JOFEE 3-inch aluminum alloy diaphragm pump

JOFEE 3-inch aluminum alloy diaphragm pump-Application examples

1. Cleaning the bottom of the oil tank, although there is a cushion method for oil pumping, cannot guarantee that the oil will be completely pumped out, and there will always be at least 3-5mm thick oil layer left on the surface. Taking a 5000m3 oil tank as an example, approximately 1-1.5t of oil is lost each time. For oil tanks with low-level dehydration tanks, although the remaining oil and water can be discharged to the oily wastewater treatment plant for recycling, the volatile oil products are mostly evaporated during transportation and pollute the environment.
2. During the process of oil refining production scheduling, temporary tank dumping, loading and unloading, and oil sampling are often required for oil products. Alternatively, in order to avoid contaminating normal pipelines, connecting temporary pipelines with a diaphragm pump can quickly and conveniently accomplish this task.
3. A 3000t oil tanker is unloaded using a fixed screw pump for bottom oil recovery. At least 50t of oil should remain between the warehouse partitions. If a larger displacement isolation pump is used, good results can be achieved.
4. The transportation of gas and hydrogen sulfide residue at the bottom of the refinery flare requires centralized discharge and treatment of gas residue and sulfur-containing water, otherwise it will form acidic corrosion equipment.

JOFEE 3-inch aluminum alloy diaphragm pumpThe components mainly consist of pneumatic motor, liquid cover, diaphragm assembly, ball valve assembly, inlet and outlet pipes, muffler and other parts.

1. Pneumatic motor: mainly composed of three parts: motor body, main valve, and reversing valve. The improved part is a device that converts the energy of compressed air into reciprocating kinetic energy, which is the basic and main component of diaphragm pumps.

2. Liquid cap: Combined with the motor body (or gas cap) to form a cavity.

3. Diaphragm assembly: composed of diaphragm connecting rod, diaphragm gasket, diaphragm bolt, corresponding O-ring, and diaphragm. The diaphragm divides the chamber into an air chamber and a flow chamber, and the diaphragm component reciprocates under the action of the pneumatic motor, thereby forming a pressure difference between the air chamber and the fluid chamber.

4. Ball valve assembly: consisting of a ball valve, ball seat, and corresponding O-ring seal, it functions as a one-way valve.

5. Inlet and outlet pipes: only used as pipelines for fluid to enter and exit the pump body.

6. Muffler: Reduce the noise generated during pump operation.
