This invention discloses an electronically controlled suspension cylinder, an electronically controlled suspension system, and engineering machinery. The electronically controlled suspension system includes two electronically controlled suspension cylinders, a central rotating body, and an accumulator. Each electronically controlled suspension cylinder includes an electromagnetic directional valve and a suspension cylinder. The valve port of the electromagnetic directional valve is connected to the oil port of the suspension cylinder via a pipeline. The electromagnetic coils of the electromagnetic directional valves of the two electronically controlled suspension cylinders are connected and then connected to the central rotating body. The oil ports at the top of the two electronically controlled suspension cylinders are connected, and an accumulator is installed on the connecting line. This invention associates the activation signal of the electronically controlled suspension system with the vehicle's travel signal. Whenever the vehicle is in motion, the electronically controlled suspension system activates. When activated, the two electronically controlled suspension cylinders and the accumulator are interconnected, providing a shock absorption effect. This invention uses the electromagnetic directional valve and the suspension cylinder in conjunction, eliminating the need for a hydraulically controlled check valve assembly. The suspension system activation is reliable, and there is no risk of instantaneous closure.

This utility model discloses a detachable aseptic spray drying collection device, relating to the field of spray drying material collection technology. It includes a bottle body with a sealing valve at the top. By fitting the outer wall of a sealing sleeve onto the inner wall of a feed column, the ring plate fixed to the outer wall of the sealing sleeve engages with the inner wall of the ring groove. This allows workers to quickly seal the bottle body using the sealing valve, separating the device from the feed pipe, effectively isolating airflow, significantly reducing material volatilization, dispersion, and moisture absorption during collection and transfer, improving yield, and reducing environmental and cross-contamination. By matching the inner wall of the sealing valve with the outer wall of the sealing ring, the inner wall of the sealing valve abuts against the top of the bottle body. A support plate slides on the outer wall of the bottle body until its top abuts against the bottom of the sealing ring, facilitating control of the sealing valve's sealing of the channel between the bottle body and the feed column to prevent material overflow from the bottle body.

This utility model belongs to the technical field of rice washing devices, and discloses a rice washing device, including a basket assembly for holding rice for washing, and a box assembly for holding water for washing rice. A water circulation component is provided on one side of the box assembly for water intake and circulation for washing rice. The basket assembly is inserted into the top of the box assembly. The box assembly includes a box body, with an overflow trough on the top circumference of the box body. The top surface of the overflow trough is higher than the top surface of the box body. A return water pipe is provided at the bottom of the overflow trough, with its bottom end penetrating into the box body and equipped with a check valve. A waste discharge pipe is provided in the middle of the bottom of the box body, and a waste discharge valve is installed on the waste discharge pipe. The water circulation component includes a water pump, with its inlet connected to the box body. In this rice washing device, the cylindrical filter screen at the bottom of the basket intercepts rice, allowing sand and gravel to sink to the conical bottom of the box; floating bran is discharged through the overflow trough, achieving three-stage separation of sand, rice, and bran.

The application provides a vacuum brazing process for improving the oxidation resistance of a GH4738 and GH3536 alloy assembly, and relates to the technical field of improving the oxidation resistance of an assembly of two different component alloys. The method comprises surface treatment of alloy parts to be welded to obtain clean alloy parts; assembling and fixing the two alloys; prepositioning of the filler metal; and finally, vacuum brazing heat treatment of the assembly with the filler metal. The application controls the gap size of the two alloy brazed joints by synergistically controlling the type and amount of filler metal, so that the alloy assembly has unexpected effects in terms of oxidation resistance, and the service life of the assembly in a high-temperature oxidation environment is improved. After the process of the application, the assembly reaches the complete oxidation resistance level under the condition of high-temperature oxidation at 730 DEG C, and the oxidation resistance is at least 1 times higher. The method is stable, easy to implement, low in cost, high in efficiency, and conducive to large-scale industrial production and popularization and application.
