  • Due to the machine's working environment being prone to intense vibrations and impacts, constantly observe the dynamics of various parts during operation. If you detect abnormal noise or other irregularities, shut down the machine immediately for inspection and repair before resuming operation. If hydraulic system connectors leak or components become loose, shut down the machine for adjustment and tightening. After ensuring everything is normal, you can resume operation. Before completing each shift, lower the hydraulic hammer to the lowest position and retract all other hydraulic cylinders to their shortest length. If moving a distance, keep the mast leaning backward. For the machine's components, accessories, and electrical equipment, perform regular inspections, especially the connections in the wiring of the motor. During operation, there should be designated personnel for guidance. The guide and the operator should check signals with each other before work and cooperate closely. At the start, use a bell or other methods to signal and inform surrounding personnel to move away. The machine should start at a low speed and gradually accelerate to high speed.

    It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

  • 1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.
