The underwater stable operation of Under Water Pumps needs premised on the excellent support of bearing, therefore needs to carry out effective sealing to bearing, divides medium to enter bearing cause damage to it with preventing portion.But existing Under Water Pumps is due to the design deficiency of the aspect such as sealing configuration and material, there is sealing effect bad more, easily causes the problems such as leakage, so that greatly shorten the working life of Under Water Pumps bearing.
Therefore, prior art has yet to be improved and developed.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of underwater pump, is intended to solve existing Under Water Pumps sealing poor, the problem that working life is short.
The technical solution of the utility model is as follows:
A kind of underwater pump, comprise the pump housing and pump cover, pump cover is fixed on the pump housing, the two forms airtight chamber, impeller is provided with in airtight chamber, described impeller is fixed in rotating shaft, the end of described rotating shaft is connected with motor-driven by coupling, in the outside of rotating shaft, cover has support tube, the upper end portion of support tube is provided with mounting disc, mounting disc is fixed with upper bracket, upper bracket is fixed with bearing box, bearing is provided with in bearing box, described bearing housing is in rotating shaft, in the inside of bearing box and the lower space being positioned at bearing is filled with stuffing box packing, the described pump housing is provided with liquid-inlet and liquid outlet, liquid outlet connects drain pipe, the end of drain pipe is provided with outlet(discharge) flange, described drain pipe is also fixed in mounting disc.
Preferably, the bottom of described bearing box is provided with sealing rubber ring, and described sealing rubber ring is enclosed within rotating shaft.
Preferably, rotating shaft is disposed with the first stuffing box gland and the second stuffing box gland, the first stuffing box gland and the second stuffing box gland are all in truncated cone shape.
Preferably, described first stuffing box gland and the second stuffing box gland are fastened on support tube respectively by square fixed block.
Preferably, in described rotating shaft, also cover has two panels paper washer, at a distance of 5-10cm between this two panels paper washer.
Beneficial effect:
Bearing is placed in bearing box by the utility model, and in the lower state stuffing box packing of bearing box, thus bearing is sealed preferably, extend its working life; In addition, also rubber ring is set by the bottom at bearing box, rotating shaft arranges two stuffing box glands and two panels paper washer, make to be able to further enhancing to the sealing effect of bearing, and then add the working life of Under Water Pumps.Find compared with Under Water Pumps similar with other, similar chemical industry Under Water Pumps adopts be approximately 3600 hours the working life of mechanical seal, the utility model Under Water Pumps is through improving, sealing can reach 7000 hours working life, greatly increase working life, reduce maintenance, safeguard the trouble brought.In addition, above-mentioned improvement of the present utility model all can not impact the overall volume of Under Water Pumps and pumping efficiency etc.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
The utility model provides a kind of underwater pump, for making the purpose of this utility model, technological scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model Under Water Pumps, producer called after GCLD type pump, it is one step single sucking liquid following formula centrifugal pump, and main parts size is made up of component such as the pump housing, pump cover, rotating shaft, impeller, support tube, mounting disc, coupling, bearings.The utility model GCLD type pump is by a series of improvement of the aspects such as sealing configuration, and sealing can reach 7000 hours working life, greatly increases working life, reduces maintenance, safeguards the trouble brought.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of underwater pump, comprise the pump housing 1 and pump cover 2, pump cover 2 is fixed on the pump housing 1, and the two forms airtight chamber.In airtight chamber, be provided with impeller 3, described impeller 3 is fixed in rotating shaft 4, and the end of described rotating shaft 4 is connected with motor-driven by coupling 5.In the outside of rotating shaft 4, cover has support tube 6, and the upper end portion of support tube 6 is provided with mounting disc 7, mounting disc 7 is fixed with upper bracket 8, upper bracket 8 is fixed with bearing box 9, be provided with bearing 10 in bearing box 9, described bearing 10 is enclosed within rotating shaft 4.In the inside of bearing box 9 and the lower space being positioned at bearing is filled with stuffing box packing 11.The described pump housing is provided with liquid-inlet and liquid outlet, liquid outlet connects drain pipe 12, and the end of drain pipe 12 is provided with outlet(discharge) flange 13, and described drain pipe 12 is also fixed in mounting disc 7.
As to further improvement of the utility model, the bottom of described bearing box 9 is provided with sealing rubber ring 14, and described sealing rubber ring 14 is enclosed within rotating shaft 4.
Further, rotating shaft is disposed with the first stuffing box gland 15 and the second stuffing box gland 16, first stuffing box gland 15 and the second stuffing box gland 16 all in truncated cone shape.The two is fastened on support tube 6 respectively by square fixed block 17.
Further, in described rotating shaft 4, also cover has two panels paper washer 18, and this two panels paper washer be arranged in parallel, at a distance of 5-10cm, forms air containment chamber therebetween.
Working procedure of the present utility model is roughly as follows:
Generally driven by motor, before startup pump, in the pump housing and suction line, be full of liquid.When impeller High Rotation Speed, impeller drives interlobate liquid to rotate together, and due to the effect of centrifugal force, liquid is thrown toward impeller outer edge from impeller central, and kinetic energy also increases thereupon.After liquid enters pump case, because the runner in volute shaped pump casing expands gradually, flow rate of liquid reduces gradually, and a part of kinetic energy is static energy, so liquid flows out along exhaust port with higher pressure.Meanwhile, impeller central place forms certain vacuum because liquid is thrown out of, and the pressure at liquid level place is higher than impeller central place, and therefore, the liquid of suction line enters in pump under differential pressure action.Impeller does not stop to rotate, and liquid is also continuously inhaled into and extrudes.
The part do not addressed in aforesaid way is taked or uses for reference prior art to realize.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection domain that all should belong to the utility model claims.
