The invention discloses a rapid water filling
system for a
hydraulic press. The rapid water filling
system comprises a hydraulic driving
system, a water supplementing system and a water-filling and air-exhausting system, wherein the hydraulic driving system comprises a hydraulic oil source, a
hydraulic control valve and a
hydraulic cylinder; the water supplementing system comprises a water pump, afilter, a first
check valve, a first pneumatic control valve, a high-level water tank and a second
check valve; and the water-filling and air-exhausting system comprises a water filling tank, a pressure
relay, a second pneumatic control valve, a third
check valve, a
water column dispersion plate and a third pneumatic control valve. In addition, the invention also discloses a control method for the rapid water filling system of the
hydraulic press. The rapid water filling system provided by the invention has large water filling capacity and rapid air exhausting speed, greatly shortens the timeof water filling, and greatly improves the production
rhythm of the
hydraulic press; the rapid water filling system provided by the invention is driven by the
hydraulic cylinder for water filling, soparameters like the flow rate and pressure of water filling are more stable and controllable; and the rapid water filling system provided by the invention adopts a PLC fully-
automatic control hydraulic press to complete the process of rapid water filling, is simple in operation and convenient in maintenance, reduces the labor intensity of a worker, and increases production efficiency.
