IH chemical pump installation and maintenance disassembly and assembly disassembly: As a result of longer coupling IH65-50-125 Naifushibeng, when disassembling the pump, without dismantling the inlet and outlet piping, pump and motor, just remove the extension linking Couplings intermediate coupling to split out the rotor parts, repair and maintenance. 1. Remove the vent tube on the pump discharge pipe plug on the block body and suspension, put in the net and the suspension liquid pump body oil. (Note: If there is another additional piping to the pump should be removed). 2, open the pump and intermediate coupling bracket and the middle frame, suspension components and pump cover all the rotor components together to exit from the pump body. 3. Remove IH50-32-160 stainless steel pumps, impeller nut, remove the wheel and the key. 4, together with the pump cover sleeve, mechanical seal cover and wheat mechanical seals and other components together to exit from the shaft. Be careful not to cover the sleeve relative to the pump, such as sliding, and then remove the cover mechanical seals, mechanical seals will be removed along with the sleeve together IH50-32-250 stainless steel pumps, then the sleeve and mechanical seal apart. If sealed with packing, you can simply remove the cover from the pump shaft sleeve, and then sequentially remove the packing gland, packing and packing ring. If the seal with the special structure of stainless steel pumps, should pay attention to the different disassembly methods. 5. Remove the middle bracket and suspension bracket. 6. Remove the pump coupling and key. 7. Remove the front suspension and both ends of the dust disk bearing, back cover, and then remove it from the shaft together with the bearing along with the suspension body. 8. Remove the bearing from the shaft. Assembly and disassembly procedures were contrary. Start-up, operation and maintenance of mechanical seals to stop five chemical process pump mechanical seal for maintenance, you should use special tools to properly remove the mechanical seal dynamic and static ring, and check the face wear, the closure of all installed pump rotor, regardless of power size, should be done moving or static balance test. To ensure that the seal does not leak, fitter platform available on the movement side pressed down Sheung Shui to do a leak test, if the static water does not leak, indicating that the surface roughness and flatness of the sealing surface are in line with requirements. When installing the end face of the vertical deviation of not more than 0.015mm. Radial or part of the shaft sleeve runout values. After installing the axial runout its axis is not more than 0.45mm. Emphasis should be noted that according to the requirements of the mechanical seal installed, be sure to jigger, and check the cooling water part is reliable, prevent the rotation of the end face seal leakage or damage to the machine. Chemical pump mechanical seal used mostly for single-stage, two-stage, tandem seal arrangement, but no matter what kind of sealing arrangements are not leaks.
