ZB-G系列是軸承外置泵適合較惡劣的工況,較傳統(tǒng)熔體泵泵內(nèi)自潤(rùn)滑系統(tǒng),外置潤(rùn)滑更能適用于惡劣工況下使用。當(dāng)聚合物里含有較多不可熔物質(zhì)時(shí),如碳酸鈣粉粒、碳粒、玻纖等,長(zhǎng)時(shí)間高溫下易在潤(rùn)滑流道內(nèi)聚結(jié),把潤(rùn)滑通路堵住或堵死,一旦潤(rùn)滑系統(tǒng)行不成通路,齒輪軸和軸套干磨極易抱死,而采用外置潤(rùn)滑型熔體泵這個(gè)問(wèn)題就可迎刃而解了,采用四個(gè)進(jìn)口軸承在泵體外部將主動(dòng)軸和從動(dòng)軸固定,根據(jù)物料的粘度和使用溫度對(duì)熔體泵內(nèi)部結(jié)構(gòu)及密封和配合間隙做相應(yīng)的針對(duì)優(yōu)化。
特點(diǎn):流道短以減少物料停留時(shí)間
應(yīng)用領(lǐng)域:適用于PS, PP, PET, PVC, PC, PMMA, PA,ABS,PE-LLD等工藝中
ZB-G pump for more harsh conditions, compared with the traditional melt pump pump self-lubricating system, external lubrication is more suitable for use under harsh conditions. When the polymer contains more non-fusible material, such as calcium carbonate particles, carbon particles, glass fiber, etc., for a long time at high temperatures easy to coalescence in the lubrication channel, the lubrication path blocked or blocked, once the lubrication system No access, gear shaft and shaft dry grinding easy to lock, and the use of external lubrication type melt pump can solve this problem, the use of four imported bearings in the pump outside the main shaft and driven shaft fixed, according to The viscosity and temperature of the material are optimized for the internal structure of the melt pump and the sealing and mating clearance.
