How to choose paper machine oil
Because of papermaking machinery is to develop in the direction of large-scale, continuous, automatic, paper width and the speed of paper machine has been greatly improved, bearing the speed increase, more and more paper machine customer begin to choose lubricating oil in the system as a whole, rather than choose grease as bearing, gear lubrication of the medium in the system.
Therefore, the following factors must be taken into consideration when selecting paper oil:
(1)Hydrolysis stability: moisture is one of the biggest hazards in paper machine lubrication system, when a tiny crack on the surface of the bearing contact with water, the rate of bearing fatigue increases, cause pitting, early failure and abnormal downtime, caused huge losses.
High quality paper machine cycle lubricating oil must have excellent hydrolysis stability, to choose the right product and the first-class the system maintenance can help reduce the water enter the bearing seat, prevent premature failure of the bearing fatigue.
(2)Filter: it is time-consuming and expensive to replace the filter, and high replacement frequency is the signal that the oil filter is poor and the system maintenance is poor.
(3)Stable viscosity: because the bearing in the paper machine runs at a high temperature for a long time, it is important to ensure the stability of the oil in the transportation and operation. The key is composed of oil to have good oxidation stability and thermal stability, at the same time, centralized lubrication system design should have heating/cooling unit, maintain a relatively constant temperature system, to ensure that the oil viscosity.
(4)Deposition control ability: when the oil is aged, they will be decomposed by various mechanisms to form by-products, which will affect the performance of oil products. These by-products will increase the viscosity of the oil and plug the screen.Therefore, the oil formulation must have good sediment control ability.
The Measures To Solve The Dehydration Of Paper Machine
By pressing and drying methods in the process of paper making will break away of the moisture in the paper, in this process because of various reasons lead to dehydration, so what are the measures to solve paper machine dehydration bad?
High Quality Copy Paper A4 Paper Making Machine
A4 copy paper machine can use waste paper(such as waste books, news paper, used office paper, waste paper edge from printing factory ), virgin pulp as material to make high quality a4 copy paper, culture paper, writing paper and office paper. We supply the following cultural paper machine for paper maker.
Paper Machine Drying Section Paper Break
Wet paper into the dryer section, the dryness has reached more than 32%, with a certain intensity. But in the dry part there will be paper broken phenomenon. So what’s the reason that cause paper break in drying section?
40TPD Cultural Paper Making Project
This cultural paper machine Leizhan supplied used to produce Culture paper like printing paper, double offset paper, coating original paper, etc., there are many factors that affect the quality of paper, although the raw material determines the quality of the paper, good paper machine can make the finished paper quality better.
Disc Thickener for Paper Making
Disc thicken is mainly used for low concentration of slurry washe and thicken. This machine is different from the traditional vacuum disc filter, do not need to install at a higher floor and install leg pipe, can replace the traditional gravity rotary screen thickener, save energy consumption for paper maker.
