Description
Technical Field
The utility model discloses hydraulic oil filtration system of hydraulic press belongs to the technical field of hydraulic press, mainly relates to filtration system of hydraulic press under the special operational environment.
Background
The hydraulic filtering system of the hydraulic machine is used for filtering various impurities in the hydraulic system, and the sources of the impurities mainly comprise: mechanical impurities such as water rust, casting sand, welding slag, scrap iron, coating, paint coat, cotton yarn scraps and the like which remain in the hydraulic system after cleaning; impurities entering the hydraulic system from the outside, such as dust entering the oil filling port, the dust ring and the like; impurities generated in the working process, such as fragments formed by a sealing element under the action of hydraulic pressure, metal powder generated by relative abrasion in movement, colloid, asphaltene, carbon residue and the like generated by oxidative deterioration of oil liquid. After the impurities are mixed into the hydraulic oil, the impurities can be damaged everywhere along with the circulation action of the hydraulic oil, and the normal work of a hydraulic system is seriously influenced, such as the blockage or blockage of a small gap between relatively moving parts in a hydraulic element and a throttling small hole and a gap; the oil film between the relative motion parts is damaged, the surface of a gap is scratched, the internal leakage is increased, the efficiency is reduced, the heat generation is increased, the chemical action of the oil is intensified, and the oil is deteriorated. According to production statistics, more than 75% of faults in the hydraulic system are caused by impurities mixed in hydraulic oil, so that the cleanness of the oil is maintained, and the pollution of the oil is prevented, which is very important for the hydraulic system.
The sagger blank used for sintering the powder in the kiln and used for containing the powder needs to be pressed and formed by a 500t press, the sagger blank is pressed in a special environment with large dust emission, and for the press, a hydraulic system is easy to generate impurities. A filter of a 500t press machine on the market is arranged on one side of the bottom of an oil tank, and hydraulic oil is extracted for filtering. But because fluid has mobility, such filtration mode can say that carry out the random extraction to fluid in the oil tank, and impurity in the oil tank can't be cleared up completely, will overstock impurity in the filter after using a period of time in addition, and impurity is too much to lead to the filter to lose the filter effect, therefore the filter need regularly clear up, all clears up the impurity of filter inside, just can continue to use. When impurities are cleaned, the press machine needs to be stopped, all oil is discharged, and the filter can be detached for cleaning, so that work and production are particularly delayed, and time and labor are wasted in maintenance work. In order to not delay production work, the cleaning time of a filter is usually quantitatively prolonged, and when the filter is cleaned, the oil liquid is thoroughly cleaned once by a large filter. However, whether the filter is frequently cleaned or maintained by matching the filter with a large filter, the oil impurity can not be removed in a time-saving and labor-saving manner on the premise of not delaying production work.
