What is sewage truck

Sewage truck is a new type of sanitation vehicle that collects, transfers and transports sludge and sewage to avoid secondary pollution. The suction truck can self-prime and discharge, with fast working speed, large capacity, and convenient transportation. The  suction sewage truck is suitable for collecting and transporting liquid materials such as manure, mud and crude oil.

The suction truck adopts the domestic technology-leading suction pump vacuum pump, which has a large suction force and long suction stroke. It is especially suitable for the suction, loading, and unloading of sludge in the sewer, especially for sucking sewage mud, silt, stone, and brick. Large objects such as blocks.

Sewage trucks details

The special part of the sewage truck consists of power take-off, drive shaft, vacuum suction pump, pressure tank body, hydraulic part, pipe network system, vacuum pressure gauge, visual fecal window, hand washing device, etc. Pump and high-quality hydraulic system, the tank can be opened later, and the double top is self-unloading. The dirt in the tank can be directly dumped through the back cover, which is of high vacuum (more suction than the suction truck), large tonnage, high efficiency, and wide usage.

The sewage truck has the same principle as the suction truck, but the sewage truck has different uses from the suction truck. The difference lies in the fact that the tank of the suction truck is a circular tank with a tighter structure, which can provide greater suction force under higher pressure and can be used for collecting and cleaning transportation sewage and sludge.

Since the suction hose is always immersed in the liquid surface, the air in the tank, and it becomes thinner and thinner because it is not replenished, so that the pressure in the tank is lower than atmospheric pressure, and the manure, under atmospheric pressure. , through the suction hose into the tank. Or because the siphon is close to the bottom of the tank, when the air is continuously discharged into the manure tank, it is compressed because there is no way out, so that the pressure inside the tank is higher than the atmospheric pressure, and the manure is discharged by the siphon and the suction hose under the action of compressed air. Outside the can.

The suction truck has the characteristics of high suction efficiency, self-priming, self-discharging, and direct irrigation. Pumping manure tank time: ≤ 5min, suction stroke: ≥ 8m. According to the characteristics of long service life, fast working speed, easy operation, and convenient transportation.

1. Environment

Consider the ground and conditions on which the forklift truck will work:
Is the surface smooth or rough?
Indoor, outdoor or both?
How many hours do you use forklift every day?

2. Load/capacity

It would be a big mistake to choose a electric reach forklift whose maximum lifting capacity is lower than your requirement. It's important to see:
What kind of goods will electric reach forklift carry?
What is your average load weight?
What is the maximum weight of the goods you need to lift?
What is the breadth of your goods?

3.Height

The lifting capacity is similar to the maximum load, and you need to ensure that you choose an electric reach forklift that meets your height limit.
What is your usual lifting height?
What is the highest point a forklift truck needs to reach?

4. Fuel types

Compared with other types of forklift trucks, they have longer service life and less consumption. So, with the passage of time, the use of electric reach forklift will get more returns. They also operate very quietly and do not produce emissions, so it is recommended to work indoors or in cold climates.

5. Tire selection

Electric reach forklift has various types of tyres. The most common are solid or pneumatic, but there are also white traceless tires and cushioned tires. Each type of tire has its own specific purpose, suitable for certain environments.

6. Ergonomics

High quality adjustable seats are very important because electric forklift operators sit on their machines for several hours.

Investing in high-quality ergonomics will reduce the likelihood of injury, such as backache, which may be caused by repetitive tasks performed on uncomfortable seats. The design of our electric forklift truck is ergonomically designed to meet your various needs.

3. Sany Quality+ Sin Hanyo Re- manufacture It's more reliable than buying a second line brand new sany concrete pump truck.

The glass plate is an important part of the sany boom pump truck. Although its volume is small, its technical content and processing cost are very high. At present, glass plate can serve for about 30,000 cubic meters of commercial concrete pumping. In order to improve the service efficiency of the arm gantry pump truck, it is very important to take corresponding measures to improve its service life.

Working characteristics of glasses plate

The eyeglass plate is a part of the S-shaped Sany truck mounted concrete pump distribution valve, connecting to the commodity concrete conveying cylinder. Driven by the swinging oil cylinder, the moving part S pipe swings from one commodity concrete cylinder to the other commodity concrete cylinder. The cutting ring vibrates with the S-tube attached to the eyeglass plate. The quick swing of the cutting ring causes intense wear between the eyeglass plate and the pre-mixed concrete. It also bears the impact of cutting off the stones. It can be seen that the eyeglass plate mainly works at room temperature and bears the impact force, shear force and very strong friction.

The main failure modes of eyeglass plate are wear and fracture failure. The wear between the eyeglass plate and cutting ring is abrasive wear. First, the cutting ring and the hole Angle of the eyeglass plate are blunt, and a smaller circular surface wedge-shaped trace is formed. The wear gap increases with the increase of abrasive particle size. When the gap is large to a certain value, the construction will be affected by severe leakage of the slurry. With the increase of pump height, the impact shear of the eyeglass plate will increase, the wear will be more intense, and it is prone to fracture and collapse.

It can be concluded from the above analysis that the surface of the eyeglass plate should not only have high hardness and wear resistance but also have the certain toughness and high fracture resistance.

