Abstract
The utility model discloses a non-load preventing corrosion-resistant pump. The non-load preventing corrosion-resistant pump comprises a pump case, wherein a pump cover is arranged on one side of the pump case, an impeller is installed inside the pump cover and the pump case in a rotating mode, one end of a main shaft of the impeller penetrates through the pump cover, a mechanical seal is arranged on the outer wall of one end, arranged outside the pump cover, of the main shaft, a cover cap is fixedly installed outside the mechanical seal, a support is fixedly installed outside the cover cap, and a gap is reserved between the support and the cover cap. The non-load preventing corrosion-resistant pump is simple in structure and convenient to use, and achieves the using effect of non-load prevention.
Description
Technical field
The utility model relates to a kind of pump equipment, specifically a kind of anti-corrosive pump of preventing idle load.
Background technique
Anti-corrosive pump is external mounted machine envelope because of mechanical seal, mostly for nonmetallic material, makes rotor part when zero load: impeller, pump cover, mechanical seal, very easily lost efficacy.
The model utility content
The utility model purpose is to provide and a kind ofly makes the temperature temperature rise of mechanical seal place normal, reaches the anti-corrosive pump of preventing idle load of the using effect of preventing idle load.
The utility model technical solution problem provides following scheme:
A kind of anti-corrosive pump of preventing idle load, comprise pump case, it is characterized in that: a side of described pump case is provided with pump cover, described pump cover and pump case inner rotation are equipped with impeller, main shaft one end of described impeller passes pump cover, and is provided with mechanical seal on the end spindle outer wall outside pump cover, and described mechanical seal is installed with cover cap outward, described cover cap is installed with support outward, between described support and cover cap, leaves gap.
One end of described main shaft is through support.
The anti-corrosive pump of the utility model preventing idle load is by pump case, impeller, pump cover, mechanical seal, flushing combination, described flushing combination comprises that the component such as housing, support form, to add a flushing combination in the mechanical seal outside of anti-corrosive pump, first lead to sparge water before pump startup, sparge water is in the external refrigeration circulation of mechanical seal, when pump is unloaded, because of the cool cycles that sparge water is arranged, make the temperature temperature rise of mechanical seal place normal, reach the using effect of preventing idle load.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, a kind of anti-corrosive pump of preventing idle load, comprise pump case 1, a side of described pump case 1 is provided with pump cover 2, and described pump cover 2 is equipped with impeller 3 with pump case 1 inner rotation, main shaft 4 one ends of described impeller 3 are through pump cover 2, and be provided with mechanical seal 5 on the end spindle outer wall outside pump cover 2, the outer cover cap 8 that is installed with of described mechanical seal 5, the outer support 6 that is installed with of described cover cap 8, leave gap 7 between described support 6 and cover cap 8, an end of described main shaft 4 is through support 6.
