What are the types of concrete pumps?

 The concrete delivery pump includes a pump body and a delivery pipe. It is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly used in house construction, bridge, and tunnel construction. With the rapid advancement of urbanization and the rapid development of urban buildings, the demand for concrete pumps is gradually increasing. YG concrete pump manufacturer offers many types of concrete pumps. We will introduce you to the machine details.

Concrete delivery pump composition

The concrete delivery pump adopts the electric motor or diesel engine to drive the pumping system, and the delivery volume of the concrete delivery pump can be automatically adjusted through the constant power control of the hydraulic system, and the concrete delivery volume can be selected by manual control. The pumping system is mainly composed of a hopper, a mixing mechanism, a concrete distribution valve, a concrete delivery cylinder, a washing room, and a main oil cylinder.

Working principle of concrete pump

When the pressure oil of the hydraulic system enters the main oil cylinder, the piston rod extends, and at the same time, the pressure oil passing through the connecting pipe of the sealing circuit makes the other piston rod retract. When the concrete conveying piston connected to the piston rod of the main oil cylinder retracts, it produces self-priming in the conveying cylinder, and the concrete in the hopper is sucked into the conveying cylinder through the suction port of the slide valve under the action of atmospheric pressure and the boost of the mixing blade. At the same time, under the action of oil pressure, the other main oil cylinder pushes the piston rod of the main oil cylinder out and at the same time pushes the concrete piston to press out the concrete in the delivery cylinder, and enters the concrete delivery pipe through the Y-shaped pipe of the delivery port of the slide valve. After the action is completed, the system automatically reverses the direction so that the pressure oil enters the other main oil cylinder to complete another suction and delivery stroke of different delivery cylinders. Repeatedly, the concrete in the hopper is continuously sucked and pressed out of the delivery cylinder and reaches the operation point through the Y-shaped pipe and the pipeline connected to the outlet to complete the pumping operation.

Types of Concrete Pumps

There are many types of concrete delivery pumps, which can be divided into the following categories according to different methods.

1. According to the way of movement: according to whether it can be moved, concrete delivery pumps can be divided into fixed concrete delivery pumps and vehicle-mounted concrete delivery pumps.

The stationary concrete delivery pump has no chassis and needs to be towed to move, while the vehicle-mounted mobile concrete pump has its own independent chassis, so it can be moved directly.

2. According to valves: According to the different valves of concrete pumps, concrete delivery pumps can be divided into tubular valve concrete delivery pumps and rotary valve concrete delivery pumps. Different design forms have different advantages and disadvantages.

3. According to the size of the pump: according to the size of the concrete pump, the concrete pump can be divided into mini concrete pump, small concrete pump, medium concrete delivery pump, and large concrete delivery pump. Usually, depending on the size of the project, concrete pumps of different sizes and models can be purchased for construction.

4. Classified according to the driving method of concrete pumps: there are piston types and extrusion types, and most of them are piston types at present. In addition, there are hydraulic diaphragm and air tank pumps.

In addition, there is a concrete mixer with pump.

Road Construction Machine- Asphalt Coring Drilling Equipment

 What is a pavement coring machine

 

A pavement coring machine is often needed equipment in pavement engineering, usually used for cement pavement and asphalt pavement coring work. It is also mostly used for the complete acceptance of highway projects and scientific research work that requires coring. The asphalt coring machine is mainly used for compressive and flexural tests of cement concrete, asphalt concrete, and limestone foundations such as roads, airports, ports, docks, and dams. The core sample can reach 700mm.

 

Why Use a Pavement Coring Machine?

 

The common pavement form is semi-rigid base asphalt pavement, and the bond between the asphalt layer and the semi-rigid base is weak. Because the bonding between the asphalt layer and the semi-rigid base layer is weak, this method can easily cause the core sample to break at the weak point where the asphalt layer and the semi-rigid base layer are connected, resulting in damage to the core sample, increasing the difficulty and strength of the work, and bringing great impact to the follow-up work. trouble. Therefore, we propose a new road pavement coring machine.

What are the uses of the road coring machine?

