FAQ

What kind of material is the hydraulic cylinder of loader?
There are two kinds of damage to the cylinder liner: the abrasion of the cylinder mirror and the corrosion on the outer wall of the cylinder liner. First, the cylinder mirror wear in the following situations: normal wear, abrasive wear, melting wear and corrosion, wear and so on. 1, normal wear, piston ring and cylinder mirror friction caused by, also known as friction and wear. The maximum wear position of the cylinder mirror surface is the position of the piston near the first ring at the top dead point, which often forms an obvious step. Because of this position, the maximum pressure of the cylinder piston ring on the mirror, the upper end of the cylinder with high temperature, abrasion resistance of metals decreased, at the same time, the piston at TDC speed is zero, the oil film is not easy to form, so the lower part of the cylinder wear mirror also larger. Abrasive wear is caused by heavy dust or carbon deposits in the air. Dust is sucked from the upper part, and the carbon deposits are formed in the upper part, so the upper part of the cylinder mirror is relatively worn. When the engine oil is thrown from bottom to top, the hard particles are affected by gravity, so the lower part of the cylinder is more worn. Abrasive wear is characterized by parallel, rectilinear strains of pulling from the cylinder mirror along the direction of the piston.
Can you tell me if the cylinder can be changed into an oil cylinder (low pressure)?
Impossible, otherwise, the volume is not the same.
Compared with hydraulic cylinder and cylinder, what are the advantages of electric cylinder?
Closed loop servo control, the control accuracy of 0.01mm, precision control thrust, increase the pressure sensor, control accuracy of 1%; it is easy to connect with PLC and other control systems to achieve high-precision motion control. Low noise, energy saving, clean, high rigidity, shock resistance, long life, simple operation and maintenance. The electric cylinder can be no trouble in the abominable environment, and the protection grade can reach IP66. Long term work, and achieve high strength, high speed, high precision positioning, smooth movement, low noise. Therefore, it can be widely used in the paper industry, chemical industry, automobile industry, electronics industry, machinery automation industry, welding industry, etc..Low cost maintenance: electric cylinder in complex environment, only need regular grease lubrication, no wearing parts need maintenance, replacement, will be compared to hydraulic system and pneumatic system to reduce a large number of after-sales service costs.The best substitute of the hydraulic cylinder and the cylinder of the electric cylinder can completely replace the hydraulic cylinder and the cylinder, and the environment is more environmentally friendly, more energy-saving advantages, more clean, easily connected with the PLC control system, to realize the high precision motion control.Configuration flexibility: provide installation and configuration is very flexible, installation of components of the whole series: before the installation after the flange, flange, flange side, rear hinged, trunnion mounting, guide module and servo motor; can be installed, or installed in parallel; can increase all kinds of accessories: limit switch, speed reducer, pre tightening nut you can choose; drive AC brake motor, DC motor, stepper motor, servo motor
For example, I press a workpiece with a hydraulic press, and the pressure gauge shows 0.3MPa. Then I change the cylinder pressure. When I type, I choose the 0.3MPa cylinder instead of the inner diameter of the cylinder.
if you want to change into the cylinder pressure, enough on the line, in addition to consider increasing the oil return pipe of the cylinder, pneumatic actuator only because the system did not return with an air inlet pipe. The trachea.
Can cylinder be used as cylinder, cylinder and hydraulic cylinder, Yantai hydraulic cylinder?
That is, the seals are not the same, the cylinder seals may be less oil than the hydraulic cylinder.
always have hydraulic oil leakage, please expert advice, with what seal can avoid, the best zero leakage.
200 / min work frequency, high viscosity, slow flow, affect operation sensitivity.It is precisely the year that is too low to cause disclosure. Try to increase viscosity properly.This is a contradiction.
Apart from the way they are installed, are their sensors universal? That is, can the induction switches used on the A model cylinder be used on the B model cylinders?!Some cylinders use large ones, but others are very small. Are they interchangeable? That is, if the big induction switch is broken, can it be replaced with a small one?
Are you talking about the magnetic induction switch, only the cylinder with magnetic band can be used?
The difference between gas cylinder and cylinder
The advantages of both gas-liquid pressurized cylinder above two: environmental protection and energy saving, convenient control, adjustment is simple. But the output of travel is limited, suitable for short stroke, large output, and environmental protection and energy saving and low configuration settings.
