Abstract
The utility model relates to a wall-hanging stove pump which comprises an impeller and a water absorbing chamber. The impeller and the water absorbing chamber are arranged in a pump body. The wall-hanging stove pump is characterized in that a rectification frame is further arranged in the pump body and arranged in the water absorbing chamber, and the water inlet end of the rectification frame faces the impeller. The wall-hanging stove pump has the advantages that the rectification frame is arranged between the water absorbing chamber and the impeller to adjust the flow state of fluid at an inlet of the impeller and reduce secondary backflow, the flow turbulence degree in the impeller is reduced, hydraulic losses in a volute are reduced, and therefore the efficiency of the pump is improved; a water distributing plate is arranged so that the fluid flowing out of the impeller evenly flows to the rectification frame, the formation of secondary flow is further reduced, energy losses are avoided, and the efficiency of the pump is improved; the special-shaped rectification frame is adopted so that the resistance of the fluid can be reduced and the efficiency of the pump can be improved.
Description
Wall-hung boiler pump.
Technical field
The utility model relates to a kind of water pump, relates in particular to a kind of wall-hung boiler pump.
Background technique
The exhaust of wall-hung boiler dedicated pump is the bubble producing in heating system and water system pipeline for discharging, and is an important indicator evaluating wall-hung boiler dedicated pump operational reliability.For ensureing the exhaust effect of pump, the fluidised form of often upsetting by pump structure the liquid that enters suction chamber makes water, gas produce density difference, finally makes bubble floating, fluid sink, and air displacement is ensured.The shortcoming that the pump of this structure exists: the fluid entering in impeller presents non-symmetric State, and at the inner Secondary Flow that forms of impeller, reduced to a certain extent pump efficiency.And erratic fluid enters after spiral case and produces larger impact loss and secondary back, causes pump efficiency to reduce greatly, than same performance hot water circulating pump efficiency low 7% ~ 10%.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above of prior art existence and a kind of wall-hung boiler pump is provided, by rectifying frame being set between suction chamber and impeller, regulate the fluidised form of impeller inlet fluid, reduce secondary back, in reducing the disorderly degree of Flow in Impeller, reduce hydraulic loss in spiral case, and then raising pump efficiency, overcome traditional wall-hung boiler pump and reduced the deficiency of pump efficiency owing to focusing on exhaust.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: wall-hung boiler pump, comprise the pump housing, be arranged on impeller and suction chamber in the pump housing, it is characterized in that being also provided with in the described pump housing rectifying frame, described rectifying frame is arranged in suction chamber, and the feed-water end of described rectifying frame is towards impeller.By rectifying frame is set, regulate the fluidised form of impeller inlet fluid, reduce secondary back, in reducing the disorderly degree of Flow in Impeller, reduce hydraulic loss in spiral case, and then improve pump efficiency.
As further improving and supplementing technique scheme, the utility model adopts following technical measures: in the described pump housing, be also provided with a point water plate, described rectifying frame is erected on point water plate, and the water intake of described rectifying frame and the corresponding setting of water outlet that divides water plate.Divide the setting of water plate to make the rectifying frame that flows to from impeller fluid equilibrium out, further reduce the formation of Secondary Flow, avoid energy loss, improve pump efficiency.
For flowing of making that fluid can be axisymmetricly, farthest produce water again, air tightness is poor simultaneously, described rectifying frame is X-shaped, and four ends on described X-shaped rectifying frame arrange respectively sets up pin, sets up standing on point water plate that pin all fixes described in every.
In order to reduce the resistance of convection cell, improve pump efficiency, the cross section of four rectifier arms on described X-shaped rectifying frame is V-shaped, and its tip is import department.
In order farthest to reduce the resistance of convection cell, the arc surface that two rectification faces of described V-arrangement rectifier arm are evagination.
Described in every, set up pin all vertical with four described rectifier arm place planes.Such scheme, equally for farthest reducing the object of the resistance of convection cell.
Set up pin described in installing every and be fixedly connected with a point water plate by welding manner for convenient, or, described rectifying frame with divide the water plate structure that is formed in one.
The beneficial effect the utlity model has: 1, by rectifying frame being set between suction chamber and impeller, regulate the fluidised form of impeller inlet fluid, reduce secondary back, in reducing the disorderly degree of Flow in Impeller, reduce hydraulic loss in spiral case, and then improve pump efficiency.2, divide the setting of water plate to make the rectifying frame that flows to from impeller fluid equilibrium out, further reduce the formation of Secondary Flow, avoid energy loss, improve pump efficiency.3, in order to reduce the resistance of convection cell, improve pump efficiency, adopt the rectifying frame of given shape.
