Self-priming centrifugal pump start and stop the correct method of operation

1, This series of pumps , according to the working conditions of the pump, respectively, using high-quality calcium-based butter and oil No. 10 for lubrication, if the pump with butter lubrication should be regularly filled with grease into the bearing box, the use of oil-lubricated pump. Inadequate, then plus enough.
2, the test sucking every quiet 诘 ⒁ ⒁ He owes 窀 窀 谝 谝 value 纳 纳 纳 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 如 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可? Start running under the circumstances, otherwise the pump can not work, and easy to damage the mechanical seal.
3, check suck manganese 宓 catch case martingale? Knot at the nut loose phenomenon.
4, check the sucking 淖 淖 考 test 欠 裼 裼 ㄗ】 【squid frog? Br>> 5, check v. J mouth pipeline is leak, if leaks, you must try to rule out.
6, the test sucking Mi Sheng Sheng 缍 缍 髦 髦 髦 耐 耐 Xi Xiu grasshopper called unloading ?, 7, open the suction pipe valve, slightly open (do not fully open) the outlet control valve.
(B), start and masterpiece:
1, start the pump, pay attention to the steering of the pump shaft is correct.
2, pay attention to the pressure gauge and vacuum gauge readings. After the start when the pressure gauge and vacuum gauge readings after a period of technical problems, then the pump into the normal oil operations.
3, attention to whether there is no abnormal rotation and vibration.
4, before the pump into the normal operation of oil that self-priming (or stripping) process, special attention should be paid to pump the oil temperature rise idling, if this process is too long, the pump oil? Yu? 5, adjust the outlet control valve, the pressure gauge readings point to the specified area to avoid the pump within the lower limit of the prescribed area to prevent the motor overload due to shaft power is too large, or because The flow is too large and the pump produces cavitation, affecting the normal operation of the pump. Make the pump strong vibration. The range of pressure at which various types of oil are delivered can be found in the "Liquid Pressure Control Range Table".
6, if the pump liquid temperature is too high and cause self-absorption difficulties, then you can temporarily shut down.Using the liquid back to the pump back to the pump or to the pump body plus liquid storage directly to the pump to replenish the liquid. Pump down and then start the liquid can be.
7, the pump in the course of work as a strong vibration and sound, there may be pump cavitation caused by cavitation have two reasons:
First, the pipe inlet flow too large. Second, the suction stroke is too high. When the flow rate is too large, the outlet control valve can be adjusted to increase the pressure gauge readings. When the outlet pipe is blocked, it should be promptly excluded. If the suction stroke is too high, the installation height of the pump may be properly reduced.
8, the pump in the process of work for some reason to stop the pump. Need to restart, the outlet control valve should be slightly open (do not fully closed), so that it is conducive to self-priming process gas discharge from the discharge port, but also to ensure that the pump is lighter Under the load of the start.
9, pay attention to the test? Sri Lanka Scrap waste low-scale Xi Xi ┫ frog? Br /> (c), stop pump:
1, must first close the discharge valve on the pipeline.
2, the pump stopped turning,
3, in the cold season, should? ⒈ Manganese 迥 诘 thumb ⒁ Han oval 岢 sentence 謇 淙 word Yi 诘 is?

Machining Aluminum

Aluminum machining is the use of CNC machining out, including: drilling, boring, cutting, turning, screw. Product material are: aluminum6061,6061-T6,6063,6083,7075.5052,2017 .In the high-speed machining out of the workpiece has a good finish. Aluminum machining product surface treatment has anode, electroplating, sand blasting, laser engraving LOGO, mechanical drawing, rolling flower, according to the requirements of the drawings on the product anode all kinds of colors such as color, black, red, blue, yellow. We have a special inspection department to carry out inspection, to ensure that each size of products meet the requirements of the drawings, machining aluminum(cnc aluminum) is the most common in mechanical processing, low density, not easy deformation, high precision products. So it is widely used in various industries.
