Paper expert Gu Minda: My papermaking raw materials, waste paper accounted for a large proportion, if imported, we have to spend a lot of foreign exchange to buy imported waste paper. Meanwhile, China produced about 14 million tons per year of waste paper recovery rate is very low. Compare the gap can be seen: Japan's waste paper recovery rate is 78%; Germany, 4 million tons of waste paper per year, accounting for 83% of all waste paper; the Finnish city of old newspapers, magazines recovery almost 100% ?
Chinese paper industry, "15" plan put forward for the proportion of waste utilization increased from 41% in 2000 to 48% in 2010, reached 55% in 2015, in which the proportion of domestic waste utilization reached 43%. China's wastepaper recycling uneven development, rapid coastal development. In 2001, the national waste paper pulp accounts for 44% of pulp and paper with the total, net imports of waste paper, domestic waste recovery rate of less than 30%. In recent years, mainly to improve the utilization of waste paper imported wastepaper resolved, the parties concerned should cause attention, we need to increase measures to improve the recovery rate of domestic waste. Why the low recovery rate of waste paper do? Our legal norms and policy support paper recycling is not enough concrete, not in place. The national paper recycling done quite mature, most of them have a set of interests of all parties thoughtful, strong operational details quantify strict recycling laws system. Authorities for paper companies, mandatory must use a certain amount of waste paper as raw material; recycling business, the provisions of the Government must give some subsidies to ensure their normal operation, to get reasonable value for money; for consumers, law enforcement authorities subject to spot checks, not required for classification of the waste sent to the designated collection point, and fines. By comparison, the recycling of resources not pay enough attention. Imagine, for waste water mixed with sand to earn illegal money was dry, if there is an appropriate policy of subsidies, serious recycling, waste sorting things some people will compete to do good.
People in addressing environmental protection and resource recycling, always likes to emphasize the presence of Chinese and foreign nationals conceptual gap, in fact, the law set the rules, the rules raise habit, habit, naturalizing notion that this is a process. To recycle one specific part of a reasonable standard, including the use of recycled paper, including the "recycling economy" in order to really grow up.
Common failure phenomenon: the entire hydraulic system of the waste paper baler has no pressure or insufficient pressure.
Common causes of failure: the overflow valve fails, and the oil pump is not working properly.
Solution: Check the type of overflow valve used in the waste paper baler equipment. If it is a pilot-operated overflow valve, there are many causes.
1. The overflow valve is stuck or the solenoid fails. If the overflow valve is stuck, clean the overflow valve and reinstall it. If it is electromagnetic failure, you need to check whether the circuit is open, and check whether the coil of the overflow valve is burned. If there is a problem with the circuit, repair the circuit; if the coil burns out, the coil needs to be replaced.
2. If it is the internal wear of the overflow valve, the overflow valve needs to be replaced at this time.
Waste paper baler is an environmental protection equipment that uses hydraulic principles to compress waste paper and waste cardboard into blocks, which is beneficial to waste paper storage, transportation and utilization. https://www.nickbaler.net
The oil pump of the horizontal waste paper baler generally has a plunger pump and a vane pump. The reasons for the loud noise of the oil pump system may include: loosening of the fastening screws of the oil pump; wear of the power bearing or stator of the oil pump; serious damage to the oil pump; inside the oil tank Air bubbles, poor oil intake of the hydraulic pump and other reasons will cause this problem. At this time, we should analyze the specific situation and solve the problem of excessive noise in the hydraulic waste paper baler oil pump!
The possible causes of the failure of the oil pump overheating problem are that the oil pipe is blocked, causing the pressure of the hydraulic oil to increase; the power of the oil pump is too large and overloaded; the hydraulic oil is used unreasonably and the viscosity is too high.
The quality of the hydraulic oil of the hydraulic waste paper Baler has a great influence on the hydraulic pump. The replacement cycle of the plunger pump is generally one year. If the plunger pump is noisy, it is recommended to consider replacing the plunger pump plunger.
The waste paper baler is used to extrude waste paper and similar products under normal conditions to greatly reduce the volume, so as to reduce the transportation volume, save the freight, and increase the benefits for the enterprise. https://www.nickbaler.net
The method of refueling the newly purchased waste paper baler equipment before starting, and the oil leakage problem of the newly purchased horizontal waste paper baler equipment has been plagued by the majority of user groups, so how to solve the problem of the waste paper baler oil Well, let's take a look at the waste paper baler equipment with Nick Machinery. What should I pay attention to when using the refueling method?
1. The oil leakage of the waste paper baler is relatively severe. If the oil pump pressure is adjusted too high, the wear of the movable parts will increase the sealing gap, the sealing device will be damaged, the viscosity of the oil used in the waste paper baler will be too low, etc., which will increase the leakage. After clarifying the reason, adopt the corresponding steps to eliminate it.
2. Poor heat dissipation, insufficient heat dissipation area of ??the fuel tank, too little oil storage in the fuel tank, resulting in too fast oil circulation, poor cooling of the waste paper Baler cooler, such as failure of cooling water supply or failure of electric fans, high ambient temperature, etc. All are the reasons for poor heat dissipation.
3. The system does not have an unloading circuit or the unloading circuit does not perform well. When the waste paper baler system does not need to pressurize the oil, the oil is still overflowing to the fuel tank under the working pressure set by the overflow valve or at the unloading pressure Return to the fuel tank downstream in a higher environment.
4. Misuse of oil with too high viscosity, the waste paper baler will cause excessive hydraulic loss.
