Abstract
A tubular pump with an adjustable inflow angle of a back guide vane belongs to the technical field of water pumps. The tubular pump comprises an inlet taper pipe, a blade-adjustable impeller, a back guide vane, a rear guide vane body and a pump shaft, wherein the blade-adjustable impeller is mounted on the pump shaft. The tubular pump is characterized in that the back guide vane is provided with an adjustable head part and a fixed rear part fixedly connected with the rear guide vane body; the adjustable head part is provided with a pivot and is mounted in the rear guide vane body through the pivot; one end of the pivot extends outside the rear guide vane; and a rotary adjusting device is arranged at the pivot end. According to the utility model, the rotary adjusting device drives the pivot to rotate so as to allow the adjustable head part of the rear guide vane to rotate around the axis of the pivot, and accordingly the inflow angle of the back guide vane can be adjusted; and particularly, due to the cooperation of the water pump blade adjustment and inflow angle adjustment of the rear guide vane, the liquid flow angle of the water stream at the outlet of the impeller is ensured to be consistent with the inflow angle of the rear guide vane, thereby meeting the design requirements of the impeller and the guide vane. The tubular pump has the advantages of wide flow regulating range, wide lift adaptation range and large high-efficiency area range.
Description
Technical field
The utility model relates to the structure of the structural type of through-flow pump, particularly rear guide vane, belongs to the pump technology field.
Background technique
Through-flow pump is widely used in big flow, low lift pumping plant, adopt blade can regulate impeller mostly, can be according to the variation of flow and lift, regulate the water pump blade laying angle, change pump performance, satisfy the operation needs of lift variation significantly, but still have the narrow shortcoming in efficient district, can not give full play to economic benefit and the social benefit of pump station engineering.For the through-flow pump that adopts the frequency control of motor speed operation, not only can increase the equipment of pumping station investment, the energy consumption of frequency conversion equipment can reduce pumping plant efficient, and after the lift reduction may take place, flow did not satisfy situation about requiring.
The model utility content
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, a kind of compact structure, easy to adjust, the stable adjustable through-flow pump of rear guide vane inflow angle are provided, by regulating the rear guide vane inflow angle, make through-flow pump in very large range satisfy flow and lift variation requirement, enlarge efficient district scope effectively.
The purpose of this utility model is to realize like this, the adjustable through-flow pump of a kind of rear guide vane inflow angle, comprise that import Taper Pipe, blade can regulate impeller, rear guide vane, rear guide vane body, pump shaft, blade can be regulated impeller and be installed on the pump shaft, it is characterized in that, described rear guide vane is provided with adjustable nose section and fixing afterbody, fixedly afterbody and rear guide vane body are connected and fixed, adjustable nose section is provided with pivot, adjustable nose section is by being pivotally mounted in the rear guide vane body, it is external that one end of pivot extends to rear guide vane, and pivot pin end is provided with rotary regulator.
Described rotary regulator is connected to form by servomotor, control ring, connecting lever and linkage mechanism, and connecting lever is connected with described pivot pin end with linkage mechanism.
The utlity model has compactness rational in infrastructure, easy to adjust, can be according to flow and lift requirement, control ring by rotary regulator rotates under the promotion of servomotor, the adjustable nose section that forces connecting lever and connecting rod to drive rear guide vane rotates around pivot, thereby reach the import laying angle (inflow angle) that changes rear guide vane, change the purpose of through-flow pump performance, enlarge flow and the lift operating range of pump effectively, particularly can regulate the impeller joint with the blade of water pump regulates, the flow angle that guarantees the impeller outlet current is consistent with the rear guide vane inflow angle, satisfy the designing requirement of impeller and stator, the operating mode that can satisfy lift to alter a great deal and require flow to remain unchanged substantially, and make water pump in the operation of efficient district as far as possible, improve operational efficiency.
