4000 psi pressure washer pump comparison point
In the high-end application level of 4000 psi pressure washer pump, common products on the market are often replaced by cast brass or cheap stainless steel, which is difficult to cope with industrial cleaning or severe thermal expansion and contraction in long-term continuous operation. This pump uses heavy-duty forged brass and precision high-frequency nitrided crankshaft, its strength increased by more than 30%. Through strict dynamic balance test, we have designed reinforced ribs inside the pump body, which effectively reduces the metal fatigue caused by high-frequency vibration, and is superior to competitors in stability. In addition, due to the poor heat dissipation of the crankcase, the traditional high-pressure cleaning pump can easily lead to deterioration of lubricating oil and burning of bearings when the temperature is high or under heavy load. winspan, by optimizing the structure of the crankcase heat sink, the surface heat dissipation area is increased by 15%, combined with the splash type large-capacity oil pan, the working temperature rise of the transmission components is reduced by 8 degrees Celsius. This not only prevents the oxidation of the lubricating oil, but also comprehensively improves the operating life of the whole machine under high load.
The assembly dimension tolerance of the whole machine purchased in batch exceeds the standard
the excessive tolerance of the journal will lead to serious assembly vibration. The winspan is processed by high-precision CNC grinding machine, and the shaft hole fit tolerance is controlled at the extremely micron level to ensure the direct alignment and clearance-free assembly of the whole machine factory.
The valve body is prone to metal cracks under continuous high pressure
the traditional casting pump body is prone to invisible cracks under extreme pressure. winspan the use of special high tonnage heavy forging process, completely eliminate the internal pores, to ensure that the pump body is strong under high pressure without cracking.
Frequent wear and failure of vulnerable seals in valves
failure of valves can cause pressure decay and dripping. winspan through the fine grinding of the surface of the ceramic plunger, with self-lubricating wear-resistant water seal, so that the sealing system can run continuously for ten thousand hours without replacement.
Instructions for using 4000 psi pressure washer pump
Fill and check the lubricating oil
before starting, confirm that the crankcase has been filled with special lubricating oil, and the oil level should be accurately at the center of the red dot of the sight glass. Lack of oil or overload operation will cause damage to the bearing.
Ensure sufficient water intake from the water source
the water intake must reach 1.5 times of the rated flow rate of the pump. Air leakage is strictly prohibited in the pipeline. Insufficient water supply will cause serious cavitation and vibration of the pump body.
It is strictly forbidden to idle under the condition of no water
no water dry friction will cause the ceramic plunger to quickly heat cracking. Please start the power source to pressurize after the water source is connected and the air in the system pipeline is discharged.
Keep the inlet filter net clean
the inlet end must be equipped with a filter with an accuracy of more than 50 meshes, and the fine sediment and other particles in the net must be cleaned regularly to avoid wear of the valve plate and valve seat.
