What are the advantages and disadvantages of membrane pump compared to ceramic piston pump? 10

Advantages of Huaxing ceramic piston pump:

1. Wear resistance: The plunger is fired from alumina ceramics and made of fine grinding, with a hardness of more than one and a surface roughness. There is no shear movement of the plunger and conveyed material. It is suitable for conveying materials containing sand and solid particles.

2. Strong self-priming ability: plunger vacuum method, self-priming capacity of 4-8 meters (the proportion of material determines the change of suction stroke).

3. Adjustable constant pressure automatic variable: the working pressure of the plunger mud pump is adjustable, and it can be adjusted arbitrarily within the range of 0-20 kg, and the adjusted pressure will not change due to the change of the output flow of the pump, and the set pressure will remain unchanged, even if the outlet of the running pump is turned off, the pressure will not change. (The variation cannot exceed the maximum flow rate of the pump, the flow rate can be zero).

4. High pressure and high efficiency: the maximum pressure of ordinary models is 20 kg. At a pressure of 5 kg and the same flow rate, the motor power of the plunger slurry pump is 1 to 2 models smaller than that of other types of pumps.

5. Simple operation: the pressure adjustment only needs to tighten or relax the pressure regulator, and the pressure is locked after adjustment, and there is no need to adjust it in the future.

6. Low cost: The wearing parts of the pump are valve plate and plunger seal. The replacement cycle is once every 3-6 months for ceramic sludge and 6-12 months for municipal sludge.

7. Long service life: at least 15 years.

8. Customized production: According to the actual working conditions of each user, flexible configuration, customized products that are most suitable for customer production needs.

Both can be used to convey liquid media containing small amounts of small particles.

The membrane pump has no leakage, but the pressure is relatively low (i.e., discharge pressure); Ceramic piston pump.

There is a small amount of leakage, but the outlet pressure can reach 50MPa

The structure of the membrane pump is more complex, and the structure of the ceramic piston pump is simple, but the cost of spare parts is high.

To sum up, diaphragm pumps are suitable for conveying corrosive media and media containing solid particles, with simple maintenance but small delivery flow; Piston pumps are suitable for conveying high-pressure, high-viscosity media, with large flow rates but complex maintenance.

The difference between piston pump and diaphragm pump is: different working principles, no cost performance, and different requirements for the purity of the conveyed material.

1. The working principle is different:

The diaphragm pump relies on the reciprocating motion of the connecting rod to drive the diaphragm deformation to suck the material in and out of it; The piston pump relies on the reciprocating motion of the plunger in the cylinder block to change the volume of the sealing working cavity to achieve oil absorption and oil pressure.

2. Cost-effective:

The diaphragm pump has a simple structure, small size, light weight, and is relatively cheap and has low maintenance costs; The piston pump has a complex structure, high environmental requirements, and high maintenance costs.

3. Different requirements for the purity of conveyed materials

Diaphragm pumps can convey impurities and viscous materials, while piston pumps have higher requirements for the cleanliness of materials.

First, the nature is different.

1. Diaphragm pump properties: with the help of the membrane, the liquid will be separated from the live column and the pump cylinder, so as to protect the live column and the pump cylinder.

2. Piston pump nature: an important device of hydraulic system.

Second, the working principle is different.

1. The working principle of the diaphragm pump: it relies on the back and forth agitation of a diaphragm to change the volume of the studio to suck in and discharge liquids.

2. The working principle of the piston pump: the total stroke l of the reciprocating motion of the plunger pump is unchanged, which is determined by the lift of the cam. The amount of oil supplied to each cycle of the plunger depends on the supply stroke, which is variable and not controlled by the camshaft.

The start time of the oil supply does not change with the change of the oil supply stroke. Turning the plunger can change the end time of the oil supply, thus changing the amount of oil supplied. When the piston pump is working, under the action of the cam and plunger spring on the camshaft of the fuel injection pump, the plunger is forced to move up and down to complete the pumping task.

