Precautions And Key Points For Filter Installation

Generally speaking, the prefilter can filter out the large particles of sediment in water, clean domestic water, near Oh, conducive to people’s life and health. At the same time, the prefilter can also prevent and protect the water dispenser, coffee machine and other devices. In addition, the prefilter can also remove rust and other substances from water pipes. In general, the prefilter is the first cleaning device for household water.

Generally speaking, the pre filtration device can be used for domestic water, but also can be used for the upstream of the system, plays a key role in protection. For example, it is used for drinking machine, dishwasher, coffee machine, washing machine, central air conditioner, etc. At the same time, it can also be used in sewage treatment devices, and can also be used for the treatment of rust in pipes. At the same time, the prefilter can also be used to extend the service life of pipes, such as faucets, toilets, or other bathing devices.

The prefilter is usually installed in the front of the pipe. That’s why it’s called a prefilter. It can also be installed behind the meter of the water pipe. His main role here is to prevent the impact of a large amount of precipitation on the human body, and also to extend the service life of the pipe and other devices behind the prefilter, that is, to protect the faucet or other electrical appliances. The prefilter is a relatively reliable impurity filtering device. The prefilter mainly relies on the valve to control its switch, which is mainly used as the first cleaning device of the drainage system.

1) The installation position of the filter in the hydraulic system mainly depends on its purpose. In order to filter the dirt from the hydraulic oil source and protect the hydraulic pump, a coarse filter should be installed in the oil suction pipeline. In order to protect the key hydraulic components, a fine filter should be installed in front of it, and the rest should be installed in the low-pressure circuit pipeline.

2) Pay attention to the liquid flow direction indicated on the filter shell. Do not install it reversely. Otherwise, the filter element will be destroyed and the system will be polluted.

3) When the net filter is installed on the oil suction pipe of the hydraulic pump, the bottom of the net filter should not be too close to the suction pipe of the hydraulic pump, and the reasonable distance is 2 / 3 of the height of the filter net, otherwise, the oil suction will not be smooth. The filter must be fully immersed below the oil level, so that the oil can enter the oil pipe from all directions, and the filter screen can be fully utilized.

4) When cleaning metal braided square mesh filter element, brush can be used in gasoline. When cleaning high-precision filter element, super clean cleaning solution or cleaning agent is needed. The special mesh woven with metal wire and stainless steel fiber sintered felt can be cleaned by ultrasonic or liquid flow back flushing. When cleaning the filter element, the filter element port should be blocked to prevent dirt from entering the filter element cavity.

5) When the filter differential pressure indicator shows a red signal, clean or replace the filter element in time.
