A4VSO泵具有泵具有噪音低、體積小、自吸能力好、可靠性高等優(yōu)點。在閉式系統(tǒng)上應(yīng)用，油泵變量過零位時一般柱塞泵都有托盤現(xiàn)象，唯獨D-A4VSO泵有效解決此類問題，因補油泵、控制泵可以串接、控制閥可以集成在泵蓋上，其結(jié)構(gòu)非常緊湊;另外，比例泵均帶有位移傳感器閉式反饋回路，其零位控制精度非常高。廣泛應(yīng)用于：冶金行業(yè)、鍛壓行業(yè)、船舶行業(yè)、船舶等等領(lǐng)域。A4VSO系列規(guī)格有40、71、125、180、250:;變量形式有恒壓，恒功率、液動、負載感應(yīng)、比例、伺服、壓力流量復(fù)合控制形式;有開式系統(tǒng)泵和閉式系統(tǒng)泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,

這樣，既可穩(wěn)定焊接部分，又可以去掉焊接面上的熔渣，以防腐蝕。焊接后正常的焊縫應(yīng)無氣孔、裂紋和未熔合。隱蔽安裝的塑銅管只能采取焊接連接，外露部分及與衛(wèi)生器具鑲接的部位，可以采取絲扣連接，絲扣連接的要求按鍍鋅管道的安裝方式進行。管道焊接部位應(yīng)采用熱塑材料進行包裹保護，熱塑材料應(yīng)由制造廠提供，提供的材料應(yīng)能達到防腐要求。用布及砂紙刷凈銅管上氧化物，表面光滑，無砂眼氣泡。管道焊接完成，除去氧化層后涂清漆保護。
