YUKEN油研电磁阀特点

YUKEN油研电磁阀的主要特点电磁阀外漏堵绝，内漏易控，使用安全。内外泄漏是危及安全的要素。其它自控阀通常将阀杆伸出，由电动、气动、液动执行机构控制阀芯的转动或移动。这都要解决长期动作阀杆动密封的外泄漏难题；唯有电磁阀是用电磁力作用于密封在电动调节阀隔磁套管内的铁芯完成，不存在动密封，所以外漏易堵绝。电动阀力矩控制不易，容易产生内漏，甚至拉断阀杆头部；电磁阀的结构型式容易控制内泄漏，直至降为零。所以，电磁阀使用特别安全，尤其适用于腐蚀性、有毒或高低温的介质。
YUKEN油研电磁阀系统简单，便接电脑，价格低廉。电磁阀本身结构简单，价格也低，比起调节阀等其它种类执行器易于安装维护。更显著的是所组成的自控系统简单得多，价格要低得多。由于电磁阀是开关信号控制，与工控计算机连接十分方便。在当今电脑普及，价格大幅下降的时代，电磁阀的优势就更加明显。SMC电磁阀动作快递，功率微小，外形轻巧。电磁阀响应时间可以短至几个毫秒，即使是先导式电磁阀也可以控制在几十毫秒内。由于自成回路，比之其它自控阀反应更灵敏。设计得当的电磁阀线圈功率消耗很低，属节能产品；还可做到只需触发动作，自动保持阀位，平时一点也不耗电。电磁阀外形尺寸小，既节省空间，又轻巧美观。电磁阀调节精度受限，适用介质受限。电磁阀通常只有开关两种状态，阀芯只能处于两个极限位置，不能连续调节，（力图突破的新构思不少，但还都处于试验试用阶段）所以调节精度还受到一定限制。YUKEN油研电磁阀对介质洁净度有较高要求，含颗粒状的介质不能适用，如属杂质须先滤去。另外，粘稠状介质不能适用，而且，特定的产品适用的介质粘度范围相对较窄。YUKEN电磁阀型号多样，用途广泛。电磁阀虽有先天不足，优点仍十分突出，所以就设计成多种多样的产品，满足各种不同的需求，用途极为广泛。电磁阀技术的进步也都是围绕着如何克服先天不足，如何更好地发挥固有优势而展开。

YUKEN油研液压泵特点

YUKEN油研叶片泵是专为低噪声工作而开发的高压高性能叶片泵，内部采用圆弧叶片，以提高定子和叶片的寿命；定子采用高次方无冲击过渡曲线，使压力和流量脉动最小，噪声更低。本公司这一系列的叶片泵产品，具有结构合理，脉动小，噪声低，可靠性高的特点。
油研YUKEN柱塞泵具有容积效率高，节能，控制简单，灵活等特点。主要用于注塑机械、压铸机械、橡胶机机械，塑料机械等机械类！

YUKEN had its beginning in 1929 as an auto repair facility, started by Mr. Uichi Yuki. It grew into a machine tool builder in 1931. Hydraulic honing machines followed in 1940. The manufacturing of this equipment brought about the development of hydraulic vane pumps and control valves, which established a base for the manufacturing of hydraulic equipment.A Company by the name of Yuatsukiki Kenkyujo was formed in 1952, with $12,000.00 capitalization. In 1956 this company was reorganized as YUKEN KOGYO Co. Ltd. with $60,000.00 capitalization. A sales office was established in Osaka, Japan in 1959 followed by a factory in Fujisawa in 1960. In 1961 YUKEN Machinery Co. Ltd. was formed.

1962 saw the company listed on the Tokyo Stock Exchange with $2,000,000.00 capitalization. In 1964 the main office was moved to its present location in Fujisawa. A sales office was established in Tokyo in 1967. A manufacturing joint-venture commenced operations in 1969 under the name Taiwan Hydraulics Mfg. Co., Ltd.The stock of YUKEN was added to the Osaka Stock Exchange in 1969 with $9,100,000.00 capitalization. In forty (40) years YUKEN went from an auto repair shop to a publicly traded company.Since then YUKEN has continued to expand its line of hydraulic products as well as certain types of machinery dependent on hydraulic power. Currently, YUKEN has offices throughout Japan, and has expanded considerably with offices, plants and affiliated business relationships in the United Kingdom, Hong Kong, China, Taiwan, India and now the United States and Canada.YUKEN Kogyo Co. Ltd. is publicly traded on two (2) stock exchanges. They employ eight hundred (800) people and have sales exceeding ¥20,000,000,000.YUKEN has enjoyed a very successful and innovative past. Its future is directed toward significant growth and achievements in the Fluid Power Industry.
