Fluorine plastic self - priming magnetic pump installation and maintenance

Fluorine plastic self-priming magnetic pump in recent years, pump research and development of a major breakthrough pump straight motor structure, the main components of the steel liner F46, pump body strength, resistant to all the strong acid and strong Alkali corrosion. It is supported by the middle bracket and has the advantages of compact structure and convenient disassembly and maintenance. The inner and outer magnets are made of high-performance magnetic material "NdFeB", and the insulating sleeve is made of imported non-metallic materials, completely eliminating the magnetic eddy current loss of the general magnetic pump, , The density is greater than 1.84t / m3 strong corrosive medium. The following let Xiaobian to introduce the fluorine plastic self-priming magnetic pump installation and maintenance of it. Fluorine plastic self-priming magnetic pump installation and maintenance 1, according to the basic size of the concrete foundation, at the same time to the good buried anchor bolts. The unit on the basis of the pump to find the level, tighten the anchor bolts. Pump should be as close to the pool as possible. 2, the pump inlet pipe diameter shall not exceed the required requirements, and the total length of the inlet pipe is not more than 5m, in the case to meet the requirements, the shorter the better. Into the bottom of the liquid pipe must be installed to prevent excessive particles or debris into the pump body damage to the impeller or affect the pump, the filter area should be greater than 3-4 times the cross-sectional area of ​​the pipeline. 3, the pump out of the pipeline must be equipped with a valve to regulate the flow, so that the pump work under the provisions of the flow to prevent over-pump to prevent work. The diameter of the liquid outlet shall not be less than the specified requirement, and the larger the liquid outlet diameter, the better the liquid outlet if possible. The total length of the outlet tube must be more than 1.5 times the total length of the inlet tube, making it longer if possible. 4, the weight of the inlet pipe and the outlet pipe can not be supported on the import and export flanges of the pump, and should be fixed on the respective brackets. In and out of liquid pipe connections must be close to each part, airtight, otherwise it will affect the self-priming function and the normal operation of the pump. (2) Usage and maintenance instructions: 1, self-priming magnetic pump is strictly prohibited transport containing solid particles or easy to crystallize the media, does not allow the discharge port in the case of continuous operation, the need to maintain the minimum flow. 2, the installation of pipelines, the first access pipe, fill the liquid and then take the outlet pipe. 3, after installation, connect the power, check with jog mode whether the rotation of the pump is flexible, check whether the motor steering and steering signs are the same. 4, the outlet valve to open about one-third, you can start the self-priming pump (that is, open the valve to start), and then slowly adjust the outlet valve so that the pump can not work properly. 5, infusion, the flow, lift and self-absorption height must be controlled within the specified range, can not differ too much, otherwise it will cause suction phenomenon, so that the pump can not work properly. 6, self-priming pump at work, not allowed to produce suction phenomenon, once produce suction, you must re-drain irrigation fluid to self-absorption. Therefore, the user must have a device for controlling the lowest level or hand-held person to prevent the medium inside the basin from being vacuumed. 7, self-priming pump can not transport a large number of bubbles of medium, can not transport gas-liquid mixture. 8, in the transport medium containing easy to crystallize, if there is a period of time to stop the pump, you must flush the pump chamber, no residual crystallization medium to prevent damage after crystallization restart pump; re-use, Suck. 9, the general transmission of non-crystalline medium, if the long time to stop using the pump, check before starting the pump liquid is sufficient, please make up to self-absorption. 10, When the pump is placed in the environment below the liquid level or use instead of pipeline pump, can not be equipped with air valve and buffer valve, in this case, please remove the air valve and buffer valve can be. 11, the pump outlet pipe shall not be installed check valve, if any, must be set at the bottom of the check valve vent. 12, self-priming height can be an easy formula to calculate: water self-priming 3m / medium density = actual self-priming height.
