Efficient energy-saving brushless diesel pump

Abstract

The invention discloses an efficient energy-saving brushless diesel pump which comprises a shell, a brushless motor assembly, a controller, a filtering device, an oil inlet volume detecting device and a flow controlling device. The flow controlling device is composed of an oil spray volume detector and a voltage regulator, wherein the oil spray volume detector and the voltage regulator are electrically connected with the controller; the oil spray volume detector is arranged inside an oil spray nozzle of a diesel engine; the voltage regulator is arranged inside a controller seat. The intermittent work time of the diesel pump can be set through a timing controller, and the working efficiency and energy-saving effect of a product are improved; voltage-variable oil supply can be set through the flow controlling device according to the required oil supply volume, the power waste of a motor is avoided, and the diesel pump saves more energy and is more economical; the oil inlet volume detecting device detects whether oil exists in an oil tank or not, a pump body can be prevented from idling, and the service life is prolonged; the oil can be preheated through a heating device; meanwhile, the diesel pump is compact in structure and is driven through the brushless motor, noise is low, and the service life of the product is greatly prolonged.

Description

technical field [0001] The invention relates to a diesel injection device, in particular to a high-efficiency energy-saving brushless diesel pump. Background technique [0002] The diesel pump sucks the diesel oil from the diesel tank, pressurizes it and delivers it to the fuel delivery pipe to ensure continuous fuel supply to the fuel injector. It cannot be sucked out by a diesel pump; the oil pump in the prior art usually adopts a double-roller structure, which is not compact enough, which makes the entire oil pump motor load too large and reduces the effective output power of the motor, and the oil pump with this type of structure When the oil tank is empty, the technician cannot stop the oil suction operation, which will easily cause the pump body to turn dry and burn out; secondly, the oil supply volume of the oil pump in the prior art is constant, and when a large amount of oil supply is not needed, it passes through the pressure relief valve Drain oil, thereby causin...
