Sany B229900002662 Electromagnetic stop valve

Product representation

1. The structure of the product

Electromagnetic node: consists of an electromagnetic coil, an iron core and anchor. The electromagnetic coil is tightly wound with a high -quality enameled wire, which can quickly generate a stable and strong magnetic field when turned on. The iron core is made of special material with high magnetic permeability, which allows you to effectively enhance the magnetic field strength and increase the speed of the electromagnetic valve. Under the influence of magnetic field strength, the anchor can quickly attract and release, and also accurately control the opening and closing of an oil or gas circuit.

The valve core knot: the valve core is a key component for controlling the liquid channel and is usually made of high -strength, wear -resistant metal materials such as stainless steel. Its surface is subjected to accurate machining, which provides smooth movement inside the valve body and reduces friction resistance. The sealing ability between the valve core and the valve saddle is good. The use of special sealing materials and structural design can effectively prevent fluid leakage and ensure the normal operation of the electromagnetic valve.

Corps: made of high-strength, heat-resistant and corrosion-resistant structural plastic or metal. The outer shell not only protects the internal electromagnetic components and components of the valve core from erosion and mechanical damage under the influence of the external environment, but also has good insulating properties that ensure safety during use. The case is usually equipped with mounting holes and marking to facilitate installation and identification.

2. Operational characteristics

Quick response: Thanks to the optimized design, after receiving the control signal, the valve core can be moved in a very short time (usually within a few milliseconds), quickly overlapping or connecting the oil circuit, quickly turning off the engine and increasing the efficiency of operation and equipment safety.

High reliability: after strict quality control and durability tests, the device can work steadily in difficult working conditions. Even in harsh conditions, such as high temperature, high humidity and strong electromagnetic interference, it can maintain good performance by guaranteeing the reliable operation of the Sany excavator flame and reducing equipment downtime, caused by the electromagnetic valve failure.

Low energy consumption: an electromagnetic coil uses an advanced energy -saving technology that reduces the energy consumption and load on the excavator power system, while ensuring normal operation, thereby increasing the efficiency of energy use.

High adaptability: it is specially designed for various types of Sany excavators, such as SY75, SY135, SY215, SY305, etc. It can perfectly correspond to the electrical system and the excavator engine. It is easy to install and can be commissioned without difficult debugging.

3. The installation method

Preparation: Make sure that the excavator is in a safe shutdown state, remove the key and disconnect the negative battery cable to prevent lesions with electric shock or short circuit during installation. Prepare the necessary tools, such as wrenches, screwdrivers, pliers, etc., as well as a new electromagnetic flame disruption valve and appropriate mounting supplies, such as gaskets, bolts, etc. At the same time, check whether the model of the new electromagnetic valve equipment corresponds to the equipment And whether there are any damage to the appearance.

Remove the old electromagnetic valve: Find the installation location of the old electromagnetic flame disruption valve, which is usually located in the fuel line or the intake part of the engine control. You can contact the manual for the maintenance of the excavator to determine a specific place. Using a screwdriver, unscrew the screws holding the solenoid, and carefully remove the old solenoid. Mark the location of the wires and oil tubes connecting the electromagnetic valve for subsequent installation. If the wires and oil tubes are tightly connected, you can carefully pull them out with pliers, but be careful not to damage the wires or tubes.

Install a new electromagnetic valve: combine a new electromagnetic flame disruption valve with a mounting hole in accordance with the marked position and fix it with screws, but do not tighten them. Then connect the wires and oil tubes in the order specified earlier, making sure that the connections are reliable, the plugs are tightly tightened, and there are no leaks in the oil tubes. Finally, tighten the fasteners with a screwdriver to make sure that the electromagnetic valve is securely fixed, does not stagger and does not weaken.

Checking and eliminating problems: after installation, check whether the electromagnetic valve is reliably installed, whether the lines and pipelines are correctly connected, whether there are weakening, short circuits or leaks. Connect the negative battery cable, start the excavator and check the operation of the shutdown solenoid. When the circuit breaker is triggered, the electromagnetic valve should work quickly, gradually stopping the engine. If it is found that the electromagnetic valve works abnormally, for example, does not react, it makes an abnormal noise or the engine does not turn off smoothly, etc., the engine should immediately stop and check, and then repeat the check after eliminating the malfunction.

4. Precautions when using

Correctly operate the flame disruption switch: when operating the excavator flame switch, do it smoothly and avoid it fast and frequent turning on and off so as not to damage the electromagnetic flame disruption valve and not reduce its service life. Every time you turn off the engine, make sure that it stopped completely before performing other operations.

Avoid overload: do not use the electromagnetic valve if the voltage and current exceed nominal values, otherwise the electromagnet coil and the valve core will fail faster. Regularly check the electrical system of the excavator to make sure that voltage and current stability, as well as avoid overloading the electromagnetic valve due to electrical malfunctions.

Keep clean and dry: regularly clean the outer shell of the electromagnetic flame breakdown to prevent dust, butter and moisture inward and violation of its normal operation. Especially in difficult working conditions, for example, at dusty or wet construction sites, cleaning and protection should be strengthened. If water or moisture is detected on the surface of the electromagnetic valve, it should be wiped dry and dried in a timely manner to provide good insulation characteristics.

Regular inspection and maintenance: regularly check the operating condition of the electromagnetic valve, including whether the core of the valve is flexible, whether the coil of the electromagnet is overheated, whether the connecting line is weakened, etc. If it is detected that the valve core is stuck, the solenoid coil is damaged or the connecting line is torn, the solenoid valve should be replaced or Timely repair the line to ensure the normal operation of the flame disruption system.

Prevent electromagnetic interference: try to avoid installing the sources of strong electromagnetic interference near the electromagnetic flame disruption valve, such as large engines, welding machines, etc. If this cannot be avoided, you should take on shielding measures, for example, use a metal protective casing to close the electromagnetic valve to reduce the effect of electromagnetic interference on the electromagnetic valve and Prevent its malfunction.
