The hydraulic system has been useless for a long time. After this startup, the vibration is particularly severe and the noise is very loud. I do not know what is the reason?
Conclusion: It may be that the accumulator is placed for a long time, and the nitrogen leakage does not play a role in reducing the pulsation. Check the nitrogen pressure, refill the pressure, or replace the bladder. Noise is caused by too much vibration. Without vibration, it will be eliminated.
The cylinder is not working properly. It can only come out but cannot come back. What is the problem?
Summary: Check whether the other end of the cylinder is out of oil, whether the solenoid valve is reversed, and whether the leakage in the cylinder is particularly serious. Whether the return oil line is blocked by foreign matter.
How is the cylinder starting pressure high to return a responsibility? What's the harm? How to solve it?
The high starting pressure of the cylinder is related to the manufacturing quality of the cylinder (such as piston rod bending, cylinder bending, etc.), seal form and installation. For servo cylinder, high starting pressure will affect its dynamic characteristics. For ordinary cylinders, starting pressure requirements are not as strict as servo cylinders, but not too high. Once the starting pressure is found to be high, it is necessary to carefully retest the size of the cylinder parts and check the installation quality of the seal.
Summary:
1. internal resistance is too large.
2. Mechanical failure of the external execution part.
The starting pressure of the cylinder is related to the design structure of the cylinder. The force area of the contact between the oil port and the piston, such as the size of the oil port, namely the force area of the initial starting of the piston, the starting pressure is high, and the starting pressure of the processing force area chamber (starting pressure chamber) between the oil port and the piston is very small.
What are some good suggestions for hydraulic system cylinder synchronization?
Summary: Add one-way throttle valve on branch road, the price is cheaper. Requirements are relatively high to add a shunt throttle valve, the cost is high, but the effect is better.
Hydraulic system maintenance rate is particularly high, what is the main reason?
The main reason is that the environment is bad, the hydraulic system is a relatively sophisticated equipment, usually to pay more attention to maintenance, good oil quality, to filter when refueling, the system seal is better. To improve all kinds of testing equipment, it is necessary to have professional personnel to record and maintain the system.
Hydraulic cylinder action irregular how to do?
To sum up:
1. It may be that the hydraulic pipeline is mixed with air. It is necessary to find out the part that is mixed with air, and then clean and check, reinstall and replace the auxiliary parts.
2. There is also a serious wear of the cylinder, which needs to be repaired or replaced.
3. solenoid valve reversing irregular, need to check the electric furnace part
4. The amplifier of electro-hydraulic servo and proportional valve fails or is improperly adjusted.
When the first one fails, the second one only starts to work. May I ask what devices are better connected between the two hydraulic stations? The others are well designed, just short of the realization of the connection between the two hydraulic stations
It takes time for the oil pump to start. During the time between the failure of the first hydraulic station and the start of the second hydraulic station to output normal pressure, it needs to maintain its pressure
Summary: Through the pressure relay, the pressure signal can be converted into electrical signal to transmit to the standby pump.
