The pump Can be used on board a ship to pump and deliver bottom ballast water or sea water for cooling,fire,sanitary as well.The temperatures of the media transferred should not exceed 70℃.
1.3泵的性能參數(shù)應(yīng)符合表1、表2的規(guī)定。
The characteristics parameters of the pump should satisfy those 0ne given in Table 1 and Table 2.
The pump,with a horizontal suspension arm,is a single-stage,one-way suction.axial entry,and self-sucking one.nle structure of the pump body IS of mixed flow type.The pump body is composed of a suction bend,a snarl casing,an air-water separating cavity and a water storage cbambeL At the bottom ofthe snail casing there is all axial return flow opening.
Inside the nerar pump cover there is a sealed cavity,in which fiUer seal or axial seal is fitted.The weight ofthe pump shaft and the vane whirl,together with the radial force created by the vane whirl,is supported by the two centripetal bearings in the bracket.To convey torque,an elastic coupling joint is installed to connect the pump and themotor.
Two stands are cast to the lower part of the pump.Both the pump and the motor ale fixed to the base.Our customers who want pumps driven by belt pulley are suggested to specify it clearly in the contract SO as to avoid wrong shipment.The other model of pumps with a base will be delivered otherwise.
