Concrete mixing plant overall equipment maintenance system

If you want to use for a long time, and the maintenance of its own inseparable, concrete batch plant equipment used must be done carefully, will improve to a certain extent the life and reduce the frequency of machine failure, haomei machinery engineer based on years of study summarized the knowledge of plant equipment.

⑴ each time after work, mixing stations are responsible for staff should be cleaning and maintenance items:

① clean up stirred dust inside and outside of the tank wall, at the discharge port, stirring shaft and concrete wreckage of the unloading door, water

Rinse

If necessary, put a small amount of stone and water and stir for a few minutes after release.

Wash car boxes, additional agent and its supply system.

② frozen season working out pumps, additive pumps, water tanks, additive tank, water, residual water in the pipeline of additional agent, additives to prevent damage to pump and piping, and additional agents to start the pump pump 1-2 minutes.

⑵ weekly inspections and maintenance of concrete mixing station project:

① manual pump if needed filling grease;

② all lubrication points must be lubricated;

Note: the lubrication point is located in the mixer shaft, weighing and storage hopper doumen axis, the tape transport, machine roller, pressure roller,

Rollers, bearings, drive chain, screw on the shaft, bearings and host at the lower end gear and other places.

③ check blades, scrapers, stirring arm wear and adjust the gap or replace if necessary.

④ check bolts there is no loosening of the vibrator;

II check the compressor crankcase lubricating oil quality. Replacing them when necessary;

F check the Electrical contactors, static and dynamic contact of the relay is damaged and burned;

C regular maintenance items to check the discharge door seal, should be adjusted when the gap is too large,

Seal gap is generally about 2mm.

① Blade adjustment (including 180 ℃ after the resize), continue to use. When liner fixed-countersunk head screws exposed liner should be replaced when the surface lining plate;

② check if the gearbox lubrication deterioration, or less than the requirements and, if necessary, add or replace;

③ check large gear grinding;

④ damage;

⑤ water, additive system for examination there shall be no leakage;

⑥ components, such as electric power, gear, vibration, air cylinders, filters, in line and in the light of concrete batching plant manufacturers

Maintenance manual requirements;

⑦ concrete mixing plant equipment,

Should be serviced once a half a year, check the reliability of all bolt connections, overhaul period at around 4,000 hours of work in General should overhaul time.

D belt machine repair and maintenance:

① the internal installation of the gear motor, 150th synthetic EP industrial gear oils, oil injection volume must be in strict accordance with the data plate values.

Too much oil or too little can affect the efficiency and normal operation of the roller. Electric roller working 200-300 hours after replacing the drum, then once every 500 hours oil change, changing oil oil should be two plugs into screw and rotate the drum so that it is in the lowest position, until the all the gear motor oil put out so far.

② rear tensioning roller bearing Interior grade grease calcium injected ZG-5, and coated with grease on the screw. After each stage, should promptly clean up end of tape surface, roller and roller surface residues.

Note: the tape machine must be started under no-load conditions, otherwise there is risk of motor damage hormones.
