    上海河山泵業(yè)有限公司(原上海河山液壓機械廠(chǎng))成立于八十年代,其后重組改為上海河山泵業(yè)有限公司,國內泵閥生產(chǎn)規模較大的研究開(kāi)發(fā)制造基地之一,是一家集科研開(kāi)發(fā)、設計咨詢(xún)、銷(xiāo)售于一體的經(jīng)濟實(shí)體。 公司自成立以來(lái)本著(zhù)以人才為資本,以技術(shù)為動(dòng)力,以客戶(hù)需求為己任的經(jīng)營(yíng)理念,堅持“以客戶(hù)為中心”的服務(wù)宗旨,產(chǎn)品不斷優(yōu)化、推陳出新。 目前,我廠(chǎng)生產(chǎn)的配件是我國配套范圍泛?jiǎn)挝恢?,產(chǎn)品遠銷(xiāo)全國二十四個(gè)省、市、自治區,部分產(chǎn)品齒輪油泵、螺桿泵已實(shí)現出口,水泵廣泛應用于化工、醫藥、食品、輕工、染料等工業(yè)中的蒸餾、結晶、干燥、濃縮、過(guò)濾以及真空冶煉的除汽、電氣工業(yè)中的浸滲等,企業(yè)連續十幾年被授于“重合同,守信用”榮譽(yù)稱(chēng)號,深受廣大客戶(hù)的好評。 在新的世紀里,我們決心以新的更高的起點(diǎn)研究開(kāi)發(fā)新產(chǎn)品,以科技求發(fā)展,進(jìn)一步推進(jìn)企業(yè)上規模;產(chǎn)品上檔次;管理上水平。堅持“用戶(hù)、以誠為本,信譽(yù)至上,”的宗旨,為廣大用戶(hù)提供的服務(wù),為實(shí)現輝煌的明天而攜手共進(jìn)。 Shanghai Heshan Pump Co., Ltd. (former Shanghai Heshan Hydraulic Machinery Factory) was established in the eighties, then re-changed to Shanghai Heshan Pump Co., Ltd., the domestic production of large-scale valve manufacturing base in research and development is one of a set of scientific research and development, design consulting, sales in one economic entity. Since its inception in line with talents, capital, technology-driven, customer demand as its own business philosophy. Adhere to the "customer-centric" principle of service, product constantly optimize, get rid of. At present, our factory components produced in China one of the units supporting the widest range of products are exported to the country 24 provinces, municipalities and autonomous regions, and some are gear pumps, pumps for export has been widely used in chemical, pharmaceutical, food, light industry, dye and other industries in the distillation, crystallization, drying, concentration, filtering, and vacuum refining of the inter gas, electric industry in the infiltration and so on, companies have been granted more than ten years in a row "heavy contract, keep promise" in honor title, well received by the customers. In the new century, we are determined to start a new and higher research and development of new products, technology development, further promote the business on the scale; product grade; management level. Adhere to the "customers first, sincerity-oriented, credibility first, quality assurance," the purpose, in order to provide customers with first-class services for the realization of a brilliant tomorrow hand in hand.

    PCY14-1B恒壓變量柱塞泵 產(chǎn)品信息
    PCY14-1B恒壓變量柱塞泵,輸出壓力小于調定恒壓力時(shí),全排量輸出壓力油,即定量輸出,在輸出油液的壓力達到調定壓力時(shí),就自動(dòng)地調節泵流量,以保持該恒壓力,滿(mǎn)足系統的要求。變量柱塞泵的輸出恒壓值,根據需要,在調壓范圍內可以無(wú)級調定。泵的結構見(jiàn)上圖,該結構將輸出壓力油同時(shí)通至變量活塞下腔和恒壓閥的控制油入口,當輸出壓力小于調定恒壓力時(shí),作用在恒壓閥芯上的油壓推力小于調定彈簧力,恒壓閥處于開(kāi)啟狀態(tài),壓力油進(jìn)入變量活塞上腔,變量活塞壓在位置,泵全排量輸出壓力油:當柱塞泵在調定壓力工作時(shí),作用在恒壓閥芯上的油壓推力等于調定彈簧力,恒壓閥的進(jìn)排油口同時(shí)處于開(kāi)啟狀態(tài),使變量活塞上下腔的油壓推力相等,變量活塞平衡在某一位置工作,若液壓阻尼(負載)加大,油壓瞬時(shí)升高,恒壓閥排油口開(kāi)大、進(jìn)油口關(guān)小,變量活塞上腔比較下腔壓力降低、變量活塞向上移動(dòng),泵的流量減小,直至壓力下降到調定恒壓力,這時(shí)變量活塞在新的平衡位置工作。反之,若液壓阻尼(負載)減小,油壓瞬時(shí)下降,恒壓閥進(jìn)油口開(kāi)大,排油口關(guān)小,變量活塞上腔比較下腔油壓升高,變量活塞向下移動(dòng),柱塞泵的流量增大,直至壓力上升至調定恒壓力。
