The widespread use of pumps (pumps), such as centrifugal pumps, axial flow pumps, submersible pumps, mixed flow pumps, there is the use of power machinery and pump power to match the unreasonable, burning machine, energy consumption, high repair costs and other issues. Resulting in the waste of manpower, material resources and financial resources, increasing the economic burden on users. To this end, everyone in the use of pumps, the need to pay attention to the following issues. First, the matching power and pump (pump) rated power to match. How many kilowatts a typical pump requires, and there are clear rules on the pump nameplate. If you do not complete, the power of power is too large, it will result in "big car", wasting power and increase costs; on the contrary, there will be a "small horse drawn cart", water flow is insufficient or overload work, damage to the parts , Unable to work, waste of investment. Second, the new machine starts pumping, wipe the pump shaft and other parts of the protective oil. Carefully check the rotation of the impeller is normal, the pump shaft rotation is flexible, bearing clearance is appropriate to see if the pump body joint gasket is damaged, the connection is solid parts, inlet hose leaks, leaks and so on. If there is a problem, it should be promptly repaired. Third, the installation of pumps and power machinery to be solid. To be particularly parallel to the pump shaft and power shaft; install the belt, you should pay attention to loose belt to be on, in order to facilitate increased transmission efficiency. Fourth, with the electric motor driven pump pumping, two pumps are prohibited at the same time start the homework to prevent the entire line current is too large, and burn the motor, causing undue economic losses. Fifth, we must promptly check the pump inlet valve, weeds are blocked. Pay attention to see whether the flow head meet the performance requirements. Once found problems, to be immediately ruled out to ensure normal operation. Six, stop pump pumping, you must first close the pressure valve, and then stop working, the belt removed. In a longer period of downtime, we should carefully clean the whole machine, the water pump completely put away. On the machine easy to corrosion of parts and spare parts, to be coated with protective oil to prevent the pump rust.
