Abstract

The invention discloses a hydraulic safety block performance testing method, comprising the following steps: step 1: valve core assembly surface detection; step 2: hydraulic safety block pumping pressure test; step 3: air tightness test; and step 4: overpressure relief test. The invention belongs to the technical and quality control of a factory, and adds a set of test methods on the basic requirements of the design to control a hydraulic safety block to be safe and reliable in the final state. Through the working principle of the hydraulic safety block and the analysis of the working conditions of each component, the invention develops a reliable and feasible performance testing program to ensure the effectiveness and safety of the system.

Description

technical field [0001] The invention relates to the field of safety assurance of a hydraulic system of a diesel engine, in particular to a method for testing the performance of a hydraulic safety block. Background technique [0002] The hydraulic safety block is the safety guarantee of the hydraulic system of the diesel engine. After the hydraulic oil is pressurized, it first enters the hydraulic safety block system, and then is output to each hydraulic system and hydraulic system components by the hydraulic safety block. The hydraulic safety block is one of the most important components in the hydraulic system of a marine diesel engine. Receive high-pressure lubricating oil provided by two oil inlet systems, one of which is provided by the electric pump station (used in the starting phase of the diesel engine), and the other is provided by the mechanical pump station (used during the normal operation of the diesel engine). The high-pressure lubricating oil is regulated by...
