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

Introduction to shearing machine cylinder:

Causes and countermeasures of oil shearing machine cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the shearing machine cylinder will lead to premature wear of the piston seal, replace the piston seal; If the shearing machine cylinder is visibly scarred, the shearing machine cylinder must be replaced. It can be pressurized at one end of the shearing machine cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most shearing machine cylinder piston drift may not come from the shearing machine cylinder, the above method to determine the shearing machine cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

The shearing machine 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 shearing machine cylinder can use 20 steel pipe, and the high pressure shearing machine cylinder can use 45 steel pipe.

When the shearing machine cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the shearing machine cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the shearing machine cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

When the shearing machine cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the shearing machine cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

Answers to some questions about shearing machine 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.

What is the function of the forklift truck cylinder and how does it work?
(1) In order to quickly and conveniently pick up the goods, the gantry needs to be tilted forward; In order to prevent the goods from falling, the door frame should be tilted backward to ensure the stability of the goods. The front and back tilt of the frame is accomplished by tilting the oil cylinder. (2) The inclined cylinder is composed of a piston, a cylinder block, a piston rod, an upper cover, a lower cover, a compression nut and a cover female and other main parts. (3) The inclined cylinder has two oil holes that can be interchanged into oil inlet and discharge holes. The cylinder is divided into a front cavity and a back cavity by a piston. The back cavity is filled with high-pressure oil when it tilts forward, and the front cavity is filled with high-pressure oil when it tilts backward.
