Pneumatic diaphragm pump installation steps and diagrams

Pneumatic diaphragm pump installation steps and diagrams

Pneumatic diaphragm pump is a new type of conveying machinery, the use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted . The main features of this pump pneumatic diaphragm pump, stainless steel pneumatic diaphragm pump, QBY pneumatic diaphragm pump.

Pneumatic diaphragm pump is a common chemical machinery industry, the purchase of the pump, if there is no dedicated technical staff to install, it is likely to delay the production, then we will briefly introduce the pump installation steps and the schematic diagram.

Pneumatic diaphragm pump suction pipe diameter of not less than the pump inlet port diameter, such as the delivery of high-viscosity fluid, the suction pipe diameter is preferably greater than the pump inlet diameter. Suction piping on the inlet side must be durable and free of wrinkles to create a high vacuum condition. The diameter of the outlet pipe should be at least equal to the outlet diameter or slightly larger to reduce the friction loss. All piping and fittings must be leak-tight or pump self-priming will be reduced.

Pneumatic diaphragm pump installation: If you ignore the installation details, a long period of careful planning, research and selection will still result in poor pumping effect and may affect the life of the pump.

Location: Noise, safety and other logic often have requirements for where the equipment should be installed. Parallel installation with conflicting requirements may result in blockage in the area of ​​use, affecting the installation of other pumps.

Use: First, the location of the pneumatic diaphragm pump must be easy to use, so that maintenance personnel will facilitate routine inspection and commissioning.

Air Supply: Each pneumatic diaphragm pump shall have a vent tube and the vent tube shall provide sufficient air volume to achieve the desired pump flow. Air pressure according to different pumping needs, but not more than 7BAR.

Installation height: Please take full account of the pneumatic diaphragm pump self-absorption capacity to avoid the problem of reduced self-absorption.

Piping: The pump position can not be finalized until after considering each possible location of the piping problem.

The best installation should be selected at the junction of a shortest and most straight import and export pipeline. Should try to avoid the extra elbow and pipe fittings facilities. The pump body should be able to support all piping independently. Also, the piping should be ordered to avoid stress on the pump piping. Active hoses can be installed to eliminate stress from the pump's natural movement back and forth. To attach the pump body to a fixed base, placing a cushion between the pump body and the base will help reduce body vibration. (The following is a schematic diagram)

Pneumatic diaphragm pump use matters needing attention:

Pneumatic diaphragm pump is a compressed air-powered, through the diaphragm reciprocating deformation volume changes caused by the volume of the pump, the working principle is similar to the piston pump. Pneumatic diaphragm pump according to certain principles and methods of use, in the specific use of the operating procedures in accordance with certain instructions and precautions to use, can produce an important role and contribution to use, play a good value for use. Pay attention to the following points when using the pneumatic diaphragm pump to operate and operate: Ensure that the maximum particles contained in the fluid do not exceed the maximum safety of the pump through the particle diameter standard. Tighten the pump and the connection pipe joints to prevent the pump in the vibration due to shock generated electrostatic spark. Use antistatic hose. To periodically check and test the reliability of the grounding system, the grounding resistance is less than 100 ohms. Maintain good exhaust and ventilation, away from flammable and heat sources. The inlet pressure should not exceed the maximum allowable pressure of the pump. Compressed air above the rated pressure of the pipe pump may result in personal injury, property damage and damage to the pump.

Electrostatic sparks may cause personal injury and property damage as a result of explosions. Use large enough cross-section conductors to properly and properly ground the grounding screw on the pump. Grounding requirements in line with local laws and regulations and the requirements of the scene some of the special requirements of the provisions. Pump exhaust may contain solids, do not face the work area or the exhaust port, to avoid personal injury. When the diaphragm fails, the material delivered by the blowdown pump will be ejected from the exhaust muffler. Ensure the pump pressure piping system can withstand the highest output pressure, to ensure multi-stage pump drive air system clean and normal working conditions. When transporting flammable and toxic fluids, take the outlet port to a safe place away from the work area. Use a minimum of 3/8 "ID OD tubing and muffler to smooth the wall.

High pressure fluids can cause serious personal injury and property damage. Do not perform any maintenance work on the pump and the pipe system while the pump is pressurized. If the rotor pump is to be repaired, cut off the intake air and open the pump The bypass pressure relief mechanism depresses the piping system and slowly loosens the connected pipe connections. Such as the transport of hazardous toxic fluid pump, fire pump, please do not pump directly to the manufacturer to repair. Liquid delivery Some pumps made of aluminum alloy, not for use with fluids containing Fe3 + and halogenated hydrocarbons and other halogenated hydrocarbon solvents, will cause corrosion which may cause the pump body to burst. Ensure that all parts in contact with the transport body will not be corroded by the fluid being transported. Ensure that all operators familiar with the operation and use of pump safety precautions, if necessary, the necessary protective gear. Correct use of the pump does not allow long-term air operations.
