Ground source heat pump details

As China's reform and opening up, China's economy and technology have undergone tremendous changes. In many areas have already had some international influence. For example, ground source heat pump, which uses less equipment in people's life, but with the development of industries such as China, the demand for such products is increasing. So how should users understand such products, businesses and how to introduce ground source heat pump and promote such products? Ground source heat pump details 1, heat pump industry development: Ground source heat pump is the use of shallow surface water (such as groundwater, rivers and lakes) and the soil source to absorb solar and geothermal energy, heat pump principle, both heat Cooling efficient energy-saving air-conditioning system. Prospect Industry Research Institute released "China Ground Source Heat Pump Industry Development Feasibility Study Report Prospects" study shows that China's ground source heat pump industry has developed rapidly in recent years, all over the ground source heat pump project continues to increase, not only benefited from China's rich heat Resources, related technologies continue to improve, but also benefit from the pressure of energy-saving emission reduction. This paper mainly analyzes the situation of energy-saving and emission reduction in our country, advantages and development status of ground-source heat pump, and future development prospects. 2, ground source heat pump working principle: In nature, the water always flows from the lower to the lower, the heat is always transferred from high temperature to low temperature. People can use water pumps to pump water from a low point to a high point to achieve the flow of water from low to high. The heat pump can also transfer heat from low to high temperatures. 3, the advantages of ground source heat pump Prospect Industry Research Institute through a comprehensive analysis, that the ground source heat pump mainly has the advantages of energy saving, environmental protection, applicability, economy and flexibility, the specific analysis is as follows: energy saving, environmental protection, applicable Sex. 4, the type of ground source heat pump: open system: is the direct use of water for heat transfer heat pump system. The system should be equipped with sand control, anti-fouling, water purification and other devices. Closed system: It is a closed system that injects antifreeze and exchanges energy with water or soil through a heat exchanger in a closed plastic tube buried in the ground. Closed system is not affected by groundwater level, water quality and other factors. 5, the existing problems: limitations and shortcomings The current lack of ground source heat pump technology is the "soil thermal imbalance" problem. In the south, cooling is the main part, and heat is injected into the ground all year round. In winter, there is a big demand for heating in the north, absorbing a large amount of heat from the soil. After long years of operation, soil temperature will be unbalanced and affect the surrounding ecology. Through the introduction of the above 5, we can already clearly understand the basic situation of ground source heat pump. But for users, the use of such products is not enough to know about these situations. The use of a class of products not only to pay attention to the characteristics of the product, but also pay attention to the actual production needs.

UPE plastic,full name UHMWPE (ultra high molecular weight polyethylene) is a kind of thermoplastic engineering plastic with excellent properties of linear structure, with a molecular weight of more than 1.5 million.mainly have ESD UPE SHEET,CONDUCTIVE UPE.

Small density, good wear resistance, self - lubricity, impact resistance, corrosion resistance and so on.

Advantages:

1. Average molecular weight about 5,000,000 to 9,000,000;

2.The best abrasive assistance of all plastics , which 4 times higher than that of nylon 66 or teflon and 6 times higher than that of carbon steel;

3.Extremely high impact stength ,which is twice as high as PC ,5 times as high as ABS,it also retaines high toughness at liquid nitrogen temperature (-196'C);

4.Low friction coefficient ,lubricity is equal to that of Teflon ;

5.The best impact energy absorption value of all plastics ,with very good sound reduction effect ;

6.High chemical stability ,capable of resisting various types of corrosion and organic media within certain temperature and concentration range;

7.Strong adhensive resistance which is only second to Teflon;

8.UHMW-PE Plastic is safe , healthful and non-toxic and be can used in contact with food and drugs ;

9.Low density than any other thermoplastic ;

10.Excellent electrical insulation and static resistance ,good resistance to high energy radiation;

11.Moderate mechanical strength,stiffness and creep-resistant property'

12.Outstanding machining property ,very low water absorption .

Deficiencies:

Compared with other engineering plastics, UHMW-PE Plastic is resistant to heat resistance, stiffness and hardness, but can be improved by means of "filling" and "crosslinking".

From the point ofheat resistance, the melting point of UHMW-PE Plastic is approximately the same (136 ℃) and ordinary polyethylene, but because of its big molecular weight, melt viscosity high, so the processing difficulty is big.

Applications:

Papermaking industry : suction box boards ,scrapper,molding plate ,beating ,gear .

Mining industry : charging barrel ,abrasive and adhensive -resistant back lining for warehouses.

Chemical industry : acid pump ,fliter plate , worm gear ,bearing .

Food industry :packing machinery parts ,bottle guide ,screw .wear plate ,slide away ,stud weld ,roller and other transmission parts.

Tenxile industry : buffer board

Food processing industry : chopping block ,refrigerating plant

Wharf:anti-collision board

Specification: the thickness of UHMW-PE Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width can exceed 1200mm, and the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 600mm* 1200mm, and the commonly used specification of 10-180mm is 1200*3080mm. UHMW-PE Plastic can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited.

Color: Black and white, can also be made another color, and the color order is 500KG.

Modified varieties: UHMW-PE Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
