When the pump housing and pump cover assembly connection, positioning convex ring on pump housing connection dish front end face overlaps sealing ring, positioned by positioning convex strip, positioning convex ring is plugged in the internal ring of pump cover rear end cap, sealing ring is tightly disposed between positioning convex ring outer wall and internal ring inwall, grafting location is convenient, and connection sealing is good.Then pass through trip bolt the pump housing and pump cover to be fastened together. Strengthen raised line and considerably increase the bonding strength of the pump housing. This draining pump pump housing and pump cover attachment structure ensure that bonding strength between the pump housing and pump cover, connect reliable, good airproof performance, and are linked and packed conveniently, and efficiency of assembling is high.
As preferably, positioning convex ring outer wall is step-like structure, and sealing ring is socketed on the outer wall of positioning convex ring path part. Internal ring inwall opening is inner small and outside big two-stage step cavernous structure, and sealing ring is connected on internal ring large diameter portion inwall. This structure arranges the setting being easy to sealing ring, it is ensured that sealing property.
As preferably, rotor assembly mounting cylinder front opening position is provided with reaming, and reaming inwall is provided with the stopper slot of a ring shape. Reaming is provided with a circle chamfering towards the front opening edge of connection dish. Reaming and chamfering are easy to the mounting arrangements of rotor, and stopper slot is easy to rotor installation location.
As preferably, outer shroud outer wall being equipped with outwardly arc strengthen projection with joint pin correspondence position, joint pin two side is equipped with outwardly arc reinforcement. Strengthen the protruding bonding strength adding the pump housing and pump cover with reinforcement.
Compared with prior art, the beneficial effects of the utility model are: the draining pump pump housing and pump cover attachment structure ensure that bonding strength between the pump housing and pump cover, connect reliable, good airproof performance, and are linked and packed conveniently, and efficiency of assembling is high.
