Diaphragm pump is a new type of pump widely used in chemical, food, medicine and other fields. Its unique structure and working principle make it have many advantages, such as leak-proof, corrosion-resistant, oil-free lubrication, etc., and can adapt to high viscosity, Special working conditions such as particles and easy crystallization. This article will introduce the working principle, advantages and application scenarios of diaphragm pump in detail, and provide some skills to help you get started easily. The working principle of the

diaphragm pump: The

diaphragm pump is a pump that uses an elastic diaphragm to compress and absorb the medium. It is mainly composed of a motor, a reducer, a diaphragm and a valve. Its working principle is that when the motor drives the reducer to rotate, the linkage mechanism and the diaphragm produce a push-pull effect, so that the diaphragm moves left and right, and completes a suction and discharge action in each working cycle. This isolation allows the medium to flow on both sides of the pump, avoiding any mechanical parts of the pump coming into direct contact with the medium. The advantages of

diaphragm pumps:

1. good leak-proof performance: diaphragm pumps use diaphragms to separate the inlet and outlet during work, and only use medium pressure to pump, without mechanical seals and fillers, so they can avoid pump leakage Problems, especially suitable for flammable, explosive and toxic media.

2. Strong corrosion resistance: The main material of the diaphragm pump is plastic and metal, which has good corrosion resistance and can adapt to various acids, alkalis, salts and other media.

3. Oil-free lubrication: When the diaphragm pump is working, the diaphragm plays the role of the piston and does not require lubricant lubrication, which avoids the risk of oil contamination and corrosion of the pump core components.

4. a wide range of application: diaphragm pump can adapt to high viscosity, with particles and easy crystallization and other special conditions, with a wide range of flow, high pressure and self-absorption capacity and other characteristics, suitable for chemical, food, pharmaceutical and other fields of a variety of process requirements.

diaphragm pump application scenarios:

diaphragm pump is widely used in chemical, pharmaceutical, environmental protection, food and other industries, especially suitable for conveying flammable, explosive, toxic, harmful media occasions, such as: sulfuric acid, chloride, nitric acid, organic solvents, paint, paint, acid and alkali. At the same time, it is also commonly used in chemical processes, such as the replenishment, unloading, transportation and recovery of reaction kettle, distillation equipment and filtration equipment.
Tips for
diaphragm pumps:

1. Check before installation: After unpacking, check whether the diaphragm pump is damaged and whether it lacks the required accessories.

2. Correctly place the pipeline: the inlet pipe and the outlet pipe of the diaphragm pump should not be installed backwards, and the shock-absorbing tripod should be firm, and the pump body should be placed horizontally.

3. Start and stop the pump: Before starting, the prime mover should be turned by hand to confirm that the pump can rotate and there is no abnormal sound. After starting, the pump should be pressurized gradually and its operation should be observed. Close the inlet and outlet valves before shutdown, and disconnect the power supply after step-by-step pressure reduction.

4. Pump maintenance and maintenance: regular cleaning and maintenance of the diaphragm pump, check the wear of the parts, timely replacement of worn parts. It is also necessary to add oil and lubrication to avoid parts that affect the service life of the pump due to friction and wear.

summary:

diaphragm pump is a new type of pump with high efficiency, reliability, energy saving and environmental protection. Its working principle is unique and its advantages are obvious. It is necessary to pay attention to details when using, such as reasonable selection of models, correct installation, standardized operation, regular maintenance, etc., in order to give full play to the advantages of this pump and bring more convenience to production and life.
