- Electromagnetic valve common faults and SolutionsSolenoid valve in the use of the process will be a number of small faults, it is a headache, the following small series for us to sum up some of the common faults of the solenoid valve and the solution.1.Coil short circuit or open circuit:Detection method: the first measurement of the on-off with a multimeter, resistance results tend to be close to zero or infinity, that proves winding short circuit or open circuit. If the resistance measurement results of the normal (probably dozens of European), can not be said coil is without fault, please perform the following final test: a metal rod in the electromagnetic valve coil near put a small screwdriver, then the electromagnetic valve is communicated with the power, if magnetic reflected, so that electromagnetic valve coil is good, otherwise it is bad.Processing method: change the solenoid valve coil.2.Plug / Socket problems:Failure phenomena:If there is a plug / socket type electromagnetic valve and a metal reed socket may problems, plugIndustry News July 19, 2016
- A good way to solve the magnetic separator drum skin abrasionMagnetic drum skin abrasion phenomenon in the work is unavoidable, then when this situation we should do what? Although we were not able to prevent this from happening, but we can control this time. The following small make up to teach you a few strokes!In the magnetic separation machine work, and the collision between the materials is necessary to occur, so the magnetic drum wear is also very easy to happen. When the wear reaches a certain extent will appear worn, so that the pulp will enter magnetic drum can be adsorbed on the surface of the magnetic system, locking will be occurred between the drum skin with the magnetic system, or result in bearing damage when the pulp into the bearing and eventually the whole damage can not work normally.The following methods can be used to alleviate the wear time:1.Cylinder skin wear protection1The cylinder cover with PVC coating, and then PVC adhesive coating, so that the service life of the cylinder can be greatly improved.2.Magnetic system fixIndustry News July 18, 2016

- Advantages and disadvantages of ball valveWith a circular channel for the opening and closing of the ball, the ball with the valve stem rotation to achieve the opening and closing movements of a valve. A ball with a hole is the opening and closing parts of the ball valve, rotating around the axis perpendicular to the channel, but from the channel to produce the effect of closing open. Between the pipeline and equipment, the closure and opening of the medium is the role of the ball valve.Industry News July 11, 2016
- Typical precision forging technologyThe technology of producing products that meet the requirements of the parts in the process of forging and forming, or no longer machining, is called the precision machining. There are two ways to achieve precision forging production: refined blank, blank meets the requirements of precision forging. Precision forging parts or parts, this part of the body by forging and directly, thereby reducing the amount of machine. At present there are many kinds of technology in precision forging. Hot forging, cold forging, warm forging, forging and other composite is divided according to the different forming temperature.Industry News July 04, 2016
- Features stainless steel precision casting processing technologyStainless steel precision casting high mechanical properties than the cast iron is higher, but the cast iron than poor performance. Its high melting point, easily oxidized liquid steel, the molten steel flow is poor, shrink large, stainless steel precision casting is suitable for all types and alloy casting.Industry News June 28, 2016
- Select the Magnetic separator may fall into what errorsMagnetic separator is widely used in the recycling, timber, mining, ceramics, chemical, food and other factories, magnetite, pyrrhotite, roasted ore, ilmenite and other materials suitable for wet magnetic particle size below 3mm election, iron work also for coal, non-metallic minerals, building materials and other materials, is the most widely used one of the highly versatile models in the industry.Industry News June 28, 2016

- The difference between the electric valves and solenoid valvesSolenoid valve is a solenoid magnetic occur attract stretched spring to overcome the pressure of the femoral artery and valve operation after power, simple structure, low price, can only end switch; electric switching valve is divided and Conditioning. Off valves are two type of job that is fully open and fully closed, the control valve is in the above device electric valve positioner, through the valve to the closed-loop conditioning in a dynamically stable position.Industry News June 16, 2016
