Abstract
The utility model relates to a single-stage pump hydrostatic test technical field provides a project organization for single-stage pump hydrostatic test very much, including the first apron that is used for sealed pump body import flange position and the third apron that is used for the second apron of the big terminal surface of sealed pump body screw thread and is used for sealed pump body export flange, be equipped with connecting rod lower extreme and second apron fixed connection, upper end and first apron swing joint, and the upper surface edge of second apron be the step structure of multistage outside-in gradual increase, connecting rod upper end threaded connection locking cap is equipped with the water injection hole on the third apron. This is novel to have solved and need a lot of bolts to realize the problem of revealing easily that sealed leads to among the prior art to step structure on the second apron, thereby the pump body that makes different models can all carry out hydrostatic test with this project organization, saves the cost, and work efficiency is high.
Description
Technical Field
The utility model relates to a single-stage pump hydrostatic test technical field provides a project organization for single-stage pump hydrostatic test very much.
Background
The existing single-stage pump body pressure test mode is that openings at different positions of a pump body are sealed by utilizing a plurality of sealing plates, only one opening is reserved for water filling, the last sealing plate with a small hole is fixed on the opening for water filling after the water level difference is almost filled, and then water is slowly filled into the pump body again through the small hole in the last sealing plate to test the pressure of the pump body. This kind of pressure testing mode operating procedure is many, and work efficiency is low to the pump of different models, need supporting different closing plates to test, with high costs, the closing plate is bolted connection with being connected of the pump body in addition, reveals easily, has the safety risk on the one hand, and on the other hand causes experimental unsuccessful easily.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a in single-stage pump hydrostatic test's project organization.
The utility model discloses a realize like this, provide a project organization for single-stage pump hydrostatic test, including the first apron that is used for sealed pump body import flange position and the third apron that is used for the second apron of the big terminal surface of sealed pump body screw thread and is used for sealed pump body export flange, be equipped with connecting rod lower extreme and second apron fixed connection, upper end and first apron swing joint, and the upper surface edge of second apron is the step structure of multistage outside-in gradual increase, connecting rod upper end threaded connection locking cap is equipped with the water injection hole on the third apron.
And furthermore, a sealing ring groove is arranged on the contact surface of the first cover plate and the pump body inlet flange, a sealing ring groove is arranged on each layer of step of the step structure of the second cover plate, a sealing ring groove is arranged on the lower surface of the locking cap, and sealing rings are arranged in the sealing ring grooves of the first cover plate, the second cover plate and the locking cap.
Further, the third cover plate is connected with the pump body outlet flange through bolts.
Compared with the prior art, the utility model has the advantages of:
1. the sealing between the pump body inlet flange and the sealing plate at the large end face of the thread and the pump body is realized in a pressing mode, and the sealing ring is arranged on the contact surface of the cover plate and the pump body, so that the problem of easy leakage caused by the fact that a plurality of bolts are needed to realize sealing in the prior art is solved;
2. through the stair structure on the second apron to the pump body that makes different models can all carry out hydrostatic test with this project organization, saves the cost, and work efficiency is high.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and embodiments:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the utility model provides a project organization for single-stage pump hydrostatic test, including the first apron 1 that is used for sealed pump body import flange position and the second apron 2 that is used for the big terminal surface of sealed pump body screw thread and the third apron 3 that is used for sealed pump body export flange, be equipped with connecting rod 4 lower extreme and 2 fixed connection of second apron, upper end and 1 swing joint of first apron, and the upper surface edge of second apron 2 is the step structure of multistage outside-in gradual increase, connecting rod 4 upper end threaded connection locking cap 5 is equipped with the water injection hole on the third apron 3.
When using this project organization to carry out hydrostatic test to the pump body, at first take off first apron 1 from connecting rod 4, place the big terminal surface opening of screw thread of the pump body on second apron 2 on the step that this model pump body corresponds with the hoist and mount instrument, again pass connecting rod 4 with first apron 1 and cover on the import flange of the pump body, rotate locking cap 5, locking cap 5 downstream is until compressing tightly first apron 1 on the import flange, also compress tightly second apron 2 at the big terminal surface opening of screw thread simultaneously, can irritate water in the pump body through the export flange of the pump body this moment, almost fill up the back, pass through threaded connection in export flange department with third apron 3, water injection once more in to the pump body through the water injection hole on third apron 3, can carry out the hydrostatic test of the pump body.
In order to further enhance the sealing effect between the cover plate and the pump body, as an improvement of the technical scheme, a sealing ring groove is arranged on the contact surface of the first cover plate 1 and the inlet flange of the pump body, a sealing ring groove is arranged on each layer of step of the step structure of the second cover plate 2, a sealing ring groove is arranged on the lower surface of the locking cap 5, and a sealing ring 6 is arranged in the sealing ring grooves of the first cover plate 1, the second cover plate 2 and the locking cap 5.
The sealing ring 6 is a flexible sealing ring, the height of the sealing ring is slightly higher than that of each sealing ring groove (for example, 1-3mm), and after each cover plate is compressed in a compression or bolt connection mode, the sealing ring is extruded simultaneously to realize sealing.
As a specific connection mode of the third cover plate 3, the third cover plate 3 is connected with the pump body outlet flange by bolts.
