Use of magnetic gear pump in the filling machine industry
The cream emulsion without particles, viscosity 5000 cps and below the sticky material, water liquid, such as lubricating oil, detergent, detergent, honey, etc., can be used, can not contain particles, especially metal particles, will wear gear. For materials with high viscosity, samples can be sent to the company for testing. For strong corrosion materials such as toilet washing detergent cleaning, 316L pump cannot be used, and corrosion resistant pump must be used. For high temperature materials, the company's gear pump can adapt to 0-120℃, which also thanks to the company's precision machining ability, precision size machining accuracy, advanced design ability, rich experience to ensure that the gear pump will not be stuck in the case of high temperature materials, materials below 80℃ can be used directly, 80℃ -120℃ material, need to report to the factory, the pump after high temperature test. For heating liquidity but cooling solidification material, need to ensure that the pump filling is hot, can put the pump in the machine design in the heating solution, insulation not done, the curing material will break the gear, like aromatic, chocolate, cooling oil and other materials can take the pump body placed in the heating solution or hot water tank. Because the magnetic gear pump material is completely packaged without leakage, so toxic, flammable and explosive materials can also be used, but flammable and explosive materials need to use explosion-proof motor.
Select the magnetic gear pump model according to the flow: select according to the single filling volume and the number of filling times per minute, such as 5L material each time, 10 times a minute, because the filling is intermittent, then the gear pump with a flow rate above 90L / minute can be selected. The pump body material for filling industry is preferred 316L, gear material PEEK, more wear and corrosion resistant. Drive can choose servo motor, brush motor, brushless motor, stepper motor, explosion-proof motor. Connectors according to the actual situation can be selected. Most of the pneumatic closed water nozzle in the outlet, and a few use the final motor reversal to achieve leakage prevention. For materials with large viscosity, it is better to use hopper, direct suction may not move, the hopper should be replenished in time, because in the middle of the viscosity of bad fluidity may form a hole, resulting in direct pumping into the air. Large viscosity can also choose a large flow of the square pump gear pump, the suction force is greater. Aduncertain viscosity to send the material to the company for free testing.
Motor selection of magnetic gear pump: gear pump drive according to the need can choose servo motor, brush motor, brushless motor, stepper motor, explosion-proof motor. Why with different motors, the flow rate will be different? This is because there are brush motor 6000 rpm, brushless motor 4500 rpm, servo motor 3000 rpm, step motor 1000 rpm, different speed so different flow. For the selection of motor, according to their practical accuracy requirements and economy, high cost effective choose brush motor, brush motor is cheap, but only one percent, brush motor can only match governor, can not use PLC control; long life, choose brushless motor; small flow, large torque, accuracy five thousand, select step motor; precision within three thousand, wide speed range, select servo motor, servo motor except expensive, other are good. Brushless, stepping and servo motor can be controlled by PLC. Choose brushless motor, need 485 communication, the factory can be with communication motor, including drive, standard line 1.4 meters, can match 3 meters long line, the factory use is the TST 42-40P column of integrated motor products, integrated motor is the perfect combination of drive and stepping motor, it is a perfect fusion of stepping motor and drive technology, not only can save installation space, the wiring complex for simple at the same time. Using servo motor, the factory standard with aluminum motor seat, such as 7.5L large round pump, with 400W 60 servo, general servo motor are standard, motor shaft is 14mm, but there are exceptions, such as Panasonic servo, so in the case of self-servo, it is recommended to measure the motor shaft. Non-standard motor seat factories can also be customized.
Summary of the Magnetic gear pump problems:1. Can the standard brush motor automatically adjust the quantity?Yes, the customer just has the governor. There are brush motor has 2 lines and 5 lines, generally with 2 lines, the requirements of 5 lines to put forward first.2. How is the accuracy of the standard brush motor?rush motor accuracy of 1%

5. Is 1L enough for the factory test?
1L is not enough, and 2L is stable, because the test needs to absorb a section of pipe, especially in the case of not enough thick material, it is easy to pump air to affect the measurement accuracy.
6. How is the metering accuracy of your gear pump?
We promise the accuracy of the servo motor. However, there is customer feedback that the accuracy of our gear pump reaches one in a thousand, and the assembly line achieves two per thousand. This is different from the coordination of materials, filling speed and machines.
