MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准，过流部件采用聚苯硫醚，不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等)，其性能接近于聚四氟乙烯的化学性能，在100℃以下能耐大多数有机溶剂，特别能耐汽油和甲醇的混和液，是酸碱工业中的理想用泵。

In this paper, we put forward an idea that the concrete pump car is robotized. For some problems about booms'robotization of concrete pump car, a lot of studies are thoroughly accomplished, by means of intelligent optimization method and finite element method of model design method, robotic kinematics and dynamics theory, computer graphics, computer simulation, mechanical control technology, hydraulic control technology, and so on. This idea establishes a new development way for research, design improvement and updating of the concrete pump car.
