Since the 1980s and 1990s, small construction machinery has played a major advantage in the construction of municipal projects and transportation and has been able to develop rapidly. Small excavators have made great contributions to saving manpower and material resources in these projects, and have met various operating requirements of the city. They have been able to maximize their production capacity in a narrow working space in the city, and have gradually become representative in urban construction. Sex construction machinery. The development of small excavators mainly depends on the development of urban construction. Due to the city's transformation and construction construction, it requires short construction time, construction machinery has little impact on the surrounding environment, safety, low pollution, small radius of gyration, easy transportation and The coordinated appearance of the city's scenery and much more.
The status of mini excavators:
With the country’s purchase of commercial housing in 2011 and the slowdown in the speed of railway construction, the domestic construction market has seen a sharp drop in the demand for large and medium-sized excavators, coupled with the gradual entry of secondary excavators into the market, which has caused temporary saturation of the excavator market. Sales of excavators have been in a continuous downturn since mid-last year. With the transformation of new countryside, urban projects such as urban expansion, and the transformation of water conservancy and farmland, the demand for small excavators has risen against the trend and become the life-saving straw for excavator companies!
The Chinese excavator market is relatively rational, but the situation in the small excavator market is still somewhat worrying. In 2010, more than 20 provinces and municipalities included small excavators in the list of agricultural machinery purchase subsidies, which greatly stimulated the enthusiasm of enterprises to produce small excavators. Once subsidies are eliminated, small excavator manufacturers may face market risks.
387series Petroleum Submersed Pump
The electric submersible pump is called the electric submersible centrifugal pump, or the electric pump. It is a downhole lifting equipment that pumps the motor and pump together into the oil well below the liquid level. The electric submersible pump is a multi-stage centrifugal pump working in the downhole. The power supply is transferred into the well with the oil pipe. The ground power supply is transported to the underground submersible motor through the Transformer, the control panel and the submersible cable, so that the motor drives the multistage centrifugal pump to rotate, and the electric energy is converted to the mechanical energy, and the well fluid in the oil well is lifted to the ground.
