Description
Technical field
The utility model relates to a kind of pump technical field that belongs to, and relates in particular to a Under Water Pumps.
Background technique
Under Water Pumps is made specification according to the difference (being generally 1 to 1.5m) that stretches into container length.The Under Water Pumps working portion is submerged in the liquid, therefore axle envelope no liquid splash phenomena; The radial force that axially reaches that the pump running produces is supported by rolling bearing and sliding bearing respectively; Stuffing box packing place has cooling system, can take away heat with cooling water according to the temperature of user's working medium.Under Water Pumps is widely used in fields such as industry, agricultural, mine, municipal sewage treatment, especially at production fields such as chemical industry, medicine, suitable conveying has the sewage of particle, in the whole production link critical role is arranged.
Under Water Pumps is a vertical structure, and the pump housing, impeller are immersed in the liquid during work, thereby is easy to starting, does not have the problem of finding time, has characteristics such as not having leakage simultaneously, and the degree of depth can reach 0.5～7 meter under the liquid.Its principle is: a kind of pump that utilizes the interaction of rotary vane and liquid to transmit energy, utilizes action of centrifugal force to increase fluid pressure and make it to flow.Usually Under Water Pumps is made up of pump case, connecting tube, impeller, rotating shaft etc.Power engine drives rotating shaft, and liquid is forced to produce centrifugal force with wheel rotation in the rotating shaft impeller high speed rotating in pump case, pump.Centrifugal force forces liquid to be dished out from impeller periphery, converges into the high speed and high pressure liquid pump case excavationg pump of flowing through and enters outlet pipe outward, and the impeller center forms low pressure, thereby sucks new liquid stream, constitutes continuous liquid stream conveying effect.The turning shaft structure of prior art as shown in Figure 1, the design rotating shaft is one whole because the length of rotating shaft is longer, precision is difficult to guarantee that it is bigger to beat during gold machining, simultaneously when the rotating shaft wearing and tearing, just needs whole replacing.The connecting tube structure of prior art as shown in Figure 2, the inside of connecting tube all is straight-through tube, connect to support between in axle and the connecting tube, when particularly the degree of depth is dark under the liquid, beating of the intermediate portion of rotating shaft is very serious, and then drives beating of whole rotor part, influences the stability of product performance.
The model utility content
The utility model is the shortcoming at above-mentioned existence, provides stability good, a kind of Under Water Pumps that machining accuracy is high.
The technological scheme that technical problem adopted that the utility model solves is:
A kind of Under Water Pumps comprises pump case, connecting tube, impeller, rotating shaft, and connecting tube divides goes up connecting tube and second line of a couplet adapter, it is characterized in that described rotating shaft divides upward rotating shaft and lower rotary shaft, connects with coupling between last rotating shaft and lower rotary shaft.The design rotating shaft of prior art is one whole, because precision is difficult to guarantee that it is bigger to beat during the longer gold machining of the length of rotating shaft.And the utility model has shortened by the length of comparing every axle after improving with original technology, just can guarantee the precision of axle during gold machining, reduced to beat, the efficient of water pump and stabilised efficiency have obtained big raising, simultaneously little because of beating, the wearing and tearing of rotor part just reduce, and when changing axle can according to the degree of wear only change wherein a part and need be as originally will whole replacing, thereby maintenance cost has also obtained reduction.
During concrete the use, be provided with bearing support in last connecting tube and second line of a couplet adapter, bearing support is provided with bearing, and last rotating shaft and lower rotary shaft pass the bearing of connecting tube and second line of a couplet adapter inner pedestal respectively, and bearing and last rotating shaft and lower rotary shaft are suitable.The inside of the connecting tube of prior art all is straight-through tube, be not connected and fixed between in axle and the connecting tube, when particularly the degree of depth was dark under the liquid, beating of the intermediate portion of rotating shaft was very serious, and then drive beating of whole rotor part, influence the stability of product performance.The utility model is by improving design, original connecting tube inner straight pipe is changed into the connecting tube of inner tape spool bearing, guarantee that every rotating shaft mixes two bearings and fixed, like this rotating shaft beat just littler, the efficient of pump and stability have just obtained further raising, and the wearing and tearing of rotor part just still less, maintenance cost is also just lower.
The beneficial effects of the utility model are: the utility model leads to the into improvement of countershaft, connecting tube, and its efficient is improved, good stability, and prolonged the working life of rotor part, the utilization efficiency that improves equipment, reduction maintenance cost.
