Introduction to inclined secondary structure column pump

In order to ensure that the concrete conveying pump has a large conveying capacity, a certain outlet pressure, and matching economic power, constant power plunger pumps are mostly used in the design of inclined secondary structure pumps; After the constant power value is selected, when the outlet pressure increases, the output displacement of the oil pump will automatically decrease to reach the value corresponding to the power design; If we want to achieve both high outlet pressure and large conveying capacity. The inclined secondary structural column grouting pump adopts an automatic refueling and bypass self circulation system, which not only facilitates refueling, but also finely filters the new oil to prevent human pollution. This ensures low failure and high reliability of the oil pump, valve group, motor, and oil cylinder. The unique fuel tank design and air/water cooling system ensure continuous operation in high temperature environments, with oil temperatures not exceeding 75 degrees Celsius. The adoption of large capacity high-pressure imported energy storage devices and their excellent buffering performance design make the swing system strong and powerful. The swinging torque is more than twice that of similar models. Greatly reduces the requirements of S-pipe valve for concrete medium, and allows for easy pumping of cushion concrete during construction. The whole machine lubrication system adopts automatic lubrication, which runs reliably. The unique self-lubricating design of the concrete cylinder ensures low wear and long service life of the concrete cylinder and piston.

Cleaning of inclined secondary structural column pump

1. Prepare cleaning tubes, cleaning supplies, and other related equipment. Before starting the homework, the pipeline must be lubricated with cement mortar prepared according to regulations. Unrelated personnel must leave the pipeline.
2. The legs should be fully extended and firmly supported, and the fabric rod should not be started until it is fixed. The fabric rod can only rotate after raising the bracket. When extending the fabric rod, it should be done in sequence. It is strictly prohibited to use fabric poles to lift or drag objects.
3. All parts of the control switch, adjustment handle, handwheel, control sweat, plug, etc. should be reset. Unloading of hydraulic system.
4. Various instruments and indicator lights should be monitored at all times, and any abnormalities should be promptly adjusted or dealt with. If there is a blockage in the conveying pipe, reverse operation should be carried out to return the concrete conveying pump to the hopper, and if necessary, the pipe should be removed to eliminate the blockage.
5. The parking brake and locking brake of the pumping equipment should be used simultaneously, the tires should be wedged tightly, the water supply should be normal, and the water tank should be filled with clean water. There should be no debris in the hopper, and all lubrication points should be lubricated normally.
6. When the concrete conveying pumping system is under pressure, no conveying pipelines or hydraulic pipelines shall be opened. The safety valve of the hydraulic system must not be adjusted arbitrarily. The accumulator can only be filled with ammonia gas.
7. After the homework, all the concrete in the hopper and pipeline must be discharged, and then the pump, hopper, and pipeline must be cleaned. When washing the pipeline with compressed air, no one shall stand within 10 m in front of the outlet end of the pipeline, and a metal basket shall be used to collect the washed foam rubber and gravel particles.

Introduction to the construction of inclined secondary structure column pump

During concrete construction, the inclined secondary structural column pump is normally equipped with two fixed concrete delivery pumps on site. During foundation construction, due to the large amount of concrete poured at once, four concrete delivery pumps are used simultaneously. In addition, the pump model should be selected reasonably to fully utilize the equipment performance. Due to the high pumping height, the pumping pressure increases, and the lateral pressure borne by the concrete pump pipe also increases. Therefore, high-pressure pump pipes need to be used. When multiple fine stone conveying pumps are simultaneously pumping or combined with other conveying methods to transport fine stones, their respective conveying capacities, pouring areas, and pouring sequences should be predetermined. And clear division of labor, mutual cooperation, and unified command should be established.

Characteristics of inclined secondary structure column pump

1. Compact and simple structure, reliable performance, and economical price

2. Easy to operate and maintain

3. Lightweight, wheeled design, easy to move

4. Inject thick slurry with high ash to sand ratio and special requirements for high concentration design.

5. It can be filled with slurry with a high ash to sand ratio and a wide range of sand particle sizes.

6. Sustainable grouting to avoid the instantaneous pulsating pressure of piston type national universities.
