High Pressure Concrete Line Pump

Brief introduction of EP high compress Concrete line Pump

It is major used for the high building pumping concrete. The power is bigger, and come the from the engine power.Max. Pumping height can match 300m.

EP High pressure concrete line pump feastures

1. Hydraulic system

This product USES the double pump, the double loop open type hydraulic system, the main pump oil circuit and the S valve swing oil circuit mutually independent, makes the system simple, the component life extension, the reliability is higher, and facilitates the fault judgment and the elimination.

The main hydraulic components used in the world famous brand.This hydraulic system also has the overflow valve protection, the ultra high pressure from time to time automatic pressure cuts off, the alarm system, simultaneously stirs the system to have the automatic positive and negative turns the function, these greatly enhanced the system reliability.

(3) the swing cylinder USES the constant pressure pump to supply oil, so that it has full time swing commutation, swing more powerful and energy saving function

(4) all pipelines are used cone seal or import rectangular seal, pipe joint sealing reliable.

2. Electronic control system

The prominent characteristic of concrete pump electric control system is advanced technology, simple and high reliability.

(1) using CAN bus communication, instead of many traditional time relay or other relays, than the second generation of PLC programming operation is more simple and convenient.Fully enclosed wiring harness, more friendly interface, stronger anti-interference ability.

(2) more than 90% of the electrical components are used in Japan omron company, mitsubishi corporation and other original imported parts, to ensure the reliability of the components.

(3) the use of remote control, reflect the intelligent products, users operate more convenient.

(4) proximity switch to pump automatic reversing.

3. Mechanical systems

1) hopper, S valve key mechanical components design, such as program of its stress state is obtained by using the i-deas, stiffness, stress concentration status subdivision mesh finite element calculation, design of the hopper, S valve structure have good stiffness and manufacturability, to avoid the similar products in high-level transportation hopper deformation and S valve shaft breaking phenomenon.Put on the market more than 2000 sets, hopper and S valve has never been abnormal.

(2) mixing mechanism with a unique structure, the hydraulic motor and the mixing bearing seat completely isolated, even if the mixing seal wear leakage slurry, also will not affect the hydraulic motor.Automatic forward and reverse rotation of stirring mechanism and anti-wear blade can effectively prevent the occurrence of clogging

(3) glasses plate, cutting ring and other wear parts, after continuous technical breakthrough, long service life, the best pumping state, its life can reach 70,000 square.

4. Lubricating system

The lubrication system adopts the centralized automatic lubrication system with patented technology, and the pressure filter is set at the outlet of the lubrication pump to ensure the reliability of the lubrication system.

5. Cooling system

Big radiator using forced air cooling device with water-cooled radiator, ensure that the hydraulic system of working oil temperature control under 60 ℃, thus guarantee the host hydraulic system is in normal working condition.

6. Power systems

The engine Mc07.31-50-228kw and dachaidaoeitz bf6m1013-174kw with sinotruk chassis Man technology have strong power, excellent performance and high reliability.Equipped with PLC electronic control throttle system, automatic rise speed, idle speed, environmental protection and economic.
