Problems solved by technology

Since there is only one flowmeter, the existing two test devices can only measure the water flow of a certain type of turbine blade flow channel and air film hole. When using the same test device to measure the water flow of turbine blades with different flow When the flow rate is high, it will cause the problem of low measurement

Abstract

The invention relates to a water flow rate testing device of a turbine blade of an aviation engine. The water flow rate testing device comprises a water tank, a coarse filter, a water pump, a pressure gauge, a fine filter, a main path voltage regulation valve, a blade clamp, a worktable, a bypass flow passage, at least two parallel measuring branch lines, a temperature sensor and a pressure sensor, wherein the bypass flow passage is provided with a bypass adjusting valve; a cutoff valve and a flowmeter are arranged on each measuring branch line from the water inlet end to the water outlet end; the flowmeters on the measuring branch lines have different ranges. The water flow rate testing device of the turbine blade of the aviation engine has the advantages that the water flow rates of flow passages and air film holes of different turbine blades can be measured by one testing device, and the measuring accuracy is improved.

Description

technical field [0001] The invention belongs to the field of aero-engine non-standard parts, in particular to a water flow test device for engine turbine blades. Background technique [0002] According to the development requirements of the turbine blades of the engine, it is necessary to conduct a water flow test on the blades. By measuring the water flow of the air film holes and flow channels of the turbine blades, the conditions of the air film holes of the blades and the processing of the internal flow channels can be inspected to provide a reference for the selection of installed blades. This is convenient A water flow test device is required. There are mainly two types of existing aero-engine turbine blade water flow testing devices. The first structural principle diagram is as follows Figure 6 As shown, it consists of water tank 1, water tank switch 2, coarse filter 3, water pump 4, pressure gauge 5, buffer 20, fine filter 6, main road pressure regulating valve, fl...
