Electromagnetic pulse valve bag dust collector spray pneumatic valve right Angle valve bag type submerged valve diaphragm 1-4 inches

Dmf-z series right angle electromagnetic pulse valve is a special electromagnetic valve specially designed for the matching use of bag type dust remover. It is the compressed air switch of the dust cleaning injection system of the pulse bag type dust remover. Controlled by the output signal of the pulse injection controller, it injects the dust on the filter bags row by row (room), so that the resistance of the dust remover is kept within the set range, so as to ensure the processing capacity and dust collection efficiency of dust removal, Achieve the purpose of shaking the cloth bag to remove dust.

Installation precautions are as follows:

1. During installation, it should be noted that the arrow on the valve body should be consistent with the flow direction of the medium. Do not install it where there is direct dripping or splashing. The solenoid valve should be installed vertically upwards.

2. The solenoid valve shall ensure normal operation within the fluctuation range of 15% - 10% of the rated voltage.

3. After the solenoid valve is installed, there shall be no reverse differential pressure in the pipeline. And it needs to be powered on several times to make it suitable for temperature before it can be officially put into use.

4. The pipeline shall be thoroughly cleaned before the installation of solenoid valve. The medium should be free of impurities. A filter is installed in front of the valve.

5. When the solenoid valve fails or is cleaned, a bypass device shall be installed to ensure the continuous operation of the system.

Troubleshooting:

1、 The solenoid valve does not work after being energized

Check whether the power wiring is poor → reconnect the wiring and connector

Check whether the power supply voltage is within the ± working range - → adjust to the normal position range

Whether the coil is desoldered → rewelded

Coil short circuit → replace coil

Whether the working differential pressure is inappropriate → adjust the differential pressure → or replace the matching solenoid valve

The fluid temperature is too high → replace the matching solenoid valve

The main valve core and moving iron core of the solenoid valve are blocked by impurities → clean them. If the seal is damaged, replace the seal and install the filter

The liquid viscosity is too high, the frequency is too high and the service life has reached → replace the product

2、 Solenoid valve cannot be closed

The seal of the main valve core or iron moving core is damaged → replace the seal

Whether the fluid temperature and viscosity are too high → replace the corresponding solenoid valve

Impurities enter the valve core or moving iron core of the solenoid valve → clean it

Spring life has expired or deformed → replace

Orifice balance hole blocked → timely cleaning

Working frequency is too high or service life has reached → change products or update products

3、 Other situations

Internal leakage → check whether the seal is damaged and whether the spring is poorly assembled

Leakage → loose connection or broken seal → tighten screws or replace seals

There is noise during power on → the fasteners on the head are loose and tightened. The voltage fluctuation is not within the allowable range. Adjust the voltage. Clean or replace the iron core in time if there are impurities or unevenness on the absorption surface.
