特點(diǎn)和用途:
為了滿足電力、冶金、煤炭等行業(yè)發(fā)展需要,針對(duì)除灰除渣及渣漿輸送工況的特點(diǎn),在多年渣漿泵設(shè)計(jì)制造經(jīng)驗(yàn)基礎(chǔ)上,廣泛吸取國(guó)內(nèi)外先進(jìn)技術(shù)和研制成果,我公司設(shè)計(jì)開(kāi)發(fā)了我國(guó)最新一代大流量、高揚(yáng)程、可多級(jí)串聯(lián)的ZGB系列渣漿泵。該系列產(chǎn)品的主要技術(shù)特點(diǎn)如下:
1. 采用現(xiàn)代CAD設(shè)計(jì)方法,水力性能優(yōu)良,效率高和磨損率低;
2. 流道寬暢,抗堵塞性能好,汽蝕性能優(yōu)越;
3. 采用付葉輪加填料組合式密封或機(jī)械密封,確保渣漿無(wú)泄露;
4. 可靠性設(shè)計(jì),保證了整機(jī)平均無(wú)故障工作時(shí)間(MTBF)大幅度提高;
5. 采用稀油潤(rùn)滑公制軸承,合理設(shè)置潤(rùn)滑與冷卻系統(tǒng),保證軸承在低溫下運(yùn)行;
6. 過(guò)流部件采用特殊材質(zhì),耐磨耐腐蝕性能好;經(jīng)特殊處理,可用于海水除灰及海水和鹽霧電化學(xué)腐蝕工況;
7. 在允許的壓力范圍內(nèi),可以多級(jí)串聯(lián)使用,其允許最大工作壓力為3.6Mpa。
該系列渣漿泵產(chǎn)品具有結(jié)構(gòu)合理、效率高、運(yùn)行可靠和維修方便等優(yōu)點(diǎn),廣泛適用于電力、冶金、礦山、煤炭、建材、化工等工業(yè)部門(mén)輸送磨蝕性或腐蝕性渣漿,特別是電廠灰渣。
