(Kazakhstan series synchronous cylinder,produced by Hengyu Group）

series synchronous cylinder are widely used in Kazakhstan，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed series synchronous cylinder for customers from Kazakhstan.

Introduction to series synchronous cylinder:

series synchronous cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards series synchronous cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the series synchronous cylinder guide is determined by the length of the stroke. Check the strength of series synchronous cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

The series synchronous cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the series synchronous cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the series synchronous cylinder wall due to the stiffness and the weight of the parts, causing scars.

If air enters the hydraulic system, the series synchronous cylinder will not operate normally, 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.

Protection of the series synchronous cylinder surface: During the dismantling process, safety protection should be carried out on the series synchronous cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the series synchronous cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the series synchronous cylinder should be cleaned up in time.

Answers to some questions about series synchronous cylinder:

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.

How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.
