When we use the hydraulic press in the process of some unexpected situation is relatively normal, we do not have to worry too much, many times can take corresponding measures to solve. So when the hydraulic machine synchronous error should be how to solve it? The following article content is the specific reason analysis and solution?

Hydraulic machine synchronous error mainly has the flow of the fixed throttle, the symmetry of the hole, the fixed throttle before and after the oil flow pressure difference, hydraulic force and leakage and other aspects of the reasons, specifically the following points:

The radial clamping force of the valve core of the 1. hydraulic press is large, which leads to the resistance of the valve core. Therefore, to push the valve core to achieve the automatic compensation of the oil pressure difference between the D and E chambers, the force B is large, so that the difference between the oil pressure difference before and after the fixed throttle on the left and right sides is large.

2. the hydraulic machine flow through the synchronous valve is too small, or in and out of the chamber 1, the difference is too low, will make both sides of the orifice before and after the pressure drop. However, the speed synchronization accuracy of the fixed orifice with large pressure difference (large pressure loss> is higher than that of the fixed orifice with small national difference, generally not less than 0.8MPa, and the usage flow rate should not be less than 2% of the nominal flow rate.

3. in the shunt valve and the implementation of the components between the access, and their leakage is large, increasing the loop synchronization error. Generally between the shunt valve and the implementation of components, as far as possible no longer access to other control components, to avoid these control components of the leakage of different or other reasons and increase the loop synchronization error.

In addition, the hydraulic machine synchronous valve vertical installation, will affect the synchronization accuracy due to the weight of the spool, so it should be installed horizontally.

After that, if you still have unclear problems, you should also take corresponding measures to solve them according to the above reasons.
