How the peristaltic pump for treating wastewater works:
The peristaltic hose pump is like squeezing a fluid-filled hose with a pinch, moving forward with the fluid in the forward tube. The peristaltic hose pump for treating wastewater is also the principle just replaced by the roller. The fluid is pumped by alternating and releasing the elastic delivery hose of the pump. Just like squeezing the hose with two clamps, the negative pressure is formed in the tube and flows accordingly. Hose pump series products are a new type of multi-functional and multi-purpose industrial pumps that absorb foreign advanced technology. The peristaltic hose pump has the functions of no seal, no leakage, strong self-priming ability, simple structure and convenient operation. It is suitable for conveying various viscosity, density, corrosive and abrasive fluid materials. It can be used in petroleum, chemical, water treatment, mining, smelting,, papermaking, ceramics and other industries. The precision of the hose pump regulation is very high and can reach 0.5-1%, which is very beneficial for constant delivery in granulation and coating. After a long period of time and comparison, the products of the pump have met the needs of customers in many aspects such as appearance, precision and durability tests. Now almost all granulator manufacturers and end users are gradually replacing gear pumps with more reliable and cleaner pumps.
Industrial hose pump products are the main equipment for transporting fluid media. Different media concentrations, different pH, particle size and many other factors affect the normal operation of the pump. Pump selection is very important. It affects production costs, labor intensity of workers and other issues, and is directly related to whether production can be carried out normally. Especially in chemical, smelting, mining, and other industries, there are special requirements for conveying, balance, and no leakage, and the selection of pumps is more demanding.

The hose pump is mainly composed of a pump casing, a frame, a wheel, a supporting wheel, a retaining wheel, a hose and a drive. The hose is placed in a U shape in the pump casing. When the power drives the wheel on the frame to rotate, the hose is elastically deformed by the backlog of the wheel, forming a negative pressure slurry at the mouth, and the slurry passing through the wheel is formed from the mouth. The pressure conveying of the slurry works in sequence. Hose pumps are mainly used in long-distance slurry transportation, metering pumping, pressure perfusion, etc. in construction, mining, petroleum, sewage, papermaking, ceramics and other fields. Scope of application of the new type grouting pump: simple structure, when conveying mortar, the mortar is not connected with metal parts, and the wearing parts are relatively simple, mainly pipes, which is convenient. Small size, light weight and easy operation. The cost is low, and it is especially suitable for small-scale engineering construction under the condition of low cost. The grouting pump produced by our company has the advantages of low energy consumption, low vibration, low noise, small volume, high efficiency, reliable performance, convenient pressure and flow adjustment, and long service life.
Industrial hose pumps are grouting equipment for mine shafts, railway roads, hydropower projects, rock and soil slopes, underground engineering, subway and municipal construction, as well as blast furnace gunning and building wall spraying equipment in iron and steel and chemical industries. Industrial hose pumps are mainly used in the construction of railways and highways, water conservancy and hydropower, subways, mine roadways, facilities, underground buildings and emergency rescue. Key projects of industrial hose pump: pipe jacking grouting, bentonite grouting, two-liquid grouting (cement-water glass), foundation treatment sinking, ground sinking, post grouting (opening grouting), high pressure grouting, Secondary grouting, basement waterproof plugging and other projects. It is also a grouting equipment. Why has the industrial hose pump become more and more popular in the market in recent years? Where is the reason? The author believes that the three major advantages have established the market position of the industrial hose pump, making the industrial hose pump a popular choice in the market.

Advantage of peristaltic pump for pumping wastewater:
1. The industrial hose pump is small in size, light in weight (body weight 5kg), easy to carry and simple to operate. Reliable technology, reasonable layout and transportation, can reach 0-50Mpa working pressure within a few seconds, saving time, effort and high efficiency. For gap leakage, honeycomb leakage, and underground water gushing, it can be directly grouted with water to block leakage, and the industrial hose pump slurry can be directly injected into the depths of the cracks.
2. High grouting pressure: The industrial hose pump uses compressed air as the power source, and the transport cylinder and the grouting cylinder have a larger effective area ratio, so that a higher injection pressure can be generated in the cylinder with a smaller air pressure.
3. Wide range of uses: industrial hose pumps can be widely used in water conservancy and hydropower engineering reservoir dam grouting, water tunnel crack plugging, seepage prevention, and dam concrete crack prevention and reinforcement. Cracks, expansion joints, construction joints and layout joints in buildings and underground concrete projects are plugged and sealed. Cracks in the roofing concrete slab, through-wall pipes, corners, leaking water, and plugging with water. Subways, tunnels, culverts, sewage treatment pools, concrete cracks leaking water, water plugging, etc. At the same time, the industrial hose pump for pumping wastewater can also realize the functions of multiple machines, plugging grouting, consolidation grouting, crack repair and strong grouting. Widely used in excavation and construction of roads, bridges, dams, mines, high-rise building foundation engineering and various grouting constructions.
