In spite of this, there is still a big gap between domestic slide valve pumps and foreign products. The main performance is:
Noise and vibration. Such as H-150 spool valve pump, most of the domestic products use anchor bolts, otherwise due to vibration, the pump crawls severely; fuel injection, oil leakage. When the pump is started, the fuel injection is serious and the oil leaks after operation. Most products have this problem; stopping the pump to return oil is serious, causing start-up difficulties, overloading the motor, and poor stability and reliability. Due to the backward production and processing equipment, not only the production efficiency is low, but also Poor interchangeability of parts affects the stability and reliability of the product.
Domestic slide valve pumps still have a big gap with foreign products
Some manufacturing companies have noticed the difference between the appearance quality of slide valve pumps and foreign products. They have grasped the appearance design of the product and the quality of the castings of the pump body in the appearance quality, and have developed the instrument appearance of the appearance to make the product structure attractive in design. The surface of the body is not putty, and it is assembled after painting, giving the appearance of the pump a refreshing feeling.
