The meaning of the diaphragm metering pump model marking

Can't you solve a problem for someone else except to advertise? Is there a minimum pressure requirement for diaphragm metering pumps? served.

800 should be the rated flow rate of 800l h, the actual maximum flow should be slightly greater than 800, estimated between 850-900, generally refers to the rated pressure of the pump, the back, to be honest I don't know what it means, however, some old manufacturers like to use numbers in the back to indicate the material category, which may represent the material and pump inlet and outlet interface form. The meaning of J5 is obvious, J refers to the metering pump, 5 refers to the No. 5 base (the definition of the base is also different, some in order, some according to the plunger force, look at this model, it should be in order 1 is the microcomputer base, 2 is the small base, 3 is the medium base, 4 is the large base, 5 is the extra-large base, some manufacturers use jw, jx, jz, jd, etc.), M refers to the diaphragm type.

As for the power, it's hard to say, according to this flow and pressure, the power should be in, and the speed is generally about 120 times, which will not be too bad.

Agree with Piggy.

It's pressure. Not very clear.

The flow rate is 800 l h

In fact, it is best to ask the manufacturer directly, and the number of different manufacturers is different.

It is best to look at the random information of the manufacturer, each manufacturer number is different, some indicate the head or outlet pressure, some indicate the impeller diameter and so on. If the conditions are given to the full power can be calculated, if it is not too old equipment, the nameplate on the pump body can be found in the relevant information.

We also do metering pumps, Shanghai Chunjiang brand.

J5-M, I don't know what it means, it should be the code name of a manufacturer.

The manufacturer's name is JYZR800

800L H, it should be MPA, this depends on your specific requirements.

Abstract:The working principle of the diaphragm metering pump is to use the diaphragm that is easy to deform to separate the medium hall family from the reciprocating working mechanism, so as to achieve the purpose of completely eliminating the leakage. It has no leakage in the conveying process, is suitable for conveying dangerous media, has a large clearance volume, and has a low volume coefficient; The radial size is large, and the structure layout is difficult.

Let's take a look at what is the working principle of the diaphragm metering pump and what are the characteristics of the diaphragm metering pump. 1. What is a diaphragm metering pump?

The diaphragm metering pump uses a specially designed and processed flexible diaphragm to replace the piston, and realizes reciprocating motion under the action of the driving mechanism to complete the process of suction and discharge. Due to the isolation effect of the diaphragm, the isolation between the metered flow-sensitive body and the driving lubrication mechanism is truly realized in the structure. The high-tech structural design and the selection of new materials have greatly improved the service life of the diaphragm, coupled with the excellent corrosion resistance characteristics of composite materials, the diaphragm metering pump has become the main pump type in fluid metering applications.

2. What is the working principle of the diaphragm metering pump?

Diaphragm metering pump can be used to completely avoid leakage when transporting flammable, explosive, highly toxic and other dangerous media. The working principle of the diaphragm metering pump is: the diaphragm that is easy to deform is used to separate the conveyed medium from the reciprocating working mechanism, so as to completely eliminate the leakage.

3. What are the characteristics of diaphragm metering pumps?

1. No leakage, especially suitable for conveying dangerous media; Cheating.

2. In order to overcome the elastic deformation of the diaphragm in the suction process, the hydraulic diaphragm metering pump also needs to consume a certain amount of energy, so the suction performance is worse than that of the plunger metering pump;

3. The clearance volume of the diaphragm metering pump is large, and the volume coefficient is low due to the deformation of the diaphragm under the force;

4. In order to ensure the life of the diaphragm and improve the volumetric efficiency, the reciprocating times of the diaphragm metering pump are usually low, in most cases, n 100 times;

5. The radial size of the diaphragm metering pump head is large, and when the flow rate is too large, the structure layout is difficult, so the flow rate of the diaphragm metering pump is small;

6. Limited by the strength of the diaphragm, the discharge pressure cannot be very high. If there is no power supply in the environment, an electromagnetic diaphragm metering pump can be used.

The parameters that need to be paid attention to when selecting the model are:

1.Flow rate: The metering pump needs to select the corresponding model and specification according to the flow rate of the medium to be conveyed.

