Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, a kind of high pressure water-cooling frequency converter automatic water replenishing system, including water supply tank 1 and the electricity being attached thereto
Conductance detects table 2, and the water supply tank 1 is made using stainless steel, is connected with self-circulation system 3 on the water supply tank 1
With water charging system 4, the self-circulation system 3 includes filter 31, deionization tank 32, water pump 33 and the self-loopa being connected in series
Switch valve 34, the water inlet of the self-circulation system 3 are connected to the lower part of the water supply tank 1, the water outlet of the self-circulation system 3
Mouth is connected to the top of the water supply tank 1, and the water charging system 4 includes the total water compensating valve 41 being sequentially connected in series and parallel with one another
Several single line water charging systems 4, each single line water charging system 4 include the single line water compensating valve 42 being sequentially connected in series and single line frequency conversion
Device water tank 43, the self-circulation system 3, water charging system 4, water supply tank 1 and conductivity detection table 2 and a control system signal connect
Connect, the water charging system 4 can long term storage cooling water, and itself monitor, filtering deionization spare, moisturizing of protecting positive cooling water qualification
System 4 can the low benefit height of itself monitor Coolant-Level stop.
Preferably, the water inlet of the water charging system 4 can be connected directly between the lower part of the water supply tank 1, it can also
To be connected on the self-circulation system 3, and it is set between the self-loopa switch valve 34 and the water pump 33.
The course of work of the utility model is as follows: usually water supply tank 1 detects table 2 by conductivity and carries out conductivity self-test,
When conductivity is low signal be transmitted to control system (its be the prior art content, as by input signal sending control signal
PLC control panel), control system starts self-circulation system 3, opens self-loopa switch valve 34 and starts water pump 33 for water supply tank 1
In distilled water self-loopa carried out by filter 31 and deionization tank 32 to go deionization and impurity to improve conductivity cold to guarantee
But water is chronically at eligible state.When the low alarm of the Coolant-Level of frequency converter, as some single line frequency converter water tank 43 pass through it is low
Level gauge feedback signal opens total water compensating valve 41 and the corresponding single line of single line frequency converter water tank 43 to control system, control system
Water compensating valve 42 starts water pump 33, and water charging system 4 starts moisturizing, and moisturizing to required liquid level is by 43 high liquid level of single line frequency converter water tank
For feedback signal to control system, control system closes the corresponding single line water compensating valve 42 of single line frequency converter water tank 43 and total water compensating valve
41.The frequency converter of moisturizing as needed selects corresponding water supply valve, by the size of control valve, to adjust the water of moisturizing
Amount, moisturizing to setting value stop moisturizing.As frequency converter water tank all in high liquid level, conductivity in acceptability limit total water compensating valve 41,
All single line water compensating valves 42 and water pump 33 all stop working, and system is in armed state.
Using the above structure due to the utility model, it can be realized and give polyolefin A BB high-voltage frequency converter automatic on-line moisturizing,
And the conductivity and hydraulic pressure of the cooling water of injection are controlled, PE or big PP pelletizer drop amount or shutdown are avoided, avoids causing to production
Loss, prevents that the brings such as conductivity brought by manual operation is not high, liquid level is low are potential unplanned to stop from security standpoint completely
Vehicle risk；This system can also provide automatic water supplement operation simultaneously for more frequency converters simultaneously, without human intervention, greatly save
Cost of labor.Moisturizing is carried out using this system, scene does not have to packet powder, manpower and material resources waste is avoided, without clear
S6220 and K7010 suction line, subsidiary engine cooling water filter 31 do not have to dismounting cleaning, and centrifuge dripping device, which does not have to open, to be checked, subtract
Few 1,000,000 or more economic loss.
The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description
In the range of being covered with new patent.
