The invention relates to the technical field of casting machining, and discloses a casting die cavity inlet molten aluminum anti-oxidation device which comprises a heat preservation furnace arranged in a casting rack. A crucible used for storing molten aluminum is arranged in the heat preservation furnace, a furnace cover is assembled on the top of the heat preservation furnace, and a machine shell is fixedly connected to the top of the furnace cover. And the liquid lifting part serves as a conveying runner for connecting the crucible and the casting mold cavity and comprises an adjusting pipe which is rotationally connected to the interior of the furnace cover in a damping mode, a liquid lifting pipe extending into the crucible is assembled at the bottom of the adjusting pipe, and an adjusting piece used for adjusting the inner diameter of a liquid lifting channel in the adjusting pipe is arranged in the adjusting pipe. The anti-oxidation device for the molten aluminum at the inlet of the casting die cavity can effectively solve the problems that in the prior art, the structural parameters of the riser tube are designed in a fixed mode, only the molten aluminum flow requirement of a single-specification casting can be met, and the batch alternate production requirement of multi-specification castings is difficult to meet.

The mixed foaming system comprises a water inlet assembly, a liquid storage assembly and a mixing assembly, and the water inlet assembly is connected with an external water source; the liquid storage assembly contains cleaning liquid; the mixing assembly comprises a first Venturi tube, a mixing pipeline and an air pump, the water inlet assembly is connected with the mixing pipeline through the first Venturi tube, a negative pressure opening of the first Venturi tube is connected with the liquid storage assembly, and an air conveying opening of the air pump is connected with the mixing pipeline. The water inlet assembly is connected with the mixing pipeline through the first Venturi tube, the negative pressure opening of the first Venturi tube is connected with the liquid storage assembly, the cleaning liquid is extracted from the liquid storage assembly through negative pressure generated when water flow passes through the first Venturi tube, and the automatic liquid suction function can be achieved without arranging an independent peristaltic pump; the negative pressure opening of the first Venturi tube is connected with the liquid storage assembly, and the gas conveying opening of the gas pump is connected with the mixing pipeline, so that suction of cleaning liquid and injection of gas are independently completed through water flow negative pressure and the gas pump.

This invention discloses a control method for a piston cooling spray hook, relating to engine control technology. The method involves acquiring the engine's oil pressure and temperature, and combining these to obtain a first oil flow requirement for the oil pump. A second oil flow rate for the piston cooling spray hook is calibrated based on the engine's real-time throttle opening, and the change in oil flow rate of the piston cooling spray hook is obtained based on the change in the second oil flow rate. This change in oil flow rate is then superimposed on the first oil flow requirement to obtain a target flow requirement. Finally, the oil pump is controlled to output an oil flow rate consistent with the target flow requirement. This invention achieves coordinated control of the oil pump flow rate and the piston cooling spray hook flow rate, ensuring lubrication and cooling functions are met under high loads, while reducing oil flow rate and decreasing the driving power of the oil pump under low loads.
