Because of its large displacement and high pressure, Fine aggregate concrete delivery pump It is widely used for pouring construction. After the use of fine stone pump, it should be cleaned as soon as possible to prevent mortar solidification, and no longer use after construction. Usually wash with water. Judging from the design structure of the fine stone pump, the gearbox can rely on its own design to achieve reasonable heat dissipation. During the working process, the transmission will generate steam. The accumulation of a large amount of gas causes the internal pressure of the system to rise. The top of the gearbox is designed with ventilation holes. The ventilation hole is actually a check valve, similar to the pressure reducing valve of the pressure cooker. Function, under normal circumstances, the valve is closed, when the system pressure rises, the check valve will be discharged by steam.
The application of fine aggregate concrete delivery pump has laid the foundation for the development of the industry for many years. In the future development, we will not forget the original heart and provide good performance products for everyone. I hope that everyone can advance and retreat with us and move towards a better future. Attention should be paid to the quality problems of fine aggregate concrete pumps.
(1) ground grinding: Cement labels are not enough or use overdue cement, or the water cement ratio is too large, the pressure is not enough, the maintenance is not good or not timely, the standard should be strictly implemented, and should be carefully operated and strengthened.
(2) hollow drum rupture: the sand is too thin, the base of the contact surface is not clean, the surface is not smooth, the edges and corners and the door are broken, the brick layer is too high, the brick layer is not wet enough, the local dehydration or the ground does not divide. These defects should be taken ahead of schedule.
(3) the ground is uneven or leaking: it is easy to leak or uneven around the corners of the ground and the pipes.
(4) pour water: when washing cars, you should drown rooms with floor drain, such as toilets, kitchens and so on, so as not to reverse water or water.
When we control the fine concrete pump, there are still many things to pay attention to, and the most important thing is safety. During operation, attention should be paid to wearing safety helmets and protection of all safety at construction site. Regularity, followed by parking. The ground required to park on the ground is horizontal. If so, it will produce a smooth effect. However, horizontal support for appearance is also a necessary condition. It can't stay in the hole. This is risky.
When it comes to the maintenance of fine concrete pump, I believe many people know that when they use it, they need to maintain their body. If they are found to have dirt and obstructions, they need to be cleaned in time. Secondly, after the application is finished, add water to the mixing cylinder for 1 to 2 minutes, and check the reliability of the clutch and brake equipment. Every time you leave work, you should clean the stain carefully and wash it carefully.
