Vacuum Pump in Plastic Absorbing Machine
Vacuum pump is mainly used in the forming process of plastic absorption. It uses the suction generated by the vacuum pump to heat and soften the plastic absorption material and stick it to the plastic absorption Abrasives so as to shape the products. According to the thickness of materials, there are two main categories: thick material and thin material.
How to choose the suction vacuum pump?
When choosing vacuum pump for plastic suction, it is necessary to select vacuum pump according to specific technology. The following two main parameters are used as reference:
Vacuum degree: The so-called vacuum degree is an expression of the degree of air rarefaction, usually expressed in Papa, millibar Mba, millimeter mercury column mmHg and other units.
After the forming of plastic-absorbing products, most of the product bubbles are caused by the defect of the product because the vacuum degree can not meet the requirements. Compared with products with deep grooves, the vacuum requirement is higher.
Flow: refers to the amount of fluid pumped by a vacuum pump per unit time through a closed pipe or an effective cut-off body, commonly expressed in M3/H, L/S, L/Min.
Vacuum flow rate is an important indicator of suction. When choosing vacuum pump, we should pay attention to the specifications and thickness of the product to calculate the amount of air to be pumped out in an hour or a minute, so as to determine the amount of vacuum pump needed. What kind of vacuum pump should suction industry match?
Plastic Vacuum Pump for notices :
Relative to this kind of cold mechanical equipment, many users often neglect its maintenance. Like other mechanical equipment, vacuum pump needs daily maintenance to better play its performance. We need to pay attention to several points in maintenance.
1. Vacuum pump oil should be replenished in time, and the color of the oil mirror must be replaced if the color becomes black and thick.
2. When abnormal noise occurs in vacuum pump, it is necessary to stop the operation of pump, check the cause of pump noise, and prevent the wear of pump cylinder block.
3. The built-in vacuum pump oil mist separator should be replaced in time. It should be replaced once every 2000 hours to prevent the pump smoking and other phenomena caused by the failure of the oil mist separator.
