[CN 201821161776.1] Energy Saving and Impact Prevention Pump Outlet Control System of Skin Stretching Hydraulic Press
[CN 201821161776.1] Title of Energy Saving and Anti-impact Pump Outlet Control System of Skin Stretching Hydraulic Press: Application Number of Energy Saving and Anti-impact Pump Outlet Control System of Skin Stretching Hydraulic Press: CN 201821161776.1 Applicant: Tianjin Tianforging Press Co., Ltd. Application Date: 2018-7-18 Patent Type: Utility Model The utility model discloses an energy saving and anti-impact control system of pump outlet of skin stretching hydraulic press, the energy-saving anti-shock pump outlet control system includes a pressure control function plug-in, a control cover plate with a pilot sequence valve function, a control cover plate with an overflow valve function, a superimposed filter, a proportional pressure valve, a pressure sensor, and a pressure measuring device. The energy-saving anti-shock pump outlet control system realizes stepless adjustment of the pump outlet pressure through proportional pressure regulation within the measuring range of the proportional pressure valve. The utility model can ensure stepless adjustable control of the liquid pressure of the energy-saving anti-impact pump outlet control system of the skin stretching hydraulic press, effectively reduce the pressure suppression phenomenon in front of the valve caused by the high-frequency response proportional valve control mechanism, prevent the influence of hydraulic force on the electrical closed-loop control of the skin stretching hydraulic press, reduce energy consumption and system noise, and improve the pressure closed-loop control accuracy of the skin stretching hydraulic press.
