Why did the construction site choose to use a mobile hydraulic concrete placing boom?

As the terminal equipment for pumping concrete, the mobile hydraulic concrete placing boom is used to send the pumped concrete through the pipeline to the formwork of the component to be poured. The hydraulic concrete placing boom does not need to be fixed when used, and the position and conveying direction can be flexibly changed according to the needs of the construction site. The mobile hydraulic concrete placing boom has reasonable design, stable and reliable structure, light weight and can be hoisted and transported as a whole. Adopting 360° full-rotation boom-type fabric structure, the whole machine is easy to operate and flexible to rotate, and has the characteristics of high efficiency, energy saving, economy and practicality. It has played an important role in improving construction efficiency and reducing labor intensity. Working principle of mobile hydraulic concrete placing boomFeeding systemThe concrete is transported by the mixer truck to the unloading platform outside the opening line of the excavated side slope at the upper part of the pipe body, and then unloaded into the hopper at the end of the concrete placing boom distributor, and then the concrete is transported to the upper part of the pouring warehouse through the belt conveyor system, which is controlled manually The distributor uses the control baffle on the belt conveyor to transport the concrete to the required parts through the troughs and chute.Other usesIn addition to conveying concrete into the warehouse, the placing boom can also use the electric system installed on the placing boom frame to install and dismantle large formwork, hoist and transfer materials such as steel bars and steel pipes, etc. 1flexible useIt does not need to be fixed when in use, and it can be placed flexibly. It can be placed on the floor, shelf, etc.; the structure is simple and compact, and the weight is light. It is away from the construction area and can be quickly transferred to other construction sites.2a lot of usesIt can meet the pouring requirements of some special construction work surfaces, and there is no blind area of cloth; the operation range is large, the operation is flexible and convenient, safe, reliable, and cost-effective; it is widely used in architectural and engineering construction, such as industrial and civil buildings, bridges, roads, infrastructure and other concrete structures.

The attention matters of fitting the new axial plunger pump to concrete pumps

Regarding the mixing pump part (The new piston pump), there are some thing very important when you receive it and equip the new one on to the machine, I have to make you clear about this earlier to prevent it wouldn't be broken again.1. After the new pump fit on to the machine, you have to fill full hydraulic oil into the oil return hole (or say return opening/ oil return port), must full it and bleed off the air in it, it is very important and necessary. This is to prevent the pump lacking oil transiently, dry grinding and then cause slipping shoe wearing heavily and exceedingly, and even cause broken directly, so, you have to pay attention to this step.2. Please keep the cleanness of the hydraulic oil, the filter in the oil tank you have to alternation regularly, do not wash it, as you can't wash it clean at all, please use the new to take place the dirty one.The above 2 suggestions is very important to the pump, and please feel free to ask if you have any questions about it.

Causes and treatment methods of mortar spraying machine blockage

In the mortar transportation and spraying process, the mortar will block the pipe due to various reasons. The mortar spraying machine is a special coating equipment using spraying technology. The principle is to control the air flow to instantly push the air reversing device to change direction, so that the piston of the air motor can make stable and continuous reciprocating motion. Generally caused by the following reasons, the pipe blockage generally occurs in the early stage of use. For the first use of each day, the pipe must be lubricated with water, and a bucket of cement (material: powdered hydraulic inorganic cemented material) slurry is used to bring the material to life before starting. Spray normally. The mortar stays in the pipeline for too long and causes pipe blockage. The main reason is that the long-term pause causes the mortar to set up, resulting in reduced flow and pipe blockage. Generally, the machine is shut down for about 30 minutes to start the machine for 5 to 10 seconds to let the mortar flow Just fine. The pipe blocking phenomenon caused by too high pressure during spraying, the conveying distance is too far during spraying, the height is too high, the pressure is too high, and the other is the blocking of the foreign body in the spray gun mouth, which causes the pressure in the mortar tube to rise, causing water bleeding at the interface Phenomenon, leading to the phenomenon of pipe plugging, which is generally a precursor to the phenomenon. During the spraying process, the flow rate (unit: cubic meters per second) is significantly minimized, and the working pressure gradually increases. Timely shutdown, the early stage of pipe blocking is generally cleaned at the discharge port and the takeover. If the pipeline is seriously blocked due to timely shutdown, it can only be eliminated by cleaning the pipe with water. Select the appropriate hose to flush from the bottom right.
