Belarus hydraulic cylinder,lifting platform cylinder manufacturer,lifting platform cylinder

(Belarus lifting platform cylinder,produced by Hebei Hengyu company）

lifting platform cylinder are widely used in Belarus，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed lifting platform cylinder for customers from Belarus.

Introduction to lifting platform cylinder:

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

If it is found that the lifting platform cylinder lubrication is poor or the lifting platform cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the lifting platform cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the lifting platform cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the lifting platform cylinder center line. In this way, when the piston works in the lifting platform cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the lifting platform cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

When the lifting platform cylinder is installed, the piston and the lifting platform cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the lifting platform cylinder head boss is easy to cause scars when it hits the inner surface of the lifting platform cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized lifting platform cylinders, only careful and careful operation can be avoided.

lifting platform cylinder can not drive the load troubleshooting: oil pressure is too low. lifting platform cylinder selection specifications are too small. Leakage in lifting platform cylinder or associated hydraulic system element.

Answers to some questions about lifting platform cylinder:

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
