Description

TECHNICAL FIELD

[0001] The utility model relates to a centering adjusting device, concretely relates to a detachable high temperature submersible pump centering adjusting device which is more reasonable and reliable in structure, can be shared by multiple pumps with one set of device, and reduces production cost. BACKGROUND

[0002] The high temperature submersible pump is specially used for conveying various media under high temperature conditions, such as various high temperature molten salts, liquid metals, organic and inorganic compounds, etc. The temperature of such media can be as high as 500 DEG C or above.

[0003] Due to the high temperature medium, the rotation center of the pump shaft connected by the motor coupling of the high temperature submersible pump must be strictly centered. The coupling must be aligned and centered during installation, otherwise the coupling will generate a large stress, seriously affecting the normal operation of the pump, and even damaging the pump. Therefore, the requirement for the centering of the high temperature submersible pump is very strict.

[0004] The original high temperature submersible pump whole centering structure mainly comprises a discharge seat 1', a motor support 2', a pump coupling 3', an intermediate section 4', a motor coupling 5', bolts 6', a motor 7', an adjusting nut 8', adjusting bolts 9', an adjusting block 10', and a pump shaft 11'. The lower end of the motor support 2' is connected to the discharge seat by bolts, the upper end of the motor support 2' is fixedly connected to the motor 7' by the bolts 6', the adjusting nut 8' is welded on the adjusting block 10', the adjusting block 10' is welded on the motor support 2', and the pump is adjusted and centered by the adjusting bolts 9'.

[0005] From Figure 1 It can be seen that the pump centering adjusting device of the original structure is a welded structure, the adjusting nut 8' is welded on the adjusting block 10', the adjusting block 10' is welded on the motor support, and the pump is adjusted and centered by the adjusting bolts 9'. The device is a traditional centering adjusting structure, which can basically meet the centering requirement of the pump. However, since it is a welded structure, the device can only adjust and center a single pump. Since multiple pumps are used on site, each pump needs to be equipped with a centering adjusting device, which lacks universality, resulting in increased production cost. In addition, the welded structure adjusting device is distributed in four directions around the flange of the motor support 2', and the device is easy to be damaged by knocking during transportation or lifting, affecting the overall appearance of the pump.
