Abstract
Description
Technical Field
[0001] The invention relates to a siphon pump, which is a high-efficiency energy-saving pump. With the same power consumption, the flow rate and the head are larger than those of an axial flow pump. Background Art
[0002] The existing pump impeller is a spiral impeller, and there is a gap between the impeller and the pump casing; the fluid cannot be turned 90 degrees to be thrown out. This siphon pump uses a 1 / 4 arc surface impeller outer sleeve bearing and then sleeved on the pump casing. There is no gap between the impeller and the pump casing; it can turn 90 degrees to throw out the fluid.
[0003] The technical solution is: The 1 / 4 arc impeller can change the direction of the fluid by 90 degrees, using the power of rotation to turn the incoming fluid by 90 degrees and then throw it upward.
[0004] When installed vertically, the fluid is thrown vertically upward; when installed horizontally, the fluid is thrown forward by turning 90 degrees. High efficiency. Summary of the invention
[0005] The light-proof 1 / 4 arc curved impeller outer sleeve bearing with fan-shaped extension throws the fluid passage seal upward to form a siphon in the water (gas) inlet pipe.
[0006] The beneficial effects of the present invention are: The impeller outer sleeve bearing is then put on the pump housing, and there is no gap between the impeller and the pump housing. The fluid passage is sealed when it is thrown upward, and a siphon is formed in the inflow pipe. The fluid is thrown out at a 90-degree turn, which is highly efficient.

[0025] 1 / 4 arc curved blade, the inner wall is a 1 / 4 arc curved surface.
[0026] The 1 / 4 arc curved blades are provided with fan-shaped extensions, wherein the fan-shaped extensions block the front light-transmitting portions of a circle of 1 / 4 arc curved blades distributed in a circular array.
[0027] The entrance of the fan-shaped extension is chamfered and the edges are rounded. Implementation
[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] As shown in the attached picture.
[0030] A 1 / 4 arc curved impeller that can throw fluid vertically upward (or horizontally forward) determines the impeller shaft diameter, impeller height, and number of circles (the impeller may have one or more circles of blades) according to the needs of the application scenario; the light-transmitting portion of each circle of 1 / 4 arc curved blades evenly distributed in a circular array is shielded by a fan-shaped extension; the impeller is opaque when viewed from the front.
[0031] A large bearing slot is left on the outer ring of the impeller.
[0032] Leave a small bearing space on the impeller shaft.
[0033] A shaft hole for connecting the motor is reserved at the end of the impeller shaft.
[0034] The impeller is fitted with a large bearing.
[0035] The impeller shaft is sleeved with a small bearing.
[0036] Process the pump casing, leaving space for the large bearing position, large bearing retaining ring position, small bearing position, sealing ring position, sealing ring retaining ring position, inlet interface, outlet interface, and motor mounting hole.
[0037] After installing the impeller into the pump casing, secure it with a large bearing retaining ring.
[0038] Install the sealing ring.
[0039] Secure it with a sealing ring and retaining ring.
[0040] Fasten the motor to the base with bolts.
[0041] Connect the inlet pipe.
[0042] Connect the outflow pipe.
[0043] The water inlet is equipped with a foot valve, flower basket, or check valve.
[0044] Install a pressure switch at the outlet to change into a booster pump.
[0045] When used for the first time, fill the inlet pipe with fluid.
[0046] After the fluid has soaked through the impeller, the gas in the inlet pipe can be emptied after a period of startup, completing self-priming and working normally.
[0047] The pump casing is a tee (including oblique tee and straight tee). When the pump casing is a straight tee, the inflow pipe should be bent upward with an elbow before being connected to the water source.
[0048] The outlet interface uses a large-to-small straight-through reducer, and the outlet pipe diameter is consistent with the impeller diameter.
[0049] The power consumption remains unchanged. The more blades there are, the greater the flow rate and the smaller the lift. The fewer blades there are, the smaller the flow rate and the greater the lift.
[0050] High pressure siphon pump, the impeller is double blade. Can be used as a gas compressor.
[0051] When conveying fluid horizontally, the pump is installed horizontally and the pump casing is a straight tee.
[0052] Those skilled in the art can understand that the modules or processes of the embodiments are not necessarily necessary to implement the present invention.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
