The overall market of compound fertilizer is stable. So far, the social inventory of compound fertilizers is still available except in the northeast region. Relatively few are available in other regions. Overall, light stocks are relatively slow, due to the price of compound fertilizer this year compared with the same period. On the high side, agricultural products, fruits and vegetables also shrank significantly compared with the same period, farmers lacked idle funds, and dealers had difficulties in repatriating funds. As a result, dealers lacked confidence in the latter-stage market, coupled with dual-tariff export control, resulting in compound fertilizer companies from abroad. The market turned to the domestic market and enhanced the competitiveness of the domestic market. The only positive factor is that the current relatively high raw material costs of compound fertilizers are a strong support for the compound fertilizer market. The recent wholesale market price of diammonium is a force to the northeast region in the later period. The start-up of the compound fertilizer market is a strong support. The current 45%cl compound fertilizer price is 2450-2500 yuan/ton, the 45% sulfur mainstream price is 2610-2700 yuan/ton, and the 40%cl mainstream price is 2250-2300. Yuan / ton.
Raw materials: The recent urea steady rise, but the transaction price is temporarily stable, the ammonium phosphate market as a whole stable, diammonium rose, the mainstream price of 55 powder-ammonium is 2600-2650 yuan / ton, potassium chloride in the recent steady decline, but from In the long run, the potash fertilizer market is still relatively optimistic, and it may have a tendency to decline in the short term, but it is not very significant.
To sum up: For 2012, the overall market of compound fertilizer is mainly stable. From the perspective of domestic economic situation, the economy develops steadily, and the moderate inflationary monetary policy is moderately loose, which is conducive to the development of the enterprise. The situation of the late-stage compound fertilizer market is constrained by the trend of raw materials. The arrival of compound fertilizers in various regions.
The function of unloading valve for loader: the compressed air from the air pump enters the Air Brake Booster with constant pressure to ensure the safety of Loader Brake Clamp
Unloading valve for loader working principle: unloading relief valve is composed of relief valve and one-way valve. When the system pressure reaches the opening pressure of the relief valve, the relief valve is opened and the pump is unloaded; When the system pressure drops to the relief valve's closing pressure, the relief valve closes and the pump loads to the system.
Unloading valve is under certain conditions, can make hydraulic pump unloading valve. Unloading valve is usually a with two two-way valve solenoid valve is (often) the overflow valve, when the function is not unloading set system (pump) is used as the main stress, when unloading state (by two two-way valve action transformation) direct return tank pressure oil, the oil pump pressure drops to approximate to zero, in order to realize some loop control and improve the pump life, reduce power consumption.
In a circuit belonging to a merging circuit. The pressure reducing valve is used to adjust the pressure required by the executive element. It is connected in series in the loop and generally cannot be used interchangeably.
