Concrete Mixing Pump Winter Operation Precautions

Concrete mixer pump is an important construction machinery, which is widely used in various building construction and road construction. However, in the cold winter, the operation and running of concrete mixer pump will be greatly affected, and some special safety measures need to be taken to ensure the normal operation and safety of the equipment.

When operating the concrete mixer pump in winter, the antifreeze in the water tank of the diesel engine and generator set must be replaced to prevent the water tank from freezing and cracking. In addition, the water in the concrete mixer pump tank needs to be filled before construction and drained in time after construction to prevent the concrete cylinder and water tank from freezing and cracking. If conditions are available, hydraulic oil can be added directly to ensure the normal operation of the hydraulic system. The water in the water cooler should also be drained in time after each construction to prevent the water cooler from freezing and cracking.

When starting the concrete mixer pump in winter, you need to pay attention to the fluctuation range of the voltmeter pointer. If the fluctuation range is lower than 340V, in principle, construction is not allowed. This is because under low temperature conditions, the viscosity of hydraulic oil will increase and the fluidity will decrease, which will lead to an increase in the flow resistance in the pipeline. When the hydraulic oil viscosity is very high, the main oil pump under load working condition will have difficulty in absorbing oil and may even appear the phenomenon of "empty suction", which leads to excessive wear of the main oil pump due to poor lubrication. Therefore, before the official pumping construction must be fully preheated.

In winter, concrete pouring should be done during the daytime as much as possible, and the pouring temperature of concrete should be increased to reduce the cooling time. The concrete portion after pouring should be insulated to prevent pre-freezing of the concrete. These measures help ensure the quality and strength of the concrete and reduce construction risks.

In addition, to better cope with the operation of concrete mixer pumps in cold weather, the following points need to be noted:

1. Pay attention to maintenance: concrete mixer pumps are prone to icing and clogging during winter use, therefore, regular maintenance and servicing of the equipment is required, including cleaning and replacing oil, cleaning and replacing filter elements, etc.

2. Choose suitable concrete ratio: The choice of concrete ratio directly affects the performance and anti-freezing performance of concrete. In cold weather, suitable concrete ratio should be selected to ensure the strength and frost resistance of concrete.

3. Choose the appropriate concrete placing time: In cold weather, the concrete placing time needs to be avoided in low temperature and high humidity as much as possible, and also needs to be avoided at night.

4. Pay attention to heat preservation: after the concrete is poured, heat preservation measures need to be carried out to ensure the initial setting and maintenance process of the concrete. At the same time, in the case of equipment shutdown for a long time, insulation measures are also needed to prevent the equipment from freezing and other conditions.

The safe operation of concrete mixing pumps in cold weather requires a series of measures to ensure the normal operation of the equipment, from replacing the antifreeze, filling the water, draining the water, preheating the start, and pouring the insulation. These measures not only help to improve the efficiency and quality of the equipment, but also help to protect the life of the equipment and extend its service life, as well as to protect the personal safety of workers. Therefore, when using concrete mixer pumps, it is important to observe the above safety operation guidelines to ensure the safe and efficient operation of the equipment.
