How to use a solvent filter, what details need to be paid attention to?

There are many things to look out for, depending on what you are using for it, and what is the solution you are storing?

For example, if you use an acidic sediment, wash it with alkaline. Wait a minute.

Note: 1. Before using the stainless steel filter, you must check whether the accessories and sealing ring are complete and whether there is any damage, and then install it as required.

2. The new filter must be cleaned with detergent (please do not use acid cleaning) After washing, the filter should be sterilized, disinfected and cleaned with high temperature steam to avoid pollution.

3. Do not reverse the inlet and outlet of the filter during installation, the mouth on the side of the bottom plate of the pipeline filter is the liquid inlet, and the pipe connected to the filter element socket is the clean liquid outlet.

4. The new filter element is sealed in a plastic bag in a clean production plant by the manufacturer, and the plastic packaging should not be torn if it is not used, and the filter element with higher requirements should be sterilized and sterilized by high temperature steam after installation.

5. When the filter element is inserted into the port, the filter element must be vertical, and the pressure plate buckles the tip fin after the insertion port, and the screw can be tightened and not moved. After the filter element inlet of the 226 interface, it should be rotated 90 degrees to clamp, which is the key in the installation, if you are not careful, it will not reach the seal, easy to leak, and it will not meet your use requirements.

6. When the filtered liquid enters, the air release switch on the filter should be turned on to fill the cylinder with the liquid, otherwise the filtration effect is not good.

7. The pressure gauge of the cylinder is a liquid pressure display gauge, if it is a secondary filtration, it is normal for the pressure gauge index of the first filter to be slightly less, the longer the use time, their pressure will increase and the flow rate will decrease, which indicates that most of the filter element voids have been blocked, and the filter element should be flushed or replaced with a new one.

How to use the filter: Put the filter into the aquarium, fix it on a certain side with a suction cup, and turn on the switch to use it. Notes:

1. The filter can only be used according to the rated voltage and frequency indicated on the nameplate. 2. The filter should be maintained every once in a while. Before cleaning and maintenance, disconnect the power supply of the filter.

3. Make sure the wire plug is dry. 4. Do not unplug the power cord with wet hands. 5. The filter is only used in indoor aquariums.

6. The filter cannot be used when it is damaged. 7. Make sure that the filter works in the correct water level, and the filter cannot be used in the absence of water. 8. The filter cannot be dismantled or repaired without permission to avoid danger or damage to the body, and the filter maintenance should be carried out by professionals.

Test Answers: [Answer] (1) AC E D A (2) O2 (or CO2) 2H2O22H2O+O2 (or CaCO3 2HCL CaCl2 CO2 H2O) B Test Question Analysis: [Analysis] (1) According to the use of commonly used instruments in chemical experiments, it can be known:

What is needed for filtration is a funnel; Instruments that can be directly heated include test tubes and evaporation dishes; Gas collector cylinders that can be used to collect or store small amounts of gas; The beaker that can be used as a reaction vessel for the preparation of solutions and larger quantities of reagents is the beaker; (2) Device A is a solid-liquid gas production device, and device D is an upward air exhaust method, which collects gas with a greater density than air, so carbon dioxide or oxygen can be selected (using hydrogen peroxide and manganese dioxide to produce oxygen); The device is another device for collecting gas by drain method, the use method of forward and backward is different, after the E device is filled with water, the gas enters from the B end, and with the increase of gas, the internal pressure increases, forcing the liquid to go out from A (or the E device is filled with water and then reversed, and the gas enters from the A end).

Nowadays, most of the fish are raised in bare tanks, and the advantage of bare tanks is that they are easy to clean, and dirt is not easy to accumulate at the bottom of the tank. However, due to the lack of nitrifying bacteria in the tank, the self-cleaning ability is very poor, and if the fish are densely fed and fed, the water will be turbid in many cases. Also because the BB of the fish can not be decomposed and transformed by nitrifying bacteria in time, the ammonia nitrogen substances in the tank exceed the standard, which is easy to lead to the growth of algae, and the long-green moss makes the water body green, and can only absorb these harmful substances through algae and moss, so as to achieve a new balance, but this also affects the ornamental nature of the aquarium.

Yongqing filtration system, by cultivating a large number of nitrifying bacteria in the tank, it is possible to grow moss in the fish tank.

The innovative Yongqing filtration system has a special function to automatically clean the waste from the bottom of the tank, completely eliminating the need for manual cleaning with straws or sand washers. The Yongqing filtration system is composed of a flow pump, a water pump, a biochemical mesh plate, a water pipe, and a filtration tank. The system can lay the bottom sand on the biochemical net, so that the biochemical mesh plate and the bottom sand provide a large area of nitrifying bacteria epiphytic, and decompose and transform harmful substances such as fish excrement in a timely manner through the physiological function of nitrifying bacteria.

The flow-making pump creates a directional flow of water under the mesh plate and directs the precipitated waste to the pumping outlet, where the filtered water flows back into the tank.

The Yongqing filtration system is a combination of upper filtration and bottom filtration in form, and in essence, it is the optimal and perfect combination of physical filtration and biochemical filtration.

The Yongqing filtration system can establish a stable ecological balance in the fish tank. It is perfectly suitable for feeding high-density or large freshwater and marine fish. The system does not need to manually clean the waste of the bottom sand, as long as the filter is cleaned regularly and the water is partially changed, the water quality can be kept stable and clear, and moss will never grow.

Effectively reduce the daily maintenance and cleaning work of fish farming, so that you can enjoy the fun of fish farming more easily, and also create a favorable environment for the healthy growth of fish. For details, please filter forever.

What filter? Plot filter, or Internet filter or air filter or oil filter or water filter? Please be clear.

First of all, check whether the material is damaged, if the Pei Qiguo is not damaged, plug it directly and pay attention to the water level in the middle of the water, if you have not started to filter, manually drain, because there is no water in the new equipment, you need to manually drain and add water.

Features:

Solvent filter: classic design, easy to use.

Rubber plug filter: Compared with the solvent filter, this product is connected by rubber stopper, which is easy to plug and unplug, and the upper membrane replacement part can also be used with a multi-filter bracket, which is more diverse.

Glass membrane change filter: used in conjunction with multi-filter holder, economical and practical.

Stainless steel membrane change filter: Used in conjunction with a multi-filter holder, this product is durable and wear-free compared to glass membrane change filters.
