What is the fault of the sprayer E17? The sprayer shows fault E one

Analysis and treatment of common fault causes of Guiyang spraying machine.

1. In the process of work, the sudden automatic shutdown may be caused by:

1. If there is a sudden power failure at the construction site, if the power supply will not be restored in a short time, the power supply must be cut off, the conveying hose, pump core and all accessories must be removed, and cleaned. When disassembling the conveyor pipe, the disassembly place must be covered with a packaging bag or other items to prevent the sudden release of pressure in the pipe at the moment of disassembly, and the danger of shooting out the mortar.

2. If the motor is overloaded, check whether the fuse is blown out.

Second, the slurry is too dry or the downtime is too long and not cleaned, which may lead to blockage failure.

Blockage is also one of the causes of overload, and in this case, it is necessary to unblock the blockage. Turn off the power first, do not disassemble the spray gun or conveying hose immediately, otherwise the huge pressure in the pipe will be released from the disassembly place, and the explosion of mortar will be dangerous.

1. Turn the power supply to the reverse direction.

2. Press the button to turn on the machine, and turn the machine backwards for about 30 seconds to reduce the pressure in the conveying pipe.

3. Remove the spray gun and clean it. Check if the nozzle is blocked.

4. Turn the power switch to forward rotation and turn it on.

5. If the conveying hose is sent out without material, it means that the pipe is blocked, and the cleaned spray gun can be connected to continue the spraying work.

6. If the conveying hose is sent out without material, it means that the pipe is blocked, and it can be opened and reversed several times. If there is still no material to be sent, the conveying pipe is removed for cleaning and dredging, and the conveying hose is removed, which can only be carried out after opening and reversing.

7. Connect the dredged conveyor pipe, and then adjust the button to the forward rotation and restart the machine.

3. The machine rotates normally, but the pulping is very slow or does not produce pulp, which may be due to:

1. The pump core has been worn out for too long, how to judge whether the pump core is worn? A pressure gauge can be connected between the outlet of the pump core and the delivery hose, and if the pressure gauge shows little or no pressure, the pump core can be judged to be worn. That is, the pump cartridge needs to be replaced.

2. The rotating part of the hopper is evacuated to form a space, because the slurry is too dry or the dry powder flow is poor, which is not suitable for mechanical operation.

Mortar spraying machine manufacturers @ common troubleshooting methods for mortar spraying machines.

Mortar spraying machine in the construction process often appear in a variety of reasons to form mechanical failures, affecting the construction progress, mortar spraying machine common fault solutions, here to share with you, so that users can proficient control mechanical spraying technology.

1. The amount of spraying becomes smaller, and the amount is uneven. In the normal spraying, the flow suddenly becomes smaller and the discharge is uneven, generally there are the following reasons, the distance of the spraying pipeline is too long, which will cause the flow rate to decrease, under normal circumstances, it is controlled within 40 meters, and the friction between the mortar and the pipe wall increases the farther the distance, resulting in a gradual decrease in the flow rate. The movement of the air rod in the spray gun leads to uneven discharge, and the distance between the center of the air rod and the spray gun, and the distance between the front and back before each spraying.

If the air at the discharge port is abnormal, there will also be poor atomization, you can check whether the air compressor is running normally, and the general air pressure is normal, and at the same time check whether the air pipe is leaking and whether the gas rod is blocked.

2. Reasons and treatment methods for pipe blocking: the pipe blocking phenomenon caused by excessive pressure during spraying, the conveying distance is too far during spraying, the height is too high to produce excessive pressure, and the other is the foreign body blockage at the mouth of the spray gun, which increases the pressure in the mortar pipe, so that the water leakage phenomenon occurs at the interface, resulting in the pipe blocking phenomenon, which is generally a precursor, the flow rate is significantly reduced in the spraying process, and the working pressure gradually rises. If there is no timely shutdown and the pipeline is seriously blocked, you can only clean the pipe with water to exclude, and choose the appropriate hose to flush right down and up.

3. The main motor can not be started: the mortar is too long away from the conveying, which increases the resistance of the mortar conveying and exceeds the effective load of the motor, so in the effective spraying distance of the mortar spraying machine, the conveying distance is shortened as much as possible, and the resistance of the centrifugal mixer is increased due to insufficient lubrication.

4. The air compressor cannot be started: the pressure switch is too high, or the switch on the air compressor is not opened, and the air valve switch on the spray gun is not opened. The air needle in the spray gun is blocked, turn on the air pump first every time the machine is turned on, and turn off the air pump after the machine is turned off to prevent the cement slurry from flowing back into the air needle and causing blockage.

