• Why does the hydraulic press work slower than the return stroke?

  The working speed of the hydraulic press is significantly slower than the return speed. This is not because it is technically impossible to achieve high speed, but because it is an active design trade-off based on power balance and molding process requirements. The core logic revolves around the inherent constraints of the hydraulic system 'pressure-flow-power' and is combined with the core demands of its industry application scenarios. The following is a detailed analysis from the four dimensions of principle, difference comparison, design consideration and application adaptation: 1. Core principle: 'Power Balance Law' of the hydraulic system The operating speed of the hydraulic machine is directly determined by the flow rate of the hydraulic oil (the greater the flow rate, the faster the actuator is pushed), and the core constraint of the system comes from the power limit of the hydraulic pump. The relationship can be expressed intuitively through the formula: Pump power (P) = Working pressure (p) × Flow (Q) (Note: The formula is a simplified model, the actual system efficiency needs to be considered, but the core logic is the same) The rated power of the hydraulic pump is a fixed value (determined by the motor power), so 'pressure

• Factors affecting return speed of hydraulic cylinder and solution strategies

  The return spring of the reversing valve of the hydraulic press not only has insufficient elasticity, but also has a skew phenomenon, causing the spool of the reversing valve to fail to return to its original position after a power outage. Therefore, the opening of the slide valve is too small, which throttles the oil passing through the reversing valve. The initial movement of the hydraulic cylinder is slow. When the temperature is low, the viscosity of the hydraulic oil is relatively high and the mobility is poor, resulting in the slow movement of the hydraulic cylinder. If the outside temperature is really too low, you can use a heater or corresponding insulation measures to increase the oil temperature at startup. The contamination of the oil should be checked; check whether dirt or colloid deposits are blocking the valve core or valve hole, and check the wear of the valve body. The throttling resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. The control pressure of the hydraulic system of the hydraulic press is too low. The piston rod of the hydraulic press is stuck with the cylinder or the hydraulic cylinder is blocked. The way to cover it is to promptly replace the hydraulic oil with better viscosity and temperature resistance. If the outside temperature

• Hazards of excessive temperature of servo hydraulic press

  Hazards of excessive temperature of servo hydraulic press 1. The temperature of the servo hydraulic press itself is too high, which reduces the viscosity of the oil and the leakage increase, and the efficiency of the system and the capacity base of the pump will be reduced. The oil film of moving parts such as slide valves will become thinner and produces greater friction resistance, resulting in increased wear and affects the inability to operate the machine. 2. The temperature of the equipment is too high, causing it to deform itself. Different moving parts in the hydraulic components have different degrees of thermal expansion, which will cause jamming due to the small gap between them at the same time, thus reducing the working efficiency of the servo hydraulic press. 3. Excessive temperature causes the service life of hydraulic oil to be greatly reduced, blocking the gap between the small holes, causing the pressure valve to not work normally. 4. Excessive temperature rise causes the rubber seal to deform, accelerate the aging degree, and cause leakage. 5. The excessive temperature reduces the air separation pressure of the oil, resulting in a decrease in the working performance of the hydraulic system. Therefore, we must follow the different load requirements of the servo hydraulic press and enter it
