Hydraulic cylinders, hydraulic cylinder price, quality provided by the mass-velocity speed hydraulic hydraulic. Dezhou City mass-velocity hydraulic machinery plant (www.dzzhisu.com) is a high quality business alliance Dezhou certified company, with brands such as mass-velocity, has a good reputation, honesty, service-oriented, "click on the page Business League Customer "icon, and we will be happy to serve you! 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 entering the system, in addition to the process of using moving parts changes in physical and chemical properties of wear 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 hydraulic price to normal operation. 2, the oil pump drive shaft seal should well to pay attention to where the seals should be replaced using the "lips" genuine seal, can not use the "single-lip" seal instead of custom hydraulic cylinders, because "single lip" only one-way seal oil seal do not have the gas sealing function. Hydraulic pump consecutive "cavitation" noise, such as elevated oil tank automatic fault manufacturer of hydraulic cylinders, hydraulic pumps repair process through inquiry, discovery is the hydraulic pump drive shaft seal misuse "single lip" seal due to our Texas the largest cylinder manufacturers, as Texas cylinder manufacturers on behalf of our time for users to solve difficult problems, and today we want to analyze the three major reasons for hydraulic cylinders made loud. A relief valve hydraulic instability, such as due to the spool valve hole with improper contact with the valve seat or cone valve is stuck at the dirt, the orifice plug, spring skew or invalidation or stuck in the valve spool hole mobile working, causing the system pressure fluctuations and noise. 2, the valve to adjust properly, so valve spool moves too fast, resulting commutation impact, resulting in noise and vibration. 3, mechanical vibration, such as an elongated pipe, elbow without adding more fixed, in an oil circulation obsolete, especially when higher flow rate, jitter prone pipe; rotating part of the motor and a hydraulic pump are unbalanced, or when mounted for the poor, or loose coupling, etc., can produce vibration and noise.
