自吸式大流量离心泵是一种通用机械,通常这种自吸式大流量离心泵工作效率高,电机将水吸入时会有大量水残留在泵体内,冬天温度零下,水易结冰,水结冰后体积变大,容易将不锈钢泵壳惊损甚至胀破。目前,市场上的自吸式大流量离心泵没有相应的保护措施,泵壳容易裂损,损耗较大。 
实用新型内容
针对现有技术存在的不足,本实用新型的目的在于提供一种防止水结冰冻裂泵体内储水部的自吸式大流量离心泵。 
为实现上述目的,本实用新型提供了如下技术方案:一种自吸式大流量离心泵,包括泵体和电机,所述泵体包括进水口、出水口、叶轮和储水部,所述叶轮在储水部中,所述叶轮与转轴连接转动,所述储水部上设有凹槽和缓冲层,所述缓冲层与储水部固定连接,所述缓冲层覆盖凹槽开口,所述凹槽内设有气囊,所述气囊与凹槽大小相适配。 
通过采用上述技术方案,冬天温度零下水结冰体积变大,所述气囊受挤压,气囊压缩,缓冲冰胀大产生的压力,保护不锈钢泵壳,气囊仍有较强刚度,冰化水后,气囊可恢复原样,所述缓冲层由吹塑弹性材料吹塑成型,有较强的缓冲能力,保护不锈钢泵壳不被胀裂,减少损耗。 
本实用新型进一步设置为:所述气囊呈圆柱状,侧壁有多条环状 V 型槽形成锯齿形折叠纹。 
通过采用上述技术方案,所述气囊受挤压,锯齿形折叠纹状的气囊回缩,在气囊压缩后期,锯齿形折叠纹状的气囊气袋中间 V 型槽两侧面向内合拢,气囊压缩,气囊仍有较强刚度。 
本实用新型进一步设置为:所述缓冲层为软质材料。 
通过采用上述技术方案,软质材料弹性好,强度高,使用寿命长,缓冲效果好。 
本实用新型进一步设置为:所述缓冲层通过密封胶与储水部固定。 
通过采用上述技术方案,密封胶由环氧树脂、酚醛树脂、有机硅树脂和不饱和聚酯树脂组成,可保证机械强度的稳定可靠,绝缘密封。 
本实用新型进一步设置为:所述气囊为弹性材料吹塑成型。 
通过采用上述技术方案,弹性材料吹塑成型的气囊具有弹性好,耐高温,耐老化,耐高压,强度高、使用寿命长的优点。 
本实用新型进一步设置为:所述气囊内为氮气。 
通过采用上述技术方案,氮气为惰性气体,不易发生爆炸,且成本低。
