Features a diesel pump

1. Automatic start: diesel pump unit receiving fire / pipeline pressure / blackout / or other start signal within 15 seconds to automatically start and put into operation at full load
2. Automatic Charge: battery available charge electricity or diesel motor automatically charged to ensure the smooth starting unit
3. Automatic alarm: diesel engine low oil pressure, high temperature, such as failure alarm protection, alarm and shutdown when speeding
4. Automatic preheat: diesel engine in a hot standby machine to ensure that emergency work
5. Direct Connect: 360kw diesel pump unit following the country's first use of diesel and pump through elastic coupling direct connection technology, reducing points of failure, and the starting time of the unit is shortened, increasing the reliability and performance of the emergency unit
6. The user can also set additional requirements for alarm output
7. With telemetry, remote, remote control function

Ordinary diesel engine camshaft is driven by means

Ordinary diesel engine camshaft is driven by means of high-pressure pump diesel fuel delivered to each cylinder chamber. This approach to oil changes with the engine speed changes, the optimum amount of oil can not do all kinds of speed. And now more and more widely used in electronic control common rail diesel injection system can better solve this problem. Common rail injection fuel system from the high-pressure pump, public automatic fuel dispenser supply tubing, fuel injectors, electronic control unit (ECU) and a number of pipeline pressure sensors, the system each injector through their high-pressure tubing and public supply tube connected to the public for the pipeline for injector has played the role of hydraulic accumulator. When working, high-pressure pump to the high pressure fuel delivery to the public for the pipeline, high pressure pumps, pressure sensors and ECU composed of closed-loop operation.
