How do l choose a good concrete pump?

In construction projects, concrete pump is an indispensable equipment, which can efficiently deliver concrete to the designated location, greatly improving the construction efficiency. However, there are many types of concrete pumps on the market, how to choose the right concrete pump has become an important issue for engineers.

According to the scale of the project

Before choosing a concrete pump machine, a comprehensive and detailed understanding of the needs of the project is the first task. The size of the project is a key factor. Small residential construction projects have very different needs for concrete pumps than large commercial complexes or infrastructure projects such as bridges and tunnels.

A small project may require only a small trailer-mounted concrete pump to meet the construction needs, while a large-scale project will often require a large truck-mounted pump or pumper to ensure efficient and continuous construction due to the huge demand for concrete.

According to the construction cycle

The construction cycle should not be ignored. If the project is a tight schedule, you need to pump high efficiency, good stability of the concrete trailer pump to ensure that the project is completed on time; for the construction cycle of the project, in addition to consider the pumping efficiency, but also need to pay attention to the durability of the equipment as well as the cost of maintenance, choose the quality of those reliable, easy to maintain the equipment, can effectively reduce the long-term operating costs.

According to the concrete demand

Accurate calculation of concrete demand is crucial. According to the engineering design drawings, accurately calculate the overall demand for concrete, and combined with the construction progress plan to determine the daily and hourly concrete demand. So that in the selection of concrete pumps, you can ensure that the pumping displacement of the selected equipment can meet the construction intensity requirements.

For example, if a project needs to pour 50 cubic meters of concrete per hour, then the theoretical pumping displacement of the selected concrete pump should be taken into account in the actual pumping efficiency (generally 70% -85% of the theoretical displacement), but still be able to meet or exceed this demand.

According to the pumping distance and height

Pumping distance and height are the key parameters that determine the performance of the concrete pump. Pumping distance includes horizontal distance and vertical distance, and the pumping distance and height capacity of different types of concrete pumps are different. For short distance, low height pumping needs, small concrete pumps can be competent; but if the construction of high-rise buildings, the pumping height may reach dozens of meters or even hundreds of meters, or long-distance horizontal pumping, such as bridge construction needs to be transported to the concrete to the farther position, which requires a high pumping pressure and a large conveying diameter of the concrete pump, in order to overcome the resistance in the process of pumping, to ensure that the concrete can be be delivered to the specified location smoothly.

How to increase the efficiency of a pump?

Reasonable choice of pump model: according to the actual demand of the project, choose the concrete pump with suitable pumping height, delivery capacity and outlet pressure to avoid affecting the efficiency due to insufficient or excessive performance of the pump.

Optimize the pumping pipeline arrangement: try to reduce the bending and length of the pipeline to reduce the pumping resistance. At the same time, make sure that the pipes are firmly connected to prevent slurry leakage.

Ensure the quality of concrete: the properties of concrete such as ease and fluidity have a great influence on the pumping efficiency. The mixing ratio of concrete should be strictly controlled to ensure that the quality of concrete meets the pumping requirements.

Regular maintenance and upkeep of the equipment: check the various parts of the pump regularly and replace the worn parts in time to ensure the normal operation of the equipment. At the same time, maintain the equipment, such as lubrication, cleaning, etc., to extend the service life of the equipment.

Training of operators: the skill level of operators directly affects the efficiency of the pump. Operators should be trained professionally, so that they are familiar with the performance and operation of the equipment, and can skillfully operate and troubleshoot.
