Sudan hydraulic cylinder,pressure retaining cylinder manufacturer,pressure retaining cylinder(Sudan pressure retaining cylinder,produced by Hengyu Hydraulic Cylinder Factory)
pressure retaining cylinder are widely used in Sudan,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed pressure retaining cylinder for customers from Sudan.
Causes and countermeasures of oil pressure retaining cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the pressure retaining cylinder will lead to premature wear of the piston seal, replace the piston seal; If the pressure retaining cylinder is visibly scarred, the pressure retaining cylinder must be replaced. It can be pressurized at one end of the pressure retaining cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most pressure retaining cylinder piston drift may not come from the pressure retaining cylinder, the above method to determine the pressure retaining cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
When the hydraulic oil is not pumped into the pressure retaining cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the pressure retaining cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.
The commonly used buffer structure of the pressure retaining cylinder is composed of a piston boss and a pressure retaining cylinder head groove. When the piston moves close to the pressure retaining 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.
The meaning of the pressure retaining cylinder model marked by the pressure retaining cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the pressure retaining cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the pressure retaining cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
Do the collecting cylinder, distributing cylinder and distributing cylinder on the organic heat carrier boiler need to be notified separately as the pressure vessel for construction?
Do not need to be installed as a separate pressure vessel to inform, according to the organic heat carrier boiler can be informed. Write a "special equipment installation, renovation and maintenance notice" issued on it.
