Speed: The general rules of the cylinder, when the speed exceeds 2m/s, its service life will be affected. When 0.3m/s is used as the stroke end, it is recommended that no buffer mechanism be installed in order to protect the mechanism and safety. In addition, when using the oil return volume of the cylinder, special attention should be paid to the circuit design. Operation at a low speed of 0.5m/min or less will affect the operability (especially vibration). Therefore, at low-speed operation, negotiations should be conducted.
Installation: When installing, ensure that the direction of the connecting rod at the top end of the piston rod should be consistent with the direction of the cylinder head, earring (or intermediate hinge axis), and ensure the straightness of the entire piston rod in the process of advance and retreat to prevent the occurrence of rigid interference, resulting in no Necessary damage.
Exhaust: After starting the hydraulic pump, adjust the system pressure to about 1.0 MPa. Separately control the reversal of the solenoid valve so that oil can be circulated to each branch, and the exhaust valve provided on the pipe can be turned to discharge the gas in the pipe. When the oil continuously overflows, close the exhaust valve. When the hydraulic cylinder exhausts, the exhaust valve on the extended side of the hydraulic pump piston rod can be opened, the solenoid valve is activated, the piston rod moves to discharge air, and when the piston reaches the top dead center, the exhaust valve is closed. Open the other exhaust valve so that the hydraulic cylinder descends out of the air in the rodless chamber. Repeat the appeal exhaust method until the air in the hydraulic cylinder is drained. Without the exhaust valve, loosen the hose fitting on the hydraulic cylinder one-third. After two more cylinder movements, the air was discharged and the cylinders were drained. If air is left in the cylinder, an abnormality occurs due to turbidity when it is rapidly pressurized.
Lubrication: When the cylinder is mounted on the main machine, after checking the oil leakage in the piping part and the guide sleeve in the operation experiment, the earring and the intermediate hinge bearing part should be buttered.
Safety: The hydraulic cylinder cannot be used as an electrode ground to avoid electric shock to the piston rod.
The longitudinal seam between the color steel plate and the color steel plate and the roof seam between the roof and the roof are mainly made of structural waterproof, and the material is supplemented by waterproof. The water in the joint is not used only under the condition of structural waterproofing, but weather in the wind and rain is increased. Between the flanging of the color steel plate and the side wall of the grooving part on the color plate, due to parts processing, construction and installation, etc., it is impossible to completely match, the surface of the color steel plate is very smooth, the friction coefficient is very small, and the rainwater obliquely recoils often. phenomenon. It is necessary for Caigang Machinery to waterproof materials.
The transverse seam between the color steel plate and the color steel plate is lapped by water, and the method of material sealing is lapped. The material is not less than 120mm in length and has the effect of preventing the corrosion of the sealing steel plate in addition to the waterproof function. The connection between the color steel plate and the purlins is usually through the roof connection. This method is simple and easy to construct. However, it is necessary to make penetration holes in the roof. The connection points are exposed to the atmosphere and often suffer from weather and atmospheric erosion. Therefore, it is recommended to use the "concave" concealed connection method when constructing the roof. The roofs formed by the color steel plate have different structural nodes generated according to the shape of the roof. It is not possible to enumerate all the structural nodes here. Flexible treatment based on the above principles can achieve satisfactory results.
Pressure tile machine is mainly used for color steel steel construction enterprises, building material processing enterprises, car panel companies, advertising design companies, highway guardrail production enterprises

Ming Yang teach you to use the cylinder precautions
Antirust: After the cylinder is mounted on the body, if the piston rod is placed in the extended position, the exposed part of the piston rod must be coated with grease.
