为了能够预先及时地对我公司所有的千斤顶进行逐个检验,并随即调换已损坏的零配件,充分发挥每个千斤顶的作用,从而减少了设备的添置费用,为此,我公司把研制千斤顶工作性能的测试装置列为1988年度科研课题。经过一年的努力基本上完成了试制工作,并由市住宅总公司组织和主持技术鉴定,认为该装置能够有效地测出新旧滑模千斤顶在额定荷载条件下的实际行程高度、滑移量,并可检验其密封性能等主要技术参数。凡经该装置检测后的千斤顶应用于滑模
In order to be able to examine all the jacks of our company one by one in time, and then replace the damaged spare parts, give full play to the role of each jack, thereby reducing the cost of the equipment to add, for this reason, our company to develop the working performance of the jack The test device was listed as a 1988 research project. After one year’s efforts, the trial production was basically completed, and the Municipal Housing Corporation organized and conducted the technical appraisal. It is believed that the device can effectively measure the actual stroke height and slip amount of the new and old sliding mode jacks under the rated load conditions. And can test its sealing performance and other major technical parameters. The jacks tested by this device are applied to sliding mode
