(Nigeria roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

roller press hydraulic cylinder are widely used in Nigeria，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed roller press hydraulic cylinder for customers from Nigeria.

Introduction to roller press hydraulic cylinder:

roller press hydraulic 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 roller press hydraulic cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the roller press hydraulic cylinder. c. The roller press hydraulic cylinder seal is extruded, if the O-ring is obviously extruded at the roller press hydraulic cylinder seal, replace the roller press hydraulic cylinder seal.

roller press hydraulic cylinder body inspection: The inner surface of the roller press hydraulic cylinder and the piston seal are the main factors causing the leakage in the roller press hydraulic cylinder, if the roller press hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the roller press hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

roller press hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the roller press hydraulic cylinder head itself is the guide sleeve of the piston rod, the roller press hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the roller press hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

Answers to some questions about roller press hydraulic cylinder:

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
