Grab the quantitative pump system at boot time, the spool valve block which will take a long time to respond, so start at the moment the pressure is very high, sometimes even more than the pipe burst pressure, open and closed by reversing motor control grab, the instantaneous pressure frequently generated is prone to burst pipes the problem, then we should be how to solve?
Technical solutions to the problem:
The design of the grab hydraulic system of Shanghai Machinery Co., Ltd adopts valve control, the motor always rotates in one direction, the hydraulic pump is changed from the original quantitative pump to the variable pump, and the system adopts servo technology. Please refer to the most advanced electric hydraulic grab in china.
Advantages of technical solutions:
1., low failure rate
2. high efficiency
3. save energy
4. high grasping force
5., convenient maintenance
6., simple maintenance
7., the load on the grid is small
8., the protection of electrical components
9. hydraulic system instantaneous pressure small impact, not easy burst pipe.
Electric hydraulic grab, visual test, condition:
1. grab oil temperature is less than the working environment oil temperature plus 20o.
2. grab within two meters, the noise is less than 70 decibels.
In the use of grab when such problems occur, we need to calmly face, do not blindly repair, should be good at using experience to deal with, but also be good at taking notes, for the next issue of rainy days.
