3 terms and definitions
The following definitions and definitions of the following definitions and definitions apply to this document in GB/T 30300-2013.
3.1
Membrane housing membranehousing
For holding the membrane element, can carry a certain pressure of the cylindrical shell.
[GB/T 30300-2013, definition 3.1]
3.2
Cyclic pressure cyclic pressureure
The reciprocating pressure is applied to the interior of the separation membrane housing from the minimum pressure to the design pressure and then to the minimum pressure.
3.3
Cyclic pressure frequency cyclic pressureurefrequency
The number of periodic changes in the separation of the membrane shell from the minimum pressure to the design pressure and then to the minimum pressure.
3.4
Leakage
Separate film shell under the action of water pressure, the test medium through the cracks and porosity spread to the shell, with bearing parts and sealing parts, etc.
Other than the process.
3.5
The highest exhaust point of thehighestexhaustpoint
The highest point of the high-pressure pipe connecting the separation membrane housing can effectively discharge the air mixed in the test system.
3.6
Minimum pressure minimumpressure
The minimum pressure is the minimum pressure required during the cyclic pressure test, which is not greater than 20% of the design pressure and 0.27 MPa
The smaller of the two.
