Problems solved by technology

[0006] The problem existing in the existing volumetric distributor is: when the pipeline for conveying grease is long and the viscosity of the grease is high, because the fluidity of the grease in the pipeline is poor, when the motor stops rotating, although The pressure at the oil outlet 9 of the decompression mechanism drops to zero, but the pressure in the grease delivery pipeline 7 is still increasing, and the pressure at the first oil inlet 1 is still increasing, causing the oil storage spring 6 to refuse to move. Slow oil output from the first oil outlet 3

Abstract

The invention relates to a volumetric distributor with a depressurizing function. The volumetric distributor comprises a distributor body, an oil grease delivery pipeline, a first oil inlet and a second oil outlet. The volumetric distributor further comprises a plunger type depressurizing mechanism, the plunger type depressurizing mechanism comprises an oil inlet cavity and an oil outlet cavity, the oil inlet cavity is sequentially provided with a second oil inlet, a depressurizing plunger, a plunger spring and a plug, and the depressurizing plunger is in slide fit with the oil inlet cavity; one end of the oil outlet cavity is provided with a second oil outlet, and the other end of the oil outlet cavity is sealed. A communicating pipeline is arranged between the oil inlet cavity and the oil outlet cavity; the second oil outlet is communicated with the first oil inlet, and the second oil inlet is communicated with the oil grease delivery pipeline. The pressure of the first oil inlet can be quickly decreased to zero, and the volumetric distributor is suitable for the long oil grease delivery pipeline and used for treating high-viscosity oil grease. Meanwhile, the volumetric distributor has the advantages of fast oil discharge and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a volumetric distributor with a depressurization function. Background technique [0002] The volumetric distributor mainly refers to the volumetric distributor used for the lubrication of automobile machinery. It is a kind of output end connected to the lubrication pump to distribute the oil output by the lubrication pump to multiple pipelines, and then transported by each pipeline to Equipment for all parts of the car that need to be lubricated. The volumetric distributor can not only lubricate this part to ensure smooth operation, but also avoid overly complicated piping between this part and the lubricating pump. [0003] Existing volumetric oil injection machines generally include a volumetric distributor and a decompression mechanism (refer to figure 1 ), which works like this: [0004] The motor of the positive displacement oil injection machine ...
