Abstract
The invention belongs to the technical field of refrigeration and relates to a pressure maintaining method for a filament pipe evaporator. According to the pressure maintaining method for the filament pipe evaporator, after a filament pipe evaporator pipe is filled with nitrogen and is placed for 24 hours, a pressure maintaining test is conducted through a testing device. The testing device is a tire pressure gun with a needle. The following steps are included that (1) a produced liquid-inlet-outlet pipeline of the filament pipe evaporator is sealed by a rubber plug; (2) the tire pressure gun with the needle is inserted into the rubber plug, the filament pipe evaporator is filled with the nitrogen, the nitrogen filling pressure is controlled to 0.23+/-0.03 mpa, and then the needle is pulled out; and (3) after the filament pipe evaporator filled with the 0.23+/-0.03 mpa pressure nitrogen is placed for 24 hours, the tire pressure gun with the needle is inserted into the rubber plug again till the pressure value in the filament pipe evaporator pipeline is measured. The qualified effect is achieved when the measured pressure value in the step (3) is 0.23+/-0.03 mpa, and the testing method is simple and easy to popularize.

A kind of wire-tube evaporator pressurize method, comprises the steps：
1）The liquid in-out pipeline of the wire-tube evaporator for having produced is sealed with rubber plug；
2）Nitrogen is filled with using the insertion rubber plug of the tire pressure gun with syringe needle toward in wire-tube evaporator, be filled with the pressure control of nitrogen
Then system extracts syringe needle in 0.23 ± 0.03MPa；
3）Be filled with 0.23 ± 0.03MPa nitrogen pressures wire-tube evaporator place 24 hours after, again will with syringe needle tire pressure
In rifle insertion rubber plug in the wire-tube evaporator pipe measured pressure value.
Described step 3）The pressure value of middle measurement is qualified in 0.23 ± 0.03MPa.
Above content is with reference to specific preferred embodiment further description made for the present invention, it is impossible to assert
The present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of without departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
