Precautions when using a high-pressure cleaning pump
2019-10-10
When using a high-pressure cleaning pump, the following points should be noted:
1. Avoid starting under low voltage as much as possible. To effectively use a high-pressure cleaning pump, you need to choose the correct nozzle. Some high-pressure cleaning pumps are equipped with interchangeable nozzles for various purposes. Low-pressure nozzles allow the unit to draw in detergent, while high-pressure nozzles can spray water at different angles. Choosing the right nozzle will make the cleaning process more efficient.
2. When installing the high-pressure cleaning pump, the cable should be overhead, and the power cord should not be too long. When the equipment is underwater, do not pull the cable forcefully to avoid disconnecting the power cord. Do not submerge the high-pressure cleaning pump in mud, otherwise it will cause poor heat dissipation and burn out the motor windings.
3. When selecting a high-pressure cleaning pump, pay attention to its model, flow rate, and head. If the selected specifications are not appropriate, sufficient water volume cannot be obtained, and the efficiency of the unit cannot be maximized. In addition, the rotation direction of the motor should be clear. Some types of cleaning pumps produce water in both forward and reverse rotation, but the water volume is small and the current is large in reverse rotation. Reverse rotation will damage the motor windings. To prevent electric shock due to leakage when the high-pressure cleaning pump is operating underwater, a ground fault circuit interrupter should be installed.
4. Do not let the high-pressure cleaning pump run for a long time without overload. Do not pump a large amount of sand with water. Be careful when spraying windows, vents, eaves, and walls. High water pressure may knock loose car windows or cause them to break. When cleaning wall panels, point the spray gun rod downwards to reduce the impact force on the lower part of the wall panel and prevent water from dripping. In addition, be careful when cleaning exterior walls. Water may seep from inconspicuous holes at the edges of windows. Check all window frames to prevent seepage.
5. Regularly check the motor of the high-pressure cleaning pump. If cracks are found on the bottom cover, the rubber seal is damaged or fails, etc., it should be replaced or repaired in time to prevent water from entering the machine.
