Wuxi City Shi Bang Machinery Manufacturing Co., Ltd. production of hydraulic cylinders, cylinders are mainly used for metallurgy, mining, lifting, transportation, shipbuilding, forging, casting, machine tools, coal, petroleum, chemical, scientific research and military industries. The main products are CD / CG250,350 heavy-duty cylinder, JB / ZQ4395-86 heavy metallurgical cylinder, DG vehicle fuel tank, HSG engine cylinder, wood press plunger cylinder, light rod cylinder and hydraulic system, Precision oil, cylinder steel pipe, piston rod, and so on. In addition, the company to undertake various types of non-standard fuel tanks, cylinders, hydraulic system design and manufacturing, and achieved good reputation in the country with many medium-sized projects with remarkable achievements.
The basic performance parameters of hydraulic cylinders comply with ISO standards and GB standards, installation form and size in line with German steel standards. And REXROTH's CD250, CG250 series, Italy FOOSA's DINTYPE200 / 250 series and the United Kingdom ELRAM's SERIES250 series of products is basically the same. Products at home and abroad have a wide range of applications, easy to exchange.
Induction bearing heater with foreign advanced technology and SKF products compared to the following a little bit:
1. Heating a wide range of workpiece, carrying the weight of, and the heating time is short.
2. Time and temperature control, temperature: 0 ~ 300 ℃, time: 0 ~ 99 minutes.
3. Can be used for heating, demolition of bearings, gears, couplings and other circular parts.
Hydraulic cylinder is the hydraulic energy into mechanical energy, do linear reciprocating motion (or swing movement) of the hydraulic actuator. Its structure is simple and reliable. It is used to achieve reciprocating motion, can be removed from the deceleration device, and no transmission gap, smooth movement, so in a variety of mechanical hydraulic system has been widely used. Hydraulic cylinder output pressure and piston effective area and the pressure difference is proportional to both sides; hydraulic cylinder basically by the cylinder and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. The cushioning device and the venting device are dependent on the particular application and other devices are indispensable.
According to the structure of commonly used hydraulic cylinders, can be divided into three types: sanitation garbage truck hydraulic cylinder in a variety of structural forms, there are a variety of classification methods: According to the movement can be divided into linear reciprocating motion and swing swing According to the structure, it can be divided into piston type, plunger type, multi-stage telescopic sleeve type, rack-and-pinion type and so on. According to the installation form, it can be divided into two types: single acting type and double acting type. For the rod, earrings, feet, hinge axis; according to the pressure level can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.
Piston hydraulic cylinder
Piston hydraulic cylinder can be divided into single rod and double rod type two kinds of structure, its fixed way fixed by the cylinder and piston rod fixed two, according to the role of hydraulic pressure has a single role and double acting type. In the single-acting hydraulic cylinder, the pressure oil is only for a chamber of the hydraulic cylinder, the hydraulic pressure to achieve the cylinder in one direction, the opposite direction by external force (such as spring force, self-weight or external load) to achieve; The role of hydraulic cylinder piston movement in two directions through the two-cavity alternately into the oil, by the role of hydraulic pressure to complete.
Single rod double acting piston hydraulic cylinder schematic diagram. It only has a piston rod on one side of the piston, so the effective area of the two chambers is different. In the same oil supply, the different cavity into the oil, the piston movement speed is different; need to overcome the same load, the different cavity into the oil, the required oil pressure is different, or in the system pressure setting, sanitation Garbage truck hydraulic cylinder in both directions can overcome the different load force.
