Sichuan Lineng Ultra-High Voltage Equipment Co., Ltd The cold isostatic press structure

Sichuan Lineng Ultra-High Voltage Equipment Co., Ltd the cold isostatic press structure consists of containers, frames, and hydraulic systems; Cold isostatic press is also known as wet bag cold isostatic press.

(1) Cylinder block. It can withstand high pressurecontainer. There are generally two structural forms: one is made up of two layersThe body is hotThe inner cylinder is in a compressed state, and the outer cylinder is in a tensile state, which is only suitable for small and medium-sized isostatic pressing molding equipment; the other is the use of steel wire prestressed winding structure, which has good mechanical propertiesHigh-strength alloy steelAs a simplified core, then use high-strength steel wire to wrap around the outside of the core cylinder according to the prestressing requirements to form a certain thickness of steel wire layer, so that the core cylinder can withstand a large amount of energy Compressive stress。 Even under working conditions, it is not subjected to tensile stress or very small tensile stress, and this container has a high fatigue resistance life and can make containers with larger diameters. The upper and lower plugs of the container are movable, and when pressurized, the upper and lower plugs transmit the force to the frame.

(2) Frame. There are two structural forms: one is a laminated plate structure, which is made of medium-strength steel plates; the other is a winding frame structure, which is made of two semicircular beams and two columns and then wound with high-strength steel wire prestress. This structure has reasonable stress, high fatigue strength, and safe and reliable work.

(3) Hydraulic system. composedLow pressure pump、High pressure pumpand superchargers and various valves. Start to supply oil by a low-pressure pump with a large flow, and then supply oil by a high-pressure pump after reaching a certain pressure. The working medium can be water or oil.
