Qinhan Precision Industrials Organized Two-day Outward Bound

In order to thank staff’s hard work, and fully mobilize the enthusiasm and initiative of staff, Qinhan Precision Industrials Co.,Ltd organized Chongdugou Scenic two-day outward bound for staff on 4th-5th July. And during the tourist, we also conduct a training activity.
Following the guidance of the tourist guide, staff visited the Golden Rooster River scenic, rainbow waterfall, water curtain Asgard, farming village and other places. In addition, we also held a colorful expand training activities. From this nature tour, the staff felt the magic power of nature, relaxed themselves, enhanced communication with colleagues and strengthen the team spirit and team cohesion.
For over 20 years’ unremitting efforts, Qinhan precision industrials Co.,Ltd has made remarkable achievements. Within advanced technology of cold precision forging, Qinhan has made great contribution to the high-voltage switchgear parts, automotive parts, engine parts, engineering machinery parts’ material saving field. Under the joint efforts of all staff, Qinhan will have an infinitely bright future!

Free Cooling Precision AC Finished For Russian Client

In industrial production, many processes are need industrial water cooling, then we need a cooling manufacturing cooling water of a device. Production of closed center cooling system, it is a circulating cooling water machine, the machine through the compression cooling water circulating water to room temperature below the low-temperature water. Also known as chillers, water-cooled machines.

First, the heating temperature control: temperature range of 40-350 degrees. This machine is also called mold temperature machine, oil temperature machine and water temperature machine. To the terminal equipment to provide a constant heat source.

Second, low temperature control machine: constant temperature range minus 60 ℃ -25 degrees. This machine is divided into cold oil machine, water cooling machines. The above equipment is cooled by the compressor to below room temperature, adjustable temperature control, according to customer requirements to meet the needs of different processes (low temperature chillers, ultra-low temperature freezer). According to the compressor cooling mode is divided into air-cooled and water-cooled. This refrigerator is to provide a constant temperature of the terminal equipment, cold source, to achieve cooling and cooling of terminal equipment, and temperature controllable adjustable.

Third, the room temperature cooling temperature control equipment: temperature range of 25-40 degrees. Closed surface cooler or cooling tower can only cooling to the outdoor temperature, it can not be considered constant temperature machine.

Fourth, industrial air temperature control: temperature range -40 ℃ to 35 ℃. This machine is also called air-conditioners, chillers, industrial air conditioning. This machine is mainly used to cool the equipment cavity. Such as wave soldering, exposure machine.

FIN EVAPORATORS AND CONDENSERS FINISHED FOR SWEDEN CLIENT

Fin evaporators and condensers finished for Sweden client, these are used in telecom cabinet.

The evaporator condenser and the fin evaporator are two important components in the automobile air conditioner, its function is to realize between two different fluids the heat exchange. Therefore, the evaporator and condenser are heat exchangers.

Specifically, in the condenser, the refrigerant delivers heat to the ambient air. The refrigerant flows in the tube, in the heat release process, the refrigerant vapor gradually condenses into refrigerant liquid. While the ambient air is heated, in the evaporator is absorbed by the refrigerant around the cooling air - the heat of indoor air, refrigerant flow in the tube, in the process of endothermic, the refrigerant liquid boiling gasification into the constant cooling Agent vapor. The air is cooled and the temperature is lowered. Under certain conditions, there will be part of the air condensation of water vapor precipitation.

Difference between floating ball valve and the fixed ball valve

The first ,fixed stainless steel floating ball valve and stainless steel ball valves are one of the stainless steel ball valve, stainless steel floating ball valve model is Q41F Q11F or Q61F, etc., stainless steel fixed ball valve model is generally Q47 or Q367F, etc., stainless steel floating ball valve under the general applicable to DN200 caliber, and the engineering stress is less than PN64, fixed and stainless steel ball valve usually applies to diameter greater than DN200, but not limited nominal pressure, stainless steel fixed ball valve ball is fixed, the above is a sphere with a fixed stem, below also have fixed on a fixed axis, two weeks and fixed up and down because of the, so even if the pipe pressure again big, the ball will not move, so is suitable for high pressure large diameter ball valve, as for the floating ball valve, it is only a sphere above the stem set above, when the stem 90 ° rotation, only used to drive the ball spinning effect, so as to open and close the valve, so when the pipeline pressure, the ball feel as imports pressure, pushed to export direction, the ball will be under the action of pressure, close to the outlet valve seat ball valve seat is time, PTFE, of course, is to belong to soft seal, and in the case of low pressure, also can achieve two-way sealed stainless steel floating ball valve, but all the stainless steel fixed ball valve must ensure that the two-way sealed, so that's why the dosage of the stainless steel ball valve in the market, because it is the classification of the lot, according to different environment can choose different types of ball valve.
