What are the key components of Suspension Shot Blasting Machine?

Suspension Shot Blasting Machine is a device that cleans, removes rust or strengthens the surface of a workpiece by suspending the workpiece and spraying shot blasting media at high speed. It is widely used in surface treatment of castings, forgings, steel, metal components, etc. The efficiency and stability of the suspension shot blasting machine depend on the joint action of multiple key components. The design and maintenance of each component have an important impact on the operation effect, service life and production efficiency of the equipment. The following are the main key components of the suspension shot blasting machine:

  
1. Shot Blasting Wheel
Function: The shot blasting wheel is the core component of the suspension shot blasting machine, which is responsible for accelerating and spraying the shot blasting media (such as steel shot, steel sand, etc.) onto the surface of the workpiece. The shot blasting wheel is usually driven by a motor and has a rotor and blades inside, which can generate centrifugal force to eject the shot sand at high speed. Through high-speed rotation, the shot blasting wheel evenly sprays the shot sand onto the surface of the workpiece to complete the functions of cleaning, rust removal, and strengthening.
Maintenance: The blades and stators of the shot blasting wheel are easily worn parts, so they need to be checked for wear regularly and replaced in time. In addition, the dust in the shot blasting machine should be cleaned regularly to ensure the fluidity of the shot blasting medium.

  
2. Drive System
Function: The drive system is responsible for transmitting the power generated by the motor to the shot blasting machine, conveying device, hanging device and other components to ensure the coordinated work of each component. The drive system is usually composed of motor, reducer, chain, belt, gear, etc.
Maintenance: Regularly check the various components of the drive system to ensure the tension of the chain and the wear of the gear. If abnormal noise or vibration occurs, the lubrication of the drive system should be checked in time to prevent excessive wear.

  
3. Suspension System
Function: The suspension system is used to support and move the workpiece so that the workpiece can be evenly treated by the blasting sand in the shot blasting machine. It is usually composed of chains, hooks, tracks, etc. The workpiece is suspended on the track through the hanging device, and then moved to the shot blasting area as the conveying system operates.
Maintenance: Regularly check the tightness and wear of the chain to ensure the strength and stability of the hanging device to prevent the workpiece from falling or the hook from loosening.

  
4. Shot Media Recycling System
Function: The shot media recycling system is responsible for collecting and screening the shot sand after blasting, removing impurities and debris from it, and recycling it again. The system usually includes a recovery bucket, a conveying device, a screening device, etc., which can effectively recover and clean the shot blasting media and reduce waste.
Maintenance: Ensure the smooth operation of the recycling system, regularly check the screening device and conveyor belt to avoid the pollutants of the shot sand affecting the recycling efficiency. At the same time, the residues in the recycling system should be cleaned regularly to ensure the quality of the recycled media.

  
5. Dust Collection System
Function: During the shot blasting process, a large amount of dust and fine debris will be generated. The function of the dust collection system is to collect and filter these dust and debris in time to keep the working environment clean and reduce the harm to the machine and operators. The dust collection system usually includes a dust hood, a fan, a dust collector, a filter, etc.
Maintenance: Clean the dust collector and filter regularly to prevent them from clogging and affecting the dust removal effect. Check the operation of the fan to ensure that the equipment can continuously and effectively remove dust from the air.

  
6. Control System
Function: The control system is the brain of the suspended shot blasting machine, responsible for the automatic operation, parameter setting, fault alarm, etc. of the equipment. The control system is usually composed of PLC (Programmable Logic Controller), touch screen, human-machine interface (HMI) and various sensors, which can accurately control the operation status of the equipment.
Maintenance: Regularly check the operation of the PLC program and sensors to ensure the accuracy and stability of the control system. If there is a control error or equipment abnormality, the fault should be promptly checked.

 
7. Blast Chamber
Function: The chamber is the area where the workpiece interacts with the shot blasting medium, and the cleaning, rust removal and strengthening of the workpiece surface are completed in this area. Wear-resistant materials are usually used inside the chamber to withstand long-term high-intensity shot blasting operations.
Maintenance: Regularly check the inner wall, ground and other places in contact with the shot blasting medium in the chamber to ensure that there is no wear or damage. If the parts are found to be aging or damaged, they need to be replaced in time to ensure the efficiency and safety of the operation.

 
8. Nozzle
Function: The nozzle is a key component for ejecting the shot blasting medium from the shot blasting machine to the surface of the workpiece. It controls the ejection flow and direction through precise design to ensure that the shot blasting medium evenly covers the surface of the workpiece.
Maintenance: The nozzle is often worn, especially when dealing with workpieces with greater hardness. It is necessary to regularly check the wear of the nozzle, replace or adjust the nozzle angle and ejection direction in time to ensure the consistency and efficiency of the ejection effect.

  
9. Electrical System
Function: The electrical system provides power support for the suspended shot blasting machine to ensure the normal operation of the machine. The electrical system usually includes power supply, distribution cabinet, switch, contactor, line, etc.
Maintenance: Regularly check the cable connection and contact points of the electrical system to ensure that there is no leakage or short circuit to avoid electrical faults affecting the operation of the equipment.

  
10. Safety Devices
Function: Safety devices are used to ensure the safety of operators. Common safety devices include emergency stop buttons, safety doors, photoelectric sensors, etc., which can stop the machine in time when a fault or abnormality occurs to prevent injuries to personnel or damage to equipment.
Maintenance: Ensure that all safety devices can work properly, and regularly check the emergency stop button, door lock and sensor to ensure that they respond quickly and effectively.

  
Summary:
The key components of the suspended shot blasting machine include the shot blasting machine, transmission system, suspension system, shot blasting medium recovery system, dust removal system, control system, workroom, nozzle, electrical system and safety device. Each component plays a vital role in the normal operation of the equipment. Through precise design and reasonable maintenance, the high efficiency, stability and long life of the suspended shot blasting machine can be ensured.
