What method can be used to eliminate the cylinder failure of concrete mixing station?

What are the specific aspects of cylinder failure in concrete mixing station?

(1) Cylinder leakage is usually caused by eccentric installation of piston rod, insufficient lubricant, wear and tear of sealing ring and sealing ring, impurities in cylinder and damage of piston rod. The center position of piston rod should be adjusted, the reliability of oil mist detector should be checked regularly, and impurities in cylinder should be removed in time.

(2) The output force of the cylinder is insufficient and the action is not smooth. Piston or piston rod jammed, poor lubrication, insufficient air supply, or there are condensate and impurities in the cylinder. Adjust the center position of the piston rod to check the reliability of the injector. Whether the gas supply pipeline is blocked or not, the condensate and impurities in the cylinder should be removed in time.

(3) The cushioning effect of cylinder is poor. Usually, because of the damage of the buffer seal ring or the adjustment of the screw, the seal ring and the adjustment screw are replaced.

(4) The damage of piston rod and cylinder head is usually due to the eccentric installation of piston rod or the failure of cushioning mechanism. The central position of piston rod should be adjusted in time, and the cushioning sealing ring or adjusting screw should be replaced if necessary.

Advantages of using diesel engines in concrete mixing stations:

Firstly, diesel engine has the characteristics of high thermal efficiency and low fuel consumption. The effective thermal efficiency of diesel engine in hybrid station is 30% and 46%, which is higher than that of high pressure steam turbine and steam turbine, and the fuel consumption is lower.

Secondly, the mixing equipment has compact structure, light weight, power plant and steam turbine. Diesel generator equipment is relatively simple, less auxiliary equipment, small size, light weight, so in the field of metal diesel generator set, the unit effective quality: for 34-68 KX kw/kw low-speed diesel engine, 20 towel high-speed engines, high-speed 48 KX will be 14 kx/kw/kw, diesel engine and steam-powered plant than this index of diesel engine is 4 higher than C.

Station equipment quickly starts up and mixes with diesel, and will soon reach full power: diesel engine pneumatic; it only takes a few seconds in a country's emergency Coze LMM full load to full load. Full-load steam power plants are also very short, and you can start and stop frequently, when the pain is working properly and it takes 3 cents from the start to shut down the diesel engine.

With diesel engine, the consumption of cooling water is small, and sufficient water is needed: dry tile of diesel engine group, cooling water frog 46 will be 2L/(kilowatt). K) and condensing turbine are 48d-610l/(kilowatt/hour), nearly 10 times the difference.

The capacity of diesel engine is single, and the capacity of diesel generator set is from tens of watts to millions of kilowatts. At present, the maximum capacity of domestic units is thousands of dry tiles. The utility model is suitable for large buildings, B bridge construction, tunnel construction, industrial and mining enterprises, military installation and standby power station with single capacity emergency power station. The utility model has a wide selection range and can use more than 10 kinds of capacities and electric loads.

In addition, the mechanical maintenance of concrete mixing station is simple and requires fewer operators. Easy to maintain.