Graco Airless Sprayer Failure Phenomenon: Spraying Equipment Weakness Possible Causes: Pressure is set too low, Solution:

Adjust the voltage regulating button to higher Airless sprayer fault phenomenon: the equipment does not start, the electronic pressure gauge does not light up Possible causes: no voltage, the switch is not turned on or damaged, and the fuse is broken Solution:

Check the power supply, turn on or replace the switch, replace the fuse Airless sprayer Fault Phenomenon: The equipment does not start, the electronic pressure gauge is lit Possible causes: The pressure adjustment button is placed in "Stop", and the pressure setting is too low.

Solution: Increase the pressure control button Airless sprayer Fault phenomenon: possible reasons for not drawing paint:

Suction filter protrudes from the paint surface, filter blockage, paint extraction pipe loosens and leaks, paint suction valve shelving Solution: add paint, clean or replace the filter, clean the filter, replace the O-ring if necessary, and press the push rod several times.

Failure phenomenon of airless sprayer: it can draw paint, but the pressure is small, and the possible reasons are: the nozzle is seriously worn, the nozzle is too large, the pressure is set too low, and the filter is blocked.

When the safety valve is in spray, the paint flows out of the return pipe, the seal is bonded or damaged, the valve ball is damaged, and the valve seat is damagedSolution: replace the nozzle, replace, increase the pressure, clean or replace the filter, clean or replace the safety valve, replace, replace, replace.

Airless sprayer failure phenomenon: paint overflowing from the top of the paint tank possible causes: upper seal breakage, plunger damage Solution: Remove the seal and replace it. Remove the plunger and replace it.

Airless sprayer failure phenomenon: Possible causes of increased gun vibration: incorrect model of high-pressure pipe, broken or too large nozzle. The pressure is too high. Solution: Please use the original high-pressure pipe and replace the nozzle. , adjust the pressure to a lower value.

Airless sprayer fault phenomenon: motor operation indicator light continues to red shutdown possible causes: motor overheating Solution: Strengthen equipment ventilation, switch to a smaller nozzle or lower the pressure, and clean the radiator air duct at the rear of the motor.

Airless sprayer failure phenomenon: Poor spray shape possible causes: nozzle is too large or worn, pressure setting is incorrect.

Paint quantity too low, filter clogging solution: paint viscosity is too high, nozzle clogging Replace the nozzle, refer to the nozzle data sheet. , adjust the regulator knob until you get a satisfactory spray shape, wash or replace all filters, and dilute the paint.

Rotate the nozzle 180° towards the paint bucket for a moment, then turn it back.

As an important spraying equipment, high-pressure airless spraying machine needs to master the correct use method in order to improve efficiency and make the spraying more uniform and beautiful. At the same time, in the process of use, it is inevitable that there will be some minor failures, in order to deal with such a situation, it is important to know some maintenance methods. Below, let's follow along to find out.

How to use: 1. The sprayed materials should be shielded, and the spraying equipment used should not collide with the protection facilities.

2. For all kinds of pipelines, the pipe mouth needs to be wrapped before spraying.

3. When spraying the edges of doors and windows, pay attention to covering the doors and windows.

4. Before using the spraying machine, remember to block the place that should be blocked, otherwise the project completed before will be in vain.

Fault Repair: Fault.

1. The automatic paint spraying machine does not spray oil.

Exclusion method: 1. Check whether the oil pump is oiled, whether the air pressure and oil pressure valve are adjusted to a certain pressure, and whether the oil circuit is blocked and cleaned;

2. Whether the switch of the spray gun is high enough, and whether the ejector pin of the spray gun is bounced up when pressed; If the oil is not yet out, clean the inside of the spray gun and the cap, and pay attention to the oil seal of the spray gun can not be immersed in corrosive liquids such as toluene to prevent deformation and damage.

Fault. Second, the automatic painting line is not moving.

Exclusion method: 1. Check whether the inverter is started and whether the parameters are correct;

2. Whether the chain is stuck and broken;

3. Whether the motor is running or not, and whether the overload protection switch is reset.

Fault. 3. The manipulator of the automatic spraying line does not move.

Exclusion method: 1. Check whether the manipulator has an alarm signal, and ask professional maintenance personnel to solve it according to the alarm signal;

2. Press the manipulator again to return to the original point, and observe whether there is a return to the origin and normal state;

3. The manipulator servo motor wire head is loose and re-inserted;

4. When the servo motor fails, please notify the manufacturer for maintenance.

The above is the introduction of the use of the spraying machine and fault maintenance, I hope it can help you in your daily use.

