Methods to improve water absorption reliability of self-filling dosing pump

[Asia Pump Network News] often used self-dosing dosing pump suction mode is to make the pump shaft elevation below the working level of the pool. This method is often used in basement buildings, layout, the pump room is set in the basement, the pool set in the basement next to the pump room or outdoor underground. This way of absorbing water, the working level of the water tank is higher than the pump shaft elevation, so that the water suction pipe is always filled with water, which can ensure the pump to start automatically and quickly. How to improve its reliability, following Xiaobian to introduce to improve the self-filling dosing pump water absorption method of reliability! When dosing dosing pump from the pool water, if the use of self-irrigation water absorption, the suction pipe can be filled with water, dosing dosing pump start, eliminating the need for irrigation exhaust time, can be quickly put into operation, improved Dosing metering pump to start the automation and reliability. Often used in self-irrigation water absorption is the dosing pump axis elevation lower than the pool water level. This method is commonly used in basement buildings, layout, the dosing metering pump room set in the basement, the pool set in the basement metering dosing pump room next to or outside the ground. This way of absorbing water, working pool water level higher than the dosing pump axis elevation, the water pipe has been filled with water, to ensure that dosing pumps automatically, quickly start. For buildings that do not have a basement, there are difficulties with the self-filling suction method described above. Because of this construction, dosing metering pump room is generally arranged on the ground floor, if the bottom of the dosing metering pump room next to the pool, especially the relatively large volume of fire water tank, it will take up a lot of ground floor area, the general construction unit Will not agree. In this case, the pool is usually set outside the building and buried under the ground. This will result in the working pool water level is lower than the dosing pump axis elevation dosing dosing pump can not be achieved from the filling water absorption, this time, you can use the following ways to solve this problem. The first way is to install a suction end valve at the end of the suction pipe of the dosing metering pump. Suction valve at the end of the valve is actually a check valve, which ensures that water can only enter the suction pipe from the pool and can not reverse, so if the suction pipe filled with water, although the dosing pump axis elevation above the working level of the pool, but due to Suction valve at the end of the role of the water pipe will not flow into the pool, the suction pipe has been filled with water to ensure that dosing metering pump can automatically and quickly start. The reliability of this way of absorbing water is affected by the quality of the suction bottom valve. For example, the water in the suction pipe slowly flows into the pool due to lax shut-off and water leakage, and there is no water in the suction pipe for a long time. As a result, the dosing pump Still need to start when the artificial irrigation. The following way to absorb water to make up for this shortcoming. The second way is to use other water sources. On the basis of the first water absorption method, a pipe is installed in front of the check valve of the dosing pump outlet pipe, and this pipe is connected to an outdoor municipal water supply pipe or other external water source to absorb water from the dosing metering pump Tube water supply, supplement the valve leaked water, so that the suction pipe filled with water. The reliability of this way of absorbing water is affected by the outdoor water source. Under the condition of long-term water stoppage in the outdoor water source, the water in the water-absorbing pipe may be leaked. Therefore, the dosing metering pump needs to be manually irrigated when it starts up. The above is to improve the self-filling dosing pump water absorption method of reliability, I hope you can learn to apply, in the future life, if you have encountered similar problems, they have to know how to deal with flexibility.
