Background technology
In the modern industrial, usually need control, especially the cleaning machine water pump the heat that high power motor produces; Reach more than 40 degree if water temperature is too high; Will constitute harm to the seal member in the water lines, cause the thermo-oxidative ageing of these rubber components, sealing descends.If the too high cleaning agent that then can cause of supersonic wave cleaning machine coolant-temperature gage evaporates in addition, also need control water temperature.In food production, also there are the needs that a large amount of high-temperature products are cooled off fast, reach the Fast Packet reload request to make things convenient for product.Water-cooled is the circulatory system environment that has a wide range of applications but.
Shown in Figure 1 is the but circulatory system of external water-cooled of existing cleaning machine; This system is by an open type air-conditioning cooler bin 1; There is cooling condenser pipe 17 inside; It is through 2 control intake pumps 5 of the float in sidewall communicating pipe 9 and draining pump 6 work, the water pipe A3 that repeatedly kicks into and outlet pipe 4 be connected on the discharge outlet pipeline of operating water tank.Its operation principle is; Adopt two work water pumps of float-type control during work; Concrete principle is that the lever conductor switch that can connect intake pump A5 or draining pump 6 is arranged on the float 2, and intake pump A5 on-off circuit 7 is able to be communicated with when float 2 is positioned at the desired level of water below, intake pump A5 work; Water suction air-conditioning cooler bin 1 cooling that temperature in the operating water tank is higher; When float 2 was positioned at the desired level of water top, draining pump 6 on-off circuits 8 were able to be communicated with, and draining pump 6 work are sent the liquid that temperature is lower in the air-conditioning cooler bin 1 back to the operating water tank cooling.This mode can not effectively be controlled the operating water tank temperature, and water temperature also can ceaselessly circulate (only if closing the powered operation circuit) when low always, fails to give full play to cooling effect because of intake pump A5 and draining pump 6 alternations and has increased power consumption.
Summary of the invention
The purpose of the utility model provides the external water circulation system of a kind of closed, can give full play to cooling effect, reduces power consumption.
The utility model is realized above-mentioned purpose through following technical scheme; The external water circulation system of closed; A closed air-conditioning cooler bin is equipped with overflow valve and safety valve, is covered with condenser pipe in it, and closed air-conditioning cooler bin top is connected with operating water tank through return pipe; The bottom is connected with operating water tank through water inlet pipe B; And intake pump B is installed on the water inlet pipe B, is connected to temperature controller on the intake pump B, temperature controller connects the air conditioner temperature sensor that is equipped with on the water tank temperature sensor that is equipped with on the operating water tank and the closed air-conditioning cooler bin respectively through cable.
The utility model is the closed-loop control system through external air conditioner water circulatory system operation principle, according to the accurate control that the variation of environmental condition is realized ideal, adopts the seal cooler bin; Only use an intake pump job, utilize temperature controller to control the temperature range of intake pump work, reach the needs of efficient energy-saving operation; And substitutability easy to connect is strong; Can accurately control water temperature, energy-efficient, applied widely.

Among the figure: 1, air-conditioning cooler bin, 2, float, 3, water inlet pipe A, 4, outlet pipe, 5, intake pump A, 6, draining pump; 7, switch intake pump circuit, 8, switch draining pump circuit, 9, be communicated with organ pipe, 10, return pipe, 11, water inlet pipe B; 12, intake pump B, 13, air conditioner temperature sensor, 14, the water tank temperature sensor, 15, closed air-conditioning cooler bin, 16, cable; 17, condenser pipe, 18, temperature controller, 19, operating water tank, 20, overflow valve, 21, safety valve.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is described further at present; Referring to Fig. 2, the external water circulation system of closed, a closed air-conditioning cooler bin 15 is equipped with overflow valve 20 and safety valve 21; Be covered with condenser pipe 17 in it; Closed air-conditioning cooler bin 15 tops are connected with operating water tank 19 through return pipe 10, and the bottom is connected with operating water tank 19 through water inlet pipe B11, and on the water inlet pipe B11 intake pump B12 is installed; Intake pump B12 is connected to temperature controller 18, and temperature controller 18 connects the air conditioner temperature sensor 13 that is equipped with on the water tank temperature sensor that is equipped with on the operating water tank 19 14 and the closed air-conditioning cooler bin 15 respectively through cable 16.
Embodiment:The temperature controller 18 of the utility model selects for use 2 boilers to substitute with temperature controller; Model is LCP-WE77; Concrete operation principle is: worked according to operating water tank temperature control water inlet pump B12 by temperature controller 18; When the operating water tank temperature was higher than prescribed limit (as being set at 35 ℃), water tank temperature sensor 14 triggered and starts intake pump B12 automatically to 15 water supply of closed air-conditioning cooler bin, and closed air-conditioning cooler bin 15 is closeds; The cold water that internal temperature is lower has only through return pipe 10 and flows back to operating water tank 19, thereby reaches the cooling purpose.If closed air-conditioning cooler bin 15 water temperatures high (as being set at 25 ℃); Then sensor 13 triggers the intake pump B12 work of cutting off; (as being set at 20 ℃) air conditioner temperature sensor 13 stops intake pump B12 work when treating that closed air-conditioning cooler bin 15 is reduced to set point of temperature with water temperature, has so just improved cooling effectiveness.
Intake pump B12 can select according to closed air-conditioning cooler bin 15 volume size, and is generally unsuitable excessive, selects discharge capacity to get final product at the centrifugal pump of 20-50L/min.Also can suitably select the higher centrifugal pump of lift according to working environment, for example operating water tank 19 is bigger with closed air-conditioning cooler bin 15 position drops, can be according to the selection of the corresponding increasing lift of drop span.Based on security consideration; The scalable water temperature of the external water circulation system of the utility model closed is between 10 ℃ to 40 ℃; The pressure that can bear in the closed air-conditioning cooler bin 15 (is distinguished according to selected material specification difference is installed to some extent; Generally should between 150Bar-300Bar, get final product) through safety valve 21 and overflow valve 20 control pressure releases; The pressure of safety valve 21 is arranged in the safe range that closed air-conditioning cooler bin 15 can bear, and overflow valve 20 is selected bigger slightly getting final product according to selected intake pump B12 displacement size.
