Nepal hydraulic cylinder,extra high pressure cylinder manufacturer,extra high pressure cylinder

(Nepal extra high pressure cylinder,produced by Hebei Hengyu company）

extra high pressure cylinder are widely used in Nepal，because of simple structure and reliable operation，excellent temperature resistance，clever hydraulic energy conversion.So our company has designed extra high pressure cylinder for customers from Nepal.

Introduction to extra high pressure cylinder:

When the extra high pressure cylinder needs to be stored for a period of time, please follow the recommended methods: The extra high pressure cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the extra high pressure cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil extra high pressure cylinder should not be in direct contact with water vapor for a long time. The extra high pressure cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the extra high pressure cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the extra high pressure cylinder Before working, the extra high pressure cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the extra high pressure cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

The extra high pressure cylinder should be used correctly and maintained regularly. The extra high pressure cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the extra high pressure cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

When the extra high pressure cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the extra high pressure cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil extra high pressure cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical extra high pressure cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the extra high pressure cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

extra high pressure cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the extra high pressure cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the extra high pressure cylinder. c. The extra high pressure cylinder seal is extruded, if the O-ring is obviously extruded at the extra high pressure cylinder seal, replace the extra high pressure cylinder seal.

Answers to some questions about extra high pressure cylinder:

What does cylinder hob125*100 mean?
HOB is a series of hydraulic cylinder products, the use of pressure 14MPA, tie rod structure. 125 refers to the diameter of the cylinder and 100 refers to the stroke. The unit is millimeters.

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.
