中發(fā)工業(yè)IPD電源REL-110-2004報(bào)價(jià)

曾獲重大科技成果項(xiàng)目,并獲教委科技進(jìn)步三等獎(jiǎng)。圓弧齒輪在兩嚙合齒廓間為一點(diǎn)連續(xù)接觸,不會(huì)產(chǎn)生困油現(xiàn)象,解決了漸開線齒輪泵因困油現(xiàn)象導(dǎo)致泵的振動(dòng)、噪聲、軸承負(fù)載增大等現(xiàn)象。因此保溫圓弧齒輪泵具有效率、噪聲低,并具有良好的節(jié)能效果。本系列保溫圓弧齒輪泵主要有齒輪、軸、泵體、泵蓋、軸承套、軸端密封等組成。齒輪采用雙圓弧正弦曲線齒形制造。它與漸開線齒輪相比突出的優(yōu)點(diǎn)是齒輪嚙合過程中齒廓面沒有相對(duì)滑動(dòng),所以齒面無磨損,運(yùn)轉(zhuǎn)平穩(wěn),無因液現(xiàn)象,噪音低、壽命長、效率高。

此回路可替代標(biāo)準(zhǔn)的一次流量控制回路而獲得大輸出流量。因無載回路的壓力低于定值一次流量控制方案,故回路溫升低、無載功耗小。負(fù)載傳感比列流量控制閥與一次流量控制閥一樣,其典型應(yīng)用是動(dòng)力轉(zhuǎn)向機(jī)構(gòu)。旁路流量控制其優(yōu)點(diǎn)是,通過回路規(guī)模來控制大調(diào)整流量,降低成本;將泵和閥組合成一體,并通過泵的旁通控制,使回路壓力降至低,從面減少管路及其泄漏。對(duì)于旁路流量控制,不論泵的轉(zhuǎn)速或工作壓力高低,泵總按預(yù)定大值向系統(tǒng)供液,多余部分排回油箱或泵的入口。

反應(yīng)釜注意磁力反應(yīng)釜使用須知在磁力反應(yīng)釜操作前,應(yīng)仔細(xì)檢查有無異狀,在反應(yīng)釜正常運(yùn)行中,不得打開上蓋和觸及板上之接線端子,以免觸電。應(yīng)定期對(duì)磁力反應(yīng)釜測量儀表進(jìn)行校準(zhǔn),以保證準(zhǔn)確可靠地工作。磁力反應(yīng)釜升溫速度不宜太快,加壓亦應(yīng)緩慢進(jìn)行,尤其是反應(yīng)釜攪拌速度,只允許緩慢升速。如遇停電,應(yīng)即將調(diào)速旋鈕調(diào)回零位。磁力反應(yīng)釜不得速冷,以防過大的溫差壓力造成損壞。磁力反應(yīng)釜運(yùn)轉(zhuǎn)時(shí),聯(lián)軸器與釜蓋間的水夾套必須通冷卻水,以控制反應(yīng)釜磁鋼的工作溫度,避免退磁。壓縮空氣排盡后,關(guān)閉排氣閥。此時(shí)濾機(jī)內(nèi)無壓力,可以開蓋。清洗袋式過濾器袋式過濾器如繼續(xù)過濾同一種液體,無須清洗。但如果過濾其它種類的液體,仍需清洗機(jī)器后方可使用。O型密封圈的保養(yǎng)及更換保養(yǎng):使用時(shí)O型密封圈要對(duì)準(zhǔn)O型槽放入,避免不當(dāng)?shù)臄D壓致使O型密封圈變形;不過濾時(shí),O型密封圈必須取出擦拭干凈,否則殘液凝固后附著在其表面,導(dǎo)致硬化,密封性變差。更換:若O型密封圈已老化或破損,請(qǐng)及時(shí)更換。
