我厂是生产工程机械用变速箱的定点厂家之一,根据近年来生产实践的体会,我们对目前金属旋转密封圈的生产及供应情况有一些看法,愿提出来引起讨论。我厂现已组织生产和将要组织生产的各种机型产品中,所需用的金属旋转密封圈已达22种62单台件。据了解,全国尚有不少工程机械生产厂均需要金属旋转密封圈,所以金属旋转密封圈的需求量已构成相当可观的数字,且随着工程机械的发展,其需求量将更为可观。从国内金属旋转密封圈的生产情况看,由于科研及产品开发工作尚未跟上,目前没有形成专业化生产能力,我国自己的尺寸系列和相应的质量标准也都尚未制定。所以,国产金属旋转密封圈的质量、寿命等指标很低,这就在
Our factory is one of the fixed-point manufacturers for the production of construction machinery transmissions. According to the experience of production practice in recent years, we have some views on the current production and supply of metal rotating seals, and we would like to raise the discussion. Our factory has now organized production and will be organized production of various models of products, the required metal rotating sealing ring has reached 22 kinds of 62 single pieces. It is understood that there are still a lot of construction machinery manufacturers in the country that require metal rotating seals, so the demand for metal rotating seals has constituted a considerable number, and with the development of construction machinery, its demand will be even more impressive. From the perspective of the production of domestic metal rotary seals, due to the fact that scientific research and product development have not kept pace, there is currently no professional production capacity. Our own size series and corresponding quality standards have not yet been established. Therefore, the quality, lifespan, and other indicators of domestic metal rotary seals are very low.
