Hydraulic jack (Jack0 refers to a jack that uses a plunger or a hydraulic cylinder as a rigid lifting member. The structure of the separate jack includes three types: piston cylinder, plunger cylinder, and swing cylinder.

The piston cylinder and the plunger cylinder realize reciprocating linear motion , Output speed and thrust, the swing cylinder realizes reciprocating swing, output angular speed (rotation speed) and torque. The synchronous jack hydraulic motor realizes the continuous rotary motion, while the hydraulic cylinder realizes the reciprocating motion. It has a compact structure, stable work, and top Large supporting force, self-locking, etc. The supporting capacity of the hydraulic jack is strong, and the supporting force of the heavy hydraulic jack exceeds 100t.

Reduce the frequency

In order to greatly reduce the frequency of hydraulic jack (Jack0 fault), we should pay attention to the following points in use: when hydraulic jack is working, first try to lift a part of the heavy object. After carefully checking that the hydraulic jack is normal, then continue to lift the heavy objects. The electro-hydraulic jack buffer device and exhaust device depend on the specific application, and other devices are indispensable. If the backing plate is found to be uneven and not firm after being compressed Or when the hydraulic jack is inclined. 　　

Relieve the pressure of the hydraulic jack and return it, and handle it in time before operating and controlling again. The hydraulic jack should be wiped clean before use, and all parts should be checked for flexibility and damage. Do not use it when there is a load. Remove the quick connector to avoid accidents and damage to the components. 　　

For heavier objects, multiple jacks are required for lifting, the same model of hydraulic jack should be used, and the total rated lifting weight of each hydraulic jack shall not be less than the equipment borne 1.5 times the gravity

A lot of consumer customers have sent emails saying that the sync jack has been worn out, what causes the sync jack to have this phenomenon, and what to do. Today, the editor will address these questions, simply as Let me introduce you.The screw jack manufacturers in china understand customer needs

Rotary motion

The synchronous jack hydraulic motor realizes continuous rotary motion, while the hydraulic cylinder realizes reciprocating motion. The structure of the separate jack includes three types: piston cylinder, plunger cylinder, and swing cylinder. The piston cylinder and the plunger cylinder realize reciprocating linear motion, output speed and thrust, and the swing cylinder realizes reciprocating swing, and output angular velocity (rotation speed) and torque.

The wear of the synchronous jack is mainly due to the failure of the seals, the wear of the cylinder, the scratches of the inner wall, the corrosion of the inner wall, the scratches of the piston or the piston rod, etc., and the hydraulic equipment (shèbèi). The sealing performance of the actuator pressure cylinder directly affects the performance of the equipment, especially when the sealing performance of a larger hydraulic cylinder is damaged.

To repair or replace parts

It is difficult and costly to repair or replace parts. Separate jacks can be used in combination with two or more or other mechanisms in addition to being used individually. To complete special functions. The hydraulic cylinder is simple in structure and reliable in operation, and has been widely used in the hydraulic system of machine tools. The screw jack manufacturers in china told us so.

Traditional repair method

The traditional repair method is to disassemble the damaged parts and externally repair them, or perform brush plating and overall surface scraping, but the repair cycle is long and the repair cost is high. In view of the above-mentioned problems, the newer modern maintenance method is to use polymer composite materials.

The material's excellent adhesion and good pressure resistance can not only meet the requirements of production and use under the above-mentioned working conditions, but also the operation process is simple and easy, with no thermal influence and no limitation on the coating thickness. At the same time, the coating itself has superior oil resistance, corrosion resistance and self-lubricating function, ensuring the wear resistance after repair, ensuring the company's normal production, and avoiding damage to equipment components.
