描述

专为在恶劣条件下操作而设计

TC双级液环泵系列是我们专为冷凝器抽真空工作设计的二代双级泵。整体式双级叶轮设计的真空度可低至0.8 inHgA（30 mbar abs)，*对压力比单级泵低约40％。

TC液环真空泵用于化工、石化和电力行业。TC泵凭借其整体式双级转子，能够浓缩工艺产生的蒸汽并回收或处理它们。

锥形端口和转子配置

Nash的可变锥形端口设计于1932年获得自主研发设计，使压缩力抵消转子和轴的重量，从而尽量减少轴承的运行负荷。可变端口在整个工作范围内优化泵的性能。凭借不断创新，Nash的自主研发设计设计具有以下特点：

可选择的凸轮清洗方法，以尽量减小涉及固体的工作中侵蚀造成的损害

大压差能力

GSV设计可更大限度地减少气体从排放口漏到入口，从而提高容量，特别是在深度真空时

液体残留物耐受性高

侧面排放，以尽量减少满液启动的可能

自吸设计可消除在再循环系统中使用增压泵

可行、快效、性能优佳

TC通过经过证明、可行的锥形液环泵设计提供优佳的性能和可行性。TC的转子叶片被覆盖，以提高强度和可行性。

正在申请自主研发设计的抗气蚀技术可用于全部TC型号，并且可在易于产生气蚀的操作中使泵的使用寿命延长一倍。TC泵的两级经过设置，使得由于压力作用到每级上，导致作用在轴上的力相反，从而减小轴承上的负荷。

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.
