When you buy a hydraulic jack from a dealer or online, you must not only learn to use it, but also know how to maintain it.

The hydraulic jack manufacturers in china tell us that cleaning the hydraulic jack before use is a very important part.

The purpose of cleaning a jack

The purpose of cleaning the electric jack before operation is to remove welding slag, metal powder, fragments of sealing material, etc. inside the jack, fully keep the inside and outside of the electric jack clean, and reduce unnecessary troubles. The cleaning steps of the electric jack are as follows：

To start cleaning the electric jack is to dismantle all the pipes after pre-installation (test assembly pipe). It should be ensured that a large amount of obvious metal burrs and powder, sand dust, paint, iron oxide, oil stains, cotton yarn, rubber particles and other dirt that can be cleaned are all carefully cleaned, otherwise it is not allowed to perform the first electric jack During the second installation, the cleaning process should be performed according to the instructions given by the hydraulic jack manufacturers in china .

The cleaning time is determined by the size of the electric jack and the required filtering accuracy and the degree of pollution of the jack. Generally, it is 1 to 2 days and nights. When the predetermined cleaning time is reached, it can be based on the various types of impurities filtered in the filter. Quantity, and then determine whether the cleaning work is over.

Second cleaning

The purpose of the second cleaning is to remove the remaining dirt after installation, such as seal fragments, washing oil and anti-rust oil of different quality, and sand washed from the inside of the casting, powder from metal running-in, etc., and then perform the second time A formal system is installed to ensure the smooth and normal operation of the formal adjustment test run

The cleaning time varies according to the complexity of the electric jack and the required filtration accuracy and the degree of pollution of the equipment. When the predetermined cleaning time is reached, the type and quantity of impurities filtered in the filter can be used to determine whether the cleaning purpose is achieved. End the second cleaning work.

Maintenance

In recent years, the application of hydraulic jacks has been very extensive, and this product is also welcomed and recognized by the majority of users, so what should we pay attention to when using this product? Next, follow the editor to find out.

1. 1.The hydraulic jack should be placed flat before use, not tilted, and the bottom should be leveled to prevent the hydraulic jack from tilting or overturning due to the sinking of the foundation or the deviation of the load. A tough pillow or steel plate can be placed on the bottom of the hydraulic jack to expand Pressure-bearing area, so as to avoid accidents caused by sinking or sliding; do not use oily wood or steel plate as a liner to prevent slipping when force is applied, and safety accidents; the position of heavy objects must be safe and solid. Prevent damage to the equipment.
2. 2.Using hydraulic jack of welding jack manufacturers in china, first try to lift a part of the heavy object first, carefully check that the hydraulic jack is normal, and then continue to lift the heavy object. If it is found that the backing plate is not flat or firm or the hydraulic jack is inclined after being compressed, the hydraulic jack must be decompressed and returned, and it can be operated again after timely handling.
3. 3.During the lifting process, safety sleepers should be laid under the hydraulic jacks in time as the weights continue to rise to prevent accidents caused by the tilting of the hydraulic jacks or the sudden drop of the pistons. When lowering the heavy objects, gradually pull out the sleepers. The distance between the sleeper and the heavy object must not exceed the thickness of a sleeper to prevent accidents!

Protection

Speaking of hydraulic jacks, I believe everyone knows something about it. With the wide application of hydraulic jacks, this product has also received more attention from users. The manufacturer will introduce the maintenance precautions of hydraulic jacks to customers.

1. 1.Immersion method: Some small hydraulic jacks are soaked in anti-rust grease. The thickness of the oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease, so that a layer of anti-rust grease is adhered to the surface.
2. 2.Brushing method: When brushing, pay attention to evenly spread on the surface of the hydraulic jack, not to accumulate, but also to prevent leakage.
3. 3.Spray method: some large anti-rust materials are not suitable for oiling by immersion method, generally use about 0.7Mpa pressure filtered compressed air to spray in clean air. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil. This method must adopt perfect fire protection and labor protection measures.

1. Analysis of the composition principle of hydraulic jacks [Abstract] Hydraulic jacks are widely used in various industries due to their simplicity of use. The article briefly introduces the history of hydraulic jacks in order to let readers understand its main development trends and the composition principles of hydraulic jacks of
   hydraulic jack manufacturers in china also made a simple description, in the hope that readers can have a better understanding of hydraulic jacks, and it will be more convenient to use in future projects. Hydraulic jack; working principle; multi-angle With the continuous development of mechanical equipment technology, hydraulic jack equipment technology is also developing rapidly. Nowadays, hydraulic jacks can be seen in many construction sites, such as automobile maintenance, mineral excavation, and oil extraction, which have contributed to the heavy construction work.
