Technical parameters: High rated pressure: 63MPa high-pressure rated Displacement: 2.3ml / second low pressure rated pressure: 1MPa Low Rated Displacement: 12.5ml / sub-maximal hand force: ≤500N Weight: 10Kg Dimensions (mm): 650 × 140 × 140 oil storage: 3L manual hydraulic jack Why is there noise it? Manual hydraulic jack widely used in all walks of life. With the increase of applications, many questions about the manual hydraulic jack also crop up in the course will be issued a manual hydraulic jack unusual noise, affecting the normal work. 1, air enters the hydraulic system is the main reason for noise; 2, mechanical vibration manual pump, such as an elongated tubing, no more than plus fixed elbow, in an oil circulation obsolete, especially when higher flow rates when prone to shake the tube so noisy. Rotating part of the motor and the pump does not maintain a balance, or at the time of the installation is not good, or loose coupling, these are likely to produce vibration and noise; 3, relief unstable syb1 type manual pump, for example, Because of the slide valve and the valve hole with improper contact with the valve seat or cone valve is stuck at the dirt clogging the orifice, such as the failure of the spring or skew the spool valve hole stuck or moving ineffective manual pump prices, causing the system pressure fluctuations and noise; 4, valve improperly adjusted, so that the spool valve to move too fast, resulting commutation impact, resulting in more noise and vibration is a manual hydraulic jack cylinder occurs because the noise syb2 hand pumps in use. if you find your manual hydraulic jack appears sound, check as soon as possible to ensure the normal use.
