Austria hydraulic cylinder,reciprocating cylinder manufacturer,reciprocating cylinder(Austria reciprocating cylinder,produced by Hengyu Hydraulic Cylinder Factory)
reciprocating cylinder are widely used in Austria,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed reciprocating cylinder for customers from Austria.
Because of the slightly complex structure of the buffer reciprocating cylinder, sometimes there will be problems, such as when the reciprocating 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.
When the reciprocating cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
Protection of the reciprocating cylinder surface: During the dismantling process, safety protection should be carried out on the reciprocating cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the reciprocating cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the reciprocating cylinder should be cleaned up in time.
The reciprocating cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure reciprocating cylinder can use 20 steel pipe, and the high pressure reciprocating cylinder can use 45 steel pipe.
How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.
