Pakistan hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(Pakistan single rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）

single rack cylinder are widely used in Pakistan，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed single rack cylinder for customers from Pakistan.

Introduction to single rack cylinder:

The difference between the plunger single rack cylinder and the piston single rack cylinder is that the piston in the single 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 single 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 single 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 single 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.

At the rated pressure, the thrust of the single rack cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the single rack cylinder is related to the diameter of the single rack cylinder, but not to the stroke of the single rack cylinder. Moreover, the larger the single rack cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the single rack cylinder.

The meaning of the single rack cylinder model marked by the single rack cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the single rack cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the single rack cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about single rack cylinder:

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.
