Uganda hydraulic cylinder,yg series hydraulic cylinder manufacturer,yg series hydraulic cylinder(Uganda yg series hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
yg series hydraulic cylinder are widely used in Uganda,because of no need for deceleration device,long service life,smooth movement.So our company has designed yg series hydraulic cylinder for customers from Uganda.
After chrome plating of the piston rod of the yg series hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
yg series hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the yg series hydraulic cylinder head itself is the guide sleeve of the piston rod, the yg series hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the yg series hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
The advantages and disadvantages of the yg series hydraulic cylinder: the surface of the yg series hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the yg series 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.
The definition of the minimum starting pressure of the yg series hydraulic cylinder refers to the minimum working pressure of the yg series hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the yg series hydraulic cylinder parts and the size of the sealing friction.
When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.
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.
