Product Description

Details:
Vacuum solenoid valve Overview:
Dc-jq type electromagnetic vacuum with charging valve is a special valve installed on the mechanical vacuum pump, and connected with the pump on the same power supply, pump opening and stopping directly control the opening and closing of the valve. When the pump stops working or the power supply is suddenly interrupted, the valve can automatically close the vacuum system, and the atmosphere is filled into the pump chamber through the valve's inflation port, so as to avoid the pump oil countercurrent pollution of the vacuum system.

Solenoid Valve Navigation - The basics of solenoid valves
Solenoid valve is used to control the basic components of automation fluid, belongs to the actuator; Is not limited to hydraulic, pneumatic. The solenoid valve is used to control the direction of hydraulic flow. The mechanical devices in the factory are generally controlled by hydraulic steel, so the solenoid valve will be used. Solenoid valve has a closed chamber, in different positions open through the hole, each hole leads to a different tubing, the middle of the cavity is the valve, both sides are two electromagnets, which side of the magnet coil energized valve body will be attracted to which side, by controlling the movement of the valve body to block or leak out of different oil discharge holes, and the oil inlet hole is often open, hydraulic oil will enter different drainage tubing, And then through the pressure of oil to promote the oil of the piston, the piston and drive the piston rod, the piston rod drives the mechanical device. In this way, by controlling the current of the electromagnet, the mechanical movement is controlled.
Use and maintenance :
1, it is recommended that the use of the unit assign a person responsible for the use and maintenance of
2, 1-2 times a year of regular maintenance is the solenoid valve reliable work and longevity of the best way. The following 4 situations inside the solenoid valve are the reasons that hinder the normal work of the solenoid valve and shorten its life. (
1) Changes in the medium in use (
2) Rust in the nozzle (3) oil oxidation of the
air compressor, resulting in carbon tar and other debris, Mixed into the pipeline 2.4 There are impurities such as dust particles and dirt in the pipeline
3, after the installation of the solenoid valve or a long time after it is put into operation again, it must pass the medium test action several times before normal work can be formally used
4, before maintenance, you must cut off the power, remove the medium pressure
.5, coil components should not be opened
6, open the solenoid valve for cleaning, you can use kerosene, trichloroethylene and other solutions. However, it should be noted that the rubber parts may dissolve, so it must be replaced.7
, disassembling and cleaning, the parts should be installed in order to restore the original state.
