液環(huán)真空泵

小氣量，船用

氣量10至75 ACFM（17至130 m3/h）

50多年來(lái)，NASH一直為船上起動(dòng)灌注應(yīng)用提供真空泵和成套設(shè)備，并繼續(xù)為這個(gè)領(lǐng)域提供廣泛的經(jīng)典產(chǎn)品。這些泵緊密連接到船用電機(jī)，氣量范圍從10至75 ACFM（17至130 m3/h）。

描述

單級(jí)MD570、MD620、MHC和MHF系列可選擇多種材料，包括青銅、銅鎳和不銹鋼。

 如需更高的真空度，雙級(jí)AT34和AT64泵的容量范圍為40至75 ACFM（70至130 m3/ h）。

 Nash起動(dòng)閥的可行性和耐用性經(jīng)過(guò)50多年證明，專門設(shè)計(jì)以用于真空泵啟動(dòng)系統(tǒng)。起動(dòng)閥是一種適用于海上應(yīng)用的浮閥。只要不存在液體，它具有從全部入口連接到真空出口連接的開(kāi)放通道。當(dāng)液體進(jìn)入起動(dòng)閥體時(shí)，浮力浮漂上升并關(guān)閉閥門。

Liquid Ring Vacuum Pump

Small Capacity, Marine Duty

Capacity 10 to 75 ACFM (17 to 130 m3/h)

NASH has been providing vacuum pumps and packages in shipboard priming applications for over 50 years and continues to offer a wide range of classic products for this service. These pumps are provided close coupled to a marine duty motor have capacities ranging from 10 to 75 ACFM (17 to 130m3/h).

The single stage MD570, MD620, MHC, and MHF series are available in a variety of materials including bronze, copper, nickel, and stainless steel.

If deeper vacuum is required, the two stage AT34 & AT64 pumps are available with capacities ranging from 40 to 75 ACFM (70 to 130 m3/h).

Proven to be dependable and durable for over 50 years, Nash’s priming valves are designed specifically to be used in vacuum pump priming systems. The priming valve is a float valve ideal for marine applications. It has an open passage from all inlet connections through to the vacuum outlet connection as long as no liquid is present. When liquid enters the priming valve body, the buoyant float rises and closes the valve.
