Britain hydraulic cylinder,constant speed cylinder manufacturer,constant speed cylinder(Britain constant speed cylinder,produced by Hebei Hengyu company)
constant speed cylinder are widely used in Britain,because of simple structure and reliable operation,no transmission clearance,excellent fatigue and impact resistance.So our company has designed constant speed cylinder for customers from Britain.
If it is found that the constant speed cylinder lubrication is poor or the constant speed cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the constant speed cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the constant speed cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the constant speed cylinder center line. In this way, when the piston works in the constant speed cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the constant speed cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The material, shape and compression of the constant speed cylinder seal have a great impact on the service life and work efficiency of the constant speed cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.
The machining accuracy of the constant speed cylinder depends on the level of equipment, production technology and testing means. constant speed cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.
The constant speed cylinder should be used correctly and maintained regularly. The constant speed cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the constant speed cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
