Desplazamiento: It varies according to different applications and configurations, usually within a certain range to meet the hydraulic requirements of various working devices of the bulldozer.
Presión nominal: It is the pressure value at which the pump can work stably for a long time. Generalmente, it is relatively high to provide sufficient power to drive components such as the blade and dozer blade of the bulldozer to operate. It may be around 20 – 30MPa or even higher.
Presión máxima: It is the maximum pressure that the hydraulic pump can withstand in a short period of time. Exceeding this pressure may cause damage to the pump. Generalmente, it is slightly higher than the rated pressure, Por ejemplo, 35 – 40MPA.
Velocidad: The rated speed is the optimal rotational speed of the hydraulic pump under the designed working conditions. Generalmente, it matches the rotational speed of the engine, and it may be around 1500 – 2000rpm. The maximum speed is the highest rotational speed allowed by the pump. Exceeding this speed may affect the performance and service life of the pump.
Eficiencia volumétrica: It reflects the ratio of the actual output flow rate to the theoretical flow rate of the hydraulic pump. Generalmente, it is relatively high, usually above 90%, which reflects the flow output capacity of the pump and the internal leakage situation.
