Diaphragm pump is divided into pneumatic diaphragm pump and electric diaphragm pump
Do you need to pump before starting the diaphragm pump? No need, the diaphragm pump has a theoretical suction range of five meters, in the proper installation and correct layout of the pipeline can be used, do not need to pump in advance like other pump products, but if the suction inlet is too long due to special conditions, due to the increase of resistance will cause insufficient suction, this still need to pump, details can see saiken pump industry brought by the following content.
On whether the diaphragm pump needs to start before the pump, as long as the medium itself does not exist too high viscosity, and the pipeline layout is too long, it is not necessary to pump. If the pump body installation and pipeline layout is correct in the case of not normal water absorption, consider the following problems.
1. The transport medium exceeds the standard: Diaphragm pump has a comparable screw pump medium adaptability, can easily handle all kinds of glue liquid and liquid containing particulate matter, but the medium viscosity and particle diameter of the requirements, the specific processing capacity is affected by the size of the diameter, different diameter of the diaphragm pump has different adaptability to the medium, if the medium viscosity or solid content exceeds the transportation standard, Will lead to the internal flow channel gradually narrowed until blocked, it is recommended to replace higher standard pump type according to the actual conditions;
2, the air source is not pure: the power source of pneumatic diaphragm pump is compressed air, in some high humidity environment, water into the compressed air will have a direct impact on the performance, it is recommended to use industrial dryer to relieve humidity, can also be installed in the pump inlet filter;
3, component wear: diaphragm pump internal components less, multiple parts can work for a long time, but the diaphragm belongs to consumables, need to be replaced regularly, usually can be used for half a year to a year, according to the frequency of use, if the diaphragm pump in the suction material at the same time to accompany a certain liquid leakage, then consider the diaphragm damage. In addition, you can also check the connection bolts, air distribution valve, brake piston rod, guide valve, shaft sleeve, check valve and other components inside the diaphragm pump, and replace the parts that have been worn to failure.
The above content describes whether the diaphragm pump needs to start before the irrigation pump, visible under most conditions are not needed, if there is no normal suction, can also be handled according to the cause of the fault, if you need professional technical support, you can directly contact saiken pump industry.
