Abstract
The utility model relates to a Routs blower end cover integral-type cast fully-closed water jacket cooling structure, which is characterized in that an end cover (1) is of an integral-type cast structure, wherein cooling water cavities (2) which surround a bearing holder (6) and are communicated with each other are arranged inside the end cover (1), one side of the end cover (1) is provided with awater inlet (4) which is communicated with the cooling water cavities (2), the other side of the end cover (1) is provided with a water outlet (5) which is communicated with the cooling water cavities (2), and the water inlet (4) is larger than the water outlet (5), so an appropriate pressure is formed inside the cooling water cavity (2), and the entire cooling water cavity (2) is fulfilled withcooling water to form a water cycling cooling structure. A sealing cover plate is arranged on a cast craftwork hole (3) on the end cover (1). The Routs blower end cover integral-type cast fully-closedwater jacket cooling structure has obvious cooling effect, thoroughly improves the high-pressure work condition of the Routs blower, and greatly improves the working efficiency of the Routs blower while ensuring the processing efficiency.
Description
Technical field
The utility model relates to the roots blower technical field, and is specifically a kind of when the roots blower high pressure is worked (be generally 90KPa or more than), for the roots blower end cap integrated type that solves high temperature rise is cast totally-enclosed water jacket cooling structure.
Background technique
General roots blower commonly used is a natural air cooling when working below 90KPa pressure, better in low pressure area natural air cooling effect, when reaching approaching or surpassing 90KPa, rising along with pressure, temperature rise sharply raises, the normal working that causes the expansion change blower fan of material, especially the influence of bearing and Sealing is bigger, when so some blower fan is worked with upward pressure at 90KPa, take the interior water cycle cooling of end cap (wallboard), general in the market structure has two kinds, and first kind for boring the water cycle hole around bearing support, this method is because the water cycle amount is minimum, and cooling effect is very unobvious.Another kind of for end cap is cast as the water cooling cavity, be inlaid into bearing support during the assembling of processing back, though this structure quantity of circulating water is big, cooling effect is also apparent in view, and still, processing is too complicated, and cannot say for sure to demonstrate,prove machining accuracy,, have the potential possibility of seepage owing to be the fitting tight water-bound.
Summary of the invention
Deficiency when the utility model is worked in order to overcome above-mentioned high pressure on the water-cooling structure of roots blower provides a kind of roots blower end cap integrated type to cast totally-enclosed water jacket cooling structure.
The technical solution of the utility model is:
A kind of roots blower end cap integrated type is cast totally-enclosed water jacket cooling structure, end cap is the integrated type cast structure, the inside of described end cap is provided with the cooling water chamber that is interconnected around bearing support, end cap one side is provided with the water intake that is communicated with cooling water chamber, the end cap opposite side is provided with the water outlet that is communicated with cooling water chamber, and water intake is greater than water outlet, makes to form suitable pressure in the cooling water chamber, guarantee that cooling water is full of whole cooling water chamber, form water circulation cooling structure.
Casting technique hole on the described end cap is provided with sealed cover.
The beneficial effects of the utility model are:
Roots blower end cap integrated type of the present utility model is cast totally-enclosed water jacket cooling structure and has not been avoided the too small cooling effect of the boring water yield good and embedded bearing seat form technology is too complicated and have the possibility of potential seepage.Cooling effect is obvious especially, has thoroughly improved roots blower high pressure operating mode, when guaranteeing machining accuracy, has improved the working efficiency of roots blower greatly.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is an A-A direction sectional view among Fig. 1.
Fig. 3 is a F-F direction sectional view among Fig. 2.
Among the figure: 1 is that end cap, 2 is that cooling water chamber, 3 is that casting technique hole, 4 is that water intake, 5 is water outlet.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of roots blower end cap integrated type is cast totally-enclosed water jacket cooling structure, end cap 1 is the integrated type cast structure, the inside of end cap 1 is provided with the cooling water chamber 2 that is interconnected around bearing support 6, end cap 1 one sides are provided with the water intake 4 that is communicated with cooling water chamber 2, end cap 1 opposite side is provided with the water outlet 5 that is communicated with cooling water chamber 2, and water intake 4 is greater than water outlet 5, makes to form suitable pressure in the cooling water chamber 2, guarantee that cooling water is full of whole cooling water chamber 2, form water circulation cooling structure.
In conjunction with Fig. 1,2,3, the space that the bottom of end cap 1 and upper end and bearing support 6 are encircled a city forms cooling water chamber 2, and except that water intake 4 and water outlet 5, the casting technique hole 3 that is connected with cooling water chamber 2 of end cap 1 upper end seals cover plate after machining.Cooling water enters cooling water chamber 2 by water intake 4, and water outlet 5 forms suitable pressure less than water intake 4 in cooling water chamber 2, guarantee that cooling water is full of whole water cavity, is flowed out by water outlet 5 again, forms the water cycle cooling.As long as just can play best cooling effect, make whole blower fan work under the good work condition state through test, promoted the working pressure and the complete machine working efficiency of blower fan effectively according to the suitable flow of fan condition control.
Claims (2)
1, a kind of roots blower end cap integrated type is cast totally-enclosed water jacket cooling structure, it is characterized in that end cap (1) is the integrated type cast structure, the inside of described end cap (1) is provided with the cooling water chamber (2) that is interconnected around bearing support (6), end cap (1) one side is provided with the water intake (4) that is communicated with cooling water chamber (2), end cap (1) opposite side is provided with the water outlet (5) that is communicated with cooling water chamber (2), water intake (4) is greater than water outlet (5), make and form suitable pressure in the cooling water chamber (2), guarantee that cooling water is full of whole cooling water chamber (2), form water circulation cooling structure.
2, roots blower end cap integrated type according to claim 1 is cast totally-enclosed water jacket cooling structure, it is characterized in that the casting technique hole (3) on the described end cap (1) is provided with sealed cover.
