4.14 The base and shaft parts should be sealed. 4.15 The rated life of the upper body should not exceed 25 hours. 4.16 If the pressure-bearing parts are prone to corrosion, their strength should have an appropriate corrosion resistance. 4.17 The pressure-bearing parts such as the limiter parts shall have sufficient characteristics and shall not be subjected to the temperature, pressure and external forces and external torques on the conveying medium, which may cause the leakage of the conveying medium. 4.1B The exposed moving parts of the pump shall be inspected and the appropriate materials shall be used for corrosion control or other measures shall be taken. 4.19 The assembly torque of the connecting rod bolts, the metal body screws and the nut shall be specified. 4.20 The couplings and the transmission rubber shall be equipped with protective devices around other moving parts that may cause injury to the human body. 4.21 When the system is used in a flammable environment, the explosion-proof type, type, level and group of the motor and electrical equipment can refer to the provisions in the appendix of 3535.1-83. The protection of exposed parts shall be non-sparking: the transmission belt shall be anti-static. If the belt is fully enclosed and forced ventilated, a single-strand transmission belt is allowed. 4.22 The installation and maintenance of the pump shall be carried out by the professional contractor. 4.23 The replacement of the pump parts shall be in accordance with the provisions of Table 3. s
