Why low vibrations about Brick-shock box

Mud brick making machine vibration force mainly from shock or vibration of motor box, large brick machine main hydraulic motor drive excitation boxes generated vibrations vibration.
If vibration power block is the case, what is the cause of it? If vibration of block making machine is found insufficient, first check the hydraulic oil pumping station was big enough, and after a long time of use, erosion, evaporation of hydraulic oil, hydraulic oil is not enough, will erode oil pump power output, thus vibration of block making machine driven. Second, check soil brick making machine hydraulic motor and vibration connected belt is loose.
Brick-making machine vibration within the two eccentric shafts, vibrations, generated by a hydraulic motor via belt drives eccentric shaft vibration. Brick machine belts are loose, work on skid, unable to generate enough vibrations. Check if block machine loose belt vibration force caused it, mostly as a result of block machine vibration loosening, only fixed block machine screws.
If the above two points through inspection, no problems, you can conclude that brick making machines pumpinghollow brick machine, in which case you'll need to remove hydraulic valve cleaning, and thorough cleaning of hydraulic oil using the oil filter, and hydraulic valve plug so as to avoid the recurrence of incidents.
