High-efficiency type1. All welds must be inspected frequently. When ultrasonic testing is used, the inspection length shall not be less than 25% of the length of the weld; when radiographic testing is used, it shall be 15%. The intersection of welds must be inspected. 5.2.2 Weld quality assessment: When ultrasonic testing is used, it is qualified if it reaches Grade II in GB/T11345; when radiographic testing is used, it is qualified if it reaches Grade II in GB/323. Suspicious areas found during ultrasonic testing must be further evaluated by radiographic deep flaw detection. 5.1.3 When the seam flaw detection fails, the weld shall be double-checked. If it fails again, it shall be re-checked by 10%. 5.2.4 The number of repairs for the same part should not exceed two times. If it occurs twice, the technical department of the manufacturing unit shall notify the relevant department, and the repair part and number shall be stated in the product quality certificate. 5.3 On-site final inspection after trial operation The front cooler shall be installed in accordance with the provisions of the JCJ and this standard as well as the installation and operation instructions, drawings and technical fees, and no-load and load tests shall be carried out on site. 5.3.1 During the trial operation, 5.3.1.1 The motor shall run at no-load for 2h. 5.3.1.2 The auxiliary motor shall drive the reducer to run for 4h. 5.3.1.3 The main motor drives the cooler to run unloaded for 8 hours through the reducer. 5.3.1.4 The excavator drives the cooler to run loaded for 4 hours through the reducer. 5.3.2 Inspection contents
5.1.1.1 The temperature rise of the supporting wheel bearing (or bushing) shall not exceed 30℃, and the temperature rise of the motor and reducer bearing shall not exceed 30℃. The contact surface length between the wheel belt and the supporting wheel shall not be less than 75% of the width of the sheet. 5.3.2.3 The wheel blocking device is running correctly
5.3.2.4 The damage plate of the cooler and the fixing bolts of other parts shall not be loose. 5.3.2.5 The sealing device and the limiting device of the cooler should remain in normal operation during operation. Marking, packaging, transportation and storage
6. Each single-stage cooler shall be equipped with a product label in an appropriate and obvious position. The type and size of the label shall comply with the provisions of GB/T6915-1999 and shall indicate the following contents:
) Product name and specifications;
) Factory number;
) Date of manufacture;
d) Manufacturer name;
) Main technical data.

6. 2. Packaging of refrigerated components. Packaging should comply with CBT13384 and the requirements of land and water transportation. 6.3 The packaging box should be firm and reliable. The parts in the box should be rainproof and waterproof. 6.4 The parts that are transported in sections should be supported by additional transport support to ensure their correct state and prevent deformation. 6.5 The storage and transportation marks of the packaging box should comply with the provisions of GB191. There should be obvious text symbols on the outside, including: ) Declaration form;
6) Product name, specification Format design: 1) box number, overall dimensions, net weight, weight and shipping mark: 2) manufacturer name.
6.6 The loading materials shall be clearly marked, and the internal calculation and 6.5. The accompanying technical documents include:
a) packing list and complete set delivery list:
) product qualification certificate;
) product installation and use instructions;
d) product general drawing, basic drawing, component drawing. . The simple cooling machine is easy to install and manufacture , and the user should transfer the sample, the parts should be kept in good condition, and the rust and deformation should be avoided. 6.5 Important parts (wheel tyres, large gear rings, etc.) that are prone to deformation during long-term stacking must be placed horizontally. No heavy objects are allowed to be placed on them. A1
