Vietnam hydraulic cylinder,self-locking hydraulic cylinder manufacturer,self-locking hydraulic cylinder(Vietnam self-locking hydraulic cylinder,produced by Hengyu Group)
self-locking hydraulic cylinder are widely used in Vietnam,because of no need for deceleration device,high work efficiency,excellent fatigue and impact resistance.So our company has designed self-locking hydraulic cylinder for customers from Vietnam.
The advantages and disadvantages of the self-locking hydraulic cylinder: the surface of the self-locking hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the self-locking hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
Before the self-locking hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
Because of the slightly complex structure of the buffer self-locking hydraulic cylinder, sometimes there will be problems, such as when the self-locking hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.
The self-locking hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the self-locking hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The self-locking hydraulic cylinder is basically composed of self-locking hydraulic cylinder and self-locking hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.
How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
