El Salvador sanitation truck hydraulic cylinder

(El Salvador sanitation truck hydraulic cylinder,produced by Hebei Hengyu company)

sanitation truck hydraulic cylinder are widely used in El Salvador,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed sanitation truck hydraulic cylinder for customers from El Salvador.

Introduction to sanitation truck hydraulic cylinder:

When the sanitation truck hydraulic cylinder is customized, if there are high requirements for the quality of the sanitation truck hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the sanitation truck hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the sanitation truck hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

The commonly used buffer structure of the sanitation truck hydraulic cylinder is composed of a piston boss and a sanitation truck hydraulic cylinder head groove. When the piston moves close to the sanitation truck hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

After the sanitation truck hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

The sanitation truck hydraulic cylinder should be vented: when the sanitation truck hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the sanitation truck hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the sanitation truck hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the sanitation truck hydraulic cylinder, the oil is best entered and discharged from the highest point of the sanitation truck hydraulic cylinder. sanitation truck hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about sanitation truck hydraulic cylinder:

What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.

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.
