Transcription

1 Progressive distributor VPAC Use: In progressive mode based central lubrication systems. The main features of WOERNER progressive distributors are as follows: Accurate proportioning volumes. Clear and precise arrangement of control channels in spite of smallsize construction. Modular system construction. Quick fault remedy possible without having to loosen the pipeline. Subject to modifications 9 different proportioning volumes selectable in accordance with the lubricant required. Extremely long service life refined sliding surfaces. due to Pluggable monitoring elements can be replaced during operation. No proportioning decrease at the piston monitored. Technical data: Proportioning volume per cycle: 0,... 0,9 cm³ Lubrication point connections at max. : 0 Operating pressure at max.: 0 bar Throughput volume in case of: Oil at max.: 00 cm³/min Grease at max.: 0 cm³/min Delivery medium: Oil viscosity: > cp Grease: up to NLGI category A= Mounting position at the distributor (for visual indication and electrical checking device) at first place A= Mounting position at the distributor (for electrical checking device) at last place B = Mounting point for viewing indicator at distributor (if point A is occupied) D = DPAC proportioning block H = Main line K = Proportioning volume distinctive number M = x M8 fastening threads for assembly of auxiliary units ( see data sheet 08) R = APAD connecting plate S = Mid fastening screw Number of outlets Length "a" Length "s" Weight [kg] 0,0, 7,00 0 9,0,0,90 8, 90,0 Material: Proportioning block: Aluminium Internal parts: Steel Connecting plate: Aluminium Temperature range: C Mounting position: usually as needed Note: In case of heavy vibration or shock load, install the distributor such that piston axes are situated vertically to the main direction of shock impact. An optimum ventilation of the whole lubrication system is the precondition for its functionally safe operation. For quicker ventilation, the flow direction from bottom to top in the distributor is of advantage (inlet on bottom side). The distributor must not be "distorted". Therefore, when mounting it, always be careful that the supporting surface is level. Progressive distributor VPAC Replaces No. Page of EN EN

Without removal of the "Z" screw, no outlet must be locked.

6 Subject to modifications Main line Fig. Functional process fig.... : Monitoring of progressive distributors Leftside bypass line I II Rightside line bypass The lubricant flows from the main line through the rightside ring groove of piston III as well as the bypass line (right) and to the left side of piston I and moves it into its home position. The lubricant displaced by piston I is ejected via the left bypass line through outlet no.. As for instance due to soiling, the flow through a lubricant point line may be prevented. This will cause a piston to get blocked. By virtue of the forced control as depicted in figures up to, the other pistons will be stopped as well. Due to this configuration, the proportioning at all outlets of the distributor can be monitored by means of a sensor at one piston only. III Fig. Mounting note: I After shifting of piston I, lubricant flows to the left side of piston II and pushes it into its rightside home position. The displaced lubricant is ejected via outlet no.. The pistons are provided with an extremely small fitting clearance. Therefore, the pistons, after the dismantling of a distributor, must never be interchanged. Fig. Formula for calculating the lubricant available per lubrication point: After shifting of piston II, lubricant flows to the left side of piston III and pushes it into its rightside home position. The displaced lubricant is ejected via outlet no.. A progressive distributor allocates the delivered lubricant to the individual lubrication points in forced order. Due to the functional process as described herein, a safe proportioning is ensured. II The lubricant q i delivered to a lubrication point i can be calculated as follows Fig. q i = K i (K +K +K...) Q After shifting of piston III, lubricant flows to the right side of piston I and pushes it into its leftside home position. The displaced lubricant is ejected via outlet no.. The continuation of that process is evidenced in the scheme depicted. Q = lubricant delivered to the distributor, K i = distinctive number of the outlet i III Page of 088 EN
