5 spiral twist a dragon and a bushing wear resistance of
Helical twist to improve the wear resistance of a dragon and a bush, right to maintain and improve the extrusion
Machine efficiency is very important, the use of serious wear and tear of the helical twisting dragons and bushings, squeeze
Squeeze out the machine will significantly decrease the efficiency because the helical twisting dragons and bushing wear
After increasing the gap between the two, so back around the produce, not only lowering
Low extrusion efficiency, also caused mud-cylinder heat affect the product quality.
6 head
Head's main task is to collect materials, and in which squeezed
After the dense, uniform supply of machine mouth. Nose shape and size should be the original
Metal Forming characteristics and needs of molding pressure matched in order to achieve the best into the
Type effects, improve the efficiency of extrusion machine.
7 Spindle Speed
Spindle speed is the extrusion molding machine in an important parameter, high-pressure
Molding Choose low-speed, high-speed low-pressure molding choices; low-speed molding
Can reduce the mud flow in the pulse inside the nose will help to improve product quality;
In other conditions permit, the general promotion of large low-speed pitch.
Understanding of the spindle speed, and many manufacturers exist errors
That is proportional to rotational speed and output, in order to increase the production of infinite speed,
This did not happen, not only did not increase production, but also to increased wear and tear, but
Reduces the efficiency of extrusion. Without breaking the mud pre-equilibrium transport and extrusion
To mention, the modest increases in speed, it helps improve the efficiency of extrusion.

Quinolones, a serial of synthetic anti-bacterial medicine, have the advantages of broad anti-bacterial spectrum, long duration, quick oral absorption, high concentration in tissues, simple structures, convenient administration, none cross-drug resistance with other drugs, relatively low side effects, being produced synthetically, high ratio of effectiveness and price, etc. Therefore, they have been widely used in clinical cases and paid more and more attention. Since nalidixic acid, the first drug of this sort, was developed, this sort of drugs have been developed rapidly and becomes a focal point of anti-bacterial researches. This paper focuses on the introduction of the history, clinical use, side effects, proper selection and application, developmental trend, and developmental prospect of quinolones, to give readers a general understanding about their development.

A higher supply capacity
Right vacuum extruder, because the raw materials needed to enter the vacuum chamber
Self-sealing, so superior are designed uniaxial or biaxial screw feeding,
And raw materials into the vacuum chamber before the compression of raw materials in order to achieve sealing role, indeed
Paul vacuum chamber of the vacuum, because the set compression seal segment, the higher the
Supply capacity can not be like a single-stage extruder, as do any of feeding, in order to
This must be designed for superior supply capacity to meet the junior high
The need for forming the main factors to consider are: the length of the compression seal and the cone
Degrees, higher speed, higher screw diameter, lead, and axial length.
As long as to achieve the desired sealing effect on the line, unreasonably increase the resistance,
Not only increase the power consumption, but also to increased wear and tear. A number of manufacturers from the domestic system of
Devices made of point of view, regardless of where the equipment was sold, and regardless of what the raw materials, the
Shu-size-fits-mentioned parameters, which of them would cause great waste; for
Plasticity index higher, raw materials, better sealing of raw materials, should be sealed at
"Burden reduction", Hefei Leroy Machinery Company set up two sets of parameters here, as far as pushing
Counted in high-ripening effect of raw material of plastic, or a better use of raw materials, can squeeze
A machine to reduce the total load of 2% to 3% (compact type).
2 lower spiral lead
Lower extrusion screw lead is an important parameter, which is the original
Material in the cylinder in the transmission, compression molding can smooth the key element of the
Affect the efficiency of an important factor in extruder.
There are other lower helical pitch (lead), variable pitch, diameter, adjustable, etc.
A single form or a combination of pitch and composition using the form of how crowded
The efficiency of a machine a very great impact. From raw materials transportation, compression, molding process
Point of view, pressure to gradually increase in focus on the nose when the greatest pressure. Theoretically
Talk about this process should be designed in descending pitch to pitch, or the
In the bore on the design of descending to Reducing, more in line with the pressure distribution
And raw materials during compression. So that the whole process smooth, all in one, to mention
High extrusion efficiency. As for the present situation by conveying compressed into the molding process
In the situation of small to large pitch, the authors suspect that there is reduced efficiency,
And in forming large pitch-side option, so that the rotating weeks intensified to reduce
The stability of the molding.
The range of choices pitch cylinder diameter and raw materials according to the characteristics
OK, to overcome the frictional resistance and resistance to mud flow case of reflux,
As far as possible out of the election so as to enhance the efficiency of large pitch.
Spiral lead a reasonable choice, to improve the efficiency extruder is crucial,
Depends primarily on material characteristics and needs of the molding pressure. A factory JZR45 /
40 extrusion machinery and 132 kW motors, current production to reach 330 ~
360A, other conditions remain unchanged, improved by spiral lead, the current reduced to
220 ~ 250A, can be seen on the lead screw extruder efficiency impact is enormous.
3 Day Spiral
Forming terminal helix, which we call the first section of spiral, generally use the two-lane
Spiral, mainly to increase the stability of molding. The first section of screw-lead and production side
Type the impact of the efficiency of the extruder can not be neglected. As the screw is inserted in the main
Into a vice screw, so that the original mud flow blocked and traffic could be diverted, mud flows Road changes
Too narrow and not dealt with properly here extruder load will increase, the impact extrusion
Efficiency.
As the vice screw inserted to reduce the mud flow of Tao half, and then
Coupled with spiral thickness, making the channel resistance to surge here. In order to understand
Must mudslides blocked the issue here, it is recommended to take two steps: ① The first section of
Helical pitch apart from the thickness of the inserted outside the Vice-helix, and then compared with sub-section spiral
Pitch to increase 5%, with the main vice screw pitch helical pitch fairly; ② in the first section of
Spiral Lord, Vice-leaf compared to external than internal forward 5% ~ 8%. The first section of spiral
Design and manufacture of inappropriate and often neglected, practice that, according to the above method
Processing, will generally out of production increased by 10% and the current decreased by 10%.
4 spiral seal length
Seal was also affect the length of the screw extruder efficiency of a factor.
Spiral seal is too long, increase the resistance of mud flow and to increase the transmission distance, making
Exercise in futility; spiral seal is too short, can not be achieved effectively prevent soil material back,
Extruder can not work effectively in a state, the efficiency of the same will be reduced.
Extruder to meet the case of a normal working state should try to shrink
The short length of spiral seal. According to the specific length of the molding pressure, lead, cylinder
Trail and the material properties determined. The use of a unit of production JZR45/40 clay
Hollow brick, Hough-cylinder length of 665 mm, replace the cylinder into a 450 Hough
After the 8% increase in production, the current decreased by 10%.