7. Why is the servo motor 60 pump only 45L per minute and the 90 pump only 78L per minute?
This is because at that time, the model design was designed according to the brush motor, the brush motor speed is 6000rpm, the brushless motor is 4000rpm, and the servo motor speed is only 3000rpm, so the flow of the brushless motor and servo motor will be lower than the brush motor.
8. Why is the pump body 316L and the gear using high strength engineering material PEEK instead of stainless steel?
The friction between stainless steel and stainless steel, will be greater than the friction between stainless steel and plastic, metal and metal, easy to have iron filings. The intensity of PEEK is fully sufficient.

Want to use your gear pump filling lubricating oil, do not want to use a hopper, directly into the bucket can smoke?
Mainly depends at the viscosity, the number of lubricating oil is not the same viscosity is not the same.
44. The 3D model you give does not indicate the direction of incoming and outgoing materials. Our designers need the direction of incoming and outgoing materials for design.
This is the kind of our square pump, all of our square pumps, are in this direction.
45. With customer reaction, with other people's gear pump in use, the feed pipe has bubbles
question:
Solution: the pipe should be added clamp to prevent water leakage, which will be much better.
The pump can not be used as a valve, no one-way valve and pneumatic closed water nozzle, there will be reflux phenomenon. The pump seal must be well prepared. Feed port, or material barrel material requires no bubbles.
46. We used to use someone else's gear pump, want to order your 3L pump with a brush motor,
Our original joint is an 8. How much is your joint? Can we do what we want about it? We match the pagoda joint outer diameter 10, you can do according to your requirements of the outer diameter 8 joint, the installation size can also be done according to your original, a brush motor 2 lines or 5 lines can also come according to your requirements.
47.1.5ml/rev Pump head with a stepper motor, we use a low speed for measurement
After the test, the accuracy range of each run met the requirements, but the calculation found only
There is 1.2ml / rev, why is this? This 1.5ml / rev is the theoretical displacement, but the magnetic pump has a volume efficiency in it, the lower the speed, the volume efficiency is relatively low, so the actual flow will be lower than the theoretical value, the lower the speed, the more obvious. Generally speaking, it is the internal of the gear pump because of the gap, the fluid leakage, the speed is low when the leakage is relatively obvious. So when we calculate the selection for our customers, such as 1 LX and 20 bottles per minute, we have 60 pumps and 48L per minute. One is volume efficiency, the other is intermittent pause time, we are all doubled. If you have several filling volumes, we will calculate the maximum filling volume. In our small pump is generally small filling volume, viscosity is large and take the square pump irrigation small filling volume, square pump flow large suction force.
48. We want to use your magnetic gear pump with UV glue, the viscosity is about 3000 cps, ok?
Uv glue is also known as photosensitive adhesive, ultraviolet light curing glue, shadowless glue is a kind of adhesive that must be cured by ultraviolet light irradiation. This kind of glue is solidified by light, so it is feasible to fill with gear pump, because the light will solidify, indoor also want to avoid light as far as possible, the pipe must be opaque black pipe, the viscosity must be ingredients bucket. Stop for a day or two is nothing, long-term or dry, the machine sealing is not so good, must be cleaned, hopper, pipe, gear pump, and so on are to be cleaned, otherwise there are solidified particles and blocks, it will be broken gear. Hopper can add cleaning solvent with a pump, hit a few cycles, and then open wash. This glue with either method, such as the piston type, can also have this cleaning problem.
49. Our material viscosity is relatively large, I want to use your magnetic gear pump, is a multi-head filling, I want to use a hopper, through multiple material pipes to multiple pumps, is it feasible?
This is not good, a hopper through multiple material pipes to multiple pumps, the viscosity of the material liquidity is not very good, will lead to uneven material absorption, resulting in inaccurate measurement. It is suggested to make a rectangular material box, with the stainless steel pipe under the pump, and ensure that the material box is continuously fed.
Above is the wrong usage
The figure above is the correct usage
50.I would like to ask, with your magnetic gear pump with brush motor, different pump 60W brush motor and 225W brush motor, can use the following controller?
