Mixing pumps are often used in the current construction of new rural areas. They can not only perform on-site mixing, but also transport concrete. It is suitable for reservoir construction, residential building construction, tunnel engineering, and water conservancy engineering construction projects. Many people are very concerned about the operating conditions of concrete pumps when they are in use, but few people pay attention to the correct way

QZHP-3016E concrete wet spraying trolley is suitable for large-scale highway, railway tunnel construction, slope support construction, large-scale water conservancy and hydropower project tunnel, culvert construction, and subway, various civil and military construction projects, etc., to meet the construction requirements of shotcrete .

Concrete delivery pump, also known as concrete pump, consists of pump body and delivery pipe. It is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly used in house construction, bridge and road construction. Concrete pump is a construction equipment that relies on pressure to transport concrete through pipelines. It is equipped with special pipelines,

Advantages of installing an air compressor: Saintyol DAWIN 3016B concrete wet spray trolley is equipped with a 75kw air compressor. There is no need to connect additional air sources on the construction site. It is fast and convenient to transfer and move vehicles. Greening, slope protection and other projects provide a strong guarantee, high efficiency, good stability, fast movement and other advantages, is a good helper for tunnel construction.

Saintyol DAWIN small wet spraying machine has high construction efficiency, low dust concentration in shotcrete operation, low rebound rate, accurate water-cement ratio control, fully hydrated cement, high strength of shotcrete, great cost savings, no dust generation, In turn, the impact on workers and the environment is not large, and it is suitable for various working environments.

Most of the fine stone concrete pumps use a hydraulic system. The piston rod in the main oil cylinder generates mechanical pressure under the power. When the piston retracts, it generates self-priming in the conveying cylinder. The concrete in the hopper is under the action of atmospheric pressure and the boost of the stirring blade. Under the action, it is sucked into the conveying cylinder through the suction port of the slide valve.

The operator of the concrete mixing pump should check whether the thickness of the brake pads of the braking system is too thin. If they are worn to a certain extent, they must be replaced. It should be noted that if the brake drum wears too much, even if the thickness of the brake pads is full, it may cause The brake camshaft travel is too long, causing the brake shoes to die. Also check to see if the brake camshaft grease passages are not blocked.

The general concrete spraying process is divided into dry spraying and wet spraying. For dry sprayers and small wet sprayers used for manual manual operation, the amount of rebound and drop of the spray is still very easy to control. If there is a large amount of falling, it is the problem of the ratio of sprayed concrete and the accelerator. For large wet spraying machines (manipulators), there are many reasons for falling sprayed concrete.

With the construction of various mine roadways, railway and highway tunnels, water conservancy culverts, and various underground projects in the country, the internationally advanced support method of shotcrete support is widely used. Concrete sprayer is the main equipment for this operation. There are three major problems with dry sprayers: ① large dust, ② more rebound, and ③ poor quality. The country is now vigorously promoting wet wet spraying, which has the advantages of low dust,

Precautions for pump operation:
1. The place where the pump truck is in place is flat and solid, and there are no obstacles around. Pump trucks must not be parked on slopes. The parking position meets the needs of pouring, and does not obstruct each other with other on-site machinery, which affects the construction progress and the safety of construction workers.
