Abstract
The utility model discloses a centrifugal pump air-tightness test device which is connected with a flange, which comprises the components of: an air source, a decompression valve, a switch valve and a sealing test clamp. The sealing test clamp comprises the components of: a mounting chassis, a sealing cylinder, a cylinder cover, a pipe joint and a steel wire thread sleeve. The mounting chassis is used for connecting with a centrifugal pump. For facilitating repeated detachment, the mounting chassis is also provided with a screw thread sleeve. The centrifugal pump air-tightness test device has a simple structure and can determine whether leakage of a centrifugal pump exists. The centrifugal pump air-tightness test device quickly and accurately determines whether sealing at connection part of the centrifugal pump housing is qualified. Additionally, replacement of a clamp is required for the centrifugal pump which is connected through a flange and has a different connector.
Description
Technical field

Brief description of the drawings:
Fig. 1 is sealing test schematic diagram of the present utility model.
Fig. 2 is sealing test fixture figure of the present utility model.
Fig. 3 is that centrifugal pump that certain ring flange of the present utility model connects is installed in sealing test fixture and schemes.
Embodiment
Below by embodiment, the utility model is described in further detail.Refer to Fig. 1 to Fig. 3.
A kind of centrifugal pump air seal proving installation, comprise source of the gas 1, reduction valve 2, switch valve 3, tensimeter 4, sealing clamp 5, source of the gas 1 is connected with reduction valve 2, reduction valve 2 other ends are connected with switch valve 3, switch valve 3 is connected with sealing clamp 5, between switch valve 3 and sealing clamp 5, tensimeter 4 is set.
Described sealing clamp comprises installation chassis 501, is arranged on the sealing bore 502 on installation chassis 501, and sealing bore 502 tops are provided with cover 503, and sealing bore 502 sides are provided with pipe adapter 504, and the bottom of installation chassis 501 is provided with steel-wire screw-socket 505.
The centrifugal pump sealing test requirement connecting according to ring flange and ring flange connect the sealing test principle of centrifugal pump, when gas enters switch valve 3 through reduction valve 2, in order accurately to find out the pressure size that enters centrifugal pump gas, at the rear special tensimeter 4 of having installed of switch valve 3, the pressure that guarantee enters centrifugal pump is required pressure; For clamping and the repeatedly requirement of dismounting, on installation chassis 501, there is the pipe adapter the same with centrifugal pump 504, on installation chassis, steel-wire screw-socket 505 is housed simultaneously.
Sealing test device of the present utility model, when test centrifugal pump gas seal property, step is as follows:
1) according to the requirement of test, the centrifugal pump that ring flange is connected is installed in sealing test fixture, with screw fastening;
2) open successively source of the gas, reduction valve and switch valve;
3), according to the pressure requirement of test, regulate the pressure of reduction valve to the pressure of this test;
4) method to centrifugal pump employing development or spike.
5) when in centrifugal pump when gassy, if centrifugal pump shell surface is unchanged in official hour, illustrate that sealing is intact.
6), after having tested, turn off successively switch valve, reduction valve.
7) remove centrifugal pump.
