Caterpillar, the world's maker of construction machinery, relies on a real-time positioning system at a heavy equipment factory in Belgium to ensure the correct installation of hydraulic valves and hoses. When workers assemble hydraulic valves at the Caterpillar Belgium factory, they use tweezers to tighten the conduit (made of rubber and steel) to the valve. Valves - Installed on construction vehicles made by Caterpillar - the size of a car engine. To secure the catheter to the valve and to...
After the third reason for the failure of the hydraulic valve - hydraulic shock analysis. 1. Reasons for hydraulic shock The hydraulic system quickly reverses or closes the oil passage, causing the oil flowing in the system to suddenly change direction or stop flowing, causing the pressure to rise sharply, forming a large pressure peak, which is a hydraulic shock. It can be seen that the main cause of hydraulic shock is the sudden start or stop of the hydraulic components. 2, the impact of...
In the above we have analyzed the hydraulic valve cylindrical spool structure, the radial imbalance force acting on the spool causes the spool to become stuck, called "hydraulic clamping." The "hydraulic clamping" in the hydraulic system is the result of the radial imbalance of the spool due to the geometry error of the spool motion pair and the change in the coaxiality. 2, the danger of hydraulic clamping A slight hydraulic clamping increases the frictional resistance when the spool moves,...

The ordinary gear motor has the advantages of simple structure, strong anti-pollution ability and convenient processing, but its structural form makes it inevitably have defects such as radial force imbalance and large output torque pulsation. The compound gear motor is a new type of actuator that combines the internal and external gear motor principle with the wheel train theory. It has the advantages of large displacement, good torque uniformity, low noise, and balanced radial pressure. The...
The electronic gear ratio of the servo motor is to enlarge or reduce the pulse frequency received by the servo to the upper computer. One of the parameters is the numerator and the other is the denominator. For example, if the numerator is larger than the denominator, it is enlarged. For example, if the upper computer input frequency is 100HZ, the electronic gear ratio is set to 1 and the denominator is set to 2, the actual servo running speed is performed according to the 50HZ pulse. The input...
