This invention relates to the field of hydraulic pump testing and provides a testing platform for hydraulic pump production. The platform includes a testing bench body with multiple equidistantly arranged filter and defoaming components arranged in a built-in oil tank. Each filter and defoaming component includes a tube, with cylinders connected to both sides of the tube via lugs. Inside the tube, from top to bottom, are sequentially arranged a filter chamber and a defoaming chamber. A filter element is positioned at the center of each filter chamber. A guide tube is positioned between the outer periphery of the filter element and the inner wall of the tube. A power transmission mechanism is positioned below the guide tube to drive the guide tube to raise and lower, adjusting the filtration flow area of ​​the filter element. This allows the platform to meet the differentiated needs of high-precision filtration for small-flow pumps and stable operation with low pressure drop for large-flow pumps, effectively enhancing the platform's adaptability to various working conditions of different flow rates and models of hydraulic pumps, and greatly improving the platform's versatility and practicality.

The application provides a flat compact generator, and belongs to the technical field of generators, which solves the problems of large volume, complex structure and low heat dissipation efficiency of the existing generator. The generator comprises a front end cover, a casing, a rear end cover and a rear cover cover. The outer part of the front end cover is provided with an air outlet mesh cover. The outer part of the upper end of the casing is provided with a wiring board and a wire outlet box. The inner side of the wire outlet box is provided with an automatic voltage regulator. The inner part of the casing is fixedly provided with a main stator. The front end of the rear end cover is provided with an excitation stator. The rear cover cover is arranged at the rear end of the rear end cover. The inner part of the rear end cover is provided with a bearing. The inner ring of the bearing is fixedly provided with a main shaft. A plurality of closely arranged disc couplings and a locking plate are sequentially arranged on the front end surface of the main shaft from back to front by locking screws. A heat dissipation fan blade, a main rotor and an excitation rotor are sequentially arranged on the main shaft from front to back. The rear side end surface of the excitation rotor is provided with a rectifier bridge. The application realizes flat and compact design, and optimizes the smoothness of the internal cooling air duct to improve the heat dissipation efficiency.
