How to maintain y strainer
Y strainer is a kind of good filtering equipment in pipeline system. It has good filtering effect for medium and is easy to disassemble and clean. Many users are willing to purchase Y strainer for their pipeline system.
After daily use, in addition to timely replacement of Y strainer, it is also necessary to carry out regular maintenance and maintenance, so as to extend its service life under normal use, and the use effect has been good.
How to clean Y strainer
On the outside, the Y strainer should be regularly dusted and oiled. Dust removal refers to the accumulation of a layer of stains on the surface of Y strainer after a long time of use. These stains sometimes erode the surface, so it is necessary to clean them regularly. Oil painting refers to the application of anti rust oil to prevent Y strainer from rusting in the open air and then damage.
For the interior, not only the strainer screen should be replaced regularly, but also the strainer screen should be disassembled and flushed regularly. This is mainly due to the fact that there are some solid impurities in the media to be filtered, and these impurities will accumulate in the pipe wall when the Y strainer flows through, and the accumulation for a long time is easy to cause damage to the inner wall of the Y strainer.
There are several steps to pay attention to when using the Y strainer. First, when installing, the water flow direction of the system should be consistent with the arrow direction on the valve, horizontal or vertical is OK. Second, in the Y strainer after the installation of the strainer screen to see whether there will be water leakage, if the phenomenon of water leakage, the seal gasket may be damaged, replacement can be. Third, it is necessary to check whether there are too many impurities in the Y strainer on time. This method can be used to install pressure gauges at both ends of the strainer. When the pressure readings at both ends differ greatly, it indicates that there are many impurities in the strainer screen, which can be cleaned. Fourth, the strainer should be installed together with the stop valve. The stop valve should be installed in the upstream, downstream and downstream of the strainer, so that it is easy to operate during maintenance.
When repairing the Y strainer, it is necessary to clean the strainer frequently, which is easy to breed bacteria and pollute the liquid in the pipeline. In this note, in order to protect the equipment to work normally for a long time and a long time, it is necessary to protect the accessories on the equipment pipeline from abrasion and blockage during daily use and maintenance.
Y strainer is Y-shaped, one end is to make water flow through, and the other end is deposited waste and impurities. Generally, it is installed in pressure reducing valve, pressure relief valve, constant water level valve or other equipment Therefore, the effect of removing impurities in the water by the stainless steel inlet of the filter body is normal. After the differential pressure switch monitors the change of the pressure difference at the inlet and outlet, when the pressure difference reaches the set value, the electric controller sends signals to the hydraulic control valve and the driving motor, causing the following actions: the motor drives the brush to rotate, cleans the filter element, and opens the control valve together for sewage discharge. The whole cleaning process only needs tens of seconds. When the cleaning is finished, the control valve is closed and the motor stops changing, When the system reaches its initial state, it begins to enter into the next filtration process. After the equipment is installed, the technical personnel will carry out debugging, set the filtering time and cleaning change time, the water to be treated enters the body through the water inlet, and the filter starts to work normally. When the preset cleaning time is reached, the electric controller sends signals to the hydraulic control valve and the driving motor, causing the following actions: the motor drives the brush to rotate, cleans the filter element, and opens the control valve together The whole cleaning process only needs to continue for tens of seconds. When the cleaning is finished, the control valve is closed, the motor stops changing, the system reaches its initial state and begins to enter the next filtration process.
