How to Maintain Small Concrete Mixer Pump

 The concrete mixer and pump for sale has concrete mixing and pumping in one and is welded on a frame with axles, which is pulled by a small truck or small loader to move quickly between several construction sites or between multiple construction points on the same construction site,thus greatly shortening the interval time.

It only needs 4 people and a forklift for feeding, which fully automatically mix and pump the concrete. Take C20 concrete as an example. The proportion of concrete raw materials mixed by the mixing pump is one forklift stone + one forklift sand + two packs of cement.

Use the remote control to operate the mixing and and the drum mixer will mix a tank of material within 15 seconds, and then automatically pump the mixed concrete through a 3-meter-long, 125-mm-diameter pipeline to the foundation of the house. The whole operation is quite simple and easy, which greatly reduces labor cost. Then how to maintain this powerful concrete mixing pump?

1. Always check the oil level and oil quality of the hydraulic oil. The oil quality should be light and transparent, without emulsification or turbidity, otherwise it should be replaced.

2. Fill up the grease, empty the water tank and then load it up.

3. Check the piston of the concrete pump. The piston should be well sealed and no mortar penetrates into the water tank.

4. Check the working condition of the lubrication system. You should be able to see that the indicator rod of the progressive oil separator moves back and forth, and the lubricating oil at the lubrication points such as the bearing position of the S-tube swing arm end and the bearing position of the stirring shaft should overflow slightly.

5. Check whether the function of each electrical component is normal.

6. Check whether the reversing of the distribution valve and the forward and reverse rotation of the stirring device are working properly.

7. Check the outside of the cooler. If there is any dirt, it should be cleaned immediately, otherwise it will easily cause the oil temperature to overheat.

8. Check the indication of the vacuum gauge. It should be in the green area, and it is strictly forbidden to exceed 0.04. Generally, the vacuum degree of oil suction should be less than 0.02Mpa, and the vacuum value of oil return pressure should be less than 0.35Mpa.

9. Check the wear degree of the concrete pipeline by tapping, and check whether the joints of each pipeline are sealed and in good condition.

10. Check whether there is oil leakage or oil leakage in the hydraulic system of the small concrete mixer pump.

How to Buy and Debug Concrete Mixing Pump

 The concrete mixing pump undertakes the dual functions of mixing and pumping. Compared with a single mixer or concrete pump, its workload is definitely twice or even several times that of a single-function device.

The construction process of the concrete mixer and pump is followed by installation, piping arrangement, inspection, forklift feeding, material loading, mixer mixing, conveying, pumping concrete to the designated position for construction - cleaning after construction is completed.

It also has two types: electrical and diesel one. The diesel concrete mixing pump is upgraded on the basis of full hydraulic pressure. The motor drive is changed to diesel engine drive, and the output torque is larger. The motor speed is only 1500 rpm. The output oil volume of the oil pump is increased by 20%. The drum speed, hopper lifting speed and pumping speed are all accelerated by 20% with the same configuration.

When you buy concrete mixer pump trailer, the configuration of the product cannot be ignored. It is usually necessary to observe the frame thickness, workmanship and materials of other key parts of the concrete pump.

When selecting parts, the material of the hydraulic hose and the lubricating copper pipe is as important as the "main oil pump", the heart of the delivery pump. Once a problem occurs with one hose, it will affect the normal operation of the entire hydraulic system, resulting in mechanical failure.

AFTER BUYING A CONCRETE MIXER PUMP TRAILER, HOW TO DEBUT IT?

1. Various components, accessories and random items of various debugging equipment should be fully equipped according to the standard.

2. Prepare hydraulic oil and lubricating grease, and the oil quality of hydraulic oil should meet the requirements.

3. Fill hydraulic oil, fuel oil, lubricating oil and cooling water according to the regulations, and at the same time, the hydraulic oil should be added to the specified oil level.

4. Check, debug and test the concrete mixer and pump to make it enter the normal working condition. At the same time, the hydraulic system should meet the standard after debugging.

5. The pipe diameter of the concrete pump for debugging is 125.

6. The experimental concrete should meet the standard.

7. The equipment should be placed on a flat and solid ground.

Why Do Americans Like Using Concrete Boom Pump Truck with Multi-axle Chassis

 With technological innovation and the use of high-strength steel, China can currently achieve 3-axle 47 meter pump truck and 4-axle 60-meter pump trucks. However, in terms of stability and durability, more axles within a reasonable range is of course the better. In fact, the 4-axle 47 meter pump truck us is more reliable than 3-axle 47meter concrete pump.

In addition to its overweight limit being raised, for pump trucks that often drive on paved roads, the more axles, the smaller the pressure assigned to each tire, which also plays a good role in protecting the road and avoiding overloading. Moreover, the more axles there are, the larger the pressure area of the body on the chassis, which can also relieve the fatigue deformation of the chassis girder material.

However, the more axles the chassis has, the more expensive the price will be. From the customer's point of view, of course, the fewer axles the better. Therefore, in the domestic market, a 3-axle 49-meter pump truck like this is very popular with consumers, because in this way, buying a long boom pump truck can save a lot of cost.

