Technical Field
The utility model relates to a corrosion-resistant vacuum pump impeller of integral type belongs to corrosion-resistant vacuum pump technical field.
Background
The vacuum pump impeller is the major component of vacuum pump, the quality of vacuum pump has directly been decided to the good or bad of its quality and effect, under some special environment, the vacuum pump impeller needs inseparable lock to carry out work on the pump shaft, current vacuum pump impeller and the axle sleeve of pump shaft separately design, lead to and pump shaft and impeller between have the clearance, often can flow in some medium, lead to the pump shaft corruption, the impeller often contacts with corrosive liquid simultaneously, lead to the impeller to be corroded easily, need often to change.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the above-mentioned defect that current corrosion-resistant vacuum pump impeller exists, provide a corrosion-resistant vacuum pump impeller of integral type, simple structure, reasonable in design.
The utility model discloses an adopt following technical scheme to realize:
the integrated corrosion-resistant vacuum pump impeller comprises an assembling portion, wherein a base body portion is arranged at the lower portion of the assembling portion, a plurality of impeller blades are uniformly arranged on the outer side of the base body portion, the assembling portion, the base body portion and the impeller blades are integrally designed, the inner side of the assembling portion is arranged in a conical shape and is communicated with a shaft cavity in the middle of the base body portion, a shaft sleeve fixedly connected with the shaft cavity is arranged at the lower portion of the shaft cavity, and a shaft sleeve fixedly connected with the shaft cavity is arranged at the lower portion of the shaft cavity.
Further preferably, the outer side of the top of the impeller blade is provided with an upper connecting cover, and the outer side of the bottom of the impeller blade is provided with a lower connecting ring. The impeller blade is fixed between upper connection cover and lower go-between, increases the intensity of impeller blade, and the upper connection cover is inboard slope setting, and the suit portion of being convenient for installs better, and intensity is also higher simultaneously.
Further preferably, the tangential angle between the impeller blade and the outer ring of the base body part is 40-60 degrees. Can better drive the liquid inside to flow when rotating, thereby generating stable vacuum.
Further preferably, the sleeving part, the impeller blades, the upper connecting cover, the lower connecting ring and the base body part are all made of phenolic fiber composite materials; the outer side of the sleeving part is provided with a groove convenient to mount. The vacuum pump is clamped on the vacuum pump through the groove, the impeller can be effectively prevented from being corroded by the phenolic fiber composite material, the application range of the vacuum pump is wider, and the vacuum pump is suitable for places with corrosive liquid.
The utility model has the advantages that:
(1) the integrated corrosion-resistant vacuum pump impeller is provided with the sleeving part, and is buckled on the vacuum pump main shaft through the conical design on the inner side of the sleeving part, so that the integrated corrosion-resistant vacuum pump impeller is tightly clamped on the vacuum pump main shaft and is more closely matched with the vacuum pump main shaft;
(2) corrosion-resistant vacuum pump impeller of integral type, impeller blade, base part, suit portion integral type design, through mould casting shaping, can be so that impeller bulk strength is higher, difficult quilt is destroyed.
(3) The sleeving part, the impeller blades, the upper connecting cover, the lower connecting ring and the base body part are all made of phenolic fiber composite materials, the phenolic fibers can better resist weak acid and weak base, the phenolic fibers are used as main raw materials, and the manufactured impeller has better corrosion resistance and is more suitable for being applied to a corrosion-resistant vacuum pump.
