Abstract
The present invention relates to a dredge pump belonging to the sewage disposal technical field, particularly to a vertical disintegrated self-suction dredge pump which is characterized in that an impeller is designed into a wide-open structure, and therefore, the carrying capacity of the pump is increased and the energy efficiency is increased. The wide-open impeller and a guide blade are combined, which effectively balances the axial force and the radial force. A cutting device is arranged in a pump body, which can effectively pulverize blocky grains and long fibre substances. A blowdown valve is arranged on the outlet of the pump, and therefore, the steam generated when the steam and the liquid are separated can be exhausted after the blowdown valve is opened. An electromagnetic valve is arranged on a suction mouth of the pump body. When the pump stops working, the electromagnetic valve is opened, and then the air enters the suction mouth of the pump body, which can prevent the water in the pump body from being exhausted due to the siphon function. The present invention has the advantages of reasonable structure, small size and reliable work, combines the pulverizing function, the steam exhaust function, the siphon preventing function and the pumping function into integration and can be widely applied to sewage conveyance containing friable solid particles and long fibre and be used on board.
Description
Technical field
