    • A cooling or heating fluid circulation system of the double-supported centrifugal pump, comprises a left shaft sleeve and a right shaft sleeve which are sleeved on the periphery of the pump shaft, a first left sealing gland and a second left sealing gland are sleeved on the periphery of the left shaft sleeve via a left outside stationary sealing ring, a left outside rotating sealing ring and a left inside stationary sealing ring respectively, a first right sealing gland and a second right sealing gland are sleeved on the periphery of the right shaft sleeve via a right outside stationary sealing ring, a right outside rotating sealing ring and a right inside stationary sealing ring respectively; a heat exchange fluid circulation channel, which is formed among the first left sealing gland, the second left sealing gland, the left shaft sleeve, the pump shaft, the right shaft sleeve, the first right sealing gland and the second right sealing gland, is connected with an external heat exchanger via an external channel; the heat exchange fluid therein is capable of rotating simultaneously with the rotating part and flowing along the axial direction of rotating part. The present invention is capable of directly cooling or heating the rotating parts which are most in need of cooling or heating, thus the temperature of the rotating parts can be kept in a certain range.

    • A cooling or heating fluid circulation system of a cantilevered centrifugal pump, comprises a pump shaft, one end of which is connected with a vane wheel, a shaft sleeve sleeved on the periphery of the pump shaft, a left sealing gland and a right sealing gland, which are sleeved on the periphery of the shaft sleeve, are connected in sequence from one side of the vane wheel along the axial direction of the shaft sleeve; the gap between the left sealing gland and the said shaft sleeve is arranged with an inside rotating sealing ring fixed with the shaft sleeve and an inside stationary sealing ring fixed with the left sealing gland, an outside rotating sealing ring fixed with the shaft sleeve and an outside stationary sealing ring fixed with the right sealing gland are arranged in the gap between the right sealing gland and the shaft sleeve and away from the left sealing gland; a flow-restricted ring is arranged between the inner peripheral surface of the right sealing gland and the shaft sleeve; and a heat exchange fluid circulation channel, which is formed among the gap between the right sealing gland and the shaft sleeve, the shaft sleeve and the pump shaft, is connected with an external heat exchanger via an external channel. The present invention is capable of directly cooling or heating the rotating parts which are most in need of cooling or heating, thus the temperature of the rotating parts can be kept in a certain range.

    • An auxiliary shaft seal flushing system of a centrifugal pump and an axial flow pump, comprising a main running pump and a standby pump which are provided with a same shaft seal flushing system respectively, the shaft seal flushing system of the main running pump and that of the standby pump being connected in parallel to form a common shaft seal flushing system. The common shaft seal flushing system comprises: a first outlet pipe connected to an outlet of the main running pump and a first switch valve provided on the first outlet pipe for switching the flushing fluid, a second outlet pipe connected to an outlet of the standby pump and a second switch valve provided on the second outlet pipe for switching the flushing fluid, and a first fluid guide pipe connected to the outlets of the first outlet pipe and the second outlet pipe; the outlet of the first fluid guide pipe is respectively connected to a flushing fluid inlet on a sealing gland of the main running pump by a third outlet pipe and connected to a flushing fluid inlet on a sealing gland of the standby pump by a fourth outlet pipe. The present invention can keep the parameters of the fluid material in sealed cavities of the main and standby pumps the same at all times.
