Abstract
The utility model discloses a circulating water temperature controlling device of a vacuum unit, which comprises a water injecting tank and a gas sucking device, wherein the water injecting tank is connected with a three way through a pipeline; the three way is respectively connected with a water supply pipe and a heat exchange pipe; a first control valve is arranged on the water supplying pipe; a second control valve is arranged on the heat exchange pipe; the water supply pipe and the heat exchange pipe are respectively connected with a mixing water tank; a water outlet pipe is arranged on the mixing water tank; the water outlet pipe is connected with the gas sucking device; the heat exchange pipe penetrates in the casing of a heat exchanger; and the heat exchanger is connected with a water cooling unit through a circulating pipe. The first control valve and the second control valve are electromagnetic valves. A temperature sensor is arranged on the water outlet pipe. The temperature sensor, the first control valve and the second control valve are respectively connected with a controller through conducting wires. The utility model has the advantages that the circulating water of the vacuum equipment can be ensured to have suitable temperature; the vacuum degree of the vacuum pump is not affected; and the temperature of the circulating water can be automatically adjusted, and the like.
Description
Technical field
The utility model relates to a kind of vacuum equipment, specifically a kind of vacuum unit circulating water temperature control gear.
Background technique
Nash hytor and water-jet vacuum pump, the corresponding corresponding ultimate vacuum of corresponding water temperature, its ultimate pressure is exactly a relevant temperature water saturation vapor pressure, when equipment operation, because multiple factors such as temperature all may cause circulating water temperature to raise, and degree of vacuum is affected.
Summary of the invention
The purpose of this utility model provides a kind of vacuum unit circulating water temperature control gear, and it can guarantee that the circulating water of vacuum equipment keeps suitable temperature, does not influence the degree of vacuum of vacuum pump.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise jetting case and air ejector, the jetting case is connected with threeway by pipeline, and threeway is connected with heat exchanging tube with water pipe respectively, and first control valve is installed on the water pipe, second control valve is installed on the heat exchanging tube, water pipe all is connected with mixing tank with heat exchanging tube, and mixing tank is provided with outlet pipe, and outlet pipe is connected with air ejector, heat exchanging tube process in the housing of heat exchanger, heat exchanger is connected with handpiece Water Chilling Units by Circulation pipe.Described first control valve and second control valve all are solenoid valves, mounting temperature sensor on the outlet pipe, and temperature transducer, first control valve and second control valve all are connected with controller by lead.
Advantage of the present utility model is: the circulating water that can guarantee vacuum equipment keeps suitable temperature, does not influence the degree of vacuum of vacuum pump.Circulating water temperature can be regulated etc. automatically.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Vacuum unit circulating water temperature control gear described in the utility model comprises jetting case 1 and air ejector 2, jetting case 1 is connected with threeway 3 by pipeline, threeway 3 is connected with heat exchanging tube 5 with water pipe 4 respectively, first control valve 14 is installed on the water pipe 4, second control valve 11 is installed on the heat exchanging tube 5, water pipe 4 all is connected with mixing tank 6 with heat exchanging tube 5, mixing tank 6 is provided with outlet pipe 7, outlet pipe 7 is connected with air ejector 2, heat exchanging tube 5 process in the housing of heat exchanger 8, heat exchanger 8 is connected with handpiece Water Chilling Units 10 by Circulation pipe 9.The cryogenic refrigeration liquid that handpiece Water Chilling Units 10 produces enters heat exchanger 8 through Circulation pipe 9, to the processing of lowering the temperature of the circulating water of the heat exchanger 8 of flowing through along heat exchanging tube 5, circulating water after the cooling with together enter mixing tank 6 without circulating water cooled and mix, reach the purpose of cooling, guarantee that the circulating water that enters air ejector 2 keeps lower water temperature, does not influence degree of vacuum.Because in most cases the temperature of circulating water does not have rising by a relatively large margin, therefore the cooling that only needs circulating water is carried out among a small circle gets final product, if whole circulating waters are all fed heat exchanging tube 5, will reduce to suitable temperature by in heat exchange very short time, need frequent opening and closing handpiece Water Chilling Units 10 in the equipment operation, have a strong impact on the working life of handpiece Water Chilling Units 10, therefore need be with behind the part circulating water cooling, mix with circulating water cooled not, reach suitable temperature and supply with air ejector 2, in running order for a long time to guarantee handpiece Water Chilling Units 10, the temperature that the staff can regulate circulating water by the valve opening of controlling first control valve 14 and second control valve 11, described first control valve 14 and second control valve 11 can adopt manually-operated gate, are manually controlled by the staff.
The utility model is in order to realize the temperature of automatic control circle water, can be by the following technical solutions: described first control valve 14 and second control valve 11 all be solenoid valves, mounting temperature sensor 12 on the outlet pipe 7, and temperature transducer 12, first control valve 14 and second control valve 11 all are connected with controller 13 by lead.Temperature transducer 12 can pass to controller 13 with the temperature data of circulating waters in the outlet pipe 7, and controller 13 is according to circumstances controlled the temperature that the valve opening of first control valve 14 and second control valve 11 is regulated circulating water.
