What is the reason of insufficient sealing degree of screw vacuum pump

Screw vacuum pump in the process of use, due to the environment, manual operation and other reasons, will cause some damage to the screw vacuum pump. Tell you why the seal is not tight enough in use:
1. Microbial mud is less polluted and full of yellowing void, which harms the compensation effect of yellowing on the sealing performance, increases the friction damage of rotating and rotating rings, and affects the sealing performance. Operators can be required to conduct quarterly removal of screw vacuum pump inspection
2, the addition of machine chemicals will cause slow erosion of the screw vacuum pump seal ring, will cause the seal invalid, so in the application to the operation, should first ask the screw vacuum pump businessmen applicable medium
What is the reason of insufficient sealing degree of screw vacuum pump
3. The comprehensive action of toxotoxins, microbial mud, calcium ions and related organic chemicals often contained in the working fluid corrodes the metal parts of the machine seal itself, which will harm the sealing performance of the screw vacuum pump seal
4. During the filling process of the upstream and downstream catalyst carriers, most of the soot is removed according to brushing and other processes. However, with the increase of operation time and the corrosion of material cyclone, new smoke and dust will inevitably be generated. The dust in the screw vacuum pump can easily enter the sealing position of the mechanical seal, causing damage and requiring regular maintenance and cleaning
5, screw vacuum pump working fluid (containing calcium ions) and carbon dioxide in the raw materials reflect the transformation of calcium bicarbonate damaged the machine seal. This is inevitable, but it can be maintained regularly and avoided as much as possible

How to deal with screw vacuum pump leakage

Hot push vacuum pump: screw vacuum pump, water ring vacuum pump, roots vacuum pump, oil-free vacuum pump, etc. First, what to do about the screw vacuum pump leakage
How to deal with screw vacuum pump leakage
During the use of the screw vacuum pump, air leakage will be affected. Many users think it is the quality of the equipment, so they will change to a new equipment. However, the cause of air leakage is not only the quality problem
1. Front and rear side covers with different centers
That is, the front and back cover of the screw vacuum pump has a large degree of coaxiality, the result is the same as the bearing skew
2. Temperature of liquid ring increases
As the liquid ring temperature increases, the saturated vapor pressure also increases, which reduces the vacuum of the screw vacuum pump, but this has no effect on the exhaust pressure
3, the seal is not tight
Tighten all connection bolts and packing gland of the screw vacuum pump, tightly wrap the pipe and the place where the meter is connected with other parts, or replace the gasket and packing. For screw vacuum pump air leakage, can also be coated with oil lime and other temporary remedial measures
4. Bearing skew
This phenomenon makes the impeller tilted in the screw vacuum pump pump body, for the single-acting pump, its axial clearance is not uniform, impeller rotation, there will be part of the side cover friction, abrasion side cover and impeller end face, so that the axial clearance increases
Compressed cavity gas through the increased gap, a large number of leakage into the suction cavity, so that the screw vacuum pump vacuum or exhaust pressure to reduce
At this time the screw vacuum pump bearing must be removed for repair, and then the correct installation
Screw vacuum pump is a kind of pump shell for synchronous high-speed reverse rotation and the suction and exhaust effect of the air pumping equipment, screw vacuum pump in the use of the process of air leakage need to be timely treatment, usually also need to be well maintained

