ZU-H、QU-H series pressure pipeline filter

The filter is installed on the pressure pipeline of the hydraulic system to filter out the mechanical impurities mixed in the hydraulic oil and the colloid,asphalt, carbon residue,etc. produced by the chemical change of the hydraulic oil itself,so as to prevent the occurrence of valve core jamming,the blockage of throttle hole gap and damping hole,and the rapid wear of hydraulic components.

The filter is equipped with a differential pressure transmitting device.When the filter element is polluted and blocked until the differential pressure at the inlet and outlet is 035MPa,it will send a signal that the filter element should be cleaned or replaced to achieve the purpose of protecting the system.

Application

widely used in hydraulic systems such as heavy machinery,mining machinery and metallurgical machinery.

Filter medium

water and ethylene glycol in hydraulic oil

Note:*refers to the filtration accuracy, # refers to the filter material. If the medium used is water glycol,the operating pressure is 32Mpa,the nominal flow is 63L/min,the filter material is paper,with transmitter and by-pass valve,the filter model is Zui Bh-h63x*P, filter element model is HX BH-63X*Q.If the filter material is chemical fiber with transmitter,the filter model is qu.bh-63x*Q and the filter element model is HX Bh-63x*Q,the filter material is metal mesh with transmitter,then the filter model is wu-h63x*P and the filter element model is HX - 63x*W.
