Hywell Machinery company proffesional to design and manufacture the Continuous Drying Machine that include DW Hot Air Circulation Belt Drying Machine,Drying Machine,Fruit Drying Machine,Spin Flashing Dryer,Rotary Flash Dryer,Belt Type Dryer, welcome to contact us and we will offer competitive price !
Continuous Drying Machine is heated by means of steam or electric power, and also heated with hot air directly from fuel-& coal-burning hot air furnace. Raw material is fed into the drying machine and moves forward continuously to discharge port . The hot air passes through belt and carried out heat exchange with raw material. Then the damp air is exhausted out through cyclone separator and duster. The dry raw material is discharged through discharge outlet. It iscontinuously and big capacity drying machine.
In addition to Continuous Drying Machine,we also provide fruit drying machine,spin flashing dryer,dry heat sterilization oven,belt type dryer.

The purpose of valve maintenance is to ensure that the valve is perennial clean, well-lubricated, valve complete, the normal operation of the state. First, the valve cleaning the valve surface, stem and stem nut on the trapezoidal thread, stem nut and bracket sliding parts and gears, worm and other components, easy to accumulate a lot of dust. Oil, dirt and other media mess stolen goods, the valve will produce wear and corrosion. Therefore, it is obviously very important to keep the exterior of the valve and the movable parts clean frequently to protect the integrity of the valve paint. Dust on the valve is suitable for brush whisk and compressed air purge; Trapezoidal thread and stitching between swabs are suitable for scrubbing with wipes; Valve greasy dirt and media streaks are suitable for steam purging or even brushing with copper wire brush until processed Surface, with the surface showing metallic luster, the paint surface shows the true color paint so far. Traps should be hand responsible for each class at least once, regularly open the flush valve and the bottom of the dredging valve for flushing, or regular disassembly flushing, so as not to block the valve stolen goods. Second, valve lubrication Trapezoidal thread, stem nut and bracket sliding parts, bearing parts, gear and worm gear, worm and other parts of the engagement with the activities, require good lubrication conditions to reduce friction between each other to avoid mutual wear and tear . Some parts specially equipped with oil cup or nozzle, if damaged or lost in operation, should be repaired with Qi, oil to clear. Lubricating parts should be refueled on a regular basis. Often open, the temperature of the valve is suitable for refueling once a week intervals, not often open, the valve temperature is not high fuel cycle can be longer. Lubricants organic oils, butter, molybdenum disulfide and graphite. High temperature valve is not suitable for use with oil, butter, they will be lost due to high temperature melting, and suitable for injection of molybdenum disulfide and wipe the graphite powder. Lubricated parts exposed to the outside, such as trapezoidal thread, gear and other parts, if the use of grease such as butter, easy to contaminate dust, and the use of molybdenum disulfide and graphite powder lubrication, it is not easy to contaminate the dust, lubrication better than butter. Graphite powder is not easy to apply directly, can be used with a little oil or water blend. Oil seal plug valves should be filled in accordance with the provisions of time, otherwise easy to wear and tear. Third, the valve maintenance Valve in operation, all kinds of valve should be complete, intact. Bolts on flanges and brackets are indispensable. Threads should be undamaged and loose. Tighten the nuts on the handwheel. If it is found to be loose, tighten it in time to avoid wearing the connection or losing the hand wheel and nameplate. Handwheel if lost, not allowed to replace with a live wrench, should be timely and complete. Packing gland does not allow skewing or pre-tightening clearance. On the vulnerable to rain, snow, dust, wind and other dirt contaminated valve environment, the valve stem to install the protective cover. The ruler on the valve should be kept intact, accurate and clear. Valve seals, caps, pneumatic accessories, etc. should be complete and intact. Insulation jacket should be no depression, cracks. Not allowed on the operation of the valve beat, standing or supporting heavy objects, especially non-metallic valves and cast iron valves, but also to prohibit. Stainless Steel Multistage Centrifugal Pump CDL / CDLF is a non-self-priming multistage centrifugal pump with a standard motor. The motor shaft is directly connected with the pump shaft through the pump head shaft coupler. The pull rod bolt fixes the pressure cylinder and the overcurrent unit to the pump Head and out of the water between the pump inlet and outlet in the pump at the same line; the pump can be configured according to the needs of intelligent protection of the pump dry rotation, phase loss, overload and other effective protection. Motor l motor is fully enclosed, air-cooled two-pole standard motor. l Protection class: IP55 l Insulation class: F l Standard voltage, 50Hz: 1 × 220-230 / 240V 3 × 200-220 / 346-380V 3 × 220-240 / 380-415V 3 × 380-415V 60Hz: 3 × 200-230 / 346-400V 3 × 220-255 / 380-440V 3 × 220-227 / 380-480V Keywords: valve
