The invention relates to the technical field of automobile machining equipment, in particular to an automobile part assembling auxiliary device which comprises a profile cabinet. The switching part is arranged at the top of the profile cabinet and extends into the profile cabinet; the feeding parts are arranged on the periphery of the switching part, and the number of the feeding parts is four; the adjusting parts are arranged on the two sides of the bottom of the feeding part. A driving belt wheel is driven to rotate through an output shaft of a servo motor, the driving belt wheel rotates to further drive a feeding transverse shaft and a grooved wheel to rotate by a certain angle through the transmission effect of a power belt and a driven belt wheel, bolts located in grooves of the grooved wheel are conveyed to the tops of two clamping turning plates, and under the gravity effect, the bolts are clamped. The bolt naturally falls off from the groove of the grooved wheel to the tops of the two clamping turning plates, and the gap between the clamping turning plates is smaller than the diameter of a nut of the bolt, so that the bolt is clamped between the two clamping turning plates and is kept in a vertical state to wait for a worker to take the bolt next time, supply is achieved according to needs, and the bolt is prevented from being accumulated at an assembly station.

The present invention relates to the field of fuel cells, and in particular to a simulation device for a fuel cell stack, comprising a stack simulator, a BOP system, a simulated membrane electrode water permeability generation module, a simulated hydrogen reaction consumption module, a simulated stack anode resistance drop module, a hydrogen recycling module, a simulated product water vapor generation generation module, a simulated air reaction consumption module, a simulated stack cathode resistance drop module, a simulated stack cooling resistance module and a simulated stack control module. The fuel cell simulation stack is used to simulate the entire process of material reaction, the stack simulator is used as a simulated reaction site for the fuel cell, and the feed system of the BOP system is used to feed reactant hydrogen and air as well as coolant into the stack simulator. The simulated stack of the present invention is more reliable for reliability and life testing of a BOP system and its components, and the reliability and life testing of the BOP system will not be unable to be continued due to damage to a real stack.

The utility model provides a three-phase multi-stage separator for petroleum and natural gas, and belongs to the technical field of three-phase separators. Comprising a shell, a plurality of rectiblocks are arranged in the shell at intervals and divide the shell into a liquid inlet chamber, a layering chamber and a discharge chamber, the liquid inlet chamber of the shell is connected with an oil inlet pipe, the discharge chamber is internally connected with a water outlet pipe through a water separation assembly, and the bottom wall of the end, away from the oil inlet pipe, of the shell in the discharge chamber is connected with an oil outlet pipe; a gas collecting cylinder with the top connected with a gas outlet pipe is fixedly arranged on the shell and located at the top of the discharge chamber, a demister is arranged in the gas collecting cylinder, a water retaining cap and a water collecting ring are sequentially arranged in the gas collecting cylinder and located under the demister, a drainage pipe is connected to the bottom of the water collecting ring, and one end of the drainage pipe extends to the bottom of the shell.
