Product description
The hydraulic press relief valve is a control valve that primarily functions in constant pressure overflow, pressure stabilization, system unloading, and equipment safety maintenance. Constant pressure overflow effect: In a constant pressure pump energy-saving regulation system, the constant pressure pump provides a stable flow rate. When the system pressure increases, the flow rate demand will decrease. At this time, the hydraulic press relief valve opens, allowing excess flow to overflow back to the oil tank, ensuring the inlet pressure of the hydraulic press relief valve, i.e., the stable pump outlet pressure (the valve port often opens with pressure fluctuations).
Hydraulic press relief valves generally have two structures: 1. Direct-acting hydraulic press relief valve 2. Pilot-operated hydraulic press relief valve.
The main requirements for hydraulic press relief valves are: large pressure adjustment range, small pressure adjustment error, small pressure fluctuation, sensitive action, large overload capacity, and low noise.
Hydraulic presses directly driven by oil pumps have the following characteristics:
1. The travel speed of the hydraulic press moving crossbeam depends on the pump's liquid supply and is unrelated to the deformation resistance of the workpiece during processing. If the pump's liquid supply is constant, the operating speed of the hydraulic press is a fixed value.
2. The power consumed by the pump is related to the deformation resistance of the workpiece being processed. The greater the operating deformation resistance, the greater the power consumed by the pump, and vice versa.
3. The uniform movement of the moving crossbeam and the change in the pump's supply force can be used as signals for the operating distributor to complete the automatic control of the hydraulic press.
4. Low investment, small footprint, and simple daily maintenance. The pump in the pump direct drive system is selected according to the larger operating speed and pressure of the hydraulic press, but when the hydraulic press is in the filling stroke, return stroke, auxiliary process, and short-term required working pressure, the pump is not fully utilized, especially for large-tonnage hydraulic presses, its utilization coefficient is very low. Therefore, hydraulic presses tend to use staged drive operation speed and pressure.
