The utility model discloses a kind of drainage mechanism for air compressor air receiver, belong to air compressor auxiliary equipment technical field, a kind of drainage mechanism for air compressor air receiver, including main pipeline, the one side of the main pipeline is equipped with stop valve, the one side of the stop valve is equipped with three-way joint, the one side of the three-way joint and side are respectively threadedly connected with connecting pipe one and connecting pipe two;By setting up the automatic drainage assembly formed by U-shaped pipe and check valve, using siphon principle and gravity effect, the timed automatic discharge of condensate is realized.When the pressure generated by the weight of the water accumulated in the U-shaped pipe is sufficient to overcome the opening pressure of the check valve, the valve opens, and the water is quickly discharged under the action of negative pressure and gravity. This process does not require power drive, there is no risk of jamming of moving parts, the structure is extremely simple, reliable and durable, and has strong resistance to oil contamination and impurity interference. It fundamentally solves the problem of easy clogging and damage of traditional automatic water drain.

A production apparatus and processing method for thin-walled micro-pitch high-efficiency heat exchange tubes are disclosed, relating to the field of high-efficiency heat exchange tube production technology. The production apparatus of this invention includes a frame, a tie rod, a core head, a lead screw module, a servo motor, a claw plate, and a rolling head. One end of the tie rod is mounted on the frame and parallel to the bottom of the frame. The end of the tie rod away from the frame is connected to the core head. A servo motor is mounted on the end of the frame away from the tie rod. The output end of the servo motor is connected to the lead screw module. A claw plate is mounted on the lead screw module. The rolling head is mounted on the frame. The high-efficiency heat exchange tubes produced by the method of this invention are of great significance for energy saving, water saving, saving operating costs, and reducing reinvestment. They also have advantages such as low resistance, small size, and material saving.

The application discloses a kind of based on model predictive control algorithm's pneumatic system positioning control method, comprising: the hardware composition and action principle of pneumatic system are analyzed, the mathematical model of pneumatic system is divided into the mass flow equation of gas, the mathematical equation of slide valve, piston force balance equation, based on above-mentioned three equations construction pneumatic system slide valve opening and system output mathematical model;Valve core is analyzed to find the midpoint position of making the stable inaction of both sides of cylinder, design pneumatic system setting process, according to setting process determines the various parameters of pneumatic system slide valve opening and system output mathematical model;Based on the setting process of design, design pneumatic system model predictive controller, this method designs pneumatic system model predictive controller, suppresses each kind of disturbance in system, inside and outside, realizes to pneumatic system and carries out good control.
