Description

Technical Field

[0001] The utility model relates to the technical field of plunger pump protection, in particular to a horizontal five-cylinder plunger pump for a fracturing vehicle. Background Art

[0002] The plunger pump is one of the core components of oilfield pumping equipment. Through the reciprocating motion of the plunger in the cylinder, the working volume in the cylinder is alternately increased and decreased to transport the working fluid. The 2500HP plunger pump commonly used in the current oilfield equipment market has a stroke of 203.2mm, a maximum connecting rod load of about 85.6 tons, and an input power of 2500h.

[0003] Common horizontal five-cylinder plunger pumps in the prior art, such as the KQZ2500 pump, are reciprocating, positive displacement, single-acting, horizontal five-cylinder plunger pumps with a maximum input power of 2500hp. The pumps are widely used in intermittent oil well fracturing conditions and are usually installed on fracturing vehicles and moved with the vehicles.

[0004] However, in the prior art, because the KQZ2500 pump is large in size and is installed in a relatively compact space on the fracturing truck, the protection effect of the KQZ2500 pump is poor. In the windy and sandy environment of the oil field mining site, the KQZ2500 pump is easily damaged. The method of manually covering the dust cover is also inconvenient for the larger horizontal five-cylinder plunger pump. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a horizontal five-cylinder plunger pump for a fracturing vehicle to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. The first protective cloth is unfolded by a lifting assembly, and the second protective cloth is released from the winding box by the traction of the first electric push rod and covers the top and sides of the plunger pump, thereby wrapping and protecting the horizontal five-cylinder plunger pump. There is less human intervention in the process, and there will be no collision with the horizontal five-cylinder plunger pump. The horizontal five-cylinder plunger pump that is not in use can be better protected from dust.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a horizontal five-cylinder plunger pump for a fracturing vehicle, comprising a mounting plate, a horizontal five-cylinder plunger pump body is fixedly mounted on the top of the mounting plate, a connecting pipe mouth is arranged on one side of the horizontal five-cylinder plunger pump body, the mounting plate is fixed on the fracturing vehicle, and anti-collision frames are arranged on the three sides of the mounting plate away from the connecting pipe mouth, and sliding rods are fixed on the two middle ends of the anti-collision frames, the sliding rods are fixed on the mounting plate, a first protective cloth is slidably sleeved on the surface of the sliding rod, and a U-shaped frame is fixed on the top of the first protective cloth, the first protective cloth is wrapped around the side of the anti-collision frame, the top of the first protective cloth is covered with a second protective cloth, the anti-collision frame is provided with lifting assemblies at both ends of the connecting pipe mouth, and the lifting assemblies include a first electric push rod, and the extended end of the first electric push rod is fixed to the U-shaped frame.
