Latvia hydraulic cylinder,forklift hydraulic cylinder manufacturer,forklift hydraulic cylinder
(Latvia forklift hydraulic cylinder,produced by Hebei Hengyu company）
forklift hydraulic cylinder are widely used in Latvia，because of smooth movement，no need for deceleration device，long service life.So our company has designed forklift hydraulic cylinder for customers from Latvia.
forklift hydraulic cylinder can not drive the load troubleshooting: oil pressure is too low. forklift hydraulic cylinder selection specifications are too small. Leakage in forklift hydraulic cylinder or associated hydraulic system element.
The machining accuracy of the forklift hydraulic cylinder depends on the level of equipment, production technology and testing means. forklift hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.
When the hydraulic oil is not pumped into the forklift hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the forklift hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.
forklift hydraulic cylinder body inspection: The inner surface of the forklift hydraulic cylinder and the piston seal are the main factors causing the leakage in the forklift hydraulic cylinder, if the forklift hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the forklift hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.
What is the function of the forklift truck cylinder and how does it work?
(1) In order to quickly and conveniently pick up the goods, the gantry needs to be tilted forward; In order to prevent the goods from falling, the door frame should be tilted backward to ensure the stability of the goods. The front and back tilt of the frame is accomplished by tilting the oil cylinder. (2) The inclined cylinder is composed of a piston, a cylinder block, a piston rod, an upper cover, a lower cover, a compression nut and a cover female and other main parts. (3) The inclined cylinder has two oil holes that can be interchanged into oil inlet and discharge holes. The cylinder is divided into a front cavity and a back cavity by a piston. The back cavity is filled with high-pressure oil when it tilts forward, and the front cavity is filled with high-pressure oil when it tilts backward.
How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
