Four-column hydraulic press driven by motor through a transmission mechanism working organs, adding to pressure on the workpiece processing technology, the transmission mechanism for the belt or gear retarding mechanism, work mechanism is divided into spiral mechanism, crank connecting rod mechanism and the hydraulic cylinder, hydraulic press transmission mechanism not only can complete a variety of ways of complex and composite motion, also can complete large-scale succession of stepless speed regulation, then adjust the pressure in the press should pay attention to what?
1, four column hydraulic press to adjust the pressure matters needing attention
Spare pressure can't higher than the pressure of the pump, unless there is supercharging device of hydraulic press, pump actual pressure depends on the load size, are automatically instead of adjusting, four-column hydraulic press for a given pressure is the biggest pressure of normal task, lower pressure relief valve, throttle valve reversing valve in the closed pump such as export, recuperates the overflow valve, pump outlet pressure rise, until the demand value.
In the four-column hydraulic speed control system, the commonly used speed control loop stepless speed control loop and stepless speed control loop, which according to the speed control method is not the same and can be divided into saving speed control loop and volume speed control loop.
