ISG series single-stage single-suction vertical centrifugal pump adopts the most advanced hydraulic model by IS centrifugal pump and is designed and manufactured according to international standard ISO2858. It has the advantages of high efficiency and energy saving, low noise, no leakage and easy installation and use. . According to the use of temperature, medium derived from different for hot water, corrosive media and petrochemical products IRG, IHG, YG and other products.
ISG pipeline centrifugal pump is named after its English code (also known as TPG pipeline centrifugal pump), the pump structure and pump making up the principle of composition.
First, the ISG pipeline centrifugal pump ISG, I believe I know a little knowledge of the pump ISG probably know it is a single-stage single-suction vertical pipeline centrifugal pump, but also know that he is made of cast iron, and ISG centrifugal IHG stainless steel pipe centrifugal pump, YG centrifugal pump (some manufacturers also named ISGB centrifugal pump), IHGB stainless steel centrifugal pump (with H, said the pump is stainless steel 202,304, 316,316 L made of other materials, with B that this pump is explosion-proof motor, the same below). Similar to the internal structure of the ISG pump Nomenclature The same as the external shape of the pump is ISW single-stage single suction horizontal pipeline centrifugal pump. As with the external form of the same material or a different motor pump ISWH stainless steel centrifugal pump (and some also write IHW or TPWH).
Second, the ISG pipeline pump in the pipeline is the structure of the pump or pump assembly classification to give it the name, similar to the pipeline pump so named there are pumps, vertical pumps, horizontal pumps, submersible pumps, Submerged pumps, drum pumps, pumps and other tubes.
ISG pipeline pump model meaning
ISG 50 160 (I) A (B)
50 is the pump inlet and outlet nominal diameter (mm)
160 is the nominal diameter of the impeller (mm)
(I) is traffic classification
A (B) is the first cut of the impeller
ISG pipeline centrifugal pump structure
The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearings, seal ring, stuffing box.
1, the impeller is the core part of the centrifugal pump, it is high speed output power, the blades on the impeller play a major role in the impeller assembly before static balance experiment. The inner and outer surfaces of the impeller require smoothness to reduce the frictional loss of water flow.
2, also known as the pump casing, it is the main pump. To support the role of fixed, and with the bearing bracket to connect.
3, the role of the pump shaft is connected by a coupling and motor, the motor torque to the impeller, so it is the main component of mechanical energy transfer.
4, the bearing is set on the pump shaft supporting the pump shaft components, there are two types of rolling bearings and plain bearings. Rolling bearings using butter as a lubricant to the appropriate general size of 2/3 ~ 3/4 Too much heat, too little sound and fever! Sliding bearings are used as a transparent oil lubricant, refueling to the oil level line. Too much oil to bleed along the pump shaft and cheap, too little bearing but also overheating and burn accident! In the process of running the pump bearing temperature up to 85 ℃ generally run at 60 degrees, if high, we must find out the reasons (whether impurities, whether the oil is black, whether the water) and timely treatment!
5, seal ring, also known as leakage ring. The gap between the impeller inlet and the pump casing is too large, causing the water in the high-pressure area of ​​the pump to flow to the low-pressure area through this gap, affecting the output of the pump and reducing the efficiency. The gap is too small will cause the impeller and the pump shell friction wear. In order to increase the backflow resistance to reduce internal leakage, delay the service life of the impeller and the pump housing, the inner edge of the pump housing and the impeller is provided with a sealing ring at the joint of the outer support, and the sealed clearance is maintained at between 0.25 and 1.10mm.
6, stuffing box mainly by the filler, water seal ring, packing tube, packing gland, water seal tube. The purpose of the stuffing box is to close the gap between the pump housing and the pump shaft so that the water inside the pump does not flow outside and the outside air does not enter the pump. Always keep the pump vacuum! When the pump shaft friction with the filler to generate heat will depend on the water seal to live in the water seal ring so that the filler cooling! Maintain the normal operation of the pump. Therefore, during the inspection of the pump running inspection of stuffing box is a special note! Filler needs to be replaced after about 600 hours of operation.
Third, the centrifugal pump in the ISG pipeline centrifugal pump is named according to the principle, the first analogy to explain the meaning of centrifugation, centrifugal is actually the performance of objects inertia, such as water droplets on an umbrella, when the umbrella slowly turns, the water droplets will Follow the umbrella rotation, this is because the friction between the umbrella and water droplets as a centripetal force to the water droplets. But if the umbrella rotates faster, the friction is not enough to make the water drop in circular motion, then the water drop will move away from the umbrella toward the outer edge, just as a rope pulls the stone to make a circular motion. If it is too fast, the rope will Disconnected, the rocks will fly out. This is called Centrifugal. Centrifugal pump is designed according to this principle, high-speed rotation of the impeller blades to rotate the water, the water thrown, so as to achieve the purpose of delivery. Similar to this name are many, such as: diaphragm pump, screw pump, rotor pump, gear pump, vacuum pump.
ISG pipeline centrifugal pump main purpose
ISG pipeline centrifugal pump for conveying water and physical and chemical properties similar to other liquids used for water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler, fire pressurization, long distance transmission, HVAC refrigeration cycle , Bathroom and other hot and cold water circulation booster and equipment support, the use of temperature T
Small Peanut Slicing Pistachio Cutting Cutter Machine:
This chestnut nut cutter machine/pistachio slice cutting machine is based on the original shredder. The size of the cutter can be adjusted to cut out the different specifications of the material. The graded part is matched with sieves of different specifications. The material is graded by sieve to achieve the required size.
How to Use
1. Before starting, first check whether the transmission parts loose, with or without abnormal noise in time to exclude.
2. Connect the power cord with or without damage to electrical leakage phenomenon.
3. After the normal inspection equipment, then start the machine..
4. After drying the material to remove material impurities, to prevent damage to the cutting knife, and then pour the material into the hopper, adjust the hopper gap and the speed of the conveyor belt, feed and cutting material synchronization.
5. According to customer requirements adjust the gap between the upper and lower cutter, cut out the different sizes of granular materials.
