Three - way machine manufacturer  

Three - way machine is the production of three - way equipment, but also the trust of new and old customers.  Tee machine is suitable for water expansion and cold extrusion process of metal materials, especially stainless steel pipe, carbon steel pipe, copper pipe and other tee.  The characteristics of the three-way machine is that it can form multiple parts at one time, saving the time of water filling, high efficiency and low energy consumption.  Adopt the extrusion cylinder structure, the extrusion cylinder can be adjusted in a certain range, the process range is wide, the versatility is strong.  The three-way machine adopts PLC control system, which can realize two kinds of technological actions of constant pressure and distance.  Boosting device can be set to produce difficult to form tee.  

Three - way machine each brake wheel pump has a three - way solenoid valve, three - way solenoid valve has three functions of pressure boost, pressure holding and decompression.  Pressure boost process: there is no current flow in the solenoid coil, and the solenoid valve is in the position of pressure boost. At this moment, the main brake pump meets the wheel pump, and the brake fluid from the main brake pump directly flows into the wheel pump. The pressure of the wheel pump varies with the pressure of the total pump.  Pressure holding process: when ABS ECU to the solenoid coil into a small adhere to the current (about half of the large current), the solenoid valve in the adhere to the pressure position, all channels are cut off.  At the moment, the main pump wheel pump and the oil return space are blocked from each other and sealed, so that the brake wheel pump insists on a certain brake pressure.  Decompressor process: when ABS ECU to the solenoid coil through a large current value, the piston moved to the upper end, the main cylinder and cylinder access is cut off, the solenoid valve in the position of decompressor, at the moment the solenoid valve will wheel pump and oil return channel is connected, so that the brake fluid in the wheel pump through the solenoid valve, so that the wheel pump brake pressure quickly reduced.  At the same time, the drive motor starts, the hydraulic pump begins to work, the brake hydraulic flow back to the hydraulic tank after conveying to the master cylinder, ready for the next brake cycle.  Three - way machine three - way solenoid valve is divided into three processes of pressure boost process, pressure holding process and decompression process.
