Diesel pile hammer and fuel system thereof
The invention discloses a diesel pile hammer and a fuel system thereof, wherein the fuel system comprises a fuel quantity control unit, a fuel pump and at least one nozzle; the fuel pump is respectively communicated with the nozzles through a first fuel channel; the fuel quantity control unit comprises a controller and a fuel quantity control valve; the controller is used for receiving a control signal and adjusting the fuel quantity control valve according to the control signal; and the fuel quantity control valve is used for controlling fuel spraying quantities of the nozzles. The diesel pile hammer prevents the defects of manual adjustment, labor consumption and incapability of realizing continuous adjustment of fuel supply caused by the use of a mechanical fuel system in a traditional diesel pile hammer, and adopts an electric control mode to automatically adjust the fuel quantity control valve according to the received control signal to control the fuel spraying quantities of the nozzles, so that the control of the fuel system is simplified, the control difficulty is reduced, the labor cost is saved, the continuous adjustment of the oil spraying quantities of the nozzles can be realized, and the control of the fuel spraying quantities of the nozzles is more precise.
