Abstract
The utility model provides a high temperature ventilation blower leak protection water cooling case, includes the box, the box is located between casing and the bearing box, the box cup joints on the main shaft, the upper end of box is provided with the water inlet, and the lower extreme of box is provided with the delivery port, be located to have cup jointed the sealing washer on the main shaft of box both sides, the sealing washer is hugged closely on the outer wall of box, its characterized in that: it has cup jointed water slinger on the inside main shaft of box to be located, water slinger hugs closely on the inner wall of box. The utility model discloses set up water slinger in the inside of box, through the coordination of water slinger with the sealing ring, can block effectively that high -pressure cooling water to box sealing performance's broken ring, has guaranteed the cooling efficiency of cooler bin effectively.
Description
Technical field
The utility model relates to fan manufacturing technology field, is specifically related to a kind of high temperature ventilator preventing water leakage cooler bin.
Background technique
High-temperature blower belongs to extraordinary blower fan, is specifically designed to workroom in high temperature, and its material has stronger high temperature resistant, barotolerance.High-temperature blower mainly contains: stainless steel resisting blower, transmission high-temperature blower, centrifugal high-temperature blower etc.High-temperature blower is widely used in the fields such as chemical engineering industry, oil, metallurgy, forging and stamping, electric power, nuclear power station, environmental protection.
High-temperature blower is because of its job specification (inside temperature reaches 300 ~ 700 DEG C) decision, operationally temperature is also very high for the main shaft of its inside, therefore need for main shaft arranges cooler bin specially, casing inner main axis heat of high temperature is prevented to be delivered in bearing housing, rolling bearing temperature in bearing housing is raised, thus affects the working life of rolling bearing.
The cooler bin of present stage is generally use water cooling case cooling main shaft, and cooling water enters from the water intake being positioned at casing upper end, then discharges from the drain opening being positioned at casing lower end.Due to the hydraulic pressure of the cooling water entered from water intake higher (0.2 ~ 0.3Mpa), will directly impact the seal ring being positioned at tank ends after entering casing, the time has been grown, and is easy to the breakage causing seal ring, cooling water is spilt from breakage spot, greatly affects the cooling effectiveness of cooler bin.
Summary of the invention
The purpose of this utility model is the defect and the deficiency that overcome existing technology, provides that a kind of structure is simple, the high temperature ventilator preventing water leakage cooler bin of good seal performance.
For realizing above object, technical solution of the present utility model is: a kind of high temperature ventilator preventing water leakage cooler bin, comprise casing, described casing is between casing and bearing housing, described casing is socketed on main shaft, the upper end of described casing is provided with water intake, the lower end of casing is provided with water outlet, the main shaft being positioned at casing both sides is socketed with seal ring, described seal ring is close on the outer wall of casing, it is characterized in that: the main shaft being positioned at box house is socketed with water holding ring, and described water holding ring is close on the inwall of casing.
Described seal ring and water holding ring adopt heat resistant and wear resistant to damage material and make.
The utility model arranges water holding ring in the inside of casing, by the coordination of water holding ring and seal ring, effectively can stop the broken ring of high-pressure cooling water to box sealing performance, effectively ensure that the cooling effectiveness of cooler bin.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: casing 1, casing 2, bearing housing 3, main shaft 4, water intake 5, water outlet 6, seal ring 7, water holding ring 8.
Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be described in further detail.
See Fig. 1, a kind of high temperature ventilator preventing water leakage cooler bin, comprise casing 1, described casing 1 is between casing 2 and bearing housing 3, and described casing 1 is socketed on main shaft 4, the upper end of described casing 3 is provided with water intake 5, the lower end of casing 3 is provided with water outlet 6, and the main shaft 4 being positioned at casing 1 both sides is socketed with seal ring 7, and described seal ring 7 is close on the outer wall of casing 1, the main shaft 4 being positioned at casing 1 inside is socketed with water holding ring 8, and described water holding ring 8 is close on the inwall of casing 1.
Because main shaft 4 works in high temperature environments, and be in high speed operation state all the time, be therefore socketed in the rubber material that seal ring 7 on main shaft 4 and water holding ring 8 adopt heat resistant and wear resistant to wipe and make.
During utility model works, after high-pressure cooling water enters from water intake 5, can first impact the water holding ring 8 be positioned on casing 1 inwall, even if water holding ring 8 causes breakage through long-term impacting with high pressure, stop due to the outer wall of casing 1 being also provided with seal ring 7, therefore cooling water still cannot spill from casing 1, thus improves quality and the working life of cooler bin.
Claims (2)
