(Puerto Rico spring return cylinder,produced by Hengyu Hydraulic Cylinder Factory)

spring return cylinder are widely used in Puerto Rico,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed spring return cylinder for customers from Puerto Rico.

Introduction to spring return cylinder:

When the spring return 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 spring return cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the spring return 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.

Do not regularly check the damage of the chrome layer of the spring return cylinder: completely extend the spring return cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the spring return cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the spring return cylinder seal. Welding slag is strictly prohibited on the surface of the spring return cylinder.

spring return cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the spring return cylinder head itself is the guide sleeve of the piston rod, the spring return cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the spring return cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

Answers to some questions about spring return cylinder:

What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.

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.
