Why did it leak? The quality is too bad.. When a leak occurs, the solution is to replace a new mechanical seal. It should also be noted that the pump is forbidden to work without liquid. The medium was also a clean liquid, but there was water leakage after a short period of operation. At this time, users will reflect that this pump is still new after we bought it, and it hasn't been used yet.Then close the inlet valve.. According to the instructions, the leakage degree of the sealed equipment is less than three drops per minute under normal conditions, and the temperature of the bearing part should be less than 70 degrees Celsius. The correct operation steps of the horizontal centrifugal pump are as follows: Regarding the starting and 3.5" Submersible Borehole Pumps running of the manual adjustment impeller, it should be able to rotate smoothly under normal conditions. After the normal start, to determine the correct running track, from the direction of the impeller, the normal rotation is clockwise. If an abnormal state or sound occurs during work, stop testing immediately. Regarding shutdown: first close the valve at the outlet when you stop workingIts 3.5" Submersible Borehole Pumps technology makes it more stable at work, and its noise is limited to the extent that it will not affect the surroundings; its integrated structure makes the equipment have a better balance and compatibility, and the use time The period is longer.. The details are as follows: The overall structure of the equipment has a smooth appearance among many centrifugal pumps of the same type. The horizontal design makes its overall appearance more natural; at the same time, its horizontal design can save space and costs at the construction site, and directly outdoor Place to run.
