Today, the editor will introduce to you the main faults and their causes of the speed control system of the small Hydraulic Press:
- 1. Small hydraulic machine actuator hydraulic cylinder, hydraulic motor) the main reason for no small feed:
- 2. The pressure reducing valve in the speed control valve is stuck, causing the pressure difference before and after the throttle valve to change with the external load. It is often seen that the minimum feed is increased due to the small load when the feed is small.
- 3. The spring of the speed control valve fixed differential pressure reducing valve is too soft, so that the pressure difference between the front and rear of the throttle valve is too low, and the small flow through the speed control valve is unstable.
- 4. The orifice of the throttle valve of the small hydraulic machine is blocked, resulting in no small flow or small flow instability.
The above content is how to solve the failure of the small hydraulic press, I hope it can be helpful to everyone. If you want to know more about hydraulic press, please call Dongguan China Machinery Co., Ltd. We will serve you wholeheartedly.
