pumping speed in the range of 4 m³/h to 65 m³/h:

• TRIVAC D 4/8 B Series
• TRIVAC D 16/25 B Series
• TRIVAC D 40/65 B Series ​

User advantages

• Low ultimate pressure (10-4 mbar), continuous operation even at 1000 mbar
• Integrated gas ballast for High water vapor tolerance
• Low oil back streaming thanks to Anti-suckback valve controlled via the oil pressure
• Built-in oil pump for lubrication, cooling and handling particulates
• Custom Vertical or horizontal intake and exhaust ports
• Service-friendly; Exchangeable inner body, pressure lubricated sliding bearings
• Standard variants are certified in accordance with 2014/34/EU (ATEX Category 3 inside)

Design principle

TRIVAC B pumps use oil, injected into the pump chamber, for sealing, lubrication and cooling of the pump. The lubrication system is rated for continuous operation at high intake pressures (max. 1000 mbar abs.). This leads to the capability of being used in a versatile manner from atmospheric down to ultimate pressure. The oil carried with the process gas is separated in the oil box.

A wide range of accessories include various types of exhaust filters capable of trapping fine oil mist, which is then transported with the process gas. The option of adding an oil return system completes the modular TRIVAC B range by supplying the filtered oil back into the pump.

Rugged design

The TRIVAC B range has been designed for an extended uptime and high robustness. The inner body is assembled from individual parts without sealing components. The parts are pinned in order to ensure an easy reassembly of the parts.

Anti-suckback valve

The TRIVAC B pumps are equipped with an anti-suckback valve, which is located in the intake of the pumps. The valve is hydraulically controlled by the oil pressure and closes very fast during a pump standstill. This prevents the pressure from rising in the vacuum chamberwhile the pump is vented. Additionally, it minimizes the backstreaming of the oil into the chamber.

Integrated ducted cooling

The TRIVAC B sizes D16B to D65B have an integrated ducted cooling with an additional fan, directly driven by the motor. This feature allows the TRIVAC B to operate at a constant temperature and have a high water vapor tolerance.

Low noise level

The smart design of the TRIVAC B pumps reduces vibration born noises to a minimum. All sizes are equipped with low noise motors, which are linked to the pump unit by an elastic coupling to avoid additional noise on the work floor.

Integrated oil pump

All TRIVAC B pumps are equipped with an integrated oil pump that ensures oil-lubrication independent from the inlet pressure. The pumps are therefore capable of constant operation at 1000 mbar. Continuous lubrication creates a large effective oil reservoir, which benefits from a safe operation of the pumps even with minimum oil level.
