Concrete pump can transport high-floor and long-distance features, can be widely used in high-rise buildings, coal mines, mines, tunnels, railways, highways, bridges and culverts, ports, water conservancy, electric power, defense engineering and other concrete works is a highly efficient concrete Pumping machinery. Mining concrete pump concrete construction in winter so from the plastic state into a hard stone as a solid, mainly after the cement hydration gel, gel made of freshly poured concrete in the water can be divided into two parts: Part of the adsorbed on the surface of the material particles and the capillary water, this part of the water can hydrate the cement particles Power system uses well-known brand motor; double pump dual circuit hydraulic system, small impact, high reliability; with anti Pump function, help to eliminate the plugging tube failure in time, and can stop for a short time to be expected; Mining concrete pump uses advanced S tube distribution valve, which can automatically compensate for wear gap, good sealing performance; wear-resistant alloy plate and cutting ring , Long service life; long stroke of the material cylinder, extending the life of the material cylinder and piston; hopper optimized design, better suction performance, higher efficiency; automatic centralized lubrication system to ensure effective lubrication of the machine operation; The user-friendly design of the product makes the operation more convenient and easier to maintain. For the warm floor construction needs to pump fine aggregate concrete, and the traditional mortar pump can not complete the pumping, mining concrete pump successfully solved this problem, the pump uses the most advanced S-tube valve structure, double piston, Full hydraulic control, with the system running smoothly, easy operation and maintenance features less. Suitable for large-scale and high-efficiency construction of fine-grained concrete filled layer or mortar filled layer in floor heating project, besides pumping fine aggregate concrete, it can also pump mortar for ground and wall construction. Special construction of mine concrete pump performance characteristics of the use of advanced s valve commutation, to meet the delivery of fine stone concrete; glass plate and cutting ring with high hardness wear-resistant alloy material, longer life, with mine concrete pump running in the best Working conditions Mining concrete pump motor total power decline, the use of 45KW main motor and 22KW auxiliary motor, the total power is 77KW, only the main motor uses a 2 (2960 rev / min) motor. Than the traditional HBT6013 concrete pump 110KW motor power 33KW less. Soft start and stop function instead of a separate star - delta start or soft start mode, variable frequency speed controller start better, make the motor start and stop smooth, reducing the impact on the power grid and hydraulic equipment. Quantitative pumps can be used instead of variable pumps, reducing the cost of hydraulic equipment. Improve the power factor, improve the motor power quality, the motor power and the actual load to match the system to achieve the purpose of energy-saving operation. Eliminate the pump surge phenomenon, the pump is running in the best condition. Fault diagnosis function overcurrent, overvoltage, undervoltage, overheating, overload and so on. Pumping process, the feed inlet and discharge port seal is by close contact between the gate and the valve to achieve, the gate can not be a result of the seal can not be completed in time. Fine stone concrete pump when the rake is not in place, the pump has begun to change direction, resulting in part of the concrete from the suction port back to the hopper, so that the concrete material in the duct can not form a normal pump state, repeated many times Blocking occurs. In the middle of the end surface of the upper cylinder seat of the slide valve cylinder is an oil inlet and return oil chamber, and two damping holes are arranged around the cavity (generally two groups), each group of holes is connected to a cone valve with a spring, Oil cylinder piston end, a protruding shaft head, when the cylinder rod lift near the end of the stroke, the shaft head into the cylinder seat volume chamber, this time closed back to the oil circuit, oil return pressure moment to increase the safety of mining concrete pump.
