Everyone should know that the working speed of a 1000-ton hydraulic press is determined by the flow rate. The power of the pump is proportional to the product of the working pressure and the flow rate. When the hydraulic press enters, the equipment load increases and the working pressure increases. Therefore, it is ensured that the hydraulic pump will not be overloaded, reducing the liquid flow and reducing the machine speed.
2.1000 tonsThe running speed of the hydraulic press is determined by the amount of work flow. The power of the hydraulic pump is proportional to the product of the working pressure and the flow rate, that is, the pump power = P * Q. When the hydraulic press returns, the hydraulic press load is small and the working pressure is low. Therefore, the flow rate can be increased without exceeding the output power of the hydraulic pump, that is, the running speed of the hydraulic press is increased.
3. When1000 tonsWhen the hydraulic press is working, the hydraulic press has a large load and high working pressure, so to ensure that the hydraulic pump is not overloaded, the flow rate needs to be reduced, that is, the working speed of the hydraulic press is reduced. In short, to ensure that the hydraulic pump (load pump motor) is not overloaded, high pressure when low flow, low pressure can be high flow, and the running speed of the hydraulic press is only related to the flow, that is, large flow, fast speed, small flow and slow speed.
4. When the machine returns, the hydraulic compressor has a low load and low working pressure, which can increase the working flow while ensuring that the output power of the hydraulic pump does not exceed. Increase the speed at which the machine works, so when the machine returns, the speed is relatively fast. Therefore, it is ensured that the hydraulic pump (load pump motor) is not overloaded. When the pressure is high, the flow rate should be reduced. When the pressure is low, the flow rate increases.
