Detailed Product Description: | Excavator hydraulic control valve control system 1) Pilot control system in the form of directional control valve has a direct drive type (with handle direct manipulation of the main valve spool, currently less) and a pilot type two. The latter is a pilot with a pilot valve control oil, and then the pilot fluid control valve of the main valve, it is divided into mechanical and hydraulic and electro-hydraulic pilot type pilot type categories. 2) load-sensing control system is essentially a throttle valve system of systems. On the hydraulic excavator, the most commonly used is generally three six-way multi-way valve, fine-tuning the performance of its spool and the poor performance of the combined operation. Since the 1990s, began to use in the hydraulic excavator load sensing control system, which controls whether the flash is open center mode or the median closed manner, are shipped with a pressure compensating valve. The main advantage of using electronic control pressure compensated hydraulic excavator hydraulic system compared with conventional hydraulic systems, load sensing control system are: (1) save energy consumption. Ordinary three six-way valve regardless of dosing pump or variable pump hydraulic excavator small price, there must be a part of the oil spill off via the relief valve, a waste of energy. The variable load-sensing system using ultra-small excavators prices, pump flow all for the load, the pump pressure is greater than the load pressure only 1-3MPa. (2) flow control of high precision, independent of load pressure changes. (3) several actuators can be synchronized motion or movement in some small excavators price ratio and interference. Ordinary three six-way valve system is used in parallel circuit, when several actuators operate simultaneously, the oil flow to the pump output is first low pressure actuators, can not be synchronized. Load sensing control system includes a load sensing control valves and load sensing control pump (or dosing pumps). The main features of 泰安嘉 and Heavy Machinery Co., Ltd. hydraulic excavator integrated control system (1) uses an electronic control pressure compensated hydraulic system load transfer experience. Load-sensing control valve and variable load sensing pump which is controlled by the composition, the pump output flow always flow element (hydraulic cylinders, hydraulic motors) require equal executed. (2) use of electronically controlled power conditioning systems. This is mainly through the computer the engine and hydraulic pump power setting domestic prices of small excavators, determined that the engine throttle opening and the pump displacement. Thus, according to the excavators of different operating conditions, using different engine characteristics and pump characteristic, its characteristic curve is determined by the computer software. (3) use of the electronic control systems of artificial joint control. Because excavator varied job site conditions, complex operation, not yet inseparable from the artificial manipulation, but the electronic control plays an important supplementary regulation. For example, the excavator operator during the entire operation can only manipulate a lever, and the rest is automated interlocking action sports. But with manual priority principle, suspend the operation of the automatic control system manual manipulation. (4) using a handheld terminal fault diagnosis system enables the fault excavator appears timely detection and treatment.泰安嘉 and Heavy Machinery Co., Ltd. Agricultural small excavators prices | Kerry and Heavy Industries (certified) | Yanji mini excavators prices offered by 泰安嘉 and Heavy Machinery Co., Ltd .. Taian Jia and Heavy Machinery Co., Ltd.
