Pre-operational preparation

1, the sensor is installed correctly:

After the sensor is installed on the pipeline, it must be inspected carefully before it is put into operation. Welding is required to be firm, the direction is correct, strict leakage does not occur, and the depth of insertion is appropriate.

2, instrument colleges and universities:

There are differential pressure transmitters and intelligent flow totalizers (there may also be pressure transmitters and temperature transmitters) for sensors. All must be tested and universities must be put into use. The measuring range of the instrument must meet the requirements of the sensor and the measured medium. For example, the measured maximum air flow Qmax = 5000m 3 / h is calculated to calculate the maximum differential pressure generated by the sensor.

ΔPmax = 0.6kpa, the measurement range of the differential pressure transmitter should be 0-0.6KPa in the university, corresponding to the output 4-20MA current signal. For requirements, etc., configure the input integrator in advance so that the integrator can calculate and display the flow correctly.

3, the instrument wiring is correct:

Sensors and differential pressure transmitters, flow totalizers, etc. constitute the measurement system, the power supply line of the instrument, the signal output and input lines between the instruments, and the control and alarm wires, etc., in the wiring board of each instrument (also called the terminal There are clear marks on the board. It must be confirmed and selected. The wiring of the meter before it is put into operation must be checked repeatedly. In order to prepare for operation, in addition to carefully reading the "Willieba Flowmeter User's Manual", it is also necessary to read the "Differential Pressure Transmitter Instruction Manual" and "Intelligent Flow Totalizer User's Manual" and other information, and follow the instructions. Guides work.

Flow meter operation

1. The measurement system is closed: the preparation for commissioning has been completed, the measured medium is full of process piping flow, and the sensor measuring system is temporarily closed. At this time, the balance valve of the three-valve bank should be used, the high pressure valve P1 and the low pressure valve P2. Is off. The supporting instrument is in power supply and is warmed up for about 15 minutes.

The measuring system is switched on: After the instrument is warmed up, the measuring system is switched on. Open the P1 and P2 valves on the three-valve manifold and the balance valve is still open. At this time, the differential pressure transmitter has been charged with the measured medium (gas or liquid), and the discharge valve on the transmitter is turned on, and the dirty liquid gas is rapidly discharged and then closed. Then close the balance valve on the three valve group and the transmitter will enter the differential pressure measurement state. Output differential pressure

ΔP corresponds to the signal current 1 Δ P from the signal current value (MA) can calculate the differential pressure Δ P value (KPa). Flow integrator also enters the working state, showing the measured medium flow.

If the above work is successful and the flow meter is working properly, the commissioning work will be completed and delivered for production use.

Brake System Accessories

Wheel loader Brake System Accessories include: Air Booster Pump, Air Brake Valve , Loader Brake Clamp, loader brake pads and so on.
Air Booster Pump uses air pressure as power to push the piston in the air chamber. Through the transfer of the push rod, the cylinder piston moves, thus increasing the pressure of the brake fluid, and then transferring it to the brake caliper to play the braking effect.
Air Brake Booster have different specifications and models, which are widely used in Liugong, XCMG, XGMA, Lonking, Yutong, SDLG, SEM, JGM, ENSIGN and so on.
At present, the brake system of wheel loader generally adopts gas cap oil comprehensive brake.Air-cap oil comprehensive brake is mainly composed of air compressor, oil-water separator combined valve, air storage tank, foot brake, air afterburner, brake pipeline and other components. The air afterburner is a very important braking element, which can directly convert the gas pressure energy generated by the compressed air to the liquid pressure energy generated by the pressurized gas piston, so as to push the clamp disc brake on the dry drive axle for braking. If the air afterburner fails, the braking performance of the loader will be reduced or lost, which will seriously threaten the safety of human life. Therefore, it is very necessary to understand the structure and principle of air afterburner pump for the selection, maintenance and repair of air afterburner pump of loader.