RF heat sealing equipment uses the friction heat generated on the contact surface of two workpieces to be welded to melt the plastic. Heat energy comes from a certain pressure, a workpiece on another surface with a certain displacement or amplitude reciprocating movement. Once the desired degree of embossing is achieved, the vibration will stop, but there will still be a certain amount of pressure on the two workpieces, so that the just embossed part of the cooling, curing, thus forming a close combination.

Optical cable handover box is a kind of handover equipment which provides end-to-end and jump-over for main layer and distribution layer optical cables. After the cable is introduced into the cable junction box, the main layer cable and the distribution layer cable are connected by jumping fibers after being fixed, terminated and distributed.

The thing placed inside is the end of the optical cable, and the function of the end of the optical cable is to gather two or more signals of the original unrelated computer room together, and then use tail fiber to connect two unrelated cables according to need. Its signal source is the computer room.

Optical intersection boxes collect all optical signals. Optical signals can not be used directly. Photoelectric conversion equipment is needed to convert optical signals into electrical signals. Therefore, if you want to use the signals in optical intersection boxes directly, it is very expensive.

Similar to the optical cabinet, there are also electrical cabinets. The appearance of the electrical cabinet is not different from that of the optical cabinet. However, the signals collected in the electrical cabinet are electrical signals, which can be directly used without conversion. The signal source of the electrical cabinet is also the computer room.

Fiber optic cable junction box is a kind of outdoor connection equipment. The most fundamental requirement for it is to be able to withstand dramatic changes in climate and harsh working environment. It should have the characteristics of waterproof gas condensation, waterproof and dust-proof, pest and rodent prevention, and strong impact damage resistance. It must be able to withstand the harsher external environment. Therefore, waterproof, moisture-proof, dust-proof, impact-proof, pest and rodent-proof requirements are relatively high on the outside of the box; temperature and humidity control requirements are very high on the inside of the box. According to international standards, the highest standard for these projects is IP66. But there are not many cases that can meet this standard.

At present, the main cabinets used in China are KRONE cabinet in Germany, which is made of unsaturated polyester glass fiber reinforced material (SMC) and has good performance in waterproof, moisture-proof and impact-proof. The imitation of domestic reference KRONE boxes is mainly iron metal boxes (generally up to IP65 standard). For metal box, because of its poor performance in waterproof gas condensation, it is doomed not to be widely used and gradually eliminated. Some domestic imitations are quite different from KRONE imported from Germany in terms of waterproof gas condensation and shock resistance due to material performance problems. In addition, due to the poor anti-aging performance of sealant strip, the performance of waterproof and dust-proof is also common. Of course, it is acceptable to reduce performance requirements and investment when the external environment of the installation location of the cable junction box is better.

Nanofiltration (NF) or nanofiltration membrane technology is a relatively recent membrane filtration process used most often with low total dissolved solids water such as surface water and fresh groundwater, with the purpose of softening (polyvalent cation removal) and removal of disinfection by-product precursors such as natural organic matter and synthetic organic matter.

The membranes are key to the performance of NF systems. They are produced in spiral wound, tubular, and hollow fiber formats, from a range of materials, including cellulose derivatives and synthetic polymer.

NF membranes have pore sizes from 1-10 nanometers, smaller than that used in microfiltration and ultrafiltration, but just larger than that in reverse osmosis.

Application range of NF Membrane Technology 

• Desalination & purification
• Dehydrated, concentrated
• Decolor
• Solvent recovery

Background technique of ceramic transformer insulator

Arcing, corona, etc. occur in the device or the end of the hollow core composite sleeve, and the high temperature generated directly acts on the inner wall of the epoxy layer. Or the plasma generated by the arc and the corrosive gas generated by the decomposition of SF6 in the circuit breaker may impinge on the inner wall of the exposed epoxy layer. Polyethylene oxide itself has high temperature ablation resistance, arc resistance and corona resistance, and may cause severe surface ablation and leakage. Therefore, it is necessary to improve the arc resistance of the Hollow & Bushing Insulator.

In the existing science and technology, the fluoroplastic tube is sheathed in the polyethylene oxide/glass fiber composite pipe, thereby utilizing the arc resistance of the fluoroplastic to prevent arc, corona and the like from damaging the inner wall of the hollow composite pipe. However, in this way, its flexibility is poor, the pipe wall is thick, the production is difficult, and the cost is high.

Introduction of Hollow Core Insulators hollow insulator:

Hollow & Bushing Insulator plays an important role in insulation, support, etc. in outdoor power stations, substation and electrical equipment, or as a component of electrical equipment for power equipment. It is usually made of glass fiber hollow-wound tube, upper and lower flanges and silicone rubber shed, which provides support and insulation for wires and electrical equipment, or acts as external insulation for electric equipment, bearing external forces such as bending and stretching.

Structure of hollow porcelain insulator:

The Hollow & Bushing Insulator consists of an insulated mandrel inner cylinder, a tip flange, and a silicone rubber umbrella sleeve. The silicone rubber umbrella sleeve is formed by connecting two or more silicone rubber umbrella sleeve segments, and the connection structure between the adjacent two silicone rubber umbrella sleeve segments is a stepped lap joint structure, which increases the lap joint area. When the silicone rubber umbrella sleeve is subjected to the axial tensile force, the joint strength between the two mold umbrella sleeves is strengthened, the electrical performance of the hollow composite insulator is ensured, and the service life is prolonged.
