■ QBYF typeFluorine lined diaphragm pumpDesign features:

1. Compressed air is used as power.
2. It is a type of displacement pump that causes a change in volume due to the reciprocating deformation of the diaphragm, and its working principle is similar to that of a plunger pumpdiaphragm pumpThe characteristics of the working principle, thereforediaphragm pumpHas the following characteristics:
(1) The pump will not overheat: compressed air is used as the power source, and during exhaust, it is a process of expansion and heat absorption. The temperature of the pneumatic pump decreases during operation, and no harmful gases are discharged.
(2) Will not generate electric sparks: Pneumaticdiaphragm pumpNo electricity is used as power, and grounding prevents static sparks
(3) It can be achieved through the use of liquid containing particles: because it works in a volumetric manner and the inlet isball valveSo it's not easy to get blocked.
(4) The shear force on the material is extremely low: how it is sucked in and expelled during operation, so the agitation of the material is minimal, suitable for transporting unstable substances
(5) The flow rate can be adjusted by installing a throttle valve at the material outlet.
(6) It has the function of self-priming.
(7) It can run empty without any danger.
(8) Can work underwater.
(9) The fluids that can be transported are extremely diverse, ranging from low viscosity to high viscosity, and from corrosive to viscous.
(10) There is no complex control system, no cables, fuses, etc.
(11) Small in size, lightweight, and easy to move.
(12) No lubrication is required, so maintenance is simple and there will be no pollution to the working environment due to dripping.
(13) The pump can always maintain high efficiency and will not decrease due to wear and tear.
(14) Energy utilization: When the outlet is closed, the pump automatically stops, causing equipment movement, wear, overload, and heating
(15) Without a dynamic seal, maintenance is easy and leakage is avoided. There are no dead spots during work.

■ Working principle of fluorine lined diaphragm pump:

In each of the two symmetrical working chambers of the pump, there is an elastic diaphragm installed. The connecting rod integrates the two diaphragms into one. Compressed air enters the distribution valve from the pump's intake head and pushes the diaphragms in the two working chambers, driving the two diaphragms connected by the connecting rod to move synchronously. At the same time, the gas in the other working chamber is discharged out of the pump from behind the diaphragm. Once reaching the end of the journey. The valve mechanism automatically introduces compressed air into another working chamber, pushing the diaphragm in the opposite direction, thus forming synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two unidirectional devicesball valveThe reciprocating motion of the diaphragm causes a change in the volume of the working chamber, forcing two unidirectional directionsball valveAlternating opening and closing to continuously suck in and discharge liquid.

■ Performance parameters of fluorine lined diaphragm pump:

■ Instructions for using fluorine lined diaphragm pump:

1. When transporting fluids that are prone to sedimentation and freezing, when the pump is not running for a period of time, it is necessary to rinse the inside and outside of the pump with a suitable solvent before stopping to avoid blockage and damage.
2. If the pump needs to be stopped for several hours during operation, please cut off the compressed air.
3. It can be adjusted pneumaticallydiaphragm pumpAdjust the flow rate of the pump by adjusting the pressure and flow rate of the compressed air. You can also adjust the flow rate of the feed to control it. Please do not use hoses or feed pipes with too small a diameter to avoid excessive suction resistance and blockage of the feed pipe.
5. It is recommended to install all shut-off valves at the compressed air inlet of the driving pump when feeding with positive pressure.
6. Pleasediaphragm pumpThe pump should be securely installed to prevent vibration damage during operation.

■ Precautions for operating fluorine lined diaphragm pump:

(1) QBYF type fluorine lined pneumaticdiaphragm pumpStart stop load operation: pneumaticdiaphragm pumpIt is driven by a variable frequency motor. In order to avoid the occurrence of excessive or insufficient load during start-up and shutdown, it is strictly required to control the start-up and shutdown load at around 30%, and the instrument is set to ensure that the increase or decrease of load must be completed within a certain period of time, effectively maintaining the variable frequency converter from a technological perspective.
(2) QBYF type fluorine lined pneumaticdiaphragm pumpInstrument air and lubricating oil pressure system operation: pneumaticdiaphragm pumpThe pressure of the instrument air and lubricating oil is interlocked with the main motor. The injection and discharge valves of the propulsion fluid are air closed valves, and a certain air pressure must be maintained at all times. The minimum operating pressure of the two valves is not less than 0.4MPa, so the instrument air pressure is generally maintained above 015MPa. Even after stopping the pump, the instrument air is not stopped to prevent insufficient or excessive liquid in the propulsion fluid chamber from being suppliedvalveThe air is filtered and atomized with oil. pneumaticdiaphragm pumpDuring operation, the lubricating oil pressure should not be lower than the pressure interlock value (0115MPa), and the pressure difference of the lubricating oil outlet filter should not be too large. The steel ball inside the lubricating oil flow sight glass should be at the upper limit position. When adjusting this flow rate, the adjustment amplitude should not be too large to avoid instantaneous excessive flow and rapid pressure drop, which may cause interlock tripping. By improving the above process and mastering the operation points proficiently, the pneumatic system can be improveddiaphragm pumpThere is always a stable process environment during operation. After more than a year of operation, there has only been one trip due to electrical reasons, achieving long-term, safe and efficient operation.
