Concrete mixing transport vehicle repair and maintenance

Repair, maintenance and a concrete stirring transport vehicle

The car used as transportation of concrete stirring transport vehicle, in terms of maintenance and repair must comply with the provisions of the Ministry of communications in 1990 13 orders, the implementation of the "regular testing, forced maintenance, timely repair" maintenance and repair system. In this context, combined with the actual situation of concrete stirring transport vehicle, good maintenance and repair. In the daily maintenance, concrete mixer truck except as routine maintenance of automobile engine, chassis and other parts, also must do the following maintenance work.

1, cleaning concrete tank (mixer truck drum roller) and inlet and outlet

Because of the concrete in a short time will solidify into lumps, and paint on steel and have a certain corrosive, so every time the use of concrete tank, cleaning adhesion is daily maintenance must seriously work carried out in the concrete tank and the inlet and outlet of the concrete. Including:

A. every time charging before flushing with water inlet, the inlet when in charging moist;

B. filled with water to clean water tank with the car comes in charge at the same time;

C. loading washing after feeding mouth wash, feed near the mouth of the residual concrete;

D. to the site after unloading, flushing out feed channel, and then to the concrete tank and cleaning water 30 - 40 L; keep the concrete tank forward slowly rotate in the vehicle when you return;

Next time before you go E. filling concrete tank sewage;

F. the end of each day when thoroughly clean the concrete tank and inlet and outlet around, guarantee not to stick with cement and concrete caking. The above work as long as one does not

Seriously, has caused great trouble will give the future work.

2, the maintenance of the driving device

The action of the drive device is driven to rotate it by concrete tank, hydraulic oil tank and a cooling device of power takeoff, Wan Xiangzhou, hydraulic pump, hydraulic motor, the control valve, consisting of. If this part due to failure to stop work, concrete tank will not rotate, this will lead to concrete scrap car, even the whole pot of concrete setting in the tank, causing scrap concrete mixer truck. Therefore, the driving device is reliable or not is must attach great importance to the problems in use. In order to ensure the driving device is intact and reliable, should do the following maintenance work:

A. universal rotating part is the fault of multiple parts, should be timely grease, and regularly check the wear, timely repair replacement. The team should have spare cardan shaft assembly, to ensure that the event of failure to return to work in a few minutes.

Ensure the cleanliness of the hydraulic oil b.. Concrete mixing truck working environment is bad, we must prevent the pollution of cement sand into the hydraulic system. Hydraulic oil according to the manual requires regular replacement. Once the inspection found that hydraulic oil mixed with water or sediment, must immediately stop cleaning and replacement of hydraulic oil, hydraulic system.

C. ensure that the hydraulic oil cooling device effectively. To regularly clean hydraulic oil radiator, the radiator is avoid cement plug, check the radiator electric fan is functioning properly, to prevent the hydraulic oil temperature exceed the standard. The hydraulic part as long as the guarantee of clean hydraulic oil, the general failure not much; but to different manufacturers, the service life is not the same.

3, pay attention to the tire repair

 

                     

 

The maximum of the thermos bottle

At this point, a frequently asked question is: "if the thermos flask is so good insulation, so how to cool the spacecraft?" Spaceship accumulation of heat from its electronic equipment, fuel cell, the rocket engine and the received solar radiation, etc.. All of these heat must have a place to go, otherwise the spacecraft will overheat. However, the spacecraft is a hot water bottle floating in the world's largest (in the vacuum of outer space). Then the space ship how to deal with it extra calories?

The original heat dissipation is a very important part of the space ship design process. For example, if you look at this page, you will see Skylab (Space Experiment Station) with a gold plated coating, used to reflect the infrared radiation from the sun, there is also a large radiator to dissipate the heat. Space radiator can only use infrared radiation to dissipate heat, so it must be a radiator on earth than similar large many. In the face of the earth, convection plays a main role in the cooling process, so almost all radiator use a fan to enhance convection effect. Similarly, the medial space ship cargo port door is also provided with a radiator. Once the spacecraft into orbit, one of the things the staff the first thing to do is to open the door of the radiation.

