According to the requirements of the oil pump and nozzle industry, our company has designed and developed a generation of diesel engine fuel injection system testing and commissioning equipment 12v--180 190 (special for jichai) 12V series pump combining test bench. The main drive of this product adopts the current frequency conversion speed regulation technology, and the stepless speed regulation range can reach 0-4000rpm. The fuel injection pump test bench has stable speed, large output torque and ultra-low noise. The functions of the test-bed, such as rotating speed, oil measurement and counting, fuel temperature, gas pressure, etc., are all displayed digitally, with clear display, reliable operation and high control accuracy. A prominent feature of this test-bed is that it can simultaneously drive the main and auxiliary oil pumps through the cam box to work at the same time, and real-time detect all working conditions of the 12V180 190 isochronous pump. With multi gear speed preset, the preset speed is fast and high precision, which greatly saves the pump adjustment time and improves the work efficiency.
1、 Main features: the main engine adopts frequency conversion speed regulation, and the speed regulation range is ± 4000 rpm. Four digit digital display is used for oil measurement and counting, spindle speed, gear rod travel and advance angle. The fuel temperature is displayed in three digits. Manual speed regulation and speed multi gear preset. 0-0.25mpa air source output, built-in air pump. It has DC12V and DC24V regulated power output. The main machine is of channel steel frame structure, and the overall structure is compact and stable. The shell adopts electrostatic plastic spraying, and the shell is beautiful. The oil collecting tank can be rotated left and right, and can also be adjusted up and down. The test bench has an emergency brake switch. The frequency converter with control mode has high speed accuracy. The test bench has the protection functions of undervoltage, overvoltage, overheating, overload, etc. The test bench is operated on both sides, which is convenient and flexible. The test bench has ultra-low noise. High mechanical efficiency and energy saving. This test-bed is for the maintenance and testing industry of internal combustion engines in oil fields!
2、 According to the oil pump being debugged, the following items can be debugged by selecting appropriate accessories:
1. Test the fuel supply quantity and uniformity of each cylinder of the fuel injection pump at different speeds.
2. Test the fuel supply starting point and fuel supply interval angle of the fuel injection pump.
3. Check and adjust the working performance of the speed reducer.
4. Test and inspection of pressure compensation performance.
5. Test and adjust the working performance of distribution pump.
6. Performance inspection of cold start device and solenoid valve.
7. Measure the return oil volume of the distribution pump at various speeds.
8. Internal pressure measurement of distribution pump at various speeds.
