荷兰最近研制的高载泵能适用于很脏的含泥、砂、泥炭、砾石等的污水。该泵连杆两头装有双轴承机构,为此采用密封自润滑滚珠轴承。该泵直接驱动,不需减速器。它能减小活塞的行程,并且一面增加必要的吸入和排泄量,一面减小膜片变形。其膜片是预制成型 The Netherlands recently developed high-load pump can be applied to dirty mud, sand, peat, gravel and other sewage. The pump connecting rod with double bearing body at both ends, for the use of sealed self-lubricating ball bearings. The pump is directly driven without a gear unit. It reduces the stroke of the piston and reduces the deformation of the diaphragm while increasing the amount of inhalation and drainage necessary. The diaphragm is preformed
