    Influence of melt pump operating pressure on sealing performance
    167
    Driving shaft seal is to prevent a large number of melt leakage, for the inlet of a negative pressure melt pump , driving shaft seal also plays a role in preventing outside air into the pump cavity. There are many forms of shaft seal of melt pump. Lantai melt pump drive shaft seal device is mainly composed of shaft sleeve, lubrication spacer ring, sealing filler, labyrinth seal ring. The pressure regulating valve plays a key role in the packing sealing melt pump. When the pressure of the melt pu
    Cause of leakage of seal and end cover of melt booster gear pump

    According to the serious analysis of the causes of the faults and the damage of the spare parts under the on-site maintenance and replacement, Zhengzhou Bart can think of the following reasons: (1) Because of the high assembly accuracy of the melt supercharged gear pump , the clearance between the gear shaft and the sliding bearing is 0.2 mm, while the sliding bearing and the gear shaft rely on the melt material self-lubrication, sliding. The main reason for the sticking resistance is that the w
    Recycling of waste plastics increases the demand for melt pumps
    50
    In recent years, the disposal and recycling of waste plastics have been paid more and more attention by the people and even the world, China is no exception. However, at present, Chinas waste plastic recycling efficiency is not high, waste plastic recycling plants are not many, so that in many parts of the country, the recycled plastic market is still a blank, or another extreme - supply exceeds demand, prices rise again and again. Experts have analyzed that recycled plastics in China has a broa
    How to deal with overload of melt pump motor
    113
    Melt pump in the use of the process will be in one way or another failure and problems, today we do a motor overload problem cause analysis and treatment methods summarized: 1. reason analysis: the proportion of inhaled medium is too large, and the treatment method is to adjust the specific gravity or viscosity of the medium. 2. reason analysis: the outlet filter pressure difference is too big, processing method: check the cleaning outlet filter. 3. reason analysis: motor shaft bending, processi
    Performance advantages of special melt pumps for wood plastic panels

    Analysis of gear selection and heat treatment process for high temperature melt pump manufacturers
    188
    As a professional manufacturer of high temperature melt pump in China, Zhengzhou Bart has the most professional processing equipment and advanced processing technology. Each melt pump equipment provided by Zhengzhou Bart has high standard and high performance. As the core part of high temperature melt pump, gear is very important for the efficient operation of melt pump. Normally, the gears and shafts (or gear shafts) of high temperature melt pumps are mostly Cr-Mo alloy steels with high hardena
    Influence of gear parameters on gear pump efficiency
    110
    The internal leakage of gear pumps directly determines the volumetric efficiency of gear pumps. Through the analysis of the structure of the gear pump, it is found that there are three main ways of internal leakage: (1) through the clearance between the end face of the gear and the side plate; (2) through the radial clearance between the top circle of the gear and the inner cavity of the pump; (3) contact clearance between the gear mesh. The axial clearance between the end face and the side plat
    Precautions for piping design of melt pump
    107
    When designing the melt pump piping , we should pay attention to the following matters: A, reasonable selection of pipe diameter, large pipe diameter, low liquid flow speed, low resistance loss under the same flow, high price and small pipe diameter, will lead to a sharp increase of resistance loss, increase the lift of the high viscosity pump, increase the power of the matching belt, increase the cost and operating cost. B, the melt pump discharge pipe and its pipe joints should take into accou
