????One of the most frequently received feedback from our customers is that some concrete machines have dissatisfying performance after a period of using. Take concrete mixing machines for example. Many people attach little importance to maintenance in using concrete mixers, the efficiency of which is found to decline later. Why? Generally speaking, the reasons for efficiency decline of concrete mixer machines include consistency of filter elements and oil, influence of working at low temperature and periodic flow of oil.

????A concrete mixing machine has filtration components made of metals and non-metals, both of which may have problems about consistency with oils to be filtered. This consistency further include problems of chemical changes and thermal effect changes. It’s especially critical to guarantee that these changes will not be influenced by high temperature. That’s why all filtration parts must go through a consistency test at high temperature with oils to be filtered before the parts are applied to targeted concrete mixer machines. Running at low temperature has a negative affect on the mixer as well. Some non-metal parts become more vulnerable at low temperature and the density of oils will increase, too. This will correspondingly lead to increase of oil pressure and cracks in filtration parts. The periodical flow of oils are usually unstable. The change of flowing oil amount may make filter elements deform or bend. Repeated bending and deforming from periodic oil flows will cause fatigue damage to filter parts.

????Therefore, it’s critical to guarantee quality of filter elements at high temperature and regular check of the elements in daily maintenance.
