Glass fibre reinforced plastic pump, the wetted parts are made of polyvinyl butyral, modified phenolic glass fiber material formed by high temperature molded, with good corrosion resistance, high temperature resistance, light weight, high strength, deformation and so on.
Even good material of glass fibre reinforced plastic pump, if they are used improperly, it will bring damage to the pump.
Here are several glass fibre reinforced plastic pump maintenance and repair methods for daily use:
1. inspect the glass fibre reinforced plastic pump piping and binding sites for any loosening. Turn the glass fibre reinforced plastic pump with your hand, look at glass fibre reinforced plastic pump are flexible.
2. Add bearing lubrication oil to bearings inside, observe oil level should be at the centre line of oil, lubricant should be timely replacement or supplement.
3. unscrew the diversion of glass fibre reinforced plastic pump body screw plug, pouring water (or pulp).
4. close the valve outlet pipe road and import and export pressure gauge vacuum gauge.
5. move the motor, try shift motor is correct.
6. start the motor, when after the normal operation of the glass fibre reinforced plastic pump, open export vacuum pumps depending on the pressure gauge and imports showing adequate pressure, gradually open the valve and check the motor load.
7. keep control of glass fibre reinforced plastic pump flow and lift within the range indicated on the poster, to ensure the glass fibre reinforced plastic pump running at the highest efficiency, in order to get the maximum energy savings.
FRP pump installation requirements
1, FRP pump pump must be mounted vertically on top of the liquid pools or tanks on the mounting bracket.
2, FRP pump pool pump suction distance should be greater than 200 mm at the bottom.
3, FRP pump pump exit pipe must be designed with ribs that will not allow its weight falls directly on the pump body.
Second, FRP pump disassembly sequences
1, FRP pump turns off valve in pressure pipe, remove the upper flange of spit tube bolt or joined to take over. Remove piping length prevented pump lifting shall prevail.
2, FRP pump loosen the bolt of the motor frame and the motor, lift motor.
3, remove the pump body bracket bolt, spin off the impeller.
4, remove the middle bracket, pull down the shaft coupling.
5, remove the bearing body top and bottom bearing cover, you can check the bearing conditions.
C, FRP pump starting, stopping and operating requirements
1, FRP pump motor is not installed in the former should be plugged check the direction of rotation must be consistent with the provisions of the pump rotation direction.
2, FRP pump equipped with motor, disc couplings, check that the motor and pump shaft is concentric, rotating weight unevenness, normal and functioning again.
3, FRP pump shut down the export pipeline valves and pressure gauge.
4, FRP pump starter motor, indicated by a pressure gauge open the outlet valve to the desired position.
5, FRP pump normal parking, you should close the outlet valve, and then stop the motor, close the pressure gauge.
6, FRP pump bearing Chamber shall ensure that a sufficient number of grease, bearing temperature rise shall not exceed 70 degrees centigrade.
