Summarization of hydraulic excavation system (sand slurry pump) conveying system

Hydraulic excavation equipment is to simulate the impact of water erosion in nature, using the role of hydraulic excavation, transport earth, filling construction machinery and equipment. Water through the high-pressure water pump produces pressure water, high-speed water jet through the nozzle of the gun, the mud (sand) soil cutting, crushing, humidification to form a slurry of liquid. From the PNL vertical mud pump transported through the pipeline to the soil field. Long-distance transportation by BS sand pump mud pump destination. Hydraulic excavation and filling units flushing, loading, transport, filling, ramming and other five processes, with high efficiency, low cost, good quality, the construction is not affected by climate and other advantages. Has been widely used in the excavation of the river, dredging, beach governance, farm construction and transformation, hydraulic, foundation piles, farmland, low-lying land reform, agriculture, environmental protection and other fields. The unit's popularization and application has been trusted by construction units all over the country. Unit system mainly by hydraulic soil, digging and conveying and distribution equipment and other components. Hydraulic ground equipment by the motor, high pressure water pump pipes, water guns and other components. Excavation and filling, transportation equipment by the motor, PNL vertical mud pump (BS-type sand slurry pump), pipelines, buoys, power distribution equipment from the distribution cabinets and waterproof cables and other components. BS sand slurry pump is our company in advanced, practical and economic principles, developed a new generation of highly efficient wear-resistant, centrifugal sand slurry pump, with high efficiency, reasonable structure, reliable, easy maintenance, low operating costs It is widely used in industries such as mines, farmland reconstruction, metallurgy, electric power, environmental protection projects, national defense projects, river dredging and pile recycling. It plays a key role in hydraulic excavation and dredging in particular. To achieve the long-distance transport of soil (which can be used in tandem). BS sand pump mud pump pressure seal device to solve the shaft seal leakage, short service life and other issues. (Specific technical parameters and installation methods can refer to the instructions or consulting technology development department) High-pressure water pump according to site conditions, a reasonable selection. According to the specific conditions, you can not mud pool, BS sand slurry pump can be used one or more tandem long-distance transport construction concise: a high-pressure water pump connected to two water cannons. A mud pump is working on the mud. According to the actual situation can be supplied by 4-6 sets of vertical mud pump BS sand pump mud pump work. The specific work is decided by the actual situation.

Sandwich Panel

What are the methods for judging the pros and cons of sandwich panel?
The material of the sandwich panel directly affects the later use. Sandwich panels are the main building materials for Prefabricated House and Steel Structure Warehouse. If you want to choose high-quality panels, you must have an understanding of their basic quality. There are many types of boards on the market, and their core materials, steel plates, adhesives, etc. are different, and the quality will also be affected. So how to judge its pros and cons?

check edge
Because the sandwich panel has several layers, it is difficult to judge its internal quality from the surface. Therefore, it is still necessary to observe its exposed edges first, and it is necessary to pay attention to whether its cross-section is clean and ensure that it is tight. If there are problems such as graying and impurities, then there must be problems in quality, so it is still necessary to do a good job of cross-sectional inspection.

Tap to hear the sound
If it is a relatively good board, you can simply tap it with your fingers. If the sound is a crisp metallic sound, then it is a relatively good board. The fire rating of the Rock Wool Sandwich Panel is Class A, and the fire rating of the polyurethane sandwich panel and Eps Sandwich Panel is B1.


Note the thickness
The thickness of the sandwich panel directly affects the long-term use in the later period. It is necessary to observe the substrate, peritoneum, etc., especially the thickness and quality of the coating, which we cannot ignore. It is necessary to choose a plate with a relatively thick coating and guaranteed quality. Generally, the thickness of the substrate should be about 0.4-0.8MM. If you see the real thing, you should also measure it. The thickness of the finished product is 50mm, 75mm, 100mm, 150mm. The bulk density of the core material is also an important link that affects the quality.

certificate
In fact, as long as it can cooperate with regular manufacturers, the plates sold by the manufacturers need to go through various inspections, and the quality must meet the regulations. Therefore, when purchasing, you can directly check whether it has a certificate of conformity. If you choose a plate from a regular manufacturer, you can not only enjoy a preferential price for direct sales from the manufacturer, but also enjoy good after-sales service.

Now there are many manufacturers supplying plates, and the market quotations and quality of each manufacturer are also different, so it is still necessary to do a good job of quality comparison and price measurement. It is suggested that when purchasing sandwich panels, one must pay attention to its specific quality, and compare the quality of the actual products in order to select high-quality panels.
