Algeria hydraulic cylinder,forklift steering cylinder manufacturer,forklift steering cylinder(Algeria forklift steering cylinder,produced by Hebei Hengyu company)
forklift steering cylinder are widely used in Algeria,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed forklift steering cylinder for customers from Algeria.
The material of the sliding part of the forklift steering cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
forklift steering 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 forklift steering cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the forklift steering cylinder. c. The forklift steering cylinder seal is extruded, if the O-ring is obviously extruded at the forklift steering cylinder seal, replace the forklift steering cylinder seal.
Because of the slightly complex structure of the buffer forklift steering cylinder, sometimes there will be problems, such as when the forklift steering cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.
The internal leakage of the forklift steering cylinder is an important indicator to measure the quality of the forklift steering cylinder: the internal leakage of the forklift steering cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the forklift steering cylinder, so that the forklift steering cylinder can not accurately and stably stop in a certain position of the forklift steering cylinder, so it is one of the main indicators of the forklift steering cylinder.
How to choose cylinder size, pump type, motor power for a 30-ton press?
30 tons = 30,000 kg. It is expected to use a 16 mpa oil pump, then the cylinder area =30000/(160x3.14) and then square, the cylinder bore is 150 mm. Calculated at 500 mm travel per minute, the flow rate per minute is :0.75^2x3.14x5=8.8 liters/minute. Motor power =8.8x16/60=2.355. A 9 L/min, 16 mpa pump is available. Piston diameter 150 mm cylinder. 3 kW motor.
What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
