Abstract
The invention discloses a water pump adjusting inner circulation flushing system which comprises a pump pressure water chamber high-pressure cavity, a sealing cavity and a sealing flushing groove connecting the pump pressure water chamber high-pressure cavity and the sealing cavity, wherein the pump pressure water chamber high-pressure cavity and the sealing cavity are formed in a pump shell. An adjusting device for controlling the aperture of the overflowing section of the sealing flushing groove is arranged on the pump shell. With the adjusting device, the water pump adjusting inner circulation flushing system can freely control flushing liquid in the sealing cavity, effectively control the flow of the flushing liquid in inner circulation of the water pump, therefore, leakage of the liquid in the sealing cavity can be reduced, the breakdowns of damage of sealing parts and the like are prevented, raised cost brought by using externally-connected flushing pipes can be reduced, and the requirements for reducing cost and improving flushing performance are met.
Description
Technical field
The invention belongs to water pump, be specifically related to a kind of water pump and can regulate interior circle irrigation system.
Background technique
Seal cage will produce a large amount of heats during water pump operation, and its cooling is undertaken by circle irrigation system in the water pump.In water pump in the circle irrigation system, the pumping chamber highly pressurised liquid flows in the Seal cage by the flushed channel on the pump cover, takes away the frictional heat, heat of stirring of Sealing etc., to the Sealing cooling, flows into the pump sump chamber afterwards and circulates.But because the pressure difference of pumping chamber under the different operating modes of pump of the same race, can not effectively regulate flushing liquid, often cause the fluid flow that flows in the Seal cage excessive, flushing liquid can not in time stay the resorption hydroecium to circulate, and hoard in Seal cage, cause liquid to leak from Seal cage; Even owing to the excessive infringement Sealing of flushing liquid flow, influence fault such as sealing property of sealing component.How effectively to control the flow of circulation flushing liquid in the water pump, be the problem demanding prompt solution of a key always.
Summary of the invention
The objective of the invention is the defective at the prior art existence, propose a kind of water pump and can regulate interior circle irrigation system, with the flow of circulation flushing liquid in effective control water pump, the generation that prevent damaging Sealing, influences faults such as sealing property of sealing component.
The technological scheme that realizes the object of the invention employing is as follows:
Water pump provided by the invention can be regulated interior circle irrigation system, comprise water-pumping chamber's hyperbaric chamber, the Seal cage that is located on the pump case and the groove of sealflushing that connects water-pumping chamber's hyperbaric chamber and Seal cage, be provided with the controlling device that groove overflow section aperture is sealflushed in control at described pump case.
Described controlling device is screw.
Beneficial effect of the present invention:
Pass through controlling device, can freely control the Seal cage flushing liquid, effectively control the flow of circulation flushing liquid in the water pump, just can reduce the leakage of Seal cage liquid, prevent faults such as Sealing infringement, also can reduce the cost that adopts external cleaning hose to bring and rise, reduce cost thereby reach, improve the flushing performance demands.
Further specify technological scheme of the present invention below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the controlling device schematic representation among the present invention.
Fig. 3 is the adjustment device work view among the present invention.
Embodiment
Referring to Fig. 1, Fig. 2, water pump provided by the invention can be regulated interior circle irrigation system, comprise the water-pumping chamber's hyperbaric chamber 1 that is located on the pump case 6, Seal cage 4 and connect water-pumping chamber's hyperbaric chamber 1 and Seal cage 4 sealflush groove 3, be provided with the controlling device 2 that groove 3 overflow section apertures are sealflushed in control at the described pump housing 6, described controlling device 2 is screw 201, pump case 6 is provided with screw 601 over against sealflushing groove 3, the top of screw 201 and screw 601 screw-thread fit, match with sealflushing groove 3 in the bottom of screw 201, the bottom of screw 2 also is provided with O-ring seals 202 and matches with screw 601 and prevent that liquid from leaking from screw 601.
During water pump operation, liquid flows to Seal cage 4 from water-pumping chamber's hyperbaric chamber 1 by sealflushing groove 3, finally flows to suction chamber 5, can regulate the size that flows to the fluid flow of Seal cage 4 from water-pumping chamber's hyperbaric chamber 1 by controlling device screw 2.When needs are regulated the fluid flow of sealflushing in the groove 3, can realize by turning screw 201, when reducing flow as need, tighten screw 201 and get final product (referring to Fig. 3), only need unscrew screw 201 otherwise increase flow.
Claims (2)
1. a water pump can be regulated interior circle irrigation system, comprise water-pumping chamber's hyperbaric chamber, the Seal cage that is located on the pump case and the groove of sealflushing that connects water-pumping chamber's hyperbaric chamber and Seal cage, it is characterized in that being provided with the controlling device that groove overflow section aperture is sealflushed in control at described pump case.
2. water pump according to claim 1 can be regulated interior circle irrigation system, it is characterized in that described controlling device is screw.
