?1、工作時(shí)柱塞不能在泵內(nèi)移動,它只能將液體從一個截面向另一截面進(jìn)行移動,這就使在泵的出口和泵殼之間形成了一個空氣間隙,這樣可避免油從間隙中逸出而污染介質(zhì) 在柱塞的上下側(cè)都裝有導(dǎo)流管,從而使在泵的出口和泵殼之間形成了一個空氣間隙。
柱塞與油缸連接,泵內(nèi)不需要油潤滑,但必須保持泵殼、進(jìn)油管和出油管與水平面之間的間隙大于3mm所以柱塞泵是一種很適合輸送油品和具有磨擦性介質(zhì)的泵種隨著工藝的發(fā)展還可應(yīng)用于高粘度介質(zhì),但其缺點(diǎn)是:由于需要使用大量空氣,并且在工作過程中會有少量污物從間隙中逸出而污染介質(zhì)。
為此在目前用在有磨擦性質(zhì)的工況上已很少使用 2、柱塞泵具有自吸功能,能通過液面波動和自動補(bǔ)償振動來控制泵軸在泵內(nèi)的旋轉(zhuǎn)角 由于泵體內(nèi)設(shè)有吸入口,液面波動可以控制可調(diào)節(jié)進(jìn)料管與出口管的距離可根據(jù)需要調(diào)節(jié)進(jìn)料管的角度。
液面變化時(shí),可改變進(jìn)給量從而調(diào)節(jié)泵的揚(yáng)程 3、與離心泵相比,柱塞泵具有結(jié)構(gòu)緊湊,體積小,重量輕,效率高,維護(hù)方便的特點(diǎn) 一般離心泵重量只有幾十公斤,柱塞泵只有幾十公斤這樣有利于泵的結(jié)構(gòu)緊湊,提高了工作效率。
但是這一特點(diǎn)也給故障檢修帶來了困難由于柱塞泵輸送氣體時(shí)有一定的氣隙當(dāng)氣體從出口吸入后就會膨脹成氣體柱塞在高溫下,空氣柱塞會膨脹并使液體在柱塞之間或液液兩腔之間作氣體流動,這時(shí)就會出現(xiàn)高壓氣體沖擊液體,從而引起泵體發(fā)生爆裂,嚴(yán)重時(shí)會造成泵殼內(nèi)泄漏。
因此必須注意柱塞泵的維護(hù)與檢修 90-R-100-KP-1-BC-80-L-3-S1-F-03-GBA-32-32-24 90R100KP1BC80L3S1F03GBA323224 90-R-100-KP-1-BC-80-L-4-S1-E-00-EBC-35-35-24 90R100KP1BC80L4S1E00EBC353524 90-R-100-KP-1-BC-80-L-4-S1-F-03-EBC-29-29-24 90R100KP1BC80L4S1F03EBC292924 90-R-100-KP-1-BC-80-P-3-F1-E-00-GBA-35-35-24 90R100KP1BC80P3F1E00GBA353524 90-R-100-KP-1-BC-80-P-3-F1-E-03-GBA-14-35-24 90R100KP1BC80P3F1E03GBA143524 90-R-100-KP-1-BC-80-P-3-F1-E-03-GBA-23-26-24 90R100KP1BC80P3F1E03GBA232624 90-R-100-KP-1-BC-80-P-3-F1-E-03-GBA-35-35-24 90R100KP1BC80P3F1E03GBA353524 90-R-100-KP-1-BC-80-P-3-F1-E-03-GBA-42-42-24 90R100KP1BC80P3F1E03GBA424224 90-R-100-KP-1-BC-80-P-3-F1-F-00-GBA-45-14-24 90R100KP1BC80P3F1F00GBA451424 90-R-100-KP-1-BC-80-P-3-F1-F-03-EBC-29-29-24 90R100KP1BC80P3F1F03EBC292924 90-R-100-KP-1-BC-80-P-3-S1-D-00-GBA-40-40-24 90R100KP1BC80P3S1D00GBA404024 90-R-100-KP-1-BC-80-P-3-S1-D-03-GBA-40-40-24 90R100KP1BC80P3S1D03GBA404024 90-R-100-KP-1-BC-80-P-3-S1-D-04-GBA-40-40-24 90R100KP1BC80P3S1D04GBA404024 90-R-100-KP-1-BC-80-P-3-S1-E-03-GBA-38-38-24 90R100KP1BC80P3S1E03GBA383824 90-R-100-KP-1-BC-80-P-3-S1-E-03-GBA-42-42-24 90R100KP1BC80P3S1E03GBA424224 90-R-100-KP-1-BC-80-P-3-S1-F-03-GBA-29-29-24 90R100KP1BC80P3S1F03GBA292924 90-R-100-KP-1-BC-80-P-3-S1-F-03-GBA-35-35-24 90R100KP1BC80P3S1F03GBA353524 90-R-100-KP-1-BC-80-P-3-T2-E-03-GBA-38-38-24 90R100KP1BC80P3T2E03GBA383824 90-R-100-KP-1-BC-80-P-3-T2-E-03-GBA-42-42-24 90R100KP1BC80P3T2E03GBA424224 90-R-100-KP-1-BC-80-R-3-F1-F-03-EBC-29-29-24 90R100KP1BC80R3F1F03EBC292924 90-R-100-KP-1-BC-80-R-3-F1-F-03-EBC-35-35-24 90R100KP1BC80R3F1F03EBC353524 90-R-100-KP-1-BC-80-R-3-F1-F-03-GBA-23-23-24 90R100KP1BC80R3F1F03GBA232324 90-R-100-KP-1-BC-80-R-3-F1-F-03-GBA-35-35-24 90R100KP1BC80R3F1F03GBA353524 90-R-100-KP-1-BC-80-R-3-F1-F-03-GBA-40-40-24 90R100KP1BC80R3F1F03GBA404024 90-R-100-KP-1-BC-80-R-3-S1-E-03-GBA-35-35-20 90R100KP1BC80R3S1E03GBA353520 90-R-100-KP-1-BC-80-R-3-S1-F-03-EBC-35-35-24 90R100KP1BC80R3S1F03EBC353524 90-R-100-KP-1-BC-80-R-3-S1-F-03-GBA-29-20-24 90R100KP1BC80R3S1F03GBA292024 90-R-100-KP-1-BC-80-R-4-C7-E-02-GBA-35-35-24 90R100KP1BC80R4C7E02GBA353524 90-R-100-KP-1-BC-80-R-4-S1-E-00-GBA-32-35-24 90R100KP1BC80R4S1E00GBA323524 90-R-100-KP-1-BC-80-R-4-S1-E-03-GBA-42-42-24 90R100KP1BC80R4S1E03GBA424224 。