Some research institutions for the chemical analysis of Sheng 98 days five pounds in boiling water hot water flask wall furring, heavy metals contained amount of cadmium were 0.034 mg, Pb 0.12 mg, iron 24 mg, 0.21 mg and 0.44 micrograms arsenic, mercury. The scales have the possibility to increase the concentration of heavy metals in drinking water. When using a thermos flask scale change containing other liquid, especially plum juice, beer and other acidic liquid, some heavy metal elements in the scale of the precipitates due to chemical reaction, dissolved in water or other liquid to. When people long-term small put these heavy metals intake, it may cause the human digestive, respiratory and nervous system, hematopoietic lesion and dysfunction. So, on this scale must not look down upon! Therefore suggested that people should regularly to eliminate this kind of scale.

The Advantages For Choosing LED desk lamps

Many people have been hearing a lot about LEDs lately, like how they are used in TVs and light fixtures. Today, you can even purchase LED desk lamps. However, very few people actually know why LEDs are so important or what they really are. Fortunately, this article can provide you with all the information you need on LEDs and the desk lamps that use them.
LED lamps are also more energy efficient than traditional lamps that use bulbs. This means that they require less electricity to operate, so it is possible to save money on your electric bills by using them.
LED desk lamps are now available in a wide range of styles and colors. There are many highly compact and contemporary styles that will fit nearly anywhere, while still producing a very bright light. You can also get lamps which swivel and bend.
For task lighting in a home office space, an LED desk lamp does the job efficiently. This type of bulb is much more energy efficient than typical bulbs, so you can reduce your expenses of doing business, particularly if you work at home.

Aluminum Coil: An Earth-Friendly Industrial Material

Whether a project calls for aluminum foil (thinner than 0.006 inches in thickness) or aluminum sheet (0.006 inches to 0.070 inches in thickness), aluminum coil is behind the manufacturing process. Aluminum coil is formed by taking one continuous strip of aluminum and coiling it into a roll.
Some of the advantages of pre coated aluminum coil is that it is lightweight, heavy duty and able to resist corrosion. By a process called anodizing, whereby the aluminum surface is coated with a protective oxide, that corrosion resistance can be improved even further. As a result, manufacturers who need to increase their productivity and require parts that can withstand the elements rely on aluminum coil to get the job done.
Why might they opt for aluminum coiling over another durable material like steel or copper? At about 33% the density and weight of steel, aluminum renders parts that are much lighter, thereby reducing handling costs and shipping fees. What’s more, is the cost is about 50% that of copper.
In fact, according to the Air Conditioning, Heating, Refrigeration News, aluminum versus copper has become “The Great Condensing Coil Debate.” In that article published by the industrial news source, while controversy stirs about one versus the other, one thing is clear. Condensing coils made from aluminum have made air conditioning more affordable. “That (aluminum coil) brought the cost of an a/c system down, making it more palatable to consumers and builders.”
But the heating, ventilation and air conditioning sector isn’t the only industry in which aluminum coil is used. The transportation industry, in fact, is the largest user of the product in the United States, accounting for close to 30% of all that is produced in the nation. Indeed, the average car driven in this country contains over 275 pounds of aluminum, and some luxury car makers use aluminum sheeting to make the entire bodies of their vehicles. Perhaps that’s why aluminum has become the most abundantly produced non-iron metal.
In the construction industry, aluminum coil is also being used more and more frequently as trim to cover base materials on homes. Because the aluminum can be anodized with a decorative oxide and comes in a wide variety of colors, it provides a pleasing finishing feature. Best of all, it is easy to install, making it a nice home project for the do it yourselfer. The most typical way in which aluminum coil is put to use in homes is as a trim finish for windows, soffit boarding, siding and roof edging.
Beyond these industrial advantages, aluminum is extremely kind to the environment thanks to its ability to be recycled. That ecological friendliness is further enhanced by aluminum’s ability to be recycled an infinite number of times. In the transportation industry alone, that adds up to substantial benefits to the earth. In concrete terms, the average car is made up for about 7% aluminum, yet aluminum
