Description
Technical field
The utility model relates to suction booster technical field, is specially a kind of high inlet pressure inter-section booster.
Background technique
Accompanying drawing 1 is the structural representation of the inter-section booster of prior art, inter-section booster comprises in the 8 millimeters thick pump housings 0.1, the pump housing 0.1 being provided with on pump cover 0.2, pump cover 0.2 and is provided with bearing housing 0.3, bearing housing 0.3 is provided with the pump shaft 0.5 that the diameter of axle is 45 millimeters, and the bearing 0.4 also comprised through 45 millimeters in two is arranged on bearing housing 0.3.
Some inter-section booster in RO (anti-penetration wastewater disposal) system of prior art, its lift is not necessarily very high, but it is even higher that inlet pressure usually can reach 10-50BAR according to technological requirement, and conventional pumps inlet pressure is generally limited within 10BAR.
For addressing this problem, client is often according to self-demand, especially supercharging pump structure is customized, by changing pump case thickness, the mode calculating voltage withstand class and configuration angular contact ball bearing meets inlet pressure, and possibility structure is ever-changing in different environment, is neither suitable for volume production and also improves user cost.
Model utility content
The utility model provides a kind of import voltage withstand class to reach 50BAR for above technical problem and can carry the high inlet pressure inter-section booster of additional axial force.
In order to achieve the above object, the technical solution of the utility model is: a kind of high inlet pressure inter-section booster, and comprise the pump housing, pump cover, bearing housing and pump shaft, described pump cover is arranged on the pump housing, and bearing housing is connected with pump cover, and described pump shaft is arranged on bearing housing; It is characterized in that: described pump housing thickness is 18 millimeters, also comprise deep groove ball bearing and two angular contact ball bearings, on the left of described bearing housing, deep groove ball bearing is installed, two angular contact ball bearings are installed on the right side of described bearing housing.
Can find out that this practical tool has the following advantages according to such scheme: such design can make suction booster import voltage withstand class reach 50BAR, and cost performance is higher, and described pump housing thickness is 18 millimeters; Adopt precision casting process to make water passage surface smooth, improve the overall resistance to pressure of pump case further.Not only efficiency is high, and operates steadily; In addition, the combination bearing of employing is fixed and can be carried certain axial force, and system cloud gray model is more steady.Run safer under high inlet pressure system condition, reliably.
As improvement, described two angular contact ball bearings are by being combined and installed together back-to-back; Bearing capacity is comparatively large, can bear bi-directional axial load simultaneously, have larger flexural rigidity.
As improvement, described pump shaft diameter is 70 millimeters; Pump shaft is comparatively thick, adopts less shaft extension cantilever ratio, improves the Rigidity and strength of pump shaft, thus the life-span of prolonged mechanical sealing and bearing.
As improvement, described pump shaft and pump cover adopt cartridge mechanical seal; Improve the stability of system cloud gray model.Mechanical seal, axle sleeve, gland are combined into an entirety, only need stationary gland, axle sleeve during installation, take off positioning block.Easy for installation, eliminate and the bad imbalance impact caused rotor is installed.
As improvement, described pump cover is also provided with pressure release axle sleeve; Because pump inlet pressure is comparatively large, utilize the gap length of pressure release axle sleeve and impeller rear-wheel hub to regulate pressure release, without compression shock in guarantee mechanical seal operation process, improve mechanical seal chamber and pump body global reliability.
