Description
Technical field
The utility model relates to mechanical engineering pump technical field, specifically a kind of equilibrirm water cavity configuration of water pump.
Background technique
As everyone knows, traditional sealing water cavity and machine sealing chamber are two independent structures, and function singleness, with associating on axial thrust balancing devices nonfunctional, therefore can only increase the length of pump in multistage pump, cause complex structure, cost increases.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides a kind of novel structure, safe and reliable, long service life, conserve space, the water pump equilibrirm water cavity configuration reduced costs.
The utility model solves the technological scheme that its technical problem adopts:
A kind of water pump equilibrirm water cavity configuration, be provided with the pump housing, sealing radiator and pump shaft, described sealing radiator is fixedly connected with the pump housing, described pump shaft is through in the pump housing and sealing radiator, pump shaft in sealing radiator is provided with Balance disc and machine envelope, it is characterized in that being provided with balanced water returning pipe and wear ring, described sealing radiator outer end is provided with wear ring, sidewall is provided with backwater through hole, described balanced water returning pipe one end is connected with backwater through hole, the other end is connected with pump housing suction port, axial clearance is formed between described wear ring and Balance disc end face, by axial clearance, the pressure chamber of two-part up and down in sealing radiator separated and form pressure reduction, be beneficial to the axial force helping Balance disc autobalance water pump, simultaneously, the medium leaked out after Balance disc by impeller outlet is through the gap between Balance disc and sealing radiator, axial clearance, water cavity in sealing radiator and balanced water returning pipe are back to pump housing suction port, not only play the pressure balanced effect of sealing radiator, but also pass through the medium washes leaked mechanical seal, reach and saved space, reduce cost.
The utility model can show end face tank by Circle-Array on the Balance disc end face corresponding with described wear ring, and described end face tank radial direction is arranged, and is beneficial to the capacity of reflux strengthening medium, reaches pressure balanced effect further.
The transverse section semicircular in shape tank of end face tank described in the utility model, the radius of described end face tank is preferably 1mm.
The utility model, owing to adopting said structure, has novel structure, safe and reliable, long service life, conserve space, the advantage such as to reduce costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character: sealing radiator 1, pump shaft 2, Balance disc 3, machine envelope 4, balanced water returning pipe 5, wear ring 6.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in Figure 1, a kind of water pump equilibrirm water cavity configuration, be provided with the pump housing, sealing radiator 1 and pump shaft 2, described sealing radiator is fixedly connected with the pump housing, described pump shaft 2 is through in the pump housing and sealing radiator 1, pump shaft 2 in sealing radiator 1 is provided with Balance disc 3 and machine envelope 4, it is characterized in that being provided with balanced water returning pipe 5 and wear ring 6, described sealing radiator 1 outer end is provided with wear ring 6, sidewall is provided with backwater through hole, described balanced water returning pipe 5 one end is connected with backwater through hole, the other end is connected with pump housing suction port, axial clearance is formed between described wear ring 6 and Balance disc 3 end face, by axial clearance, the pressure chamber of two-part up and down in sealing radiator 1 separated and form pressure reduction, be beneficial to the axial force helping Balance disc 3 autobalance water pump, simultaneously, the medium leaked out after Balance disc 3 by impeller outlet is through the gap between Balance disc 3 and sealing radiator 1, axial clearance, water cavity in sealing radiator and balanced water returning pipe 5 are back to pump housing suction port, not only play the pressure balanced effect of sealing radiator, but also pass through the medium washes leaked mechanical seal, reach and saved space, reduce cost.
The utility model can show end face tank by Circle-Array on Balance disc 3 end face corresponding with described wear ring 6, described end face tank radial direction is arranged, be beneficial to the capacity of reflux strengthening medium, reach pressure balanced effect further, the transverse section semicircular in shape tank of end face tank described in the utility model, the radius of described end face tank is preferably 1mm.
As shown in Figure 1, in pump operation process, pump housing suction port is back to from the water cavity in the gap of medium through between Balance disc 3 and sealing radiator 1 that impeller outlet leaks out after Balance disc 3, axial clearance, end face tank, sealing radiator and balanced water returning pipe, not only play the axial force helping Balance disc autobalance water pump, and, also serve the effect of relief developing machine envelope in the process.
The utility model, owing to adopting said structure, has novel structure, safe and reliable, long service life, conserve space, the advantage such as to reduce costs.
