본 발명은 압력밸런스형 인라인용 엘피지 외장형 연료펌프에 관한 것으로서, 더욱 상세하게는 제 1 부싱과 제 2 부싱이 모터부의 모터축 양끝단부에 구비되도록 각각 본체의 내부에 설치됨으로써, 모터부의 회전시 하중을 분산 및 균등하게 배분할 수 있어 내구성이 향상되고, 상기 배출덮개의 내부면에 지지부가 돌출 형성되어 모터축의 끝단부가 지지되고, 상기 지지부의 결합홈에 제 1 부싱과 지지핀이 설치되어 모터축의 끝단부를 지지함으로써, 모터부의 회전시 전달되는 진동 등에 의해 모터축이 이탈 및 이탈에 따른 파손 등이 방지되어 내구성이 향상되며, 상기 펌핑부의 배출 플레이트에 압력밸런스홀이 형성되고, 상기 압력밸런스홀과 연통되는 가이드막 일단부에 압력유입홀이 형성됨으로써, 일반적으로 엘피지 연료가 유입되는 유입홀의 내부가 저압상태가 되어 상대적으로 이송홀의 내부가 고압상태가 되며 그로 인해 회전되는 캐리어의 중심 밸런스가 어긋남에 따라 캐리어가 흡입 플레이트와 배출 플레이트와 마찰되는 것을 압력밸런스홀을 통해 압력이 유입되어 캐리어의 회전 밸런스가 유지되고, 그로 인해 캐리어가 흡입 플레이트와 배출 플레이트와 마찰되는 것을 방지하여 내구성의 효율이 향상되는 특징이 있다. The present invention relates to a pressure balanced type in-line elbow external fuel pump, and more particularly, the first bushing and the second bushing are provided inside the main body so as to be provided at both ends of the motor shaft of the motor part, so that the load at the time of rotation of the motor part. Can be distributed and evenly distributed, and durability is improved, and a support part protrudes from the inner surface of the discharge cover to support the end of the motor shaft, and a first bushing and a support pin are installed in the coupling groove of the support to the end of the motor shaft. By supporting the part, the motor shaft is prevented from being separated and damaged due to vibration and the like transmitted by the rotation of the motor part, thereby improving durability, and a pressure balance hole is formed in the discharge plate of the pumping part, and communicates with the pressure balance hole. Since a pressure inlet hole is formed at one end of the guide membrane, the inside of the inlet hole into which the LLP fuel is generally introduced. The pressure inside the transfer hole becomes relatively high, and the inside of the transfer hole becomes a high pressure state. As a result, the carrier balances with the suction plate and the discharge plate as the center balance of the rotating carrier is shifted. The balance is maintained, ...

Pump arrangement

The invention relates to a pump arrangement (1), more particularly a magnetic clutch pump arrangement, comprising an inner chamber (11) formed by a pump housing (2) in the pump arrangement (1); a containment shell (10) which hermetically seals an enclosed chamber (12) with respect to the inner chamber (11) formed by the pump housing (2); an impeller shaft (13) that can be driven in rotation about an axis of rotation (A); an impeller (16) mounted on one end of the impeller shaft (13); an inner rotor (17) mounted on the other end of the impeller shaft (13); a drive motor (9); a drive shaft (20) that can be driven in rotation about the axis of rotation (A) by the drive motor (9); and an outer rotor (22) which is mounted on the drive shaft (20) and co-operates with the inner rotor (17); wherein the outer rotor (22) has a hub (23) and a first support element (28). According to the invention the outer rotor (22) has a hollow cylindrical portion (25) between the hub (23) and the first support element (28).

Submersible pump having frangible drive connection

A submersible motor pump assembly having an improved driving connection between the motor and pump. The motor shaft and pump shaft are disposed in end-to-end relation and a bolt extends through an axial passage in the pump shaft and the projecting end of the bolt is threaded in an axial opening in the end of the motor shaft. The outer or opposite end of the pump shaft is formed with a recess that communicates with the passage and the head of the bolt is fixed against rotation with respect to the pump shaft by a bolt retainer which is disposed with the recess. A shear pin interconnects the mating ends of the two shafts to provide a driving connection. The hand of the thread on the bolt is such that rotation of the motor shaft, after shearing of the shear pin, will cause the bolt to be unthreaded from the motor shaft to prevent locking up of the shafts.
