Dongguan Humen Meijun Sandblasting Equipment Store specializes in the production of various types of environmentally-friendly and energy-saving shot blasting equipment, sandblasting equipment, paint spraying equipment, dust removal equipment, a total of four series and a variety of products. Need to develop different series of products
The principle of Meijun's road shot blasting machine:
The shot is quickly thrown into the working area at a certain angle, impacting the surface, making it rough and removing the residue.
It is to use the centrifugal force and wind generated by the high-speed rotation of the driving shot blasting wheel to make a certain amount of shots enter the shot tube and accelerate them into the rotating splitting wheel. Throw into the directional sleeve, then throw it through the directional sleeve window, pick it up by the high-speed rotating blades, and continue to accelerate along the length of the blade until it is thrown. The thrown projectiles form a certain fan-shaped stream and impact the working plane. It plays the role of cleaning and strengthening. Then the projectile passes through the rebound chamber with dust and impurities to the top of the storage hopper. The high-powered dust collector separates the pellets and dust from the separation device above the storage hopper. The pellets enter the storage hopper and continue to be recycled, and the dust enters the dust collector through the connecting pipe. After the dust enters the dust collector, it is separated by the filter element and stays in the ash storage bucket and the surface of the filter element. Automatic backflushing dust collector can automatically clean each filter element by backflushing air provided by the compressor. Finally, the inside of the machine is cleaned by the airflow of the matching vacuum cleaner, and the pellets and the cleaned-up impurities are recovered separately, and the pellets can be reused. The shot blasting machine is equipped with a dust collector, which can achieve dust-free and pollution-free construction, which improves efficiency and protects the environment.
Where to use the road shot blasting machine, the scope of use of the road shot blasting machine:
1.It can clean up the asphalt pavement, improve the friction while reducing the asphalt pavement, and reduce the vehicle's slipping accidents;
2. You can change the marking lines on the road, remove the old marking lines and draw new marking lines;
3.The tire marks on the airport surface can be removed, which will be very neat and beautiful after cleaning;
4.It is also possible to remove scale, rust and roughen the inner surface of the ship and the surface of the steel plate to meet the pre-treatment requirements of anti-corrosion coating or heavy anti-corrosion coating;
5, can also be used for tunnel maintenance, equipment is small and environmentally friendly;
6, is a better pavement cleaning tool, not affected by the weather when using;
7. Shot blasting treatment before non-solidified waterproofing can solve the defects of hard hollow, sand, cracks, looseness, ash dropping, uneven unevenness of the waterproof base.
It can be said that the application range of road shot blasting machines is very wide
First, the use of asphalt pavement shot blasting machine
1.Improve road surface roughness and road adhesion
2. Anticorrosive coating of steel bridge deck
3. Maintenance of height and tunnel
4. Maintenance of airport runways
5. Remove markings and cleaning
6. Renovation of oxide bridges on ship deck
Road shot blasting machine startup steps:
1. Turn on the vacuum cleaner
2. Ready to operate shot blasting machine
Make sure the valve handle is in the "closed" position,
Press the button "Control ON"
Insert walking pin
Press "Blast Wheel ON", and then the shot blasting motor starts;
Observe the ammeter, when the shot blasting motor starts, a larger current is required until the motor reaches a certain speed;
When the motor reaches the rated speed, the current will drop to the no-load current state;
3. Set the walking direction to "Backward", the device walks, and then set the walking speed of the device at the walking speed adjustment button;
4.When shot blasting on the concrete surface, only open the valve when the machine is walking, otherwise, a pit will be thrown on the concrete surface in a short time.
Pavement shot blasting machine steps
1.Close the valve handle completely;
2.Release the walking kneading handle, and the walking motor stops;
3. Press the red "Control Off" button, (Control Off)
4. After a few minutes, press "Fan Off" and "Compressor Off" on the vacuum cleaner.
Shot blasting machine maintenance
1. Regular lubrication: The motor and transmission parts of the electric actuator of the shot blasting machine need to be lubricated with lubricating oil, and the viscosity of the lubricating oil changes with the oil temperature. If the viscosity is too low, the wear of transmission parts such as gears will increase; if the viscosity is too high, the operation will be poor. Therefore, regular lubrication can extend its service life.
2. Improve the operating environment: In order to ensure the reliability of the shot blasting machine's electric actuator, it must be ensured that it runs in a suitable operating environment to avoid other environmental factors such as wet environment and short circuit or other faults.
3. Regular inspections: Regular inspections will promptly find hidden dangers of accidents in operation, which will at least help in finding fault factors and avoid detours.
4. Make a good management of the fault account: every fault that has been dealt with must be recorded in detail, including fault phenomenon, fault analysis and search process, fault cause, treatment method, preventive measures, etc. This will not only provide a reference value for dealing with similar problems in the future, but also improve the level of finding fault factors through the fault curve, and achieve the effect of doing more with less.
Technical advantages of pavement shot blasting machine:
"Operations and preparations are simple, organized at any time, and evacuated at any time."
Selected a number of leading electrical control skills such as variable frequency speed regulation and phase sequence maintenance to ensure the accurate completion of various functions
Since most of the equipment is used for outdoor operations and the operating environment is harsh, the temperature difference is large. The inverter of this machine is selected from Taiwan. The other major electrical components are imported from the Schneider brand to ensure the stability of electrical operation and the stability of the entire machine.
The shot blaster is fully tested in the factory for 60 minutes to ensure quality.
The selection of large shot blasting and high shot speed centrifugal shot blasters can significantly improve the finishing power and achieve satisfactory finishing quality. The wear-resistant parts are made of high chromium material.
According to the different conditions of the road, the finishing speed, the amount of steel shots, the pulse backflush time period, the dust removal interval of the dust filter can be adjusted to achieve the desired finishing effect.
The dust collector uses pulse active back blowing dust removal, which can complete successive operations to ensure that the entire construction process is dust-free and pollution-free, which is beneficial to environmental protection and the health of the construction staff.
The pavement structure is basically not damaged during the construction.
The whole machine has a reasonable structure, quick disassembly, and convenient repair and replacement of wearing parts.
