How to find a positive pressure tile machine
Alignment is to tile press impartially just in a predetermined position, so that vertical and horizontal centerline and basic tile press the centerline alignment. Therefore, we must look for the introduction of tile press center line or center point, namely to identify the positioning reference tile press and pressure-watt machine crossed. Positioning base tile press is generally in the specification, design or instructions on tile press has prescribed. If not specified, the base plane can tile press with geometric mapping method to find the center of the tile press. Tile press in place after use measuring tools and wire side of St. hammer, such as errors, can be used a pry bar pry tile press, minor adjustments, until the center line on the basis of positive so far.
Determined in accordance with the requirements of the position relationship between the clay tiles set in a variety of mechanical processes between each other, is to select one of the tile press as a reference, then press the tile press relations and in turn be determined centerline. Then centerline hanging wire frame can be set. Pull available round wire diameter 0.3 to 0.8 mm. When hung, should the line taut. Tension force is too small, the line sag and sway, affecting the installation accuracy. General tensioning wire tensile strength of 30-80%.

What are the structural characteristics of the sealing knife
Tile press sealing knife known as broken trowel. Its advantages are simple structure, manufacture, easy to assemble, little resistance to mud, it is widely used.
Vacuum sealed double tile press knife. When two stirring shafts are driven around the sealing tool rotational direction of the arrow, the knife cutting edge seal tooth will continually mud into pieces, shredded mud from the knife along the knife bevel gear teeth The gap extrusion.
The more the number of teeth, the pug is cut the more detailed, the better the vacuum treatment of mud. But cutter teeth too much mud into the vacuum chamber of the resistance is too large, not only increases the power consumption tile press, but also makes for a higher level of mud slowed. When a high-level speed for mud knife teeth can be more. Conversely, the knife teeth can be less.
Sealing knife knife teeth usually 4-8 teeth can be up to 12 teeth. When the upper level to screw extrusion, school arbor without vacuum box, then seal them into the overall knife. When the level of take-up shaft for single or stirring bar, very mixed meal by vacuum box, in order to facilitate disassembly, sealing knife made from outside.
Must ensure that the design and installation of the sealing knife, the tilt direction of the sealing knife tooth, and shall be consistent with the direction of the spiral where the agitator shaft seal reamer. Otherwise, seal cutting knife blade can be out of action, while the slope will lose teeth pug's "diversion Huan role pug Movement in the opposite direction, so that the pressure-watt machine is not working properly, or even cause parts of damage.
Knife to seal welded steel structure and as well, can also be made of cast iron.

Spiral reamer repair severe wear without the disadvantages
During use, the spiral reamer with mud cylinder liner gap to 10 mm, it should be welding. Some of this pressure watts Factory does not have enough knowledge gap spiral dumplings knife with large mud cylinder liner is still in use more than 30 mm, which is very economical.
Spiral reamer severe wear without repair, exactly what harm it will bring, the following main points.
Due to severe wear spiral reamer to gap mud cylinder liner plus pill mud mud reverse move back to serious, prone to mud-cylinder heat, reducing the production capacity of the pressure-watt machine.
Due to severe wear spiral reamer, reducing the effective work reamer extrusion area. Spiral reamer 30 mm radius wear calculation, JZ450 type tile press reamer effectively squeezing area decreased 15%, JZ400 type tile press decrease 30.8%, while the small-diameter tile press this effect is particularly serious. This is bound to greatly reduce the production of pressure-watt machine.
Because spiral reamer serious wear, outer mud lose extrusion pressure to form clay mud flow slows down around the central part of the mud flow speed, ie the central part of the cross section of mud mud faster than peripheral speed of mud, leading products appear spiral pattern.
Because spiral reamer severe wear, difficult to repair work can not be repaired even make reamer shortened life expectancy.
Spiral reamer group segments of life varies reamer. General subject material and transportation segment segment reamer reamer replacement once, press section reamer will have to replace twice.

Spiral reamer speed of the impact on the tile press
Different specifications, form of tile press, its spiral reamer speed varies, there are a dozen turn, two dozen turn, turn around until fifty. When a certain range of speed is too high reamer, tile press, although the efficiency can be improved, but at the same time it increases the load and power consumption of tile press, prompting a greater mechanical wear. Under the same conditions, a larger diameter smaller than the diameter of reamer reamer peripheral linear speed of the outer edge of a large, so large diameter reamer should be slower than the rotational speed of the small-diameter reamer.
However, the yield tile press does not always improve the anti-reamer and increase speed. When Reamer speed to a certain extent, an increase in yield tile press was limited, or even decline. Therefore, there must be an optimum speed in which the title. At the optimum speed, output pressure tile machine speed increases and rises; more than the optimum speed, yield increase or decrease quantity is small, the power consumption increases, but the parts wear and tear.
Best speed is obtained by experiment. JZ400 type tile press production of ordinary brick, once in a spiral reamer speed of 36-75 rev / min within the scope of the test, the results of 53 rev / sharing best. Of course, with different factors such as the nature of the mud, the best speed is not the same.
The current production, peripheral velocity spiral reamer generally use 60-65 m / min is suitable.
When moderate mud plastic, reamers can take the high speed value, and vice versa should be low,
When the mud molding moisture content is low, reamers speed should get lower, and vice versa should select a higher value,
When the large-diameter spiral reamer, the speed should be lower, and vice versa should select a higher value,
When a large enclosed cylinder length, speed spiral reamer should select a lower value, whereas some high speed optional too.

Structure and characteristics of the mud which the cylinder
Mud is a cylinder with a flange at both ends of a cylindrical part. Back through the ear and the front axle bolts and tank are connected by the tip of the head flange bolts use. Large multi-use clay tile press cylinder vertical split, and removed the bolts on the flange, two steps can be separated from the mud tank, bring convenience to spiral reamer disassembly and repair.
Production capacity of tile press, the size of the subject to the constraints of the mud tank, the other conditions being the same, the larger the diameter of the mud tank, the higher the production capacity. In addition, the shape of the mud tank tile press production and power consumption is also affected. Mud cylinder shape our current tile press, basically there are two kinds of cylindrical and conical.
Painting conical mud mud into the side of the cylinder diameter is greater than the output, it makes the pug running resistance increases, the yield decreases. In addition, when the forward mud due to greater resistance, some mud will return back along the spiral reamer mud and mud cylinder liner clearance. Therefore, according to practical experience, has been replaced by a cylindrical-conical mud mud tank cylinder, so yield tile press is greatly increased. The new tile press using cylindrical clay cylinder, mud pressure is close by selling variable pitch spiral reamer is completed. The advantage is that at which the mud is moved forward, small power consumption, high production capacity.
Because Lake cylinder head and the transition section is subject to the bin and spiral reamer is part of a long cylinder rotating in the mud, mud rotary extrusion in this chamber, mud tank suffered great resistance, wear it great. To prevent rapid wear of the mud tank, the mud cylinder walls lining with a removable metal bushing, and in order to make possible the machine pug mouth moves along together to prevent rotation when rotating spiral reamer, while the liner system as with longitudinal grooves. When the mud to fill in these trenches, they have a greater resistance to prevent the mud in the mud rotary cylinder wall, thus increasing the pug forward speed.
Some tile press spiral grooves in the mud cylinder liner, its helix spiral reamer opposite direction. Practice has proved that this structure to improve the quality of clay, lower operating resistance have good results.