 

A pavement coring machine is also called concrete drilling and coring machine. It is a kind of equipment widely used in the construction industry. Flexural test. The instrument adopts high-speed cutting technology and is matched with thin-walled diamond drill bits. It is widely used in drilling and coring in the fields of engineering construction, municipal engineering, equipment installation engineering, and construction quality inspection engineering. It also can equip with an asphalt crack sealing machine, road line marking machine, Shot Blasting Machine, and other equipment.

 

Basic knowledge of drilling and coring on asphalt pavement

 

1. Rack: The rack is installed on the column, and four adjusting screws are installed on the base.

2. Sliding seat: set on the column, the internal gear and the rack on the column form a gear pair, and turn the feed handle to make the sliding seat move up and down along the column.

3. Gearbox: it is fixed on the sliding seat, and the drill bit is installed on the main shaft, which moves along with the sliding seat to achieve the purpose of drilling.

Precautions for road gasoline drilling and coring machine

1. When drilling, the feeding speed should be uniform, about 3 to 5 cm/min. If the drill bit is found to be stuck, the feeding speed can be appropriately reduced. If necessary, the drill bit can be raised for a section and then drilled slowly. Avoid hard drilling, so as not to damage the drill bit and the machine.

2. It needs to maintain sufficient water cooling throughout the drilling process.

3. At the end of drilling, the machine can only be stopped when the drill bit is separated from the workpiece.

4. During the drilling process, do not overload. When the temperature of the motor exceeds 70°C (it feels hot to the touch), the loading force should be reduced and a new drill bit should be replaced.

 

 

Maintenance and Inspection of Pavement Gasoline Drilling and Coring Machine

1. Regularly check the connection of each component, and adjust it in time if there is any looseness.

2. When the drill bit is installed, calcium-based grease should be added to the two threads.

3. After the drilling is completed, clean all parts of the drilling rig, and add lubricating oil to the column and rack.

4. Change the grease in the gearbox every six months.

What are the types of steel pipe shrinking machines？

 What is a shrinking machine?

The pipe shrinking machine is a device for expanding and shrinking the end face of the pipe fittings. It is ideal equipment for processing and forming pipe fittings such as water pipes, automobile oil pipes, air pipes, water pipes, and air-conditioning pipes. According to the mold, the pipe fittings can be processed into convex, concave, long, flat, square, oblique, V-shaped, open bend, flat bend, and other shapes. The pipe shrinking machine is the best equipment for pipe end processing such as pipe expansion, shrinkage, bulging, and upset.

Type of shrinking machine

YG shrinking machine manufacturer offers three different types of shrinking machines for sale. They are hose crimping machines, shrinking machines, and tapered shrinking machines respectively.

Hose crimping machine

Driven by the motor, the oil pump outputs hydraulic oil and pushes the plunger in the crimping cylinder to move forward, so that the plunger and the two inner taper sleeves on the front cylinder head push the mold base with symmetrical tapered surfaces to shrink radially, realizing module alignment. Hose crimping. When the shrinkage reaches the setting value of the scale, the crimping will automatically stop. After the electromagnetic reversing valve is reversed, the hydraulic oil enters the two mold opening cylinders, pushing the crimping plunger to move in the opposite direction, and the mold base drives the module to recover under the action of the spring.

The crimping mechanism is the working mechanism of the tube locking machine. The pressure sleeve realizes reciprocating motion under the drive of the cylinder piston, and continuously compresses and relaxes the spring pressure head fixed on the front plate. Put the installed joint into the proper position in the middle hole of the spring pressure head, start the motor, drive the oil pump to supply oil, and drive the piston of the oil cylinder to move forward by controlling the reversing of the electromagnetic reversing valve. , to compress the spring pressure head with the same taper to achieve the purpose of pressing. Press the mold opening button, and the piston drives the pressure sleeve to move in the opposite direction, and the spring pressure head is restored, and the hose joint can be taken out from the hose locking machine at this time.

Tube shrinking machine

The tube end forming machine is a multifunctional device for shrinking and flaring the pipe. It can realize the processing of the pipe by reducing or expanding the pipe end at the end of the pipe blank. By changing different molds, it can process the pipe into convex, concave, long and flat, square, oblique, V-shaped, open elbow, flat elbow, and other shapes.

Taper shrinking machine
