2018-08-21 How does the melt discharge pump work normally?

How does the melt pump usually work? I believe that the first time to buy a melt pump will be more curious, then with the Haike Xiaobian to learn about the structure of the melt pump and how it works? The melt pump is made up of pump housing, front and rear side cover, gear shaft, sliding bearing and shaft seal. Melt gear pump belongs to positive displacement pump. When it works, it relies on the change of working volume caused by the intermeshing of the main and driven gears to transport the melt. The working volume is composed of the pump body, the cogging of the gear and the bearing with th

2018-08-13 Leakage solutions for chemical pumps during commissioning and normal operation

1. Leakage occurred during commissioning of chemical pumps. The centrifugal force produced by the high speed rotation of the mechanical seal used in the pump after static test will restrain the leakage of the medium. Therefore, after eliminating the failure of the seal between axles and the end cover, the leakage of the mechanical seal is basically caused by the damage of the friction pairs of the dynamic and static rings. The main reasons for the failure of the friction pair seal are: 1) large axial force caused by the evacuation, cavitation and compression during the operation, which separat

2018-08-03 The installation precision of the chemical fiber spinning metering pump

The chemical fiber spinning metering pump is a kind of gear pump, which is mainly used in the field of chemical fiber spinning. The BART melt pump manufacturer provides ZB-U series of chemical fiber spinning metering pump, the working temperature is less than 350 degrees C, and the maximum pressure difference is 40MPa. The chemical fiber spinning metering pump is the heart component of the spinning machine, plays the role of quantitative, constant pressure, and uniform delivery of spinning material (Bart provides the advantages of pressure, wear resistance, long service life and so on). On the

2018-07-25 The advantages and application scope of the melt pump

The ZB-G series melt pump is mainly used for extrusion process of rubber and plastics. It is used in conjunction with extruder and installed at the outlet of extruder. ZB-K series melt pump has the best ability to deal with high viscosity materials, mainly used for polymer and prepolymer transportation. ZB-T series of melt pumps are used in general chemical processes. Advantages: the polymer melt pump ZB series adopts unique volume design, which can provide stable and accurate polymer metering in the condition of constant pressure, temperature and viscosity. Due to the pressure of the ZB melt

2018-07-17 Silicone rubber compound gear pump

n the filtration of silicone rubber compound, the advantage of using a gear pump is significantly larger than that of other rubber compounds, such as EPDM. This is because silicone rubber compounds have very low viscosity, so the pressure increase has a greater impact on the output of the single screw extruder. For example, the test results show that for a specific organosilicon compound, if the pressure is increased from 10 bar to 40 bar, the output of single cycle single screw will be reduced by 50%. Due to the low viscosity of silicone rubber, even under relatively low pressure growth, ther

2018-06-27 The working temperature of the melt pump

All the gears and mating surfaces of the melt pump produced by our company are finely grinded, and the clearance of assembly is strictly controlled to achieve accurate flow. The gear and the pump body use the chromium nickel alloy steel and the high temperature tool steel material according to the ZB-B series of different working conditions; the ZB-H series adopts the imported CPM tool steel or the titanium tantalum alloy material, which is quenched as a whole, the hardness is HRC62-68, and the wear resistance is good. 1. ZB-B series melt pump : working temperature: less than 400 C (750), clea

2018-06-15 How to adjust the sealing system of the melt pump

The new melt pump is 24 h before driving for the first time, and the clearance of the packing gland is generally 9 mm (the factory has been set at the factory); the filler is added to the silicone oil bubble and the silicone oil leakage to the pump is normal. Before the preparation of the grain, the pressure control screw is used to guarantee the full discharge of the waste waste and the speed of the pressure control screw melt pump is controlled at 25 r/min. The pressure control screw rotates inward, pressure to show 0.3-0.5 MPa. When the melt pump reaches the normal production speed, seal ca

2018-06-07 Assembly of melt pump

1. before the assembly of the melt pump , a tank of lubricant, pump body, front and back cover plate, active and driven gear, sealing components and sealing gland should be assembled before lubrication. When assembling, please install the parts one by one in strict accordance with the disassembly sequence of each component, so that all parts are correctly reset. 2. before installing the bolts, melt the threaded parts with high temperature grease and tighten the bolts of the front and rear covers in diagonal way. Always remain free to rotate. If there is any stuck phenomenon, the melt pump must
