Abstract
The utility model discloses a balancing water return pipe component which comprises balancing water pipes. The balancing water return pipe component is characterized in that shoot-through sight glass is arranged in each balancing water pipe, a pipe back cap is arranged at one end of each balancing water pipe, and the other end of each balancing water pipe is connected with a balancing water receiving pipe through an elbow. According to the optimized embodiments of the balancing water return pipe component, the balancing water pipes comprise the first balancing water pipe and the second balancing water pipe, internal threads are arranged at the two ends of the shoot-through sight glass, the first balancing water pipe is in threaded connection with one end of the shoot-through sight glass, and the second balancing water pipe is in threaded connection with the other end of the shoot-through sight glass. The advantage of the balancing water return pipe component lies in the using method, and whether a balancing mechanism works normal or not can be found or judged in time by directly observing the water return situations in a water return pipe in a pump operation process.
Description
Technical field
The utility model relates to the innovation to multistage pump, is specifically related to a kind of balanced water returning pipe parts.
Background technique
In multistage pump, balanced water returning pipe parts connect cavity and the pump intake after balanced controls, are used for the equilibrirm water after balanced controls pressure release to guide to import or the inlet ductwork of pump, and the high voltage terminal of pump is connected with low voltage terminal.Pressure relief water after balanced controls, by being back to the import of pump with the pressure difference of import or inlet ductwork, pump is under stable operating conditions like this, and balanced controls are normally worked, and its axial force is balanced, and has ensured the safe and reliable operation of pump.There is following shortcoming in existing balanced water returning pipe modular construction.
1, cannot observe directly the whether unobstructed of backwater in balanced water returning pipe.
If 2, balanced water returning pipe is stopped up by foreign material, Balance disc cannot normally be worked, and wear and tear.
If 3, pump occurs greatly extremely in running, dismounting balanced water returning pipe checks whether Balance disc weares and teares, and wastes time and energy.
Model utility content
The purpose of this utility model is to provide a kind of balanced water returning pipe parts, in the running of pump, can, directly by observing the backwater situation in return pipe, find in time or judge whether balanced controls normally work.
To achieve these goals, the technical solution of the utility model is as follows: a kind of balanced water returning pipe parts, comprise balancing pipeline, it is characterized in that being provided with a straight-through sight glass in described balancing pipeline, one end of balancing pipeline is provided with pipe back of the body cap, and the other end of balancing pipeline connects equilibrirm water by bend pipe and takes over.According to preferred embodiment of the present utility model, described balancing pipeline comprises the first balancing pipeline and the second balancing pipeline, described straight-through sight glass two ends are provided with internal thread, the threaded one end of described the first balancing pipeline and described straight-through sight glass is connected, and the other end of described the second balancing pipeline and described straight-through sight glass is threaded.
Balanced water returning pipe parts of the present utility model are a kind of balanced water returning pipe parts of spying on, can in pump operation process, observe directly the backwater in water pipe, thereby find in time pump in running because backwater is smooth or Balance disc friction, cause pump irregular operation, provide convenience to the fault diagnosis of multistage pump.The utility model has the advantage of using method, in the running of pump, can, directly by observing the backwater situation in return pipe, find in time or judge whether balanced controls normally work.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use installation diagram of the present utility model.
Embodiment
On existing balanced water returning pipe parts basis, divide two-part processing by balancing pipeline, with the connection of internal thread straight-through sight glass.As shown in Figure 1, balancing pipeline is processed into the first balancing pipeline 2 and the second balancing pipeline 4, links together by internal thread straight-through sight glass 3.These balanced water returning pipe parts are as shown in Figure 1: 1, pipe back of the body cap; 2, the first balancing pipeline; 3, internal thread straight-through sight glass; 4, the second balancing pipeline; 5, elbow; 6, equilibrirm water is taken over.
This structure adopts the balanced water returning pipe parts of spying on of the present utility model to replace former parts (see figure 2), can in pump operation process, observe directly the backwater in water pipe, thereby find in time pump in running because backwater is smooth or Balance disc friction, cause pump irregular operation.Fault diagnosis to multistage pump provides convenience.
In view of multistage pump self structure feature, the method also can be to meeting the machine envelope cleaning hose of structural requirement, and water-cooling tube improves.In existing structure, owing to dividing pipeline and freely usually do not cause pump irregular operation in pump structure top, the pipeline component of spying on so this, make simple, cost is low, under the prerequisite that meets structural requirement, it is transformed, and has improved greatly the reliability of pump in actual motion, and can find in time solution to the undesirable element in running, thereby improve the service life of pump.
