Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
the first embodiment is as follows:
As shown in fig. 1, a detection apparatus for mechanical sealing includes a leak detector 1, a first waste liquid tank 2, a second waste liquid tank 3, and a control terminal. The leak detector 1 is provided with an input port 7, an output port 8 and an overflow port 9, the input port 7 is connected with a mechanical seal through an input pipe 10, the height of the input port 7 is lower than that of the mechanical seal, the mechanical seal has little leakage during normal operation, and leaked liquid flows into the leak detector 1 under the action of gravity.
The inside level gauge that is used for detecting first liquid level and second liquid level that is equipped with of leak detector 1, and first liquid level corresponds delivery outlet 8 and sets up, and the second liquid level corresponds overflow outlet 9 and sets up, first liquid level is leaked a little by mechanical seal in normal during operation and is formed, and when mechanical seal damaged, liquid can leak rapidly, accumulates a large amount of liquid in leak detector 1 rapidly and forms the second liquid level, consequently, overflow outlet 9's position height should be higher than delivery outlet 8. In this embodiment, the input port 7 and the overflow port 9 are both located at the top of the leak detector 1, and the output port 8 is located at the bottom of the leak detector 1.
Meanwhile, the output port 8 is connected with the first waste liquid tank 2 through the first pipeline 11, the first pipeline 11 is provided with the electromagnetic valve 4 for controlling the first pipeline 11 to be opened or closed, the first waste liquid tank 2 is connected with the vacuum pump 5, and the inside of the first waste liquid tank 2 is ensured to be in a negative pressure state so as to accelerate the flow rate of the liquid flowing to the first waste liquid tank 2. And a water drop separator 6 is arranged between the first waste liquid tank 2 and the vacuum pump 5. The overflow outlet 9 is connected to the second waste tank 3 via a second line 12. Meanwhile, the liquid level meter and the electromagnetic valve 4 are respectively and electrically connected with a control terminal, and the control terminal is electrically connected with an alarm.
When mechanical seal normally works, first pipeline 11 is in a closed state, and the liquid that leaks flows into leak detector 1 under the action of gravity, and when the liquid in leak detector 1 accumulated first liquid level, the level gauge transmitted the signal to control terminal, and solenoid valve 4 switched on, and first pipeline 11 was in an open state, and the liquid in leak detector 1 flowed into first waste liquid case 2 under the negative pressure effect. When mechanical seal damaged, liquid leaked rapidly, and the second liquid level is accumulated rapidly to the liquid in the leak detector 1, and the level gauge transmits signal to control terminal, and solenoid valve 4 switches on, and partly liquid flows into first waste liquid case 2 under the negative pressure effect, and simultaneously, there is water pressure in the mechanical seal, and another part liquid flows into second waste liquid case 3 through overflow mouth 9 under the water pressure effect, and simultaneously, the alarm is opened, reminds the staff to overhaul.
In other exemplary embodiments, at least 2 leak detectors 1 are provided, and at least 2 leak detectors 1 are independent of one another.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
