The utility model discloses simple structure, reasonable in design through setting up the decompression chamber, reduces the pressure of liquid and makes it discharge pump external, makes the pump body can not produce the leakage, improves the sealing performance of the pump body.
Description
Technical Field
The utility model relates to the technical field of pumps, especially, relate to delivery pump decompression chamber structure.
Background
The slurry delivery pump in the prior art forms a seal cavity between the upper end face of the last-stage seal cavity and the motor support frame adjacent to the upper side, a pressure relief device is not arranged on one side of the seal cavity, after liquid flows into the seal impeller from a working impeller, the pressure is continuously increased under the action of the centrifugal force of the rotation of the seal impeller, the center of the seal impeller is a low-pressure area, the outer ring is a high-pressure area, and under the condition that the pressure is continuously increased, the liquid easily runs upwards to cause the leakage of the pump body.
Disclosure of Invention
The utility model discloses the purpose is to solve above-mentioned technical problem, provides delivery pump decompression chamber structure.
In order to realize the technical purpose, reach foretell technical requirement, the utility model discloses the technical scheme who adopts is: delivery pump decompression chamber structure, including the motor support frame, its characterized in that: motor support frame central point puts and is provided with the shaft coupling support frame, shaft coupling support frame one side upper end is provided with the overflow pipe, overflow pipe one end extends to motor support frame's lateral wall, motor support frame's bottom is provided with the cavity of indent, motor support frame bottom one side is provided with first baffle A, first baffle B, second baffle, first baffle A, first baffle B, second baffle constitute the decompression chamber with motor support frame lateral wall, be provided with the square hole on the motor support frame axial lateral wall in the decompression chamber, be provided with the release hole on the second baffle, cavity, square hole, decompression chamber, release hole form the liquid flow way, be provided with the washing water hole on the cavity inner wall.
Preferably: the lowest overflow point of the pressure relief hole is flush with the lowest point of the square hole or is 1-2cm lower than the lowest point of the square hole.
Preferably: the axial section of the outer circumference of the motor support frame is trapezoidal, and the axial section of the decompression chamber is inverted trapezoidal.
Compared with the traditional structure, the beneficial effects of the utility model are that: simple structure, reasonable in design through setting up the decompression chamber, utilizes the volume change to produce pressure variation, and liquid gets into decompression chamber back pressure and descends in the twinkling of an eye, then discharges the pump body through the pressure relief vent outside for liquid can not up run again, causes the pump body to leak, has further strengthened the sealing performance of the pump body through setting up of overflow pipe.

Detailed Description
The present invention will be further explained below.
With reference to the accompanying drawings, the delivery pump decompression chamber structure comprises a motor support frame 1, and is characterized in that: 1 central point of motor support frame puts and is provided with shaft coupling support frame 11, 11 one side upper ends of shaft coupling support frame are provided with overflow pipe 2, 2 one ends of overflow pipe extend to motor support frame 1's lateral wall, motor support frame 1's bottom is provided with the cavity 13 of indent, 1 bottom one side of motor support frame is provided with first baffle A5, first baffle B6, second baffle 3, first baffle A5, first baffle B6, second baffle 3 and 1 lateral wall of motor support frame constitute decompression chamber 4, be provided with square hole 14 on the 1 axial lateral wall of motor support frame in decompression chamber 4, be provided with release hole 31 on the second baffle 3, cavity 13, square hole 14, decompression chamber 4, release hole 31 form the liquid runner, be provided with on the cavity 13 inner wall and wash water hole 12.
In the preferred embodiment, the lowest overflow point of the pressure relief hole 31 is flush with the lowest point of the square hole 14 or 1-2cm lower than the lowest point of the square hole 14.
In the preferred embodiment, the axial section of the outer circumference of the motor support frame 1 is trapezoidal, and the axial section of the decompression chamber 4 is inverted trapezoidal.
During the concrete implementation, liquid throws away through sealed impeller to the cavity 13, flows into decompression chamber 4 through square hole 14, and pressure descends in the twinkling of an eye after liquid gets into decompression chamber 4, and rethread release hole 31 flows outside the pump body, through the setting of decompression chamber for liquid can not up run again, causes the pump body to leak, has further strengthened the sealing performance of the pump body through the setting of overflow pipe 2.
The above embodiments of the present invention are only examples for clearly illustrating the present invention, but not for limiting the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
