Abstract

The invention discloses an on-line environment high-temperature test chamber for an aviation kerosene hydraulic pump, which includes a chamber body (24), wherein a working chamber (6) is arranged inside the chamber body (24); the working chamber (6) is connected with a testboard (21) through a pipeline interface A (12); a pressure release door (7) is arranged at the upper part of the chamber body (24); an explosion venting box (8) is arranged above the pressure release door (7); an explosion-proof heater (15), an explosion-proof blower (1) and a water cooler (16) are arranged at the lower part of the chamber body (24) side by side; and the chamber body (24) is connected with a testboard transmission device (17) through a sealing head (20). The on-line environment high-temperature test chamber provided by the invention has the characteristics of high temperature, big temperature rise velocity, explosive prevention and explosive resistance, and can meet the requirements of an on-line working condition test of the aviation kerosene hydraulic pump with high temperature, big temperature rise velocity and high possibility of explosion.

Description

technical field [0001] The invention relates to a high-temperature test device, in particular to an online environment high-temperature test device for an aviation kerosene hydraulic pump. Background technique: [0002] The aviation kerosene hydraulic pump online environment high temperature test chamber is an environmental chamber that combines the aviation kerosene hydraulic pump test bench and places the aviation kerosene hydraulic pump in the online working condition in the working room of the high temperature test chamber for testing. The high temperature test chamber is required to provide a high temperature above 215 degrees in the aviation kerosene environment, a temperature rise rate of 21 degrees per minute and the function of preventing combustion and explosion. [0003] Due to the strict, harsh and difficult test environment, there is currently no ready-made mature high-temperature test chamber in China that can meet the online environmental test of this type of ...
