020005 slave 3 rail type hydraulic rock drill hydraulic system program, China Li Huijie mining machinery. The problem of the hydraulic system exposed by the rail type hydraulic rock drill in the actual use process is described. The combination mode of the rock drill and the oil supply pump is expounded, and the design scheme of the hydraulic system of the machine is discussed. The function of the hydraulic system is introduced. The design scheme of the two hydraulic systems is proposed. It is simple and full-featured, compact in structure and convenient in maintenance, improving efficiency and reducing energy consumption. 42 620005294 Rock drilling rig spiral back transformation frame mechanism design magazine, Zhongshi Yanping mining machinery. In 1999, the structural characteristics of the spiral oscillating cylinder and its role on the drilling rig are described. The structural form of the large swing angle spiral oscillating cylinder and the determination and calculation methods of the main parameters are introduced. Several structural types of the back-conversion mechanism are discussed, and it is pointed out that modern rock drilling rigs mostly use composite coordinate-type luffing machines with both oscillating and rotating. 5 2 2 hydraulic rock drill computer system publication, Ridu Bian Yingzhi Industrial Machinery. In 1999, the project relied on the operator's visual sensation to improve the operational economy of the hydraulic rock drill. If the hole is drilled, insert the hole at the bottom of the corner hole. It is displayed in the shape of a drill hole on the display mounted on the trolley. This paper introduces the system's general position detection sensor control system display device office computer device function to automatically search the drilling device hole tail position and so on. 2 Zheng Qiulin hydraulic directional lithotripter 8 only 3, Nipponkou Fushou oyster oil air pressure technology. 1999, 383.l52O urban underground tunnel engineering rock formation excavation operation. Blasting can cause intense vibration and noise. The hydraulic directional lithotripter will replace the blasting operation with a method of high efficiency and low pollution. This 3-8 is composed of a hydraulic pump remote control box hidden in the power assist device. It is a high-quality orientation system developed in cooperation with Russia. 122.5 PCT, the oil pressure of 3 expands the rubber hose inserted into the deep well, and the thrust element acts with a pair of wedges to break the rock face. Explain the 5, the type and specification of the structure of the gravel automatic detection of military workers GJ20005300 millennium, the engineering equipment and equipment, the Chinese engineering equipment research. 2000, 2.18 The preface of the 19992000 yearbook, which introduces the future Royal Armored Bridges and the future armored engineering vehicles of the Australian Rapid Engineers Belgian heavy-duty repair vehicle.

The so-called pressure feedback control can achieve the stepless adjustment of the impact energy of the impactor through the stepless adjustment system pressure, thereby achieving the purpose of reducing the installed capacity of the host such as an excavator. 1 Tengda aperture 127133, 1 claw. There is no internal coupling in the machine, which increases the diameter of the piston and achieves the shortest stroke impact at the same power to ensure that the drill bit is in closer contact with the rock. Structure. Controlled by the road position distributor. The advantage is that the frequency is independent of the speed. 3. The basic functions of Chen Wujicheng mechanical engineering machinery and equipment and its development order and equipment status. The selection of the GJ20005301 combat bridge system, the research of the equipment of the Chinese engineering. 2000, 2. 2127 Carrying capacity erecting speed gram type and width anti-corrosion and reliability as well as bridge system and other weapons and equipment advanced bridge system. Such as the German European Bridge Company
Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services. Angle Valves, Angle Globe Valves, Brass Angle Valve, Zinc Angle Valve ZHEJIANG KINGSIR VALVE CO., LTD. , https://www.kingsir-valve.com
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
