- 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.
Product overview
J-5022D: match cleaning tasks to site conditions first
For adherent soil on construction equipment, stations and metal components, distinguish loose sediment, oil and hard deposits first.
Include available water and wastewater collection in selection rather than considering pressure alone.
Provide substrate and soil photos to select nozzles, distance and trial requirements and limit surface-damage risk.

How do these figures apply to your site?
Assess specifications against the site task and conditions, not the figures alone.
Pressure affects local jet impact. Provide substrate, soil and working distance to assess trial-cleaning needs.
Flow affects residue transport. Provide water conditions and wastewater destination to select a configuration.
Provide voltage, connection location and working duration for electrical planning and deployment.
Direct jetting targets local soil. Rotary nozzles and abrasive-feed attachments are optional, subject to project and order.
Review task-specific features, then expand the full specification and compare it against site conditions.

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
The machine has been confirmed to have a standard operating pressure of 50 MPa and an operating flow rate of 22 L/min; this confirmation cannot be applied to other models.
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.

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.

— FAQ
You may also be interested in J-5022D
Make judgment based on the tasks, configuration, and usage conditions of this model.
What is the size of 50 MPa and 22 L/min?
The standard working pressure of the machine is 50 MPa, and the working flow rate is 22 L/min. When selecting attachments and arranging water supply, it is also necessary to combine it with the allowable operating conditions of the pump.
Can 22 kW be equivalent to hydraulic power?
No. The rated power of the motor is not the same as the ideal hydraulic calculation. Actual matching requires reference to pump operating conditions and losses.
What should I verify about the AR pump and PA valve?
The specific model of the pump, the allowable operating conditions, and the set pressure of the safety valve still need to be retained in the original version, and should not be inferred from the brand or image.
How to choose between J-5022H?
Fixed industrial power supply and outdoor gasoline transfer belong to different site conditions; separately verify the power, water supply, safety, and delivery versions.
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-5022D 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-5022D 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.
Recommended equipment: sweeper, floor scrubber, squeegee, dust mop, filter cleaning, hopper, pipe jetter, feed and retrieve the hose, filter element, clear width, Jinjie, wanshenglong.
