2.Stainless steel valve control can use a variety of transmission way, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic actuator, electromagnetic, hydraulic, electric, hydraulic, pneumatic, hydraulic, spur gear, bevel gear drive, etc.;In pressure, temperature or other form under the action of sensor signals, action, according to the requirement of the reservation or not depend on the sensor signals for simple open or shut down, rely on the drive or automatic mechanism makes opening and closing valve for lifting, sliding, place or rotary movement, so as to change the size of the port in order to realize the control function
3.Stainless steel valves are widely used in chemical, petrochemical, petroleum, the papermaking, mining, electricity, liquid gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronic industry, urban construction and other fields.Valve is control unit in the pipeline fluid conveying system, it is used to change the channel cross-section and flow direction of medium, a diversion, globe, adjust, throttle, check, or the overflow pressure relief, and other functions.Used for fluid control valve, from the most simple cut-off valve to extremely complex automatic control system used in all kinds of valves, its various varieties and specifications.Stainless steel valves can be used to control water, steam, oil, gas, mud, all kinds of corrosive medium, liquid metal fluid flow, and radioactive fluid and so on various types of valve working pressure can be from 0.0013 MPa to 1000 MPa ultrahigh pressure, working temperature from 269 ℃ ultra-low temperature to 1430 ℃ high temperature.

CO2 Laser Tube Common Working Problems

Weak output laser power
1. Check if any scratches or dirt on laser tube output lens and the laser tube put on laser tube support at right point (Marked as"suggested support point"on SPT laser tube).
2. Check the output current of laser machine, service voltage, cooling water temperature, cleanness and rate of water flow.
3. Check the cleanness of focus lens and the reflectors on your laser machine, check whether the lens and reflective mirrors get hot or the laser beam is not well aligned.

Laser tube broken or the laser tube ends fallen off
1. Cooling water temperature must be 15 to 25 degrees. The cooling water can be frozen in cold area to cause laser tube broken from inside, so don’t leave any water within the laser tube when temperature is under 0 degree.
2. The 80w co2 laser tube must run under water protection device is on. (To test the tube lights or not with water supplied or not)
3. Check the silicon water pipe is folded or pressed by something.
4. Check if any bubbles in the laser tube.
5. Check whether the cooling water flow rate is normal and the water is circled from low to high.

The above information is provided by SPT, which is the high-tech enterprise being fosued on optical design, manufacture and sales of optical laser products. SPT mainly supplies high quality co2 laser tube, co2 laser lens and mirror, large field size dynamic focus system and 3D laser marking system.

Sacred Sun FCP lead carbon batteries delivered to the roof of the world

Recently, Sacred Sun has successfully won the bidding of China Huadian Corporation (CHD) Tibet renewable energy project with its FCP lead carbon battery energy storage systems, it is the world’s highest and largest solar -diesel micro-grid power plant project and also the key anti-poverty project national supported.

This whole project consist of solar-diesel micro-grid power plant and urban electrical distribution network, it mainly contains 22 MW solar power plant systems, 12MW energy storage bi-directional power inverter, 12 MWh lithium-ion battery pack, 36MWh lead carbon battery group and 2*1500kW diesel generator in detail.

As one of the energy storage solutions leaders, Sacred Sun finally has successfully won this bidding on account of its cutting-edge technology and extensive experience in energy storage solutions. FCP lead carbon battery, a kind of high-end battery produced in china and the advanced technology come from Japanese Furukawa, could operate 4200+ cycles at 70% depth of discharge (DoD), provided that one day one cycle, battery service life could up to 10 years.

Up to now, the materials including FCP energy storage batteries group have already delivered to the Nima county, northwest of Tibet, with the average elevation of 4800m, the annual average temperature 2.3 oC and outdoor extreme minimum temperature lower than 44.6 oC, in which place as we all know with thin air, more wind and snow as well. However, Sacred Sun group, though have undergone sufferings and hardships from severe environment and poor geographical factors, has finally successfully move all the materials to the roof of the world and ready for installation.

Advantages Of Polyamide Thermal Break Over Resin Thermal Break

What's The Difference Between Polyamide & Resin Break
On the left is a technical drawing showing an old resin thermal break barrier on an old Premium fixed lite, next to and surpassed by the polyamide thermally broken profile. The old resin break windows are no longer in production here at Duration Windows. On the right you can see a technical drawing showing a superior polyamide thermal break barrier on a NEW Premium fixed lite. As you can see at a first glance it is a lot larger barrier and has an air gap in it that is similar to the thermal chambers in PVCu windows.
Our aluminium products are all designed for the future. All of our aluminium window and door systems have long since been upgraded to a superior polyamide thermally break barrier as opposed to the old Resin thermal break barrier still used in some window systems. The Polyamide gives at least a 30% improvement to all thermal efficiency and Uw figures on a typical window (1480 x 1230mm). It is these superior polyamide thermally broken aluminium profiles that have enabled us to produce an aluminium “A” Rated window system known as our Premium Plus window system.
Meets the building regulations for NEW BUILD jobs ( now and in october 2010 when more stringent regulations come into force).
Polyamide has a much improved thermal performance i.e. at least a 30% improvement in Uw figures on a typical window (1480 x 1230mm).
Ability to have larger thermal barrier i.e. Polyamide strips of up to 30mm compared with 5/6mm PU resin thermal break.
Dual colour options far easier and cheaper to achieve with polyamide i.e. individual sections can be painted before assembly.
Increased flexibility (Hybrid Sections) - using Premium window sections can be used in a number of combinations.
Polyamide has similar mechanical properties to aluminium i.e. assembled profiles retain their rigidity and have far greater strength.
Has the same heat coefficient as aluminium (melting point, etc.) so it does not crack or distort when subject to extreme cold or heat.
Resin gives off poisonous gases when it melts or ignites in the event of a fire.
Polyamide is a fibreglass compound which means that it can bend without cracking, and can easily produce curved and arched windows. (Resin becomes weakend and tends to splinter under the tensile strain).

Some of the bearings on the introduction

Excavator bearing installation and removal methods should be based on excavator bearing structure, size and with the excavator bearing components with the nature of the decision. Installation, demolition of the pressure should be added directly to the excavator bearing ring tight end surface, not through the excavator bearing rolling body transfer pressure, because it will work in the excavator bearing surface indentation, affecting the excavator bearing normal work, And even make the excavator bearing damage. Excavator bearing cages, seals, dust cover and other parts are easy to deformation, installation or removal of the excavator bearing pressure can not be added to these parts.
Inch bearings with the temperature of the bearing operation began to slowly rise, 1-2 hours to reach a steady state. The normal temperature of the bearing due to the machine's heat capacity, heat, speed and load and different. Importance of inch bearings, which means that when the damage will cause equipment downtime, so this type of bearing should be installed the best temperature detector. Under normal circumstances, the British bearings in the just after lubrication or re-lubrication will have a natural temperature rise and last one or two days.
