High-pressure hand pump, Lu Hydraulic (certified), hand pump provided by Lu of hydraulic equipment plant in Texas. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is specialized in "jacks, electric pumps, hand pumps, cylinders," the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Lu Jingli. Nothing is set in stone, as the manual hydraulic pump design is the same, always in the same position would be eliminated manual pump quality, so we have to continue to study and improve! (L) Improved manual pump design. After much argument hand pump, and finally the use of advanced priority valve with load sensing hydraulic steering gear in the form of the new system in accordance with the requirements of the steering, assign priority traffic, regardless of load size, wheel speed level can ensure adequate oil supply, The remainder of the circuit can use all work equipment supply, eliminating excessive oil due to steering circuit caused by power loss and improve the efficiency of the system offer a hand pump, reducing the hydraulic pressure of work. (2) optimize the design of the boom cylinders and hydraulic modeling, reduce system operating pressure. By optimizing the computing boom cylinder with standard series 80/4. Displacement hydraulic pump by 10ml / r increased to 14ml / r manual pump price, the system set pressure is 14MPa, to meet the boom cylinder lifting force and speed requirements. (3) hand pump should also be noted in the course of the proper use and maintenance of loaders, hydraulic oil regularly add or replace, maintain the cleanliness of hydraulic oil, strengthen the routine inspection and maintenance. High pressure hand pump is an ideal power source for electrical and mechanical assembly equipment currently used in the following aspects: 1, threaded fasteners and fastening tension power source device. Bolt preload can achieve precise control of the working pressure of the hydraulic oil can reach 300Mpa. At present, China's coal, electricity, chemical and other industries are made of high-strength hydraulic nuts or hydraulic tensioners, by high pressure hand pump do Nightwish power source, and achieved good results. 2, machinery and equipment conical surface smooth or cylindrical interference fit removable power source. Hydraulic nuts are an effective tool for bearings, gears, rotors and other smooth surfaces and tapered cylindrical interference fit disassembly. It consists of an annular piston seal embedded nut with internal threads and the composition. With a high pressure hand pump for the power source, high pressure and from the nut body surface or end into the circle, so that between the piston and the nut body relative motion, in order to achieve an interference fit of disassembly. 3, the hydraulic cylinder or jack load source. Is the ideal tool for heavy equipment installation and commissioning.
