Turkmenistan hydraulic cylinder,electric lift cylinder manufacturer,electric lift cylinder
(Turkmenistan electric lift cylinder,produced by Hengyu Hydraulic Co., Ltd）
electric lift cylinder are widely used in Turkmenistan，because of long service life，smooth movement，high work efficiency.So our company has designed electric lift cylinder for customers from Turkmenistan.
If it is found that the electric lift cylinder lubrication is poor or the electric lift cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the electric lift cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the electric lift cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the electric lift cylinder center line. In this way, when the piston works in the electric lift cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the electric lift cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When the piston speed of the electric lift cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the electric lift cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
electric lift cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the electric lift cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the electric lift cylinder. c. The electric lift cylinder seal is extruded, if the O-ring is obviously extruded at the electric lift cylinder seal, replace the electric lift cylinder seal.
When the electric lift cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the electric lift cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.
