Management and maintenance of papermaking machinery? The management of papermaking machinery and equipment——Prevention-based The papermaking industry is determined by its process. The equipment cluster and monomer are relatively large, continuous and highly automated. Therefore, once the damage often has a huge impact, in order to avoid as much as possible the loss caused by the emergence of major and uncontrollable problems, the mechanism design is constantly changing and improving, such as regular inspections and spot inspections, which are largely controlled. On this basis, advanced equipment detection methods have played an important role ...

How is the pressure screen maintained? During the application of the pressure sieve, due to factors such as process water, calcium and magnesium hardness, pH value, electrical conductivity, total alkalinity, temperature and other factors, scaling has occurred, which causes the following hazards: 1. Increase the number of unplanned shutdowns and cause production interruptions , Affecting the production efficiency of the device. Shutdown and cleaning, increase maintenance costs and additional labor load; 2. cause paper disease, affect product quality; 3. increase the consumption of chemicals and pollution load; 4. cause production accidents, reduce ...

The pressure screen motor needs to be installed vertically. The installation of the pressure screen uses the lifting ears and holes on the base to lift the pressure screen from the supporting plate as a whole, and place it on the foundation. The screen body must be horizontal during installation to make the screen body stable and anchor bolts affected The force should be uniform, and the liquid should be drained when the machine is emptied, and all anchor bolts should be tightened. The motor is mounted vertically on the motor base plate, which is placed on the motor slide rail. Put the V-belt pulley on the motor shaft and make it at the same level as the V-belt pulley of the screen body.

The sieve slurry of the pressure sieve is not blocked. 1. The sieving efficiency of the pressure sieve is high: due to the high pressure of the slurry entering the sieve along the tangent line, and the centrifugal force, the fiber and coarse impurities have been carried out before the slurry enters the sieve drum. Separation. Qualified fibers quickly pass through the sieve drum by the pressure difference between the inlet and outlet. 2. The screen drum has a long service life: after the pulp enters the pressure screen, the heavy impurities of the pulp have been separated by centrifugation, so the impact and wear of the impurities on the rotor and the screen drum are reduced. Extend the life of the screen drum. 3 ...

Recent developments and future trends of papermaking machinery Our company (www.lfzzjx.com) is a manufacturer of papermaking machinery. Let us talk about the development status and future development trends of papermaking machinery in recent years. To some extent, the phenomenon of overcapacity has occurred, especially under the influence of the current international financial crisis, and the industry has encountered greater difficulties. Facts show that the extensive development approach has come to an end, and the realization of the strategic transformation of the paper industry is the industry's development to the current stage ...

Design of the upflow structure of the pressure sieve The pressure screen is a new type of recycled paper pulp screening equipment. This equipment is designed as an upflow structure for the characteristics of impurities in recycled pulp. It can be widely used in rough screening of various waste paper pulp, The coarse screen and the pulp screening before the paper machine have unparalleled good performance and reliability. It is a new generation of various domestic pressure screens for the regeneration pulp processing. The pressure screen adopts the upflow structure design of bottom slurry feeding, bottom heavy slag discharge and top light slag discharge, which effectively solves ...

What are the piping configurations of the pressure screen? Pipeline configuration of pressure screen. 1. Pulp inlet pipe: Install a valve, and set a bypass clear water pipe on the pulp inlet pipe for washing the sieve drum and casing. The feed pressure is 0.1-0.25Mpa. 2. Pulp outlet pipe: Install the valve, the diameter of the pulp outlet pipe is configured according to the diameter of the pulp outlet, and the pressure difference between the pulp inlet and the pulp outlet is 0.01-0.04Mpa. 3. Tail tube: Install the valve. The diameter of the tail tube is configured according to the diameter of the tail tube.

With the development of the enterprise, the company has introduced various advanced equipment and matched modern advanced management technology, so that its comprehensive production, service and production capabilities have entered the forefront of its peers. The following is the principle of using the pressure screen: The pressure screen is an advanced pulp screening equipment, which can be used for pulp screening of the pulping system and for pulp selection before the paper machine. The outer rotor internal flow pressure screen uses the pressure difference between the inside and outside of the sieve drum and the positive pressure of the rotor head as the screening power, using ...

Structure and performance of pressure sieve Pressure sieve 1, sieve drum: sieve drum with fine screen sieve width H0.15mm, grooved on 8mm thick steel plate using water jet cutting technology, forming excellent round holes and burr-free notches Stress and groove cracks are generated like mechanical washing and polishing of grooves. And can provide a hard degree network process to improve anti-wear performance. 2. Rotor rotor: 3-4 rotors are installed on the semi-finished rotor, and the balance is strictly adjusted after assembly, so that the rotor does not generate vibration during high-speed rotation. The rotor is mounted on ...

Papermaking equipment preparation equipment Papermaking machinery includes raw material preparation, pulping, papermaking, until it is made into rolls or sheet products, and paper and cardboard processing machinery. It is equipment for pretreatment and processing of papermaking raw materials before cooking or refining according to the requirements of the cooking or refining process. It is divided into non-wood fiber preparation equipment and wood fiber preparation equipment. The former includes grass cutters, reed cutters, and sugarcane pulp removers, while the latter includes peelers and chippers. The chipper is to cut the logs required for the production of wood pulp into a certain ...

Lubricating characteristics of papermaking machinery The working environment of papermaking machinery is humid and high temperature, and some equipment is also accompanied by impact load. Therefore, the choice of lubricants mainly considers its anti-emulsification, water resistance, thermal oxidation stability and load resistance. . The lubrication points on paper machines are in principle closed. Each bearing of the wet section of the papermaking machinery, that is, the headbox to the press section, is sealed with a bearing housing to prevent cross-contamination caused by water immersion and grease overflow. The dry section of the paper machine is due to the high temperature during the operation ...

The working principle and performance of the pressure sieve The pressure sieve adopts an up-flow structure design with bottom slurry feeding, bottom heavy slag discharge and top light slag discharge, which effectively solves the above problems. The light impurities and the air in the slurry naturally rise to the top slagging outlet for discharge, and the heavy impurities can settle to the bottom for discharge as soon as they enter the body. In this way, on the one hand, the residence time of impurities in the sieve area is effectively shortened, the possibility of impurity circulation is reduced, and the screening efficiency is improved; on the other hand, the rotor and the sieve drum are prevented from being damaged by heavy impurities, and the equipment is extended ...
