The detection device is characterized by comprising a vacuum pump, an isolating valve, a vacuum gauge and an air cylinder mounted in a corrugated pipe, wherein the air cylinder is connected with a fast port; the fast port is communicated with the internal corrugated pipe; an exhaust pipe of the vacuum pump is connected with the fast port; and the isolating valve and the vacuum gauge are mounted on the exhaust pipe between the vacuum pump and the fast port. A detection method comprises the steps as follows: A, connection of the corrugated pipe and the vacuum pump; B, lengthening of the corrugated pipe; C, vacuum pumping and D, numeric calculation. Compared with the prior art, the detection device and the detection method for the seal corrugated sleeve have the advantages as follows: with the adoption of the device and the method, a tiny leakage degree of the corrugated pipe can be detected and verified, and the novel detection device and the detection method are provided for maintenance under a highly clean aseptic condition.
Description
?
Technical field
The present invention relates to a kind of freeze-drier of pharmaceutical industry, relate in particular to a kind of pick-up unit and detection method that seals radiation fins.
Background technology
At present, in pharmaceuticals industry, relate to a lot of packoffs, particularly in aseptic pharmacy procedure, for moving component, such as the push rod of hydraulic jack, the push rod of cylinder, the screw rod of motor all needs to be isolated with shrinkable ripple sheath, to avoid moving lever to occur the risk that oil leak or fine particle come off in telescopic process.Ripple sheath can avoid the wear debris of hydraulic oil, industrial pressurized air, screw rod to be diffused in production run.
In current production run, because corrugated tube is that very frivolous stainless steel or tetrafluoroethene produced, therefore, cannot bear pressure, therefore inflate leak detecting and cannot realize, and precision is not high yet.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, provides a kind of pick-up unit and detection method that seals radiation fins.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of pick-up unit that seals radiation fins, it is characterized in that: comprise vacuum pump, isolation valve, vacuum meter and the cylinder of corrugated tube is installed, described cylinder connects a fast interface, this fast interface is communicated with inner corrugated tube, the exhaust tube of described vacuum pump is connected with fast interface, and described isolation valve and vacuum meter are installed on the exhaust tube between vacuum pump and fast interface.
Described cylinder can be substituted by oil cylinder or motor.
Another object of the present invention realizes by following technical scheme: a kind of detection method that seals radiation fins, is characterized in that: comprise the following steps:
A, connection corrugated tube and vacuum pump: a fast connection interface is set in the junction of corrugated tube, the exhaust tube of vacuum pump is connected on corrugated tube;
B, elongate corrugated tube: by the cylinder of corrugated tube is installed, corrugated tube is elongated to the longest position, the position of volume maximum namely, and calculate the volume V of bellows interior;
C, vacuumize: open vacuum pump and isolation valve, it is vacuumized, until vacuum reaches in 10Pa, and keep about 10 minutes, until inside does not have steam to extract out, then close vacuum separation valve, observe vacuum meter, write down vacuum value P1 now; After 30 minutes, write down vacuum value P2 now;
D, numerical operation: this numerical value is carried out to computing, in automatic equipment, can read PLC controller or computing is carried out in other intelligent controller inside to this numerical value, computing formula is as follows:
Slip Lr=V* (P2-P1)/T unit (Pa*L/s)
This numerical value can be tested three times, finally data is filed, and in the detection validation in later stage, repeats above mode, if in corrugated tube internal leakage rate higher than this numerical value, so, can judge that inner existence leak.
The present invention's advantage is compared with prior art: adopt device and method of the present invention, the trickle leak degree of energy detection validation corrugated tube, for new pick-up unit and the method that provide is provided under the gnotobasis of high cleaning.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of pick-up unit that seals radiation fins, it is characterized in that: comprise vacuum pump 1, isolation valve 2, vacuum meter 3 and the cylinder 4 of corrugated tube is installed, the described cylinder 4 that corrugated tube 7 is installed connects a fast interface 5, this fast interface 5 is communicated with inner corrugated tube 7, the exhaust tube 6 of described vacuum pump 1 is connected with fast interface 5, and described isolation valve 2 and vacuum meter 3 are installed on the exhaust tube 6 between vacuum pump 1 and fast interface 5.
A detection method that seals radiation fins, is characterized in that: comprise the following steps:

B, elongate corrugated tube: by the cylinder 4 of corrugated tube is installed, corrugated tube 7 is elongated to the longest position, the position of volume maximum namely, and calculate the volume V of corrugated tube 7 inside;
C, vacuumize: open vacuum pump 1 and isolation valve 2, it is vacuumized, until vacuum reaches in 10Pa, and keep about 10 minutes, until inside does not have steam to extract out, then close vacuum separation valve 2, observe vacuum meter 3, write down vacuum value P1 now; After 30 minutes, write down vacuum value P2 now;
D, numerical operation: this numerical value is carried out to computing, in automatic equipment, can read PLC controller or computing is carried out in other intelligent controller inside to this numerical value, computing formula is as follows:
Slip Lr=V* (P2-P1)/T unit (Pa*L/s)
This numerical value can be tested three times, finally data is filed, and in the detection validation in later stage, repeats above mode, if in corrugated tube internal leakage rate higher than this numerical value, so, can judge that inner existence leak.
