[Asia Pump Network hearing] pump installation is reasonable, the normal operation of the pump and the life has a very important impact, so the installation and calibration must be carefully carried out. Now to introduce IHF-lined fluorine plastic centrifugal pump installation, operation precautions and maintenance methods. IHF-lined fluorine plastic centrifugal pump I. IHF-lined fluorine plastic centrifugal pump installation considerations 1, control the installation of the size of the embedded good foundation bolts, do a good job of concrete foundation. 2, to be based on the foundation cement solidification, the pump installed on the basis of the level of the pump and motor shaft level check, if not level, the use of horns until the level of leveling, tighten the bottom nut after tightening. 3, check the rotating parts of the pump is stuck rub phenomenon should be strictly check the coaxiality of the pump shaft and the motor can be adjusted to make it concentric sheet, the last hand to rotate the coupling, the phenomenon of easy and uniform rotation without rubbing Normal. 4, pump suction and discharge pipe should have their own bracket, does not allow the weight of the pipe directly to withstand the pump, so as to avoid the pump crushed. 5, the installation of the pump above the liquid level (within the pump suction allowable range), the end of the suction pipe should be installed on the end of the valve, and in the discharge pipe set up irrigation screw or valve for pump start Before filling the pump; pump installation location below the liquid level, the valve should be installed in the suction pipe and filter control device to prevent debris sucked into the pump, the filter area should be greater than 3-4 times the pipe area. 6, lift the pump at the outlet flow control valve on the outer pipe should also be installed check valve to prevent water hammer damage suddenly shut down. 7, must ensure that the pump installation height in line with the pump NPSH, and consider the pipeline loss and medium temperature. Second, IHF-lined fluorine plastic centrifugal pump operation 1. Pump before the pump should be filled with full plus liquid transport, no liquid start. 2. Close the outlet valve, turn on the power immediately after checking the steering pump must be consistent with the pump steering arrow, reverse operation is strictly prohibited, 3. After the pump reaches the normal speed of rotation, and then gradually open the outlet valve and adjust to the required work Conditions put into operation. In the discharge valve on the pipeline closed, the pump can not work continuously for more than 3 minutes. 4. Shutdown should be the first outlet of the valve closed, and then cut off the power. Third, IHF-lined fluorine plastic centrifugal pump maintenance 1. Regularly check the pump and motor, replace the vulnerable parts. 2. Always pay attention to the bearing box filled with high-quality calcium-based grease to protect the bearings under a good lubrication state. 3. Long-term downtime when not in use, in addition to the pump of corrosive liquid into the net, but should pay attention to the various components and pump flow channel clean, and cut off the power. 4. No-load pump is strictly prohibited. 5. If the media contains solid particles, the filter should be added at the pump inlet.
