Abstract
An air separation high-pressure oxygen pump remote system comprises a high-pressure oxygen pump, an oxygen pump return valve and a motor frequency converter. The oxygen pump return valve is a solenoid valve and is arranged in a high-pressure oxygen pump return throttle pipe, and the control end of the solenoid valve is connected with the input end of a remote controller through an A/D signal converter. The input end of the motor frequency converter is connected with the output end of the remote controller, and the output end of the motor frequency converter is electrically connected with a control circuit of a high-pressure oxygen pump motor. A displayer is arranged on the remote controller. According to the system, workers observe data through a display screen and adjust the rotation speed of the high-pressure oxygen pump motor, so that the oxygen pump return valve is closed completely, the motor power consumption is reduced, complex work that workers are required to perform adjustment on site in the past is changed, the efficient work of the high-pressure oxygen pump is guaranteed, and the power consumption is reduced.
Description
Technical field
The utility model relates to hyperbaric oxygen apparatus for controlling pump, particularly a kind of empty point hyperbaric oxygen pump remote system.
Background technique
Space division product pressurization is the empty point indispensable post equipment of low temperature separation unit.After air separation facility treatment product oxygen need pressurize, be supplied to follow-up system device to use.After interior compression sky point directly pressurizes product liquid oxygen, then gasify to normal temperature via main heat exchanger heat exchange, be supplied to follow-up system device to use.Hyperbaric oxygen pump is the in the situation that of normal production load and low-load, reflux valve has certain aperture, highly pressurised liquid backflow throttling meeting produces to a certain degree vibration and backflow spool is had to erosion, and vibration also causes the frequent breakage of motor bearings, and need staff to adjust to scene, the power consumption of efficient operation state is large.
Model utility content
The utility model object is to design a kind of hyperbaric oxygen pump tele-control system, makes oxygen pump reflux valve reduce operating cost, convenience easy to maintenance.
For achieving the above object, the technical solution of the utility model is:
A kind of empty point hyperbaric oxygen pump remote system, comprising: hyperbaric oxygen pump, is provided with backflow throttle pipe on it; Oxygen pump reflux valve, it is arranged in the pipeline of described hyperbaric oxygen pump reflux throttle pipe, and it is solenoid valve, and the control end of this solenoid valve is connected to the input end of remote controllers by A/D signal adapter; Motor inverter, its input end is connected with the output terminal of remote controllers, and the control loop of motor inverter output terminal and described hyperbaric oxygen pump motor is electrically connected.
Further remote controllers are provided with display device.
The beneficial effects of the utility model:
The utility model is in the time of hyperbaric oxygen pump work, judge the rotating speed of hyperbaric oxygen pump motor by the aperture of oxygen pump reflux valve, with the frequency of remote controllers control motor inverter, change the rotating speed of hyperbaric oxygen pump motor, finally make oxygen pump reflux valve close completely, reduce the power consumption of motor, change and need in the past people to arrive the miscellaneous works such as on-the-spot adjustment, guarantee that hyperbaric oxygen pump efficient operation has reduced power consumption.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
As shown in Figure 1, sky of the present utility model divides hyperbaric oxygen pump remote system, comprising: hyperbaric oxygen pump 1, is provided with backflow throttling pipeline on it; Oxygen pump reflux valve 3, it is arranged in the pipeline of described hyperbaric oxygen pump reflux throttle pipe, and it is solenoid valve, and the control end of this solenoid valve is connected to the input end of remote controllers 4 by A/D signal adapter 5; Motor inverter 2, its input end is connected with the output terminal of remote controllers 4, and the control loop of motor inverter 2 output terminals and described hyperbaric oxygen pump 1 motor is electrically connected; Described remote controllers are provided with display device 401.
In the time that hyperbaric oxygen pump 1 is worked, the control end of oxygen pump reflux valve 3, by cable 100, aperture is transferred to A/D signal adapter 5 with electrical signal form, via A/D signal adapter 5, electrical signal is converted into digital signal and transfers to remote controllers 4 by cable 100, staff checks digital signal content by display screen 401, adjust loop 200 by remote controllers 4, change the frequency of motor inverter 2 with this, the rotating speed that regulates hyperbaric oxygen pump 1 motor, finally makes oxygen pump reflux valve 3 in buttoned-up status.
When working, hyperbaric oxygen pump 1 judges the rotating speed of hyperbaric oxygen pump 1 by the aperture of oxygen pump reflux valve 3, control the frequency of motor inverter 2 with remote controllers 4, change the rotating speed of hyperbaric oxygen pump 1 motor, finally make oxygen pump reflux valve 3 in closing completely, reach the power consumption that reduces motor, change and need in the past people to arrive the miscellaneous works such as on-the-spot adjustment, guarantee that hyperbaric oxygen pump efficient operation has reduced power consumption.
