  The flow passage parts of high temperature pump are made of stainless steel (304, 316L), which are widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, national defense and other departments. It is an ideal equipment for conveying flammable, explosive, toxic and precious liquids, and the best choice for creating a leak-free and pollution-free culture workshop.
  
  The normal applicable temperature of the high-temperature pump is less than 100 degrees. If high-temperature medium needs to be transported, it can be customized as high-temperature type, and the applicable temperature can be within 200 degrees. It can also be customized with insulation jacket to keep the high-temperature medium transported.

  In fact, the factors that affect the vacuum degree of vacuum pump are various, including sealing mode, clearance of accessories, material quality and so on. This paper mainly explains the requirements of vacuum pump for lubricating oil.
  
  (1) With appropriate viscosity: the viscosity of oil is too small, the lubricity can not meet the requirements, the sealing is not good, the viscosity is too high, the internal friction is large, the rotor rotation is difficult, the kinetic energy consumption is increased, and the oil temperature is also increased. The increase of oil temperature will accelerate the oxidation deterioration of oil, especially for rotary vane vacuum pump.
  
  (2) Low saturated vapor pressure: the "vapor pressure" index of oil is low, so it is not easy to evaporate under the working conditions of low pressure and high temperature in the vacuum pump, so as to ensure the required vacuum degree.
  
  (3) The oxidation stability is good, and the oil...    less

  When installing the rotary pump, certain rules must be observed: the pump with small displacement (moving plate and fixed piece type) should be fixed on a considerable base, and when installing the pump, it should be considered that the use process is easy to access, so as to observe its working conditions and replace new oil.
  
  Piston pump should be installed on the foundation and fixed with bolts, nuts, washers and lock nuts. After installation, the pump must be cleaned with clean cloth.
  
  Before starting the pump, it must be washed with vacuum oil, and then injected with the required amount of pumping. When the pump motor and circuit connected, must be sure that the motor belt rotation direction is correct.
  
  To do this, the drive belt must be removed from the pulley of the pump, and then the motor is switched on. If the rotation direction of the motor pulley is consistent with the direction indicated by the pointer on the pump cover, it is correct to turn on...    less

  jin wyd1014 Micro air pump

  The essence of vacuum adsorption of micro vacuum pump: after the micro vacuum pump is powered on, the pressure difference between the negative pressure generated at the suction port and the external atmospheric pressure is used to firmly absorb the object through the contact elements such as suction cup, so as to play the role of hanging, fixing and moving objects.
  
  The next process of vacuum adsorption is the release of the object after being absorbed. When it is necessary to release the absorbed object, the pump must be shut down first, and do not continue to vacuum. After the pump is shut down, the object may not fall off immediately, because the pump has a certain pressure holding capacity, and the vacuum will continue to maintain for a certain period of time (the length of time depends on the air leakage of the system).
  
  However, the actual situation is that the current dual-purpose micro air pump, micro vacuum pump and so on, including domestic micro air pump, micro vacuum pump...    less

  Failover refers to that during the normal startup and operation of the slime pump delivery system, the system will automatically enter the failover state in case of any abnormal state of the equipment. At the same time, the sound-light alarm of the system will be started and the LED will indicate "failure". The staff shall overhaul the abnormal equipment. After completion, start the self-test program of the faulty equipment to check whether the fault is eliminated. When the fault is eliminated, the operation button opens the lock and the LED displays "Everything is normal".
  Fault shutdown of coal slime pump delivery system mainly includes:
  1. The vacuum pressure gauge is over the limit
  When the pressure of the vacuum pressure gauge is too high (> 0.04mpa) due to blockage of the oil absorbing filter element, the operating table shall display the word "oil absorbing blockage", and the filter element shall be cleaned or replaced.
  2. Proximity switch fails and stops
  When the...    less
