Precautions for vertical suspended pumps mainly include the following aspects:
Equipment inspection and tool preparation: Before hoisting, conduct a comprehensive inspection of the vertical pump to ensure that the pump body, bearings, motors, inlet and outlet pipes, etc. are not damaged, deformed or cracked. At the same time, prepare necessary hoisting tools, such as wire ropes, hooks, pulleys, hoisting belts, etc., and check their integrity.
Site preparation: Ensure that the hoisting site is flat, solid, and free of obstacles, and there should be obvious warning signs in the hoisting area.
Personnel training: Provide safety education and operation training for personnel involved in hoisting to ensure that they are familiar with hoisting operating procedures and safety precautions.
Hoisting steps:
Positioning: Determine the hoisting point according to the installation position of the vertical pump to ensure that the hoisting point is stable and reliable.
Hook: Pass the wire rope through the hook, adjust the rope length, and ensure that the hook is firmly hung on the hoisting hole or lifting lug of the vertical pump.
Trial lifting: Perform a trial lifting before formal lifting to check whether the lifting system is stable and whether the lifting equipment is working properly.
Lifting: Lift slowly and observe the moving direction and speed of the vertical pump to ensure that it moves smoothly.
Turn: During the lifting process, if you need to turn, do it slowly to avoid tilting or damage to the equipment due to excessive speed or too rapid turning.
Locking: Place the vertical pump steadily in the predetermined position to ensure that its horizontal and vertical degrees meet the requirements.
Safety distance and signal communication: During the lifting process, the operator should maintain a safe distance from the lifting equipment to prevent accidental injuries. The operators should maintain good signal communication to ensure that the lifting actions are coordinated.
Weight control and emergency handling: According to the weight of the vertical pump, select appropriate lifting equipment to ensure that the equipment will not be overloaded during the lifting process. In case of emergency, stop lifting immediately and take measures to ensure the safety of personnel and equipment.
Inspection after hoisting: After hoisting is completed, check the vertical pump to ensure that it is installed in the correct position and without damage. At the same time, check the inlet and outlet pipes, motors and other systems to ensure their normal operation.
Rust prevention measures: After unpacking, vertical long-axis pumps should be rust-proof. Before installation, wipe the mating surfaces of each part clean and re-apply anti-rust oil to the mating surfaces where sealant is not used.
