What is a progressive distributor? The progressive distributor is the main component in the lubrication system, and thedistributor distributes the input grease from the pump element evenly and sequentially to each outlet. The distributor isgenerally a monolithic design, usually made of monolithic material, which can withstand high pressures. Progressive distributors mainly have two types of plate and block type, in the lubrication system is mostly the use ofplate distributor, that is to sa, each progressive distributor has a start piece, a stop plate and at least three intermediatepieces, the number of intermediate pieces can theoretically be infinite, but no matter what the number, can be combinedwith the start piece and the end piece into a complete whole. Each piece in the middle piece has a working piston andtwo oil outlets, and the oil outlet is located at the left and right ends of the middle piece. Grease or lubrication enters fromthe upper oil inlet, reaches the left end of the piston after passing through the annular groove and pushes them graduallyto the right, so that the lubricant in the piston cavity is slowly drained from the oil outlet in turn. When the piston reachesthe limit position at the right end, the lubricant entering the distributor reaches the right end of the piston through theannular groove on the left, pushing the piston to gradually move to the left, so that the lubricant in the piston cavity isdischarged from the oil outlet; The process is in the opposite direction of piston movement, and accordingly, the lubricantis discharged from the diferent oil outlets in turn. As long as the lubricant entering the progressive distributor maintains acertain pressure, the distributor will work continuously In addition, if the number of intermediate pieces is more than 3,the number of pieces can be followed and so on. As long as the piston in any intermediate piece is stuck and cannot beoperated, the pistons in the other intermediate pieces will be completely blocked, and the entire distributor will stopworking, this ingenious idea makes it extremely convenient to monitor whether the output oil is normal, as long as theintermediate piece is set sense, the proximity switch of the piston action can alarm in time when the piston is blocked.
