A vertical internal coating machine is taught, which may be used with bodies such as cans (2 piece, 3 piece, draw, redraw,) and including cylinders, containers and any similar body. In the machine cans or similar bodies are vertical in the machine's star wheel rather than horizontal, and the bodies are sprayed with the star wheel in continuous motion without stopping and starting. The machine teaches that a plurality of spray guns may be provided for each pocket of the star wheel. By means of the machine an improved line layout is devised which may eliminate the need to raise the bodies immediately prior to a necker by allowing the vertical can internal coating machine and internal bake over to be disposed on any level of the facility, upper, lower, mezzanine, etc. In green aspects, the machine may use negative pressure cabinets / hoods and positive pressure tunnels to entrain volatile organic chemicals emitted by the spray guns and coated bodies and may send these VOCs to a VOC desctruction device, such as an oven.

The method applies refrigerant mixed by two or above compositions to change circulating media concentration through a separation unit; when load is increased at heat pump operation system separates composition of high boiling point through separation unit to raise concentration of low boiling point media in circulation for enhancing ability of heating at low temperature environment; when load is decreased high boiling point composition of high concentration stored in low pressure liquid storage tank at bottom part of separation unit is absorbed systematically through heating means to decrease heat generating amount of system.

The invention provides a vehicle engine automatic start-stop control system and method based on vehicle-road coordination. The method includes: when temporarily parking, the communication module obtains the traffic light information, and determines whether the vehicle is at the traffic light intersection; if so, the analysis module sends the corresponding information to the vehicle start-stop module according to the red light waiting time and the information of the preceding vehicle in the same lane, combined with the preset control strategy. On the contrary, the analysis module obtains the stop time sent by the vehicle information module to determine whether the engine needs to be turned off. When the engine is turned off, if the vehicle information module detects that the vehicle needs to be started, the analysis module sends a control command to start the engine to the vehicle start-stop module. The invention realizes that when a vehicle is waiting at a traffic light intersection, it can intelligently control the start and stop of the engine according to the time of the red light and the information of whether the preceding vehicle is traveling, thereby realizing the purposes of smoother running, quick start, fuel saving and the like of the vehicle.

The invention provides an acceleration and deceleration control method in the trajectory planning of a numerical control system. Assuming that the total running time of the numerical control system during processing is T, the total running time is divided into seven time periods, which are respectively 0 to t 1 , t 1 ~t 2 , t 2 ~t 3 , t 3 ~t 4 , t 4 ~t 5 , t 5 ~t 6 , t 6 ~t 7 , define the time interval of each time period as T i (i=1,2,3...,7), then T 1 The corresponding time period is from 0 to t 1 , T 2 The corresponding time period is t 1 ~t 2 , T 3 The corresponding time period is t 2 ~t 3 , T 4 The corresponding time period is t 3 ~t 4 ,T 5 The corresponding time period is t 4 ~t 5 ,T 6 The corresponding time period is t 5 ~t 6 ,T 7 The corresponding time period is t 6 ~t 7 , the algorithm expression used when planning the acceleration and deceleration curve model is where j(t) is the function of jerk with respect to time t, j max For the maximum value of jerk during operation, the acceleration and deceleration control method in the trajectory planning of the numerical control system provided by the present invention intersects with the prior art, the control algorithm model is simpler, the jerk curve is smoother, and the numerical control is directly reduced. The system starts and stops.

The invention relates to an online lubricating oil sampling device, and belongs to the technical field of lubricating oil sampling. The device comprises a device body, a transition connector, an oil level gauge, a sampling interface, a dustproof cover and a sampling tube; one inner end of the device body is connected with the transition connector; the transition connector is mounted on a to-be-sampled device; the external end of the device body is connected with the oil level gauge; the sampling interface is arranged on the device body; one end of the sampling interface is connected with the sampling tube; the sampling tube is inserted into the to-be-sampled device through the transition connector after extending into the device body; the dustproof cover is used for enclosing the samplinginterface; the sampling interface is internally provided with a spring and a ball; when oil sampling is not carried out, the spring pushes the ball to realize sealing; and when oil sampling is carriedout, the ball is pushed away by the spring.
