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.

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

First, the sustainable use of

The use of concrete mixing plant scrap concrete products that do a variety of precast concrete products. Such recycling scrap concrete method is relatively the most economical and practical method, due to the general precast concrete products for concrete grade is not required, and the production is relatively simple, only need to be watered template on the line. This method of processing scrap concrete is very simple, just put together different scrap concrete poured on a good template to prepare in advance, and then put under a ventilated environment to dry.

Second, for non-basic construction

The scrap concrete products are sold in some remote mountainous areas targeted farmers at home were occupied. There are a lot of these intermediary companies from the commercial concrete stirring station recycling all kinds of scrap concrete, then sold these specialized areas.

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.

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.

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.

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.

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.

Usually cement tank 100T / cement silo is not a sufficient amount of loading. Regular use of bulk cement tank users are aware, generally do not exist in much cement cement tank, one with a use that many, cement tanker can come twice a day, sufficient, and second, because there is a water-absorbent cement easy bonding agglomeration, general 80T, 100T cement tank are generally semi-warehouse use, it will not be filled slowly.

So ,Why 100T cement cans not enough of it?

Actually, this is from a design point of view, the general design is based on cement tank cement under tight state design, cement bulk density refers to cement in the natural state (including the space) mass per unit volume in tonnes / cubic representation. Cement bulk density can be divided into two kinds of density and bulk density close state under the loose state. However, our cement tanker pull cement are loose state, different densities (containing voids), thereby giving rise to a sufficient amount of the issue can not be installed, generally semi-warehouse capacity is enough to use.
