If people are looking for those heavy-duty pressure washers, then they should choose those industrial washing machines. This type of washing machine can be used for those who require greater and heavier power. There are certain types of jobs that require this powerful washing machine, such as cleaning chemicals and oil spills. It is important to remember that this type of washing machine needs to be installed by a professional manufacturer to make sure everything is in the right place.

Don't waste your time and start helping to protect the environment in your own home. Owning a power washer pump can definitely save more time and energy for many generations in the future.

Molding usually uses polypropylene, polyethylene, and acrylonitrile butadiene styrene . Because they are cheap and useful camparing with other kinds. The stuffs used should be determined by the product itself and its purpose.

An injection mold generally costs depends on a number of factors, including size and complexity, impact the final price. To read more about the cost of injection molding, wecome to contact China FHZ Machinery Co., LTD..

Among the more expensive materials used in plastic injection molding are Polycarbonate, Polysulfone, Teflon, Polyurethane and Acetal. These materials are generally stronger or have special properties that make them suitable for specialized functions. Additives and other components can make these plastics even more durable but do add to the price.

Plastic injection moulds' materials with the lowest cost, generally polypropylene and polyethylene, are incredibly versatile and are used to make everything from milk jugs to car batteries. These are the materials most people use every day and low material costs help make mass production possible.

The cost of the materials used in your project also depends on the design, the materials selected, and the quantity required to complete the project.

There are a wide variety of machines used for injection molding. The cheapest option is a small desktop injection molding machine. Small desktop injection molding machines are the most cost-effective option for producing small quantities of parts. If your project requires large industrial molding machines operated by service providers and large manufacturers, you will have to spend a lot. Unlike small desktop injection molding machines, these large machines require professionals who can operate, maintain, and monitor the machines, which also adds additional costs.

When thinking about what material to use for your plastic injection molding, it’s important to remember that the function of the product should determine the material used. Having an understanding of the options available and the prices associated with those materials will help you to make an informed decision.

The service life of plastic injection molds ranges from hundreds to more than a million times. The service life of plastic injection molds depends on their environment, materials, maintenance, production, design and other factors.

1. Environment. The cleaner the environment, the longer the mold service life. The working conditions of plastic injection molding product will not only seriously affect the service life of the molds, but also the oil stains and other untimely cleaning will corrode the surface of plastic molds. Harsh and dirty environments will shorten the life of molds, while molds used in very clean environments can be used for decades.

2. Materials. Injection molding are susceptible to wear and tear due to their lack of hardness. The material of the mold may vary depending on the details of the injection molding process of the required parts. Harder plastics will last longer than softer plastics. In addition, the machine that makes the mold contains more impurities, which may also interfere with the injection mold itself. The corrosion resistance of the product will be affected to a certain extent.

3. Maintenance. Regular maintenance can improve the durability of the mold. Organizing and arranging personnel for regular maintenance is crucial to the service life of plastic injection molds, and can even extend the service life by several years. Therefore, it is also important to develop the habit of regular maintenance.

4. Operations during production. Premature exhaust, long cooling time, and unhooking pins before the scheduled time are examples of such errors. Excessive force during fixing can easily cause mold deformation. Temperature control during the process can also help extend the life.

5. Mold structure design. Ingenious mold structure design can improve efficiency and thus extend the life of the mold. Designers can also improve the service life of plastic injection molds by avoiding some defects during design.

The improvement of power quality is mainly through power quality equipment and current signal and other parameters in the current transformer detection system, so as to correctly control the power quality problem in real time and improve the environment of the distribution system. 

For capacitor bank, we usually only use a CT mounted on the power side for sampling. 

For SVG / APF, a set (3) CT is required for the three phases of the system, which is usually recommended to be installed on the load side.

Current transformer is an electrical device used for measurement and protection. Its main function is to convert large current into small current to facilitate measurement, control and protection. In practical applications, the secondary side of the current transformer cannot be open-circuited for the following reasons:

1. Principle of electromagnetic induction: The working principle of current transformer is based on the principle of electromagnetic induction, that is, when there is current passing through the primary side, a corresponding electromotive force will be generated on the secondary side. If the secondary side is open-circuited, the electromotive force cannot form a loop, causing the output signal of the transformer to be unable to be transmitted.

2. Magnetic saturation phenomenon: When the primary side current of the current transformer is too large, the magnetic flux on the secondary side will also increase, which may lead to magnetic saturation. Magnetic saturation will cause the measurement error of the transformer to increase and may even damage the transformer. Therefore, in order to ensure the accuracy of measurement and the safe operation of the transformer, the secondary side cannot be open circuit.

3. Thermal stability problem: The iron core of the current transformer will generate heat during operation. If the secondary side is open, the heat cannot be dissipated, which may cause the temperature of the transformer to rise. Excessive temperature will affect the performance and life of the transformer, and may even cause safety accidents such as fires. Therefore, in order to ensure the safe operation of the transformer, the secondary side cannot be open circuit.

4. Protection function failure: The current transformer has a protective function in the power system. When short circuit, overload and other abnormal conditions occur on the primary side, the secondary side will induce corresponding current, thereby protecting the primary side equipment. If the secondary side is open-circuited, this protection function will fail, which may cause damage to the primary side equipment or a safety accident.

5. Measurement error: The measurement error of the current transformer is related to the load on the secondary side. When the secondary side is open circuit, the measurement error will increase because there is no load. In order to ensure the accuracy of measurement, the secondary side cannot be open circuit.

6. Affects the normal operation of the relay protection device: In the power system, the secondary side of the current transformer is usually connected to the relay protection device to protect the primary side equipment. If the secondary side is open-circuited, the relay protection device may not work properly, causing the protection function to fail.

To sum up, in order to ensure the measurement accuracy, safe operation and effectiveness of the protection function of the current transformer, the secondary side cannot be open circuit. In practical applications, it should be ensured that the secondary side of the current transformer is always closed to avoid open circuit. At the same time, attention should also be paid to the selection, installation and maintenance of current transformers to ensure their normal operation in the power system.
