描述

專為在惡劣條件下操作而設(shè)計(jì)

TC雙級(jí)液環(huán)泵系列是我們專為冷凝器抽真空工作設(shè)計(jì)的二代雙級(jí)泵。整體式雙級(jí)葉輪設(shè)計(jì)的真空度可低至0.8 inHgA（30 mbar abs)，*對(duì)壓力比單級(jí)泵低約40％。

TC液環(huán)真空泵用于化工、石化和電力行業(yè)。TC泵憑借其整體式雙級(jí)轉(zhuǎn)子，能夠濃縮工藝產(chǎn)生的蒸汽并回收或處理它們。

錐形端口和轉(zhuǎn)子配置

Nash的可變錐形端口設(shè)計(jì)于1932年獲得自主研發(fā)設(shè)計(jì)，使壓縮力抵消轉(zhuǎn)子和軸的重量，從而盡量減少軸承的運(yùn)行負(fù)荷。可變端口在整個(gè)工作范圍內(nèi)優(yōu)化泵的性能。憑借不斷創(chuàng)新，Nash的自主研發(fā)設(shè)計(jì)設(shè)計(jì)具有以下特點(diǎn)：

?可選擇的凸輪清洗方法，以盡量減小涉及固體的工作中侵蝕造成的損害

?大壓差能力

?GSV設(shè)計(jì)可更大限度地減少氣體從排放口漏到入口，從而提高容量，特別是在深度真空時(shí)

?液體殘留物耐受性高

?側(cè)面排放，以盡量減少滿液?jiǎn)?dòng)的可能

?自吸設(shè)計(jì)可消除在再循環(huán)系統(tǒng)中使用增壓泵

可行、快效、性能優(yōu)佳

TC通過(guò)經(jīng)過(guò)證明、可行的錐形液環(huán)泵設(shè)計(jì)提供優(yōu)佳的性能和可行性。TC的轉(zhuǎn)子葉片被覆蓋，以提高強(qiáng)度和可行性。

正在申請(qǐng)自主研發(fā)設(shè)計(jì)的抗氣蝕技術(shù)可用于全部TC型號(hào)，并且可在易于產(chǎn)生氣蝕的操作中使泵的使用壽命延長(zhǎng)一倍。TC泵的兩級(jí)經(jīng)過(guò)設(shè)置，使得由于壓力作用到每級(jí)上，導(dǎo)致作用在軸上的力相反，從而減小軸承上的負(fù)荷。

Description

Designed To Operate In Harsh Conditions

The line of TC two stage liquid ring pumps is our second generation of two stage pumps designed specifically for the condenser exhaust duty. The integral two stage impeller is designed to reach vacuum levels down to 0.8 inHgA (30 mbar abs), approximately 40% lower absolute pressure than a single stage pump.

TC liquid ring vacuum pumps were created for the chemical, petrochemical, and power industries. TC pumps, with their integral two stage rotors, are able to condense vapors that come off the process and to recover or dispose of them.

Conical Porting And Rotor Configuration

Patented in 1932, Nash’s variable conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. The variable porting optimizes pump performance across the entire operating range. With constant innovation, Nash’s patented design features:

Option for lobe purge to minimize damage from erosion in duties with solids present

Large differential pressure capability

Gas scavenging feature minimizes slip of gas from discharge to inlet improving capacity, especially at deep vacuum

High liquid carryover tolerance

Side discharge to minimize chance of flooded start

Self-priming design may allow elimination of booster pump in recirculated systems

Reliable And Efficient With Proven Performance

Liquid Ring Vacuum Pump

Two Stage, TC

Capacity 100 to 2,100 ACFM (170 to 3,600 m3/h)

The NASH TC two stage liquid ring vacuum pump series offers highly reliable and efficient solutions for power, chemical, and petrochemical applications. Designed to handle large amounts of liquid carryover without difficulty, the TC pump delivers reliable, long-lasting performance under the most demanding applications. Available in 9 models, the capacities of the TC pumps range from about 100 to 2,100 ACFM (170 to 3,600 m3)

TC pumps offer superior performance and reliability through the proven reliable conical liquid ring pump design. The TC's rotor blades are shrouded to improve strength and reliability.

Patent-pending anti-cavitation technology is available in all TC models and can double useful pump life in cavitation prone operations. The two stages of the TC pump are set up so that the forces on the shaft due to compression in each stage are opposed to reducing the load on the bearings.

Looking for NASH parts, service or repairs? The TC pump model is available for quick shipment in most regions and is a part of our Unit Exchange program for pump swap out. Contact NASH Certified Service for spare parts and pump availability and pricing.
