Users are increasingly demanding the quality of automobiles and their parts. Brakes are the key components of automobiles and their product quality and functional reliability are particularly important. Brake pump leakage is one of the most prominent quality problems in automotive parts. It is a hidden quality problem. The manufactured product can not find the problem from the appearance, it will not produce oil seepage phenomenon at the beginning of use, but after using for 1 month or more, some products will see oil seepage. This phenomenon occurs in many products. It all happened.
To solve this problem has some difficulties, and the verification is more difficult. In recent years, the author has carried out some explorations and studies on the oil leakage problem of the sub-pumps. In terms of the key factors affecting the oil leakage of the brake sub-pumps and their solutions, some conclusions have been drawn. Experience and effective methods are described below. Choosing a reasonable method of precision machining of the cylinder bore, and strictly controlling the roughness of the cylinder bore, the machining process of the cylinder bore of the cylinder bore using the finishing method of the cylinder bore grinding. There are two ways of finishing: rolling and grinding.
Rolling process is currently a more advanced finishing process, but the material is HT250's sub-pump. During the blank manufacturing process, due to the slight changes in the material and casting, aging treatment, the partial hardness of the sub-pump rough is uneven. Rolling pressure is difficult to flatten the local hard spots, the surface of the pump hole during the rolling process will also increase the hardness, the local contour peaks and valleys of the cylinder hole (the peaks and valleys will accelerate the wear of the sub-pump bowl, damage the cup and oil spills ), it will be more difficult to eliminate. In addition, due to the poor plasticity of the cast iron material, it has notch sensitivity. After being calendered, the surface of the cylinder hole is serrated at the microscopic level. During the use of the brake, the piston of the cylinder is moved axially, and the lip of the cup is under high pressure. With the cylinder hole activity, axial grooves are drawn, resulting in oil leakage.
For the meat marinating solution we refer to meat tenderizer, Saline mixer, Saline injector(brine injection systems), vacuum massage tumbler.
Saline injector can evenly inject the brine and salt auxiliary materials into the meat blocks, which can shorten the pickling time and greatly enhance the taste and yield of the meat products. The machine can be adjusted with stepping rate, stepping distance, injecting interval and injection pressure according to the technological requirements. Then the brine and salt auxiliary materials can be injected into the meat evenly and continually to reach the optimal effects.
While vacuum tumbler makes meat rolled in the drum under vacuum condition, similar to pulmonary respiration (make product to inflation and shrink alternatively). It makes meat salted evenly, increases the adhesive quality and taste and ensures the freshness of meat.
