The primary parts of the YCB circular arc gear oil pump are the shafts, bearing bush, shaft end seal, pump body, pump cover, and gears. The double arc sine curve tooth form is used in the gear manufacturing process. Compared to involute gears, it has a significant benefit because during gear meshing, there is no relative sliding of the tooth profile surfaces. This results in smooth operation, no liquid phenomenon, minimal noise, and a long service life for the tooth surfaces. The gear pump in the design, production, and usage of a new field is made possible by the pump's freedom from the conventional design.
There are numerous details to consider when starting and sealing YCB gear oil pumps. If one of these does not work properly, it may lead to equipment failure. Let's look at the first few things YCB gear pumps need to be aware of while starting.
1. The packing seal, especially PTFE, should be adjusted evenly during the first 15 minutes of the start-up process to allow for initial leakage. Adjust one turn at a time, about 8 times to reduce leakage. If leakage drops suddenly and the stuffing box temperature rises sharply, loosen the nut and start again.
2. Before starting the YCB series gear pump, please open the discharge and suction valves. At the same time, the inlet and outlet valves should be fully open, after the pump is turned on, the outlet valve can be gradually adjusted to the required flow rate to start the pump with zero flow rate, to avoid overloading and burning of the motor during start-up.
3. After briefly starting the motor, make sure the YCB gear pump's rotational direction matches the one indicated on the pump casing.
4. In order to prevent damage to the stator while starting the YCB gear oil pump or using it again after extended storage, you should first fill the delivered liquid with auxiliary tools and rotate the pump shaft a few times. It should be noted that without liquid, gear pumps cannot be started, as this could harm the stator.
5. Once the machine is operating, check that the pressure and vacuum gauge readings match the specifications. Also, listen to the noise and vibration coming from the pump. If any of these readings are odd, stop the machine right away and get it checked.
6. When YCB circular arc gear oil pump stops running, the motor should be switched off first, and the inlet and outlet valves should be closed. If the stopping time is long, the liquid in the pipeline and the pump should be drained to prevent corrosion and winter icing.
7. The switch on the pump outlet valve can be adjusted to modify the flow rate when necessary. Even though a greater amount of power is required to achieve this rise in fluid resistance, it is still possible to adjust the flow rate and make further changes that are appropriate for the features of chemical production. Take caution not to alter the pump's inlet valve opening for control, as this may cause the "cavitation" phenomena, which normally occurs when the pump body is subjected to shock, vibration, noise and low flow rates. In severe circumstances, this might prevent the pump from functioning properly.
