Concrete Pump Main motor failure Solution

HAOMEI Concrete pump machinery can be common to many, usually the main problem is in the concrete pump rotational speed of the main motor can not reach or can not start,(used concrete pump and mixer) the problem is particularly troubled for many construction business, The following article will teach us how to Solve Concrete Pump Main motor failure:
We must first understand that the main concrete pump motor does not start up or launched, first check whether the closed QF1, QF1 if unable to close, you should check circuit troubleshooting. If you press the start button the main motor, motor shell operation, but less than the required speed, then you should first check whether the normal power supply voltage, the transformer capacity is sufficient, and then determine whether the diameter of the supply line to meet the requirements, ensure that the voltage drop within a predetermined range within you can relieve the problem. In addition, if the improper operation of the hydraulic system will cause difficulty in starting, so that the pump should first check the power, and then check the stirring motor operating handle is in the neutral position, (concrete pump mixer truck)the pumping button is closed. If you still can not start the pump pressure is necessary to check the master control solenoid valve is normal, should ensure that when starting the main pump in unloading state.
Finally, remind the construction business, there is an important question is, (concrete pump with mixer)concrete pump master cylinder top, if not the master cylinder should check the commutation limit switch and its associated line; if normal, you should check the master cylinder operation control solenoid valves and hydraulic valve if stuck. Also check the hydraulic oil pressure hydraulic valve control is adequate, if not enough can not promote the spool movement, the cylinder will not change direction.

concrete batching plant fault diagnosis

Observation inquiry method
concrete batching plant equipment maintenance can be carried out according to the useful life of equipment and the associated preliminary analysis of the model, ask the user for repair and inspection done, and then make a thorough understanding and careful observation of the phenomenon of failure, then make judgments, focus wearing parts easy to wear, reliability.
Hearing Law
When the equipment is running, it will be issued regularly but noisy sound, if the equipment fails, it will produce abnormal sound. When servicing, you can let the device run under different conditions, equipment failure and auscultation, for example, the crankshaft and connecting rod mechanism, you can use the pole rods auscultation auscultation abnormal sound; on the card keyway gap at the role and reaction , irregular abnormal sound.(concrete plant)
Touch Method
Maintenance personnel can use the handle to be feeling for equipment failure. For example: the emergence of the motor overheating; to touch the pump outlet hose, you can feel the water pressure is passive, so the case will show that the pump is working; practical aspects of checking the tightness of the belt, the specific surface friction wear, etc; seal not very good axis member, there will be noticeable vibration running, trembling or other phenomena, prove whether mechanical equipment is working properly.
Olfactory law
If the work station concrete mixing plant equipment appeared overload, there will be odor, so the work can be carried out with a sense of smell. For example: appears on the operation of the device mechanical overload, if the temperature rises, it will produce odor; if non-metallic materials exudes the smell of burning, it indicates that the wire is damaged.(batching plant)
Substitution method
The so-called replacement method is to use a qualified or assembly parts, damaged parts will appear to be replaced, for wearing parts and grindability member periodically inspected and replaced. For part of the vulnerability, but unfavorable

How to solve the concrete batch plant stop working

How to solve the concrete batch plant stop working ?HAOMEI to teach you.
1. concrete mixer overload caused by the agitator shaft is stopped, simply adjust the feed rate, discharged excess material can reduce the agitator shaft load.(concrete batching plant supplier)
2. The side with the blade off the inner wall of catching the material in front of the agitator shaft is stopped, there is often a sharp squeal, this is the case, the need to immediately stop inspection, artificial exclude foreign body, re-adjust the concrete mixer or mixing blade side blade gap and the tank wall.(construction machine concrete batching plant)
3. The electric concrete mixers motor belt is too loose a case, simply adjust after the shutdown concrete mixer motor drive belt tension can be.

