The usage method of the suction pump usually includes the following steps:
Preparation phase
Ensure that the suction pump is placed on a stable surface and connect the adapter and tube to ensure that the connection is secure.
Pre startup check
Check if there is friction or inflexibility in the rotation of the suction pump. For self suction pumps with suspension oil chambers, check the oil level in the suspension oil chamber to see if it is within the specified range. Fully open the inlet valve, open the water injection valve to inject water into the pump, allowing the gas inside the pump to be completely discharged. Close the outlet valve and pressure gauge plug.
start-up
Start the motor, open the pressure gauge plug, check if the pressure gauge pointer is in the correct position, open the vacuum gauge plug, and slowly open the outlet valve. The position of the pressure gauge pointer will change with the size of the outlet valve opening. When the pressure gauge pointer points to the desired position for the working condition, stop adjusting the size of the outlet valve.
apply
Place the suction head at the location where gas extraction is required, start the extraction, and after the extraction is completed, turn off the power switch. First, remove the suction head, then remove the pipe and suction head and clean them thoroughly.
Shutdown
Slowly close the water outlet valve, close the vacuum gauge plug, cut off the power, and finally close the pressure gauge plug. For a series operated self priming pump, the last stage pump should be shut down first when stopping.
It should be noted that during use, the water source should be sufficient and the water flow should be unobstructed to avoid affecting the normal use of the pump. After use, it is necessary to clean the debris and dirt inside the pump to avoid affecting the next use.
