SZ type glass fiber reinforced plastic self-priming pump

SZ type glass fiber reinforced plastic self-priming pump

Overview of SZ type glass fiber reinforced plastic self-priming pump:

   SZ-type FRP self-priming pump, the flow-through parts in contact with the medium are all made of modified phenolic glass fiber material and molded at high temperature. The product has excellent properties such as light weight, high strength, no deformation, temperature resistance, corrosion resistance, convenient maintenance and repair. The shaft seal adopts WB2 type external check valve and return hole. Before starting work, it is only necessary to ensure that a certain amount of liquid is stored in the pump body, and the air in the pipe can be drained first and then the liquid can be discharged. There is no need to install a bottom valve, and the liquid in the barrel can be pumped, thus simplifying the pipeline system and improving the working conditions. Limei brand SZ FRP corrosion-resistant self-priming pump is widely used in petrochemical, smelting, dye, printing and dyeing, pesticide, pharmaceutical, rare earth, fertilizer and other industries. Ideal equipment for corrosive media such as non-oxidizing acids (hydrochloric acid, dilute sulfuric acid, formic acid, acetic acid, butyric acid).


2. The main purpose of SZ FRP self-priming pump:

This pump is widely used in chemical, petrochemical, smelting, dyestuff, pesticide, pharmaceutical, rare earth, fertilizer and other industries. The most ideal equipment for corrosive media such as hydrochloric acid, dilute sulfuric acid, formic acid, acetic acid, butyric acid.

3. When reassembling the SZ-type FRP self-priming pump after repairing and replacing wearing parts.
  1) First, install the front and rear bearings and oil seals in the front and rear covers separately, and install the front cover with bearings on the SZ-type FRP self-priming pump shaft, and then install the pump shaft with the front bearing cover on the frame. superior.
  2) Put the bearing press sleeve on the pump shaft, and then install the rear cover with the bearing on the pump shaft and the frame.
  3) Set up the pressure ring, install the coupling and tighten the nut.
  4) Put the tissue sealing ring on the pump shaft.
  5), install the static ring in the SZ type FRP self-priming pump body, and tighten the compression screw sleeve.
  6) Put the SZ-type FRP self-priming pump body with static ring on the frame, and debug the cooperation of the dynamic ring of the mechanical seal (usually 3-3.5mm tight), and then take off the pump body first.
  7) Fasten and fix the mechanical seal dynamic ring on the pump shaft, then install the pump body on the frame, and turn the mechanical seal dynamic ring on the coupling by hand to see if it fits together.
  8) Install the impeller on the pump shaft, and use a tetrafluoro gasket to adjust the gap between the impeller and the pump (usually tight between 2-2.5mm) and pad the anti-corrosion gasket, then tighten the impeller and cap, and finally pad the pump. Shell gasket, install the pump cover, and tighten the anti-corrosion nut.
  9) Install the assembled pump bucket on the bottom plate, and adjust the gap of the coupling and the axis of the motor to be straight.
8. Pay attention to the normal maintenance of the SZ-type FRP self-priming pump. Always check whether the pump is running smoothly and whether there is abnormal vibration. Pay attention to replacing the elastic block, make up for the lubricating oil of the bearing according to the oil mark, and replace the lubricating oil in the frame regularly.
 

This pump is widely used in chemical, petrochemical, smelting, dyestuff, pesticide, pharmaceutical, rare earth, fertilizer and other industries. The most ideal equipment for corrosive media such as hydrochloric acid, dilute sulfuric acid, formic acid, acetic acid, butyric acid.
