Common materials of rings and riggings Based on the proper consideration of the use of rings, of course, it is better to choose high quality materials. Therefore, both manufacturers and users attach great importance to this issue. Kosobi is Professional manufacturers, a variety of non-standard specifications can produce, long screw use It does not affect […]
Classification of hydraulic valves According to different classification methods, hydraulic valves are divided into many kinds： 1、According to the control method: manual, electric control, hydraulic control, proportional 2、According to function: flow valve (throttle valve, speed control valve, shunt valve), pressure valve (relief valve, pressure reducing valve, sequence valve, unloading valve), directional valve (electromagnetic directional valve, […]
Application fields of stamping robot It is an effective method to use stamping robot instead of manual operation to form a fully automatic production line in stamping production. The overall design of the stamping robot should be considered comprehensively, so as to make it simple, compact, easy to operate, safe and reliable, convenient to install […]
Nondestructive testing of welded pipe fittings: NDT Definition of NDT for welded pipe fittings: NDT refers to a testing method for materials or workpieces that does not damage or affect their future performance or use. NDT can find defects in the interior and surface of materials or workpieces, measure the geometric features and dimensions of […]
Tube bending production process At present, there are basically two kinds of pipe bending production processes in China: The first type: small-diameter pipeline, the general outer diameter specification is ≤89mm, and cold bending is usually adopted, which is carried out by manual or numerical control pipe bending machine. After bending, annealing heat treatment is needed […]
How are qualified pipe fittings produced? If the finished pipe fittings are viewed from the outside, it is difficult to distinguish between good and bad quality, which is only known during the use process. Engineering quality pays attention to safety first, and once an accident happens, it will cause irreparable losses. So how are high-quality […]
Principle and classification of check valves Check valve The function of this type of valve is to allow the medium to flow in one direction only, and to prevent the opposite direction. Usually, this kind of valve works automatically, and the valve flap opens under the pressure of fluid flowing in one direction; When […]
What should we pay attention to when using three screw pump? 1. Selection of speed of three screw pump The flow rate of three screw pump has a linear relationship with rotation speed. Compared with the low-speed screw pump, the high-speed screw pump can increase the flow rate and lift, but the power is […]
Characteristics of stainless steel storage tanks: 1. Stainless steel tank has strong corrosion resistance, which is not corroded by residual chlorine in outside air and water. Each spherical tank is subjected to strong pressure test and inspection before leaving the factory, and its service life can reach more than 100 years under normal pressure. 2. […]
Wafer butterfly valve is a widely used valve. According to valve materials and driving forms, wafer butterfly valve can adapt to many different industries. Sealing materials for wafer butterfly valves can be roughly divided into two types: soft sealing type and hard sealing type. Soft seal butterfly valve has excellent performance, but it can not […]
