The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the Hose Pump?
The hose pump series of Luoyang Tongrun Info Technology Co., Ltd. is a new type of peristaltic hose pump developed by absorbing advanced foreign technology. It gets rid of the operation mode of traditional pump impeller and shaft seal, and has advantages in the transportation of media with high viscosity, high corrosivity, and large fluid impurities. It is a completely different principle from traditional pumps and has a wide range of applications.
Versatility: The hose pump can be used to continuously transport fluids. Together, it can detect and deal with many troublesome fluid transport problems in time. It can transport sewage, suspended solids, corrosive chemicals, and other questionable fluids, with a flow rate of up to 40 liters per minute. Some common uses are: coal slurry, magma, mud, mortar, slurry, oil, etc. transportation.
Features of hose pump
1. Easy to install, simple to run, and can run continuously for a long time;
2. Choice of various fibers and slurries delivered in the pump, shearing, abrasive or gas-liquid-solid mixture;
3. It can easily corrode fluids in the pump, such as highly viscous, high-density fluids, and pasty fluids;
4. The hose pump does not need to replace the seals, gaskets, impeller rotor, stator or various traditional pump internal parts;
5. The movement of the pump is divided into clockwise rotation without backflow and siphon phenomenon, and has a shut-off valve function; reverse, the fluid can be sent out and sucked back;
6. The pumped fluid is proportional to the speed, which can be accurately measured.
Working principle of hose pump
A special rubber hose with a smooth inner wall and reliable strength is installed inside the pump body. It is rotated and squeezed along the hose by a pair of pressure rollers. This rotation allows the medium to be transported in one direction without backflow. The hose is transporting After the medium is applied, the elasticity of the squeezed hose and the force of the side guide rollers restore the hose to its original shape. At this time, a high vacuum is generated in the hose to suck the medium into the lumen again. The roller is squeezed and discharged from the hose, so that the medium is continuously sucked and discharged.
Advantages of hose pumps
It has an unsealed structure without any leakage or pollution;
Using advanced rolling technology, the pressure roller does not need any lubrication;
Strong self-priming ability and self-cleaning ability, can suck materials positively and negatively; simple hose assembly,
Simple installation and maintenance, low maintenance cost and simple operation;
The flow can be adjusted linearly and has a certain metering function;
It does not cause any blockage in the transportation of liquids with high viscosity and impurities;
The pump has a long service life, high head and high pressure at the pump port.
Parameters of hose pumps:

Researchers at the University of Warwick in the UK have developed a lithium battery technology innovation. Adding graphene beams doubles battery life. By strengthening the structure of the anode with graphene beams, they have found an effective way to replace the graphite in the anode with silicon. Thereby increasing the capacity of the lithium-ion battery and more than doubling the lifespan.
