①This test is carried out during the commissioning before leaving the factory. The limited air supply type generally reaches the limited air volume. Therefore, the judgment rules for this item are the same for the limited air supply type and the residual air supply type.
7.2.3 Factory inspection should be carried out at the manufacturer, but when the "equipment" specifications are large and the manufacturer is unable to carry out inspection, it can be inspected on the user's site.
Marking, packaging, transportation, storage
Each "equipment" shall be equipped with a product label in a conspicuous position on the pressure water tank. The following items shall be indicated on the label. a
Equipment name;
Product mark;
Maximum working force, MPa,
Water supply flow, m/h;
Water supply pressure, MPa
Total weight, k
Factory number:
Factory date:
Manufacturer name:
Overall dimensions.
The dimensions and technical requirements of the label shall comply with the provisions of B8. The following documents shall be attached to the "equipment" when it leaves the factory and sealed in a waterproof pocket.

8.8 The "equipment" should be stored indoors in a dry, well-ventilated environment without corrosive media. If stored outdoors, measures should be taken to prevent rain, sun and moisture.2 The second test method (only applicable to factory inspection) a. For residual air supply type "equipment", check whether the suction sound can be heard at the suction valve when the water pump stops (starts) during normal operation of the "equipment"; whether the pressure gauge on the air supply tank quickly returns to zero; b. For limited air supply type "equipment", check whether the suction sound can be heard at the suction valve sometimes and not sometimes during normal operation of the "equipment" when the water pump stops (starts), and the two states appear cyclically for an indefinite number of times. 6.2.6 Exhaust device test
6.2.6.1 Opening and closing sensitivity test
After the "equipment" is operating normally, artificially inflate to simulate the opening and closing operation of the exhaust device, and check whether the exhaust device is sensitive to opening and closing. 6.2.6.2 Water leakage test
JG/T 3010.2—1994
Use a 100ml measuring cup, measure the water leakage by the volumetric method, and use a stopwatch to time it, and check whether the water leakage meets the requirements of 5.3.4.2f. 6.2.7 Air stop device test
After the "equipment" is operating normally, simulate the operating conditions of the air stop device; after the air stop device is operated for 3 minutes, check whether the instantaneous flow of the flow meter is zero; b.
24 hours after the test of item cb, check whether the pressure drop of the pressure gauge on the air pressure water tank within 24 hours meets the requirements of item 5.3.4.3d. 7 Inspection rules
Type inspection
Type inspection should generally be carried out in any of the following situations: 7. 1. 1
Trial production and identification of new products or old products for transfer to factory production; after formal production, when there are major changes in design, process, and materials that may affect product performance; during normal production, regular or periodic inspections should be carried out; when the product is discontinued for one year and normal production is resumed; when the factory inspection results are significantly different from the last type inspection; when the national quality supervision agency proposes a type inspection requirement. 7.1.2, during type inspection, the specified items should be inspected item by item, and the inspection results should be filled in the form, signed and stamped by the inspection personnel. The inspection items should comply with the provisions of Table 5.
7.2 Factory inspection
7.2.1 Before leaving the factory, the "equipment" should be inspected by the manufacturer's quality assurance department to ensure that the product quality meets the requirements of this standard. 7.2.2 "Equipment" should be inspected for each unit before leaving the factory. For unqualified items, they should be repaired and retested until they are qualified. If they cannot be repaired, they will be judged as unqualified or scrapped. The test results should be filled in the form, signed and stamped by the inspector. The test items should comply with the provisions of Table 6. Table 5