The faults of airless sprayers can be roughly divided into two categories: coating system failures and air system failures. When we encounter a fault, we can check and eliminate it ourselves, which can not only save time and money, today we will take a look at the pneumatic airless sprayer, what to do if there is a failure?

When there is a fault, it should not be blindly disassembled, and the following methods should be analyzed and eliminated.

Fault symptom 1:

The air motor can be reversed normally, but the reciprocating motion is uneven, the amount of spraying is small and weak, and the sprayer cannot stand still after the gun is turned off.

1. The release valve is not closed tightly. Judgment method: There is paint flowing out of the vent pipe.

2. Check whether the suction filter is blocked;

3. The two ends of the suction hose are not well sealed, and the air leaks, and the shipbuilding coating cannot be sucked in. Judgment method: remove the suction tube, and insert the elbow of the suction tube directly into the small barrel of paint or thinner, and the fault phenomenon will be eliminated.

4. The suction valve is not closed tightly, and the steel ball cannot be reset in time due to foreign matter blocking at the valve port, or cavitation at the valve port. Judgment method: open the vent valve, suddenly close the vent valve when the piston rod is down, and the piston rod cannot be stopped immediately.

5. The plunger valve is not closed tightly, the foreign body is blocked, the spring is broken, and the steel ball or valve port is cavitated. Judgment method: open the release valve, suddenly close the release valve when the piston rod is up, and the piston cannot be stopped immediately.

6. The V-ring on the plunger body is worn and leaked. Judgment method: open the release valve, suddenly close the release valve when the piston rod is up, and the piston rod cannot be stopped immediately.

7. You have V-ring wear and leakage on the pump seat. Judgment method: The oil cup and paint of the split pump seat are exposed, and the paint leaks from the observation hole of the integral pump seat.

Generally speaking, there are hard failures and soft failures.

Hard faults have excessive wear of functional parts, resulting in aging of parts and easy blockage of pipelines.

Soft failure, improper operation, parts wear, failure to clean up in time after materials, reaction in the barrel machine Blockage.

Buying a machine to find a strength factory will reduce a certain cost.

Fault: Slow heating up when baking paint.

Possible reasons: 1. The damper is not opened.

Elimination method: 1. Check whether the damper is operating Fault: black smoke is emitted after the burner is ignited.

Possible causes: 1. The timetable setting time is one to 2, the temperature displayed by the thermometer is to the set temperature 3, and the oil pump is stuck.

Exclusion method: 1. Reset the time 2. Reset the temperature 3. Check whether the oil pump shaft is stuck with debris or oil residue.

Fault: The air volume is too small when painting.

Possible causes: 1. The first filter is blocked 2. The damper is open.

Elimination method: 1. Clean each filter 2. Check whether the damper is operating Fault: The main fan does not start.

Possible causes: 1. The fuse blows 2, the thermal relay is out of position 3, and the electrical appliance is short-circuited.

Troubleshooting method: 1. Replace the fuse 2, press the reset button 3, replace the motor Fault: The burner fault indicator light is on 15 minutes after the burner starts.

Possible causes: 1. There is no oil in the oil tank 2, there is an air leak at the tubing joint 3, the filter screen on the oil inlet pipe is too dirty 4, the electric eye is too dirty and the sealing failure failure The sealing rubber ring of each part has an aging and failure period, and the sealing gong buckle may also be self-loosening, which will cause pressure loss, and it needs to be checked and replaced and fastened from time to time. 2. Mechanical movement disorders need to be lubricated and replaced from time to time with aging and worn mechanical parts.

3. Blocking faults should prevent paint agglomeration or deposition from blocking equipment and pipelines, and flush and clean equipment and pipelines in strict accordance with standards when the time limit is exceeded (different coating requirements are different).

Generally, there is e-17, or the more you spray, the more weak it is, and the motor speed is slow, which is caused by the bottom of the current. The motor should be kept at 230 to 200 currents. If the current is not enough, the motor will not rotate, and there will be an e-17 fault.

Hello, e = 05 The sprayer stops working, but there is an excessive current Check if the rotor is locked, if the pump body is blocked, if the return valve is damaged, and if the wire or motor is short-circuited. e = 02 sprayer stop working, but there is too much electric pressure to clean the balance socks to start the blocked filter e = 03 sprayer stop working, but there is electric pressure control good speed device bad or wire connection failure check pressure controller and wire, if necessary, replace e = 04 sprayer stop working, but there is too high voltage check power supply hope my reply can help you, if there are follow-up questions, please ask me, I will reply to your <> as soon as possible
