Abstract
The utility model relates to a vortex pump for water supply for a boiler. The utility model mainly solves problems of lower delivery lift, bigger volume and heavier weight. The utility model is characterized in that a motor and a connection support frame are mutually fixed; a motor shaft passes through the connection support frame to be connected with an impeller. One side of the impeller is in an enclosed type and the other side is provided with a circle of flow channel. According to axial direction, blades are embedded on the impeller in an involute type and are slantwise for an angle. A circle of horseshoe-shaped flow channel which is symmetrical with the flow channel of the impeller is arranged on a pump cover; the inside and the outside of the horseshoe-shaped flow channel are respectively provided with a group of tooth-shaped sealing rings which are mutually meshed. An inlet hole and an outlet hole are arranged on the pump cover, and a platform is arranged between the inlet hole and the outlet hole on the pump cover.
Description
The utility model relates to a kind of peripheral pump, particularly a kind of boiler feed water peripheral pump of low-flow high-lift.
In prior art, the blade of conventional boiler feedwater peripheral pump is straight blade profile, the liquid that flows out from impeller in runner with runner in the liquid knockout loss bigger, its single-stage lift is lower, in order to improve lift, have to increase power and impeller outer diameter, make that its volume ratio is bigger, weight is also heavier.
The purpose of this utility model provides the boiler feed water peripheral pump of little, the in light weight and low-flow high-lift of a kind of volume.
The utility model is by motor, impeller, connecting support and pump cover forms, it is characterized in that: motor be connected support and interfix, motor shaft passes the connection support and links to each other with impeller, motor shaft has a mechanical seal with being connected between the support, the one side of impeller is enclosed type, another side has a circle runner, blade is embedded on the impeller by an angle involute of axioversion formula, pump cover is fixed on and connects on the support, the end face that end face of pump cover and impeller have a circle runner matches, runner with impeller on pump cover has a circle horseshoe type runner relatively symmetrically, at runner inside and outside one group of dentation seal ring that coincide is mutually arranged respectively, one inlet hole and an exit orifice are arranged on pump cover, are platform between enterprising oral pore of pump cover and exit orifice.
Because impeller of the present utility model simultaneously is enclosed type, another side has a circle runner, blade is embedded on the impeller by an angle involute of axioversion formula, pump cover is fixed on and connects on the support, runner with impeller on pump cover has a circle runner relatively symmetrically, so the blade that tilts is accelerated the peripheral velocity that enters liquid in the impeller, and the liquid that flows out from impeller in runner with runner in the liquid knockout loss also reduce thereupon, and one group of dentation seal ring that coincide is mutually respectively arranged at runner inside and outside, so its lift is than higher, can adopt low power motor, its volume ratio is less and weight is low weight.
Below in conjunction with accompanying drawing the utility model is elaborated,
Fig. 1 is a cut-away view of the present utility model,
Fig. 2 is the cut-away view of the utility model pump cover,
Fig. 3 is the plan view of the utility model pump cover,
Fig. 4 is the worm's eye view of the utility model pump cover,
Fig. 5 is that figure cuts open in the office of the utility model pump cover,
Fig. 6 is the structural representation of the utility model impeller,
Fig. 7 is the side view of the utility model impeller,
1 expression motor among the figure, motor be connected support 2 and interfix, motor shaft passes the connection support and links to each other with impeller 3, motor shaft has a mechanical seal 4 with being connected between the support, the one side of impeller is enclosed type, another side has a circle runner, blade 5 connects axioversion 40 degree--and 80 degree involute formulas are embedded on the impeller, pump cover 6 is fixed on and connects on the support, the end face that end face of pump cover and impeller have a circle runner matches, runner with impeller on pump cover has a circle horseshoe type runner 7 relatively symmetrically, in the inboard of runner one group of dentation seal ring 9 that coincide is mutually arranged, and one group of dentation seal ring 8 that coincide is mutually arranged in the outside of runner, one inlet hole 11 and an exit orifice 10 are arranged on pump cover, between enterprising oral pore of pump cover and exit orifice is platform 12, and liquid can only be entered from inlet hole, flows out from exit orifice.
Claims (2)
1, a kind of boiler feed water peripheral pump, comprise motor, impeller, connect support and pump cover, it is characterized in that: motor be connected support and interfix, motor shaft passes the connection support and links to each other with impeller, motor shaft has a mechanical seal with being connected between the support, the one side of impeller is enclosed type, another side has a circle runner, blade is embedded on the impeller by an angle involute of axioversion formula, pump cover is fixed on and connects on the support, the end face that end face of pump cover and impeller have a circle runner matches, runner with impeller on pump cover has a circle horseshoe type runner relatively symmetrically, at runner inside and outside one group of dentation seal ring that coincide mutually being arranged respectively, an inlet hole and an exit orifice are arranged on pump cover, is platform between enterprising oral pore of pump cover and exit orifice.
2, a kind of boiler feed water peripheral pump according to claim 1 is characterized in that: blade 5 is embedded on the impeller by axioversion 40-80 degree involute formula.
