Pipeline pump installation can not be ignored some of the details of attention First, the choice of suitable for the head of the pipe pump Pipeline lift is generally considered small, the power consumption is small. However, in fact, the power consumption is proportional to the pump flow pipeline, lift small, the flow will increase, the power consumption will also increase. Therefore, when high lift is used for low lift pumping, the motor will generate heat due to overload and even burn the motor. Note point two, the depth of the pipeline pump inlet pipe pump inlet water too deep can easily lead to the sink pool of debris caused by the blockage, inlet and bottom of the pool distance should be greater than 1.5 times the diameter of the inlet; if the inlet into the water too Shallow, will produce vortex, affecting the water, suitable depth of 600 ~ 1000mm. Attention point three, the pipeline pump as little as possible to connect the elbow bend will lead to increased water flow resistance, and if the pipeline pump inlet directly linked with the elbow, it will cause the water flow into the impeller when the water flow is not uniform. If the elbow should be installed in the vertical direction, installed in the horizontal direction will gather air, resulting in reduced water. Attention point 4, the horizontal section of the pipeline pump inlet pipe to the water source direction to a slight tilt The horizontal section of the water inlet pipe if the level set, or tilt up, will cause the water pipe to reduce the degree of vacuum gathered air, so that the head lower , The amount of water will be reduced. Attention to point five, when installing the bottom valve, the inlet pipe should be as vertical as possible to install the bottom valve inlet pipe should be vertical or water pipe axis and the horizontal angle of 60 degrees or more. Reminder: According to the State Council issued Decree 158 "Urban Water Supply Management Regulations": "Prohibit the direct installation of pumping water in urban public water supply pipelines." Taking into account the reservoir water pollution easily deteriorated, and the water into the pool wasted water pressure is a waste of energy, and the pool occupied a larger area and other factors. From the beginning of this century, the Ministry of Construction, Ministry of Science and give permission to promote booster (laminated) water supply device below. However, in order to avoid pollution and affect the water users around, not directly from the public pipe network pressurized pumping. Users should pay attention to the availability of health permits when using the device.