Proper installation of water ring vacuum pump pipeline method

1. Choose a reasonable pipeline scheme
(1) the distance between the vacuum system outlet and the pump inlet is as short as possible;
(2) pipe turn the less the better;
(3) the inlet pipeline should be higher than the pump inlet center line, the outlet pipe should avoid causing greater resistance factors, such as the outlet pipe climb, right Angle turn, etc.
(4) with the import and export pipe diameter should be consistent with the product's import and export diameter, such as smaller vacuum system, import and export with pipe diameter can be small, but not less than 70% of the product's import and export diameter, and the export diameter should be greater than or equal to the diameter of the inlet pipe;
(5) pipeline corner should be smooth transition;
6 water ring vacuum pump inlet pipe of the road to install the valve, how to regulate water inflow and water inflow of how much has influence to the vacuum degree, adjust the water inflow by observing the vacuum table pointer to control the valve, the limit of SK - 0.8 vacuum can reach 0.087, in the working status, because the line is not completely sealed state, vacuum degree at around 0.06 can meet the job requirements.
2. Avoid falling into foreign matters when installing or maintaining pipelines.
3, pipe joints to add sealing gasket, there must be no leakage, leakage phenomenon.
4. Install a vacuum meter at the suction port of the vacuum system to grasp the change of vacuum.
When the vacuum degree reaches the limit, the valve installed on the pipe path of the suction port will produce a lot of noise, called cavitation sound, through the valve to adjust the vacuum degree, when the vacuum degree is high, pressure test blasting detector, open the valve to release an appropriate amount of gas, cavitation sound immediately disappear, the vacuum degree decreases and close the valve.
6. One of the important functions of circulating water is to cool the temperature generated when the vacuum pump works. When the circulating water temperature exceeds 40 ° c, the vacuum degree will decrease.

How does 2BV water ring vacuum pump resist cavitation

2BV water ring vacuum pump has the characteristics of simple structure, simple installation, oil-free, safe and reliable, etc. Due to its unique characteristics, it is widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields. It is well known that a piece of equipment will cavitate over time. How does a 2BV water ring vacuum pump resist cavitation? Let's talk about it in detail.
1. Reduce the temperature of working fluid of 2BV water ring vacuum pump to prevent cavitation.
2. By lowering the inlet temperature, the temperature of water circulating liquid can be lowered indirectly to prevent cavitation, and the drying speed of materials can also be improved to improve the utilization rate of equipment.
In installing a condenser inlet end, according to the calculated heat transfer area, containment inlet temperature condensation to condensable gas points corresponding to the temperature below the dew point pressure, condensate condensable gases, and pressure is reduced, thus the pressure gradient between the vacuum pump and the use point, raised to the dry material moisture vaporizing transfer speed, reduce the drying time, drying equipment and vacuum pump and condenser and without the contrast between can improve the drying speed of 40-50%, into the pump gas mixes with water vapor temperature after temperature lowering and not rise too much, reduce the heat transfer area of back-end water irrigation, so no, It can not only protect the equipment, improve the utilization rate of the equipment, but also protect the environment.
3. When cavitation occurs in the 2BV water ring vacuum pump, the main damage is the pitting corrosion of the impeller and pump shell surface caused by bubble rupture.
We can introduce atmospheric gases in the area of the compression, the specific method is: transition zone to drill a hole in the pump compression, and then the atmosphere with line into the area, when the bubble burst in the compression process, the introduction of air from the outside world can timely supplement by bubble burst "space", it can greatly reduce the damage to the pump cavitation and reducing the noise and vibration caused by cavitation.
4. It can be seen from the causes of cavitation of 2BV water ring vacuum pump that a working fluid with saturated vapor pressure can be replaced with a liquid with good fluidity and compatibility with the extracted gas, so as to reduce cavitation and improve vacuum degree. One disadvantage of this approach is the post-contamination treatment of the working fluid. So changing the working fluid is rarely used.
Mainly we pay more attention to these aspects when using, or cavitation drilling holes to harm the 2BV water ring vacuum pump, we can according to the above mentioned, do more work to resist erosion, to help it become more usable, hope that the above introduction can bring help to everyone's use.

Causes of automatic tripping of screw vacuum pump

Screw vacuum pump tripping condition is more serious, especially when used, very harmful to the equipment, internal components will have a certain degree of wear. If travel occurs, it is necessary to find the reason for maintenance to avoid recurrence and secondary damage to the equipment.