2.Pressure: Determine the maximum pressure required according to the nature of the conveying medium, the conveying distance, etc., to select the appropriate model and specification.

3.Viscosity: Different media viscosity also has a certain influence on the selection of metering pumps.

4.Temperature: According to the temperature of the medium, choose a model that is resistant to high temperature or low temperature.

5.Physical properties: There are also certain differences in the physical properties of different media, such as density, viscosity, pH value, etc. of different media.

6.Special requirements: Some special requirements also need to be considered, such as the need for corrosion resistance, wear resistance, etc.

1.Determine the material.

The common main materials are:

Cast steel, ductile iron, aluminum alloy, stainless steel (304 316), plastic PP polypropylene, fluoroplastic (PVDF), should be selected according to the nature of the material conveyed in the chamber.

Non-corrosive materials are generally made of cast iron, ductile iron or aluminum alloy, and corrosive liquids are made of stainless steel, plastic or fluoroplastic according to the degree of corrosion. You can refer to the corrosivity parameter table of the material.

In the case of uncertainty about the characteristics of the material, it is recommended to choose a material that is consistent with the conveying pipeline.

The material of separator, ball and ball seat is divided into three ways, Teflon, polyether, etc., which should be selected according to the corrosiveness, abrasion and temperature of the material.

2.Determine the model number.

Choose the size of the air-operated diaphragm pump, which can be selected according to the flow rate or caliber.

The indicated flow rate of the pneumatic diaphragm pump is the test value under the condition of 0 suction stroke and 0 head under the pressure of 7 kg of compression force, and the actual flow rate should be estimated according to the working conditions.

If the diameter and flow do not match, a reducer can be installed at the inlet and outlet.

Pneumatic diaphragm pumps are positive displacement pumps that have a low shear of the material and can convey materials with particles. However, the size of the particles to be conveyed must be smaller than the diameter of the particles that can pass through the pump. For details, please refer to the model performance parameter table.

3.Determine the viscosity of the material.

When conveying materials with viscosity, you should choose a pump that is one size larger than the required flow rate, because the flow data of the pneumatic diaphragm pump is calculated by the clear water test, and the greater resistance of the viscous material will make the flow rate smaller.

4.The category of material being conveyed.

When using an air-operated diaphragm pump to transport materials with high hygiene requirements for food or medicine, a sanitary air-operated diaphragm pump made of stainless steel should be selected.

1.Safe operation, mechanically driven diaphragm.

2.Good sealing, no leakage, simple and safe assembly and maintenance.

3.It can convey highly viscous media, corrosive liquids and hazardous chemicals.

4.The flow rate is adjusted enough to adjust the stroke length or motor frequency.

Hello, I am glad to serve you and give you the following answers: Yes, diaphragm pump is a kind of instrumentation equipment, it is a pump used to transport liquid, its working principle is to control the flow of liquid through a diaphragm, so as to achieve the purpose of transporting liquid. The reason for the problem:

1.The structure of the diaphragm pump is unreasonable, which leads to poor liquid flow, which affects the efficiency of the noisy air pump. 2.

The operating pressure of the diaphragm pump is too high, which causes the flow of liquid to be blocked, which affects the efficiency of the pump. 3.The diaphragm pump has insufficient lubricating oil, which causes the flow of fluid to be blocked, which affects the efficiency of the pump.

Workaround and practice steps:1Check the structure of the diaphragm pump to ensure that the structure is reasonable to ensure the smooth flow of the liquid body.

2.Check the working pressure of the diaphragm pump to ensure that the pressure is appropriate to ensure that the liquid flows smoothly. 3.

Check the lubricating oil of the diaphragm pump to make sure there is enough lubricating oil to ensure that the liquid flows smoothly. Personal Tips:1

When using diaphragm pumps, attention should be paid to checking the structure, working pressure and lubricating oil of the pump to ensure the normal operation of the pump. 2.When using the diaphragm pump, you should pay attention to check the lubricating oil of the pump to ensure the normal operation of the pump.

3.When using the diaphragm pump, attention should be paid to check the working pressure of the pump to ensure the normal operation of the pump.
