How to extend the service time of high viscosity gear pump?
The transport medium is not only an intermediary for energy transfer, but also a lubricant, seal and heat transfer medium. Gear pumps that deliver high viscosity liquids should deliver the most flow at lower power, less leakage, and greater pressure. The viscosity of the liquid reflects the ease with which the medium flows. Too high viscosity increases internal frictional resistance, reduces output power, wastes energy, and produces excessive system temperatures. When determining the medium to be transported, the product specification should be strictly followed, and the fluid medium recommended by the manufacturer should be used as much as possible, and the operating temperature range of the system should be considered. The viscosity index of the transport medium should be higher when it is desired to use it over a wide temperature range. When the viscosity of the transport liquid is high, or when the system is operating in a cold environment, it must be ensured that the transport medium can flow smoothly. Many oils contain waxy components that are easily crystallized at low temperatures and the transport medium should have a freezing point below the expected minimum operating temperature. In addition, the medium to be transported must be compatible with the rubber material such as seals, gaskets, hoses, etc. in the system. If the two are incompatible, the transport medium must be redefined.
Noise problem
In fluid delivery systems, rapid changes in flow velocity, flow and pressure, bubble collapse and alternating loads are common causes of noise, and gear pumps that deliver high viscosity liquids are the primary source of system noise.
Reasonably determine the working speed of the gear oil pump, so that the rotation of the gear and the shaft avoids the meshing resonance frequency, which can prevent the noise from increasing. This is because resonance occurs easily when the meshing frequency is close to the natural frequency of the gear train. The use of appropriate vibration isolation technology can prevent vibration from being transmitted to adjacent structures. To this end, the gear pump and the drive motor should be connected by a flexible coupling and installed on the same bottom plate to ensure coaxiality. The bottom plate is mounted on the elastic support to further improve the vibration isolation effect. It is an effective means to control the noise of the high viscosity gear pump by providing an expansion chamber or accumulator on the outlet pipe of the gear pump to absorb the pressure pulsation of the pump or the sudden change of pressure in the buffer line.
In general, the maximum allowable noise of a high-viscosity pump operating in the open air should be less than 90 decibels, otherwise the source of noise should be actively or passively contained, while reducing the time required for workers to directly expose to noise. If you are unable to control the noise, you should also take hearing protection measures. Once the high-viscosity gear pump has abnormal noise during operation, it should be stopped immediately.
Selection of working pressure
The rated pressure of the pump refers to the maximum allowable pressure when the pump is continuously operated, and the working pressure is determined by the external load. The life of the pump is directly related to its working pressure. For gear pumps that do not work frequently, the working pressure can be taken as the rated pressure of the pump. Considering the difference in product quality, it is best to reduce the rated pressure by 20% to 30%. For gear pumps that are often operated at higher pressures, the operating pressure should be one to two pressure levels lower than the rated pressure of the pump. Petrochemical equipment is often operated continuously for 24 hours. At this time, the working pressure of the pump should be much lower than the rated pressure, and the working speed should also be lower than the rated speed. If the working pressure of the high viscosity pump is adjusted too high, the gear pump will operate under overload.
Why can the high-viscosity gear pump produced by the saiken pumps industry completely replace the American Viking pump?
High-viscosity gear pump working principle: The high-viscosity pump is a volumetric internal gear pump. When the driving gear (outer rotor) drives the driven gear (inner rotor) to rotate, it constantly creates a closed space. In the oil suction zone, the gear gradually disengages and the liquid continuously It is filled with teeth and brought to the oil discharge area, and the liquid is discharged when the gear enters the engagement zone. The two rotating gears work together to form a stable volume displacement without pulsation. Since the pump is completely symmetrical, the pump can be reversed and the direction of the flow changes. However, it should be noted that the steering of the pump may be limited by the seal or other structures in the pump. When the user has a reversal request, it should be stated when ordering.
