Preparation before installation:
1, the installation of pipe weight should not be in the pump, or easy to damage the pump;
2, the pump and motor is the overall structure, the factory has been calibrated by the manufacturers, so no need to adjust the installation, the installation is very convenient;
3, the installation must be tightened anchor bolts, and every interval of time to check the pump to prevent the loosening, so as to avoid violent vibration of the pump starts and affect the performance of the pump;
4, the pump should be carefully checked before the pump runner affect the operation of the hard material (such as stones, iron, etc.) to avoid damage to the pump running over-flow parts;
5, in order to facilitate the maintenance and use of safety, in the pump outlet pipe installed on a control valve and the pump near the entrance to install a pressure gauge, high-lift pump, in order to prevent water hammer, but also in the export gate valve installed A check valve to cope with power outage and other power loss accident, so as to ensure that the pump in the best conditions to run and increase the service life of the pump;
6, for the liquid below the pump inlet and no vacuum pump conditions, according to the installation diagram according to the installation method, the first pump inlet after filling up to run at the same time import pipeline should not have too many corners, may not have Leakage, leakage phenomenon, so as not to affect the pump suction performance;
7, in order not to impurity into the pump and plug the flow channel affect performance, should be installed in front of the pump inlet filter;
8, install the pipeline before turning the pump rotor parts, should be no friction sound or stuck phenomenon, otherwise the pump should be opened to examine the reasons.
Before starting:
1, pull the coupling by hand, the impeller should be no card grinding phenomenon, flexible rotation;
2, open the inlet valve, open the exhaust valve to fill the entire pump chamber liquid, and then close the exhaust nozzle;
3, such as the delivery of hot liquid, the pre-start should be warm, the heating rate of 50 ℃ / h, the pump is preheated with the circulating fluid to achieve continuous, so that all kinds of various parts of uniform heating;
4, should first hand pump a few laps to make lubricating water into the mechanical seal end;
5, Jog motor, to determine whether the steering is correct.
Start and run:
1, fully open the inlet valve, close the spit line valve;
2, connected to power, when the pump reaches the normal speed, and then gradually open the outlet pipe on the valve, and adjust to the required conditions;
3, observe the instrument readings, check the shaft seal leakage, the normal mechanical seal leakage of 3 drops / min, check the motor, bearing temperature ≤ 75 ℃, if abnormal circumstances, should be promptly dealt with.
parking:
1, gradually close the spit out the pipeline valve, cut off the power;
2, close the import valve;
3, if the ambient temperature is below 0 ℃, the liquid should be exhausted pump, so as not to freeze cracking pump;
4, such as long-term disabled, the pump should be demolished cleaning, packaging custody.
