1. The pump should be installed on a flat base less than 15 degrees
to ensure the best lubrication conditions
2. Confirm the inlet size of the high-pressure pump piping. The
inlet pipe diameter should be 1.5-2 times the inlet size of the
pump. The inlet and outlet of the pump must be equipped with hoses
to avoid pressure and fluctuations generated by the system. It is
best to install accumulators to avoid bending of pipes.
3. The water supply pressure should be 1.5-8kg / cm2. The water
supply temperature is below 70 degrees. The water supply system of
the high-pressure pump must avoid the entry of air to ensure that
the pump parts are not damaged.
Direction of rotation: The direction of rotation of the
high-pressure pump is the direction in which the top of the pulley
must face the pump head.
4. Before starting the motor-pump system, the following must be
done
1). Check whether the crankcase lubricating oil is normal. If the
oil level indicator of the gear box has only one engraved line, the
oil level cannot be lower than the engraved line, but not higher
than the engraved line 5mm. If the oil level indicator of the gear
box has two Each line, the oil level is between the two lines.
2) Confirm that the valves of all pipes have been opened, and the
medium can flow into the inlet of the pump and exhaust the air
inside the system.
3) The operation of the high-pressure pump is not allowed to exceed
the specified pressure, flow and speed.
4) Before spraying, the high-pressure nozzle should confirm whether
the spray direction is safe. If there are unsafe factors, they
should be eliminated in time to ensure safe production.
5. In order to remove the water in the pump to facilitate the
placement in the freezing point environment, the pump can run for
no more than 10 seconds under the condition of no water inlet.
6. For the system where the overflow valve is installed, the
overflow pipe must be a hose. The overflow pipe should not be
connected to the water inlet of the pump, but should be connected
to the water tank or sewer.
7. When used for water storage tank, the suction line should use a
hose of less than 3 meters, and the water level should be set
higher than the height of the pump. If the water supply pressure
does not reach the required pressure, it is recommended to use a
booster pump.
8. Clean water should be used for the water supply, and a filter
should be used on the supply line to prevent the inhalation of
foreign objects.
9. Before operating the high-pressure pump, loosen the pressure
regulating valve, and then gradually increase the pressure as
needed after operation.
10. Lubricating oil should use SAE20W-50 or the same level of
lubricating oil.
11. Lubricating oil should be replaced after 50 hours of initial
use, and every 500 hours thereafter.
12. The water inlet filter should be regularly checked and cleaned.
13. All moving parts of the plunger pump must not be in a dry
state.
14. High-pressure pumps are not allowed to use acidic, alkaline or
corrosive liquids.
Troubleshooting
Malfunction | Cause | Solution |
The pump is running but does not absorb water |
problem with the water supply | Open the water supply valve Confirm whether the water supply line is in a folded state Do not allow air to enter the water supply line |
| The pump is running but fails to meet the pressure requirements | Water supply line is blocked Air in the pump One-way valve fails or foreign matter enters Pressure regulating valve malfunctions or foreign matter enters Nozzle failure Seal failure | Check the suction line Check the suction line Wash or replace Wash or replace replace replace |
1. Sudden vibration when the pump is running 2. Unstable pressure / pulsation, no pressure operation | Inhaled air One-way valve fails or foreign matter enters Damaged O-ring at the lower end of the check valve Check valve damaged overall Component wear The inlet pipe is blocked and the water intake is blocked Idling Accumulator without pressure | Check the suction line Clean safety valve and replace Replace O-ring Replace check valve Replace components Check whether the system is clogged and air leaks, the pump inlet
pipe size is appropriate Check whether the inlet pipe is blocked and the size is appropriate Repressurize or replace the accumulator |
| Pressure drop, sudden pressure drop in the pipeline | Seal wear Valve spring broken Worn or damaged nozzle Drain valve blocked Worn or damaged hose Due to throttling, the pump is idling Uninstall | Replace the seal assembly Replace the spring Replace the nozzle Cleaning valve assembly Repair / Replace Check the inlet pipe at the entrance Check if it works |
| Running noise | Bearing wear Idling | Replace the bearing and refuel Check whether the inlet pipe is blocked and the size is appropriate |
| Excessive unloading of overflow saliva | Plunger wear Component / seal wear Too much vacuum Plunger break Inlet pressure is too high | Replace plunger Adjust or replace the seal assembly Reduce the vacuum on the suction side Replace plunger Reduce inlet pressure |
| The crankcase temperature is too high | Wrong choice of lubricant Crankcase oil volume is not suitable | Choose the right lubricant Adjust the oil level to the appropriate amount |
| Crankcase water intake | Humidity is too high Seal wear | Reduce oil seal interval Replace the seal |
