two. Purpose: To verify that the product meets the reliability requirements and to use customer standards when the customer has standards
three. definition:
a) If the temperature and humidity used in the standard are not specified, the default is ±2°C and +2%/-3%RH, respectively.
four. standard
4. Test:
1) Applicable products: The systems and products represented by Shenzhen Delongtai Technology Co., Ltd. are rigorously tested by recognized professional testing organizations, and the management and production processes conform to ISO 9001 and ISO 14001 system certifications. Strict quality control ensures the reliability and safety of systems and products, meets the different needs of customers in different regions of the world, and provides users with high-quality, high-reliability fluid monitoring and control and electrical automation products.
2) Test conditions:
* One piece thin valve plate
* Valve uses multiple connection standards
*Valve seat integrated die pressure
* Connection: clip, ear
3) Test method:
a) Rated input voltage and load of the product, work in the test box at 50°C (60°C) for 2.5h (4.5h), then power off for 0.5h, as a period
b) Check sample output voltage and current per duty cycle
4) Judgment criteria:
a) Definition of failure: It is verified from the user's point of view whether the function of the product is normal, that is, it is defined as failure when the output voltage of the product exceeds Spec.
b) Failure is defined as failure if the product fails to recover at normal temperature during the test
4.2 Product Operation Environment Test: Low Temperature Operation Test
1. Hoist motors: These are used to lift and lower heavy loads in a tower crane.
2. Slewing motors: These motors are responsible for rotating the tower crane.
3. Wire ropes: Wire ropes are used for lifting and lowering loads in a tower crane.
4. Safety devices: These include limit switches, load moment indicators, and anti-collision systems, which ensure safe operation of the tower crane.
5. Control panels: These panels include buttons, switches, and control systems that allow operators to control the movements of the tower crane.
6. Hydraulic pumps and cylinders: These components are used to control the movement of the tower crane's jib and trolley.
7. Electrical components: These include circuit breakers, contactors, relays, and fuses, which are essential for the electrical functioning of the tower crane.
8. Bearings: Bearings are used to reduce friction and facilitate smooth movement of various parts in the tower crane.
9. Brakes: Tower cranes are equipped with various types of brakes, including hoist brakes, slewing brakes, and trolley brakes, which help in controlling the movement of the crane.
10. Ladders and platforms: These are used for accessing different parts of the tower crane for maintenance and repair purposes.
Tower crane spare parts are essential for ensuring the smooth operation and maintenance of tower cranes, as they help in replacing worn-out or damaged components and ensuring the safety and efficiency of the crane.