Advantages of conveying media:
The high-viscosity gear pump can transport high-viscosity, high-concentration, non-solid particles or fine soft particles of lubricative medium; high efficiency, stable performance and long service life. The high-viscosity pump can adopt the insulation jacket structure, which can heat the high-viscosity pump when conveying relatively high viscosity materials, thereby reducing the viscosity of the medium and achieving better conveying effect, while the single-screw pump has no insulation jacket structure; the high-viscosity pump After using for a period of time, if the internal clearance of the pump is worn, the pump gap can be adjusted according to the viscosity of the material conveyed by the high-viscosity pump without disassembling the pump. After adjustment, the pump can achieve good results. The high viscosity pump can be equipped with a safety valve. When the pump or piping system is overpressured, the safety valve opens to form an internal recirculation to ensure system safety. The single screw pump can not be installed in the pump itself, and can only be set in the pipeline, which increases the equipment input cost and installation cost. When choosing a high-viscosity pump, the viscosity of the medium delivered by the high-viscosity pump must be considered in order to determine the speed range of the high-viscosity pump. According to the speed range of the high-viscosity pump and the normal flow range of the high-viscosity pump under the required working conditions, Determine the specific model of the high viscosity pump. It should be noted that general media can be selected this way. Among them, some special media will change its composition at a certain temperature, so it is necessary to pay special attention to whether the pump speed is suitable when selecting a high viscosity pump, because the higher the pump speed, the greater the heat generated during normal operation. The limited temperature causes damage to the much transported media. There are also some food-based media, such as jams, like the jams we eat in our daily life, peanut butter, bean paste, etc. These media require that we must not destroy the internal components of the process during the transportation process, which requires us to choose The pump speed must be low to ensure that the high viscosity pump does not damage the delivered media during transport. High-viscosity pumps often have stuck and hold shafts during operation. The main reason is that high-viscosity pumps are often transported with high-viscosity media, and some have a mixture of impurities. If a suitable filter is not installed at the inlet of the pump, once the larger hard particles enter the pump chamber, the inner and outer rotors of the high-viscosity pump will be stuck, so that the pump will not move, and the inner and outer rotors of the high-viscosity pump will be seriously Destroyed
What are the precautions in the daily use of the magnetic drive pump?
1. If the solid medium is contained in the medium to be transported, the filter should be added to the inlet of the magnetic drive pump:
If it contains ferromagnetic particles, a magnetic filter is required.
2. The ambient temperature of the magnetic pump should be less than 40 during use, and the temperature rise of the motor should not exceed 75.
3. The cooling and lubrication of the magnetic drive pump bearing is based on the medium being conveyed;
Therefore, it is absolutely forbidden to operate at a low speed, and at the same time, avoid the time-and-load operation caused by the power failure after the power is turned off.
4. For the medium which is easy to precipitate and crystallize the transport liquid, it should be cleaned in time after use, and the liquid in the pump should be drained.
5. After 1000 hours of normal operation of the magnetic pump, the wear of the bearing and the end moving ring should be disassembled and the consumables that should not be reused should be replaced.
6. The medium to be conveyed and its temperature should be within the allowable range of the pump material.
The operating temperature of the engineering plastic pump is <90, and the operating temperature of the fluoroplastic pump is <120;
The conveying suction pressure is not more than 0.2MPa, and the maximum working pressure is 1.6MPa;
A liquid containing no hard particles and fibers having a density of not more than 1600 Kg/m 3 and a viscosity of not more than 30×10 −6 m 2 /s.
What are the requirements for the installation of the magnetic pump?
Do not force the pipe into place when installing the pipe.
If the pipe is configured in this way, it will bring stress and space to the magnetic pump and cause a deviation between the pump and the motor.
Pipe stress can also adversely affect the reliability of the magnetic drive pump.
If the pipe is cleaned or purged after installation, the suction and discharge ports of the pump must be sealed with blind plates.
According to the requirements of pipeline installation, pay attention to the following matters when configuring the pipeline and installing the pump.
Pipe installation requirements for magnetic drive pumps:
1. All suction and discharge pipes must be individually supported or hoisted and naturally lined up with the pump flange.
The pump suction line and the discharge line should have their own brackets or hangers. The weight of the pipeline is not allowed to be directly absorbed by the pump set to avoid crushing the pump.
2. The structure of the pump suction pipe and the pipe connection shall be installed according to the design requirements of the process conditions.
Ensure that the pressure and torque transmitted to the pump through the pipe do not exceed the permissible values.
At the same time, ensure that the flow rate of the pump inlet medium should be stable, avoiding the speed change caused by the pipe connection (such as elbows, valves, etc.).
The change in inlet flow rate has a significant impact on the pump head, NPSH and smooth running of the pump.
3. The installation height, length and pipe diameter of the suction pipe of the magnetic pump should meet the calculated value of NPSH;
And to ensure that the pump does not exceed its allowable NPSH when it is working.
4. When the suction pipe is installed above the pump body, the calculation of the suction pipe should ensure that the flow rate does not exceed 2m/s;
When the pipeline is excluded from the installation of the pump body, the calculation of the discharge pipeline shall ensure that the flow rate does not exceed 2.5 m/s;
When the delivered liquid approaches the boiling point, the flow rate should not exceed 0.8 m/s.
5. Only after the mortar has solidified and the pump’s motor anchor bolts have been tightened can the pipe be finally connected to the pump set.
6. The pipe that transports the heat medium should be fitted with an expansion ring so that the linear expansion of the pipe does not cause deviation.
7. Flushing and condensing piping should be installed to allow the pump to be flushed and condensed prior to disassembly and repair.
8. Thoroughly clean the pipeline before installing the pump to prevent solids from entering the pump and causing damage to the pump equipment.
9. Gasket mounting and gasket materials must be suitable for the process requirements.
