Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Embodiment.
As shown in Figure 2, a kind of constant temperature water tank is by casing 1, be located at heating tube 2, the temperature sensor 3 in the said casing 1 and be located at said casing 1 outer control system and form; Said control system comprises heating controller 51 and PLC Programmable Logic Controller 52; Said heating tube 2 is electrically connected with said control system respectively with said temperature sensor 3; Said casing 1 is divided into main water box 12 and time water tank 13 by a dividing plate 11, and is interconnected through a rising pipe 6 and a water inlet pipe 7; Said water inlet pipe 7 is communicated with said main water box 12 bottoms, and the centre is provided with a water pump 8; Said rising pipe 6 is communicated with said main water box 12 tops; Said PLC Programmable Logic Controller 52 is through the said heating tube of heating controller 51 controls 2, said temperature sensor 3 and said water pump 8.Wherein, be provided with a motor-operated control valve 9 in the middle of the said rising pipe 6, and by said PLC Programmable Logic Controller 52 controls; Said heating tube 2 is located in said water tank 13; Said temperature sensor 3 is located in the said main water box 12; For fear of casing get rusty and outside surface attractive in appearance, said casing 1 is a stainless steel, and outside surface is coated with the static baking vanish.
Adopt the principle of work of a kind of constant temperature water tank of present technique scheme to be: as shown in Figure 2; At first water is stored in main water box 12 and time water tank 13 after being heated to design temperature through heating tube 2; Cable under test is put into main water box 12; When the water natural temperature in the main water box 12 is cooled to this temperature when following, detected by temperature sensor 3, detection signal is transferred to heating controller 51; Passing to PLC Programmable Logic Controller 52 through conversion then; PLC Programmable Logic Controller 52 is commanded corresponding electric topworks to open operation valve 9 and is made in the water part inflow time water tank 13 in the main water box 12, and while PLC Programmable Logic Controller 52 orders about 2 pairs water tanks of heating controller 51 commander's heating tubes, 13 interior water and begins heating, when water is heated certain hour; The corresponding electric topworks of PLC Programmable Logic Controller 52 commanders opens water pump 8, and it is squeezed into the hot water in the inferior water tank 13 in the main water box 12.Because the mouth of pipe of water inlet pipe 7 is bottoms of being located at water main 12; Hot water is that the bottom from main water box 12 is driven into; The principle that is inversely proportional to temperature according to the density of water; Add heat hydraulic pressure from water inlet pipe 7; The water at low temperature that is positioned at main water box 12 tops can be sunk rapidly and evenly mix from water inlet pipe hot water, when the water temperature when temperature sensor 3 detects main water box 12 in reaches design temperature, again signal is transferred to PLC Programmable Logic Controller 52 and orders about heating controller 51 and command heating tubes 2 to stop to heat.So circulation can make the water in the main water box 12 remain at the design temperature state.
In addition, when cable under test need detect insulation values and withstand voltage under different water temperatures, only need on heating controller 51, to reset the temperature that needs and get final product, its course of work is the same, repeats no more at this.
Pass through technique scheme; The utility model is through being divided into said control system heating controller 51 and PLC Programmable Logic Controller 52; Said heating tube 2 is electrically connected with said heating controller 51 respectively with said temperature sensor 3; Said casing 1 is divided into main water box 12 and time water tank 13 by a dividing plate 11, and is interconnected through a rising pipe 6 and a water inlet pipe 7; Said water inlet pipe 7 is communicated with said main water box 12 bottoms, and the centre is provided with a water pump 8; Said PLC Programmable Logic Controller 52 is through the said heating tube of heating controller 51 controls 2, said temperature sensor 3 and said water pump 8, thereby reached simple in structure, reasonable in design, work is sensitive, hot and cold water is mixed and the purpose of energy-conserving and environment-protective rapidly.
