XINLAN teaches you how to correctly install the coupling on the oil pump

The following is XINLANCouplingCo., Ltd. analyzes how to install on the oil pump
Coupling:
(XNUMX) Preparations for the commissioning test bench
1. Check the coupling
If the coupling of the output spindle has been removed, when installing the coupling, a dial gauge must be used to adjust it to ensure that it is coaxial with the output shaft. Note that the coaxiality is required to be 0.05mm.If the axis is different, it will cause vibration.
2. Check whether the protective cover has been fixed.
3. Clamp the high-pressure oil pump.
Use the random clamping attachments to reliably clamp the high-pressure fuel injection pump to the working table of the test bench, and connect it with the main shaft coupling, and then connect the oil pipe between the test bench and the oil pump.If the fuel injection pump used is a distribution pump, you need to connect the 12V/24V power jack to the solenoid valve coil of the distribution pump, and use the toggle switch to select the appropriate voltage.
4. Inject test oil
Open the side doors on both sides of the lower part of the test bench.Pay attention to the oil level indicator tube, and do not allow oil to flow out of the tube.Pull out the fuel tank and pour 60 liters of test oil into the fuel tank.
5. Connect the power cord
Ensure that the main power switch on the lower door of the test bench is in the "O" position, open the lower rear door, and introduce the unpowered three-phase four-wire cable with the appropriate capacity from the bottom hole of the test bench to the distribution board.If you have a good ground wire, please introduce the ground wire together.Please find the five unwired R, S, T, O, G or (ground) terminals at the bottom of the right terminal.Note that the O and G (or ground) terminals have been short-circuited when the product leaves the factory. If you have a good ground wire, please remove the short wire and connect the incoming ground wire to the G (or ground) terminal reliably. The neutral wire of the phase four-wire can be connected to the O terminal; users who do not have a good ground wire, do not remove the short wiring, please directly connect the imported three-phase four-wire neutral wire to the O terminal reliably.Connect the three phase wires of the three-phase four-wire to the R, S, and T three terminals (one terminal is connected to one phase wire) in order to ensure that there is no short circuit connection.Close the back door.
(XNUMX) Power-on debugging test bench host
Connect the other end of the three-phase four-wire cable (with three-phase four-wire plug) to the power grid through the automatic protection switch, and close the automatic protection switch to send power to the test bench.
1. Spindle rotation selection
According to the rotation direction of the mounted fuel injection pump, select the appropriate rotation direction on the spindle rotation selection switch on both sides of the test bench (L is left-handed, R is right-handed).
2. Power-on observation
Set the main power switch on the back door to "1". At this time, the test bench is energized and the digital tube on the meter lights up, indicating that the system has entered the working state.
3. Debugging of oil circuit system
Press the start button of the fuel pump motor on the instrument, and the light only glows, that is, the fuel pump motor starts to work. At this time, pay attention to whether the rotation direction of the fuel pump motor is consistent with the direction marked on the fuel supply pump, press the stop button of the fuel pump motor, and then Turn off the main power switch at the rear of the test bench (set to the "O" position), and disconnect the three-phase four-wire cable that supplies power to the test bench from the grid (ie, disconnect the automatic protection switch).Then open the electric control door at the lower part of the test bench, find the three terminals R, S, and T that are connected to the three phase wires, connect any two of the phase wires exchange terminals (namely commutation), and connect them reliably to ensure that there is no Short-circuit connection.Close the electric control door, and then repeat the work of 1, 2, and 3.In this way, the rotation direction of the fuel pump motor is consistent with the direction marked on the fuel supply pump.Locate the fuel regulating valve in the middle of the front panel of the test bench, turn it clockwise, the low pressure gauge will indicate low fuel pressure, turn counterclockwise, and the high pressure gauge will indicate high fuel pressure (the oil return joint should be blocked).
