MFE5 gear pump unit for oil,Explanation of hydraulic function Fig 3.
Both ME5 MFE5 types have the same hydraulic function. Oil is sucked in at S and flows under pressure through the duct in the. direction P The oil pressure closes valve V and opens valve E3 at the. same time closing valve E1 against spring tension If air is entrained. due to low oil level in the reservoir valve V remains open and di. verts the air or respectively the air oil mixture into the return duct. see bubble o marking in direction R1 Valve C allows oil under. overpressure to flow out into the return duct see cross marking. When the unit stops interval time spring loaded valve E1 opens. and valve E3 simultaneously closes The system pressure at P can. now be released through valve E1 with the exception of a small. amount of residual pressure determined by valve E2 This pressure. release is required for the piston distributors to function correctly. The pressure relief process is shown in fig 4,Explanation of the structural differences. In the case of model ME5 the long screw plug D1 blocks flanged port M5 50 d9. R2 of the return duct The oil returning from valves V C and E1 flows O Ring 48 3. via port R1 through a tube to the separately mounted oil reservoir R2. see fig 1 and 2, In the case of model MFE5 the short screw plug D2 unlike D1 63. with model ME5 leaves flanged port R2 open A plug closes off ex M14 1 5 1. ternal port R1 Flanged port R2 of the return duct drains directly into S 87. the reservoir without any connection threads see fig 3 and 4 63. connection,100 for cable,MFE5 unit variants,Flow Max back. rate pressure,Order No 1 l min bar Design,MFE5 2000 0 5 28 Basic version NBR 88. plastic termianl box,MFE5 3041 0 5 28 Basic version NBR.
