Miaoliang ML31800 ultrasonic cleaner

The official site has two entries dated 11 March 2019: “超声波清洗机ML31800” and “ML31800”. They show different industrial cleaning units under the same reference. [1] [2] The reviewed text does not explain whether these are revisions, options or separate examples.

The first image shows covered sections and external controls; the second shows open tanks. Neither image establishes the function, dimensions or operating setting of each stage. Use the first entry as the reference for this page; request a current drawing and labelled stage list before approving an order.

Do not decode “31800” into litres, wattage or transducer count. None of those meanings is established by the reviewed source. Its five-times-manual-speed and no-surface-damage claims have no stated trial conditions and are not used as guarantees.

A cabinet photograph cannot answer basket capacity or thermal/electrical demand. Confirm supply voltage, installed/operating loads, water quality and flow requirements from the offered specification. Avoid estimating them from model digits or the number of visible controls.

1. Identify the sample: record its drawing, material, actual soil and initial condition.
2. Set the target: agree the residual-contamination, surface-condition and dryness checks relevant to its next operation.
3. Run the intended load: record the basket, quantity, orientation, proposed chemical and process settings.
4. Inspect the difficult locations: use the agreed method for internal features as well as visible surfaces.
5. Record the complete cycle: include handling, rinsing and drying where those are needed.
6. Approve a repeatable process: retain the configuration, test report and limits governing a future batch.

The source gives no acceptance threshold, extraction method, particle-count report or cleanliness classification. The buyer and supplier must agree an appropriate method; this page assigns no invented standard or numeric residue limit.

Check whether the trial includes all needed rinse/dry equipment. If the result depends on a separate dryer or a different basket, include that boundary in the purchase and acceptance agreement.

HSE’s immersion-cleaning guidance explains that chemical risks depend on the substance and the actual use; it directs users to supplier information and safety data sheets and notes that ultrasonics generate heat. [3] This general UK guidance does not certify ML31800 or prescribe a cleaning recipe.

The public listing’s “no pollution” description supplies no effluent composition or disposal plan. Treat spent bath, rinse water and removed contamination as part of the site review. The chemical supplier’s approved conditions and the cleaner’s limits must be compatible.

• A released drawing with stage functions, tank/basket space, loading limits and utility connections.
• The agreed configuration, controls, included baskets, rinse/dry equipment and protective arrangements.
• A sample acceptance procedure linked to the part and full processing cycle.
• Installation, commissioning and operator/process instruction responsibilities.
• Maintenance instructions, consumables, spare availability and support scope.
