上海河山泵業(yè)有限公司(原上海河山液壓機(jī)械廠)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(nèi)泵閥生產(chǎn)規(guī)模較大的研究開發(fā)制造基地之一,是一家集科研開發(fā)、設(shè)計(jì)咨詢、銷售于一體的經(jīng)濟(jì)實(shí)體。 公司自成立以來本著以人才為資本,以技術(shù)為動力,以客戶需求為己任的經(jīng)營理念,堅(jiān)持“以客戶為中心”的服務(wù)宗旨,產(chǎn)品不斷優(yōu)化、推陳出新。 目前,我廠生產(chǎn)的配件是我國配套范圍泛單位之一,產(chǎn)品遠(yuǎn)銷全國二十四個(gè)省、市、自治區(qū),部分產(chǎn)品齒輪油泵、螺桿泵已實(shí)現(xiàn)出口,水泵廣泛應(yīng)用于化工、醫(yī)藥、食品、輕工、染料等工業(yè)中的蒸餾、結(jié)晶、干燥、濃縮、過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(xù)十幾年被授于“重合同,守信用”榮譽(yù)稱號,深受廣大客戶的好評。 在新的世紀(jì)里,我們決心以新的更高的起點(diǎn)研究開發(fā)新產(chǎn)品,以科技求發(fā)展,進(jìn)一步推進(jìn)企業(yè)上規(guī)模;產(chǎn)品上檔次;管理上水平。堅(jiān)持“用戶、以誠為本,信譽(yù)至上,*”的宗旨,為廣大用戶提供的服務(wù),為實(shí)現(xiàn)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(diào)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(dá)到調(diào)定壓力時(shí),就自動地調(diào)節(jié)泵流量,以保持該恒壓力,滿足系統(tǒng)的要求。變量柱塞泵的輸出恒壓值,根據(jù)需要,在調(diào)壓范圍內(nèi)可以無級調(diào)定。泵的結(jié)構(gòu)見上圖,該結(jié)構(gòu)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(dāng)輸出壓力小于調(diào)定恒壓力時(shí),作用在恒壓閥芯上的油壓推力小于調(diào)定彈簧力,恒壓閥處于開啟狀態(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(dāng)柱塞泵在調(diào)定壓力工作時(shí),作用在恒壓閥芯上的油壓推力等于調(diào)定彈簧力,恒壓閥的進(jìn)排油口同時(shí)處于開啟狀態(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(fù)載)加大,油壓瞬時(shí)升高,恒壓閥排油口開大、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,泵的流量減小,直至壓力下降到調(diào)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(fù)載)減小,油壓瞬時(shí)下降,恒壓閥進(jìn)油口開大,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,柱塞泵的流量增大,直至壓力上升至調(diào)定恒壓力。
