The import cavity radially still seted up the more than one access hole, more than one access hole department all is equipped with the apron. Through setting up the access hole in the import on the cavity, realized point -to -point convenient change to the part that has damaged, improved the speed of dismantling with the assembly greatly, reduced maintenance time, reduce the maintenance cost more than 30%. Through the structure of adjustment universal joint, realize the rapid Assembly and the dismantlement of single -screw (single screw) pump, reduce working strength, improve more than the work efficiency 30%.
Description
Technical field
The utility model belongs to screw pump technology field, is specifically related to a kind of helical rotor pump.
Background technique
At present, in the conventional construction of existing helical rotor pump, rotor, transmission shaft carry out being connected and transmission with universal joint by fixing pivot pin, universal joint is arranged in closed import cavity, import cavity is fixed by bolt and bearing support, stator, outlet connection again, and Sealing (mechanical seal or packing seal) is arranged on transmission shaft simultaneously.And rotor, Sealing (mechanical seal or packing seal) are helical rotor pump easily worn parts, need often to change.There is following problem in tradition helical rotor pump structure: 1. dismounting inconvenience: when disassembling rotor, transmission shaft, after needing first to remove outlet connection, stator and closed import cavity, rotor, transmission shaft could be separated with universal joint after removing fixing pivot pin again, thus just can carry out follow-up dismounting.And need when installing to assemble according to the reverse-order of dismounting, efficiency is lower; 2. change easily damaged parts inconvenient: more during exchanging rotor, need to be undertaken can changing after rotor is disassembled by the requirement described in 1 clause; When changing Sealing, need to be undertaken can carrying out replacing Sealing after transmission shaft is disassembled by the requirement described in 1 clause.
Above-mentioned problem is unfavorable for dismounting and the maintenance of helical rotor pump, the helical rotor pump that particularly some specifications are larger, and it is outstanding that these problems just seem especially.The probability that operating mode in addition residing for helical rotor pump determines the damage of helical rotor pump easily worn part is very high, virtually turn increases the frequency that helical rotor pump is safeguarded, brings many inconvenience to the user of helical rotor pump.
Summary of the invention
In order to solve the problem of easily damaged parts dismounting that existing helical rotor pump exists, maintenance and replacing inconvenience, the utility model provides a kind of convenient reassembling type helical rotor pump.
A kind of convenient reassembling type helical rotor pump comprises the transmission shaft 1, universal joint 6, rotor 9, stator 10 and the outlet connection 11 that connect successively, and wherein the inner of the inner of transmission shaft 1, universal joint 6 and rotor 9 is positioned at the import cavity 5 of tubulose; The side radial direction of described import cavity 5 offers import;
Described universal joint 6 is Hooke's joint.
The radial direction of described import cavity 5 also offers more than one access hole, and more than one access hole place is equipped with cover plate.
The import cavity 5 of described import both sides offers access hole respectively.
The diameter of described access hole is less than the diameter of described import.
Advantageous Effects of the present utility model embodies in the following areas:
1. the utility model by arranging access hole on import cavity, achieves the point-to-point convenient changing to part of damage, substantially increase the speed of dismounting and assembling, reduce maintenance time, reduce maintenance cost more than 30%.
2., by the structure of adjustment universal joint, change universal joint and rotor, the connection of transmission shaft and the kind of drive, realize quick assembling and the dismounting of helical rotor pump, reduction working strength, increases work efficiency more than 30%.

Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Embodiment
See Fig. 1, a kind of convenient reassembling type helical rotor pump comprises the transmission shaft 1, universal joint 6, rotor 9, stator 10 and the outlet connection 11 that connect successively, and wherein the inner of the inner of transmission shaft 1, universal joint 6 and rotor 9 is positioned at the import cavity 5 of tubulose; The side radial direction of import cavity 5 offers import.
Improvement is: universal joint 6 is Hooke's joint; Transmission is carried out by modes such as flat key, four square holes or hexagon rings.
The radial direction of import cavity 5 also offers two access holes, and two access holes lay respectively at the both sides of import, and two access hole places are all provided with cover plate 7 by pin for suppressing metal 8.The diameter of access hole is less than the diameter of described import.
See Fig. 2, the utility model can be changed greatly little, break the whole up into parts, can respectively to rotor part (left end portion), import cavity portion (intermediate portion) and bearing support part (right end portion) are assembled respectively, and then by each several part by pin for suppressing metal 4, pin for suppressing metal 8 carry out fastening be connected, namely easy-to-operat again reduces Product Assembly difficulty.Unloading process carries out in the other direction by assembling.
See Fig. 5, in traditional architectures, if changed rotor, need the parts such as import cavity 5, universal joint 6, stator 10, outlet connection 11 all to disassemble and just to carry out afterwards, waste time and energy, efficiency is low.See Fig. 3, for the utility model, when rotor 9 be damaged need change time, the cover plate 7 of rotor-side is removed, by the access hole 4 arranged on import cavity 5, pin for suppressing metal is removed, so just the parts such as rotor 9, stator 10, outlet short circuit head 11 can be disassembled from universal joint 6.After carrying out rotor replacing, then press the reverse-order Assembly part of unloading process, the replacing to rotor and maintenance work can be completed.
See Fig. 5, in traditional architectures, if to Sealing 12(containing packing seal and mechanical seal) change, need the parts such as sealing seat 3, import cavity 5, universal joint 6, rotor 9, stator 10, outlet connection 11 all to disassemble and just to carry out afterwards, waste time and energy, efficiency is low.See Fig. 4, for the utility model, when the Sealing 12(in sealing seat 3 is containing packing seal and mechanical seal) be damaged when needing to change, the cover plate 7 of sealed sides is removed, by the access hole 4 be arranged on import cavity 5, pin for suppressing metal is removed, so just the parts such as transmission shaft 1, bearing support 2, sealing seat 3 can be disassembled from universal joint 6.After Sealing 12 in sealing seat 3 is changed, then press the reverse-order Assembly part of unloading process, the replacing to Sealing 12 and maintenance work can be completed.
