(Bahrain crushing machine hydraulic cylinder,produced by Hengyu Group）

crushing machine hydraulic cylinder are widely used in Bahrain，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed crushing machine hydraulic cylinder for customers from Bahrain.

Introduction to crushing machine hydraulic cylinder:

When the crushing machine hydraulic cylinder is installed, the piston and the crushing machine hydraulic 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 crushing machine hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the crushing machine hydraulic 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 crushing machine hydraulic cylinders, only careful and careful operation can be avoided.

Because of the slightly complex structure of the buffer crushing machine hydraulic cylinder, sometimes there will be problems, such as when the crushing machine hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

crushing machine hydraulic cylinders in series, parallel and series parallel. Series: In the crushing machine hydraulic 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 crushing machine hydraulic 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 crushing machine hydraulic 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 crushing machine hydraulic 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.

crushing machine hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching crushing machine hydraulic cylinder block - fine boring crushing machine hydraulic cylinder block - grinding crushing machine hydraulic cylinder block. The rolling method is: broaching crushing machine hydraulic cylinder block - fine boring crushing machine hydraulic cylinder block - rolling crushing machine hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the crushing machine hydraulic cylinder block is about 1-2 days, rolling 1 meter of the crushing machine hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the crushing machine hydraulic cylinder increases by 25%. If the crushing machine hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality crushing machine hydraulic cylinders, you must take the rolling production process. After the crushing machine hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about crushing machine hydraulic cylinder:

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