One, it is impurity
1. Vacuum pump exhaust suction foreign body or impurities, motor load, vacuum pump can be removed, check whether there is a fault inside.
2. Screw vacuum pump is forbidden for a long time
2. If the stop time of the screw vacuum pump is too long, the motor load will cause the temporary current to be too high. At this point, the inlet of the enclosed vacuum pump can be operated to add heat pump body.
Third, is the power supply
3. The vacuum pump motor is connected to the two-phase power supply. Three-phase power supply not enabled. Can turn on the three-phase power supply of vacuum pump. If you operate a trip or trip for about ten hours, you can adjust the overcurrent limit.
Motor load
When the screw vacuum pump is used, the motor load of the vacuum pump is too high. If the current set by the electric control box exceeds the current, the vacuum pump will trip and trip by itself. At this time, the vacuum pump normal phenomenon, can be adjusted the upper limit of current protection, to solve the phenomenon of tripping.
Regularly maintain screw vacuum pump cleaning and equipment maintenance. By testing the above three conditions, better maintenance equipment will improve the use of equipment. Otherwise, if travel occurs, it will not only affect the productivity of the enterprise, but also increase expenses.

A way of extending the life of a vacuum pump

Vacuum pumps are widely used in sewage treatment plants to transport water, wet sludge and flocculant liquid due to their characteristics of variable transport, strong self-suction ability, reversible, and can transport liquid containing solid particles.
Now in the market of pump product sort is more, relatively speaking, the import of pump product design is reasonable, the material is excellent, but the price is higher, the service aspect some do not reach the designated position, accessories for high pump products can be used in different industries and the promotion, play an important role and performance, show good performance and advantage in the industry, according to certain standards in the selection and the way to choose, to ensure the value and function in the practical use.
Domestic production of most imitation of imported products, product quality is uneven, in the selection of domestic production of products, in consideration of its cost performance, the selection of low speed, long lead, transmission parts of good material, rated long life of the product.
Pump selection should follow the principles of economy, rationality and reliability. If the design selection is not considered carefully, it will bring trouble to the use, management and maintenance in the future. Therefore, a reasonable and reliable pump product according to the actual needs of production can not only ensure the smooth production, but also reduce the repair cost. Speed selection of vacuum pump products in the selection of the pump products in accordance with a certain standard and way, can show good performance advantages and contributions in use. Must make the screw pump premature failure, and the high speed screw pump fixed rotor length is very short, easy to wear, thus shortening the service life of pump products. Through the deceleration mechanism or stepless speed regulating mechanism to reduce the speed, so that the speed of three hundred turn per minute below the more reasonable range, compared with high-speed operation of screw pump, the service life can be extended several times.
There is a linear relationship between the flow rate and the rotational speed of pump products. Compared with the screw pump with low rotational speed, although the pump with high rotational speed can increase the flow rate and the head, the power increases obviously. The high rotational speed accelerates the abrasion between the rotor and the stator.
In the wet sludge mixed with solid impurities will damage to the rubber stator of the pump products, so make sure debris into the cavity of the pump is not very important, a lot of sewage plant in front of the pump with a grinder, also some installation or mesh grille device, stop the debris into pump products, for grid should be timely get so as not to cause congestion.

Rubber ball action in water ring vacuum pump

Water ring vacuum pump, as its name implies, is a device that can produce vacuum. It has many internal parts, which can play different roles for the equipment and are very important in the equipment. Among them, what are the functions of its rubber ball?
1, in the water ring vacuum pump, the auxiliary exhaust valve is a special structure, the general use of rubber ball valve, its role is to eliminate the pump in the process of operation of excessive compression and insufficient compression phenomenon.
2, the two phenomena can cause excessive power consumption, because there is no direct exhaust valve, water ring vacuum pump and exhaust pressure is fixed, its compression ratio't decided to port of termination of the starting position of the location and vent, however, the two position is fixed, so don't meet the needs of the suction pressure changes.
3, in order to solve this problem, generally set the rubber ball valve at the bottom of the exhaust outlet, so that when it comes to an exhaust pressure pump cavity early, ball valve automatically opens, the gas discharge, eliminates the phenomenon of compression, generally in the design of water ring vacuum pump with low suction pressure to determine when the compression ratio, in order to determine the starting position of vent, this solves the phenomenon by the lack of compression.
It can be seen from the above that the rubber ball in the water ring vacuum pump is mainly used to eliminate the phenomenon of over-compression and under-compression. In other words, it can control the compression of the equipment and reduce the consumption of power, so as to protect the equipment.
