Blade bounce value detection tool of water pump assembly impeller

Abstract

The invention discloses a blade bounce value detection tool of a water pump assembly impeller. The blade bounce value detection tool comprises a supporting plate, a dial indicator, and a dial indicator fixing block disposed on the supporting plate. The supporting plate is provided with a positioning pin, which is disposed in a water pump assembly housing in a clamped manner for the positioning. In the positioning state of the positioning pin, the measuring head of the dial indicator is contacted with the impeller blade. By adopting the above mentioned structure, the blade bounce value detection tool is advantageous in that 1, the dial indicator fixing block is used for fixing the dial indicator, and during the use of the tool, the dial indicator is not required to be calibrated again each time when the detection product is replaced, and therefore the operation is simple; 2, during the measurement, the positioning pin is used for the positioning of the water pump assembly impeller housing, and the measuring head of the dial indicator is contacted with the blade of the impeller, and by rotating the water pump assembly belt pulley manually, the swinging value of the dial indicator can be seen by the eyes, and therefore the measuring data is accurate and stable.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a tool for detecting the beating value of blades of an impeller of a water pump assembly. Background technique [0002] Before the water pump assembly leaves the factory, it is necessary to detect the runout of the impeller of the water pump assembly to avoid the delivery of products with quality defects. [0003] At present, the impeller inspection of the water pump assembly generally fixes the product, uses a dial indicator with a magnetic base, corrects the dial indicator, turns the pulley, and observes the beating value of the dial indicator. Using this detection method, the dial indicator needs to be recalibrated every time a product is tested, which not only wastes the time required for calibration, but also requires a high level of testing for inspectors, which is not suitable for mass production testing of products. When the product is tested, it is necessary to turn...

Problems solved by technology

Using this detection method, the dial indicator needs to be recalibrated every time a product is tested, which not only wastes the time required for calibration, but also requires a high level of testing for inspectors, which is not suitable for mass production testing of products

When the product is tested, it is necessary to turn the pulley to drive the impeller to rotate. During the detection process, the dial indicator is in intermittent contact with the blade. Therefore, the dial indicator moves, resulting in inaccurate measurement results.
