Burma hydraulic cylinder,push bench hydraulic cylinder manufacturer,push bench hydraulic cylinder(Burma push bench hydraulic cylinder,produced by Hebei Hengyu company)
push bench hydraulic cylinder are widely used in Burma,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed push bench hydraulic cylinder for customers from Burma.
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.
Causes and countermeasures of oil push bench hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the push bench hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the push bench hydraulic cylinder is visibly scarred, the push bench hydraulic cylinder must be replaced. It can be pressurized at one end of the push bench hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most push bench hydraulic cylinder piston drift may not come from the push bench hydraulic cylinder, the above method to determine the push bench hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
When using the push bench hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the push bench hydraulic cylinder block. If the push bench hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the push bench hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the push bench hydraulic cylinder, so that the working efficiency of the push bench hydraulic cylinder is reduced.
When the oil pressure of the push bench hydraulic cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.
What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.
Two cylinders in parallel, how to solve the synchronization problem?
The following methods can be used to achieve parallel cylinder synchronization: 1, rigid mechanical synchronization. 2. The throttle valve or speed regulating valve is used in the circuit to adjust the synchronization. 3, the two cylinders use independent quantitative pump oil supply to achieve synchronization. 4. Synchronous motor is used in the loop to realize cylinder synchronization. 5, using the position sensor to measure the stroke position and control the cylinder synchronization through the electrical system.
