This article mainly introduces:

Libya hydraulic cylinder,displacement sensor cylinder manufacturer,displacement sensor cylinder

(Libya displacement sensor cylinder,produced by Hebei Hengyu company）

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

Introduction to displacement sensor cylinder:

When installing the displacement sensor cylinder, the axial ends of the displacement sensor cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the displacement sensor cylinder, there is axial expansion. If the two ends of the displacement sensor cylinder are fixed, all parts of the displacement sensor cylinder will be deformed. When disassembling the displacement sensor cylinder, it is strictly forbidden to hammer the displacement sensor cylinder and the piston surface, such as the displacement sensor cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

The daily inspection of the displacement sensor cylinder includes: checking the connection of the displacement sensor cylinder and the pipe joint for leaks. Check the displacement sensor cylinder rod for leaks. Check the displacement sensor cylinder connection for leaks. When the displacement sensor cylinder moves, the work is normal and smooth. Whether the displacement sensor cylinder has internal leakage.

When installing the displacement sensor cylinder pipe, the pipe should be cleaned after installation, and should not pass through the displacement sensor cylinder block, and the by-pass pipe must be installed in front of the oil port of the displacement sensor cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the displacement sensor cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the displacement sensor cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

When the displacement sensor 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.

Answers to some questions about displacement sensor cylinder:

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.

How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.
