Singapore hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder
(Singapore vehicle hydraulic cylinder,produced by Hengyu Group）
vehicle hydraulic cylinder are widely used in Singapore，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed vehicle hydraulic cylinder for customers from Singapore.
The definition of the minimum starting pressure of the vehicle hydraulic cylinder refers to the minimum working pressure of the vehicle hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the vehicle hydraulic cylinder parts and the size of the sealing friction.
When the vehicle hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the vehicle hydraulic 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.
Because of the slightly complex structure of the buffer vehicle hydraulic cylinder, sometimes there will be problems, such as when the vehicle 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.
vehicle hydraulic cylinder use should try to avoid sealing belt into the vehicle hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the vehicle hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the vehicle hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
How big is the 100t cylinder pump and how big is the motor?
Load is calculated at 15 tons, stroke is calculated at 100 (both take the maximum) 15 tons = 15,000 kg, 15,000/210 bar (21 mpa) =71.42 square centimeters (cylinder area) 71.42/3,14 In the root *2=90,5 the inner diameter of the cylinder can be taken 100 mm. Travel 100 cm, that is, one meter, assuming 10, seconds a back and forth, then it is six times a minute, six meters per minute, then the required flow is,71,42*600 cm (6 meters) =42840 mm =42.84 liters/minute 42.84*21/60=14.9 kilowatts can choose 1450 RPM 4-stage motor 15KW.
Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
