Abstract
The utility model relates to a fluid constant temperature device used for precise processing machine tool, comprising a refrigerator, an electrical heating tube, an oil pump, pipeline, a liquid feed hole, a liquid discharge hole and an electric appliance control circuit which are all arranged in a housing. The utility model is characterized in that a combined heat exchanger with an internal layer and an external layer is arranged in the housing, the electrical heating tube is arranged on the internal layer, an evaporating pipe of the refrigerator is arranged on the external layer, and a closed channel for liquid flow is arranged in the heat exchanger. The utility model has the advantages of constant liquid temperature, precise processing of precise machine tool and convenient use.
Description
(1) technical field: the utility model belongs to the liquid constant temperature equipment of precision finishing machine adapted.
(2) background technology: precision finishing machine requires lubricating oil, hydraulic oil and the cutting fluid of lathe to keep constant temperature for guaranteeing machining accuracy, the at present domestic equipment that the independent cooling of liquid is arranged or heat up.And not for the liquid constant temperature equipment that can lower the temperature and can heat up of precision finishing machine special use.
(3) summary of the invention: the purpose of this utility model provides a kind of liquid constant temperature machine, and it can make liquid heat up automatically or cooling, thereby keeps constant temperature, guarantees machine finish.
The technical solution of the utility model is: be provided with refrigeration machine, electrothermal tube, oil pump, pipeline, liquid sucting port, liquid outlet and electrical apparatus control circuit in the casing of liquid constant temperature machine, it is characterized in that: be provided with unitized exchanger in the casing, heat exchanger has inside and outside two-layer, electrothermal tube is arranged on internal layer, the evaporation tube of refrigeration machine is arranged on skin, heat exchanger has pipeline to link to each other with liquid sucting port, liquid outlet respectively, is the close passage of liquid flow in the heat exchanger.Beneficial effect is: liquid heated up or cooling, thereby keep the machining accuracy of constant temperature assurance precision machine tool, and easy to use.
(4) description of drawings: Fig. 1 is a structural principle schematic diagram of the present utility model, and Fig. 2 is a schematic appearance of the present utility model, 1-casing among the figure, 2-refrigeration machine, 3-electrothermal tube, 4-oil pump, 5-pipeline, 6-liquid sucting port, 7-liquid outlet, 8-heat exchanger, 9-evaporation tube.
(5) specific embodiment:
Embodiment is referring to Fig. 1 Fig. 2, and the panel of casing (1) is provided with the temperature number and puts display, conversion turn-knob and four indicator lamps, and casing and heat exchanger (8) are to be made through machining by sheet material, and other each part is buied by market.During use, liquid sucting port (6) is connected with the liquid reserve tank of lathe with liquid outlet (7), during winter, the liquid temperature is low, will change turn-knob and place the intensification position, when the display temperature value is lower than design temperature, electrothermal tube (3) work, oil pump (4) drives liquid flow, is heated by electrothermal tube, until reaching design temperature.During summer, the conversion turn-knob places the cooling position, when the liquid temperature is high, and oil pump and refrigeration machine (2) running, heat in evaporation tube (9) absorption liquid is until reaching design temperature.Control circuit is handled above-mentioned action automatically, and indicator lamp is display working condition then.
Claims (1)
1. be provided with refrigeration machine (2), electrothermal tube (3), oil pump (4), pipeline (5), liquid sucting port (6), liquid outlet (7) and electrical control circuit in the casing of liquid constant temperature machine (1), it is characterized in that: be provided with unitized exchanger (8) in the casing, heat exchanger has inside and outside two-layer, electrothermal tube (3) is arranged on internal layer, the evaporation tube (9) of refrigeration machine (2) is arranged on skin, heat exchanger has pipeline to link to each other with liquid sucting port (6), liquid outlet (7) respectively, stops the close passage that flows for liquid in the heat exchanger.
