Critical component configuration of ZOOMWOL concrete pump
-1: main oil pump
The main pump is the core of the concrete pump hydraulic system, like the heart of the human body.
The technical performance and reliability of main pump have a direct influence on concrete pump. Therefore, we should carefully choose the supporting supplier of the main pump.
The main pump selected by ZOOMWOLF concrete pump has always been a world-class brand, such as Germany REXROTH.
-2: Hydraulic valves
In the hydraulic system, the function of the hydraulic valve is to control the pressure, flow and direction of oil flow in the oil path according to the design logic, and distribute the pressure oil delivered from the pump to each actuator or to protect the system from overpressure. Its importance is self-evident: if a hydraulic valve does not work properly, it will cause the whole hydraulic system to work abnormal or even paralyzed!
In order to ensure reliability, ZOOMWOLF has selected hydraulic valves of world-class brands in the hydraulic system of concrete pump, such as REXROTH in Germany and VICKERS in the United States.
-3: the radiator
Adopt controllable full flow air cooling to ensure the hydraulic system works under the optimal oil temperature of 60℃ or so.
Even in the highlands, there is no shortage of water or freezing.
The importance of the radiator is to reduce the working temperature of the hydraulic system timely and effectively to ensure that the hydraulic components do not fail due to excessive temperature.
-4: oil tank
Role of hydraulic tank in hydraulic system: storage of hydraulic oil.
In the open system, the hydraulic tank also acts as a buffer to cool the hydraulic oil, because after cooling by the radiator, the hydraulic oil flows back to the tank for natural cooling. In addition to the above basic functions, add filters, vacuum pressure gauge, level gauge, thermometer on the tank body, can filter the hydraulic oil to maintain cleanliness, show whether the amount of oil is enough, whether the temperature is normal.
-5: Manual reversing valve
In the ZOOMWOLF concrete pump, the start or stop of the mixing motor is controlled by manual reversing valve. The manual reversing integrated overflow valve for concrete pumps, GALTECH, Italy, is selected to simplify system components while greatly improving them reliability.
-6: the PLC
Using programmable controller(PLC) to replace the traditional relay circuit not only simplifies the internal layout of the control cabinet, but also improves the reliability of the circuit.
ZOOMWOLF concrete pump selects PLC hardware from world-class brands, such as SIEMENS of Germany and MITSUBISHI of Japan. The concrete pump is precisely controlled by implanting control program, and multiple automatic protection modes such as temperature, pressure, speed and oil level are set in the program.
-7: Electric cabinet and electrical components
In the constitution of concrete pump, electric control system has the function of "commander" by means of man-machine interface. Concrete pump all the action, there are issued here "command signal" to implement.
In order to ensure the reliability of the system, ZOOMWOLF electrical system design and component selection have been optimized.
In terms of design, simplicity and safety are the preconditions. In the selection of electrical components, reliability ranks the first A. Therefore, in ZOOMWOLF concrete pump electrical control system, more than 90% of the components are used in reliable performance international first-class brand products, such as France Schneider, Germany Siemens, Japan Omron, etc.
-8: diesel engine and ECU
ZOOMWOLF concrete pump diesel engine brand selection, give three reasons: brand influence,
performance and after-sales service.
Unless customers specify special orders for diesel engine brands, ZOOMWOLF concrete pumps
will choose German Deutz series products.
In the past two years, diesel engine control and concrete pump operation control are more
closely combined, forming an integrated "electronic control unit" ECU, gradually replacing the original discrete control mode.
-9: power
ZOOMWOLF concrete pump is divided into two series: motor drive and diesel drive. The first choice is 110kW for electric motor and 186kW for diesel engine.
-10: Non - contact commutation technique
For more than ten years, ZOOMWOLF concrete pump has been using electric control commutation technology. It is through the moving parts (concrete piston and piston rod) do not contact the proximity switch real-time detection of the limit position of the piston stroke to give electrical signals, and then by the electrical system to control the hydraulic system to complete the reversing process. This technology is simple and reliable, with a very low failure rate and easy to judge and eliminate once the fault occurs. We call it "non-contact commutation technique".
