When the sensor's two layers of induction coil are fixed with the bottom of the hydraulic cylinder, the other end of the sensor will enter into the piston rod's internal. The displacement sensor is used to realize displacement closed-loop control. Must ensure that the precise movement of the piston rod, so that the structure of the piston rod and can be connected to produce accurate movement value, when the hydraulic cylinder work, the sensor moves with the induction coil changes, the sensor also followed the magnetic changes.
If the long time in harsh environments, the position of the deviation will be greater, you need to open-loop control. The sensor speed of the detector speed and the working speed of the hydraulic cylinder is synchronized in the resolution of the time must be clear which is their own force, so that you can control the working speed of the hydraulic cylinder.
Hydraulic cylinder with a variety of transmission organizations to match the end of the messy mechanical movement, and then further expand its use of planning, the sensor allows the hydraulic cylinder to run efficiently.
Before the operation to check the hydraulic pump installation is correct, the coupling installation is in line with the requirements, the screw is tightened; whether the oil is full; hydraulic system safety valve is transferred to the required pressure; whether the pump and the inlet and outlet; hydraulic system Of the safety valve is transferred to the required pressure.
The start of the full-speed start is not sharp, should be in the system unloading state jog motor switch several times the air in the pipeline as far as possible to exclude clean after no-load operation, no abnormal phenomenon after 3 minutes gradually loading, loading process should be no Abnormal vibration, noise or leakage, or immediately stop the inspection and analysis.
If the pump should not be long-term release of oil, filled with lower acid value of the oil, exposed coated anti-rust oil, the oil port sealed with a screw plug to prevent pollution. These are through our years of experience using hydraulic cylinder sorting results, applied in practice, but also take a very good results.
The hydraulic cylinder with diesel or kerosene clean, brushing oil after oiled paper wrapped, preferably into the wooden box, stored in a dry non-corrosive environment.
The outer surface of the hydraulic cylinder, the inner surface of a good spray of diesel oil, with a cloth cover the inner layer of a good anti-rust oil coating on the outside, on the dry place where the first clean with diesel, and then coated with a layer of butter inside and outside rust .
Exhaust device adjustment: First, the hydraulic cylinder operating pressure down to (0.5 - 1) MPa or so, and then reciprocate the piston rod, open the exhaust plug to exhaust. Open the way is: When the piston reaches the end of the trip, the pressure increase in an instant turn over the exhaust plug, and in the beginning back immediately before the closure. Exhaust when the exhaust gas, you can hear the sound of booing, then sprayed with white foam color of oil, the air row when the oil emitted was clear color. Can be used to distinguish whether the exhaust completely.
Buffer equipment adjustment: In the case of equipment with adjustable buffer, and the piston in motion, should first save the valve on the smaller flow direction, and then gradually adjust the mouth to save the size, until the requirements to stop.
Hydraulic cylinder to see the various parts: hydraulic cylinder in addition to the above adjustments, but also to see the various seals of the oil spill, and the joint parts of the bolt looseness and other appearance, to avoid the occurrence of accidents.
