上海河山泵业有限公司(原上海河山液压机械厂)成立于八十年代,其后重组改为上海河山泵业有限公司,国内泵阀生产规模较大的研究开发制造基地之一,是一家集科研开发、设计咨询、销售于一体的经济实体。 公司自成立以来本着以人才为资本,以技术为动力,以客户需求为己任的经营理念,坚持“以客户为中心”的服务宗旨,产品不断优化、推陈出新。 目前,我厂生产的配件是我国配套范围泛单位之一,产品远销全国二十四个省、市、自治区,部分产品齿轮油泵、螺杆泵已实现出口,水泵广泛应用于化工、医药、食品、轻工、染料等工业中的蒸馏、结晶、干燥、浓缩、过滤以及真空冶炼的除汽、电气工业中的浸渗等,企业连续十几年被授于“重合同,守信用”荣誉称号,深受广大客户的好评。 在新的世纪里,我们决心以新的更高的起点研究开发新产品,以科技求发展,进一步推进企业上规模;产品上档次;管理上水平。坚持“用户、以诚为本,信誉至上,*”的宗旨,为广大用户提供的服务,为实现辉煌的明天而携手共进。 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恒压变量柱塞泵 产品信息
PCY14-1B恒压变量柱塞泵,输出压力小于调定恒压力时,全排量输出压力油,即定量输出,在输出油液的压力达到调定压力时,就自动地调节泵流量,以保持该恒压力,满足系统的要求。变量柱塞泵的输出恒压值,根据需要,在调压范围内可以无级调定。泵的结构见上图,该结构将输出压力油同时通至变量活塞下腔和恒压阀的控制油入口,当输出压力小于调定恒压力时,作用在恒压阀芯上的油压推力小于调定弹簧力,恒压阀处于开启状态,压力油进入变量活塞上腔,变量活塞压在位置,泵全排量输出压力油:当柱塞泵在调定压力工作时,作用在恒压阀芯上的油压推力等于调定弹簧力,恒压阀的进排油口同时处于开启状态,使变量活塞上下腔的油压推力相等,变量活塞平衡在某一位置工作,若液压阻尼(负载)加大,油压瞬时升高,恒压阀排油口开大、进油口关小,变量活塞上腔比较下腔压力降低、变量活塞向上移动,泵的流量减小,直至压力下降到调定恒压力,这时变量活塞在新的平衡位置工作。反之,若液压阻尼(负载)减小,油压瞬时下降,恒压阀进油口开大,排油口关小,变量活塞上腔比较下腔油压升高,变量活塞向下移动,柱塞泵的流量增大,直至压力上升至调定恒压力。
