Various problems will occur during the use of shot blasting machine and sand blasting machine. The following Stark Hardware Network will bring you common problems and treatment methods:
1. Dust collector dust contains too many projectiles
The air volume of the separator is too large, and the air vent baffle is properly adjusted until the dust removal effect can be ensured, but the projectile is not sucked out.
Second, the dust collector has low dust removal efficiency
1. Dust collector fan wiring error, fan reverse, rewiring
2. The filter cartridge inside the dust collector is not installed or damaged, or the filter cartridge is missing.
3. The connection of the dust removal pipe is not well sealed, and the sealing of each part is guaranteed.
4. The workpiece that was cleaned did not fall sand as required, the molding sand remained too much, and the dust in the dust removal inlet was too high.
5. The dust collector backflushing mechanism is not activated, or the number of times of activation is small, the dust blocks the filter cartridge, and the dust attached to the filter cartridge is removed in time.
3. The bucket elevator does not work.
1. Clamp and remove the oversized particles at the bottom of the hoist
2. The belt slips, adjusts the transmission wheel tensioning device, tightens the belt
3. There are too many pellets at the bottom of the hoist, stop in sequence and remove the pellets.
4. The cleaning effect of the shot blasting machine is not ideal.
1. Insufficient supply of projectiles, appropriate addition of new projectiles
2. The direction of the shot blasting machine is not accurate, and the position of the directional position of the blasting machine is adjusted.
3. The particle size is different, and the particle size is re-selected.
4. The pellets are agglomerated or used for too long, and the pellets are replaced.
5. The cleaning room door switch is not working or can't open
Door shaft lubrication is not good, add lubricant
6. The machine does not move agilely or does not follow the delineation action.
1. Regarding electrical component damage, check and replace
2. Excessive dust and dirt in the electrical box, poor contact at electrical contacts
3. Time relay is too dusty, dirt, and poor contact at electrical contacts
Seven. The screw conveyor does not work
1. The pellets are clogged, stop in sequence and clear the pellets
2. The screw shaft is bent to correct or polish the outer diameter of the blade.
3. The screw shaft weld is broken and re-welded
Eight. Separator separation effect is poor
1. Uneven flow screen, adjust the flow control panel to reach the full curtain
2. The wind speed in the separation zone is different, adjust the butterfly valve of the separator air outlet to make the wind speed of the separation zone reach 4~5m/s, and adjust the position of the first and second adjustment plates.

How are modern steel beam bridges constructed?
Modern beam bridges that can carry road traffic and railroad are made of steel or reinforced concrete which can also be prestressed or post-tensioned. First step in building of a Beam Bridge is placing of cofferdams which are constructed around each column location in the riverbed.
Why is steel used to construct bridges?
Steel is an ideal material for bridges. It is an essential part of modern bridges because it is strong, can flex without fracturing and has a long life, even in the harshest conditions. It can be used to build bridges of any length because of its durability and ease of manufacture and maintenance.
How long do steel bridges last?
Bridges are typically designed to provide 30 years of service. The actual length of service depends a lot on the amount of stress the bridge is subjected to.
