Indonesia rack cylinder

(Indonesia rack cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to rack cylinder:

rack 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 rack cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the rack cylinder. c. The rack cylinder seal is extruded, if the O-ring is obviously extruded at the rack cylinder seal, replace the rack cylinder seal.

The machining accuracy of the rack cylinder depends on the level of equipment, production technology and testing means. rack 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 difference between the plunger rack cylinder and the piston rack cylinder is that the piston in the rack cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type rack cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

When the initial action of the rack cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the rack cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

Answers to some questions about rack cylinder:

Injection molding machine die thimble on the side of the feed nozzle, the oil cylinder pull the thimble shift, how to debug the oil cylinder?
The cylinder is connected with the neutron of the injection molding machine, the neutron is retreated after the opening mold is in place, the cylinder taps the thimble plate to the top, and then takes, and the neutron is reset.

How to calculate the cylinder diameter, rod diameter and pressure of the cylinder, and how to output tonnage?
Hydraulic cylinder output force F=PAX10^3(KN) F is the output force (KN), P working pressure (MPa), A is the piston or plunger area of action.
