(Congo tailboard balance cylinder,produced by Hengyu Hydraulic Co., Ltd）

tailboard balance cylinder are widely used in Congo，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed tailboard balance cylinder for customers from Congo.

Introduction to tailboard balance cylinder:

When the long-stroke tailboard balance cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in tailboard balance cylinder head seal damage, oil leakage, and piston sleep in the tailboard balance cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the tailboard balance cylinder; The piston and the piston rod are connected with a spherical joint.

If the seal of the tailboard balance cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and tailboard balance cylinder, and the phenomenon of "pulling the tailboard balance cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.

tailboard balance cylinder piston rod material introduction: In general, we use 45 steel to produce tailboard balance cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

tailboard balance cylinders in series, parallel and series parallel. Series: In the tailboard balance cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the tailboard balance cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the tailboard balance cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the tailboard balance cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

Answers to some questions about tailboard balance cylinder:

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).