The pressure ratio of the diaphragm pump is generally 1:1, while the pressure of the piston pump can reach 22:1, the diaphragm pump is suitable for conventional spraying, and the piston pump is used for large high-pressure spraying.

Diaphragm pump: Diaphragm pump or membrane pump, also known as pneumatic diaphragm pump or air operated double diaphragm pump. A type of reciprocating pump, which uses elastic film, corrosion-resistant rubber or elastic metal sheet to divide the pump into two parts that are not connected to each other, which are the areas where the liquid to be conveyed and the live column exist.

In this way, the live column does not come into contact with the conveyed liquid. The reciprocating motion of the live column is transmitted to the diaphragm through the medium on the same side, so that the diaphragm also reciprocates, so that the conveyed liquid can be sucked in and discharged through the spherical valve. The only part of the diaphragm pump that comes into contact with the liquid being conveyed is the spherical valve, which is easy to make a form that is not affected by the liquid.

In industrial production, diaphragm pumps are mainly used to convey corrosive liquids or liquids containing suspended solids.

1. The working principle is different: the diaphragm pump relies on the reciprocating motion of the connecting rod to drive the diaphragm deformation to suck the material in and out of it; The piston pump relies on the reciprocating motion of the plunger in the cylinder block to change the volume of the sealing working cavity to achieve oil absorption and oil pressure. 2. Cost-effective:

The diaphragm pump has a simple structure, small size, light weight, and is cheaper than socks and low maintenance costs; The structure of the column accompaniment plug pump is complex, high-quality, has high environmental requirements, and the cost of maintenance is high. 3. Different requirements for the purity of the conveyed material: the diaphragm pump can convey impurities and viscous materials, while the piston pump has higher requirements for the cleanliness of the materials.

Embolic pumps are more durable.

The diaphragm pump has a simple structure, small size, light weight, low cost, average quality, low protection cost, complex piston pump structure, high price, high environmental requirements, good quality, high protection cost, so the embolic pump is more durable.

Advantages of embolic pumps:

The closed working volume of the embolic pump is composed of a plurality of plungers in the cylinder body and the plunger holes in the cylinder body, and the plunger and the plunger holes in the cylinder are cylindrical surfaces, and its machining accuracy is easy to ensure in the spike, it has the advantages of light weight, compact structure, good sealing, high working pressure, and can still maintain high volumetric efficiency and total efficiency under high pressure closed training, and it is easy to realize variables.

Disadvantages of embolic pumps:

The pollution of the hydraulic working medium is more sensitive, the oil filtration accuracy is high, the structure is complex, the processing accuracy and the daily maintenance requirements are relatively high, and the first is more expensive. It cannot convey corrosive, volatile, flammable and explosive mediators. Due to the high intensity of work, it will be easy to cause leakage.

There is no safety pressure relief device, which needs to be installed separately. <>

Summary. We are happy to serve you if the liquid you want to handle contains solid particles or has a high viscosity, diaphragm pumps are relatively suitable; If higher conveying accuracy and a wider range of applications are required, piston pumps are even better.

If the liquid you want to deal with contains solid body particles or has a high viscosity, the diaphragm pump is relatively more suitable than Kaibi; If higher conveying accuracy and a wider range of applications are required, piston pumps are even better.

Diaphragm pumps and piston pumps have their own characteristics and are used in different scenarios, and which one is better depends on the specific situation. Diaphragm pump is a type of pump that realizes the suction and release of liquid into hail core through the compression and relaxation of diaphragm. The diaphragm pump is simple to operate, compact in structure, not easy to leak, easy to maintain, and suitable for conveying difficult media such as solid particles and high viscosity, easy to crystallize or radioactive.

However, the diaphragm pump needs to use a loose diaphragm, and the diaphragm often needs to be replaced, so it is suitable for conveying dirty and messy fluids containing sediment, sand, particles, viscous matter, etc., and does not require a large flow rate. The piston pump uses quantitative rotation to press the liquid into the flow channel to complete the transportation, and the quantitative conveying has high precision and good stability. Piston pumps can convey special media such as mud, drilling fluids, cement and concrete, as well as common liquids, and are more versatile.
