103、104、105、109、110、111型結(jié)構(gòu)是國(guó)內(nèi)最早生產(chǎn)、推廣和應(yīng)用的標(biāo)準(zhǔn)形式，已廣泛安裝在新老類型回旋式泵的密封腔內(nèi)。103、104、105均為內(nèi)裝內(nèi)流、非平衡型,它們適用于壓力較低的介質(zhì)。109、110、111是內(nèi)裝、內(nèi)流平衡結(jié)構(gòu)適用壓力較高，可達(dá)2.5MPa。

主要技術(shù)參數(shù)

密封介質(zhì)：水、油中等以下腐蝕性介質(zhì)。
介質(zhì)溫度：-20℃--+150℃
介質(zhì)壓力:0-0.8MPa
線速度: ≤20m/sec

The 103, 104, 105, 109, 110, 111 structures are the earliest standard forms of production, promotion and application in China, and have been widely installed in the sealing cavities of new and old rotary pumps. 103, 104 and 105 are all built-in internal flow and non-equilibrium type, which are suitable for medium with low pressure. 109, 110 and 111 are built-in and internal flow balanced structures, with high applicable pressure up to 2.5MPa.

Main technical parameters

Sealing medium: corrosive medium below water and oil.

Medium temperature: - 20 ℃ - + 150 ℃

Medium pressure: 0-0.8Mpa

Linear speed: ≤ 20m / sec
