Diesel engine injector water spacer extractor

Abstract

The invention belongs to the technical field of diesel engine maintenance tools and relates to a diesel engine injector water spacer extractor comprising a support beam and support screws arranged on the support beam. The support beam is further provided with a pull screw connected with an expansion pull sleeve; the expansion pull sleeve is composed of a connecting part and an expansion pull part; the connecting part matches with the pull screw; the expansion pull bar is connected with a water spacer. The water spacer is extracted by: inserting the expansion pull sleeve into the water spacer, tightening the pull screw into the expansion pull sleeve to expand the expansion pull sleeve and tightly combine with the water spacer, and downwardly turning a pull nut on the pull screw to downwardly separate the expansion pull sleeve from the pull screw and to drive the water spacer to constantly move down. The diesel engine injector water spacer extractor has the advantages that the water spacer is more convenient to extract, operating efficiency is improved, the water spacer is also protected from damage, and the diesel engine injector water spacer extractor is applicable to popularization and application in extracting water spacers from diesel engine injectors.

Description

technical field [0001] The invention belongs to the technical field of maintenance tools for diesel engines, and in particular relates to a water-separating sleeve remover for fuel injection nozzles of diesel engines with simple structure and convenient use. Background technique [0002] Diesel engines require regular inspections, maintenance, etc. At present, when disassembling and replacing the water-separating sleeve of the fuel injector of a diesel engine, it is generally necessary to remove all the connecting parts of the gas-steel cover first, then remove the gas-steel cover, and select a rod with a similar diameter to the fuel-injector to remove the water-separating sleeve; At the same time, in order to ensure the cylinder pressure, it is necessary to clean the engine block, cylinder head, and replace the seals. It is not only time-consuming and labor-intensive, but also labor-intensive to replace a water-proof jacket, and the maintenance cost increases, which not onl...

Problems solved by technology

At present, when disassembling and replacing the water-separating sleeve of the fuel injector of a diesel engine, it is generally necessary to remove all the connecting parts of the gas-steel cover first, then remove the gas-steel cover, and select a rod with a similar diameter to the fuel-injector to remove the water-separating sleeve; At the same time, in order to ensure the cylinder pressure, it is necessary to clean the engine block, cylinder head, and replace the seals. It is not only time-consuming and labor-intensive, but also labor-intensive to replace a water-proof sleeve, and the maintenance cost increases, which not only wastes material resources, but also increases environmental pollution.
