New Zealand hydraulic cylinder,track steering cylinder manufacturer,track steering cylinder(New Zealand track steering cylinder,produced by Hengyu Hydraulic Cylinder Factory)
track steering cylinder are widely used in New Zealand,because of no need for deceleration device,long service life,smooth movement.So our company has designed track steering cylinder for customers from New Zealand.
When the initial action of the track steering 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 track steering 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.
The wear of the hard chromium plating layer of the track steering cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
The definition of the minimum stable speed refers to the minimum movement speed of the track steering cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the track steering cylinder that undertakes different work has different requirements for the minimum stable speed.
When the track steering cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the track steering cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil track steering cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical track steering cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the track steering cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.
How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.
The hydraulic cylinder is slow when moving forward and faster when moving back.
If the cylinder is single, it is slow when it is moving forward without the rod cavity, and fast when it is shrinking.