The history of the development of peristaltic pump for treating wastewater. In the early 1980s, due to the rapid development of the rubber and plastics industry, new materials and new hoses with good elasticity and corrosion resistance continued to appear, and various hose pumps also emerged in large numbers. The function and performance of the hose pump are not found in many other types of pumps, so the appearance of the hose pump is quickly accepted in Europe. It is mainly due to not only a wider range of pump type selection for large flow and high pressure, but also to solve many troublesome media processing problems. The structural characteristics and excellent performance of the hose pump determine the wide application range of the hose pump. The pump is also called a hose pump. It uses a roller hose for conveying. Because it only flows in the hose, it has nothing to do with the pump head, and does not produce cross-contamination. At the same time, it has high conveying precision and small shearing effect, so it is widely used in chemical industry , environmental protection, scientific research, beverages, food, printing and other fields. The pump is a section of the pump tube between the two rotating rollers to form a "pillow"-shaped fluid. The volume of the "pillow" depends on the inner diameter of the pump tubing and the geometry of the rotor. The flow rate depends on the product of the speed of the pump head, the size of the "pillow", and the number of "pillows" produced by each revolution of the rotor. The dimensions of the "pillow" are generally constant (except when pumping very viscous fluids).
Due to the development of science, the requirements of numerical control in mechanical manufacturing have become more and more stringent, and numerical control can help mechanical manufacturing products. Therefore, it is necessary to strengthen the solution of numerical control in the mechanical manufacturing industry, so that numerical control can help the development of the mechanical industry and enable the production of good products. Therefore, it is necessary to continuously strengthen the effectiveness of numerical control, and constantly make machinery manufacturing and related, and continue to carry out, so as to make the machinery manufacturing industry continue to develop. It renews the concept of manufacturing automation and extends it to flexibility, intelligence and high integration. Intelligent manufacturing includes intelligent manufacturing and intelligent manufacturing. Intelligent manufacturing can not only continuously enrich the knowledge base in practice, but also have the function of self-learning. It also has the ability to collect and understand information and its own information, analyze and judge and plan its own behavior.
Earlier we talked about the budding stage of the pump industry, which is generally considered to be from 1868 to before 1949. The reason why this period is defined as the budding stage is because in this long period of more than 80 years, there were only 4 professional pump factories. After its establishment in 1949, the domestic national economy has entered a period of economic recovery, and various places have sprung up. By the end of the 20th century and the end of the 1960s, there were 50 professional pump factories in my country, and more than 200 pumps were produced concurrently, with an annual output of pumps. 582,400 units, nearly 1,000 varieties. By the end of the 1970s, there were around 50 to 190. Especially in the last 10 years of the 20th century, pump enterprises developed rapidly, with 1,459 pump manufacturers and companies, with an annual output of 7.3958 million pumps and sales of 12.034 billion yuan. This is what I call the growth stage of the pump industry. When handling abrasive media, a strong comparison in use with other positive displacement pumps shows that hose pumps have the lowest life cycle cost. The price of the hose pump may be more expensive than other positive displacement pumps, but the subsequent downtime, the downtime interval and the purchase cost of ancillary equipment, etc., the hose pump has an overwhelming advantage. Replacing the hose is only half an hour or less of work and can be done on site.
Engineering and construction industry hose pumps are widely used. Special attention:
1. When the pump is working, the inlet and outlet valves should be fully opened, otherwise it will cause the rupture of the hose and the damage of the motor.
2. If the conveyed medium will produce hard sediment, it must be rinsed with clean water before shutdown, otherwise the runner, coupling cracking and motor damage may be caused when the machine is turned on next time!
(1) The power of the pump is very small, only 7kw, and only a small generator can work without power supply.
(2) It is the smallest hose pump in China, and it is a good choice for many narrow constructions.
(3) The pump is light in weight and convenient.
(4) The pump is set high, fully hydraulic operation, high performance, compact structure, low failure rate and long service life.
(5) The price of the pump is affordable, and there are three types of pumps: Microsoft tube pump, micro-stone concrete pump and micro-concrete pump for customers to choose.
(6) The structure adopts automatic air pressure, high working pressure, long pumping distance and high pumping height.
