Смещение: 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.
Номинальное давление: It is the pressure value at which the pump can work stably for a long time. В целом, 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.
Максимальное давление: 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. Обычно, it is slightly higher than the rated pressure, например, 35 – 40МПа.
Скорость: The rated speed is the optimal rotational speed of the hydraulic pump under the designed working conditions. В целом, it matches the rotational speed of the engine, and it may be around 1500 – 2000об/мин. 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.
Объемный КПД: It reflects the ratio of the actual output flow rate to the theoretical flow rate of the hydraulic pump. В целом, it is relatively high, usually above 90%, which reflects the flow output capacity of the pump and the internal leakage situation.
