Pneumatic diaphragm pump use matters needing attention QBY Pneumatic diaphragm pump precautions and application examples 1.QBY pneumatic diaphragm pump vibration is extremely mild, under normal circumstances may not be equipped with foot bolts. 2. If the compressed air enters the dirt, it will affect the normal start of the pump, it is recommended to install the pneumatic triplet. 3. In the suction easily frozen medium, should be installed at the pump inlet valve, when the stop pump, the first valve is closed, and then open the pump a few minutes, the pump body so that the media will drain the next Pump difficult. Replace the diaphragm, the pump must be within the wrist rod, lead sleeve clean, and do not damage the white PTFE seals, according to the original installed, you can use. Pneumatic diaphragm pump application examples 1. Tank bottom, despite pad pumping, there is no guarantee that the net oil pumping, the surface always left at least 3-5mm thick layer. To 5000m3 tank, for example, each about 1-1.5t oil loss. For tanks with low dewatering tanks, the remaining oil and water can be discharged to the oily wastewater treatment plant for recovery, but the volatile oil is mostly evaporated during transport and pollutes the environment. 2. Temporary inverted cans, loading trucks and oil samples, oil refining production scheduling process, the oil often to be temporarily inverted cans, loading and oil tank oil sampling inspection. Or to not contaminate the normal pipeline, the diaphragm pump temporary pipeline connection can quickly and easily accomplish this task. 3. Tanker tank bottom oil recovery A 3000t tanker with a fixed screw pump unloading, warehouse at least 50t residual oil between the partitions, if the displacement of a larger partition pump, you can receive good results. 4. Gas, hydrogen sulfide residue transport Refinery flames at the bottom of the gas residue and sulfur water, you need to focus on emissions and treatment, or will form acidic corrosion equipment. 5. Ceramics industry: The pump suction glaze, and can be used to send pressure to the filter press. 6. Drainage wells, undergrowth to exclude waterlogging, sewage pipe in the water wells, valves and undercut maintenance, the need to rule out waterlogging and sewage oil. Although submersible pump pumping exhausted water, but often these places are far from the power, it is inconvenient. The use of diaphragm pumps can be compressed gas cylinders as power recovery of oil, drain water collapse. 7. Sewage treatment plant and sludge pool cleaning Sewage pond sewage treatment plant, often accumulate a large amount of sludge and silt, you need to clean, the use of diaphragm pump suction flexible, convenient labor-saving, labor-saving and time-saving. 8. Liquefied gas pump room and laboratory row of water, as these places are low, but also a fire area, the use of diaphragm pump row of water is more safe than pumping water pumping, steam pumping efficiency many times higher. 9. In addition, the pneumatic diaphragm pump used in refined naphthenic transfer, loading sodium sulfite liquid transport, benzene loading and unloading of raw materials, etc. has its own advantages.
