Installation methods and operating procedures for pneumatic diaphragm pumps

If the installation details of pneumatic diaphragm pumps are ignored, long-term careful planning, research, and selection may still lead to poor pumping performance and affect the pump's service life. Pneumatic diaphragm pumps are a new type of conveying machinery that uses compressed air as the power source. For various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids, they can be pumped and absorbed completely. The diameter of the suction pipe of the pneumatic diaphragm pump should not be smaller than the diameter of the pump inlet end. For example, when transporting high viscosity fluids, the diameter of the suction pipe should be greater than the diameter of the pump inlet. The suction piping at the inlet end must be durable and free from wrinkles in order to generate a high vacuum state. The diameter of the outlet piping should be at least equal to the outlet diameter, or slightly larger to reduce friction losses. All piping and joints must be sealed without leakage, otherwise it will reduce the self priming capacity of the pump. Pneumatic diaphragm pump is a commonly used machinery in the chemical industry. After purchasing this pump, if it is not installed by specialized technical personnel, it is likely to delay production. In the following article, I will briefly introduce the installation steps and operating procedures of pneumatic diaphragm pump.
Installation method of pneumatic diaphragm pump
1. Location: Noise, safety, and other logical factors usually have requirements for the location where the equipment should be installed. Parallel installation with conflicting requirements may cause blockage in the usage area and affect the installation of other pumps.
2. Usage: Firstly, the position of the pneumatic diaphragm pump must be easy to use, which will facilitate daily inspection and debugging by maintenance personnel.
3. Air supply: Each pneumatic diaphragm pump should have a ventilation pipe that can provide enough air to achieve the ideal pumping flow rate. The air pressure depends on different pumping needs, but should not exceed 7BAR.
4. Installation height: Please fully consider the self suction capacity of the pneumatic diaphragm pump to avoid the problem of reduced self suction.
5. Pipeline: The pump position can only be determined after considering each possible location where pipeline problems may occur.
The installation of pneumatic diaphragm pumps should be selected at the connection of a short and straight inlet and outlet pipeline, and additional bends and pipe fittings should be avoided as much as possible. The pump body should be able to independently support all pipelines. Moreover, the pipelines should be arranged in an orderly manner to avoid stress on the pump body pipeline device. Flexible hoses can be installed to eliminate the stress caused by the natural reciprocating movement of the pump. If the pump body is to be connected to a fixed base, placing a buffer pad between the pump body and the base will help reduce pump body vibration.
