(Croatia press machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

press machine hydraulic cylinder are widely used in Croatia，because of no need for deceleration device，long service life，smooth movement.So our company has designed press machine hydraulic cylinder for customers from Croatia.

Introduction to press machine hydraulic cylinder:

Repair method of small range wear of oil press machine hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

The press machine hydraulic cylinder should be used correctly and maintained regularly. The press machine hydraulic 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 press machine hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

The coordination of the sliding parts of the press machine hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Under normal circumstances, the press machine hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the press machine hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the press machine hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the press machine hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the press machine hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about press machine hydraulic cylinder:

Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.
