Why manual hydraulic jack will be noise it? Manual hydraulic jacks are widely used in all walks of life. With the increase of applications, a lot of manual hydraulic jack problem after another, in the course will be issued a manual hydraulic jack abnormal noise, affecting the normal work. 1, the air enters the hydraulic system is the main cause of noise; 2, mechanical vibration, such as tubing slender, did not add much elbow fixed, in the oil circulation outdated, especially when higher flow when prone tube chatter noise appears. The rotating part of the motor and the pump does not maintain a balance, or did not in good, or loose coupling, these are likely to generate vibration and noise during the installation; 3, the relief valve is unstable, for example, due to the slide valve the valve hole with improper or poppet valve and valve seat is stuck at the dirt, damp clogging spring skew or invalidation of the spool valve hole stuck or mobile working, causing the system pressure fluctuations and noise; 4, valve to adjust properly, so that the spool valve to move too fast, resulting commutation impact, resulting in noise and vibration. These are manual hydraulic jack cylinder occurs because of noise sbd20d manual pump, in use, if you find that your manual hydraulic jack appears sound, check as soon as possible to ensure the normal use. syb1 hand pumps, Lu Hydraulic (certified), Ningbo manual pump is provided by the Texas Lu of the hydraulic machinery plant.
