BKQ-40 Concrete pump

Product introduction:

Concrete conveying pump, also known as concrete pump, consists of pump body and conveying pipe. It is a machine that uses pressure to continuously transport concrete along the pipeline. It is mainly used in building construction, bridge and tunnel construction. It is mainly divided into gate valve concrete pump and S valve concrete pump. The other is a pump truck which is composed of a pump body mounted on a car chassis and equipped with a retractable or flexing cloth rod.

1.Inhalation rate

One-pump dual-circuit open system: The main cylinder is immobile at the moment of the reversing of the swing cylinder; the main cylinder starts to work after the reversing is in place, thereby ensuring that all the concrete in the cylinder is transported to the foundation.

Dual circuit separate oil supply system: two motors drive two oil pumps to supply oil to their respective systems, and work simultaneously at the moment of commutation. The main oil cylinder has already started to push when the distribution oil tank is not in place, causing some concrete to be pushed back. In the hopper, the suction efficiency is reduced.

2. Energy saving

One-pump dual-circuit open system: there is no problem of energy waste, the use of power resources is maximized, and energy saving is 10KW under the same pressure and displacement;

Dual circuit separate oil supply system: As long as the motor is started, the oil pump of the distribution oil cylinder is always working, and it is started with load (under pressure) every time, causing waste of energy and mechanical wear.

3. Security

One-pump dual-circuit open system: When the motor stops rotating, the system loses pressure and will not cause damage to the maintenance;

Dual circuit separate fuel supply system: When the motor stops rotating, the system pressure must be released, which is very dangerous for maintenance workers who are not very clear about the principle of the system.

Mixing valve system

hopper

Optimized design of the hopper to ensure good suction, equipped with grids of different specifications and different materials, and equipped with a vibrator

Mixing system hydraulic motor

The high torque hydraulic motor is used, and the system does not have the function of automatic reversal of overpressure, which effectively protects the hydraulic motor and can automatically eliminate the card phenomenon.

Blender

High abrasion resistance, large blade stirring, concrete should not be precipitated, which is conducive to suction.

S-tube swing valve

It has the characteristics of smooth flow and low resistance. The wear surface is surfacing with high wear-resistant materials and the transmission parts are plated and wear-resistant, which avoids hopper deformation and S during high-level transportation of similar products

The valve breaks the shaft. The installation adopts the support and sealing isolation structure, which improves the service life.

Product configuration:

First, the hydraulic system

The application of the new hydraulic control commutation technology makes the pumping work more reliable and the failure rate of the hydraulic system is lower; the special valve of the hydraulic control system is equipped, which has low energy consumption and low impact, and prolongs service life.

Second, the power system

The motor fine stone pump adopts well-known brands at home and abroad, Hebei Electric, Siemens Beide Motor, and the diesel fine stone pump uses the low energy consumption and high efficiency Yuchai brand.

Third, the main oil pump

The joint-venture brand constant power variable displacement plunger pump is adopted, and the constant power control effectively prevents the motor and diesel engine from being overloaded, and bears higher pressure and load than the conventional gear pump.

Fourth, the cooling system

The air-cooled or water-cooled dual cooling system is not only suitable for high-temperature climates but also for severe cold climates. It effectively controls the oil temperature of the hydraulic system and ensures the safety and reliability of equipment operation.

Five, electronic control system

The main electrical appliances use Schneider, LS brand.

Six, hopper device

Increase the hopper volume and the fence is equipped with a vibration motor to meet the requirements of pumping fine stone concrete.

Seven, S pipe valve

S pipe valve is made of high-manganese steel as a whole. The wear-resistant surface is surfacing with anti-wear material, which has the advantages of high pressure resistance and wear resistance. The key shaft is made of alloy material for special surface treatment, which improves the wear resistance and fatigue strength.

Eight glasses plate, cutting ring

The glasses plate and cutting ring are made of hard alloy inlay, which is durable.

Nine, hydraulic pipe joints

The hose is imported from Italy and the joint is Eaton. The hose joint assembly is provided by Eaton as a complete set.

Ten, centralized lubrication system

A plunger pump injects the lubricant into the main line and distributes the lubricant to the lubrication points through a dispenser. "Point-to-point" lubrication protects critical components from wear.
