Installation and start-up of BRY air-cooled high-temperature centrifugal pump

The vertical motor of BRY air-cooled high-temperature centrifugal pump is fixed to the motor seat with bolts, and is directly transmitted to the pump through elastic couplings, pump body, intermediate pipe, pump frame, outlet pipe, and pipe flange. It is connected by bolts and fixed on the bottom plate. The entire pump is installed on the container through the bottom plate. The axial and radial forces of the pump, including the water pressure generated during pump operation, the weight of the impeller and rotor, etc., are all composed of one-way thrust ball bearings and single row radial ball bearings installed in the bearing box; And the sliding guide shaft bears the normal operation of the pump. The bearings are lubricated with butter, and the guide bearings are lubricated with the conveyed liquid. Therefore, during operation, the liquid level is higher than the impeller line. If the length L of the container is different, it can be further divided into structures with intermediate guide bearings and structures without intermediate guide bearings

BRY air-cooled high-temperature centrifugal pump is made into various submerged lengths suitable for different working conditions based on the length of the container (usually 0.5 to 5.5m). The working part is submerged in the liquid, and the axial and radial forces generated by the pump operation are supported by rolling bearings and sliding bearings respectively; Therefore, the operation is quiet and noise free. The shaft seal has no liquid splashing phenomenon., According to the temperature of the medium used by the user, there is a cooling system at the sliding seal, which uses cooling water to take away heat

The BRY air-cooled high-temperature centrifugal pump should be started with the suction and discharge stop valve fully open to prevent overload or suction

Although the BRY air-cooled high-temperature centrifugal pump has dry suction capacity, it prevents dry rotation and scratches the working surface

If the pump needs to be started when the oil temperature is very low or the viscosity is very high, the BRY air-cooled high-temperature centrifugal pump should be started with the suction and discharge valves and bypass valves fully open, so that the load at the start of the pump is low until the prime mover reaches the rated speed, and then gradually close the bypass valve

When the bypass valve is opened, the liquid continuously circulates and flows in the pump with throttling. The more oil is circulated, the longer the circulation time, and the more severe the heat generation of the liquid, which may even cause damage to the pump due to high-temperature deformation, attracting attention
