Re: 自调分流集流阀
就是不知价格如何。Re: 自调分流集流阀
最近设计一液压系统也曾考虑过用不用这东西?一是性能二是价格都不明了,放弃了。Re: 自调分流集流阀
哪个公司的产品?Re: 自调分流集流阀
好象北京亿美博也有这个东东吧。有两个问题:1)该阀的同步精度是否受油问影响,如过有,那么是否有油温--同步精度曲线;
2)该阀具有压力补偿功能,那么,要在多大的压降下,同步精度才最好,换句话说,是否有压降--同步精度曲线。
看见4缸同步了。同步阀的精度5%,你用一个同步阀一分二,再分别接个同步阀,不知道最终的精度能达到多少?10%能达到不? 看见4缸同步了。同步阀的精度5%,你用一个同步阀一分二,再分别接个同步阀,不知道最终的精度能达到多少?10%能达到不 不错,总设计师俺重庆老乡。 如果4缸同步,采用3只分流集流阀,是不是第一只的流量要大于后面两只的流量?
