Essential knowledge of concrete pumps before purchase

图片
Concrete pump  is a kind of cement concrete machinery, and it is the main machine equipment in engineering machinery construction. Its structure is adapted to its function. Trailer concrete pump continuously transports concrete to the casting site along the special pipe, and at the same time completes the transportation of concrete in the vertical and horizontal direction. Such working procedures are efficient, of good quality, highly mechanized and free from field conditions, and reduce pollution. Haomei trailer-mounted concrete pump are widely used in many large-scale concrete construction projects. It is an efficient and economical conveyance machine if the site is narrow, the pouring face is small or the building with dense reinforcement is cast. Of course, there are two sides to everything, and the concrete pump is no exception. It has the limitation of lifting distance and casting area, which have influence on its use range. The concrete p...

Daily maintenance operation of concrete pump

图片
Many construction sites use  concrete pump  to improve the efficiency of the construction quality, but the working efficiency of the concrete pump is not only related to its  quality, also has a lot to do with the daily maintenance work. So how can we maintain the  trailer concrete pump  on earth? In general, the daily maintenance of small concrete conveying pumps includes inspection, cleaning, lubrication, fastening, adjustment, leak detection, and hydraulic oil replenishment. Specifically, the maintenance of the concrete conveying pump mainly includes the following aspects: 1. Generally, after each mechanical operation, cleaning is an indispensable process for the whole concrete pump. In general, to ensure that the concrete pump clean, concrete pump can be protected from the outside natural environment. 2. Good lubrication can effectively reduce mechanical wear and tear, so it is important to pay full attention to lubrication in maintenance. ...

LB2000 asphalt mixing plant  is a kind of road top use device, and for this kind of equipment, what kind of requirements should be met when using it? First, is it to achieve a good quality of finished product, for this is one of its work purposes.  Another is that it is to achieve a good stability. When using  asphalt concrete plant , the user must first pay attention to its performance, if a device can achieve very good effect, but it doesn’t meet the requirements in this respect, in the end it on its own production, also cannot achieve satisfactory. And on its own structure, asphalt mixing plant also needs to achieve simplicity. As we all know, for this kind of equipment, it is a kind of large equipment, but under this condition, to achieve good simplistic, the operation of the whole above will have certain reduction, and when we buying it, we can reduce the cost on some certain. 

Notes for concrete boom pump truck

图片
1. After  concrete placing boom  runs into the construction site, the operator immediately gets off, commands vehicle safety into the construction site, pays attention to the sub-grade. 2. Open the boom frame and lower the hose test arm frame to see if there is any obstruction. Empty the  placing boom  for a few minutes and manually lubricate it until the oil comes out of the large and small bearing pedestal. 3. When pumping, first hit the mortar and then hit the concrete. For example, after mixing the mortar at the site into the hopper, add water and reverse pump more than ten times, so that the mortar can be fully and even before the positive pump. At this point, the boom hose is placed in no man’s place, and the concrete material is moved to the designated position for pumping. It’s important to remember! 4. At the beginning of pumping, check whether the supporting leg is firm and reliable. If not, fasten it again. 5. ...
