Technical parameters of flat vise for grinding machine
Surface Grinding Clamping Using Flat-Jawed Vise
Surface grinding is a machining technique utilized to produce flat, thin surfaces on objects made of metal and other materials. When executing a surface grinding job, it is vitally important to properly clamp the part in order to prevent errors, suc......
Working principle and application of submersible pump
Introduction
A submersible pump (or sub pump, electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, ......

Pile foundation displacement treatment
Pile Foundation Displacement Treatment
Pile foundation displacement treatment refers to the application of external forces such as prestressing, jacking and injecting to the pile foundation to eliminate its potential displacement or reduce its displacement within the allowable range. The purpose ......
Straightness measurement
Straightness measurment is essential for many machining and metrology applications. It is used to ensure that a part is within tolerance, as well as to measure the quality and consistency of the part. Straightness measurement is done by using a variety of instruments. These instruments measure dif......
deep compaction
Deep-Crowding Method
Deep-crowding method is a new and more efficient way of extracting patterns from scanned documents that was developed by computer scientists recently. The goal of this method is to quickly identify patterns from large databases of documents. Essentially, it works by using a n......
GB 10868-89 Specifications for Power Station Temperature and Pressure Reduction Valves
1. Introduction
The Power Station Temperature and Pressure Relief Valve (TPRV) is a device used to control and regulate the pressure and temperature of the power station system. It ensures safe operation of the power station systems by preventing over-pressure or over-temperature conditions from......
The role of dry cutting in gear machining
Introduction
Gear cutting is a machining process used to shape and accurately size metal gears. This process has evolved significantly over time from simple manual procedure to highly specialised automated processes. Dry cutting, such as dry hobbing or dry shaping, has become a popular method for......
