Abstract
The invention discloses a cavitation resistance device capable of preventing a cryopump to suck air. The device comprises a cryopump pool provided with the cryopump and a liquid level detection device; and the output end of the liquid level detection device is connected with a control device which is used to control the cryopump to operate. The liquid level detection device is arranged in the cryopump pool of the cavitation resistance device of the invention so that when the liquid level of the cryopump pool is lower than a set value, the liquid level detection device gives an alarming signal to control the device to stop the cryopump, thus effectively preventing the impeller damage caused by the reason that the cryopump sucks air and greatly enhancing the safety of the cryopump.
Description
Technical field
The present invention relates to and prevent the empty cavitation resistance device of pump suction, refer more particularly to and prevent the empty cavitation resistance device of cryopump suction.
Background technique
At present, countries in the world are trying to explore to use LNG Liquefied natural gas to replace vapour, the diesel oil fuel as automobile, and LNGV (liquefied natural gas vehicle) is under test, and its technology reaches its maturity.When filling LNG Liquefied natural gas to vehicle, need use the higher cryopump of price, be mainly used in the raising filling pressure.In the actual using process, the Security of cryopump is relatively poor, usually can be low excessively because of the liquid level in the cryopump pond, make that the cryopump suction is empty and cause impeller to damage, and cause heavy economic losses.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of cryopump that prevents to inhale empty cavitation resistance device.
For solving the problems of the technologies described above, the technical solution used in the present invention is: cavitation resistance device, comprise: be provided with the cryopump pond of cryopump, described cryopump also is provided with liquid level detection device in the pond, and the output terminal of this liquid level detection device links to each other with the control gear of control cryopump running.
Described liquid level detection device is a level meter.
The invention has the beneficial effects as follows: owing in the cryopump pond, be provided with liquid level detection device, when the liquid level in the cryopump pond is lower than setting value, liquid level detection device is sent alarm signal, control gear is closed down cryopump, thereby prevented the impeller damage that cryopump causes because of inhaling sky effectively, the Security that has improved cryopump greatly.
