The basic requirements for the drilling machine (1) The refractory bricks are easily clipped in the drill hole in order to reduce the labor intensity of the workers, shorten the processing time and improve the processing capacity. The installation of the fire bricks during drilling must be simple and convenient. Refractory bricks that require drilling, the center of the hole is mostly on the side of the brick and is at a certain angle to the side of the brick. When drilling in a bench drilling machine or a radial drilling machine, since the center of the drill bit is placed vertically, it must be drilled from top to bottom, and the brick must be placed sideways. The side of the firebrick, the side can not be in contact with the drilling platform, only one edge can contact, can not be positioned and clamped directly, there must be a more complex fixture to fix the fire brick. According to the analysis of the refractory bricks to be drilled, the drill centerline is generally at least parallel to the outer surface of one brick. If the drill bit is placed horizontally, the firebrick can be placed flat on the workbench and the firebrick is pressed against the workbench from top to bottom. It can be seen that placing the bit horizontally simplifies the clamping device while allowing the debris generated during drilling to be easily discharged. (2) The drill bit is convenient for cooling and evacuation during drilling. The drill bit uses the cooling water to carry the heat and debris generated when the drill hole is drilled. The best way to pass water is to pass water through the hollow drill bit, that is, to use a hollow spindle or swivel joint, so that the cooling water flows straight through the inside of the bit, through the cutting point, and then along the outside of the drill pipe and the inner surface of the drilled hole. Outflow can fully and effectively play the role of cooling the drill bit and removing the debris. (3) The drill bit feed must have strong adaptability. In order to adapt to the requirement of drilling different fire bricks, the feed speed and feed force of the drill bit should be easily adjusted. The use of a hydraulic system to control the feed of the drill bit ensures that the feed force is constant and that the feed speed is infinitely variable. For different material firebricks, different feedrates can be set, and drill holes with different diameters can be drilled to determine different feed forces.
Drilling machine features and applications Based on the above analysis, the drilling machine should have the following characteristics in the structure: (1) the centerline of the spindle, that is, the drill bit should be kept horizontal; (2) the cooling and chip removal method of the drill's internal water supply; (3) ) The hydraulic system is used to control the bit feed. The horizontal horizontal hydraulic drilling machine developed has effectively solved the problems such as the installation of refractory bricks, the cooling and evacuation of the drill bit, and the control of the feed rate of the drill, improving the drilling accuracy, drilling speed, and the service life of the drill. Compared with bench drilling machines and radial drilling machines, the drilling speed is increased by 2 times and the life of the drill bit is increased by 3 times.
Variable Peristaltic Pumpis a peristaltic dosing pump that can distribute many types of liquids, such as water-based liquid/shampoo/sauce/chemical-based liquid, etc.
The flow rate of the industrial variable speed Peristaltic Pump can be adjusted by the digital knob to adjust the motor speed to achieve the effect of adjusting the flow rate
The liquid only gets in touch with the Peristaltic Pump Tubing, will not cause cross-contamination. it's suitable for Liquid transfer occasions with high cleanliness requirements, Eg. : food/beverage/cosmetic/medical/biopharmaceutical...
For the Peristaltic Pump Tubing, We have different material choices for your various liquids. The standard tube is silicon tubing which conforms to the FDA certificate. Except that we also offer the Saint-Gobain imported tubing, Eg.: Norprene®A-60-F/Norprene®chemical /Pharmed® BPT... Which suitable for various chemical-based liquid.
Suitable for various industrial applications.
