Two factors determining vacuum degree of vacuum stone lifter

Two factors determining vacuum degree of vacuum stone lifter
 Everyone knows that vacuum stone lifters are used in many industries. Our company has stone vacuum lifters, litchi noodles, light plate lifters and so on. Today we  tell about the degree of vacuum. It is the main parameters of vacuum pumping equipment, such as vacuum pump, micro vacuum pump, micro air pump, micro air pump, micro air pump and so on. Vacuum refers to the density of gas molecules in a device space. It is smaller than the standard state. Vacuum stone lifter determines the vacuum degree by two factors: one is the maximum vacuum degree and pumping speed that the vacuum pump can reach, the other is the leakage of the whole system. The leakage of the system depends on the humidity and temperature of the air. Humidity usually refers to the number of gaseous water molecules. In addition to nitrogen and oxygen, there are many other gases in the air. Water is one of them, so the higher the humidity, the smaller the vacuum. In this way, it is not easy to vacuum the air humidity.           
 Vacuum stone lifter temperature, because any substance from solid or liquid to gaseous needs energy, so the higher the temperature, the more active the molecular movement, the easier to extract it. So the conclusion is that if the temperature of the atmosphere is higher and the humidity of the gas in the equipment is lower, the vacuum effect will be better. In order to meet the dual requirements of energy saving and fast response of vacuum generator, the overall technical scheme of flow self-adjusting jet vacuum generator is proposed. The structure and principle are described below. Vacuum stone suction cup tells the analysis of flow self-regulation principle of vacuum generator. It is mainly composed of Laval nozzle, ejected cavity and mixing pipe, which shrinks first and then expands. It has air supply port, exhaust port and vacuum port. When the ratio of supply pressure to nozzle throat pressure is greater than a certain value, the nozzle emits supersonic jet. Under the action of gas viscosity, the high-speed jet entrains the gas in the ejection chamber and forms a certain degree of vacuum in the chamber.
 Vacuum generator is one of the components of vacuum suction hoist. It is a pneumatic device that uses the jet action of low pressure compressed air to realize vacuum suction. The characteristic of this kind of pneumatic device is that it has no moving parts and uses compressed air as power to produce vacuum adsorption force directly. Compared with other vacuum generators, the advantages of this vacuum generator are small size, light weight, simple structure, no mechanical movable parts, no wear and tear, easy manufacture, low cost, easy installation and use, safe and reliable use of indirect energy, etc.
 The vacuum principle of vacuum stone suction cup is that compressed air is ejected  to the exhaust port at high speed to form a jet flow. Because of the high velocity of the nozzle, the pressure of the nozzle accessories is low, which has the suction effect on the suction port. At this time, when the suction port is closed, the vacuum in the suction tube chamber will rise rapidly to a certain degree of negative pressure, which is the pressure of forming vacuum. The velocity of jet flow of vacuum stone lifter plays a decisive role in the formation of vacuum effect; the diameter of nozzle, the diameter of small end of horn mouth, the shape and size of diffusion chamber will have different effects on the vacuum degree. The vacuum negative pressure produced by the vacuum generator is used to absorb the material by connecting the suction cup at the end of the suction pipe, and then the material movement, lifting and other transportation operations are completed.
