Brazil stacker cylinder

(Brazil stacker cylinder,produced by Hengyu Hydraulic Co., Ltd)

stacker cylinder are widely used in Brazil,because of no need for deceleration device,long service life,smooth movement.So our company has designed stacker cylinder for customers from Brazil.

Introduction to stacker cylinder:

The stacker cylinder should be used correctly and maintained regularly. The stacker 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 stacker cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

The internal leakage of the stacker cylinder is an important indicator to measure the quality of the stacker cylinder: the internal leakage of the stacker cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stacker cylinder, so that the stacker cylinder can not accurately and stably stop in a certain position of the stacker cylinder, so it is one of the main indicators of the stacker cylinder.

If the stacker cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the stacker cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow stacker cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the stacker cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the stacker cylinder includes the leakage caused by excessive wear of the stacker cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and stacker cylinder, and the phenomenon of "pulling the stacker cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

When the stacker cylinder needs to be stored for a period of time, please follow the recommended methods: The stacker cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stacker 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 stacker cylinder should not be in direct contact with water vapor for a long time. The stacker cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stacker 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 stacker cylinder Before working, the stacker cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stacker cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about stacker cylinder:

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
