1. Installation of engineering plastic self-priming pumps should be selected solid horizontal ground and keep it smooth for maintenance.
2. Try to avoid installing the machine outdoors. If installed outdoors, it should be covered with a protective cover. If the pump is equipped with an electronic controller, it must be protected.
3. Piping should be considered before the use of chemical liquids, temperature conditions and conveying head, select different pipe materials, in line with the actual requirements. For example: temperature above 60 ℃, should choose PP pipe fittings installation. Note that the self-priming pump made of PVC should be avoided by direct sunlight to prevent material embrittlement.
4. Piping should pay attention to the pipe should not be residual impurities or debris, if necessary, use water to clean the pipeline. When metal materials are used in piping, vibration-proof joints should be installed at the entrance and exit of the self-priming pump to avoid the entrance and exit flanges from being broken. The flange joints should be lined with gaskets and ensure locking to prevent air from being sucked into the self-priming pump.
5. When the engineering plastic self-priming pump conveys liquid over a certain height, a check valve should be installed at the outlet to prevent back pressure from causing damage to the pump.
6. Discharge valve should be installed between the outlet of the self-priming pump and the switching valve, and as far as possible to install a pressure gauge to monitor the pressure in the pipe.
7. The backstop valve should be installed as close as possible to the entrance and exit of the acid and alkali resistant self-priming pump, and a T-connector should be used as much as possible when installing the pressure gauge or discharge valve.
8. When piping, pay attention to the pipeline should not be twisted by force, and check whether the self-priming pump is twisted and deformed due to too much force during installation or incorrect installation action after installation.
9. After the machine is fixed, you should check whether it is firm and rotate the motor fan to make sure whether the motor can rotate freely.
10. Before connecting the power cord, make sure the power supply is compatible with the motor and connect the overcurrent protection switch.
11. Before starting the engineered plastic self-priming pump motor, fill up the liquid, check whether the inlet and outlet are open, and do not idle.
12. After the installation is completed, we should confirm whether the pipeline installation is solid, to avoid the engineering plastic self-priming pump deformation or vibration damage due to the high temperature of the liquid.
