Description
Technical Field
The utility model relates to the technical field of shock wave superchargers, in particular to a shock wave supercharger for a circulating system.
Background
The existing closed constant pressure circulation system for central heating, the cold and hot water circulation system for central air conditioner, the cooling water circulation system and the circulation system for secondary heat exchange of domestic hot water are all not separated from the circulation pump. The configuration parameters of the traditional circulating pump are calculated and configured according to the cooling or heating area of the system, the parameters of the circulating pump are the power, the lift and the flow of the motor, wherein the flow is in direct proportion to the cooling and heating area, and the lift mainly aims at overcoming the resistance of a pipe network. Under the condition of keeping the flow of the water pump unchanged, the higher the lift, the greater the power required to overcome the system resistance, the greater the power of the matched motor and the more the power consumption. Therefore, how to increase the lift of the circulating pump and reduce the power of the matched motor under the condition of unchanged flow, and reduce the power consumption become an important problem of energy conservation of the current closed constant-pressure circulating system.
Therefore, the related technical field of the utility model is improved, for example, the prior Chinese patent publication No. CN2866926Y discloses a shock booster, the shock booster is arranged at the outlet of a closed system circulating pump, when the shock booster operates, water from the outlet of the circulating pump enters a compression spray pipe, the sound barrier is overcome in a narrower section of the compression spray pipe section and then enters a fluid straight pipe, the flow speed of water flow in the fluid straight pipe is converted into subsonic speed, wherein in the process that a part of high-pressure water flow is pressed into an annular diffusion cavity from a tilting fluid channel arranged on the wall of the fluid straight pipe, the flow speed is instantaneously converted, pressure shock waves can be generated, the pressure is greatly increased, meanwhile, the other part of high-pressure water flow enters a pressurizing diffusion pipe from the fluid straight pipe, the pressurizing process is completed in the pressurizing diffusion pipe, and the pressurized water flow passes through the fluid outlet and the outlet of the venturi pipe to push the whole circulating system to move.
However, in order to adjust the width of the annular gap channel of the fluid channel, the technology adopts a structure form of two flange sleeves which are mutually connected together through the flange sleeve, and at least one circle of adjusting gasket is arranged between the two flange sleeves. The gap of the fluid channel on the fluid straight pipe can be adjusted by increasing or reducing the adjusting gasket, and then the size of the inlet section of the annular diffusion cavity is adjusted, so that the set supercharging value is ensured to be reached.
However, the adjusting mode needs to increase or decrease the number of adjusting washers, which eventually leads to the relative position change between the two flange sleeves, and further leads to the overall length change of the shock booster. This may result in gaps at the junction after the shock booster is shortened and installed, or may be detrimental to installation after the shock booster is lengthened, with certain limitations.
