Hydraulic cylinders in rows technology to prevent air pollution caused by the invasion of the hydraulic cylinder to prevent air intrusion internal hydraulic cylinder hydraulic cylinder internal cause major pollution pollution reason is because solid impurities, water, oil and other air into the system, such as hydraulic cylinders 200 tons of Baotou, in addition to the use of changes in physical and chemical properties of the process of moving parts to wear and hydraulic oil will lead to contamination of the hydraulic cylinder. So how to prevent air intrusion hydraulic cylinders inside it? Prevent air intrusion should note the following points: 1, according to the random after repairs and oil changes for excluding air from the system to normal operation. 2, the oil pump drive shaft seal should be well 50t hydraulic cylinder manufacturer, to pay attention to where the seals should be replaced using the "lips" genuine seal, can not use the "single-lip" seal instead, because the "single lip" seal only one-way closure 300t hydraulic oil quality is good, do not have the gas sealing function. Hydraulic pump consecutive "cavitation" noise, such as elevated oil tank automatic fault hydraulic cylinders, hydraulic pumps repair process upon inquiry, found that the hydraulic pump drive shaft seal is the misuse of the "single-lip" caused by hydraulic cylinder seals the inner wall of the aperture measurements are generally direct measurement or indirect measurement. Direct measurement using two or three-point positioning, direct measurement of the aperture method. Hydraulic cylinder direct measurement commonly used measurement tools inside micrometer, universal length measuring instrument, horizontal length measuring instrument, universal length measuring instrument and the inside diameter micrometer, flexible coordinate measuring machine and other special aperture measurement tool, but direct measurements way low efficiency, error, and difficult for deep pore size and precision products online measurement. 10t hydraulic price of merit, quality-speed hydraulic (certified), hydraulic cylinders supplied by Dezhou City mass-velocity hydraulic machinery factory.
