Description
Technical field
The invention belongs to electronic micropump chemical industry feeding technique field, be specifically related to a kind of method of carrying out the motor cooling, and adopt the energy saving and environment friendly electronic micropump of cooling certainly of this method design through the raw material of carrying.
Background technique
Water pump is the machinery of carrying liquid or making the liquid supercharging.It sends mechanical energy or other external energies of prime mover to liquid; Liquid energy is increased; Mainly be used for carrying liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., the liquid that also can carry liquid, gaseous mixture and contain suspended solids.The technical parameter of weighing pump performance has flow, inhales journey, lift, air horsepower, water-horse power, efficient etc.Flow is meant the amount of liquid of exporting through pump discharge in the unit time; Lift is that unit weight is carried the energy increment of liquid from pump intake to outlet.The efficient of water pump is not an independent performance parameter, and it can for example flow, lift and air horsepower be by formula calculated and tried to achieve by other performance parameter.Otherwise known mass flow, lift and efficient also can be obtained air horsepower.The power source of motor-drive pump is a motor.
Motor is meant according to the law of electromagnetic induction realizes electric energy conversion or a kind of calutron that transmits.Its main effect is to produce driving torque, as the power source of electric consumer or various machineries.Motor always has the sub-fraction loss to be transformed into heat when carrying out transformation of energy, and it must constantly distribute heat through motor housing and environment, and this process is a cooling procedure.
The conveying of liquid charging stock is often through motor-drive pump in the chemical engineering, and in the working procedure, along with the rising of motor temperature, the efficient of pump can reduce, and flow and lift reduce, and long term high temperature work also can cause machine operation unusual, reduction of service life.
Motor cooling at present or through natural convection or pass through the external refrigeration device; The heat that above method does not all produce motor is used; And meanwhile many chemical reactions need carry out under the condition of room temperature being higher than; The viscosity of some liquid charging stock big or under low temperature environment, need heating to reduce viscosity after could carry with water pump, otherwise need use powerful device conveying such as oil hydraulic pump instead.
In numerous new energy, Hydrogen Energy will become the optimal energy of 21 century.This be because, under the situation of coal, gasoline and hydrogen of burning identical weight, the most energy that hydrogen produces, and the product of its burning is water, do not have lime-ash and waste gas, do not pollute the environment.Therefore the generation of Hydrogen Energy and utilization are by broad research.Wherein can reduce the energy consumption in the Chemical Manufacture and reduce cost, be expected to substitute the technology of " water electrolysis hydrogen production " that be called as electricity-eating tiger with methyl alcohol, water reformation hydrogen production.Application number is to disclose a kind of miniaturization packaged type hydrogen producer and method in 201210088410.7 the Chinese patent, promotes for the use of Hydrogen Energy and lays a good foundation.Said hydrogen production process comprises the steps:
Step 1: the first alcohol and water is delivered to the heat exchanger heat exchange through pump, gets into the gasification room gasification after the heat exchange;
Step 2: methanol vapor after the gasification and water vapour get into reformer chamber, and reformer chamber is provided with catalyzer, and the temperature of reformer chamber is 370 °-409 °;
Step 3: be provided with the preheating temperature-controlling mechanism between reformer chamber and the separation chamber, in order to the gas of heating from reformer chamber output;
Said preheating temperature-controlling mechanism is as the buffering between reformer chamber and the separation chamber, shortens the temperature difference between reformer chamber output gas temperature and the separation chamber's temperature, makes that the temperature of the gas exported from reformer chamber is identical or approaching with the temperature of separation chamber;
Step 4: the temperature in the said separation chamber is set at 400 °-450 °, and the temperature of separation chamber is higher than the temperature of reformer chamber; Be provided with the palladium membrane separator in the separation chamber, obtain hydrogen from the aerogenesis end of palladium membrane separator.
Wherein at first need carry the gasification of heat exchange of first alcohol and water to heat exchanger and gasification room in the step 1, just need be heated than importing reformer chamber after the higher temperature again and carry out hydrogen production reaction.The conventional electric-powered micropump is unfavorable because of motor radiating, and the too high proper functioning that can influence motor of temperature can not satisfy the requirement of the feed of hydrogen producer in the actual using process.
