Problems solved by technology
[0003] Since chemical equipment has high requirements on the flow stability of the circulating water system, the instantaneous flow change of the system will affect the quality and output of the product and the safe operation of the pump, such as causing the vibration of the pipeline, generating noise, and even causing equipment safety. Accidents, such as sudden changes in flow that can cause pipe damage and rupture

Embodiment Construction
[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0043] see Figure 1-2 , this embodiment provides an analysis method for the impact of industrial circulating water energy-saving water turbine accident state on the system, assuming that the actual head of the water pump is H, and the height difference between the nozzle of the cooling tower and the liquid level of the pool is H 1 , the total resistance of pipe and nozzle is H 2 , the pressure consumption of the turbine is H 3 , since the pressures are bala...

The invention discloses a method for analyzing the influence of the accident state of an industrial circulating water energy-saving water turbine on a system, and relates to the technical field of industrial circulating water energy-saving water turbine.In the normal working state of the water turbine, the instant water flow change of the flow water turbine is maximum when the flow water turbine flies and is locked, and the flow water turbine is set under the same pressure head for normal operation of the water turbine; if the flow rate in the runaway or locking state is aQ, the instantaneous water flow rate Q'in runaway and locking is suitable for the following formula: deltaQ = Q '-Q, the instantaneous maximum change value of the flow rate of the system which does not cause substantial influence on the system is set as deltaQ', and the magnitude relationship between deltaQ and deltaQ 'is the criterion for judging whether the accident state of the water turbine can cause influence on the system or not.
Description
technical field [0001] The invention relates to the technical field of industrial circulating water energy-saving water turbines, in particular to a method for analyzing the influence of industrial circulating water energy-saving water turbine accident states on the system. Background technique [0002] In the industrial circulating water system, the return water of the system often has a certain return water pressure. Generally, the rich return water pressure is consumed by properly closing the return water valve of the system, resulting in a large amount of energy waste. The energy-saving water turbine for industrial circulating water is used To consume the rich return water pressure, use the return water residual pressure in the circulating water system to drive the water turbine to rotate, and use the water turbine as the power source of other devices or drive the generator to generate electricity, so as to achieve energy saving effect. [0003] Since chemical equipment ...
