Rules and requirements for no-load commissioning of vibrating conveyor

Vibrating conveyor is a kind of equipment that continuously conveys materials by vibration. This vibrating conveyor is mainly composed of exciter, bearing groove, main vibrating spring, frame, etc., which can be used for horizontal, gently inclined or vertical transportation of various loose materials (rising along the spiral groove). The vibrating conveyor can complete the screening, drying, dehydration, cooling, mixing and other processes at the same time. Materials containing a large amount of dust and harmful components can also be transported in sealed cans.

The vibrating conveyor conveys materials through the reciprocating vibration of the conveying trough. There are two basic ways to transport materials in the trough: sliding motion and throwing motion. By reasonably selecting the motion parameters (amplitude, frequency, vibration direction angle and installation angle) of the vibrating conveyor, the materials in the tank can be transported by sliding or throwing.

The commissioning of vibrating conveyor includes no-load commissioning and load commissioning. The following are some rules and requirements for no-load test run of vibrating conveyor!

1. No load commissioning conditions----

① All the above works have been completed and meet the requirements;

② Relevant electrical construction and automatic control construction are completed and meet the requirements;

③ Fill all lubricating points with lubricating grease as required;

④ The area around the conveyor and the passage have been cleaned;

⑤ Electrical system, safety interlocking device, braking device, operation control system and signal system shall be simulated or checked for operation, and their working performance shall be sensitive, correct and reliable;

⑥ Rotate all moving mechanisms to make the input shaft and output shaft of the transmission system rotate for one cycle without jamming; The rotation direction of the motor shall be consistent with that of the conveyor.

2. No load commissioning qualification standard----

① The vibrating conveyor shall be started stably and quickly, with stable vibration, without left-right swing, bounce, impact and abnormal noise;

② The amplitude and vibration direction angle of the conveyor shall not be greater than 10% of the rated value; The amplitude deviation of the front, middle and rear sections of the vibrating conveyor with a length greater than 15m shall not be greater than 10% of the rated amplitude;

③ The temperature rise of rubber spring shall not exceed 50 ℃, the temperature rise of metal spring shall not exceed 70 ℃, and the temperature rise of bearing and motor of eccentric connecting rod vibration conveyor shall not exceed 50 ℃; The temperature rise of solenoid coil shall not exceed 65 ℃;

④ No load commissioning time shall not be less than 4 hours.
