Selected model: Jinjie J-1730D
Typical application · Equipment selectionFixed-power drain access points: assess blockage and supply before hose feeding
Jinjie J-1730D
Confirm power, water, pipe and nozzle compatibility before maintaining drains through a fixed access point, reducing unplanned repositioning and repeated trial work without promising one-pass clearance.
01 · What makes this task difficult?
The illustration concerns drain access-point maintenance, not man-entry. Distinguish loose grit and soft deposits from hard obstructions, roots or suspected collapse; more pressure is not a universal remedy.
An outlet exists but suitability is unknown
Have competent personnel verify supply, cables and wet-area protection
Loosened deposits have no discharge route
Check downstream collection before staged assessment
02 · Why consider this Jinjie machine?
At a fixed maintenance point with suitable power, water and accessories, J-1730D can organise drain flushing with an appropriate nozzle, coordinated hose handling and drainage checks.
380 V and site electrical protection
Have competent personnel verify supply, cables and wet-area protection
Establish infrastructure suitability first
Supply, nozzle and wastewater arrangements
Check downstream collection before staged assessment
Avoid loosening deposits without controlling backflow
03 · A better cleaning workflow and customer value
Confirm power, water, pipe and nozzle compatibility before maintaining drains through a fixed access point, reducing unplanned repositioning and repeated trial work without promising one-pass clearance.
Establish infrastructure suitability first
An outlet exists but suitability is unknown · Have competent personnel verify supply, cables and wet-area protection
Avoid loosening deposits without controlling backflow
Loosened deposits have no discharge route · Check downstream collection before staged assessment
Match tools, the material and the working route before comparing labour, time, consumables and maintenance costs. The potential value depends on suitable conditions and correct operation; no fixed saving or damage-free result is promised.
No man-entry or inferred explosion protection is proposed. Hard blockage, collapse and unknown hazardous atmospheres need separate processes. Do not transfer H/HS engine, reel or accessory specifications to the D model.

Site, material and contamination
The illustration concerns drain access-point maintenance, not man-entry. Distinguish loose grit and soft deposits from hard obstructions, roots or suspected collapse; more pressure is not a universal remedy.
Equipment basis and model differences
Current J-1730D information gives a 380 V electric option; assess 170bar（17MPa） and 30 L/min with material, diameter, bends, nozzle and discharge. These figures guarantee neither reach nor parallel gun capacity, and electric power does not establish hazardous-area suitability.
| Site problem | Equipment / conditions | Suggested method | Potential value |
|---|---|---|---|
| An outlet exists but suitability is unknown | 380 V and site electrical protection | Have competent personnel verify supply, cables and wet-area protection | Establish infrastructure suitability first |
| Loosened deposits have no discharge route | Supply, nozzle and wastewater arrangements | Check downstream collection before staged assessment | Avoid loosening deposits without controlling backflow |
Working method, accessories and site supply
- Record pipe size, material, length, bends and fault locations; isolate access and traffic.
- Trained personnel verify nozzle, hose, power and water against instructions, not the illustration.
- Stop and reassess resistance, backflow, leaks or suspected damage; inspect restoration after collection.
Limits and safety
No man-entry or inferred explosion protection is proposed. Hard blockage, collapse and unknown hazardous atmospheres need separate processes. Do not transfer H/HS engine, reel or accessory specifications to the D model.
Questions for this task
Prepare site information
Provide pipe records, blockage details, access points, power and water/wastewater conditions.
FAQ
Is a 380 V supply alone sufficient?
No. Verify capacity, protection, wet-area conditions, cables and instructions.
Does 170bar（17MPa） determine jetting reach?
No. Diameter, bends, nozzle, blockage and downstream conditions all matter.
What site information is needed for selection?
Provide pipe records, blockage details, access points, power and water/wastewater conditions.
Select equipment for the actual site
Provide pipe records, blockage details, access points, power and water/wastewater conditions.
