What methods are used to troubleshoot the cylinder failure of the radial extrusion equipment concrete mixing station?

What are the specific aspects of cylinder failure in radial extrusion equipment concrete mixing plants?

(1) Cylinder leakage is usually caused by eccentric installation of the piston rod, insufficient lubricating oil, wear and damage of sealing rings and sealing rings, impurities in the cylinder, and damage to the piston rod. The center position of the piston rod should be adjusted, the reliability of the oil mist detector of the radial extrusion equipment should be checked regularly, and impurities in the cylinder should be eliminated in a timely manner.

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

(3) The cushioning effect of the cylinder is poor. Usually, the sealing ring and adjusting screw are replaced due to damage to the buffer sealing ring or adjustment of the screws.

(4) The piston rod and cylinder head are damaged, usually due to the eccentric installation of the piston rod of the radial extrusion equipment or the failure of the buffer mechanism. The center position of the piston rod should be adjusted in time, and the buffer seal ring or adjustment screw should be replaced if necessary.

Advantages of using diesel engines in radial extrusion equipment concrete mixing plants:

First of all, the diesel engine of radial extrusion equipment has the characteristics of high thermal efficiency and low fuel consumption. The effective thermal efficiency of the diesel engine in the mixing station is 30% and 46%, which is higher than the high-pressure steam turbine and steam turbine, and the fuel consumption is low.

Secondly, the hybrid equipment is compact and lightweight, including the power unit and turbine. Diesel generator equipment is relatively simple, with less auxiliary equipment, small size and light weight, so on-site metal diesel generator sets, the effective mass of the unit: for 34-68kx kW/kW low-speed diesel engine, 20 towel high-speed engines, high-speed 48kx will be 14kx/kW/kW, the diesel engine and steam power plant ratio of this indicator is 4 higher than C.

The radial extrusion equipment equipment quickly starts and mixes the diesel and will reach full power quickly: the diesel engine is pneumatic; it only takes a few seconds for a state-of-the-art first-aid LMM to be fully loaded to full load. In a diesel engine that has normal working conditions and requires 3 cents from the beginning, the shutdown process of a full-load steam power plant is also very short, and you can start and stop frequently.

With a diesel engine, the cooling water consumption is small and sufficient water sources are needed: for a diesel unit with dry watts, the cooling water will be 46 2L/(kilowatt.K), and for a condensing steam turbine it is 48d-610l/(kilowatt/hour), a difference of nearly 10 times.

The capacity of the diesel engine is single, and the capacity of the diesel generator set ranges from tens of watts to millions of kilowatts. Currently, the maximum capacity of domestic units is thousands of dry watts. The utility model is suitable for large-scale buildings, B-bridge construction, tunnel construction, industrial and mining enterprises, military installations, and backup power stations with single capacity emergency power stations. 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 the concrete mixing plant is simple and requires fewer operators. Easy to maintain.
