| Field or task | Configuration that requires attention | J-3522D Selection Judgment |
|---|---|---|
| Heavy soiling work station for industrial use | Trial washing and isolation; match pressure, flow, and working attachment | Test the cleaning with materials, dirt, and site conditions, and do not rely on the maximum pressure promise for cleaning effectiveness. |
| Outer appearance of the device | Sensitive areas; pressure, flow, and working attachment matching. | Test the cleaning with materials, dirt, and site conditions, and do not rely on the maximum pressure promise for cleaning effectiveness. |
| Factory hard-surfaced areas | Water supply and drainage; pressure, flow rate, and working attachment matching. | Test the cleaning with materials, dirt, and site conditions, and do not rely on the maximum pressure promise for cleaning effectiveness. |
| More loose dirt areas | Waste collection method; pressure, flow, and tool compatibility | Test the cleaning with materials, dirt, and site conditions, and do not rely on the maximum pressure promise for cleaning effectiveness. |
Before selection, it is recommended to confirm the following four items:
- Identify the surface, the soil and any sensitive parts or areas that must stay dry.
- Available power, distribution conditions, and job protection.
- Continuous water source, job distance, and wastewater discharge direction.
- Daily tasks, pipe gun attachments, and usage and maintenance conditions.
Industrial heavy-soil tasks
Which industrial heavy-soil tasks should be assessed?
These tasks do not establish multi-lance capability. First assess adhesion, material tolerance, nozzles, pressure, distance, water/wastewater and protection.
Address oil, oily sludge and deposits on equipment, parts and metal workpieces.
Check material tolerance, nozzle distance and wastewater conditions before purchase.
Flush residual casting sand, sediment, scale, surface rust and loose rust layers.
Complete rust removal or replacement of abrasive blasting is not promised; assess results against adhesion.
Clean scale, grease, resin and deposits from equipment exteriors, subject to assessment.
Confirm isolation, cleaning access, water and wastewater collection first.
Flush sediment, grease, cement or asphalt residue from construction vehicles and equipment, subject to material and adhesion checks.
For assessed heavy-soil maintenance with appropriate working distance and operator protection.

Operating principle
The operation process of J-3522D is divided into four steps.
This is a function flow description and is not intended as the internal water circuit cross-section or component location diagram.
01 Water supply preparation
First, check the water source, inlet conditions, and sustainable water supply.
02 drive and pressure generation
The motor drives the pump operation, and the operating conditions should be checked against the specifications of this machine.
03 Pressure adjustment and piping
Organized by matching piping and working attachment for flushing, no assumption of valve setting.
04 jetting and collection
Arrange the work method according to the material, isolate splashing and collect the wastewater.
Professional selection
Pressure, flow rate, and site conditions should be considered together.
Do not take the maximum value as the continuous operating value, and do not take the theoretical hydraulic power as the rated power.
Pressure and flow rate
Working pressure, maximum pressure, and adjustable range are different for different diameters; they should be verified separately based on the original settings of this model and actual operating conditions.
Power and Environment
Check the power supply and protection according to the voltage, power, and random instructions; the presence of power does not mean that any line is applicable.
Water supply and working attachment
Continuous water supply, pipeline pressure resistance, and nozzle need to be matched; do not derive multi-gun capability or fixed area efficiency based on the entire machine's flow rate.
Construction details
Motor, pump, inlet and outlet connections
Through the overall view of the machine, understand the structure of the J-3522D host, the long brush, the high-pressure hose, and the water inlet connection, which facilitates communication of the configuration with your tasks.
Motor / pump / lance
Check electric drive, pump, gauge and lance
Inspect the motor, pump, gauge and lance arrangement; configuration follows current sales documentation.
Inlet / outlet / lance and hose
Check water connection and lance pressure hose
Before purchase, check inlet/outlet, hose length, supply conditions and site drainage.
Operating cost
Equipment usage cost, how should it be calculated?
When there are no actual data on human resources, energy, and maintenance, the energy saving ratio is not publicized.
Procurement and supporting investment
Record the entire machine, the hose attachment, the on-site water supply, and the power supply configuration.
Operating costs
Record the actual labor hours, water, and electricity costs, taking into account the collection and discharge of waste.
Consumables and maintenance
Record piping, nozzle, sealing, and power maintenance according to this model's instructions, without estimating uniformly
Total operating cost＝purchase and accessories＋labor during usage period＋water and electricity or fuel＋consumables maintenance＋waste disposal.
When comparing, use the same task, usage duration, and cost range; separate the equipment investment from daily expenses.
MAINTENANCE
Include inspection and maintenance in each task.
Before maintenance, check the user manual for this machine to confirm the type of oil, maintenance schedule, and operating procedures; if there are any unclear points, bring the model number and usage conditions to consult after-sales service.
Water supply and connection
Check the water intake requirements and visible connections according to the instructions, and record any leaks, loosening, or abnormalities.

— FAQ
You may also be interested in J-3522D
Make judgment based on the tasks, configuration, and usage conditions of this model.
Can 22 L/min directly prove cleaning efficiency?
No. Flow is the volume of water delivered per unit time. Measure the area cleaned and the time taken under representative conditions, including the surface, soil, nozzle, supply and operator technique.
Is it suitable for cleaning concrete or paint residue?
First, obtain the materials, surface standards, and test washing conditions, and do not directly use the existing scene names as the promise of cleaning effects.
What should be verified first when comparing with J-5022D?
First, distinguish each unit's working condition and maximum pressure record, then verify the flow rate, power supply, pump operating condition, and protection configuration.
Why is it necessary to check for drainage in industrial fixed positions?
The wastewater and water discharged should be collected and treated in time. The drainage conditions will affect the continuous operation schedule, and it cannot be solely based on the equipment parameters.
What documents should be provided during selection?
Cleaning object, surface material, dirt, no-water areas, working distance, water supply and drainage conditions. For electric solutions, check the on-site power supply.
How to confirm standard and optional configurations?
Verify each item on the order and delivery list. The long brush, angle nozzle, and base hose are separate from the additional hose length, rotating head, and floor scrubber, and are not determined by the image.
Where should daily maintenance start?
Retain the J-3522D name plate, configuration sheet, and random instructions. Check power supply and protection, inlet water, piping, and spray gun. Oils, cycles, and disassembly are according to the machine's instructions. The website does not provide its own cycle.
What should be done if there is abnormal water discharge or pressure?
Follow the random instructions of J-3522D for shutdown processing, record the water source, fittings, pipelines, and abnormal phenomena, then contact after-sales. Do not disassemble the pipe under pressure, and do not modify the pressure regulating or protection components according to the web image.
Tell us the cleaning object, the dirt, and the water supply conditions, and together see how the J-3522D is configured.
