Abstract
The utility model relates to a monitoring device of a multi-stage pump. The multi-stage pump comprises a bearing body, a shaft, a suction casing, a stage casing, an impeller, a guide vane, a discharge casing, a balancing ring, a balancing disc and a tail hood. The monitoring device is composed of a non-hole end cover, a measuring rod and screw nuts. The measuring rod is connected with the non-hole end cover through the screw nuts, and the non-hole end cover is connected with the tail hood. A through hole is formed in the center of the non-hole end cover. The measuring rod is provided with scale marks, the front portion of the measuring rod is provided with a bulb, and the tail portion of the measuring rod is of a hexagonal shape or a square shape. The monitoring device of the multi-stage pump has the advantages that structure is simple, labor intensity is reduced, and the pump is monitored under the condition that the pump needs not dismounting.
Description
Technical field
The utility model relates to a kind of supervisory device of multistage pump.
Background technique
At present, the multistage pump structure of existing DF type on the market (referring to " Paddle Pump Designing handbook P116 China Machine Press) be that impeller, Balance disc, the gimbal of pump all is contained in the pump chamber of pump, the defective of this spline structure is, the surface wear attenuate that Balance disc and gimbal often rub and cause both in running, like this impeller, axial left, impeller and stage casing can rub when wear extent increases to a certain degree, damage impeller, cause scrapping of whole pump.Producing such reason is the wear extent of Balance disc and gimbal not to be monitored timely, and existing multistage pump does not have supervisory device, and only having disintegrates to pump could differentiate wear extent, and the amount of labour is large and not easy to operate.
Summary of the invention
The purpose of this utility model is the defective for existing pump, and a kind of supervisory device of multistage pump simple in structure, easy to use is provided.
The technical solution of the utility model is achieved in that a kind of supervisory device of multistage pump, it comprises bearing support, axle, inlet segment, stage casing, impeller, stator, water exit end, gimbal, Balance disc and tail-hood, described supervisory device is comprised of atresia end cap, measuring rod, nut, measuring rod links to each other with the atresia end cap by nut, and the atresia end cap links to each other with tail-hood.Center at the atresia end cap is provided with through hole.Measuring rod is provided with that graduation line, front portion are provided with bulb, afterbody is six squares or square.
The utility model has the advantages that: simple structure, in the situation of not tearing pump open, pump is controlled monitoring, easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of measuring rod 12 among Fig. 1;
Fig. 3 is the structural representation of atresia end cap 10 among Fig. 1.
Embodiment
As shown in Figure 1, 2, 3, a kind of supervisory device of multistage pump, it comprises bearing support 1, axle 13, inlet segment 2, stage casing 3, impeller 4, stator 5, water exit end 6, gimbal 7, Balance disc 8 and tail-hood 9, described supervisory device is comprised of atresia end cap 10, measuring rod 12, nut 11, measuring rod 12 links to each other with atresia end cap 10 by nut 11, and atresia end cap 10 links to each other with tail-hood 9.Be provided with through hole 17 at the center of atresia end cap 10.Measuring rod 12 is provided with that graduation line 15, front portion are provided with bulb 16, afterbody is six squares or square.
Working principle of the present utility model is as follows: the head design of measuring rod 12 becomes bulb 16, and the centre is made as step, and the middle part is designed with screw thread 14 and graduation line 15; The Center of atresia end cap 10 has through hole 17; Measuring rod 12 passes the through hole 17 of atresia end cap 10, connects with nut 11.
After pump operation a period of time Balance disc 8 and gimbal 7 wear and tear, axle 13 is toward left, need to measure and be, stop the moving row of pump, at this moment unscrew nut 11, promote measuring rod 12 left, the head bulb 16 of measuring rod 12 props up axle 13, from the graduation line 15 of measuring rod 12, can read the Balance disc 8 of pump and the wear extent of gimbal 7, measure and finish fastening nut 11.When wear extent reaches the last item graduation line of measuring rod 12, illustrate that Balance disc 8 and gimbal 7 may wear to the limit, must change.Realize so dexterously the monitoring to pump, alleviated labor intensity, prolonged the working life of pump.
