Zoomlion 1020500652 Oil pressure sensor

Product representation

Detailed product information

Function: It is mainly used to control the pressure, temperature, level and other oil parameters in the bulldozer engine. If the oil pressure is too low, the temperature is too high or the fluid level is insufficient, the sensor sends a signal to a control lamp or control system on the dashboard to remind the operator about the need to take timely measures to ensure normal engine operation and prevent damage due to poor lubrication, excessive temperature and other problems.

How does this work

Oil pressure sensor: usually uses piezoresis, tensodic and other principles. For example, in a piezorous sensor, due to the property of the resistance depending on the pressure, with an increase in oil pressure, the resistance inside the sensor decreases, and the electrical signal is respectively increased, and the change in the pressure in the oil circuit is reflected in the change in the output signal.

Oil temperature sensor: usually uses the characteristics of the termistor, the resistance value of which changes depending on the temperature, and determines the temperature of the oil by measuring the resistance value.

Oil level sensor: usually uses a capacitive type, float type and other principles. Capacitive sensors measure the fluid level, detecting a change in the container caused by a change in the level of the oil; Frill sensors use floats to control components such as potentiometers as the fluid level increases and decreases, thereby giving an electric signal corresponding to the fluid level.

The structural composition: usually consists of a shell, a sensory probe, signal processing schemes, connecting wires or connectors, etc. The outer shell is used to protect internal components so that they can work normally in the harsh conditions of the bulldozer; The zond sensor is in direct contact with the engine oil and is responsible for measuring physical quantities, such as oil pressure, temperature or fluid level; The signal processing diagram converts the physical signal detected by the zond sensor into the electrical signal and performs enhancement, filtering and other processing for transmission to the bulldozer control system or to the dashboard.

Stages of installation

Preparation before installation: Prepare the appropriate tools, such as wrenches, screwdrivers, etc.; Buy a oil sensor corresponding to the bulldozer model; Prepare sealants, gaskets and other accessories. At the same time, make sure that the bulldozer is in a safe state, turn off the engine, remove the key and wait until the engine cools down.

Determine the installation location: usually the oil pressure sensor and temperature sensor are installed on the oil channel, and the oil level sensor on the oil pan. The exact location can be determined in the operating manual of the bulldozer.

Disassemble the old sensor: if you replace the sensor, first disconnect the old sensor, then unscrew the sensor with a wrench or screwdriver, observing caution so as not to damage the sensor and the components surrounding it during disassembly.

Clean the installation site: clean the installation site of oil, pollution, etc. And make sure that the installation surface is even and clean to provide a reliable and sealed installation of the sensor.

Install a new sensor: apply the required amount of sealant to the threaded part of the new sensor, correctly install it in the proposed position and tighten the screws or nuts with the help of tools, but do not tighten too much so as not to damage the sensor. Then connect the sensor plug.

Check the installation condition: after installation, check if the sensor is reliably installed, whether the plug is connected correctly, whether there are weakening or leaks.

Common errors

Inadvertent readings of the sensor: this can be caused by the weakening of the connecting wires, poor contact, aging of the sensor or a malfunction of the internal circuit. The solution is to check and tighten the connecting wires. If it is established that the problem is in the sensor, it is necessary to replace a worn or damaged sensor.

Often, an indicator of low oil pressure lights up. The reasons can be an insufficient amount of oil, a malfunction of the oil pump, a sensor malfunction, etc. It is necessary to check the oil level in the engine and, if necessary, add or replace the oil; check the condition of the oil pump and replace it in a timely manner in the event of any problems; Check the sensor and replace it if it is faulty.

Abnormal temperature readings: perhaps there was a failure in the cooling system, which led to an abnormal temperature of the oil, or the temperature sensor itself is worn or damaged. You can check the cooling system for the availability of problems such as a coolant leak or a radiator malfunction, and, if necessary, repair or replace them; At the same time, check the temperature sensor and replace it if it is damaged.

An inaccurate display of the fluid level or an abnormal alarm: the lower seal of the fluid level sensor may fail, which will lead to oil leakage, or the sensor probe can be covered with sludge or impurities, or the sensor itself may be faulty. For problems with sealing, check if the screws are tightened, replace the seals if necessary; If the sensor is contaminated, clean it; If the sensor is damaged, replace it.

After -sales service

Warranty service: As a rule, a certain warranty period, usually 1 year or longer, depending on the brand and the manufacturer, apply to oil level sensors. During the warranty period, if the sensor fails due to quality problems, the manufacturer or dealer must provide the user with free repair or replacement services.

Technical support: manufacturers or distributors must provide professional technical support to answer users' questions about installing, using sensors, etc. Technical consulting services can be provided by phone, e-mail, online support for customer support, etc. .

Repair services: After the expiration of the warranty period, the manufacturer or dealer must still provide repair services and may charge a certain repair fee depending on the seriousness of the malfunction. For some sensors that are not subject to repair, users should provide replacement services in a timely manner, and also make sure that the replaced sensors are compatible with the starting equipment.

Supply of accessories: provide long -term and stable deliveries of accessories for sensors so that if it is necessary to repair or replace users, users can get the necessary accessories in a timely manner and reduce equipment downtime.

Processing of customer reviews: creating a full -fledged feedback mechanism with customers for prompt collection of opinions and users' offers about products and services, as well as to eliminate and optimize existing problems in order to improve the quality of products and the level of service.

The stages of installing oil sensors for different types of bulldozers may differ in the installation site, removal method, connection form, etc. The following:

Determination of the installation site

The Komatsu D65 series: The oil pressure sensor is usually located on the side of the engine next to the oil filter, and the oil temperature sensor can be on oil pallet or cylinder block next to the oil circulation channel. Before installation, it is necessary to find the appropriate position on the side of the engine and the corresponding points on the oil pallet and cylinder block.

SHANTUI SD16 series: Oil level sensor is usually located on the side of the oil pallet, and the pressure sensor is next to the main oil channel of the cylinder block. During the installation, these provisions should be precisely determined taking into account the design of the oil pallet and cylinder block, and you may need to contact detailed drawings or marking of equipment.

Dismantling method

Caterpillar D7R series: Some sensors can have many connections or be blocked by other components. For example, the oil pressure sensor can be closely connected to the engine oil pipeline, wire harnesses, etc. When disassembling it, carefully remove the surrounding fasteners, loosen the buckles, separate the corresponding oil tubes and wires, and then unscrew the sensor.

XCMG TY220 series: When removing the oil sensor, it may be necessary to remove some protective lids or overlays to open the sensor installation locations, and then use special tools to unscrew the sensor. Some sensors can be fixed using special threaded connections or latches, which requires appropriate special tools to remove.

Type of connection

Volvo L120 Series: A rapidly detachable connector can use the oil sensor cable. When installing, just combine the plug of a new sensor with an appropriate nest and click on it. You will hear a click indicating the reliability of the connection.

Series Liugong CLG6360: Some oil sensors can use bolts to connect wires. During the installation, you need to use the tools to tighten the bolts to make sure that the wires are securely connected to prevent a weakening that can cause problems with signal transmission.

Requirements for sealing

John Deere 450K Series: When installing an oil sensor, it may be necessary to apply a special sealant or use a special sealing gasket on the threaded part of the sensor to ensure good sealing and prevent oil leakage.

Zoomlion ZE230E Series: Installation of its sensors may require an extremely high cleanliness of the sealing surface. The sealing surface must be thoroughly cleaned of oil, contaminants, etc., prior to installation, and new seals may need to be replaced to ensure a sealing effect.
