What are the water knife accessories? How to choose?

Water knife accessories refers to all the accessories in the process from the pressurization system to the water knife head, we usually buy the wearing parts in the water knife system, such as: gems, seals, valve bodies and so on. Then let's go to our topic today: the types of water knife accessories and how to choose.

There are two types of water knife accessories, one is the accessories in the new pressurization system, and the other is the accessories of the high-pressure pipeline to the tool head. In order to understand the types of water knife accessories, we must first know the pressurization process of water and the structure of these parts of the pressurization system.

Pressurization of water: First of all, the motor drives the oil to drive the piston to do reciprocating motion, one side input low pressure water output high pressure water, high pressure water through the one-way valve body and high pressure pipeline into the accumulator, when the accumulator and the water knife head line into a large pressure difference, the water will be expelled from the water knife head, forming enough to cut the object of high pressure water (water knife).

The high pressure pipeline plays a vital role in the water knife system, and the damage of the high pressure pipeline is often accompanied by pressure imbalance in addition to leakage. So how to choose the coil? The first is the warranty, which is at least one year. Second: the raw material is better, to choose the whole good material, rather than scrap for welding connection. Third: the manufacturer is very important, to choose a large factory with production qualifications, it is best that the source manufacturer has quality assurance and low price.

Water knife cutting machine high pressure fluctuation how to repair - water knife maintenance technical service

Water knife cutting machine is a kind of cutting equipment commonly used in industrial production, which cuts with high pressure water flow and abrasive mixed flow. However, in the process of use, there are sometimes high pressure fluctuations, which will affect the cutting quality and the stability of the equipment. This paper will introduce the causes and maintenance methods of high pressure fluctuation of water knife cutting machine.

First, the cause of high pressure fluctuation

1, the pressure is unstable: the water pump of the water knife cutting machine is a key component to provide high pressure water flow, if the pump pressure is unstable, it will lead to high pressure fluctuations when cutting. Possible causes include pump wear, seal damage, and pump failure.

2, water flow obstruction: During the cutting process, if the water flow is blocked, it will cause the cutting head to be unable to discharge the water normally, resulting in high pressure fluctuations. Possible causes include cutting head blockage, delivery line blockage, nozzle damage, etc.

3, filter problem: the filter of the water knife cutting machine is used to filter impurities in the water, if the filter is blocked, it will lead to poor water flow and high pressure fluctuations.

4, pressure cylinder problem: the pressure of the cutting head is adjusted by the hydraulic system, if there is a problem with the pressure cylinder, it will lead to unstable pressure, resulting in high pressure fluctuations.

Second, maintenance methods

According to the cause of the high pressure fluctuation, we can take the following maintenance methods to solve the problem.

1, check the pump: First check the working status of the pump to confirm whether there is a fault. If the pump is worn, replace the pump or repair the worn parts. If the seal is damaged, replace it. If the pump fails, it may be necessary to seek professional help to repair or replace it.

2. Clean the water flow channel: clean the cutting head, conveying pipeline and nozzle to ensure smooth water flow. Cleaning agent and high pressure water flow can be used for cleaning. For the case of cutting head and nozzle damage, it is necessary to replace it in time.

3, clean the filter: regularly clean the filter of the water knife cutting machine to ensure that it works normally. Cleaning agents and clean water can be used to remove impurities and blockages on the filter.

4, check the pressure cylinder: check whether the pressure cylinder of the cutting head is working normally. If there is a fault, it may be necessary to seek the help of a professional for repair or replacement.

In addition to the above maintenance methods, it is also necessary to regularly maintain and maintain the water knife cutting machine to extend the life of the equipment. Keep equipment clean and replace wearing parts regularly to ensure the normal operation of the whole system. In addition, when using the water knife cutting machine, the operator should operate in accordance with the requirements of the operation manual to avoid problems caused by improper use.

In SUMMARY:

The high pressure fluctuation of water knife cutting machine may be caused by factors such as pressure instability, water flow obstruction, filter problems and pressure cylinder problems. In order to solve these problems, different maintenance methods can be taken, including checking the pump, cleaning the water flow channel, cleaning the filter and checking the pressure cylinder. At the same time, regular maintenance and maintenance of equipment, reasonable operation of water knife cutting machine, can also effectively prevent and reduce the occurrence of high pressure fluctuations.
