Description
Technical field
The utility model relates to a kind of steady temperature device of voltage stabilizing of maritime platform blower fan.
Background technique
On the long-term operation Yu Haiyang of offshore platform, exploit simultaneously and run oil, equipment on board is all powerful important drilling equipment, so the power of cabin generator is all larger.In cabin, equipment is very large to the demand of air quantity, and in cabin, the control of temperature is also most important to the ride quality of equipment simultaneously.When now design the air deliverability of blower fan be according to the institute of platform likely in working condition the ventilation of maximum require to choose, therefore blower fan is no matter under which kind of working condition, all move with unique rotating speed of design, there is the superfluous problem of wind-force in fan design now, cause the significant wastage of electric power energy, the uncontrollable fan operation of cabin temperature, exerts an influence greatly to the safety of life of equipment and ocean platform simultaneously.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, a kind of energy saving is provided, improves working life, increases the steady temperature device of voltage stabilizing of maritime platform blower fan of safety coefficient.
The purpose of this utility model is achieved through the following technical solutions: a kind of steady temperature device of voltage stabilizing of maritime platform blower fan, comprise two differential pressure switches and a thermal switch, two differential pressure switches are all connected with electric control box with a thermal switch, electric control box is connected with ventilation unit, and microcomputer and frequency variator are housed in electric control box.
Further improvement of the utility model is: ventilation unit is blower fan.
Further improvement of the utility model is: two differential pressure switches are used for responding to and compare the inside and outside pressure difference in cabin.
Further improvement of the utility model is: thermal switch is for responding to the temperature in cabin.
Further improvement of the utility model is: the working principle of the steady temperature device of voltage stabilizing is: differential pressure switch is set, the external pressure difference of induction cabin inner air pressure and outside, and output switch amount signal; Set temperature switch, thermal switch is experienced engine room inside temperature, output switch amount signal; Two signals are given the microcomputer in electric control box by cable by switching value signal; Microcomputer, according to default compute mode, provides the control loop of control signal to frequency variator step by step; Control loop is transported to ventilation unit after the output frequency of frequency variator power loop is only regulated, and controls the operation conditions of ventilation unit, controls cabin air pressure and temperature.
The utility model compared with prior art has the following advantages: the utility model is responded to respectively the temperature in pressure difference and the cabin inside and outside cabin by differential pressure switch and thermal switch, and control in real time the working condition of ventilation unit by electric control box, control in time the pressure and temperature in cabin, save the energy, work together the working life of having improved equipment, increased the safety in production coefficient of ocean platform.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-differential pressure switch, 2-thermal switch, 3-electric control box, 4-ventilation unit, 5-microcomputer, 6-frequency variator.
embodiment:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of mode of execution of the steady temperature device of voltage stabilizing of the utility model maritime platform blower fan, the steady temperature device of described voltage stabilizing comprises two differential pressure switches 1 and a thermal switch 2, two differential pressure switches 1 are all connected with electric control box 3 with a thermal switch 2, electric control box 3 is connected with ventilation unit 4, and microcomputer 5 and frequency variator 6 are housed in electric control box 3; Ventilation unit 4 is blower fan; Two differential pressure switches 1 are for responding to and comparing the pressure difference inside and outside cabin; Thermal switch 2 is for responding to the temperature in cabin.
The working principle of the steady temperature device of voltage stabilizing is: differential pressure switch 1 is set, the external pressure difference of induction cabin inner air pressure and outside, and output switch amount signal; Set temperature switch 2, thermal switch 2 is experienced engine room inside temperature, output switch amount signal; Two signals are given the microcomputer 5 in electric control box 3 by cable by switching value signal, microcomputer 5 is according to default compute mode, the control loop of control signal to frequency variator 6 is provided step by step, control loop is transported to ventilation unit 4 after the output frequency of frequency variator 6 power loops is only regulated, control the operation conditions of ventilation unit 4, control cabin air pressure and temperature.
When cabin internal pressure is during lower than setting value, pressure difference switch 1 moves, and when temperature reaches setting value, thermal switch 2 moves, two signals all by cable transmission to microcomputer 5, microcomputer 5 is exported to frequency variator 6, improves blower fan 4 rotating speeds; When cabin internal pressure is during higher than setting value, pressure difference switch 2 moves, and provides a switching signal, and switching signal is by cable transmission to microcomputer 5, and microcomputer 5 is exported to frequency variator 6, reduces the rotating speed of blower fan 4; When temperature in cabin is during higher than setting value, thermal switch 2 moves, and provides a switching signal, and switching signal is by cable transmission to microcomputer 5, and microcomputer 5 is exported to frequency variator 6, reduces the rotating speed of blower fan 4.
The utility model is responded to respectively the temperature in pressure difference and the cabin inside and outside cabin by differential pressure switch and thermal switch, and control in real time the working condition of ventilation unit by electric control box, control in time the pressure and temperature in cabin, save the energy, work together the working life of having improved equipment, increased the safety in production coefficient of ocean platform.
