Manual hydraulic pump manual

The birth of a good product without losing the good publicity, manual pump for such use in daily life less products, people will be unfamiliar with these products, many times users in the new product When using the more insecure, then this time for businesses this is a very good opportunity, through good publicity, not only can improve product visibility, but also can improve the value of the product, then Manual Hydraulic Pump Instructions What should be included for the right user. Manual Hydraulic Pump Manual 1, manual hydraulic pump Description: Manual hydraulic pump as a simple and convenient hydraulic power source is widely used in shipbuilding industry, coal mining machinery, petrochemical, metallurgy, electric power and heavy machinery and other fields. And its small size, light weight, easy to carry, security and other advantages are accepted by the majority of users. Manual hydraulic pump, the working pressure of 100 - 300Mpa; equipped with pressure reducing valve, in order to prevent pressure overload, the pump also has a safety valve; two flow design, a low pressure displacement of 33CC, two high pressure Displacement of 1.6CC; to achieve a constant power conditions, low pressure large flow of oil, high pressure small flow of oil, saving time and improve efficiency. Overall dimensions of 585 * 120 * 170mm, with a total oil weight of about 11Kg. Use shows that this pump is convenient and flexible, low labor-intensive, durable, is the ideal ultra-high pressure hydraulic power source. 2, manual hydraulic pump working principle: working principle: the cam driven by the motor rotation. As the cam pushes the plunger up, the seal formed by the plunger and the cylinder decreases in volume, the oil is squeezed out of the sealed volume and drained through the check valve to where it is needed. When the cam rotates to the descending part of the curve, the spring forces the plunger down to create a certain degree of vacuum, and the oil in the tank enters the sealed volume under atmospheric pressure. The cam continuously raises and lowers the plunger, periodically reduces and increases the volume of the seal, and the pump continues to suck and drain oil. 3, manual hydraulic pump repair: First, the maintenance of the following three points to find the cause of the malfunction, and the system to improve: a, check the boom cylinder leakage situation: the easiest way is to boom up and see its Is there a clear free fall? If the whereabouts of obvious removal of fuel tank inspection, seals have been found worn should be replaced. b, check the control valve: first clean the safety valve to check whether the spool wear, such as wear and tear should be replaced. If there is still no change after installation of safety valve, and then check the control valve spool wear, the gap limit of use is generally 0.06mm, severe wear and tear should be replaced. c, measuring the pressure of the hydraulic pump: If the pressure is low, then make adjustments, the pressure is still not adjustable, the serious wear and tear of the hydraulic pump. Through the above analysis, we can clearly understand that manual hydraulic pump is a widely used range of equipment, with China's rapid technological and economic development, the demand for such products will be more exuberant, then for businesses This is very beneficial news, but how to further expand the advantages and characteristics of this equipment, we need to do a lot of work. The road ahead is bound to have more difficulties and challenges.
