Melt production involves the mixing of additives such as color masterbatches, resin blending, and repulverization. The finished melt must be uniform in concentration and temperature. The pressure must be large enough to squeeze out the viscous polymer.
The rubber extruder performs all the above processes through a barrel with a screw and a spiral. The plastic pellets enter the barrel through a real hopper of the barrel, and then are transferred to the other end of the barrel through the screw. In order to have sufficient pressure, the depth of the thread on the screw decreases as the interval to the hopper increases. External heating and internal heat generated by friction between the plastic and the screw soften and melt the plastic. Different polymers and different applications often have different requirements for the design of the extruder.... Menos

...MásPV2R fixed displacement vane pumps are generally forward running and can be installed in reverse as required.
PV2R high-pressure quantitative vane pump precautions and installation dimensions:
1. The double-acting quantitative high-pressure hydraulic vane pump pump shaft is not allowed to directly bear radial and axial forces, so as to avoid abnormal damage to the oil pump.
2. During the installation, the holes and the surface of the shaft to be connected must be carefully wiped to reduce the fretting wear on the shaft end surface of the YB-E high pressure vane pump caused by vibration, so as to maintain the dimensional accuracy of the matching shaft diameter for a long time.
3. Pay attention to distinguish between the oil inlet and the oil outlet. Generally, the oil inlet is large and the oil outlet is small. Do not reverse it. When it is verified that the YB-E high pressure vane pump is turned in the direction of the arrow on the label, the motor can be started.

When encountering the following conditions, what methods should we use to deal with them? The following large hydraulic vane pump factory in China & Zhejiang Yongling Hydraulic Machinery Co., Ltd. will teach you how to take emergency measures against some common faults. In the event of a serious emergency, you should immediately stop the machine to avoid causing more serious injuries .
1: Simple repair
If the vane pump suddenly fails during operation or running, simple repair methods should be adopted to make it reliable to run or operate. The connecting rod bearing is damaged, and the accessories need to be replaced. If it is not available for a while, but the meter is required to work, you can use solder tin to make it work for a short period of time.
Two: Plugging
If the pump is used for a long time, it will cause oil leakage, water leakage and air leakage due to its service life... Menos

Does your child have a healthy sleep? If this is not the case, it may be because your child is either sleeping in the dark or the night light you are using is too bright. Several reports on sleep and healthy sleep habits suggest that light saturation can disrupt or affect the natural sleep cycle, ultimately making it more difficult to stay asleep, wake up completely, or fall asleep completely.
However, many parents want to know how they get their children or babies to receive the right amount of sleep. Fortunately, there are ways to help your child sleep at night. Here are some tips to make your child sleep more effectively:
1 sleep routine
Although younger children will want some light instead of a completely dark room, it can help invest in LED night light, which can be turned off after 30 ~ 60 minutes to save energy and let your child sleep in a completely dark environment . If your child's night light doesn't have a... Menos

How to improve the production quality of plastic bottles? China's professional plastic bottle manufacturer & Ningbo RUICHANG Commodity Packaging CO , Ltd . elaborated the following 4 items:
(1) When designing extruded plastic bottles, if the material is high-density polyethylene or polypropylene, the cross-section of the plastic bottle should be rectangular or oval. For low-density polyethylene or other flexible plastic bottles, the horizontal The cross section is preferably circular. This facilitates the extrusion of the contents from the plastic bottle. The plastic parts used with the plastic bottle mouth are mainly bottle caps and seals. The design of the plastic bottle mouth should focus on how to better fit the plastic bottle mouth with the cap and seal. The bottom of the plastic bottle is the weak part of the mechanical properties of the plastic bottle. Therefore, the bottom of the plastic bottle is generally designed as a... Menos
