FAQs for High-Pressure Cleaner Users
During the use of high-pressure cleaners, users often encounter issues related to operation, maintenance, and equipment selection. This article compiles frequently asked questions and provides answers to help you better understand key aspects such as daily maintenance of high-pressure cleaners and selection of cleaner nozzles, thereby improving equipment efficiency and lifespan.
Q1: How to extend the service life of the high-pressure pump?
A: Regularly check the lubricating oil level (recommended once a month) and avoid idling. After use, drain all water from the pump to prevent rusting. If the pump is to be out of service for a long time, it is advisable to disassemble it and apply anti-rust oil.
Q2: What should I do if the cleaner has insufficient water pressure?
A: Possible causes and solutions:
Clogged nozzle: Remove and clean it or replace it with a dedicated cleaner nozzle.
Dirty inlet filter screen: Clean the filter screen regularly.
Damaged high-pressure hose: Inspect and replace with a high-pressure resistant hose.
Q3: How to choose a nozzle according to the scenario?
A: The selection of cleaner nozzles should match the cleaning target:
Fan nozzles: Suitable for large-area washing (such as walls, floors).
Rotary nozzles: Effective for stubborn dirt (such as oil stains, rust spots).
Zero-degree nozzles: Used for precise high-pressure cutting (such as cleaning concrete surfaces).
Q4: How to prevent the equipment from freezing in winter?
A: It is recommended to use an anti-freeze high-pressure cleaner, or in low-temperature environments:
Add anti-freeze to the water tank.
Completely drain water from the hoses and pump after each use.
Store the equipment in an environment above 5°C.
Q5: Do high-pressure cleaners consume a lot of water? How to optimize water usage?
A: Ordinary models have a flow rate of about 10-20L/min. Water consumption can be optimized in the following ways:
Choose models with variable frequency motors to adjust the flow as needed.
Use water-saving nozzles to improve water pressure utilization.
Adopt a circulating water system to reuse wastewater.
Q6: Which scenarios are mobile devices suitable for?
A: Mobile high-pressure cleaning equipment, featuring universal wheels and a compact body, is suitable for:
Outdoor construction sites without fixed power sources.
Cleaning mobile targets such as vehicles and ships.
Working in narrow spaces (such as workshop corners, equipment interlayers).
Q7: How to select and maintain high-pressure hoses?
A: When selecting high-pressure hoses, pay attention to:
Pressure resistance: It should be 20% higher than the maximum working pressure of the equipment.
Material: Rubber + steel wire braided layer for wear resistance.
Length: Generally not exceeding 15 meters to avoid pressure loss.
For maintenance, avoid excessive bending and regularly check the tightness of the joints.
Q8: What norms should be followed during operation?
A: Abide by the cleaner operating procedures:
Wear protective gloves and goggles.
Do not spray high-pressure water at people or electrical equipment.
Stop the equipment immediately for inspection if there are abnormalities (such as abnormal noise, oil leakage).
