Problems solved by technology

However, there are some unavoidable defects in reciprocating pumps: the plunger reciprocates, and the sealing performance cannot be guaranteed; the vibration is large, the noise is high; the flow rate is unstable; the reliability is poor and failures are frequent, so the reciprocating pump cannot meet the requirements of the space environment.
These three types of pumps all have certain disadvantages. The gap between the motor shaft and the impeller is mechanically sealed, which leads to a reduction in the life of the pump and a certain degree of leakage. The multi-stage impeller and gear pump lead to complex structures and increase the probability of failure.

Embodiment Construction

[0020] Such as figure 1 As shown, the present invention is a circulating filling pump for space on-rail filling, including a motor housing 1, a motor 2, a bolt A3, a gasket A4, a motor seat 5, a permanent magnet coupling 6, a permanent magnet 7, a gasket Sheet B8, bolt B9, outlet pipe 10, pump casing cover 11, clamp 12, impeller 13, bearing 14, pump casing 15, inlet pipe 16, hexagon socket bolt 17; motor 2 is fixed by motor base 5 with 3 bolts A3 On the motor casing 1, the motor casing 1 is in direct contact with the motor 2, which can quickly transfer the heat generated by the motor 2 to the motor casing 1, and transfer it to the pump casing 15 through the heat conduction of the motor casing 1, and finally use the pump casing 15 The internal fluid takes away the heat, so that the temperature of the motor 2 is kept constant, and the long-term operation of the motor 2 is ensured. The permanent magnet 7 cooperates with the clip 12 and the permanent magnet coupling 6 in an inter...

Abstract

The invention relates to a circulating refueling pump for on-orbit refueling in space. The circulating refueling pump comprises a motor shell (1), a motor (2), a motor base (5), a permanent magnet coupler (6), permanent magnets (7), an outlet tube (10), a pump shell cover (11), a hoop (12), an impeller (13), a bearing (14), a pump shell (15) and an inlet tube (16). The circulating refueling pump has the advantages of being small in size, light, high in reliability and low in specific speed.

Description

technical field [0001] The invention relates to a circulation filling pump, which is especially suitable for the circulation filling pump for space on-rail filling. Background technique [0002] With the urgent need of spacecraft space on-orbit refueling technology, especially the satellite on-orbit refueling technology is still in the development stage in our country, the circulating refueling pump is the core component of the on-orbit refueling system. my country's space circulation filling pump has no mature product application records. The circulating filling pump used in the on-rail filling system has a small flow rate and a high head, and the specific speed of the micro pump is low. When the design specific speed of the pump is low, vortex pumps or reciprocating pumps are generally used in engineering. However, reciprocating pumps have some unavoidable defects: the plunger reciprocates, and the sealing performance cannot be guaranteed; large vibration and high noise;...
