With the rapid development of highway and super highway in our country, the volume of passengers transport and of freight highway is rising incessantly. The rapid development of highway forwarding agent prompts the development of car manufacture. How to make the moving car unblocked and do its best safely and normally, it is very important to maintain the vehicle during its normal moving, besides its designed function and quality. The vehicle concentrated lubrication system is a technology which is designed to satisfy and maintain the vehicle. It can be applied to all kinds of coaches and trucks. It is automatic (at regular time and quantity) and generally it can be used for 15 years.
Since 1980' , this system has been widely applied abroad. Fox example, Mercedes Benz and Volvo have treated it as necessary equipment. While because of its technology and high price, it is not widely applied in our country. Some luxious coaches were installed with this kind of system made abroad but they cost high. If it was installed in normal couch, trucks and engine it would be too expensive to accept by our customers owning to these points, our corporation produced this system which is more reasonable in price and more suitable for china. With the help of Germany technology. It has been widely applied in our vehicle manufacture recently.
● What is the vehicle concentrated lubrication system.
There are 20-40 numbers of friction pairs in different parts of the chassis in the coaches and trucks. It is a completely close system. Which connects the dispersed points by oil pump. Pipeline and divider. When the vehicles moves. It can automatically supply the lubricate grease to these points at regular time and quantity. By this way. These numbers of friction pairs can be kept in good condition, prolong the working life and prompt the vehicle to the hest advantage.
●
Why do we use the chassis concentrated lubrication system.
By this system, the life of the vehicle life can be 4 or 5 times the inpouring oil by hand. The maintenance cycle will be prolonged to 40000 -50000km . And we can dispel the troubles caused by inpouring oil by hands. Furtherinove. We can reclaim the invest which is used to buy it in two years.
●
The basic components of this system
It consists of pump unit, divider, control unit, detecting element and some other accessories.
*Pump unit: the heart of this system, by which the lubricate geese can be exported through the oil storage tank under the pressure or the pump.
*Divider. By which the grease can be at regular quantity and then flow to each points. Then each point can be lubricated properly, incaplible of the phenomenal of less oil or more.
*control unit: the micro. Computer control device, it is the median of the whole system. It determines the interval and running time and receives the signals from the detecting unit.
*detecting unit: the press sensor, it detects the pressure and then transmit the information to the control unit.
*other accessories: mainly including pipe. Secondary pipe, cable, and all kind of connections, which connect every part into a closed system.
The regular quantity of the divider and the regular time of the detecting unit make up of the automatic concentrated lubrication system at regular time and quantity.

lubricative medium
In north and the places where the temperature below 0 ℃ for more than 15 days, the vehicles should use the lubricative medium “ 000” or “ 00” inorganic gelled extreme pressure grease. Stated by our corporation. In the place where the temperature bellows 0 ℃ less than 15 days, the vehicles should use the normal. NLG1-000 or 00 lithium extreme pressure grease. While the place where the temperature doesn't below 0 ℃ , the vehicles can also use NLGI-O lithium extreme pressure grease. The polluted or secondary grease can't be injected. it the oil-box. Or it may damage the system and the number of friction pares.
Design and Installation.
1、 determination of the lubricatire points.
Lubricatire points are all the moving number of friction pares except the unival joint of the propeller shaft. That is the friction points which doesn't rotate 360 ° 2、Determination of the quantity of oil in each point once. (generally the interval between supplying oil time is about 10 or 20 hours; the total quantity in a year must be more than the capacity of the oil-box .)
3、 Determination of supplying quantity of the lubrication system
Q=q1+q2+q3=(1+20%)q1(m1)+1(m1/m ) × L(m)
Q---fuel delivery of the system.
q1---the total of each lubricative point
q2---safely high added value.
q3---the depletion of the main pipe.
L---the length of the main pipe.
When the maxiuin inpouring quantity can't satisfy the system, you should install a second pump. When the KR pump connects the vehicle. The length of the main pipe is more than 17m and the temperature belows -20 ℃ , you also need install a second pump.
4、 Installation
4.1、Instructions for the pump installment
The pump should be installed vertically, in less polluted area. It should be convenient to maintain and easy to observe and manipulate. If conditions permit, there should be a single door besides the pump.
4.2、Instrllctions for the divider installment.
The divider should be installed in less polluted area, and it should be easy to easy to install pipes and observe. The dividers can be connected as one group. By red copper. And then connect with the main pipeline. The flowing quantity is 0.1m , 0.2m , 0.4m once. Corresponding to white. Yellow. Red. The end of the secondary pipeline should be connected with the lubricative adaptor.
4.3、instructions for the pipe of the lubrication system.
4.3.1 the main pipeline should use the Ф 10 Х 1 dan(or red copper pipe.)
4.3.2 the maxium length of the of the pipe between the divider and the affiliated pipeline should be less than 3m . and it should be as short as possible when designed. The affiliated pipeline should be nylon pipe and install k04 nylon sleeves.
4.3.3 The pipeline should be cut vertically. Neither damage and scribe the pipe nor crush it flat.
4.3.4 The distance between the main pipe and the affiliated pipe should be short and avoid too many elbows. (when bended, the minimum radius of the Ф 10 Х 1.5 and the 4 Х 0.75 nylon pipe. Are.R89 and R38). By doing this, the system will have less pressure and make the pipe fair ness.
4.3.5When you install the pipe, you should remove the chips and rubbish and keep it clean.
4.3.6 When you install the pipe you should make the pipe 1% longer than the line. If you need bend, don't twist the pipe.
4.3.7The main pipeline and the affiliated pipeline should avoid the power source such as the engine and the air-conditioner and the spring slab bending slot.
4.3.8The main pipeline and the affiliated pipeline should be covered by waving pipe.
4.3.9 The pipeline which goes through the beam and moves should use the steel wire sleeves.
4.3.10 All the pipes should be bundled. Wedged or hopped in the chassis.
4.3.11 The connection should be installed steadily and shouldn't leak oil.
4.4 instructions for system debugging
4.3.1 when you debug the system, you should open every single ultimatum.(that is you don't close the kg16 stopper or the pressure transducer). Push the handy lubricative bottom. And make pump close the kg16 stopper or connect the pressure transducer.(expel the air).
4.3.2 The push the handy lubricative button until it reaches 60s. When it reaches 60s, push it again.
4.3.3 If you find the oil site doesn't flow the oil, you should use handy fuel truck nozzle with stated grease to make it fairness. Then see if it works well when the pump operates.
4.3.4 After the debugging, inject 80%-90% of the oil-box capacity.
4.5special attention: when you install cab and repair, don't make the solder spark damage the pipeline, sleeves, wire, if damaged, it must be changed.
