What are the performance requirements of the speed regulating valve in the four-column hydraulic press?
1. The pressure difference between the inlet and outlet of the oil chamber refers to the full throttle opening, when the nominal flow rate is passed, the pressure difference between the valve inlet and outlet oil chamber is generally about 1mpa. If the pressure difference is too low, the pressure reducing valve part cannot perform pressure compensation on the throttle valve, thus affecting the stability of the flow.
3. Steady flow refers to the flow at which the speed control valve can work normally, that is, the change rate of the flow is not more than 10%, and there is no flow cutoff. The stable flow of QF type speed control valve and QDF type one-way throttle valve is generally about 10% of the nominal flow.
4. Internal leakage is the flow from the oil inlet chamber to the oil outlet chamber from the matching gap between the valve core and the valve body when the throttle valve is fully closed and the pressure of the oil inlet chamber is adjusted to the nominal pressure, and the internal leakage is required to be small. . In addition, the four-column hydraulic press requires that the speed control valve is not easy to be blocked. Flow through the valve is less affected by temperature.
mechanical power press is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.

2. The flow adjustment range, in general, the larger the flow adjustment range of the four-column hydraulic press, the better, and when adjusting, the flow changes evenly and the adjustment performance is good.
