PH value of the liquid pH 6.5-8.5. Chloride ion content of not more than 400 mg / liter. Pump "open" and "stop" should not be frequent. How it works: low pressure, high pressure pump through the high and low pressure oil Shaanxi double check valve while the oil port of the electric pump, when the working pressure greater than 2.5MPa Hunan dual port electric pumps, high pressure oil hydraulic control low pressure relief valve to open low-pressure oil pump mortar move back load (low oil situation does not work under high pressure oil also has its own open low pressure overflow valve function. The valve for your safety) (2) 34SZHP 6M pressure hand valve is in place Unloading style three-way valve, the valve is assigned dual port rotary vane electric pump, which is better stain resistance, commutation, reliable, easy maintenance, with packing function. Hunan double electric pump oil port, Texas aerospace hydraulic (certified), dual port is provided by an electric pump Dezhou City aerospace hydraulic machinery plant. Dezhou City aerospace hydraulic machinery plant (www.sdhtyeya.com) is a leader in Dezhou, hydraulic equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Texas aerospace hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the Texas aerospace hydraulic better future.
