Pump installation and routine maintenance procedures
First, the installation and commissioning of the pump 1, the installation of the pump 1.1 Before installing the pump should be carefully checked whether there is any impact on the pump runner pump hard material (such as stones, iron particles, etc.), so as not to damage the internal parts. In the entire installation process, should be gently. So as not to damage the pump seal and bearings. 1.2 Pump should be installed in the ground strong and solid place, there should be sufficient room left for easy inspection, maintenance and repair. 1.3 Under the pump base should be to maintain the level of the foundation, the corners of the base pad recommended rubber pad or ground anchor screws to ensure smooth operation of the pump. 1.4 pipe weight when installed should not be added to the pump, should have their own support, so as not to distort the operation of performance and life expectancy. 1.5 pump and system connections Pipeline should be sealed and reliable, small pumps can be used to connect the metal pipe Gasket with oil and rubber, and the pipeline required less and less elbows. Welding pipe should be removed when the slag in the pipe, welding slag is prohibited inside the pump impeller or mechanical seal damage. 1.6 according to the motor signs connected to the power supply, and ground wire and install the appropriate specifications of the fuse and thermal relay. 1.7 For the pump with cooling water, turn on the cooling water as required, otherwise the machine seal and the seal ring will be damaged. 1.8 If the pump port to install solenoid valve, the valve and the pump should be at the same time action. 1.9 When the pump exhaust gas affect the working environment, can be installed in the exhaust port of the pipeline to remove or install the filter. 1.11 pump suction stroke occasions, should be equipped with a foot valve, and the inlet pipe should not have too many corners, at the same time not have leakage, leakage phenomenon. 1.12 After the installation is completed, the pump shaft is to be struck. The impeller should be rubbed or stuck. Otherwise, the pump should be disassembled to check the cause. 2, the pump debugging 2.1 hands before dialing motor fan blade, the impeller should be no card grinding phenomenon, flexible rotation. 2.2 Open the inlet valve, open the exhaust valve to fill the entire pump with liquid, and then close the exhaust valve. 2.3 Check the motor to determine the steering is correct. 2.4 connected to the power, when the pump reaches the normal speed, then gradually open the valve on the discharge pipe and adjust to the required conditions. 2.5 observe the instrument readings, check the seal leakage, the normal mechanical seal leakage, <3 drops / min, check the motor, the bearing temperature ≤ 70 degrees C, if abnormal, should be promptly addressed. 2.6 gradually close the discharge pipe valve, cut off the power. 2.7 Close the inlet valve. 2.8 If the ambient temperature is below 0 degrees C, the pump liquid should be depleted to avoid cracking. 2.9 If disabled for a long time, the pump should be disassembled and cleaned, packed and stored. Second, the pump maintenance 1, check the pump power cord is aging, broken skin, the power cord copper leakage. If the power cord is on shore, you can wrap it with electric tape. If it is in the water must be replaced by the power cord. 2, often check the pump impeller for dirt, foreign objects, such as blocking the water outlet impeller or the outlet; check the sound of the pump is running well, if there is noise, pump damage or pumps have debris, the need for maintenance or replacement parts. 3, regular checks whether the pump running leakage, if leakage, please consult the pump manufacturer or request to send someone to repair. 4, if the working environment temperature is below 0 ℃, after shutting down to remove the pump water to avoid freezing cracked pump 5, if the pump aside for a long time do not, it should be inside the stagnant water and then add anti-rust agent.
