Correctly grasp the installation and use of the conveyor

An accurate installation and maintenance to ensure that the specifications of the same scraper chain , rolling at flexible operation .
To ensure flatness of the inner wall of the cabinet , will not allow the interface flange and the plastic chain conveyor rail up and down the wrong move , should ensure that the coupling is smooth and

no stairs . Also the interface flange should be straight , and the verticality of the housing should not exceed 1mm, to ensure that the phenomenon will not produce scratching

scraper chain is running, there is conducive to the normal

Operation , to Power Roller Conveyor reduce wear and power consumption.
Ensure head , tail wheel center line level degree promised error within 6mm, and the head, tail wheel and necessary to support rail , and the head , the tail wheel levelness

required school level.
Ascertain the direction of the scraper chain , do not hold against . Scraper chain to ensure proper tightness should not be too tight or too loose. Adjust the tail unit , to

ensure that not less than 50% utilization of the whole of the trip . Electric motor output shaft , gearbox output shaft and the head of the shaft should be parallel to the

conveyor ,

In response to the size of the chain and sprocket two axial offset to within 2mm.
Second, the gap between the blade and adjust the appropriate backplane slot machine This is a relatively important issue , which affects the efficiency of life and

transportation equipment . Clearly, the gap is too small , clinker easily stuck between the blade and the slot machine , slot machine floor scraper or cause damage , even when

severe hair

Health scission accident. Gap is too large , decrease the transmission efficiency . The size of the gap depends on the particle size of the clinker is generally determined by

the following formula :
A> A represents a blade clearance with the bottom of the groove panel D / 2 +5 formula (mm); clinker D represents a maximum particle size (mm).
After calcining kiln clinker cooler through after cooling , hammer crusher after a maximum particle size of 25mm or so, control the gap scraper plate in the bottom slot with

more than 17.5mm , which can reduce the bottom slot plate and scraper wear and prolong its life.
Third, accurate , fair and timely maintenance efforts to strengthen the inspection , examination revealed scraper chain without deformation or rupture , pin the pin on the

falling, should be repaired or replaced.
When the scraper chain loose should be timely adjusted so that the scraper chain often work under proper tension situation , find the topic , in time, to take preventive

measures .
Fourth, the fair design and excellent manufacturing quality carrying member scraper is made ​​of 16Mn steel, welded directly perpendicular to the chain .
Scraper chain is pulling member which is designed for dual- plate chain , after the two steel plates welded into a chain of metal forming rod , then pinned together . Red Star

which is characterized by the use of reliable , manufacturing simple and cheap. In operation, the scraper chain to overcome a lot of friction , bearing

By a great dynamic load and static load , the scraper chain in the manufacturing and welding to be heat treated so as to have high strength , toughness and wear resistance.
Chain plate selection 45Mn2 quenched in the material , hardness HRC62 , the longest life . Pin 45 steel or 40Cr quenched , its quenching hardness HRC38-43.
Strictly control the gap scraper and bottom of the slot machine . Found wandering, timely inspection and timely adjustments. After taking relevant measures , buried scraper

conveyor greatly extended service life , overhaul period of four months from the original extended to 2.5 years , not only reduces the maintenance workload and

In favor of lower production costs , improve their market competitiveness.

Construction machinery from manufacturing to innovation

China 's construction machinery industry did not rely on the garment industry to seek large-scale OEM production of their own development , but also did not rely on the

automotive industry in gravity skatewheel conveyor general as a joint venture to enhance their own strength , but rather out of a technology introduction, digestion, absorption and innovation on the road ,

and gradually mastered its own

Initiative , which for other industries also have a strong reference.
From manufacturing to "wisdom" made
Investment Advisor in the machinery industry researcher Duan Jiaxuan that the development of China's Pipe conveyor construction machinery from the historical point of view , totally dependent

on foreign capital is no future , even in the strength of the gradual growth of today, although there is a large gap between the foreign advanced technology , but also cut Do

not be so anxious to achieve

OEM technology upgrading and took the road to better have strong strength in the time base through mergers and acquisitions , learning and innovation , etc., to absorb

technology, adhere to the road of self-development .
Innovation into the industry rapid development momentum

After 20 years of development, China 's construction machinery industry strength has improved significantly , but in the advanced foreign technology and there is a large gap. If

you embark on the road of OEM production , although you can change in the short term more advanced foreign technology, but the loss of self- brand development .

The lack of independent brands , will be tightly nailed to the low end of the value chain , always walk on the road in low value-added .
Investment Advisor in the Research Director Zhang Yan Lin said that at present , multinational companies to enter the Chinese way of being quietly changed, from the past use of

China's low manufacturing costs , preferential policies to enhance competitiveness factors , leading to the acquisition of a number of Chinese enterprises, OEM cross

Country 's products , and use Chinese company's marketing network and manufacturing capabilities to become a part of its global industrial chain .
Gradually mastered their own initiative
If Chinese enterprises in order to seek quick access to advanced technology and become part of transnational global industrial chain practices often faced with great risk,

although the short term production may increase rapidly, but in key areas , high value-added parts will always be foreign controlled, and

The right to sell and purchase the right one was firmly in control , making it convenient for a profit transfer , in the process , but also Chinese enterprises can only act as a

manufacturing plant 's role only.

Screw conveyor which is mainly used in industry

Go head and tail bearing housing , the hanging bearing sliding bearings , no dust seals , bearings generally use powder metallurgy , transportation of cement used blankets

bearing, shaft and screw spiral conveyor shaft with hanging sliders connections, remove screws, without moving drive means for hanging shaft removal

horizontal or gravity conveyor inclined conveying powder, granular and small bulk materials such as coal, ash, slag , cement, grain etc. , the material temperature is less than 200 ℃. Screw

machine discomfort

To transport perishable , viscous , easy caking materials

Conveyor injury accident preventive measures

Belt running speed, roller and more, a little careless, often easy to cause injury accident. To prevent injury accident should take the following measures:
1. Transmission part of the belt conveyor nose, tail drum, fluid couplings, etc. must be installed or protective guard railing. Need to cross the bridge should be installed in

the conveyor channel ladder, roller chain conveyor roadway lighting is sufficient.
2. The driver before driving; want to check on the conveyor belt and near the nose and tail, no one really observed only after the issue driving signal. Starts, the first jog

test, indeed no problem to have a formal driving.
3. Driver's clothing should be agile, cuffs, Kujiao, skirts to truss, long hair must be inside the helmet plate. Operation, the roller oiling or be particularly careful when

handling failure, non-direct hand to fiddle with rollers.
4. Conveyor running them, Gravity roller conveyor is strictly prohibited shovels or other tools scrape sticky slime on the drum, or reversal of positive deviation tool belt, otherwise, the most prone

to injury accident.
5. Conveyor ride strictly prohibited. Conveyor stops running, if not cut off the power and put up "Someone working to prohibit driving," the warning signs, prohibition overhaul,

nor stay in the conveyor belt.
6. Roadway conveyor mounted on both sides must be of sufficient width, the conveyor from the stanchions or arch wall distance not less than 0.5 meters, pedestrian side not less

than 0.8 m.
7. To prevent fires, you must use fire-retardant conveyor belt, hydraulic coupling medium must use non-flammable media and require the installation of smoke, temperature

protection device and automatic sprinklers.
8. To ensure the quality of the conveyor installation, the driver should strengthen the maintenance and inspection conveyor, abide by the rules.
