Description
Technical field
The invention belongs to the continuous source quality regulation technology category of laboratory test, particularly relate to laboratory test continuous source quality regulation system and water supply method.
Background technology
China is household electrical appliance production and consumption state maximum in the world, many water household electronic products; Such as electric water heater, washing machine, dishwasher, the electronic toilet, domestic solar water heater etc., could use after needing to connect water source.For the sound development that specification electrical apparatus industry is orderly, the personnel safety of protection user, country and relevant industrial department successively introduce, formulate and promulgated a series of technical specifications and standard, comprise the safety to product, performance, the standard of efficiency, such as GB4706.1 " the safety first part of family expenses and similar applications electrical equipment: General Requirement ", GB4706.11 " particular requirement of the safe quick-heating type storage-type electric water heater of family expenses and similar applications electrical equipment ", GB4706.12 " particular requirement of the safe storage-type electric water heater of family expenses and similar applications electrical equipment " GB4706.24 " particular requirement that the safe electric of family expenses and similar applications electrical equipment is washed ", GB/T20289-2006 " storage-type electric water heater ", GB12021.4-2004 " electric washer energy consumption limit value and energy efficiency grade " etc.In these standards and guidelines, all corresponding requirement is proposed to testing process quality of water.Along with the change of constantly bringing forth new ideas of electric equipment products, make can more comprehensively, more accurately, more fully the technical indicator of reactor product and quality product just must have system that a set of water supply capacity is very strong for the test of product to the detection of product.The waterworks in current laboratory has well solved that water supply water temperature is constant, fluctuation degree is little and the problem of automatization, but in water quality regulation method being in the degree regulated manually, urgently improves.Comprehensive currently available products standard, mainly proposes pH value, water hardness and specific conductivity (or resistivity) corresponding requirements to test water water quality.
At present, no matter be the specialized laboratory of quality supervision unit or the test organization of electrical equipment manufacturing enterprise, in the adjustment of test quality of water, all adopt the mode of static manual shift.Specific practice is exactly the needs according to water quality regulation, water is piled in a water tank, in water, adding appropriate water quality regulation material, (such as electric conductivity regulates and adds ammonium phosphate or sodium-chlor, hardness regulates and adds calcium oxide, pH regulator adds hydrochloric acid or sodium hydroxide solution), with agitator or poking bar, stirring is carried out to solution and make it even, at difference sampling and measuring analog value, repeatedly such process, until meet standard-required, then provides to test and uses water.After completing with water, re-start water filling and regulate, can again supply water.
Obviously, there is a lot of not enough, inconvenience in existing water quality regulation and water supply method, below the defect particularize of just existing mode as follows:
1, the method for existing water quality regulation adopts artificial or semi-automatic mode, regulates efficiency very low, and time cost is large.With single water tank, water and Auto-regulator are mixed, tentatively determine feeding quantity according to the experience of testing crew and Theoretical Calculation, by the mode of agitator or hand mixing, solution is mixed, then measure in the different positions sampling of container, whether judge water quality evenly and meet the requirement of water concentration.Constantly repeat time operation, until meet water supply requirement.According to such method, only each adjustment will take half an hour by 1 hour, and labor intensive, efficiency are very low.
2, existing method limits by water tank capacity at water supply capacity.Keep the certain of water flow, the amount of capacity that water supply capacity depends on water tank of single water: capacity is large, and water supply time is long, and water quality regulation is more difficult; Capacity is little, and water supply time is short, and water quality regulation is relatively easy, but all just cannot continue to supply water after complete at Water in Water Tank in any case.This makes the test that cannot complete some products when testing, or makes test data deviation become large.
3, existing method causes large waste.Under existing method, substantially solve the above problems, the general method adopting multiple water tank to regulate different quality and Large Copacity water tank.Large Copacity water tank often occurs that test water consumption is much smaller than water tank water capacity, and making to have tested the aqueous solution a large amount of in rear water box will discharge and waste, and increases the pollution of environment.
4, existing method can also cause laboratory to test inconvenient, efficiency step-down.Due to the problem of water quality regulation, make test setup time elongated, laboratory all needs when actually operating to discharge water plan, detects and also will carry out plan according to water plan.So often cause certain day use water not enough, within second day by the time, continue to use, within certain day, use water is excessive, and cannot carry out the situations such as detection arrangement, efficiency is very low.
