Diesel pile driver with group type electric control oil supply pump
The diesel pile driver is characterized in that an oil supply pump assembly and an electric control unit are installed on a piston of the diesel pile driver, the oil supply pump assembly at least comprises two oil supply pump units, all the oil supply pump units are connected in parallel and then lead to an oil nozzle assembly, and each oil supply pump unit comprises a pump body; a plunger is arranged in a plunger cavity of the pump body in a sliding mode. A high-pressure oil way and a low-pressure oil way are further arranged on the pump body, a valve element arranged on the pump body is located at the intersection of the high-pressure oil way and the low-pressure oil way, and the valve element is connected with the electromagnet through a valve rod; a first position sensor and a second position sensor are arranged at the corresponding positions of the piston, and the first position sensor, the second position sensor and the electromagnet are electrically connected with the electric control unit. According to the diesel pile driver, the oil injection pulse width can be flexibly controlled, the oil injection timing can be flexibly adjusted, high-pressure diesel is injected into the air cylinder at the optimal moment, and the maximum oil supply amount can be adjusted by increasing or reducing the actual working number of oil pumps in the oil pump set.
本发明公开了一种具有组式电控供油泵的柴油打桩机，其活塞上安装有供油泵组件和电控单元，供油泵组件至少包括有二个供油泵单元，各供油泵单元相互并接后通向喷油嘴组件，每一供油泵单元均包括有泵体，在泵体的柱塞腔中滑动设置有柱塞；在泵体上还设置有高压油路和低压油路，设置于泵体上的阀芯位于高压油路和低压油路相交处，该阀芯通过阀杆与电磁铁相连接；活塞的对应位置设置有位置传感器一和位置传感器二，所述位置传感器一、位置传感器二和电磁铁与所述电控单元相电连接。该柴油打桩机，不仅能够灵活控制喷油脉宽和调整喷油正时，使得高压柴油在最优时刻喷入气缸，而且可以通过增加或者减少油泵组中油泵实际工作数量来调整最大供油量。
