Precautions for installation of long-axis submerged pump
Axial thrust bearing method:
1) When the water pump is driven by an ordinary vertical motor, the weight and axial thrust of the water pump rotor are borne by the thrust bearing installed on the upper part of the water pump.
2) When the pump is driven by a vertical motor with thrust bearings, the weight and axial thrust of the pump rotor are borne by the thrust bearings in the motor.
3) When the water pump is driven by a right angle gear box, the weight and axial thrust of the water pump rotor are borne by the thrust bearing installed in the right angle gear box.
Thrust bearing lubrication: Thrust bearings are generally lubricated with thin oil (small pumps can also be grease lubricated). A cooling jacket can be provided on the outside of the bearing body, and cooling oil temperature can be cooled by cooling water.
Guide bearing lubrication method: self-lubrication: If the medium delivered by the pump is a clean liquid, the guide bearing can be directly lubricated with the medium delivered. External pressure water lubrication: If the medium delivered by the pump contains a small amount of impurities, clean pressure water needs to be connected from the outside to lubricate (the pump has a self-closing sealing system. After the pump is stopped, the self-closing sealing system can prevent impurities from entering. Guide bearing).
Installation method: Generally, the pump unit is installed on the same base layer.
Water outlet location: Under normal circumstances, the water outlet is located above the base layer, if the user needs it can also be located below the base layer.
Construction hoist is vertical transport machinery driving by pinion and rack, mainly used on construction site for transportation of personal and materials. As a permanent or sub-permanent external elevator, it also applies to store house, dock, high tower, high chimney, etc.
There are single cage and double cages hoist. According to the need gets rid of one cage of double cages the hoist will be changed to single cage hoist. SC Construction Hoist is equipped with reliable electrical and mechanical safety device. It is efficient and safety vertical transporting equipment.
BQ supplying all kinds of construction hoist spare parts, including Construction Hoist Mast Section, Passenger Hoist Cage, Construction Hoist Anchorage Frame, Anti Fall Safety Device, Construction Hoist Overload Protector, Construction Hoist Reducer, Sliding Contact Line, Construction Hoist Motor, Passenger Hoist Rope Pulley, Construction Hoist Roller, Electromagnet Brake, etc.
