Abstract
The utility model discloses a heat insulation high-pressure Roots blower, pertaining to a blower. The heat insulation high-pressure Roots blower structurally comprises a wallboard and bearing chambers. The wallboard is composed of an oil box connecting wallboard and a blower body connecting wallboard. The blower body connecting wallboard and the bearing chambers are separate. The two bearing chambers of the support shafts are separate with the blower body connecting wallboard and are linked through support ribs which are provided with heat dissipation holes. Compared with prior art, the heat insulation high-pressure Roots blower effectively prevents the heat of the body of the Roots blower from being transferred to the bearings, reduces making cost, saves cooling water and reduces the operation cost of the blower; therefore the heat insulation high-pressure Roots blower has good popularization and application values.
Description
Technical field
The utility model relates to a kind of blower, especially a kind of insulation type high pressure roots blower.
Background technique
Because the expansion of technological progress and application area, Roots blower unit working pressure develops into present 0.1MPa by original 0.06MPa.Along with increasing of head pressure, pressurized gas produces a large amount of frictional heats in the Roots blower body, can reach 120 ℃, the high temperature that produces passes to bearing by the wallboard of body both sides, the working life and the Roots blower proper functioning of bearing have been influenced, traditional solution is that Roots blower body and both sides wallboard are designed to sandwich structure, and is middle with the water cycle cooling, cuts off the thermal source that makes bearing temperature rise.But employing sandwich structure, manufacture cost height, waste water resource.At present, good solution is not also arranged.
The model utility content
Technical assignment of the present utility model is to provide a kind of insulation type high pressure roots blower at above-mentioned deficiency of the prior art, and this insulation type high pressure roots blower has and reduced manufacture cost, has saved the characteristics of cooling water.
The technological scheme that its technical problem that solves the utility model adopts is: it comprises wallboard and bearing chamber, wallboard comprises that fuel tank connects wallboard and body connects wallboard, described body connects wallboard and bearing chamber adopts separated type, two bearing chambers of back shaft and body are connect wallboard keeps apart, middle supporting rib with the band radiation hole connects, and the internal cavities between the described supporting rib cuts off the conduction of heat.
Insulation type high pressure roots blower of the present utility model is compared with prior art, has following outstanding beneficial effect: effectively overcome in the Roots blower body heat to the transmission of bearing, reduce manufacture cost, saved cooling water, reduced the characteristics such as operating cost of blower.
Description of drawings
Accompanying drawing 1 is the main TV structure schematic representation of insulation type high pressure roots blower;
Accompanying drawing 2 is that the A-A of insulation type high pressure roots blower is to structural representation;
Description of reference numerals: 1, bearing chamber, 2, fuel tank connects wallboard, 3, supporting rib, 4, body connects wallboard.
Embodiment
Explain below doing with reference to Figure of description 1,2 pairs of insulation type high pressure roots blowers of the present utility model of accompanying drawing.
Insulation type high pressure roots blower of the present utility model, its structure comprises wallboard and bearing chamber 1, described wallboard comprises that fuel tank connects wallboard 2 and body connects wallboard 4, described body connects wallboard 4 and bearing chamber 1 adopts separated type, two bearing chambers 1 of back shaft are kept apart with body connection wallboard 4, middle supporting rib 3 with the band radiation hole connects, and the internal cavities between the described supporting rib 3 has cut off in the body heat to the conduction of bearing chamber 1.
Insulation type high pressure roots blower of the present utility model has overcome effectively that heat is to the transmission of bearing in the Roots blower body, and structure can replace traditional sandwich structure fully.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
