Guidance: During the actual operation, the port will produce dust during loading and unloading and transportation of bulk materials. Especially when loading and unloading coal and grain-prone materials that generate dust, the port will often become hazy and dusty. In the scene, many employees still feel breathing difficulties while wearing a mask at work. In the process of loading, unloading and trans- porting, there will be blanking and dumping dust, which will increase the severity of dust pollution. The port has become an important hub for mutual benefit and win-win cooperation among the countries of the world. It is also known as an important driving force for world economic growth. However, it has the same problem with the industrial enterprise workshop. It is dust pollution, and no company developed it in the early days. The negative pressure cleaning system does not have a good solution to the problem of dust in the port, which has also become a difficult problem for the relevant state departments and owners.
Main
Parameter:
(1)Lifetime:
Under certain loads, bearing in the number
or number of hours before pitting, known as bearing life. The life of rolling
bearings in revolutions (or speed of work under a certain number of hours)
definition: bearing within this life, in any of its bearing ring or a rolling
body occurred on the initial fatigue damage (peeling or defects). However,
whether in the laboratory or in actual use, can be clearly seen, the appearance
of the same bearing under the same working conditions, the actual life is not
the same. In addition to several different definitions of bearings
"life", one of the so-called "working life", it said the
actual life of a bearing can be reached in before damage is composed of wear,
damage is usually caused not by fatigue, but by abrasion, corrosion, damage and
other reasons. In order to determine the seal bearing life standard, the
bearing life and reliability Link. Because of differences in manufacturing precision,
uniformity of material, even the same material, the same batch of bearings of
the same size, under the same working conditions, the length of life is not the
same. If the statistical life of 1 units, is the longest life expectancy of 4
units, the shortest 0.1-0.2 units, the longest and the shortest life is 20-40
times of.90% bearing does not produce the number of revolutions of pitting, or
hour experience called rated life bearing.
(2)Dynamic load rating:
For the bearing capacity comparison of bearing
anti pitting, provisions of the rated life of a bearing one million , the
maximum load can withstand the basic dynamic load rating, C said. It is bearing
on the dynamic load rating of C under the action of the bearing one million
without the occurrence of pitting failure reliability for 90% C, the greater
the carrying capacity is higher. The basic rated dynamic load bearing 1. refers
to the pure radial load 2. thrust ball bearing is 3. pure axial load radial
thrust bearing is to produce pure radial displacement and radial component.
Category:
(1)Sleeve bearing:
Plain bearings, both inside and outside the
ring, there is no rolling body, usually made of wear-resistant materials, often
used in low speed, light load and filling lubricating oil and maintenance
difficult mechanical rotating parts.
(2) Spherical plain bearing
The sliding contact surface of the joint
bearing is spherical, which is mainly suitable for swinging motion, tilting
movement and rotary motion.
(3) Antifriction bearing
Rolling bearing according to different load
direction which can withstand or nominal contact angle for radial bearing and
thrust bearing. The radial contact bearing for the nominal contact angle of 0
radial bearings, angular contact radial bearing for the nominal contact angle
greater than 0 to 45. The radial bearing axial contact bearing for the nominal
contact angle for thrust bearing 90, angular contact thrust bearing for the
nominal contact angle is greater than 45 but less than 90 of the thrust
bearing.
(4) Deep groove ball bearing
Deep groove ball bearings are the most
representative. Compared to other types of bearings with the same size, this
kind of bearing friction coefficient is small, extreme high speed, simple
structure, low manufacturing cost, high precision, without frequent
maintenance, and large size range, form, bearing is a kind of the most widely
used. It mainly bear radial load, also can withstand the axial load. When the
only bear radial load, the contact angle is zero.
(5) Self-aligning ball bearing
Self-aligning ball bearing is two groove of
the inner ring and outer ring raceways between spherical and spherical ball
bearing assembly. Outer ring raceway curvature center and bearing center line,
so it has the same self-aligning ball bearing self-aligning function. In the
axial deflection shell, can be automatically adjusted that is not to increase
the burden bearing. The axial load of spherical roller bearings can bear radial
load and two directions. Self-aligning ball bearing radial load capacity, suitable
for heavy load, load impact. Inner diameter is tapered bore bearings can be
installed directly. Or use the sleeve, remove the tube installed in the
cylinder axis cage. Stamping steel cage, polyamide forming. Self-aligning ball
bearing is designed to withstand heavy load and impact load, precision
instruments, low noise motor, automobile, motorcycle, metallurgy, rolling mill,
mine, petroleum, paper, cement, sugar etc. Industry and general machinery, etc.
(6) Linear bearing
Linear bearing is divided into linear
bearing and linear bearing metal plastic. Metal linear bearing is a kind of
linear motion system with low cost of production, for unlimited travel and with
the use of cylindrical shaft. Because the ball bearing in point contact with
the shaft, so the load is small. The ball rotation to low friction resistance,
smooth movement so as to obtain high precision.

SINOVAC Watson Environmental Protection is a professional R&D and production vacuum cleaning system manufacturer. Our excellent technical team has conducted in-depth research on the process characteristics of bulk bulk materials, storage, extraction and transportation in ports, and launched dust treatment for port bulk loading and unloading docks. Solution - SINOVAC negative pressure cleaning system.
As for the loading and unloading of dust at the port, we have continued to carry out targeted design and renovation of the SINOVAC negative pressure cleaning system to improve the efficiency of port dust management. The characteristics are as follows:
First, high anti-corrosion: In order to deal with sea wind corrosion, we use high anti-corrosion measures from the material selection and surface treatment to extend the life of the equipment;
Second, the high degree of protection: for the ever-changing natural conditions of the port, the system and components meet the protection level above IP65;
Third, for combustible dust, carry out explosion-proof, anti-static design, explosion suppression system, explosion relief system, explosion-proof system, sprinkler system and other flexible configuration; all cleaning tools, cleaning pipelines, cleaning the host are using anti-static design;
Fourth, the design of large-scale storage ash tanks: there is a time when the blanking occurs at the port, and a large-capacity storage tank is especially necessary;
V. Large Suction Design: When blanking occurs or repairs, the large suction negative pressure cleaning system can help customers to quickly handle the stacking.
The SINOVAC technical team adopts an integrated design for port dust suppression solutions. The solution is flexible and variable. The negative pressure cleaning system has low overall operating costs, long life, and easy to move operations. In particular, the situation is complex, and the natural weather changes so well that it can respond well to the port dust pollution problem.
Since the establishment of SINOVAC Watson Environmental Protection, it has been focusing on the problem of dust management in the industrial sector. It has made a leap-forward innovation for dust removal equipment and launched a new negative pressure cleaning system (this also meets the requirements of related departments that companies need to use dust management. The use of negative pressure cleaning for transportation and removal regulations has solved the problems encountered by traditional and domestic baghouse dust removal equipment.
