Implemented on March 1, 1994
JB/T7140.2-93
3.3.1 The bottom plate of the mobile medicinal bath machine and the bottom of the medicinal bath pool of the fixed medicinal bath machine should be inclined at an angle of 3° to 5° to the horizontal plane. 3.3.2 When the nozzle is spraying at the standard working pressure, except for the propulsion nozzle, the spray angles of other nozzles should be consistent, and the intersection of air jet and liquid spray is not allowed. Replacement phenomenon.
3.3.3 The height of the upper nozzle from the ground should be adjustable, and the adjustment height should be between 1200 and 3000mm. 3.3.4 The material used for the upper and lower spray racks should be hard plastic, and have certain acid, alkali and corrosion resistance. Other materials with performance not lower than that specified in this article can also be used instead.
3.3.5 The nozzle should be made of materials with strong acid and alkali resistance and high corrosion resistance. 3.4 Assembly and appearance
3.4.1 The parts and components used to assemble the medicinal bath machine must be inspected and qualified, and the purchased parts must have a certificate of qualification and be inspected by the inspection department before entering the factory. It can be assembled only after it is qualified.
3.4.2 The upper spray rack should rotate smoothly and flexibly without any jamming. 3.4.3 The connections of all fastening parts and connectors must be firm and reliable. 3.4.4 There should be no jamming or collision between the rotating parts. 3.4.5 The control valve, welded pipe fittings and pipeline elbows are not allowed to leak under normal working pressure. The bearing temperature rise shall not exceed 30℃.
The gearbox works smoothly and reliably and should be able to meet the use requirements. The weld corrugation of the welded parts should be uniform and smooth, and there should be no defects such as burn-through, missing welds, cavities, etc. 3.4.82
External The exposed non-processed surface should be smooth and neat, and there should be no obvious defects such as burrs, protrusions, depressions and pores. 3.4.92
3.4.10 Parts and components in contact with the liquid medicine should have good anti-corrosion performance, and the anti-corrosion paint layer should be selected according to the chemical-resistant coating provisions in Table 1 of JB/T5673.
4 Quality assurance period
If the user complies with the assembly, use and storage conditions specified by the manufacturer, within 1 year from the date of purchase, if the product is damaged due to poor manufacturing quality and cannot work normally, the manufacturer shall be responsible for repair, replacement (except wearing parts) and refund. 5 Test method
The performance test and production test of the drug bath machine shall be carried out in accordance with the provisions of JB/T7140.3. Other items of the drug bath machine shall be inspected in accordance with conventional methods. 6 Inspection rules
6.1 Factory inspection
6.1.1 The drug bath machine must be inspected and qualified by the quality inspection department of the manufacturer before it can be shipped, and it shall be accompanied by a product certificate. 6.1.2 Each medicinal bath machine shall be tested for operation with clean water before leaving the factory, and run at rated speed for 20 minutes, and shall meet the requirements of Articles 3.3.2 and 3.4.2 to 3.4.10 of this standard. If there is any failure, it must be repaired and qualified before leaving the factory. 6.2 Type inspection
6.2.1 The product shall be subjected to type inspection when one of the following conditions is met: a.
Test and finalization of new products or old products transferred to the factory for production; during normal production, if there are major changes in structure, materials, and processes, which may affect product performance; during normal production, type inspection shall be carried out once every 3 years; when the product is discontinued for 2 years and production is resumed;
When the national quality supervision agency proposes a type inspection requirement. 6.2.2 Sampling plan and judgment rules
6.2.2.1 The medicinal bath machine takes N=28 units (pieces) as an inspection batch. However, when sampling among users, the size of N is not limited. 6.2.2.2 The drug bath machine adopts the normal inspection sampling plan specified in GB2828 and uses the general inspection level I. 4
JB/T7140.2-93
6.2.2.3 The various inspection items of the drug bath machine are divided into Class A, Class B and Class C according to their impact on product quality. See Table 2 for the unqualified categories and Table 3 for the sampling plan.
6.2.2.4 The method of surprise sampling is adopted to randomly select samples from the batch submitted for inspection (products within the past year). 6.2.2.5 During the inspection, the inspection conclusions are made for each type of unqualified items. When the number of unqualified items in the inspected categories is less than or equal to A., the batch of products is judged to be qualified; when the number of unqualified items in any or more of the inspected categories is greater than or equal to R, the product is judged to be unqualified.
