Threaded seals on the suction sewage truck generally has two forms, one is the thread connection gasket seal, one is filled with thread filling economy seal, both for small diameter threaded connections sealed occasions. Threaded electric diaphragm pump gasket gasket seal is a gasket â‘¡ Double-acting cylinder: Alternating gas supply from both sides of the piston in one or two directions Vacuum force pump seal in many forms, to play in the environmental protection industry Important role and performance, the main sealing forms are: oil seal, gasket seal, thread seal, labyrinth seal, packing seal, power seal, the following on the form of these seals are briefly introduced. , While the thread only acts as a compression force. In a well-designed, well-processed, well-assembled, high speed, the labyrinth seal works well. However, in actual application, there are many leaks in the sewage suction truck, so it is not commonly used in the suction sewage truck. Vacuum pump packing seal is the compressive and resilient packing into the stuffing box, rely on gland axial compression into radial sealing force, which play a sealing role. This method of sealing is called packing sealing, which is called packing. Due to the simple structure of the packing seal structure, easy replacement, low price, to adapt to speed, pressure, medium wide and suction sewage truck design is widely used. A gasket seal method. Gaskets are the basic components of centrifugal seals, the use of a very wide range. Gasket selection mainly based on chemical pump delivery media, temperature, pressure and corrosion and other factors. . â‘¢ diaphragm cylinder: diaphragm instead of the piston, only in one direction output force, with a spring reset. It's sealing performance is good, but the trip is short. Sewage suction truck seal is a self-tightening lip seal, its simple structure, small size, low cost, easy maintenance, less torque resistance, both to prevent media leakage, but also to prevent the intrusion of external dust and other harmful substances, But also a certain degree of wear and tear compensation, but impatience high pressure, it is generally used in low-pressure occasions sewage suction car. Sewage suction truck commonly used sealing method, 3, packing seal â‘£ impact cylinder: This is a new type of components. It converts the pressure of compressed gas into kinetic energy of high-speed piston movement (10 ~ 20 m / s) to work. Suction truck cylinder in the use of the need to meet different conditions and requirements in order to carry out the normal use of good preparation before use to ensure that in a certain area can make a significant contribution to the decision to show significant in the industry The performance advantage.
Flexible Diamond Dot Sanding Disc
Diamond Dot Electroplated Abrasives Magentic Disc are precision abrasives products,This product is a thin solid sheet of springy metal, with dots of diamond abrasive electroplated directly to the base sheet.We use 100% diamonds electroplated onto the surface with nickel. This creates a highly durable, rust free disk for all your grinding needs. The back of the disk has a rubberized magnetic applied to it which allows for easy application to the metal wheel head of your grinder.This magnetic system makes changing from one grit to the next extremely easy. Our Diamond dots cannot pull up or fall off to create bare sections or cause cutting or gouging of the material. The thin metal backing helps the abrasive lay flat and produces a even sharp facet or bevel when required and prevents uncontrolled scratching of the finished surface around the area to be worked.Diamond Disk only 1.7mm thickness with magnetic backing, It easily rectify the distortion of disc and flat attach it to plates of grinder.
