Automatic control lifting type shipyard water supply system

Abstract

The invention relates to an automatic control lifting type shipyard water supply system, which comprises a positioning system, a lifting system, a shipyard system, a centrifugal pump running system and an electrical automatic control system which controls the lifting system. The positioning system comprises a plurality of guide columns and a plurality of guide sliding devices, and each guide sliding device slides along corresponding guide columns. The shipyard system comprises a shipyard seat, and the shipyard seat is connected with the guide columns through the guide sliding devices. The lifting system is contacted with the guide sliding devices and tracts the guide sliding devices to slide along the guide columns and tracts the shipyard seat to lift and descend. The centrifugal pump running system is arranged on the shipyard seat. The automatic control lifting type shipyard water supply system is automatically controlled by the electrical automatic control system, can enable the centrifugal pump running system, the shipyard system and the lifting system to be controlled by the electrical automatic control to rise or descend along the guide columns along with the change of water level, and guarantees normal running of water supply of the automatic control lifting type shipyard water supply system.

Description

technical field [0001] The invention relates to a dock water supply technology, in particular to a self-controlled lifting type dock water supply system. Background technique [0002] At present, deep well submersible pumps are used to take water from water sources with a large drop. When the water level is high, the water pump is immersed in a relatively deep water level. Due to the pressure of the water, the current of the deceleration motor is overloaded, which causes the deceleration motor of the water pump to be damaged and cannot work normally. Water supply, but when the water level is low, the water supply cannot be satisfied because the liquid level is too low; the sludge pump has a small head and cannot meet the water supply needs; the centrifugal pump cannot guarantee water supply when the head is large due to cavitation at the water inlet. Therefore, the dock water supply system in the prior art cannot adapt to changes in water level, and it is difficult to ensure...

Problems solved by technology

[0002] At present, deep well submersible pumps are used to take water from water sources with a large drop. When the water level is high, the water pump is immersed in a relatively deep water level. Due to the pressure of the water, the current of the deceleration motor is overloaded, which causes the deceleration motor of the water pump to be damaged and cannot work normally. Water supply, but when the water level is low, the water supply cannot be satisfied because the liquid level is too low; the lift of the sludge pump is small, which cannot meet the needs of water supply; the centrifugal pump cannot guarantee water supply when the drop is large due to cavitation at the water inlet

Therefore, the dock water supply system in the prior art cannot adapt to water level changes, and it is difficult to ensure the normal operation of the water supply system