Level 1 supply capacity
For vacuum extruder, due to the raw materials into the vacuum chamber sealing, so in their superiors are uniaxial design for double-axis or spiral, and into the vacuum chamber in raw material, in order to achieve before compression, ensure the vacuum sealing function of indoor vacuum, because the compression Settings, superior seal supply capacity is not like the single extruders that any material feeding, must design the reasonable superior supply capacity, in order to adapt to the lower efficiency of molding, main consideration to the length of the seals are: compression speed, superior and taper, higher spiral diameter, lead and axial length.
Only attain sealing effect, not only increased resistance, reasonably increased power consumption, but also to wear. Some domestic manufacturers from the perspective of the equipment, equipment sold where, no matter what material, the above-mentioned parameter waking, which is a waste; For plastic index is higher, the raw materials, should better sealing seal "in the burden", hefei LeHua machinery company is set up in here, according to the calculated parameters of two sets of plastic or raw materials in aged when good materials used, can make the extruder total load reduces 2% ~ 3% (compact).

2 subordinates lead screw
Lower lead screw extrusion molding is the important parameters, it is the raw material in the cylinder of conveying, compression, forming can smooth the key factors of influence, is the important factor efficiency extruder. Such collective (lower spiral has lead), pitch, etc, bianjing and other single form or, using combined form and how to pitch extruder efficiency is very big. From the raw material conveying, compression, molding process, gradually increased pressure, the pressure when focusing on helicopter. Theoretically this process should be designed from the collective, or variable in the design of large diameter cylinder from small diameter, variable to conform to pressure distribution
And raw material compressing process. So that the entire process, smooth, distribute to improve efficiency of extrusion. For the present by conveying compression molding process to pitch from the status, the author thinks that have reduced efficiency, and the forming of the suspected that the big collective choice to rotate strengthened, week reduced molding stability.
According to the scope of the collective choice of raw material and cylinder diameters to determine the characteristics, can overcome frictional resistance and mud flow reflux, under the situation of resistance to choose big collective so as to improve the efficiency of extrusion. Rational choice, to improve the lead screw extruder efficiency, mainly depends on the crucial material characteristics and needs of the molding pressure. A factory JZR45/40 extruder complete 132 kW electrical current to 330, production and other conditions 360A ~, the lead screw improvement, the current to 220-250A and visible to lead screw extruder efficiency is very large.
3 first quarter spiral
The spiral shape, we call the first quarter, generally USES double helix shape, main is to increase the spiral stability. First quarter lead screw extruder production mode and the influence of efficiency should not be ignored. Due to the Lord in a spiral into the mud, vice spiral flow, and blocked way become narrow, mud flow deal with this will make the extruder load increases, impact extrusion
Efficiency.
Because of this, vice spiral into mud flow, plus half way reduce thickness of the spiral, make this channel resistance. In order to solve the problem in this mud flow, we suggest to take two measures: (1) the first quarter in consideration of inserting screw pitch again, vice spiral thickness than times, increase 5% section spiral pitch with the deputy helical pitch spiral pitch, 2 the first quarter spiral leaf external, internal compared than forwards 5% ~ 8%. The first section spiral design and production, often overlooked, practice proves that the method of handling, according to general can make the extrusion production increase 10%, current by 10%.
4 helical sealing length
Helical sealing length is also affect the efficiency of extruder, a factor. Helical seal is too long, increase mud flow conveying distance and make more likeable, resistance, Helical seal, can effectively prevent mud materials, extruder, not at work efficiency will also reduce. In normal working condition of the extruder should try to shorten the length of helical seal. According to the specific length molding pressure, lead, cylinder diamethe and material characteristics. A unit used JZR45/40 production of clay
Hollow bricks, cylinder length for 665 mm, change into 450 hough cylinder, yields 8%, current by 10%.

A higher supply capacity
Right vacuum extruder, because the raw materials needed to enter the vacuum chamber
Self-sealing, so superior are designed uniaxial or biaxial screw feeding,
And raw materials into the vacuum chamber before the compression of raw materials in order to achieve sealing role, indeed
Paul vacuum chamber of the vacuum, because the set compression seal segment, the higher the

This must be designed for superior supply capacity to meet the junior high
The need for forming the main factors to consider are: the length of the compression seal and the cone
Degrees, higher speed, higher screw diameter, lead, and axial length.
As long as to achieve the desired sealing effect on the line, unreasonably increase the resistance,
Not only increase the power consumption, but also to increased wear and tear. A number of manufacturers from the domestic system of
