Abstract
The present invention relates to an energy saving normal pressure hot water boiler heating system which uses a variable water motor with constant rotation speed to recycle the potential energy of a normal pressure hot water boiler heating system. The variable water motor with constant rotation speed is additionally arranged at the end of a water return pipe adjacent to a boiler in the existing normal pressure hot water boiler heating system so that an output shaft of the variable water motor with constant rotation speed is directly or indirectly connected with a shaft of a water pump. Heating return water enters the water motor to impact the gear faces of the water motor so that gears drive the output shaft to do work and the potential energy of the hot water in the heating system is recycled by recovering and converting the potential energy into kinetic energy. Simultaneously, the present invention also solves the problems of water leakage and high waterpower impact in the heating system, has the characteristics of novel structure, energy saving, electricity saving, no pollution, etc., and is the energy saving normal pressure hot water boiler heating system integrating both economy and practicality.
Description
Technical field
Normal pressure hot water boiler onergy-saving heat supply system of the present invention is a kind of variable water motor that utilizes, the energy-saving heating system of the potential energy recycling of normal-pressure hot-water boiler heating system.
Background technology
Hot water system is used comparatively at large at present, and the normal-pressure hot-water boiler heating system is also very general.But because normal-pressure hot-water boiler is a bearing boiler not, the boiler top is provided with atmospheric communicating pipe and is communicated with atmosphere.Though solved the safety problem of boiler operatiopn like this, because atmospheric communicating pipe is arranged, make that the adjustment of system is cumbersome, metal run out and the hydraulic blow problem happens occasionally.The large-sized boiler potential energy that heating produces to high-rise building is bigger simultaneously, can not utilize again, causes huge energy waste.Therefore the national Specification normal-pressure hot-water boiler is 2.8MW to the maximum, and this has in fact seriously hindered the development and application of normal-pressure hot-water boiler.At existing problem in the prior art, a kind of normal pressure hot water boiler onergy-saving heat supply system of research and design, existing problem is very necessary in the prior art thereby solve.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the objective of the invention is normal pressure hot water boiler onergy-saving heat supply system of research and design, thereby solve metalling run out and hydraulic blow and potential energy recycling problem of normal-pressure hot-water boiler heating system existence.Normal pressure hot water boiler onergy-saving heat supply system of the present invention is by the driven by motor water pump, and the hot water in the boiler is delivered to the user through feed pipe, constitutes after return pipe returns boiler.End at return pipe inserts the variable water motor, and the output shaft of variable water motor is connected with the power transmission shaft of water pump.The combination of the three sleeve gear motors that variable water motor of the present invention is made up of a gear wheel and three pinions.The gear wheel of variable water motor of the present invention is connected by freewheel clutch with output shaft, and freewheel clutch is that the output shaft by output shaft and gear wheel junction is processed into the helical teeth shape, and the roller that is contained between helical teeth is formed.The invention provides a new normal pressure hot water boiler onergy-saving heat supply system.Owing to installed the variable water motor additional, the big or small gear teeth face at the high-pressure hydraulic impact water motor with certain potential energy rotates gear, and gear wheel drives output shaft and rotates, and output shaft does work to water pump.The potential energy that has reclaimed heating system utilizes again so on the one hand, makes the pressure of backwater obtain discharging on the other hand, has alleviated the impact of backwater, has solved and has metalled run out and the hydraulic blow problem.Because the variable water motor by a gear wheel and three three groups of gear motors that pinion is formed, can suitably be regulated the by-pass valve control of three water inlets as the case may be, make wherein one group, two groups or three groups of gear motor actings, flow is regulated.The effect of freewheel clutch is when the output shaft rotating speed when the variable water motor is higher than the rotating speed of gear wheel, and when promptly the firm starter motor of system was not done work, freewheel clutch was thrown off, and the helical teeth on the output shaft drives roller and rotates, and makes roller slide to the helical teeth tooth root.When the variable water motor did work, when the rotating speed of gear wheel surmounted output shaft, roller was taken to helical teeth crown position by gear wheel, made the tightly interlock of gear wheel and output shaft, made output shaft output acting.
The effect of the variable water motor among the present invention is that the potential energy that reclaims heating system utilizes saves energy again.Having solved heating system simultaneously metals run out and the hydraulic blow problem.The effect of freewheel clutch is to reduce the electric motor starting electric current, and gear wheel drives output shaft and drives water pump during the motor acting.Gear wheel and output shaft were not thrown off when motor did not do work.The effect of motor is starting system and overcomes friction loss in the water flow process and the overall efficiency loss of pump motor.