For Americans, the concrete pump trucks with a length of more than 50 meters should start with 6 axles. For example, the 63-meter boom pump truck from Alliance in the United States is based on a MACK 7-axle universal truck chassis. Since the length of the body is sufficient, the boom of this car does not need to be extended to the cab, and the conventional RZ-type boom structure is adopted.

Another is 10-axle 70 meter concrete boom pump truck is the longest boom pump truck from Putzmeister. This pump truck does not use a conventional heavy truck chassis, but adopts the design of a tractor. Among them, the tractor has 5 axles, and the rear bodywork also provides 5 axles. Why do Americans like using multi-axle chassis?

Due to the very strict overrun standards in the United States, it is very unfriendly to concrete pump trucks. The weight of the pump truck is very large, therefore, to meet the overrun criteria, more axles must be added, thereby reducing the overrun assigned to each axle.

Compared with domestic short-axle long-boom pump trucks, it is really troublesome for this kind of ultra-long chassis concrete boom pump truck to enter and leave the construction site. Its turning radius is large, and the space requirements for the construction site are larger, so it is also very inconvenient to use. If it were you, with the same boom length, which type of chassis would you choose?

An Overview of Tow Behiend Concrete Pump

 In recent years, the upgrading of concrete pumps has developed rapidly. From concrete pump trailer, truck mounted concrete pump, to boom pumps, he functions have been gradually improved. However, due to the limitation of the height of the boom and the safety of the outriggers, it is very restricted in some narrow construction areas, and only the tow behind concrete pump is used.

The concrete line pump is the cheapest among the three, and there are electrical and diesel ones. The difference lies in whether the power source of the hydraulic system is provided by the motor or by the diesel engine.

The running noise of the electrical concrete pump is relatively small while the diesel concrete pump is relatively flexible when working. If it is in a place where there is no sufficient power supply, it is of course safer to choose a diesel concrete pump trailer.

There are many factors that determine the pumping distance of the tow behind concrete pump. The first is the maximum pumping pressure of the equipment. The maximum pumping pressure directly determines the farthest pumping height and horizontal distance. Second, the properties of concrete can also affect how far it can be pumped. For the same machine, concrete with low strength can be pumped farther than concrete with high strength.

The pump pipe of the concrete line pump is usually used for high-rise or long-term concrete pouring projects. The conventional length is 3 meters, 2 meters, 1 meter, 0.5 meters or even shorter as the regulating tube.

When there is no difficult operation, DN125 high pressure or low pressure can be selected. Because of the pressure bearing, the material is mostly 20# steel. The steel pipe of 20# steel has toughness and is not easy to burst.

When concrete is pump horizontally and the distance is not very far, straight seam pipe can be used, which is low cost. Of course, it is recommended to use seamless pump pipe when the budget is sufficient.

The unique and creative open hydraulic system of Haomei mini concrete pump for sale integrates the advantages of open and closed type, with high system efficiency, good heat dissipation and stable operation. The hydraulic control part adopts the products from the first-line brands. The advanced S-pipe valve system has good sealing performance, simple structure and convenient replacement of wearing parts. Welcome to leave message below to inquire what you need.

A Highlight of Self Loading Transit Mixer

 The self loading transit mixer has self loading, self mixing, transportation and discharging in one, which is widely used in road building, house, ground hardening, workshop,etc. It reduces labor and costs by 30% compared with traditional operating machinery, and is also the first choice for rental tools in the construction rental market.

The main structure of the self-loading mixer truck consists of a walking chassis, an engine, a hydraulic torque converter, front and rear double drive axles, a feeding device, a feeding hopper, a discharging hopper, an extended discharging hopper, a frame, a mixing drum, and a special reducer for mixing, hydraulic system, electronic control system, automatic water supply system and other components.

The mixing drum is a concrete loading container made of high-quality wear-resistant steel sheet. The inner wall of the mixing drum is welded with special-shaped helical blades for automatic loading and unloading of concrete. As it rotates, the concrete moves along the helical direction of the blades and is stirred during continuous lifting and rotation.

Double helical blades are set on the inner wall of the mixing drum of the self loading concrete mixer truck. Forward rotation is for feeding and concrete mixing; otherwise, under the push of the spiral blades, the concrete is discharged from the discharge port.

During the operation of the self mixing concrete truck, the material is usually shoveled into the upper hopper first, and then the upper hopper is gradually lifted to the entrance of the mixing tank.

During the lifting process, the rear door of the upper hopper is closed to prevent the material from leaking. When it is lifted to the highest position, the rear door is opened, and the material can fall into the mixing tank under the action of its own gravity to complete the feeding action.

The pressurized water tank is the main water tank used by the current self mixing concrete truck manufacturers. This type of water tank is mostly made of steel because it bears a certain pressure. Generally, the cylinder body is made of Q235 steel plate of 3-4mm, and the head is made of Q235 steel plate of 4-5mm or Q235 steel plate of 4mm. It is easy to rust inside and needs to be coated for protection.
