What ways does the Paper Machine save energy?

When seeking to maximize the energy performance of a paper machine drive, it is not enough simply to select the most energy efficient components. Correct dimensioning is critical, and complex interactions between components mean that the system as a whole must be carefully designed. Attention must also be paid to the control software, which plays a key role in availability and can therefore have a major impact on overall energy efficiency.

Toilet paper machine is a kind of paper processing machinery for the production of toilet paper; it is the essential tools of the toilet paper manufacturers. In the society of pursuing energy saving and environmental friendly development, enhancing the energy efficiency of equipment is the best choice for toilet paper machine suppliers and buyers.

A large toilet paper machine drive can consume up to 30 MW of power. With production running continuously for very long periods, even a relatively small incremental improvement in energy effi­ciency can produce considerable savings over the long term. Variable speed drives can produce remarkable increases in energy efficiency in certain applications by adjusting the speed of the motor to match the demands of the process.

Another way to save energy for toilet paper machine is regeneration. In applica­tions with successive acceleration and deceleration cycles, regenerative drives produce electricity during the braking phases and feed it back to the network. If the machine can be liquid cooled, which can dramatically reduce the energy consumed in air condition­ing and cooling electrical rooms. Liquid cooling can decrease energy losses to the air within the electrical room by as much as 98 %. Other advantages of liquid cool­ing include a higher power density and compact drive cabinets, and higher pro­tection class enclosures offer increased options

In order to optimize the energy efficiency of a toilet paper machine drive it is important to look at the system as a whole. This is because efforts to boost the efficiency of a single component in isolation may end up causing increased losses elsewhere.

It is therefore crucial to understand how the type of power supply, VSD switching frequency and output voltage, and the motor design, affect total system effi­ciency. Achieving optimum energy effi­ciency involves much more than simply comparing the catalog values.

Five Usage Tips and Tricks for Cement Pipe Machine

Plenty of pipe making machines have different category, like PVC pipe machine and cement pipe machine. And according to the materials, they can be sorted to high frequency weld pipe machine and stainless steel pipe machine. Today I want to share you something about the usage of cement pipe machine.

It is unavoidable that during the manufacturing process there is certain wear and tear for the cement pipe machine, but how to minimize the wear and tear and improve the machine’s durability? When using cement pipe machine, you should follow the tips below:

1.      Choose the appropriate type of cement. In general, the cement of high strength and long durability is the better choice. And as the using condition of cement pipe machine changes, some cement of unusual properties should be chosen such as sulfate resistant cement and fire-proof cement.

2.      Appropriately control the water cement ratio and cement content of the machine. The water cement ratio is the main factor in determining the concrete density and its durableness, so you should strictly control the water cement ratio. Likewise, ensure the cement content can achieve the same effect.

3.      Select and use technically qualified sand and high quality stone aggregate, which is the fundamental condition that assures the durability of cement pipe machine.

4.      Mix air entraining agent or water reducing agent. The using of air entraining agent can help to improve the anti-permeability and freezing resistance, and to some degree, have a role in saving water.

5.      Refine the operation method of cement pipe machine. In the construction of concrete, the cement pipe machine should stir evenly and vibrate tightly; moreover, the machine should be well maintained so as to ensure its construction quality.

Cement pipe machine has occupied an important position in the present construction industry due to its wide application. And since the whole world is in pursuit of environmental protection and energy saving, cement pipe machine has been paid more and more attention for its good performance in both the two sides.

Work Noise – Signal of Lack of Maintenance for the Pipe Machine

Sometimes in the working process of the pipe machine, the machine will produce some noise, not as it is under normal operation. In facing of this situation, some people will ignore it and think it normal. Actually, it is the signal that your pipe machine needs maintenance.

So what causes the pipe machine to produce noise? The following reasons may account for it:

1.      The coupling is not installed in the same center and it needs reinstallation. The deviation should not over 0.1 mm.

2.      There are some air slipped in from the oil suction pipe or oil seal, you need to replace the sealing element and polish the junction surface.

3.      The oil filter pump of the oil inlet is partly blocked, and you have to clean the oil filter.

4.      The machine is low on oil; refill the oil tank to the oil line.

5.      The stator and blades are severely worn down; update new parts.

Most of the noise is caused by inadequate maintenance, so when you are using a pipe machine, please don’t forget to its daily maintenance. To be specific, there are some useful advices for you.

Firstly, regularly check and inspect the lubricating point and fastener. And choose the suitable lubricating oil.

Secondly, frequently wash the air filter, oil filter, cooler and oil tank so as to keep the oil passage smooth.

Thirdly, the hydraulic oil should be controlled to a rang of 30 to 55℃. When the oil temperature is lower than 15 or above 60℃, starting up the machine id forbidden. And the heater or cooler can be used to regulate the oil temperature. 

Lastly, after the run-in period is over, mandatory maintenance should be taken to the pipe machine, and meanwhile, renewal the hydraulic oil. Generally, the hydraulic oil needs to be replaced every 6 months, and when doing this, you should thoroughly wash the oil tank and oil pipe. The deterioration of hydraulic oil may lead to the increase of noise, as well as the shorten life span of oil pump, hydro-cylinder, reversing valve, etc. or even worse, paralyze the whole working system.

Take you learn about 5 types of Wire Mesh Machine

Wire mesh welding machine is a common seeing machine can product different wire diameters and meshes according to various kinds of welding requirements with high quality.

The following wire mesh machines are classified to different types:

1.      Mine support network welding machine.

This model is used to produce coal mine supporting mesh, the welded diameter could be 4mm – 7mm, and mesh size could be 2m – 6m. This machine adopts synchronous control technique, sub-control welding and welding time control, and by PLC digital programming systems the input panel could be either touch screen or key press, the operation is more intelligent and rational.

2.      Heavy duty steel mesh welding machine.

This classification is mainly used for pouring concrete with steel mesh in bridges, water conservancy, highway, national key projects, the welded mesh is up to 2.5 meters in width and 12 m in length, welding diameter from 6mm to 12mm. Adopting synchronous control technology, and controlled by IPC management system, the operation become more intelligent and user-friendly.

3.      CNC mesh fence row welder.

This kind of mesh is the most advanced network welding equipment, the biggest advantage is that the wire diameter is adjustable, entering aperture of the weft into the computer, and it will be able to reach the pitch welded mesh as you want.

4.      Anti-theft network welding machine.

The device uses the motor as a power source, which is the updated version of using compressed air as a power source. It can work normally under a temperature below 0 ° C, and due to the cancellation of some quick-wear parts such as cylinder, and valve, the failure is just 1% of gas powered grid welder. Intelligent control of the equipment, welding time and sub-control welding current by digital Speaking of the man-machine interface, high precision, stable performance, solid solder joint and no burn marks are all the advantages of this equipment. It is equipped with high welding speed, and is easy to operate.
