Performance parameters of hydraulic pump of hydraulic press




Performance parameters of hydraulic pump of hydraulic press




(1) The working pressure of the hydraulic press The working pressure of the hydraulic pump refers to the output pressure during the working of the machine:

(2) Rated pressure The rated pressure of the hydraulic pump refers to the maximum working pressure that the hydraulic pump can achieve during continuous operation according to standard conditions. Exceeding this value is overload.

In addition, there is the maximum allowable pressure, which is the limit pressure allowed by the hydraulic pump to be overloaded in a short period of time. It is affected by many factors such as the sealing performance of the hydraulic pump itself and the strength of the parts.

(3) Displacement The displacement g of the hydraulic pump is the volume of oil that can be output by the shaft after one revolution without considering the leakage.

(4) Theoretical flow of hydraulic press The theoretical flow of hydraulic pump refers to the oil volume y that can be output per unit time without considering leakage. If the rotational speed per minute of the hydraulic pump is n, the theoretical flow per minute of the hydraulic pump is Q. = lVn.

(5) The actual flow between the hydraulic presses is the output flow of the hydraulic pump when it is working. The flow of the hydraulic press at this time takes into account the leakage of the hydraulic pump, so the actual flow is less than the theoretical flow.
