Abstract

The effectiveness of the use of aircraft largely depends on its operational qualities, the timely identification and elimination of the causes of failures and malfunctions. The purpose of this work is to determine the technical condition of an Aircraft plunger pumps. An assessment was carried out on NP-89, which is a plunger pump, to determine any leaks across all four plungers. Also, the design and characteristics of plunger pumps were analyzed, leading to the development of a method for assessing the technical condition of the pump. Based on the result obtained, the volumetric efficiency is 98% which shows that the technical condition of the pump is acceptable. Furthermore, a technological process for conducting a test on the technical condition of a plunger pump using a stand was also developed.
