Ruibao independent research and development: sewage dedicated full liquid heat pump 5 evaporator; 6 economizer; 7 intelligent sewage resistance machine; 8 ~ 19 tangential valve; Cooling principle: tangential valves 9,10,13,14 open, 8,11,12,15 is closed, the refrigerant absorbs heat in the evaporator evaporation, the system made of 7 ℃ cold water into the room to use, the refrigerant then Compressor compressed into high temperature and pressure superheated steam into the condenser, remove the heat from the sewage and back to the sewage trunk. Heating principle: tangential valves 9,10,13,14 closed, 8,11,12,15 open, the evaporator into a condenser, the condenser into an evaporator. The refrigerant absorbs the heat of the sewage in the evaporator and evaporates, and the sewage is returned to the trunk of the sewage. The refrigerant is compressed into high-temperature and high-pressure superheated steam into the condenser by the compressor to heat the circulating water to prepare hot water (temperature 45 ~ 50 ℃, high temperature 60 ℃). work process The sewage is promoted to a machine room by a sewage pump, after being filtered by a smart sewage anti-resistance machine, enters a sewage source heat pump unit; after being warmed (or cooled) by the heat pump unit, the sewage again flows through the intelligent sewage anti-resistance machine and carries the contaminants Back to the trunk of the sewage. Heat pump unit to the end of the system for cooling (or heating). Features Wastewater dedicated liquid-filled unit of the sewage side of the heat exchanger, the heat pipe material for the Navy copper. The unit uses six specialized technologies to improve unit performance. (1) Spray (falling film) evaporator, effectively improve the evaporation temperature of the unit; (2) dedicated jet pump in the state of no energy consumption, complete the system of continuous oil return, safe and reliable; (3) specially designed high-performance condenser, which can reduce the condensing temperature of the unit; (4) the use of two compressor technology (used in high temperature water source heat pump); (5) a unique configuration of the oil separator and flicker-type energy-saving device; (6) the use of low pressure booster technology - exclusive first. Among them, the spray evaporator + high-performance heat transfer tube + low-pressure booster technology = increase the evaporation temperature; Secondary compression technology + increase the evaporation temperature = increase the cooling capacity (Qc); Unique condenser design + high-performance heat transfer tube = lower condensation temperature; Reduce condensing temperature + selection of dedicated compressor volume ratio = lower compressor work (N). Applications This product is used in the direct system. It can be used with the self-developed sewage anti-friction machine. The energy-saving effect is more obvious, the COP value is significantly increased, and the initial investment cost and the operation cost can be reduced in the early stage.

Boom-type Concrete Pump Truck (Truck-mounted Concrete Pump with Foldable Booms) is developed on the basis of drawing on advanced domestic and foreign experience and using advanced modern computer simulation techniques to systematically analyze the effect of changes in various parameters like stress, displacement and natural frequency on the boom`s fatigue life.
Meantime, we optimized the design of the hydraulic system, adopted the latest free fluid technique and greatly lessened the impact of pumping commutation on the distributing boom. In the boom structure optimization and the hydraulic system design, we obtained many patents. The consummate control of product quality, perfect techniques of product manufacturing and strict procedures of quality inspection make the Pump Truck a leading product in China and an advanced product in the world. All the steel plates for the boom system are high-strength cold rolling steel plates made by the Swedish company SSAB. The yield strength of the plates exceeds 900Mpa, which ensures that the boom system has high strength and light weight. The boom system`s distributing pipe, landing legs, oil tank and so on have all received 100% stress-removing treatment after welding. Every welding seam has passed the 100% undamage and crack detection or X-ray radial check to avoid any tiny defects and to make the machine more enduring.
The slewing bearing for the boom system is made by ROTHE ERDE Company from Germany or Larry Olisa Company from Italy. The 42CrMo texture of the slewing bearing ensures its higher strength and longer service life.
Designed on the basis of accurate data from finite element analysis and dynamics simulation analysis, the boom system has a scientific structure and excellent performance. Besides, stress and strain tests are conducted by the national test center to verify the agreement between the calculation and analysis result of the boom structure and its actual working condition. The design of Pump Truck adopts an international purchase strategy, and all its key components are world-famous brands which have the following features:
