Summarize the difference between Hitachi 200-2 and 200-3 excavators

I often talk about the difference between consulting Hitachi 200-2 and 200-3, and today I will bring you those things. First of all, we need to know that there are two types of Hitachi 200 excavators: EX200 series and ZAXIS200 series (often referred to as ZX200).

Hitachi used 200 excavator

EX is the name of Hitachi's earlier excavator, and the ZX series is an upgrade of EX. ZX was developed by Hitachi on the basis of improving the reliability of the original EX hydraulic control system. It is a relatively new machine recently. On the basis of EX, the electronic control equipment is simplified, the pump displacement angle sensor is directly discarded, and the main control valve is simplified. Added integrated shuttle valve, electronic diagnosis and storage system. The design of components also strengthened the arm and the walking bracket.

The EX series EX200-2 / 3 are imported. From the connection of the pump and the engine, the EX200-3 has an independent transmission mechanism, and the position of the EX200-2 in the pump and the pump control solenoid valve (high speed) is also different; -3 increase The forearm recovery pressure sensor. PVC and EC controllers can be used universally.

The ZX series includes ZX200 and ZX200-3. Hitachi ZAXIS 200-3 uses a new generation engine OHCR valve engine 122kW (166 PS) / 2,000 min-1 (rpm). Compared with ZAXIS200, the power is increased by 11% and the high-pressure common rail is increased Electronically controlled fuel injection system, cold EGR * system LL.

The above briefly summarizes the difference between Hitachi 200-2 and 200-3 excavators, and there are more details of the differences that can be seen by professional identification. For ordinary users, it is difficult to identify the excavator, so you need a professional People's consulting, China Machinery will always be with you, helping you to choose and buy excavators less obstacles, if you just consider buying second-hand excavators, China Machinery is a professional supplier.
