Introduction and parameters

Introduction of fine aggregate concrete pump products:

    Fine aggregate concrete pump It is a mortar conveying equipment specially developed for the characteristics of floor heating. It is suitable for large area and high efficiency construction of fine stone concrete filling layer or mortar filling layer in floor heating engineering.

Matters needing attention in operation of fine aggregate concrete pump:
 
The fine concrete pump should be pumped first before pumping. At the same time, check whether the seal of each pipe is in good condition, ensure that there is no water seepage phenomenon, and then pump the pipeline lubricant. After the pipeline is lubricated, concrete pumping can be carried out. If there is a blockage, it is recommended to remove a pipe in front of the blockage, remove the dehydrated block inside the pipe, and then connect the conveying pipe to start pumping again.
When starting or stopping pumping, contact the operator at the front hose of the fine stone pump. The construction personnel shall not stand at the outlet of the pipe to prevent accidental injuries caused by concrete ejection. When the fine stone pump is running, it is not allowed to reach into the hopper and washing room. It is necessary to fix the conveying pipeline of the fine stone pump and not to bend the conveying hose to avoid explosion. The end of the conveying hose must be held at the corner of the building, so as to prevent the hose from shaking or the concrete ejecting, causing the operator to fall and get hurt.
Slump fluctuation should not be too large, and the variation range should be within 80 to 230mm. When slump is too low, it is not allowed to mix water in the hopper, but add cement mortar.
When the blockage pipeline is again pumped, the construction personnel shall not approach the hose to prevent the hose from swaying rapidly and injecting concrete.
During the pumping process, the concrete position in the hopper should always be above the stirring axis, and the pump operation is not allowed when suction or no material is available. If the two pumping interval is longer and the pump is suspended, it is recommended to pump once every 15 to 30 minutes, 1 to 2 strokes of the positive and reverse pumps, so as to prevent the concrete from condensing in the conveying pipe.
Safe operation of fine concrete pump:

1, fine stone concrete pump should be placed on a solid and smooth floor. There should be no obstacles around. After setting down the outrigger, the fuselage should be kept stable.
2, check before operation, confirm that electrical equipment and instruments are normal, each switch button and handle are in the correct position, the fastening points of the mechanical parts are firm and reliable, the chain and belt tightness meet the requirements, and the transmission parts need to operate normally.
3, turn on the power supply, the equipment shell need to do earthing protection. Start the motor to see if it works properly.
4, the laying of the pump pipe should meet the following requirements: the horizontal pumping pipeline should be laid in a straight line; the pipeline should be supported and fixed, and the wooden cushion should be cushioned between pipes and fixtures, so that it should not be directly connected with steel bars or formwork.
5, the hopper grille net and other safety devices can not be removed during operation. Do not climb or ride the pipeline, do not put your hands into the valve body, and do not remove pipes when pumping.
6, when cleaning the pipeline, the operator should leave the outlet and elbow joints. If compressed air is used to clean the pipeline, there should be no 10m and equipment in the outlet of the pipeline.
7. After the operation, the hydraulic system will be unloaded and the control switch will return to its original position.
Some points for attention in the construction of fine aggregate concrete pump:

1, component inspection: when the fine concrete pump is being built, check the hydraulic components. If there are any problems found, we should first find out the causes of the failures and repair them. Then check whether the hydraulic system is running normally, whether there are any wear and cracks on the hoses, connectors and cylinders, so as to ensure that the connectors are complete and fastened. If the pipeline is damaged, it is necessary to replace the damaged pipe.
      2, fastening: fastener is also often needed for the construction of fine aggregate concrete pump. It is necessary to check whether there is loose connection between the fastening bolts, the bolts of the concrete cylinder, the bolts and nuts of the tie rod, the connection bolts of the cylinder joint and the frame, whether the S valve discharge port connection bolts are fastened properly, and there are places prone to leaking, liquid level gauge, oil drain plug, oil pump, oil pipe joint, oil cylinder, etc. These parts also need to do well in preventing oil leakage. Otherwise, they will not be able to ensure the smooth operation of the fine concrete pump and cause more troubles.