New concrete mixing station run-in period Precautions

Purchase new concrete mixing plant became operational when the influence of the new machine parts processing, assembly and transfers and other factors, the friction surface roughness, the smaller the area of ​​contact with the surface, uneven surface pressure state, there will be a period of transition. The newly-purchased commodity concrete mixing station may experience some kind of situation? How should we handle it? The following aspects of China for this concrete network Xiaobian for you a brief run-down concrete mixing station precautions period.
Wear faster due to the dry concrete batching plants Stirring stations and other accessories parts processing, assembly and transfers and other factors, the friction surface roughness, with a smaller surface contact area, pressure state surface unevenness. The machine running the process, the concave and convex portions of the surface of the part are mutually fitted friction, wear down to the metal debris, and as abrasives, friction continued participation, but also accelerated the wear part mating surfaces. Thus, the run-in period likely to cause parts (especially mating surface) of wear, wear faster. In this case, if the overload operation, it may lead to the destruction of parts, occurs early failure. Such as: hzs concrete batching plant host leaves.
Poor lubrication due to the commercial concrete mixing station with a small gap new assembly parts, and because of assembly reasons, it is difficult to ensure uniformity with the gap, the lubricant (grease) in the friction surface is not easy to form a uniform film, to prohibit wear . Thereby reducing the effectiveness of lubrication, resulting in the early parts of abnormal wear. It will cause serious friction with precision surface scratches or bite, leading to failure.
Parts loosening commercial concrete mixing plant new processing and assembly, there are deviations with the size and geometry of the initial application, due to shock, vibration, and other alternating load, and the effect of thermal deformation and other factors, coupled with excessive wear fast and other reasons, would have been easy to make the fastening parts loose.

Concrete mixers need to have what conditions

As one of the two essential elements of the concrete mixing plant, concrete mixer has a vital role. Then, using the concrete mixer needs to have what conditions?
First, a small concrete mixer should be set on a flat place, so that the tire is in floating position in order to avoid loosening during startup. Stirring is preferably carried out prior to commissioning empty, ready to work. Note that, when commissioning test mix drum speed is appropriate, under normal circumstances, empty after loading speed slightly faster than the turn 2-3, such as a difference of more, should be adjusted to move the ratio of wheel and drive wheel.
self-loading concrete mixer
Second, before concrete mixer machine working to carefully check each part to see if the transmission clutches and brakes are flexible and reliable, wire rope for damage, whether good track pulley, Accessible and other parts of lubrication, etc. around. Confirm no problem and then boot up.
Third, if during the boot process, if found to electrical or mechanical failure, it should be discharged more than expected, and other troubleshooting and then start running. Of course, when used, should always check to prevent the occurrence of accidents.
Finally, the concrete mixer after use, wind up its power and lock the switch control box, should not forget to clean up, clean health grounds, allowing machinery to keep clean.

The risk of using second-hand cement silo

In a market economy, many investors generally have a minimum investment return for the maximum benefit of the heart, some investors Shuaqi cleverness, playing the selection of used equipment abacus, in this era of economic stress, much of this policy respected, I also considered feasible, but it is not absolute, in a number of important projects in the province can save, not to the province or to be taken seriously in concrete batching mixing plant cement silo, too, the use of second-hand bulk cement Although the warehouse can save a lot of costs in the short term, but long-term it seems risky.
hot concrete batching plant
In concrete mixing plant production process, the use of second-hand bulk cement silo | cement tank is very obvious because the new price of bulk cement silo is in the million level, however, the emergence of second-hand bulk cement tank, it replaces the new bulk cement tank. , thereby reducing the expenditure of money. Many businessmen in order to obtain illegal profits. Because in the face of it, second-hand bulk cement bulk cement tank with a new outer edge of the tank appears to be not much different.
hzs35 cheap concrete batching plant
But you know the dangers of second-hand bulk cement silo it? A container, how to look is not important, important is the internal environment, the harm of second-hand bulk cement tank, is often the root cause of cement and other materials change. First, we can know that a good quality bulk cement tank, to prevent caking his, as well as dust, moisture function is durable. But if we use an unknown second-hand bulk cement tank, which prevents agglomeration, such as the original protection with the use of frequency and thus also declining, leading to prevent caking and other functions weakened or even failure, when we buy after the second-hand bulk cement tank, and thus long-term cement tank to accommodate the new system, the consequences can be associated with knowledge: one leads to cement agglomeration, resulting in waste of raw materials, but the cement blocks for environmental reasons, such as air and deterioration. The end result is often a cause acceptance problems. Finally, it can not lead to acceptance by the inspectors, bringing huge economic losses. So that both sides honor damaged.
Various statements explained the harm of second-hand bulk cement silo as a smart investor, I think it will not be reduced due to less expenditure on the use of bulk cement tank used in this regard. Once emerged in these details results jerry behavior often leads to disastrous is therefore not recommended to use innovative engineers used bulk cement tank.
