Peru hydraulic cylinder,tailboard balance cylinder manufacturer,tailboard balance cylinder
(Peru tailboard balance cylinder,produced by Hengyu Hydraulic Co., Ltd）
tailboard balance cylinder are widely used in Peru，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed tailboard balance cylinder for customers from Peru.
When installing the tailboard balance cylinder pipe, the pipe should be cleaned after installation, and should not pass through the tailboard balance cylinder block, and the by-pass pipe must be installed in front of the oil port of the tailboard balance cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the tailboard balance cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the tailboard balance cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
Piston tailboard balance cylinder is widely used in hydraulic transmission. When the tailboard balance cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the tailboard balance cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the tailboard balance cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.
The definition of the minimum starting pressure of the tailboard balance cylinder refers to the minimum working pressure of the tailboard balance cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the tailboard balance cylinder parts and the size of the sealing friction.
The piston rod and guide sleeve function of the tailboard balance cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.
