As further improvement in the technical proposal, the flow transmitter of described parallel connection is a vortex flow transmitter.
The beneficial effects of the utility model are: the utility model adopts the variable frequency control of circulation main pump and being used in combination of bypass valve, can conveniently realize the control of the be in harmonious proportion constant current amount of closed circuit medium flow, satisfies the requirement of converter valve water-cooling system test.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is that the utility model is formed structural representation.
Embodiment
With reference to Fig. 1, the constant current amount water supply circulating cooling system that a kind of closed flow of the present utility model is adjustable, comprise the circulation main pump 1, converter valve access port 2, cooling tower 3 and the surge tank 4 that connect into the loop by pipeline, have access to the flow transmitter 5 that is connected in parallel between described circulation main pump 1 and the converter valve access port 2,6, the endpiece of the endpiece of described circulation main pump 1 and converter valve access port 2 is connected to bypass 7, and described bypass is provided with flow transmitter 8 and valve 9.The utility model adopts the variable frequency control of circulation main pump and being used in combination of bypass valve, can conveniently realize the control of the be in harmonious proportion constant current amount of closed circuit medium flow, satisfies the requirement of converter valve water-cooling system test.
As preferred implementation, described circulation main pump 1 is the variable-frequency motor pump.Certainly, also may be selected to this lower power frequency motor, match frequency converter in addition.
As preferred implementation, the flow transmitter 5,6 of described parallel connection is a vortex flow transmitter.
As preferably, the utility model is separately installed with operation valve 51,61 before transmitter 5,6.
As preferably, the measurement range of above-mentioned flow transmitter 5,6 is respectively: 100-500l/m and 0-100l/m, and valve 9 is a ball valve.Flow control mode of the present utility model is divided into four kinds.Be respectively big flow converting operation pattern, low discharge converting operation pattern, big flow power frequency operation pattern and low discharge power frequency operation pattern.
1) big flow converting operation pattern: (range of control of this flow transmitter is: 100-500l/m) to select to detect flow transmitter 5, manual-lock operation valve 61, main circulation pump (the minimum operation frequency setting is 25HZ) advances the valve target flow according to what set, by PID operation result variable frequency starting.Concrete operations are: the first, on man-machine interface, select to detect flow transmitter 8, and closed control valve 61; The second, target setting flow (100-500l/m); The 3rd, press " variable mode " key.After finishing above operation, water-cooling system will be closed to spacing back variable frequency starting in bypass valve 9 electrically operated valve autompulse formulas.Main pump carries out flow control according to target flow by the PID computing.
2) low discharge converting operation pattern.Because the motor of main circulation pump is the non-frequency motor, main pump is chosen in operation (according to the working control requirement, can set this running frequency on man-machine interface) under that configure and the suitable lower frequency, with the range of control (0-100l/m) that satisfies low discharge.Concrete operations are: the first, select flow transmitter 5, manual-lock operation valve 61; The second, target setting flow (0-100l/m), the 3rd presses " variable mode " key.After finishing above operation, water-cooling system will be opened to spacing back variable frequency starting in bypass valve 9 electronic ball autovalve pulseds.Main circulation pump advances valve target flow (0-100l/m) and will be controlled by electrically operated valve 9 after operation under the selected frequency.
3) big flow power frequency operation pattern: be under the situation of main circulation pump power frequency operation and select flow transmitter 5 transmitters to participate in the control computing, carry out flow regulation to reach the purpose of constant flux control by by-pass valve control 9.This pattern is the auxiliary operational mode under the situation of big flow variable mode inefficacy (frequency converter failure).Concrete operations are: the first, selecting flow transmitter 5, manual-lock operation valve 61; The second, set the valve target flow; The 3rd, press " power frequency pattern ".After finishing above operation, water-cooling system will be opened to spacing back at bypass valve 9 and start.Main circulation pump motor power frequency 50HZ operation, consistent when electrically operated valve valve 9 is controlled with the low discharge variable mode.
4) low discharge power frequency operation pattern.This pattern is under the situation of main circulation pump power frequency operation and selects flow transmitter 5 transmitters to participate in the control computing, carries out flow regulation to reach the purpose of constant flux control by control electrically operated valve valve 9.This pattern is the auxiliary operational mode under the situation of low discharge variable mode inefficacy (frequency converter failure).Concrete operations are: the first, selecting flow transmitter 5, manual-lock operation valve 51; The second, set the valve target flow; The 3rd, press " power frequency pattern ".After finishing above operation, water-cooling system will be opened to spacing back at bypass valve 9 and start.Main circulation pump motor power frequency 50HZ operation, consistent when valve 9 is controlled with the low discharge variable mode.
