A Two-Wire Progressive Distributor

Abstract

The invention discloses a two-line progressive distributor. The two-line progressive distributor comprises a control strip, a first metering strip, a second metering strip and a third metering strip, wherein internal oil ducts among the control strip, the first metering strip, the second metering strip and the third metering strip are intercommunicated; reverse control is carried out on a control plunger through alternate pressure transformation of pressure boosting and pressure reduction of two main oil ducts so as to drive each group of metering plungers at two sides to perform progressive oil separation actions respectively; the control plunger controls a plurality of groups of metering plungers to respectively complete progressive metering oil separation actions along two directions, the oil separation action situations of a plurality of oil outlets at two sides are respectively detected and protected by a first action indicating rod and a second action indicating rod, and the partition protection for lubricating points is realized. According to the technical scheme, the two-line progressive distributor is reasonable in structure layout, simple in system configuration, reliable to work, convenient to organize and produce, small in size and convenient to use; the cost is reduced; and the limitation in prior art is overcome.

Description

Technical field [0001] The invention relates to the technical field of lubrication, in particular to a double-line progressive distributor. Background technique [0002] In a single-line or dual-line high-pressure centralized lubrication system, the lubricant supplied by the lubrication pump needs to be metered and separated through a distributor, and a quantitative amount of lubricant is injected into each lubrication point. In the existing publicly known technology, the used distributor is usually a progressive type or a two-wire type, but there are the following problems in use: [0003] First, the progressive distributor adopts pressure oil to drive each working plunger to move in a progressive sequence. Each working plunger can complete the oil metering, oil flow reversal and pressure delivery of the oil, reaching two sides. The purpose of the oil outlet. As long as the lubrication pump is continuously supplying oil, the working cycle of sequential oil supply from the progre...

AI Technical Summary

Problems solved by technology

However, the structure of the double-line distributor is far more complicated than that of the progressive distributor. The former needs to be equipped with a metering plunger and a control plunger for every two oil outlets, and the latter only needs to be equipped with a plunger to complete the metering and control. function, so the cost of products with the same specifications is almost twice the difference, and the volume is large, which is very inconvenient to install

At the same time, since the action of the metering plunger of each group of the two-line distributor is independent, an independent action signaling protection link must be set up for the protection of important lubrication points, and the system configuration is relatively complicated.

Therefore, there are certain limitations in practical use
