Principle of the present utility model is: at first make-up water pump outlet is connected with liquid injection port E on the mainframe, then extract in the coolant filling line by make-up water pump, during the filling coolant, the whole valves on the pipeline should be in the enable possition, and coolant is full of all pipelines
3.5.2 coolant to be had appears at when the flexible pipe on the valve is interior on the water tank integrated system, stopping filling is closed the exhaust outlet valve; Unclamp the exhaust bolt on the centrifugal pump, until close this exhaust outlet after the gas emptying in the pump; (please this exhaust bolt of careful operation, leak in order to avoid damage to produce) starts centrifugal pump, makes that medium is in recurrent state in the system, and circulation continuous is closed the centrifugal pump power supply after 10 ~ 15 minutes; Again open liquid injection port E valve, and open make-up water pump and in water tank, replenish medium, the exhaust outlet valve will have medium to overflow when being full of, not termination of pumping this moment, until after no longer including the gas discharge in the hose G, the side closes the exhaust outlet valve, closes liquid injection port valve and make-up water pump power supply, the start trial run confirms that nothing can begin to carry out parameter adjustment when unusual.
Be higher than 30 when spending in temperature, start outer circulation, whole system is full of behind the coolant can cooling to wind-force generating converter, coolant is by flowing out from the B pipe after filtering, be provided with valve and pressure sensor at the B pipe, can control the flow velocity of coolant in the B pipe, again in the inflow radiator hot channel, enter the A pipe after the coolant heat radiation is complete, according to required temperature and directly the coolant of the G pipe of the coolant of joining water box in integrated mix, by flow through D pipe of threeway battery valve, for better control flow through into current transformer speed and the temperature of coolant, be provided with suction pump at the D pipe, pressure sensor and temperature sensor, the pipeline that the coolant of temperature and pressure controlled well just flows through current transformer inside dispels the heat to current transformer, in integrated by C pipe recovery inlet water tank after the circulation of current transformer internal pipeline is complete, be provided with temperature sensor and valve at the C pipe, can better detect the temperature through the coolant behind the current transformer inside, according to the temperature sensor on the CD pipeline can clearly know whole system the temperature difference, and the pressure sensor of BD pipeline can be known the flow velocity of system, thereby can guide the folding of valve to guide the flow velocity of coolant of whole system and the debugging of temperature according to on-the-spot needs, reach satisfied cooling-down effect, when temperature is lower than 30 when spending, circulation in starting, liquid medium is with regard to the AB pipe of not flowing through, directly in the water tank integrated system, heat up, behind D pipe inflow current transformer internal pipeline, reclaim inlet water tank through C pipe and the continuous filter of C pipe.Temperature-10 the degree to 30 the degree between the time, close heater, walk interior circulation.The principle of this device is schematically as follows:
In the utility model: the radiator of frequency converter can flow through laying dust because of cooling-air.Because the radiator laying dust, cooling effectiveness returns reduction, just the excess temperature fault might occur.Under home (free from dust, cleaning), radiator should annually check that once under dusty environment, radiator should often clean.
With rated temperature, when rated load operation, the life-span of the main cooling blower of frequency converter is about 60000 hours.10 ℃ of the every reductions of blower fan temperature, its life-span will double.The omen that cooling blower damages is that the fan bearing noise raises, and still raises gradually although radiator has cleaned radiator temperature.When these omens occurring, should in time change cooling blower.
The omen that the cabinet blower fan damages is that the fan bearing noise raises, and temperature raises in the cabinet, when these omens occurring, even should change the cabinet blower fan.
The heating panel of heat exchanger is because long laying dust can make radiating efficiency reduce, so it is (different according to environment every two years should to carry out one-time dedusting, this cycle should shorten by actual conditions), use the fin of compressed air (drying) the purging radiator of cleaning during dedusting, use simultaneously dust catcher at air outlet slit place absorbing dust.
When abnormal sound or temperaturing lifting abnormality appear in the cooling fan motor of heat exchanger, should pull down motor and safeguard.
The utility model is compared and existing wind-force generating converter, and is easy for installation, uses simply, can be according to automatic amount of cooling water or the intensification amount of regulating wind-driven generator of the needs of wind-driven generator.
